Cisco Talos is Cisco’s threat intelligence organization, delivering real-time threat intelligence and malware analytics to help organizations detect and prevent threats before they impact the network. According to the SCAZT guide, Talos provides comprehensive coverage of threat data including signatures, indicators of compromise, and context-driven analytics. This intelligence feeds into Cisco security platforms such as Cisco SecureX and Cisco Secure Endpoint to enhance detection, investigation, and response capabilities. Talos is explicitly referenced in the Threat Response section as the primary source of threat intelligence and malware analytics that supports cloud and endpoint security frameworks.

Cisco Identity Services Engine (ISE) is the central policy engine for posture assessments. As outlined in the SCAZT guide (Section 2: User and Device Security, Pages 39–44), to implement posture assessment and client provisioning correctly, an administrator must create posture policies within Cisco ISE and configure the Network Access Device (NAD)—such as a switch, WLC, or firewall—for redirection. This redirection sends the user to the posture portal, where ISE verifies the Secure Client modules (such as AnyConnect) and enforces compliance with antivirus signatures and OS updates.

ISE evaluates endpoint health based on pre-defined compliance rules and supports automatic remediation via the client provisioning portal. This ensures consistency and policy enforcement across distributed environments.

To preserve the user for investigation while immediately revoking access, the correct approach is to disable the user in the Duo Admin Panel. This action blocks authentication without deleting logs or user data. Simultaneously, resetting the password from Active Directory ensures any potentially compromised credentials are revoked.

According to SCAZT (Section 2: User and Device Security, Pages 40–44), disabling user accounts in Duo offers secure containment during security incidents while maintaining data for forensic review.

Cisco Secure Endpoint (formerly AMP for Endpoints) includes an “Inbox” tab where detected threats and flagged endpoints are listed. When Duo Trusted Endpoints integration is in place, an endpoint may be denied access if it fails posture checks. The correct workflow includes reviewing the machine’s status in Cisco Secure Endpoint and marking the incident as “Resolved” in the Inbox tab to restore authentication.

This process is described in SCAZT Section 2 (User and Device Security, Pages 44–46) for enforcing endpoint trust with Secure Endpoint and Duo Trusted Endpoints integration.

The provided JSON-like policy structure shows a segmentation rule with action " BLOCK " and filters referencing the HTTPS Consumer and HTTPS Provider. However, to block HTTP, you must define the protocol explicitly in the parameters. The attribute “l4_params” is currently empty. According to Cisco Secure Workload best practices (SCAZT Section 4: Application and Data Security, Pages 88–91), Layer 4 parameters (l4_params) must be used to specify protocols such as HTTP or port 80. Without defining HTTP here, the policy does not apply to HTTP traffic.

Cisco Extended Detection and Response (XDR) leverages telemetry from Cisco Secure Endpoint, Secure Email, Secure Network Analytics, and other sources to correlate threat detections with contextual data, such as asset value and business impact. This allows Cisco XDR to prioritize threats not only by the risk of the detection but also by the importance of the affected asset—essentially assessing the risk to business. This dynamic and context-aware prioritization method enables security teams to address the most impactful threats first.

The exhibit shows DNS Block as the reason and lists 10.1.108.100 as the Responder IP, with the Initiator being 10.1.113.7. In Cisco Secure Firewall Management Center reports, the “Initiator IP” is the source of the request and the “Responder IP” is the source of the response. Since the DNS security intelligence engine flagged the traffic, and 10.1.108.100 was the responder, the blocked traffic corresponds to a DNS response from that IP.

The screenshot from Cisco Secure Cloud Analytics shows a Role Violation alert. According to the “Supporting Observations” pane, the device with IP 10.201.0.15 is assigned the role of Domain Controller but has demonstrated traffic behavior matching an FTP client, connecting to ports 20, 21, 115, 152, 989, and 990. This discrepancy triggered the alert.

Cisco SCAZT documentation emphasizes that devices acting outside their expected network roles (e.g., a domain controller acting as an FTP client) indicate potential compromise or misuse. Role-based anomaly detection is part of Visibility and Assurance mechanisms where baseline behaviors are continuously monitored and flagged when changes occur outside expected policy or operational norms.
