A company published software that had a security vulnerability, and an attacker used the vulnerability to steal critical information from the environment. The issue was reported by the security team, and the administrator was instructed to run shift-left security tests before publishing the software. Which component of the software development pipeline must be recommended to run the tests?
正解：C
解説：
In the context of theCisco SDSI v1.0blueprint, "shifting left" refers to the practice of integrating security testing as early as possible in the Software Development Life Cycle (SDLC). The most effective component of the pipeline for running these early tests isSource Code Management (SCM). By integrating security tools directly into the SCM system (such as GitHub, GitLab, or Bitbucket), developers can identify vulnerabilities while the code is still being written or during the initial commit phase.
Techniques such as Static Application Security Testing (SAST) and secret scanning are typically triggered at the SCM level through pull requests or commit hooks. This allows the security team to identify flawed logic or hardcoded credentials before the code is ever compiled or moved to the build stage. WhileContinuous Deployment(Option A) handles the final release of the software, it is too late in the pipeline for a "shift-left" approach to be most effective.Software Bill of Materials (SBOM) analysis(Option C) is a specific task focused on dependency management, andCloud Security Posture Management (CSPM)(Option B) focuses on the runtime environment rather than the application code itself. Utilizing SCM as the primary checkpoint ensures that security becomes a foundational part of the development process, reducing the risk of vulnerable software reaching production environments.

A bank experienced challenges with compromised endpoints gaining access to the internal network. To enhance security, the bank wants to ensure that all endpoints are scanned for compliance checks before being allowed to access the network. Which action achieves the level of security and control?
正解：B
解説：
In high-security environments like banking, simply verifying a user's identity is insufficient; the "health" or security state of the device must also be validated.Posture validation, implemented throughCisco Identity Services Engine (ISE), is the specific architectural process used to ensure an endpoint meets the organization's security requirements-such as having an active antivirus, the latest OS patches, or disk encryption enabled-before it is granted access to the internal network.
When an endpoint connects, Cisco ISE triggers a posture check (often via the Cisco Secure Client agent). If the device is found to be non-compliant (e.g., outdated signatures), ISE can move the endpoint into a restricted quarantineVLAN where it can only access remediation servers to update its software. Only after a successful re-scan shows the device is compliant is the network access policy updated to allow full internal connectivity.
This effectively prevents compromised or "dirty" endpoints from spreading threats laterally across the bank's network. WhileMFA(Option A) secures the user's identity andTrustSec(Option B) provides segmentation, only Posture validation addresses the technical compliance of the endpoint hardware and software itself.Data Loss Prevention(Option C) is focused on data transit rather than initial network admission control.

Employees in a healthcare organization could not access their devices when they returned to work after the weekend. The security team discovered that a threat actor had encrypted the devices. Which security solution would mitigate the risk in future?
正解：A
解説：
In the scenario described, the healthcare organization fell victim to aransomware attack, where devices were encrypted to extort the organization. To mitigate such risks in the future,Endpoint Detection and Response (EDR)is the essential architectural component. According to the Cisco SDSI Secure Infrastructure domain, protecting endpoints requires more than just traditional antivirus; it necessitates a solution that provides deep visibility into file behavior and process execution.
A robust EDR solution, such asCisco Secure Endpoint, continuously monitors all activity on the device.
When ransomware attempts to initiate its encryption process, the EDR can detect the malicious behavioral pattern in real-time. It can then take automated actions, such as isolating the infected host from the network and "stopping" the encryption process before it spreads. Furthermore, Cisco's EDR providesretrospective security, allowing administrators to see how the malware arrived and which other devices it touched. While Option A (Password Policies) helps prevent credential theft and Option C (DLP) prevents data theft, they do not stop the technical process of disk encryption. Only EDR provides the necessary detection and automated response capabilities to handle modern file-less and polymorphic malware threats effectively. This aligns with the Cisco SAFE goal of securing the endpoint layer against advanced persistent threats (APTs) and ransomware variants.

質問 # 41
A manufacturing company recently experienced a network-down scenario due to malware spread on the management network. The company wants to implement a solution to detect and mitigate a similar threat in the future and protect the overall network. Which solution meets the requirements?
正解：B
解説：
The spread of malware across a sensitive segment like themanagement networkhighlights a failure in host- level security and internal visibility. To detect and mitigate the spread of such threats and protect the overall network,Endpoint Detection and Response (EDR)is the most effective choice among the options. In the Cisco security ecosystem, the endpoint is often the last line of defense and the most critical source of telemetry for malware incidents.
By deploying an EDR solution likeCisco Secure Endpoint, the manufacturing company gains the ability to identify the "patient zero" of the infection. EDR uses advanced features likeDevice TraversalandLateral Movementdetection to see how malware moves from one machine to another over the management network.
Once detected, the security team can use the EDR platform to initiate a "host isolation" command, effectively cutting off the infected device's communication with the rest of the network without physically unplugging it.
WhileEncrypted Threat Analytics (ETA)(Option C) is a powerful network-based feature for detecting malware in encrypted traffic without decryption, EDR provides the most granular control and response capabilities specifically for malwareresiding on and spreading betweenhosts. RADIUS (Option B) and IPsec VPNs (Option D) focus on access control and encryption of data in transit, respectively, but do not provide the behavioral analysis needed to stop a running malware outbreak once the network has already been accessed.

A company published software that had a security vulnerability, and an attacker used the vulnerability to steal critical information from the environment. The issue was reported by the security team, and the administrator was instructed to run shift-left security tests before publishing the software. Which component of the software development pipeline must be recommended to run the tests?
正解：C
解説：
Shift-left security means running security tests earlier in the development lifecycle. By integrating tests in the source code management stage (e.g., Git repositories), vulnerabilities can be detected and fixed before software is built and deployed, reducing the risk of publishing insecure code.
