Cisco 300-740 Exam With Confidence Using Practice Dumps

The SCAZT documentation emphasizes that when Cisco Secure XDR identifies a high-risk threat (e.g., risk score 8 out of 10 for malware distribution, as shown in the exhibit), the first priority is to prevent lateral movement and data exfiltration. The recommended first response action is to isolate the affected endpoint from the network.

Cisco Secure Endpoint and XDR allow you to trigger an "isolate" response directly from the dashboard, cutting off all non-management communication from the compromised device. This preserves the environment and enables forensic analysis before removing malware or taking destructive actions like rebuilding the system.

According to the SCAZT guide, the “Always-on” deployment mode for Cisco Secure DDoS (including integration with Secure Web Application Firewall solutions) provides continuous protection for both volumetric and application-layer attacks. This deployment model ensures that all traffic flows through the scrubbing and WAF infrastructure without requiring traffic redirection only during attack events. It provides real-time mitigation and immediate detection, which is essential to address both volumetric attacks (e.g., SYN floods) and Layer 7 (application-layer) attacks such as HTTP floods and injection-based threats.

While “Hybrid” and “On-demand” modes are useful for specific use cases, only “Always-on” offers continuous and comprehensive protection required for environments that demand consistent uptime and threat prevention.

Web Application Firewalls (WAFs) use rate-based rules as one of the primary mechanisms to detect and mitigate Distributed Denial of Service (DDoS) attacks. According to the SCAZT Study Guide, Section 3 (Network and Cloud Security, Pages 74–77), rate-based rules dynamically detect unusual spikes in traffic and can throttle or block connections exceeding predefined thresholds. This form of protection is more adaptive and intelligent than standard ACLs or static filtering, enabling protection against zero-day and volumetric attacks that may not follow known patterns.
