Presentations: Lectures, Tutorials and Others

Cybersecurity Lectures:

• Internet Security Lectures (most updated to Fall'23)

  • Vulnerabilities, Malware and Cyber-security Ethics

  • ‘Knowledge is Power’: Reconnaissance and Scanning 

  • Firewalls - and a bit on IDS/IPS and Honeypots (aka, basic tools)

  • Web security attacks and defenses. Quite a lot yet only the tip of the iceberg!

  • DNS security attacks (mostly poisoning) and defenses (incl. DNSSEC). 

  • Internet inter-domain routing (BGP) security (5/24/24). See also old, powerpoint presentation which covers also some areas not yet covered in the new (Beamer) presentation.  

  • Denial of Service attacks and defenses. Quite comprehensive, I think; but it's such wide and dynamic area...

  • TCP/IP security (and few quick words QUIC too). Incl. fragmentation attacks (also applied to DNS), spoofing/SAV (incl. uRPF), TCP injections and more. 

  • 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 Presentations are outdated, should be improved.)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
