A zero-day vulnerability is actively exploited in a critical web server, but no vendor patch is available. What should be the FIRST step to manage this risk?
A. Shut down the server
B. Monitor for suspicious activity
C. Apply a virtual patch using a WAF
D. Perform regular backups and prepare IR plans
答案：C
解題說明：
According to CEH v13 Security Operations and Incident Response, zero-day vulnerabilities pose one of the highest operational risks because exploits exist before official remediation is available. When active exploitation is observed and no vendor patch exists, immediate compensating controls must be deployed.
The first and most effective action is implementing virtual patching, typically through a Web Application Firewall (WAF) or Intrusion Prevention System (IPS). CEH v13 defines virtual patching as a security measure that blocks exploitation attempts at the network or application layer without modifying the vulnerable software. This approach allows organizations to maintain service availability while reducing exposure.
Shutting down the server (Option A) may prevent exploitation but introduces unacceptable business disruption and is not recommended as a first response. Backups and incident response planning (Option C) are critical but do not actively prevent exploitation. Passive monitoring (Option D) allows attackers to continue exploiting the vulnerability unchecked.
CEH v13 emphasizes that virtual patching is the preferred first response for zero-day threats, especially when systems are mission-critical. It provides immediate risk reduction while allowing time for vendor patch development and controlled deployment.

Mar 1, 2016, 7:33:28 AM 10.240.250.23 - 54373 10.249.253.15 - 22 tcp_ip
A. Application is FTP and 10.240.250.23 is the client and 10.249.253.15 is the server.
B. SSH communications are encrypted; it's impossible to know who is the client or the server.
C. Application is SSH and 10.240.250.23 is the client and 10.249.253.15 is the server.
D. Application is SSH and 10.240.250.23 is the server and 10.249.253.15 is the client.
答案：C

Abel, a cloud architect, uses container technology to deploy applications/software including all its dependencies, such as libraries and configuration files, binaries, and other resources that run independently from other processes in the cloud environment. For the containerization of applications, he follows the five- tier container technology architecture. Currently. Abel is verifying and validating image contents, signing images, and sending them to the registries. Which of the following tiers of the container technology architecture Is Abel currently working in?
A. Tier-2: Testing and accreditation systems
B. Tier-1: Developer machines
C. Tier-3: Registries
D. Tier-4: Orchestrators
答案：A
解題說明：
The official management decision given by a senior agency official to authorize operation of an information system and to explicitly accept the risk to agency operations (including mission, functions, image, or reputation), agency assets, or individuals, based on the implementation of an agreed-upon set of security controls.
formal declaration by a designated accrediting authority (DAA) or principal accrediting authority (PAA) that an information system is approved to operate at an acceptable level of risk, based on the implementation of an approved set of technical, managerial, and procedural safeguards. See authorization to operate (ATO).
Rationale: The Risk Management Framework uses a new term to refer to this concept, and it is called authorization.
Identifies the information resources covered by an accreditation decision, as distinguished from separately accredited information resources that are interconnected or with which information is exchanged via messaging. Synonymous with Security Perimeter.
For the purposes of identifying the Protection Level for confidentiality of a system to be accredited, the system has a conceptual boundary that extends to all intended users of the system, both directly and indirectly connected, who receive output from the system. See authorization boundary. Rationale: The Risk Management Framework uses a new term to refer to the concept of accreditation, and it is called authorization. Extrapolating, the accreditation boundary would then be referred to as the authorization boundary.
問題 #415
An unauthorized individual enters a building following an employee through the employee entrance after the lunch rush. What type of breach has the individual just performed?
A. Announced
B. Tailgating
C. Reverse Social Engineering
D. Piggybacking
答案：B
解題說明：
Identifying operating systems, services, protocols and devices,
Collecting unencrypted information about usernames and passwords,
Capturing network traffic for further analysis
are passive network sniffing methods since with the help of them we only receive information and do not make any changes to the target network. When modifying and replaying the captured network traffic, we are already starting to make changes and actively interact with it.
問題 #416
Log monitoring tools performing behavioral analysis have alerted several suspicious logins on a Linux server occurring during non-business hours. After further examination of all login activities, it is noticed that none of the logins have occurred during typical work hours. A Linux administrator who is investigating this problem realizes the system time on the Linux server is wrong by more than twelve hours. What protocol used on Linux servers to synchronize the time has stopped working?
