AWS Web Application Firewall blocks ISP ranges?
by Jonathan Kalbfeld 21 Mar '24

21 Mar '24

Hi All, I just became aware that AWS has a list of hosting IP providers and that list is blocked by their WAF? (!?!?). None of my VM or colo customers can reach anything in AWS, such as Docker, Twilio, etc. I confirmed through source routing that when I access it using one of my peering partners as a source IP it is reachable, but using one of my net blocks, it is not reachable and times out. Checked all of my routing tables and those AWS blocks are definitely visible. Also confirmed from looking glass that my IP ranges are showing up. Has anyone else encountered that? If so, is there a way to get removed from that list? I have a very curated list of clients and I know all of them personally and none of them have been abusing AWS, so I was wondering if it was some kind of blanket ban? If you're internal to AWS, my ASN is 54380, IP ranges affected are 199.33.244.0/24, 199.79.202.0/24, 199.188.96.0/22, 45.59.144.0/22 and 206.197.110.0/24 Feel free to reach out off-list.

Re: Best TAC Services from Equipment Vendors

Since then, I have had to go through a not insignificant evaluation period of TAC engineers > before I let them take control of a remote session, and it is now simply pure instinct to log SSH sessions. Picture it, Cisco TAC, on a troubleshooting call, runs 'no ip routing' and hits enter before our engineer could scream "NO" at 11:30AM on a core L3 on a college campus. RCA afterwards: 1. "Always log all terminals (we prefer SecureCRT) from Windows bastion host to OneDrive or Google Drive" 2. New CiscoTAC TACACS login created allowing Enable but Denying "configure" as a command. When you troubleshoot, you log in as CiscoTAC. The CiscoTAC tacacs profile description in Clearpass makes it clear why it's there. I left the curse words out. -J John C.

Google's security.txt

Anyone from Google, You might want to fix a tiny typo in your security.txt. RFC9116 uses American spelling, not British spelling, like you did. Check here: https://www.uriports.com/tools?method=securitytxt&domain=google.com It's only a small issue, but it might spread when people start using Google's security.txt for inspiration. -- 𝓜𝓪𝓻𝓬𝓸
