What can Tier 1 SOC analysts do to avoid potential errors due to inaccuracies in reconstructing the investigation activities?

To avoid potential errors due to inaccuracies in reconstructing the investigation activities, Tier 1 SOC analysts can:

• Take good notes during the security alert investigations. Detailed note-taking is essential for accurately documenting the steps taken during an investigation. This ensures that all actions and observations are recorded in real-time, reducing the likelihood of missing or forgetting important details.

Using screen capture to record investigation actions can be helpful, but it may not always be practical or allowed due to privacy or security policies. Escalating to a Tier 2 analyst for verification is a step that might be taken in complex cases, but it’s not a primary method for avoiding errors in documentation. Providing all investigation details in the incident notification to the IR team is important, but it’s more about communication and collaboration than about ensuring accuracy in the reconstruction of investigation activities.
