Internet Security Lectures (in the process of being updated for class of Fall'24)
Internet inter-domain routing (BGP) security. This is a long presentation introducing inter-domain routing (BGP), its security concerns, different misrouting attacks and defenses (RPKI, ASPA, BGPsec, ...), as well as data-layer (IP) attacks, mainly IP spoofing, and defenses (uRPF and other Source Address Validation (SAV) techniques, including the BAR-SAV draft).
Web security attacks and defenses. Quite a lot yet only the tip of the iceberg! [updated 10/8/25]
DNS security attacks (mostly poisoning) and defenses (incl. DNSSEC). [updated Aug 17, 2025]
Firewalls - and a bit on IDS/IPS and Honeypots (aka, basic tools) [updated 10/24]
TCP/IP security (and few quick words QUIC too). Incl. fragmentation attacks (also applied to DNS), spoofing/SAV (incl. uRPF), TCP injections and more.
Denial of Service attacks and defenses. Quite comprehensive, I think; but it's such wide and dynamic area...
LAN security . A rather short presentation; mainly ARP and other LAN-poisoning attacks.
