Detailed content:

1. Basics of Information Security

  • Security architecture and infrastructure; security goals (confidentiality, integrity, availability, and authenticity); threats/vulnerabilities/attacks; risk management

2. Cryptographic Building Blocks

  • Symmetric crypto: ciphers (stream, block), hash functions, message authentication codes, pseudorandom functions
  • Public key crypto: public key encryption, digital signatures, key agreement

3. Network Security Protocols & Standards

  • Overview of networking and PKI
  • Transport Layer Security (TLS) protocol
  • Overview: SSH, IPsec, Wireless (Tool: Wireshark)

4. Offensive and defensive network security

  • Offensive: Pen-tester/attack sequence: reconnaissance; gaining access; maintaining access; denial of service attacks (Tool: nmap)
  • Defensive: Firewalls and intrusion detection

5. Access Control & Authentication; Web Application Security

  • Access control: discretionary/mandatory/role-based; phases
  • Authentication: something you know/have/are/somewhere you are
  • Web security: cookies, SQL injection
  • Supplemental material: Passwords

This workshop is part of the CryptoWorks21 program at the University of Waterloo, but is open to graduate students, post-docs, and industry researchers across Canada.
