GCP User Accessed Region

This alert occurs when Lacework detects a user has accessed a region for the first time.

Why this Alert is Important​

A region is a specific geographic location where Google has data centers that can be used to host your resources. Each region consists of one or more zones, isolated locations within the region designed to be independent and fault-tolerant.

A user accessing a region for the first time could indicate unauthorized access or a security breach. Monitoring such events can help you detect potential threats and take action before any damage is done.

Investigation​

Investigating signs of malicious activity when a user accesses a region for the first time in GCP can involve several steps, including:

  1. Track login activity and verify that each login attempt is legitimate. Any suspicious login attempts should be investigated further.
  2. Analyze access logs for any suspicious activity.
  3. Track resource usage, network traffic, and other metrics that can indicate unusual activity. For example, a user accessing an unusually high number of resources in a region could be a sign of malicious activity.
  4. Use threat intelligence feeds for information about known malicious actors and their tactics, techniques, and procedures.
  5. Conduct a risk assessment to help identify potential vulnerabilities and prioritize security measures.

Resolution​

To resolve unauthorized access to a region, you can take the following steps:

  1. Disable the access.
  2. Investigate the incident for the user's identity, the time and duration, and the activities performed during the access. Check if any resources have been compromised or any unauthorized changes have been made.
  3. Depending on the severity of the incident, you may need to take various corrective actions, such as resetting passwords, revoking access, or reinstalling compromised resources.
  4. To prevent such incidents in the future, consider improving your security measures, such as implementing multi-factor authentication, monitoring, and logging activities, and regularly reviewing and updating access controls and policies.
