1. Firewalls (e.g., Palo Alto, Fortinet)

Firewalls inspect and control traffic at the edge and inside the network using policy, application awareness, and threat prevention to keep untrusted traffic out and sensitive data in. Platforms like Palo Alto and Fortinet add rich visibility, intrusion prevention, and sandboxing that turn a simple gate into a smarter, adaptive filter.

Why It's Important

Firewalls enforce boundaries. They reduce attack surface, stop unauthorized access, and shape traffic flow so the network stays healthy and resilient when attackers come knocking.

How to Improve Firewalls (e.g., Palo Alto, Fortinet) Skills

1. Patch relentlessly: Keep firmware, threat signatures, and content updates current.

2. Tighten policy: Write least‑privilege, application‑aware rules. Remove stale, shadowed, and overly broad entries.

3. Segment: Use zones and VLANs to confine movement; apply inter‑zone policies that assume compromise.

4. Plug in threat intel: Enrich with curated feeds and dynamic block lists to catch emerging indicators fast.

5. Turn on advanced analysis: Sandboxing for unknown files and links; DNS and URL filtering with custom categories.

6. Log everything that matters: Forward to a SIEM; build alerts for high‑risk events and rule changes.

7. Test, then test again: Quarterly rule reviews and configuration audits. Validate with traffic simulation.

8. Plan for failure: Deploy high availability pairs and document failover runbooks. Test them.

9. Harden remote access: Strong crypto, MFA, device posture checks, and narrow access scopes for VPNs.

Use vendor best practices, but shape them to your environment. Precision beats bloat.
