Cisco Conducting Forensic Analysis & Incident Response Using Cisco Technologies for CyberOps Sample Questions (Q115-Q120):

NEW QUESTION # 115
A security team detected an above-average amount of inbound tcp/135 connection attempts from unidentified senders. The security team is responding based on their incident response playbook. Which two elements are part of the eradication phase for this incident? (Choose two.)

Answer: A,D

Explanation:
The eradication phase in incident response involveseliminating the root cause of the incidentand strengthening defenses to prevent reoccurrence. In this case:
* Intrusion Prevention System (D): Adding new rules to the IPS to detect and block malicious activity on TCP/135 is a direct eradication step to remove the threat's entry point and prevent future attacks.
* Centralized User Management (C): Hardening user accounts, removing unnecessary permissions, and applying tighter authentication/authorization measures helps eliminate the possibility that threat actors could exploit weak or mismanaged accounts to continue accessing the system.
Althoughanti-malware software (A)andenterprise block listing (E)are valuable, themost direct eradication stepshere specifically involve managing network access (via IPS) and strengthening user controls (via centralized user management), especially when TCP/135 (MSRPC endpoint mapper) can be used to enumerate services and potentially access vulnerable endpoints remotely.
This aligns with best practices outlined in incident response frameworks (such as the NIST SP 800-61 and referenced resources), which emphasizeclosing the exploited entry points(in this case, TCP/135) and removing any lingering access pointsthrough user management and network control enhancements.

NEW QUESTION # 116
Refer to the exhibit. A security engineer is conducting a security test and receives the following response from a SaaS application. Which mitigation should the engineer recommend?
POST /product/stock HTTP/1.1
Content-Type: application/x-www-form-urlencoded
productId=3 & storeId=1|whoami
HTTP/1.1 200 OK
Content-Type: text/plain; charset=utf-8
peter-QS7t9i

Answer: C

Explanation:
The pipe character in storeId=1|whoami causes the application to pass attacker-controlled input to a shell. The response contains the operating-system account name, demonstrating successful OS command injection. The strongest mitigation is to remove the application's direct shell dependency and use a safe language API or library for the required operation. If an OS command is unavoidable, the application must use fixed commands, structured arguments, strict allowlisting, least privilege, and context-appropriate escaping; filtering only one metacharacter is inadequate. Registered redirect URIs mitigate OAuth redirection abuse, not command injection. Restricting input to HTML does not make shell execution safe, and a template engine addresses rendering concerns. This maps to CBRFIR Incident Response Techniques objective 3.3, which covers identifying attack vectors and recommending mitigation. OWASP likewise identifies avoiding direct OS-command calls as the primary defense. OWASP OS Command Injection Defense


NEW QUESTION # 117
Refer to the exhibit.

A web hosting company analyst is analyzing the latest traffic because there was a 20% spike in server CPU usage recently. After correlating the logs, the problem seems to be related to the bad actor activities. Which attack vector is used and what mitigation can the analyst suggest?

Answer: A

Explanation:
Comprehensive and Detailed Explanation:
The log entries show repeated SSH login attempts for various invalid usernames (e.g., admin, phoenix, rainbow, test, user, etc.) from different source ports. These are clear signs of a brute-force attack-an automated process trying multiple usernames and passwords in hopes of gaining access.
Mitigating such attacks includes:
Implementing account lockout policies (e.g., locking an account after several failed login attempts).
Enabling Multi-Factor Authentication (MFA) to ensure that password guessing alone is insufficient for account access.
Therefore, the correct answer is:
D). Brute-force attack; implement account lockout policies and roll out MFA.


NEW QUESTION # 118
What are YARA rules based upon?

Answer: C


NEW QUESTION # 119
During a routine security audit, an organization's security team detects an unusual spike in network traffic originating from one of their internal servers. Upon further investigation, the team discovered that the server was communicating with an external IP address known for hosting malicious content. The security team suspects that the server may have been compromised. As the incident response process begins, which two actions should be taken during the initial assessment phase of this incident? (Choose two.)

Answer: A,B

Explanation:
During the initial phase of incident response, the two key actions are:
* Disconnecting the server (B) to contain the threat and prevent lateral movement or further exfiltration.
* Reviewing network logs (E) to understand the timeline and scope of the attack.
These are emphasized in the containment and detection stages of the incident response lifecycle outlined in NIST 800-61 and covered in the Cisco CyberOps training.
