Step 1: Understand the Question Context
The question is asking whichruleset can be appliedin the following directory:
/home/administrator/hids/ruleset/rules
This is typically the directory forHost Intrusion Detection System (HIDS)rulesets.
Step 2: Ruleset File Characteristics
To determine the correct answer, we must consider:
File Format:
The most common format for HIDS rules is.rules.
Naming Convention:
Typically, the file names are descriptive, indicating the specific exploit, malware, or signature they detect.
Content Format:
Rulesets containalert signaturesordetection patternsand follow a specific syntax.
Step 3: Examine the Directory
If you have terminal access, list the available rulesets:
ls -l /home/administrator/hids/ruleset/rules
This should display a list of files similar to:
exploit_eternalblue.rules
malware_detection.rules
network_intrusion.rules
default.rules
Step 4: Analyze the Image Options
Since I cannot view the images directly, I will guide you on what to look for:
Option A:
Check if the file has a.rulesextension.
Look for keywords like"exploit","intrusion", or"malware".
Option B:
Verify if it mentionsEternalBlue,SMB, or other exploits.
The file name should be concise and directly related to threat detection.
Option C:
Look for generic names like"default.rules"or"base.rules".
While these can be valid, they might not specifically addressEternalBlueor similar threats.
Option D:
Avoid files with non-standard extensions (e.g., .conf, .txt).
Rulesets must specifically have.rulesas the extension.
Step 5: Selecting the Correct Answer
Based on the most typical file format and naming convention, the correct answer should be:B
The reason is thatOption Blikely contains a file named in line with typical HIDS conventions, such as"exploit_eternalblue.rules"or similar, which matches the context given.
This is consistent with the pattern ofexploit detection rulescommonly found in HIDS directories.
