Placing Members-Discuss in Moderation
by Piotr Strzyżewski 08 May '20

08 May '20

Dear members, Today, the Executive Board held a formal meeting in order to officially resolve the appointment of Hans Petter Holen as Managing Director of the RIPE NCC. In light of recent activity on the members-discuss mailing list, we also resolved to place the members-discuss mailing list in moderation until 1 June. This follows numerous complaints that have been made about mails that are off-topic and/or contain material that does not show tolerance or respect for fellow members of the list. The resolution and accompanying text is contained in the draft minutes: https://www.ripe.net/about-us/executive-board/minutes/2020/minutes-134th-ex… With this resolution, the principles of the RIPE Mailing List/RIPE Forum Code of Conduct will be applied to the members-discuss list. Emails that do not meet the requirements of that code of conduct will not be approved to be posted to the list. Mails that do not meet the intended purpose of providing members with a means to discuss membership issues among themselves will also not be approved to be posted to the list. The moderators of the list will be the Executive Board Secretary and one senior member of RIPE NCC staff. Mails will be moderated during office hours. A separate archive of all mails including those rejected by the moderators is available for all members to view should they wish to do so: https://www.ripe.net/ripe/mail/archives/members-discuss-unmoderated/ The Board is obviously aware that there is an election taking place at the General Meeting and there are also matters of importance to discuss such as the RIPE NCC Financial Report 2019 and the RIPE NCC Charging Scheme 2021. We are determined to ensure that we remain neutral in facilitating this membership discussion list, and we also hope that members will abide by the purpose of the list and the principles of the code of conduct. Regards, Piotr Strzyżewski RIPE NCC Executive Board Secretary

Technical solution to resolve ELAD-19 related spam and harassment in mailboxes
by Dominic Schallert 01 May '20

01 May '20

Dear community, today I want to present you with our technical solution to prevent ELAD-19 related spam and harassment from flooding inboxes. This technical solution is minimal invasive and can be implemented on all mail servers running spamassassin with ease. Please find the following spamassassin header and body rules below: header SC_HEADER_100 From =~ /Elad Cohen/ describe SC_HEADER_100 ELAD-19 Campagin score SC_HEADER_100 100 header SC_HEADER_101 From =~ /elad\(a)netstyle.io/ describe SC_HEADER_101 ELAD-19 Campagin score SC_HEADER_101 100 body SC_BODY_102 /Elad Cohen/i describe SC_BODY_102 ELAD-19 Campagin score SC_BODY_102 100 While I really appreciate encouraged people coming up with innovative ideas and proposals within the network operators community, this particular discussion including repeated harassment against members of the community - from my personal point of view - is just not the culture we should establish within this community. Please note that the solution presented above is just our new way of dealing with this matter, it’s neither a proposal nor a recommendation for others. All the best and wish you a happy (and hopefully spam free) weekend!

Re: [members-discuss] Elad / His Ideas ?
by Ali Vargonen 01 May '20

01 May '20

* Sorry to take anyone's valuable time, but I think this is necessary. Hello Elad, Please read my email carefully I would be very happy if you can answer my questions, this way it would be much clear for everyone in the list to understand, what you are trying to achieve. 1) VERY Important, I am not attacking you. I am going to ask questions to learn more about your idea and yourself. 2) I don't support any candidate so I am not voting for anyone else or you. So; don't tell me that I will support someone else, thus I am asking you questions. 3) I don't have a hidden agenda about IP V4 or V6, and I personally don't sell them. Let's start with questions; I will share your answers with my friends who work in the network field. We have a small group of 40 people and our total experince in routing is 650 years. - You have an idea, OK. 1) Did you make any research about to implement your idea, in regards to economics, and adaptation rates around the globe? 2) Do you personally or worked with a team of people who designed the chips on the routers or the software runs on them, I want to learn this very much, maybe you have designed a software which we don't know, that is running currently and you want to improve it. 3) Do you personally own or work with a team of people who have patents for the current protocols including the ones you mention and try to improve? 4) Do you have a team to implement your idea work together, if yes please share their names with details on a website, so we could understand how good you structure your team to make your ideas true? 5) Do you or your "maybe" existing team know how routers work, if you wish we can choose cisco, juniper, extreme, brocade anything you wish, I want to learn did you studied about their current working software setup dealing with BGP and how they manage the traffic and do you have a blueprint of the changes that you want to be implemented in regards to packet processing and cam/fib tables? 6) Did you contact any vendor about your idea before implementing your changes to their equipment via hardware or software solution? 7) If you contacted them what kind of replies did you get? ( You tell us nobody understands your idea, maybe they understand, so I want to learn) or did they attack you also? 8) Did you ever worked in a network ecosystem with more than 5+ BGP peers and also 100G + network traffic before, if yes could you please explain me how does your idea fit with the ack of the source in this amount of traffic, you can calculate the number of packets per seconds yourself if you know. 9) How do you plan to run the backend do you have any kind of blueprint, design or project about that, let us see that also? It can be just your notes, can you give an URL that we can read about it? 10) Do you have a working model of this "idea" in any kind of test lab you have or rented that works on software-based routing devices? Virtual Routers? What are the results you get there? Any information on this? I am asking all these questions to you to learn more about you and your project. My notes for you; - You don't need to be a ripe chair if you want to change the world in regards to networking to a better place, you don't need titles Elad, you just need really good ideas that people respect and which you could provide with more detailed information. - Also please don't tell everyone is attacking you, if you think they are, why you are saying this" they are attacking me because of"; instead fight with your ideas, bright thoughts, what you bring on the table? But also please don't forget that, as a leader or a chair, whatever you call, you must; - Respect people, if they agree or disagree with you; - Listen and understand why they are reacting to you that way; - Always try to be co-operative, and you may answer them like this, "I respect your answer but we don't agree on this topic." This is better than writing "They are attacking me 100x times" If you want to be successful in your campaign, you must not do it over member's forum, you can lunch a website, do it over twitter, create a blog, or what you think fits you; fill it with content, and share as much as possible information. Please let us know you and your ideas more. If we have questions about it we could ask it over there, don't take people's valuable time with these arguments. Respecting your community must be your rule number one if you plan to lead them. Don't worry, If people have an interest in your ideas they will contact you. As I told you while starting this email, I am not attacking you, just trying to know more about yourself and your idea. IF; You answer this email with; 1) You are attacking me. 2) I don't have to provide any detailed information about my idea. 3) I don't have to respect anyone and will just answer like before. 4) I don't need to explain anything you will see how I achive them when I am the chair of RIPE. Sorry, but as lots of people do I will choose not to answer you back again. Please think 2-3 times and then answer. Show us that why we must vote for you because of your intelligence, personality, interpersonal skills, leadership and also way you communicate with your community? Regards, Ali.

Hello, Even all of us to seeing this discussion as spam. I think it is useful and all candidates for election must write their ideas and point of views too. Now I can clearly make my judgment if to give my vote for mr Elad Khoen or not. PS: The spamming come from all who try to respond to these technical ideas. So please stop ! Just read make your mind and lets hear the others candidates.

Technical solution to resolve Spoofed IP traffic, Spoofed amplification DDoS attacks, BGP&RIR hijacking, IoT botnet infections and Botnet C&Cs
by Elad Cohen 01 May '20

01 May '20

Hello Ripe Members! I will share the following solution in the near General Meeting and I'm interested to share the following technical solution with you as well, it will completely resolve: Spoofed IP traffic, Spoofed amplification DDoS attacks, BGP&RIR hijacking. And will dramatically lower: IoT botnet infections and Botnet C&Cs. By a single update to any BGP router, not any router needs to be updated, only active BGP routers. If I will have the honor of being elected to the Ripe Board I will harness all the power of Ripe and all of the 5 RIR's and all of the LIR's in the 5 RIR's so routing manufacturing companies will implement the below processes and methods with a single firmware update to their BGP routers. I'm asking for your support in electing me so I will be able to enter the Ripe Board and then I will be able to make everything which is written in this post to come true. Regarding the bgp-anycasted infrastructure written below, ICANN is written but the global bgp-anycasted infrastructure can be managed by the 5 RIR's and/or by the ccTLDs registries (my main point is that who will operate the bgp-anycasted infrastructure is not important for now, as long as it will be an agreed authoritative non-governmental non-commercial global entity/ies) With new tracking protocol over ip, routers will be able to confirm that source ip came from the network of the announcing ASN, and hence spoofed amplification DDoS attacks will be completely annihilated. The Process: At the source BGP router, for any ip packet with a source address that is from the network of the source BGP router (lets call it original ip packet) - the source BGP router will create a new ip packet (lets call it tracking ip packet) with a new transport layer protocol and with the same source address and with the same destination address and with the same IP-ID such as the original ip packet. In the new tracking ip packet there will be a new transport layer protocol (tracking protocol) with the following fields: AS number of source BGP router in clear text AS number of source BGP router encrypted with the private key of the source BGP router The destination BGP router (a BGP router that the destination address is in its network) whenever it receive a 'tracking ip packet' will check if its have the internal boolean 'Check tracking flag' in it - 'on' or 'off': If 'off' then the destination BGP router will drop that 'tracking ip packet' If 'on' then the destination BGP router will decrypt the 'encrypted AS number' with the public key of the specific AS number and after decryption the AS number need to be the result: if not then to drop the tracking ip packet and the original ip packet related to it if yes then to drop the tracking ip packet and to forward the related original ip packet to destination but only if the source address is originated from the specific ASN (according to the local ASNs+ranges table in the BGP router, such table will be received from ICANN) If the 'Check tracking flag' is set to 'on' then any original ip packet that arrive to the destination BGP router will wait for the related tracking ip packet (in case the related tracking ip packet didn't already arrived to the destination BGP router). The destination BGP router will manage such waiting for X number of seconds. The destination BGP router will match between a tracking ip packet and an original ip packet - based on their source address and their destination address and their IP-ID which will all be identical. More Aspects: - The end-devices will not need to be updated, any router will not need to be updated, only all the BGP routers will need to be updated. - Any BGP router in the routing path, which the original ip packet and the tracking ip packet are not destined to an ip address in its own network - will not check the content of the tracking ip packet and will forward both the tracking ip packet and the original ip packet as they are. - Each BGP router will have all the public keys (of all the ASN's) locally. - Each BGP router will have a full list of all the ASN's and all the route objects ranges which are related to them locally. How BGP routers will receive all the ranges in all the route objects of all the ASNs (in the 5 RIRs) and all the public keys of all the ASNs (for decrypting the encrypted strings in 'tracking ip packets'): - Each BGP router will create a tcp session with ICANN backend infrastructure (the backend infrastructure of ICANN will use BGP anycast and will be available from many locations worldwide with automatic syncing) - At this stage there will be a handshake process between the BGP router and the ICANN backend infrastructure in order for ICANN to know the correct ASN which is operating the BGP router - the BGP router will send its ASN in cleartext and also its ASN encrypted with its ICANN-communication-private-key , ICANN will know the related public key for the specific ASN from the specific ASN object in the RIR (the public key for communication with ICANN will be displayed there) - after decryption ICANN will compare the decrypted string to the AS Number for successful authentication. - After successful authentication, all the communication will be encrypted, ICANN will notify the BGP router about its public key and ICANN will use the public key of the ASN for the communication with ICANN - from the ASN object in the RIR. - The BGP router will send over the session its public key to be used by other BGP routers in order to decrypt the encrypted string in the tracking ip packets that it will originate (that private key and public key will be managed in the BGP router GUI or CLI). - ICANN will notify all the other BGP routers through the sessions with them about a newly updated such public key of any other BGP router. - ICANN will also receive in real-time any route object creation/modification/deletion notification from any of the 5 RIRs and will then update all the BGP routers through all of their sessions. - In case a BGP router doesn't have an active session to ICANN backend infrastructure (for any reason, might be due to networking issue) - then temporarily the internal 'Check tracking flag' of it will be set to 'off'. After the session with ICANN backend infrastructure will be re-established and the BGP router will receive all the meantime updates - the boolean value of 'Check internal flag' will return to initial state. - Any update from ICANN backend infrastructure to a BGP router (such as a public key of another BGP router, or a routing object update) - will be confirmed that the update was received well by the BGP router side. 'Check tracking flag' in BGP Routers: - BGP routers, in their GUI and CLI interfaces - will not allow the end-user to set the boolean value of 'Check tracking flag', in order to avoid misconfiguration. - The ICANN backend infrastructure through the session with the BGP router - will be able to set the boolean value of the 'Check tracking flag'. - The reason for it, is that if 'Check tracking flag' will be set on some destination BGP routers while some other source BGP routers weren't upgraded yet (and will not send the 'tracking ip packet' due to it) - then 'tracking ip packet' will never reach the destination BGP router and the internet will break. - Central setting of 'Check tracking flag' through ICANN backend infrastructure - will allow ICANN to inform all the BGP routers at once to switch 'on' the 'Check tracking flag' - ICANN, in the session to any BGP router, will also receive the percentage of ip packets that were destained to that BGP router network - that also had ip tracking packets, in this way ICANN will know when all the BGP routers were properly globally updated and when it is time to enable the 'Check tracking flag' in all the BGP routers. - ICANN will know if all the BGP routers in the world were upgraded based on keeping the full BGP table and comparing it to all the BGP routers that did and that did not open a session to ICANN backend infrastructure. Automatic preventation of IoT botnet infections: - IoT botnets are based on default credentials, if we can block default credentials of IoT devices then these kind of botnets (such as Mirai-variants and similar) will stop to have an impact in the internet. - The data field in an ip packet - will always be the same for an access attempt to a IoT device with default credentials - hence these kind of "IP protocol data fingerprints" which are related to specific "IP protocol numbers" will be provided by ICANN backend infrastructure to each BGP router through the opened session with it. - There are two issues with matching incoming ip packets to the "locally stored IP protocol data fingerprints" - the first one is that ip packets can be sent by fragments (so not all the data field will be sent at once in order to be able to be compared with the locally stored data fingerprints) and the second is that usernames (or url's) or any other textual data in the incoming ip packet data field can be in uppercase or in lowercase.

Regarding the second issue - the stored data fingerprints in the local BGP router will be stored in a way that some bytes of them (in specific indexes) will not be compared and in case all the other bytes will match - then the bytes in these indexes - will first be lowered case - and only then comparison will be made to the specific indexed bytes in the specific ip packet data fingerprint. - In case a IoT device behind a BGP router will be infected somehow (for example when a specific fingerprint data with default credentials for a specific device wasn't updated yet through ICANN backend infrastructure), it will be able to infect all the other IoT devices in the local network when the connectivity to them is not through the BGP router, that kind of impact will be much much lower than infected IoT device which can infect any other IoT device in the internet and then massive botnets in the internet are created which are being used for DDoS. Automatic prevention of botnet C&C ip addresses: - Botnets C&C are also a problem in the internet. - This problem can be overcome using the following technical addition: the 5 RIR's will operate end-users honeypots machines all over the world (it will be implemented by a single physical machine in each location, for example in each datacenter and in each major ISP, each single physical machine will emulate a virtual router and virtual VM's, the virtual VM's will emulate many different kinds of 'real world machines', any kind of automatic updating (in the operating system configurations) will be disabled, these honeypots machines are not intended to make any outgoing connection, the virtual routers will monitor if any outgoing connection is made and if yes then it is to a botnet C&C, the virtual router will update the ICANN backend infrastructure regarding it and the ICANN backend infrastructure will update all the BGP routers (in their open sessions) regarding it to completely block any communication to that botnet C&C ip address. There will be a web-based system and only the related Law Enforcement Agency of that C&C ip address region - will be able to remove that C&C ip address from being blocked after their manual check. - Honeypot machines will be deployed using 'templates' - these templates must be signed and not anyone can create them, they should be created and signed by an agreed Law Enforcement Agency such as Interpol in order to make sure that these templates are by-design not making any outgoing connection. The templates will be deployed in an automatic way (major ISP's and datacenters will be able to easily add a 'physical honeypot' server in their network, that will be shipped to them), the re-initiation of a compromised 'virtual machine' that made an outgoing connection - will also be automatic through the system in the physical server.

I will share the following solution in the near General Meeting and I'm interested to share the following technical solution with you as well, it will completely resolve: Spoofed IP traffic, Spoofed amplification DDoS attacks, BGP&RIR hijacking. And will dramatically lower: IoT botnet infections and Botnet C&Cs. By a single update to any BGP router, not any router needs to be updated, only active BGP routers. If I will have the honor of being elected to the Ripe Board I will harness all the power of Ripe and all of the 5 RIR's and all of the LIR's in the 5 RIR's so routing manufacturing companies will implement the below processes and methods with a single firmware update to their BGP routers. I'm asking for your support in electing me so I will be able to enter the Ripe Board and then I will be able to make everything which is written in this post to come true. Regarding the bgp-anycasted infrastructure written below, ICANN is written but the global bgp-anycasted infrastructure can be managed by the 5 RIR's and/or by the ccTLDs registries (my main point is that who will operate the bgp-anycasted infrastructure is not important for now, as long as it will be an agreed authoritative non-governmental non-commercial global entity/ies) With new tracking protocol over ip, routers will be able to confirm that source ip came from the network of the announcing ASN, and hence spoofed amplification DDoS attacks will be completely annihilated. The Process: At the source BGP router, for any ip packet with a source address that is from the network of the source BGP router (lets call it original ip packet) - the source BGP router will create a new ip packet (lets call it tracking ip packet) with a new transport layer protocol and with the same source address and with the same destination address and with the same IP-ID such as the original ip packet. In the new tracking ip packet there will be a new transport layer protocol (tracking protocol) with the following fields: AS number of source BGP router in clear text AS number of source BGP router encrypted with the private key of the source BGP router The destination BGP router (a BGP router that the destination address is in its network) whenever it receive a 'tracking ip packet' will check if its have the internal boolean 'Check tracking flag' in it - 'on' or 'off': If 'off' then the destination BGP router will drop that 'tracking ip packet' If 'on' then the destination BGP router will decrypt the 'encrypted AS number' with the public key of the specific AS number and after decryption the AS number need to be the result: if not then to drop the tracking ip packet and the original ip packet related to it if yes then to drop the tracking ip packet and to forward the related original ip packet to destination but only if the source address is originated from the specific ASN (according to the local ASNs+ranges table in the BGP router, such table will be received from ICANN) If the 'Check tracking flag' is set to 'on' then any original ip packet that arrive to the destination BGP router will wait for the related tracking ip packet (in case the related tracking ip packet didn't already arrived to the destination BGP router). The destination BGP router will manage such waiting for X number of seconds. The destination BGP router will match between a tracking ip packet and an original ip packet - based on their source address and their destination address and their IP-ID which will all be identical. More Aspects: - The end-devices will not need to be updated, any router will not need to be updated, only all the BGP routers will need to be updated. - Any BGP router in the routing path, which the original ip packet and the tracking ip packet are not destined to an ip address in its own network - will not check the content of the tracking ip packet and will forward both the tracking ip packet and the original ip packet as they are. - Each BGP router will have all the public keys (of all the ASN's) locally. - Each BGP router will have a full list of all the ASN's and all the route objects ranges which are related to them locally. How BGP routers will receive all the ranges in all the route objects of all the ASNs (in the 5 RIRs) and all the public keys of all the ASNs (for decrypting the encrypted strings in 'tracking ip packets'): - Each BGP router will create a tcp session with ICANN backend infrastructure (the backend infrastructure of ICANN will use BGP anycast and will be available from many locations worldwide with automatic syncing) - At this stage there will be a handshake process between the BGP router and the ICANN backend infrastructure in order for ICANN to know the correct ASN which is operating the BGP router - the BGP router will send its ASN in cleartext and also its ASN encrypted with its ICANN-communication-private-key , ICANN will know the related public key for the specific ASN from the specific ASN object in the RIR (the public key for communication with ICANN will be displayed there) - after decryption ICANN will compare the decrypted string to the AS Number for successful authentication. - After successful authentication, all the communication will be encrypted, ICANN will notify the BGP router about its public key and ICANN will use the public key of the ASN for the communication with ICANN - from the ASN object in the RIR. - The BGP router will send over the session its public key to be used by other BGP routers in order to decrypt the encrypted string in the tracking ip packets that it will originate (that private key and public key will be managed in the BGP router GUI or CLI). - ICANN will notify all the other BGP routers through the sessions with them about a newly updated such public key of any other BGP router. - ICANN will also receive in real-time any route object creation/modification/deletion notification from any of the 5 RIRs and will then update all the BGP routers through all of their sessions. - In case a BGP router doesn't have an active session to ICANN backend infrastructure (for any reason, might be due to networking issue) - then temporarily the internal 'Check tracking flag' of it will be set to 'off'. After the session with ICANN backend infrastructure will be re-established and the BGP router will receive all the meantime updates - the boolean value of 'Check internal flag' will return to initial state. - Any update from ICANN backend infrastructure to a BGP router (such as a public key of another BGP router, or a routing object update) - will be confirmed that the update was received well by the BGP router side. 'Check tracking flag' in BGP Routers: - BGP routers, in their GUI and CLI interfaces - will not allow the end-user to set the boolean value of 'Check tracking flag', in order to avoid misconfiguration. - The ICANN backend infrastructure through the session with the BGP router - will be able to set the boolean value of the 'Check tracking flag'. - The reason for it, is that if 'Check tracking flag' will be set on some destination BGP routers while some other source BGP routers weren't upgraded yet (and will not send the 'tracking ip packet' due to it) - then 'tracking ip packet' will never reach the destination BGP router and the internet will break. - Central setting of 'Check tracking flag' through ICANN backend infrastructure - will allow ICANN to inform all the BGP routers at once to switch 'on' the 'Check tracking flag' - ICANN, in the session to any BGP router, will also receive the percentage of ip packets that were destained to that BGP router network - that also had ip tracking packets, in this way ICANN will know when all the BGP routers were properly globally updated and when it is time to enable the 'Check tracking flag' in all the BGP routers. - ICANN will know if all the BGP routers in the world were upgraded based on keeping the full BGP table and comparing it to all the BGP routers that did and that did not open a session to ICANN backend infrastructure. Automatic preventation of IoT botnet infections: - IoT botnets are based on default credentials, if we can block default credentials of IoT devices then these kind of botnets (such as Mirai-variants and similar) will stop to have an impact in the internet. - The data field in an ip packet - will always be the same for an access attempt to a IoT device with default credentials - hence these kind of "IP protocol data fingerprints" which are related to specific "IP protocol numbers" will be provided by ICANN backend infrastructure to each BGP router through the opened session with it. - There are two issues with matching incoming ip packets to the "locally stored IP protocol data fingerprints" - the first one is that ip packets can be sent by fragments (so not all the data field will be sent at once in order to be able to be compared with the locally stored data fingerprints) and the second is that usernames (or url's) or any other textual data in the incoming ip packet data field can be in uppercase or in lowercase.

The Process: At the source BGP router, for any ip packet with a source address that is from the network of the source BGP router (lets call it original ip packet) - the source BGP router will create a new ip packet (lets call it tracking ip packet) with a new transport layer protocol and with the same source address and with the same destination address and with the same IP-ID such as the original ip packet. In the new tracking ip packet there will be a new transport layer protocol (tracking protocol) with the following fields: AS number of source BGP router in clear text AS number of source BGP router encrypted with the private key of the source BGP router The destination BGP router (a BGP router that the destination address is in its network) whenever it receive a 'tracking ip packet' will check if its have the internal boolean 'Check tracking flag' in it - 'on' or 'off': If 'off' then the destination BGP router will drop that 'tracking ip packet' If 'on' then the destination BGP router will decrypt the 'encrypted AS number' with the public key of the specific AS number and after decryption the AS number need to be the result: if not then to drop the tracking ip packet and the original ip packet related to it if yes then to drop the tracking ip packet and to forward the related original ip packet to destination but only if the source address is originated from the specific ASN (according to the local ASNs+ranges table in the BGP router, such table will be received from ICANN) If the 'Check tracking flag' is set to 'on' then any original ip packet that arrive to the destination BGP router will wait for the related tracking ip packet (in case the related tracking ip packet didn't already arrived to the destination BGP router). The destination BGP router will manage such waiting for X number of seconds. The destination BGP router will match between a tracking ip packet and an original ip packet - based on their source address and their destination address and their IP-ID which will all be identical. More Aspects: - The end-devices will not need to be updated, any router will not need to be updated, only all the BGP routers will need to be updated. - Any BGP router in the routing path, which the original ip packet and the tracking ip packet are not destined to an ip address in its own network - will not check the content of the tracking ip packet and will forward both the tracking ip packet and the original ip packet as they are. - Each BGP router will have all the public keys (of all the ASN's) locally. - Each BGP router will have a full list of all the ASN's and all the route objects ranges which are related to them locally. How BGP routers will receive all the ranges in all the route objects of all the ASNs (in the 5 RIRs) and all the public keys of all the ASNs (for decrypting the encrypted strings in 'tracking ip packets'): - Each BGP router will create a tcp session with ICANN backend infrastructure (the backend infrastructure of ICANN will use BGP anycast and will be available from many locations worldwide with automatic syncing) - At this stage there will be a handshake process between the BGP router and the ICANN backend infrastructure in order for ICANN to know the correct ASN which is operating the BGP router - the BGP router will send its ASN in cleartext and also its ASN encrypted with its ICANN-communication-private-key , ICANN will know the related public key for the specific ASN from the specific ASN object in the RIR (the public key for communication with ICANN will be displayed there) - after decryption ICANN will compare the decrypted string to the AS Number for successful authentication. - After successful authentication, all the communication will be encrypted, ICANN will notify the BGP router about its public key and ICANN will use the public key of the ASN for the communication with ICANN - from the ASN object in the RIR. - The BGP router will send over the session its public key to be used by other BGP routers in order to decrypt the encrypted string in the tracking ip packets that it will originate (that private key and public key will be managed in the BGP router GUI or CLI). - ICANN will notify all the other BGP routers through the sessions with them about a newly updated such public key of any other BGP router. - ICANN will also receive in real-time any route object creation/modification/deletion notification from any of the 5 RIRs and will then update all the BGP routers through all of their sessions. - In case a BGP router doesn't have an active session to ICANN backend infrastructure (for any reason, might be due to networking issue) - then temporarily the internal 'Check tracking flag' of it will be set to 'off'. After the session with ICANN backend infrastructure will be re-established and the BGP router will receive all the meantime updates - the boolean value of 'Check internal flag' will return to initial state. - Any update from ICANN backend infrastructure to a BGP router (such as a public key of another BGP router, or a routing object update) - will be confirmed that the update was received well by the BGP router side. 'Check tracking flag' in BGP Routers: - BGP routers, in their GUI and CLI interfaces - will not allow the end-user to set the boolean value of 'Check tracking flag', in order to avoid misconfiguration. - The ICANN backend infrastructure through the session with the BGP router - will be able to set the boolean value of the 'Check tracking flag'. - The reason for it, is that if 'Check tracking flag' will be set on some destination BGP routers while some other source BGP routers weren't upgraded yet (and will not send the 'tracking ip packet' due to it) - then 'tracking ip packet' will never reach the destination BGP router and the internet will break. - Central setting of 'Check tracking flag' through ICANN backend infrastructure - will allow ICANN to inform all the BGP routers at once to switch 'on' the 'Check tracking flag' - ICANN, in the session to any BGP router, will also receive the percentage of ip packets that were destained to that BGP router network - that also had ip tracking packets, in this way ICANN will know when all the BGP routers were properly globally updated and when it is time to enable the 'Check tracking flag' in all the BGP routers. - ICANN will know if all the BGP routers in the world were upgraded based on keeping the full BGP table and comparing it to all the BGP routers that did and that did not open a session to ICANN backend infrastructure. Automatic preventation of IoT botnet infections: - IoT botnets are based on default credentials, if we can block default credentials of IoT devices then these kind of botnets (such as Mirai-variants and similar) will stop to have an impact in the internet. - The data field in an ip packet - will always be the same for an access attempt to a IoT device with default credentials - hence these kind of "IP protocol data fingerprints" which are related to specific "IP protocol numbers" will be provided by ICANN backend infrastructure to each BGP router through the opened session with it. - There are two issues with matching incoming ip packets to the "locally stored IP protocol data fingerprints" - the first one is that ip packets can be sent by fragments (so not all the data field will be sent at once in order to be able to be compared with the locally stored data fingerprints) and the second is that usernames (or url's) or any other textual data in the incoming ip packet data field can be in uppercase or in lowercase. In order to overcome the possibility of the existence of a single data fingerprint in multiple incoming ip packet fragments - then in case the BGP router is recognizing the incoming fragmented ip packet data value as part of an existing fingerprint data in its local database then it will keep track of the arrival ip packet fragments based on their specific IP-ID identifier and the BGP router will not forward the last ip packet fragment if the last ip packet fragment will cause all the related ip packet fragments to match a specific ip fingerprint data (last ip packet doesn't have to be the last fragmented part but it is the last ip packet that arrived with that IP-ID identifier, so the BGP router will keep track of the specific fragmented IP packets that arrived and their indexes in order to know when the last one of them arrived). Regarding the second issue - the stored data fingerprints in the local BGP router will be stored in a way that some bytes of them (in specific indexes) will not be compared and in case all the other bytes will match - then the bytes in these indexes - will first be lowered case - and only then comparison will be made to the specific indexed bytes in the specific ip packet data fingerprint. - In case a IoT device behind a BGP router will be infected somehow (for example when a specific fingerprint data with default credentials for a specific device wasn't updated yet through ICANN backend infrastructure), it will be able to infect all the other IoT devices in the local network when the connectivity to them is not through the BGP router, that kind of impact will be much much lower than infected IoT device which can infect any other IoT device in the internet and then massive botnets in the internet are created which are being used for DDoS. Automatic prevention of botnet C&C ip addresses: - Botnets C&C are also a problem in the internet. - This problem can be overcome using the following technical addition: the 5 RIR's will operate end-users honeypots machines all over the world (it will be implemented by a single physical machine in each location, for example in each datacenter and in each major ISP, each single physical machine will emulate a virtual router and virtual VM's, the virtual VM's will emulate many different kinds of 'real world machines', any kind of automatic updating (in the operating system configurations) will be disabled, these honeypots machines are not intended to make any outgoing connection, the virtual routers will monitor if any outgoing connection is made and if yes then it is to a botnet C&C, the virtual router will update the ICANN backend infrastructure regarding it and the ICANN backend infrastructure will update all the BGP routers (in their open sessions) regarding it to completely block any communication to that botnet C&C ip address. There will be a web-based system and only the related Law Enforcement Agency of that C&C ip address region - will be able to remove that C&C ip address from being blocked after their manual check. - Honeypot machines will be deployed using 'templates' - these templates must be signed and not anyone can create them, they should be created and signed by an agreed Law Enforcement Agency such as Interpol in order to make sure that these templates are by-design not making any outgoing connection. The templates will be deployed in an automatic way (major ISP's and datacenters will be able to easily add a 'physical honeypot' server in their network, that will be shipped to them), the re-initiation of a compromised 'virtual machine' that made an outgoing connection - will also be automatic through the system in the physical server.
