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.

The policy includes three rules under the Apps scope. Rule #1 allows HR to communicate with IT on TCP port 23 (Telnet), but it is marked as “Default.” Rule #2 denies the same HR-to-IT Telnet traffic and is marked as “Absolute,” which takes precedence over any default rule. In Cisco Secure Workload (Tetration), an “Absolute” rule will override both “Default” and inherited rules. Therefore, even though there’s an allow in Rule #1, the deny in Rule #2 prevents HR from using Telnet to connect to IT.

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.
