✍️ Sample CSX Questions & Answers
1. An investigator is analyzing Windows Event Logs and finds Event ID 4625. What does this indicate?
Windows Event ID 4625 logs a failed account logon attempt, including the account name, failure reason, and source network address.
2. Certificate Transparency (CT) logs are useful for reconnaissance because they:
CT logs require CAs to publicly log every issued certificate, enabling attackers and defenders alike to discover subdomains and infrastructure that organizations may not have intended to expose.
3. Which type of audience requires the most technical detail in a cybersecurity report?
The security operations team needs full technical detail including payloads, log excerpts, and tool output to investigate and remediate findings.
4. Which backup rotation scheme ensures that backups are retained across daily, weekly, and monthly intervals using a minimal number of media sets?
The Grandfather-Father-Son (GFS) scheme uses daily (Son), weekly (Father), and monthly (Grandfather) backup sets to balance retention coverage with media efficiency.
5. In threat modeling, what is the purpose of decomposing an application?
Application decomposition in threat modeling breaks down the system into components, data flows, and trust boundaries to systematically identify where threats could arise.
6. What is a correlation rule in a SIEM system?
Correlation rules define conditions that, when matched across multiple log events, trigger an alert indicating a potential security threat.
