RE: tcp md5 bgp attacks?

Just to point out - Data about md5 attacks from various organizations will depend on a number of factors such as - Is BGP TTL Security check being done? Are anti-spoofing ACLs enabled? uRPF enabled? Strict or Loose? BGP Session over a separate interface (tunnel)? With Gratitude, Pratik Lotia

Instead of rtbh I would suggest blocking/rate limiting common ports used in DDoS attacks. That will block 90% of the DDoS attacks. We recently open sourced a BGP Flowspec based tool for DDoS Mitigation. It applies Flowspec rules per victim IP Addr. https://github.com/racompton/docker-auto-flowsp

Should ISP block child pornography?

2018-12-06 Thread Lotia, Pratik M
Hello all, was curious to know the community’s opinion on whether an ISP should block domains hosting CPE (child pornography exploitation) content? Interpol has a ‘worst-of’ list which contains such domains and it wants ISPs to block it. On one side we want the ISP to not do any kind of censorshi
