NEW QUESTION # 12
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?
Answer: B
Explanation:
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.
NEW QUESTION # 13
A developer is building new API functions for a cloud-based application. Before writing the code, the developer wants to ensure that destructive actions, including deleting and updating data, are properly protected by access control identifying sensitive fields such as those that contain passwords or personally identifiable information. Which approach must be used to score the risks proactively?
Answer: D
Explanation:
Open API Specification Analysis evaluates API definitions before code is written, identifying risky endpoints (such as delete or update functions) and sensitive fields (like PII or passwords). This allows developers to proactively score risks and apply proper access controls early in the design phase.
NEW QUESTION # 14
A company recently discovered that a former employee, who left to join a competitor, continued to access and exfiltrate sensitive data over several weeks after leaving. The breach highlighted vulnerabilities in the organization's data security and access management practices. To prevent such incidents in the future, the organization must adopt measures that detect and restrict unauthorized data access and transfer. Which mitigation strategy must be implemented to address the issue?
Answer: D
Explanation:
The scenario describes a typical "insider threat" involvingdata exfiltration. While the initial failure was likely in the off-boarding process (Identity Management), the technical control required to specifically "detect and restrict unauthorized data access and transfer" is aData Loss Prevention (DLP) strategy. DLP solutions are designed to monitor, detect, and block sensitive data from leaving the organization's control.
A robust DLP strategy-integrated across Cisco platforms likeEmail Security (ESA),Web Security (WSA), andCisco Umbrella-works by identifying sensitive content (such as customer lists, proprietary code, or financial data) using techniques like fingerprinting or keyword matching. If an unauthorized attempt is made to upload this data to a personal cloud drive or send it via email, the DLP engine intercepts and blocks the transfer. WhileAudit Logging(Option D) is essential for forensic investigationafterthe fact, it does not
"restrict" the transfer in real-time.WAFs(Option A) protect against external attacks on web servers, and Network Policies(Option B) control traffic flow but generally lack the content-awareness required to identify sensitive business data. Implementing DLP ensures that the organization's intellectual property remains protected even if an account remains active or a user has legitimate network access.
NEW QUESTION # 15
A pharmaceutical company needs a hub-and-spoke VPN topology. The design must be capable of building either partial or full mesh overlay networks. Which VPN solution must be implemented in the environment?
Answer: C
Explanation:
In the context of theDesigning Cisco Security Infrastructure (300-745 SDSI)blueprint,Dynamic Multipoint VPN (DMVPN)is the specialized architectural solution designed for scalable hub-and-spoke topologies that require the flexibility to evolve into partial or full mesh overlays. DMVPN leverages a combination of Multipoint GRE (mGRE) tunnels, Next Hop Resolution Protocol (NHRP), and IPsec encryption to create a dynamic environment.
The primary advantage of DMVPN is its ability to establish "on-demand" tunnels between spoke sites. In a traditional hub-and-spoke model, traffic between two spokes must transit the hub, which introduces latency and increases hub resource consumption. With DMVPN, spokes can use NHRP to discover the public IP addresses of other spokes and build direct tunnels between them automatically. This allows the pharmaceutical company to maintain a simple hub-and-spoke management model while benefiting from the performance of afull meshwhen traffic patterns demand it.
WhileSSL VPNs(Option D) andL2TP(Option B) are excellent for individual remote access, they are not designed for site-to-site mesh scalability.Crypto maps(Option C) represent the legacy method of building IPsec tunnels, which requires static, manual configuration of every peer relationship-making a full mesh practically impossible to manage at scale. DMVPN fulfills the Cisco SDSI objective of designing highly available and flexible secure infrastructure by automating the complexity of large-scale tunnel management.
NEW QUESTION # 16
An engineering company's Chief Financial Officer recently fall victim to a phishing scam by responding to an urgent email. The mail appeared to be from a trusted business partner, and it requested sensitive tax information. The incident led to significant financial and reputational damage. To prevent similar occurrences in the future, the security team must implement an effective mitigation strategy. Which mitigation strategy must the security team implement to prevent similar occurrences in the future?
Answer: D
Explanation:
A targeted education campaign directly addresses phishing by training employees, especially high-value targets like executives, to recognize social engineering attempts. While technical controls help, phishing primarily exploits human behavior, so awareness and training are the most effective preventive measures.
