질문 # 42
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?
정답：C
설명：
Multi-Factor Authentication (MFA) strengthens user account security by requiring additional verification factors beyond passwords, such as tokens or biometrics. Even if credentials are stolen, MFA prevents unauthorized access, directly addressing the breach scenario.
질문 # 43
How is generative AI used in securing network?
정답：D
설명：
Generative AI enhances network security by identifying anomalies in traffic patterns. It learns normal network behavior and flags deviations that may indicate threats, such as intrusions or data exfiltration attempts.

How is generative AI used in securing networks?
정답：D
설명：
The integration ofArtificial Intelligence (AI)andGenerative AI (GenAI)into network security is a pivotal component of theCisco SDSI v1.0blueprint. While traditional security mechanisms rely on deterministic rules and static signatures, GenAI leverages large-scale telemetry data to understand the baseline behavior of a specific network environment. By processing vast amounts of flow logs, packet metadata, and user activity, AI models candetect unusual patterns-often referred to as anomalies-that signify sophisticated threats such as zero-day exploits, lateral movement, or slow-and-low data exfiltration.
In a modern security architecture, GenAI enhances the "Visibility and Monitoring" domain by identifying deviations that would be invisible to human analysts. For instance, if an application suddenly changes its communication frequency or connects to a previously unknown internal segment, the AI can flag this as a potential compromise. Unlike Option A or B, which focus on operational efficiency and performance, or Option C, which is a reporting and compliance function, the use of AI forbehavioral analyticsdirectly strengthens the threat detection lifecycle. Cisco products likeSecure Network Analytics(Stealthwatch) and Cognitive Intelligenceuse these AI capabilities to transition from reactive defense to a proactive posture, reducing the window of opportunity for attackers and aligning with the Cisco SAFE principle of continuous monitoring and pervasive visibility.

질문 # 45
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?
정답：D
설명：
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.

질문 # 46
A retail company is facing a series of cyberattacks targeting web servers, which results in disruptions to online services. Upon investigation, the security team identified that these attacks involved invalid HTTP request headers, which were used to exploit vulnerabilities in the web application. To safeguard the company websites against similar threats in the future, the security team must deploy a security solution specifically designed to detect and block such malicious web traffic. Which security product must be used to protect the websites from similar attacks?
정답：C
설명：
The cyberattacks described target theapplication layer (Layer 7), specifically exploiting vulnerabilities through malformed HTTP headers. AWeb Application Firewall (WAF)is the specialized security solution required to mitigate these threats. Unlike standard firewalls that inspect traffic at the network and transport layers (IPs and Ports), a WAF performs deep inspection of HTTP/HTTPS traffic.
A WAF-such as those integrated into theCisco Secure Firewallor cloud-native WAF services-understands the structure of web requests. It can identify and block sophisticated attacks like SQL injection, Cross-Site Scripting (XSS), and the specific "invalid HTTP request headers" mentioned in the scenario. By applying a set of rules (often based on the OWASP Top 10), the WAF filters out malicious requests before they reach the web server.Antivirus software(Option A) andHost-based firewalls(Option D) protect the server's operating system from malware and unauthorized connections but cannot inspect the logic of a web request. A Traditional Firewall(Option B) would simply see the traffic as "allowed" on Port 443 and pass it through.
Implementing a WAF is a critical architectural requirement in the Cisco SDSI "Applications" domain to protect customer-facing web services from exploitation.
