Essential Tools for SOC Analysts
SIEM (Security Information and Event Management)
When I first tried using a SIEM, it felt like magic—alerts would pop up whenever something suspicious happened.
But here’s the truth: SIEMs are only as effective as the rules you configure. If you set up poor rules, you’ll get poor results.
For instance, I often use Wazuh, a well-known SIEM tool that works by using carefully set-up rules. It also lets you create custom rules to effectively find and respond to threats.
What is SIEM?
- A system that logs and analyzes events across your network.
- Alerts you to suspicious patterns, like failed logins or mass file deletions.
Popular SIEM Solutions:
- Splunk
- IBM QRadar
- Microsoft Sentinel
Pro Tip: SIEM alerts can sometimes be false positives. Learn to spot these and tweak rules to save time.
Log Management
Logs are like breadcrumbs—they show where things went wrong.
In one situation, I tracked malware activity back to a single entry in the proxy log.
Without log management, I would have had to search through thousands of files by hand.
Why It’s Important:
- Centralizes logs from different systems like firewalls, servers, and applications.
- Speeds up investigations.
EDR (Endpoint Detection and Response)
This tool is your best friend for investigating endpoint devices like laptops or servers.
Why You’ll Love It:
- Tracks File Changes: EDR solutions are designed to monitor file activities on endpoint devices.
This includes tracking modifications, deletions, and new file creations to identify potential threats. - Monitors Network Connections: It keeps a close watch on the network activities of endpoint devices.
By analyzing incoming and outgoing connections, it can detect unusual patterns indicating an attack. - Analyze Running Processes: EDR tools examine processes running on endpoints, identifying malicious or unauthorized processes.
- Device Isolation for Malware Containment: When a threat is detected, EDR enables the isolation of infected devices.
This helps stop malware from spreading across your network, protecting other systems.
The Role of EDR in SOC Fundamentals
EDR is an important part of SOC Basics (Security Operations Center Fundamentals). It helps detect and respond to security threats on individual devices.
- Endpoint Monitoring: EDR solutions are a key part of a SOC. They closely monitor activities on devices to catch any harmful actions that might otherwise be missed.
