Cisco SecureX integrates multiple security tools with SIEM and SOAR platforms and provides automated incident response workflows to speed up detection, investigation, and remediation.
質問 # 19
A restaurant distribution center recently suffered a password spray attack targeting the Cisco Secure Firepower Threat Defense VPN headend. The attack attempts to gain unauthorized access by trying common passwords across many accounts. The attack poses a significant security threat to the organization's remote access infrastructure. To enhance the security of VPN setup and minimize the risk of similar attacks in the future, the IT security team must implement effective mitigation measures. Which technique effectively reduces the risk of this type of attack?
正解：A
解説：
Enabling AAA authentication on the default connection profiles ensures that all VPN access attempts must go through strong authentication. This directly mitigates password spray attacks by enforcing centralized authentication controls, enabling account lockout, and supporting additional protections such as multifactor authentication.
質問 # 20
An employee of a pharmaceutical company accidentally checked in code that contains AWS secret keys to a public GitHub repository, which exposes production resources to attackers. Which mitigation strategy must a security engineer recommend to prevent future reoccurrence?
正解：A
解説：
Accidental exposure of sensitive credentials, such as API keys or AWS secrets, is a major risk in modern DevOps environments. To prevent such incidents from occurring, the most effective technical control is the implementation of aSource Code Management (SCM) precommit hook. A precommit hook is a script that runs locally on a developer's machine before a commit is finalized and pushed to a remote repository.
According to Cisco's DevSecOps design principles, precommit hooks can be configured to scan the code for specific patterns that resemble secrets (e.g., regex for AWS Access Key IDs). If the scanner detects a secret, it automatically aborts the commit, forcing the developer to remove or properly encrypt the sensitive data before the code can leave their local machine. This provides an immediate "shift-left" safety net that stops the leak at the source.
While aWeb Application Firewall (WAF)(Option A) protects against external attacks andPort Security (Option B) manages Layer 2 access, neither can prevent a developer from pushing code to GitHub. Aphishing education campaign(Option C) is beneficial for general security awareness but does not provide the automated, technical enforcement required to block credential leakage. By configuring precommit hooks, the pharmaceutical company establishes a proactive defense mechanism that significantly reduces the risk of credential exposure and aligns with the automation objectives of the Cisco SDSI curriculum.
質問 # 21
An oil and gas company recently faced a security breach when an employee's notepad, which contained critical login credentials, was stolen. The incident led to unauthorized access to a user account, which posed a significant risk to sensitive company data and operations. The company wants to adopt a security measure that enhances user account protection. Which action must be taken to prevent breaches like this from happening in the future?
正解：C
解説：
The scenario described-where physical theft of written credentials led to a breach-is a classic failure of single-factor authentication. To mitigate this risk, the company must implementMulti-Factor Authentication (MFA). MFA requires users to provide two or more verification factors to gain access to a resource, typically categorized as something you know (password), something you have (a smartphone or hardware token), or something you are (biometrics).
According to Cisco Security Infrastructure design best practices, MFA (such asCisco Duo) ensures that even if an attacker possesses valid credentials (the "something you know" from the stolen notepad), they cannot gain access without the second factor (the "something you have"). This effectively neutralizes the threat of stolen passwords.Single Sign-On (SSO)(Option B) improves user experience and centralizes management but does not, by itself, stop an attacker who has the master password.Updating the RADIUS server(Option C) is a maintenance task that doesn't change the authentication logic, and apassword expiration policy(Option D) would only limit the "shelf life" of the stolen credentials rather than preventing their initial use. MFA is the most robust architectural control for enhancing identity security and is a core pillar of a Zero Trust framework.

質問 # 22
A global energy company moved a monolithic application from the data center to public cloud.
Over time, the company added many capabilities to the application, and it is now difficult for the application team to scale it. The application owner decided to modernize the application by moving to a Kubernetes cluster. However, he wants to ensure that the new application architecture provides a container network interface that is scalable, offers options for cloud-native security, and helps with visibility and observability. Which solution must be used to accomplish the task?
正解：B
解説：
Cilium is a Kubernetes Container Network Interface (CNI) that provides scalability, cloud-native security with eBPF-based enforcement, and strong visibility/observability into network traffic between microservices. It is purpose-built to modernize applications running in Kubernetes clusters.
