Cheat Sheet
- Understanding Firewall Types -
Firewalls come in various flavors - packet”filtering, stateful, and next”generation (NGFW) - each adding layers of inspection from basic IP/port checks to deep packet examination. For example, Cisco ASA offers stateful packet inspection while Palo Alto's NGFW integrates application awareness and threat intelligence (source: Cisco, SANS Institute). A handy mnemonic is "P-S-N" (Packet, Stateful, Next”gen) to recall the progression of capabilities.
- Stateful vs. Stateless Packet Filtering -
Stateless firewalls evaluate each packet in isolation, whereas stateful firewalls maintain a connection table tracking TCP handshakes (SYN, SYN”ACK, ACK) to verify session legitimacy (source: NIST SP 800-41). Think "Stateful Keeps a Story, Stateless Forgets History" to remember their fundamental difference. In practice, stateful inspection reduces false positives by ensuring only valid return traffic passes.
- Application Firewall (WAF) Essentials -
Web application firewalls inspect Layer 7 traffic, defending against OWASP Top 10 threats like SQL injection and XSS by parsing HTTP/HTTPS payloads (source: OWASP). A real”world example is ModSecurity, which uses rule sets to match malicious patterns - "SQLi stops at WAF's gate" is a simple memory aid. WAFs often sit in front of web servers in a reverse”proxy setup to sanitize input before it reaches applications.
- Rule Processing Order & Default Deny -
Firewalls evaluate rules sequentially - first match wins - so placing specific allow statements before broader denies is critical (source: SANS). Always implement an implicit "deny all" at the end of your rule set; a common ordering mnemonic is "Allow, Then Deny, Always Log" (ADL). This structure ensures you explicitly permit known traffic and block everything else by default.
- Host-Based Software Firewall Best Practices -
Software firewalls on individual hosts (e.g., iptables on Linux or Windows Defender Firewall) enable per”process rule control and granular policy enforcement (source: Microsoft Docs, Linux Foundation). Adhere to the principle of least privilege: allow only the minimum ports and applications required for each server's role. A quick tip is "Lock Down Every App" to remind administrators to review and tighten host rules regularly.
