Presentations: Lectures, Tutorials and Others

Cybersecurity Lectures:

• Internet Security Lectures (in the process of being updated for class of Fall'24)

  • Internet inter-domain routing (BGP) security (updated 11/18/24). This presentation focuses of misrouting attacks and defenses against them (RPKI, BGPsec, ...); it does not cover Source Address Validation (SAV), which I hope to add soon as a separate updated presentation. SAV is also covered as part of an older powerpoint presentation on BGP security.  

  • Web security attacks and defenses. Quite a lot yet only the tip of the iceberg! [updated 9/24]

  • DNS security attacks (mostly poisoning) and defenses (incl. DNSSEC). [updated 10/24]

  • 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...

  • ‘Knowledge is Power’: Reconnaissance and Scanning 

  • Vulnerabilities, Malware and Cyber-security Ethics

  • LAN security . A rather short presentation; mainly ARP and other LAN-poisoning attacks. 

• Applied Introduction to Cryptography (see also textbook. Presentations are outdated, should be improved.)

  • Encryption and pseudorandomness

  • Message authentication

  • Hash, digest and blockchain schemes

  • Shared key protocols

  • Public key cryptography: part I (key exchange), part II (encryption)

  • The TLS/SSL protocols and web-security

  • Public key infrastructure. See also my PKI tutorial. 

  • Human-centered cryptography
