Network Security
Requirements: FORMAL REQUIREMENTS: course of Local Area Networks.
Description:
Lecture:
- Network security: aspects, categories, definitions, goals, policies
- ISO OSI; security models (DiD, MLS)
- Cryptography: definitions; symmetric: substitution, transposition, block ciphers: modes, DES, 3DES, IDEA, AES), asymmetric: public/private key, RSA, ElGamal; Diffie-Helman key exchange algorithm; digital signature: CA; user authentication algorithms
- VPNs: L2:L2TP, L3:IPSec, L4:SSL/TLS
- Network attacks: phases: reconnaisance, exploit, propagation;
- Types: reconnaissance, DoS, protocols/systems discrepancies/weakness
- Viruses, worms, botnets
- IDS/IPS systems
- Routing security
- Software bugs: buffer overflow attacks
Labs:
- Network devices and their security functions
- Stateless and statefull firewall (sessions)
- Junos
- Routing instances, security zones, interfaces
- Security policies, local traffic
- Network attacks (reconnaissance, DoS, protocol discrepancies)
