1 ) Define Logging Levels?, - Logging Levels are categories used to, - classify the severity or importance, - of a log message generated by a system or application., - Security analysts use these levels, - to filter, prioritize, and focus on the most critical events,, - which is essential because modern networks generate millions, - of log entries per day.

2 ) Explain The Importance of Logging Levels:, - By setting the correct logging level, - in the system's configuration (an architecture decision),, - you control the volume and detail, - of data being ingested by your SIEM,, - ensuring that analysts aren't overwhelmed by low-priority noise.

3 ) Define the Structure of Logging Levels:, - The table of common logging levels,, - typically ordered from most severe (lowest numerical value), - to least severe (highest numerical value),, - is based on the Syslog standard , - ( used widely by Linux/Unix and network devices ).

4 ) List the common logging levels:, - Level 0:, - Emergency , - Level 1:, - Alert, - Level 2:, - Critical, - Level 3:, - Error, - Level 4:, - Warning, - Level 5:, - Notice, - Level 6:, - Informational, - Level 7:, - Debug

5 ) List and Define Logging Level 0:, - Level 0:, - Emergency, - The Emergency Level signifies, - the System is unusable., - A crisis event where a system, - has crashed or is entirely unstable., - Immediate action is required.

6 ) List and Define Logging Level 1:, - Level 1:, - Alert, - The Alert Level signifies, - that Action must be taken immediately., - Critical conditions that require immediate intervention,, - such as a major service failure, - or primary path down.

7 ) List and Define Logging Level 2:, - Level 2:, - Critical, - The Critical Level signifies, - Critical conditions., - A major failure has occurred,, - such as a critical application component failing, - or system instability.

8 ) List and Define Logging Level 3:, - Level 3:, - Error, - The Error Level signifies, - Error conditions., - Less severe than Critical,, - but these are failures that might still, - impact functionality and require fixing.

9 ) List and Define Logging Level 4:, - Level 4:, - Warning, - The Warning Level signifies, - Warning conditions., - Events that indicate , - a potential issue but are not yet errors,, - such as low disk space, - or a failed login attempt.

10 ) List and Define Logging Level 5:, - Level 5:, - Notice, - The Notice Level signifies, - normal but significant conditions., - Events that are generally routine, - but should be tracked,, - such as a scheduled reboot , - or successful connection by an administrator.

11 ) List and Define Logging Level 6:, - Level 6:, - Informational, - The Informational Level, - signifies Informational messages. , - Standard operational events,, - like a service starting or stopping,, - or routine system status updates.

12 ) List and Define Logging Level 7:, - Level 7:, - Debug, - The Debug Level signifies, - Debug-level messages., - Detailed information typically used, - only for troubleshooting and software development., - In production security operations,, - this is usually disabled due to extreme log volume.

13 ) Explain The Importance of the Security Analyst Role,, in regards to Triage and Prioritization:, - You configure your SIEM to only generate alerts, - for high-severity logs (0-3), - to reduce false positives and focus, - your limited time on true threats.

14 ) Explain The Importance of the Security Analyst Role,, in regards to Storage Management:, - Keeping logging levels high, - (e.g., at Debug/7) , - creates enormous log volume,, - rapidly filling expensive storage., - Configuring systems to send, - only Warning (4) or above helps manage this resource.
