In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can.

EDU zone operational announcement: DNSSEC algorithm rollover
by Wessels, Duane 05 Sep '23

05 Sep '23

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Verisign will soon begin the transition to DNSSEC algorithm 13 (ECDSA) for the EDU zone. Over the next few days, algorithm 13 signatures will start to appear in the zone, followed by the algorithm 13 DNSKEY records. We expect the DS record for the EDU zone to change from algorithm 8 to algorithm 13 between September 12-15. Additional information can be found at our blog post and DNS-OARC presentation URLs below: https://blog.verisign.com/security/dnssec-algorithm-update/ https://indico.dns-oarc.net/event/47/contributions/1012/ We expect no operational impacts for end users, but please feel free to reach out to us with concerns or any observations of anomalous behavior related to this algorithm rollover.
