In the 21 Century, the CS0-004 certification became more and more recognized in the society because it represented the certain ability of examinees. However, in order to obtain CS0-004 certification, you have to spend a lot of time preparing for the CS0-004 Exam. Many people gave up because of all kinds of difficulties before the examination, and finally lost the opportunity to enhance their self-worth. As a thriving multinational company, we are always committed to solving this problem.
NEW QUESTION # 113
A security operations center analyst receives an alert from the security information and event management system. The analyst quickly reviews the alert and sees a workstation infected with malware. The analyst then uses the endpoint detection and response tool to isolate the workstation from the network.
Which of the following best describes the steps that occurred in this scenario?
Answer: A
Explanation:
The sequence is detection, analysis, and containment . First, the SIEM generates an alert indicating potentially malicious activity. This represents detection because the security monitoring infrastructure has identified a condition requiring investigation.
The analyst then reviews the alert and determines that the workstation is infected with malware. That validation and interpretation constitute analysis . Analysis establishes whether an alert represents a true incident, determines affected assets, and develops sufficient understanding to choose an appropriate response.
Finally, the analyst uses the EDR platform to isolate the workstation from the network. Isolation is a classic containment action because it prevents the infected endpoint from communicating with other systems, spreading malware, exfiltrating data, or maintaining command-and-control communications while the investigation continues.
Eradication has not yet occurred because the scenario does not indicate that the malware, persistence, compromised credentials, or root cause has been removed. Recovery also has not occurred because the system has not been restored to normal service.
NIST's current incident-response model explicitly emphasizes Detect, Respond, and Recover and includes containment and eradication within incident-response activities.

NEW QUESTION # 114
The Chief Information Officer (CIO) is requiring users to phase out a legacy system that no longer receives security updates because the system will be decommissioned soon.
Which of the following risk management strategies is the CIO using?
Answer: C
Explanation:
The CIO is implementing risk avoidance because the organization is eliminating the activity or technology that creates the risk. The legacy system no longer receives security updates, so continued operation would maintain exposure to vulnerabilities that may eventually become impossible to remediate. By phasing out and ultimately decommissioning the system, the organization removes that source of risk instead of continuing to operate it under additional controls.
NIST recognizes acceptance, avoidance, mitigation, sharing, and transfer as established risk-response approaches. Avoidance differs from mitigation because mitigation would retain the legacy system while implementing controls that reduce its likelihood or impact-for example, segmentation, strict access controls, application allowlisting, or enhanced monitoring.
Risk acceptance would involve deliberately continuing to operate the system after management acknowledges and approves the remaining exposure. Risk transference would shift some financial or operational consequences to another party, such as through insurance or contractual arrangements.
The phrase "phase out" is the decisive indicator. The organization intends to stop using the risk-producing technology entirely, making avoidance the most precise classification.

NEW QUESTION # 115
Based on recent alerts, a security analyst thinks a web application server was compromised. The analyst reviews the following server output:
Which of the following best describes what has occurred?
Answer: D
Explanation:
The web-service account www has an interactive tty2 session originating from an external IP address. A service account should not normally have an interactive remote login, indicating unauthorized access.
NEW QUESTION # 116
Which of the following network architectures would best implement a perimeter-less network topology?
Answer: A
Explanation:
Secure access service edge is specifically designed for environments in which users, devices, applications, and workloads are distributed beyond a traditional enterprise network perimeter. SASE integrates networking and security functions into a service-oriented architecture so policy enforcement can follow the user or workload rather than depend solely on traffic traversing a centralized corporate boundary.
This makes SASE particularly suitable for a perimeter-less topology , where employees may work remotely, applications may reside in multiple cloud providers, and services may be accessed directly over the internet.
Typical SASE implementations combine software-defined wide-area networking with cloud-delivered security controls such as secure web gateways, cloud access security brokerage, firewall-as-a-service, and Zero Trust-oriented access controls.
A hybrid cloud network connects private and public cloud resources but can still operate using conventional network boundaries. Cloud-native computing describes an application and infrastructure design approach based on cloud technologies such as containers, microservices, and automation; it does not inherently define perimeter-less access security. A content delivery network distributes content geographically for performance and availability and is not an enterprise access-security architecture.
The CS0-004 Security Operations objectives explicitly identify SASE, Zero Trust Network Architecture, and hybrid cloud as network architecture concepts analysts must understand.

NEW QUESTION # 117
Multiple users report unexpected mouse movements and terminal windows opening.
An analyst reviewing the network traffic logs observes the following:
Which of the following is the most likely reason for the reported symptoms?
Answer: C
Explanation:
The activity is consistent with Virtual Network Computing (VNC) remote-control sessions. VNC provides interactive graphical access to another computer, which can manifest to the local user as unexpected mouse movement, windows opening, applications launching, or terminal sessions appearing without direct user interaction.
The network evidence distinguishes VNC from the other possibilities. Nmap's official VNC detection documentation demonstrates VNC services operating on TCP port 5900 and provides NSE functionality for querying VNC protocol versions and supported security mechanisms. When traffic logs show connections consistent with VNC services and users simultaneously observe visible remote desktop activity, VNC is the strongest correlation.
An internally addressable source address establishes only where traffic originated; it does not explain interactive mouse and keyboard activity. A reverse tunnel can provide an attacker with connectivity through network restrictions, but the tunnel itself does not identify the remote-control protocol responsible for the graphical symptoms. RDP can also provide interactive remote access, but it uses a different protocol and service profile; the traffic evidence in the scenario aligns with VNC instead.
An analyst should therefore correlate endpoint symptoms with network protocol and port evidence , rather than diagnosing remote access solely from visible user-interface behavior.
