Professional Security Operations EngineerPreview

You are responsible for identifying suspicious activity and security events at your organization. You have been asked to search in Google Security Operations (SecOps) for network traffic associated with an active HTTP backdoor that runs on TCP port 5555. You want to use the most effective approach to identify traffic originating from the server that is running the backdoor. What should you do?

You are an incident responder at your organization using Google Security Operations (SecOps) for monitonng and investigation. You discover that a critical production server, which handles financial transactions, shows signs of unauthorized file changes and network scanning from a suspicious IP address. You suspect that persistence mechanisms may have been installed. You need to use Google SecOps to immediately contain the threat while ensuring that forensic data remains available for investigation. What should you do first?

Your organization's Google Security Operations (SecOps) tenant is ingesting a vendor's firewall logs in its default JSON format using the Google-provided parser for that log. The vendor recently released a patch that introduces a new field and renames an existing field in the logs. The parser does not recognize these two fields and they remain available only in the raw logs, while the rest of the log is parsed normally. You need to resolve this logging issue as soon as possible while minimizing the overall change management impact. What should you do?

The logs are currently only available on-premises and are stored in a standalone network-attached storage (NAS) located in four different regions. You need to ingest the logs into Google SecOps and tag each NAS as a specific log source to avoid IP address aliasing. What should you do?

Your company uses Security Command Center (SCC) and Google Security Operations (SecOps). Last week, an attacker attempted to establish persistence by generating a key for an unused service account. You need to confirm that you are receiving alerts when keys are created for unused service accounts and that newly created keys are automatically deleted. You want to minimize the amount of manual effort required. What should you do?

Your organization has mission-critical production Compute Engine VMS that you monitor daily. While performing a UDM search in Google Security Operations (SecOps), you discover several outbound network connections from one of the production VMs to an unfamiliar external IP address occurring over the last 48 hours. You need to use Google SecOps to quickly gather more context and assess the reputation of the external IP address. What should you do?

You are a platform engineer at an organization that is migrating from a third-party SIEM product to Google Security Operations (SecOps).

You have discovered that a server that hosts an internal web application has been accidentally exposed to the internet for 48 hours. Logging is enabled on the server. You want to use Google Security Operations (SecOps) to run a UDM search against the server logs to identify whether there have been any successful exploitations against it. What event field search should you use?

You are the SOC manager at a large enterprise that uses Google Security Operations (SecOps). You need to create a report that shows the Return on Investment (ROI) attributed to analyst activities in Google SecOps SOAR for the previous month. The report should include the time saved and efficiency gains from using SOAR's features.

You need to ensure that the external IP address is flagged if it has a documented relationship to other APT41 indicators within the Fusion Feed. How should you configure this YARA-L rule?
