NEW QUESTION # 10
Which of the following should be configured in a WAF to mitigate an RCE attack?
Answer: C
Explanation:
Remote Code Execution (RCE) attacks often attempt to execute operating system commands through user-supplied input. A WAF can mitigate these attacks by using rules that detect and block malicious command patterns and payloads before they reach the application. This provides protection at the web application layer against command execution attempts.
NEW QUESTION # 11
A new policy prohibits external access to database servers. A recent external port scan identified the following open Transmission Control Protocol (TCP) ports:
- 21
- 25
- 68
- 80
- 389
- 443
- 587
- 1514
- 3306
- 3389
- 8080
Which of the ports must be closed to be compliant with the new policy? (Choose two.)
Answer: A,C
Explanation:
Port 3306 is the default port used by MySQL database servers. Allowing external access to this port directly exposes the database service, which violates a policy that prohibits external access to database servers.
Port 3389 is used by Remote Desktop Protocol (RDP). External access through RDP allows direct administrative or user access to the server hosting the database, which effectively bypasses the restriction against external access to database servers and therefore must also be closed to comply with the policy.
NEW QUESTION # 12
There is an alert coming from the security information and event management system.
Which of the following is the first task an analyst should complete?
Answer: D
Explanation:
A SIEM alert is an indication requiring validation; it is not automatically a confirmed security incident. The analyst must therefore begin with triage . Triage establishes whether the activity is legitimate or malicious, determines the affected systems or accounts, evaluates severity and business impact, and establishes the appropriate investigative and escalation path.
Typical triage activities include reviewing the underlying events, checking source and destination information, identifying affected assets, correlating supporting telemetry, evaluating detection confidence, examining threat intelligence, and determining whether the alert represents a true positive. Only after this assessment can the incident be assigned an appropriate priority and routed to the correct responders.
Contacting an incident coordinator before establishing whether the alert represents meaningful risk may create unnecessary escalation. Recovery activities occur substantially later, after detection, analysis, containment, and eradication activities have established what happened and controlled the threat. Escalating directly to the help desk is similarly premature and may be inappropriate for a security event.
NIST's current incident-response model places detection and analysis before response and recovery actions and emphasizes determining event characteristics so appropriate response actions can follow.

NEW QUESTION # 13
An incident response team identifies a malicious uniform resource locator (URL) associated with a required business process and performs the following activities:
- Access to the URL has been restricted only to the necessary users
through firewall rules and Cloud Security Group rules.
- Additional monitoring has been enabled for traffic related to that
site and the allowed users.
- All application servers that need to access that site have been
patched with the latest security and software updates.
- Application owners have been notified of the severity and need to
remediate this reported issue.
Which of the following best describes the overall mitigation the security team is performing?
Answer: D
Explanation:
The malicious URL cannot be completely blocked because it supports a required business process, so the team is applying alternative safeguards-restricted access, monitoring, patching, and notifications-to reduce the risk.
NEW QUESTION # 14
The security team reviews a web server for XSS and runs the following Nmap scan:
Which of the following most accurately describes the result of the scan?
Answer: B
Explanation:
The Nmap http-unsafe-output-escaping script is used to detect whether a web application returns potentially dangerous characters without proper output encoding. The scan result identifies the vulnerable parameter (id) and shows that the characters > and " were reflected unfiltered in the response. This indicates a potential cross-site scripting (XSS) vulnerability due to improper output escaping.
