Study Notes

Network Security Fundamentals

Hash functions are used for digital signature and to reduce the size of the signature.
Hash functions provide pre-image resistance, second pre-image resistance, and collision resistance.
Intrusion detection systems (IDS) are used to monitor network traffic and detect potential attacks.
IDS can be network-based or host-based and use signature-based, anomaly-based, behavior-based, or heuristics-based detection methods.
Virtual Private Network (VPN) is used to securely transfer data across public networks, ensuring authenticity, integrity, access control, and confidentiality.
VPN can be LAN-to-LAN internetworking or remote access.
IPSec is a framework used to protect IP traffic with confidentiality, integrity, and authentication.
IPSec has two modes: transport mode and tunnel mode.
Bastion host, screened subnet, multi-homed firewall, software firewall, and hardware firewall are different types of firewalls used for network security.
Firewall technologies include packet filtering, circuit level gateway, application level gateway, and stateful multilayer inspection.
DNS is vulnerable to spoofing and amplification attacks, which can lead to DNS cache poisoning and re-binding attacks.
DNS cache poisoning and re-binding attacks can compromise network security and allow attackers to access internal networks.
