How to Do it Yourself: Collect and Store Detailed Logs

Enhance Your Security Monitoring with Effective Log Collection and Storage

Gathering and securely storing detailed logs of system activities is crucial for monitoring and responding to security incidents. This guide will walk you through collecting and storing logs effectively, aligning with CIS Control 6.5 (Maintenance, Monitoring, and Analysis of Audit Logs).

Step 1: Choose a Logging Solution

Select a tool to collect and store logs, such as Microsoft 365 tools like Azure Monitor or Microsoft Sentinel, or third-party solutions like Splunk, ELK Stack (Elasticsearch, Logstash, Kibana), or LogRhythm.

Step 2: Configure Log Collection

Set up your logging solution to collect relevant data. Ensure logging is enabled for all critical systems and applications and define the sources from which logs will be collected, such as servers, network devices, and applications.

Step 3: Secure Log Storage

Ensure that collected logs are stored securely. Store logs in a centralized, secure location and encrypt them both in transit and at rest to protect them from unauthorized access.

Step 4: Regularly Review Logs

Analyze logs to detect suspicious activity and potential security incidents. Configure your logging solution to send alerts for specific events or anomalies and schedule regular log reviews to identify and investigate unusual activities.

Step 5: Retain Logs for Compliance

Ensure logs are retained according to regulatory and business requirements. Define and implement log retention policies based on regulatory and business needs and regularly audit log retention practices to ensure compliance with policies.

Why Log Collection and Storage Matter

Collecting and securely storing logs help you monitor system activities, detect security incidents, and comply with regulatory requirements. By implementing effective log management, you can quickly identify and respond to potential threats, minimizing the impact of security incidents on your business.

This step aligns with CIS Control 6.5: Maintenance, Monitoring, and Analysis of Audit Logs, which focuses on ensuring logs are collected, stored, and analyzed to detect and respond to security incidents.

By following these steps, you can effectively collect and store detailed logs, enhancing your ability to monitor and respond to security incidents. Stay tuned for more tips on managing your business's cybersecurity risk effectively.
