NEW QUESTION # 55
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 # 56
After deploying a new API, the security team must identify the components of the application that are exposed to the internet and whether there are application authentication risks. Which technology must be deployed to discover the applications services and monitor for authentication issues?
Answer: C
Explanation:
Securing APIs requires visibility into the "runtime" behavior of the application.API trace analysis(often part of anAPI Securitysolution like Cisco Panoptica) is the technology used to automatically discover API endpoints and analyze the traffic flowing through them. This process identifies "shadow APIs" (undocumented endpoints) that are exposed to the internet and inspects the headers and payloads for authentication risks, such as missing tokens or broken object-level authorization (BOLA).
By monitoring actual traffic traces, the security team can confirm if the API is following the intended security design or if it is leaking sensitive data due to poor authentication implementation.Cloud Security Posture Management (CSPM)(Option A) focuses on the configuration of the cloud infrastructure (like an open S3 bucket) rather than the internal logic of an API's authentication.Secret scanning(Option C) is a "shift-left" technique used to find hardcoded passwords in source code during the build phase, not for monitoring live traffic.Cloud Workload Protection (CWPP)(Option D) focuses on protecting the underlying host or container from malware and exploits. Only API trace analysis provides the specific visibility into service discovery and application-layer authentication health required in the Cisco SDSI v1.0 objectives for modern DevSecOps environments.
NEW QUESTION # 57
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 # 58
Which benefit does AI provide in network security?
Answer: B
Explanation:
AI in network security enhances threat detection and vulnerability identification by analyzing large volumes of traffic and encryption patterns. It can automatically detect risks such as weak TLS algorithm usage, which would otherwise be difficult to identify quickly with manual processes.
NEW QUESTION # 59
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: D
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.
