Perimeter Protection and Intrusion Detection
The module explores perimeter protection and intrusion detection, focusing on firewalls as critical network security components. It discusses various firewall architectures, such as packet-filtering and stateful inspection firewalls, as well as advanced techniques used in firewalls like next-generation firewalls (NGFWs). In addition, the importance of intrusion detection systems (IDS) and security information and event management (SIEM) systems for comprehensive security monitoring is emphasized.

What we have learnt
- Firewalls serve as controlled gateways inspecting network traffic to enforce security policies.
- Different types of firewalls offer varying levels of security and operational capabilities.
- Intrusion detection systems (IDS) are essential for monitoring and responding to suspicious activities that may bypass firewalls.
Key Concepts
- -- Firewall
- A network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
- -- Intrusion Detection System (IDS)
- A device or software application that monitors a network or systems for malicious activity or policy violations.
- -- NextGeneration Firewall (NGFW)
- Advanced firewalls that integrate multiple security functions, including deep packet inspection and intrusion prevention.
- -- Security Information and Event Management (SIEM)
- A software solution that aggregates and analyzes security data from across an organization to provide real-time visibility and alerts.
