Incident Types

When it comes to firewalls, incidents can vary. Understanding these types is step one in effective incident management. Let’s break down a few:

• Unauthorized Access: Unwelcome guests poking around? We swiftly move into lockdown mode.
• Denial of Service (DoS): Does suddenly seem like a blackout in service? Time to diagnose and defend.
• Malware Infiltration: Sneaky malware slipping through? We zap it out before it spreads.
• Configuration Errors: Mistakes happen. We ensure quick rectification to keep the network sanely configured.

Our Incident Response Plan

Alright, let’s talk action. Responding to incidents effectively hinges on an ironclad plan. Here’s how we do it:

1. Preparation:
   • Continuously monitor Fortinet firewalls.
   • Regular training for our team to stay ahead of threats.
2. Identification:
   • Recognize potential threats, anomalies, or unusual behavior.
   • Utilize Fortinet’s advanced logging features for early detection.
3. Containment:
   • Immediately isolate threats to prevent spreading.
   • Use network segmentation when necessary for added defense.
4. Eradication:
   • Find the root cause and eliminate it entirely.
   • Remove all malicious traces to ensure a clean slate.
5. Recovery:
   • Safely reinstate systems while maintaining vigilance.
   • Confirm systems are running without a hitch.
6. Review:
   • Reflect on incident handling for insights and improvements.
   • Amend any policies, if needed, based on the learnings.

Case Study

Now, let’s dive into a real-life scenario. Picture this – a busy Monday morning, you receive an alert. Anomalies detected. Here’s what happened:

Our Fortinet firewall flagged an unusual spike in outgoing network traffic. From zero to alert in minutes, we sprang into action.

1. Identification: Quick analysis of logs revealed unauthorized data being exfiltrated.
2. Containment: We immediately isolated the affected systems, blocking the action.
3. Eradication: Deep dive to find hidden malware that had slipped through an email. It was eradicated completely.
4. Recovery: Systems were brought back online securely, with added monitoring layers.
5. Review: We sat down with the team, analyzed the event, and added new rules for the firewall to enhance future detection.
