Answer

Analyzing network flow logs for data exfiltration

Answer

Checking configuration management logs for resource changes

Question 2

A cloud security analyst is configuring a SIEM correlation rule to detect mass data exfiltration from an AWS S3 bucket. Which THREE log sources should be ingested to create an effective detection? (Choose three.)

Accepted Answer

CloudTrail data events for S3. CloudTrail data events for S3 capture object-level API operations such as GetObject, PutObject, and DeleteObject. By monitoring these events, a SIEM can detect anomalous patterns like a sudden spike in read requests from a single IP, which is a strong indicator of mass data exfiltration. This log source provides the granularity needed to identify the specific actions and actors involved in data access.

Question 8

An incident response playbook for a cloud environment includes containment steps. For a compromised IAM user in AWS, which action is least likely to be effective for containment?

Accepted Answer

Change the IAM user's password. Changing the IAM user's password does not invalidate existing authenticated sessions or tokens (such as temporary credentials from STS or access keys). An attacker who has already established a session or obtained access keys can continue to use them until they expire or are explicitly revoked. Therefore, password change alone is ineffective for immediate containment.

Answer

Disable the IAM user

Answer

Attach a DenyAll policy to the user

Answer

Disable the IAM user's access keys

Question 9

A security analyst notices a spike in failed login attempts from an IP address in a country where the company has no operations. Which SIEM correlation rule would be most effective in detecting this type of activity?

Accepted Answer

Mass S3 download – high volume of GetObject requests from a single IP. A mass S3 download rule detects a high volume of GetObject requests from a single IP, which aligns with the scenario of a spike in failed login attempts from a single IP. While the rule is designed for data exfiltration, it can be adapted to detect any anomalous high-volume activity from a single source, making it the most effective among the given options. Impossible travel (B) requires successful logins from distant locations, not failed attempts, and the other options address different threats.

Answer

Root account usage – alert when root user performs any action

Answer

Impossible travel – login from two geographically distant locations within minutes

Answer

New IAM admin user creation – detection of privileged role assignment

Question 10

Question 11

An organization is setting up a centralized logging solution across multiple accounts in their cloud environment. The security team requires that logs from all accounts be sent to a single security account, with lifecycle policies to transition logs to cheaper storage after 90 days. Which approach should be used?

Accepted Answer

Use the cloud provider's organizational structure and enable a single audit logging configuration that delivers logs to a central storage container in the management account.. For cross-account log aggregation, the cloud provider's organizational structure can be used to centrally manage audit logging. A single audit logging configuration can be enabled that delivers logs from all accounts to a central storage container in the management account. Lifecycle policies on that container can then manage transitions to lower-cost storage classes after 90 days.

Answer

Enable the cloud provider's native audit logging in each account and manually copy logs daily to the security account.

Answer

Create an audit log configuration in each account and export logs to a centralized monitoring service, then use cross-account log forwarding to a central storage container.

Answer

Use a serverless function to copy logs from each account's storage container to the central storage container.

Question 12

A security analyst is investigating a potential breach and needs to verify the integrity of audit logs stored in cloud storage. Which feature should the analyst rely on to confirm that logs have not been tampered with?

Accepted Answer

Log file integrity validation.
