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:

  1. 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.
  2. 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.
  3. Analyze Running Processes: EDR tools examine processes running on endpoints, identifying malicious or unauthorized processes.
  4. 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.
  • Incident Response: EDR tools help SOC teams respond quickly, stopping threats and reducing the damage caused by security breaches.

Synonyms for “SOC Fundamentals” in Context

  • Security Operations Center Essentials: EDR tools are a key part of these essentials, enabling effective monitoring and response.
  • SOC Basics: Understanding tools like EDR is foundational in mastering SOC basics.

Integrating EDR into SOC Fundamentals improves your skills in protecting endpoint devices and keeping the network secure.

Avoiding Common SOC Mistakes: A Guide to SOC Fundamentals

Understanding SOC Fundamentals is key to avoiding costly errors in managing security operations centers. Below are some common mistakes and tips to overcome them effectively:

1. Over-reliance on VirusTotal

While VirusTotal is a powerful tool, over-reliance on it can be a mistake.
Not all malware is detected by VirusTotal.
Always corroborate findings with other threat intelligence tools and malware analysis fundamentals to ensure comprehensive detection.

2. Hasty Sandbox Analysis

Malware doesn’t always reveal its true behavior immediately.
If sandbox analysis is done too quickly, you might miss key indicators of compromise.
To master threat detection principles, allow malware sufficient time to execute fully in a controlled environment.

3. Incomplete Log Analysis

Looking only at flagged devices can leave you blind to related threats.
Logs from associated systems often reveal important clues about lateral movement or coordinated attacks.
This is a basic practice in log analysis methodologies, which emphasize cross-system examination for deeper insights.

4. Ignoring Context

Alerts can seem minor when viewed in isolation.
However, every alert could be part of a larger, coordinated attack.
Understanding the context of alerts in SOC operations is essential to connect the dots and mitigate larger threats.

Frequently Asked Questions (FAQs)

1. When you close an alert, which channel can you access it from?

Once an alert is closed, it is stored in the “Closed Cases” channel of your SOC system.
This feature of incident management frameworks provides a historical reference for investigations.

2. What source IP address entered the URL ‘https://github.com/apache/flink/compare‘?

To identify the source IP address:

  1. Access your Log Management system.
  2. Look for log entries associated with the URL.
  3. Note the corresponding source IP.
    This is a fundamental step in network traffic analysis basics.

3. What type of log has a destination port number of 52567 and a source IP address of 8.8.8.8?

Logs with this information are typically firewall logs or network traffic logs.
These logs capture communication details between source and destination, a key focus of firewall log fundamentals.

4. What is the hostname of the device where the “nmap” file with a hash value of “83e0cfc95de1153d405e839e53d408f5” is executed?

Use an EDR tool to search for the hash value across hosts.
The endpoint detection principles of the tool will identify the hostname associated with the file execution.

5. A “Ps1.hta” file was executed on a device with the hostname “Roberto.” What is the complete CMD command?

To find the full CMD command:

  1. Open the Process List in your EDR solution.
  2. Search for “Ps1.hta” on the device “Roberto.”
  3. Review the logs for the complete CMD command.
    This process aligns with threat analysis strategies for process monitoring.

6. What is the data source of the “e1def6e8ab4b5bcb650037df234e2973” hash on the Threat Intel page?

Navigate to the Threat Intelligence Feed page and locate the hash.
The data source may be malware analysis, sandbox reports, or other feeds.
This is a practical example of threat intelligence basics.

7. Which type of SOC team does not have its facility and often works remotely in different locations?
