NEW QUESTION # 128
An organization was breached via a web application attack to a database in which user inputs were not validated. This can BEST be described as which type of attack?

  • A. Buffer overflow
  • B. X-Path
  • C. Broken access control
  • D. Infection

Answer: C

Explanation:
The described scenario indicates aInjection (i)attack, where the attacker exploitsinsufficient input validation in a web application to manipulate queries. This type of attack falls under the category ofBroken Access Controlbecause:
* Improper Input Handling:The application fails to properly sanitize or validate user inputs, allowing malicious commands to execute.
* Direct Database Manipulation:Attackers can bypass normal authentication or gain elevated access by injecting code.
* OWASP Top Ten 2021:ListsBroken Access Controlas a critical risk, often leading to data breaches when input validation is weak.
Other options analysis:
* B. Infection:Typically involves malware, which is not relevant here.
* C. Buffer overflow:Involves memory management errors, not manipulation.
* D. X-Path:Involves XML query manipulation, not databases.
CCOA Official Review Manual, 1st Edition References:
* Chapter 4: Web Application Security:Discusses Injection as a common form of broken access control.

Answer:

Explanation:
Step 1: Define the Problem and Objective
Objective:
* Identify thefile containing the rulesetforEternalBlue connections.
* Include thefile extensionin the response.
Context:
* The organization is experiencingfalse positive alertsfor theEternalBlue vulnerability.
* The rulesets are located at:
/home/administrator/hids/ruleset/rules
* We need to find the specific file associated withEternalBlue.
Step 2: Prepare for Access
2.1: SIEM Access Details:
* URL:
https://10.10.55.2
* Username:
ccoatest@isaca.org
* Password:
Security-Analyst!
* Ensure your machine has access to the SIEM system via HTTPS.

3.1: Connect via SSH (if needed)
* Open a terminal and connect:
ssh administrator@10.10.55.2
* Password:
Security-Analyst!
* If prompted about SSH key verification, typeyesto continue.
Step 4: Locate the Ruleset File
4.1: Navigate to the Ruleset Directory
* Change to the ruleset directory:
cd /home/administrator/hids/ruleset/rules
ls -l
* You should see a list of files with names indicating their purpose.
4.2: Search for EternalBlue Ruleset
* Use grep to locate the EternalBlue rule:
grep -irl "eternalblue" *
* Explanation:
* grep -i: Case-insensitive search.
* -r: Recursive search within the directory.
* -l: Only print file names with matches.
* "eternalblue": The keyword to search.
* *: All files in the current directory.
Expected Output:
exploit_eternalblue.rules
* Filename:
exploit_eternalblue.rules
* The file extension is .rules, typical for intrusion detection system (IDS) rule files.
Step 5: Verify the Content of the Ruleset File
5.1: Open and Inspect the File
* Use less to view the file contents:
less exploit_eternalblue.rules
* Check for rule patterns like:
alert tcp $EXTERNAL_NET any -> $HOME_NET 445 (msg:"EternalBlue SMB Exploit"; ...)
* Use the search within less:
/eternalblue
* Purpose:Verify that the file indeed contains the rules related to EternalBlue.
Step 6: Document Your Findings
* Ruleset File for EternalBlue:
exploit_eternalblue.rules
* File Path:
/home/administrator/hids/ruleset/rules/exploit_eternalblue.rules
* Reasoning:This file specifically mentions EternalBlue and contains the rules associated with detecting such attacks.
Step 7: Recommendation
Mitigation for False Positives:
* Update the Ruleset:
* Modify the file to reduce false positives by refining the rule conditions.
* Update Signatures:
* Check for updated rulesets from reliable threat intelligence sources.
* Whitelist Known Safe IPs:
* Add exceptions for legitimate internal traffic that triggers the false positives.
* Implement Tuning:
* Adjust the SIEM correlation rules to decrease alert noise.
Final Verification:
* Restart the IDS service after modifying rules to ensure changes take effect:
sudo systemctl restart hids
* Check the status:
sudo systemctl status hids
Final Answer:
* Ruleset File Name:
exploit_eternalblue.rules

  • D. Least privilege

Answer: A

Explanation:
The cybersecurity objective ofintegrityensures that data isaccurate, complete, and unaltered. The most direct method to support integrity is the use ofdigital signaturesbecause:
* Tamper Detection:A digital signature provides a way to verify that data has not been altered after signing.
* Authentication and Integrity:Combines cryptographic hashing and public key encryption to validate both the origin and the integrity of data.
* Non-Repudiation:Ensures that the sender cannot deny having sent the message.
* Use Case:Digital signatures are commonly used in secure email, software distribution, and document verification.
Other options analysis:
* A. Data backups:Primarily supports availability, not integrity.
* C. Least privilege:Supports confidentiality by limiting access.
* D. Encryption:Primarily supports confidentiality by protecting data from unauthorized access.
CCOA Official Review Manual, 1st Edition References:
* Chapter 5: Data Integrity Mechanisms:Discusses the role of digital signatures in preserving data integrity.
