Pass the Cisco CCNP Security 300-740 Questions and answers with ValidTests

The MITRE ATT&CK framework is a globally recognized knowledge base that catalogs adversary behavior. One of its most crucial components is its matrix of Tactics and Techniques.

“Techniques for accessing credentials” is a key example of the Techniques layer within the MITRE ATT&CK matrix.

These techniques describe how adversaries achieve tactical objectives—such as gaining access to credentials for lateral movement or privilege escalation.

In the SCAZT guide under Threat Response, organizations are advised to map telemetry and detection tools (like Cisco Secure Analytics, SecureX, and Secure Endpoint) to the MITRE ATT&CK framework to enhance visibility and accelerate threat response.

The JSON configuration shown is missing a specific Layer 4 parameter definition for port 25 (SMTP). Although the protocol (proto: 6, which is TCP) is defined, without specifying the actual port in the l4_params array, traffic filtering will not trigger on SMTP. Therefore, the engineer must add "port": [25, 25] to the l4_params section to ensure traffic on port 25 is blocked.

The screenshot from Cisco ISE shows a configuration of a “File Condition” posture check that verifies the existence and version of the “Srv.sys” file in the System32 directory. This is a known method to validate if a Windows device has received a critical security patch (in this case, one related to protection against the WannaCry vulnerability, MS17-010). Cisco ISE does not rely solely on a patch management system for this type of validation but can use specific file version and path checks. Therefore, the correct posture condition is File Condition.

According to the SCAZT documentation, web application firewalls (WAFs) designed to protect against zero-day Distributed Denial of Service (DDoS) attacks leverage adaptive and behavioral-based algorithms. These algorithms dynamically analyze traffic patterns, baseline normal behavior, and detect anomalies that could indicate novel or zero-day attacks. Unlike signature-based detection, adaptive and behavioral methods adjust in real-time to emerging threats, learning from ongoing traffic without relying on pre-defined rules. This proactive approach enables rapid detection and mitigation of unknown DDoS vectors, critical for cloud and network security where threats evolve constantly.

Based on the Cisco Tetration segmentation policy and the requirement to allow only web server communication (HTTP/HTTPS):

Rule 1 allows HTTP (port 80) — required

Rule 2 allows HTTPS (port 443) — required

Rule 3 allows SSH — not needed for web communication

Rule 4 allows UDP port 68 (DHCP) — not relevant to application-layer web server traffic

Therefore, Rules 3 and 4 are unnecessary and should be deleted for policy optimization, which aligns with zero-trust and least-privilege access design as outlined in SCAZT Section 4 (Application and Data Security, Pages 86–90).

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.

Cisco XDR (Extended Detection and Response) leverages artificial intelligence (AI) and machine learning (ML) to prioritize actions based on the severity, context, and impact of detected threats. According to the Designing and Implementing Secure Cloud Access for Users and Endpoints (SCAZT) documentation, Cisco XDR consolidates telemetry from endpoints, networks, cloud, email, and identity sources and applies AI/ML models to reduce alert fatigue, correlate signals, and surface only the highest-risk threats for response.

This intelligent correlation and prioritization mechanism enables security analysts to focus on critical incidents first, dramatically reducing mean time to detect (MTTD) and mean time to respond (MTTR). Unlike static mechanisms such as antivirus updates or passive traffic inspection, AI-driven analytics enable Cisco XDR to make data-informed decisions across the entire attack surface.

In Cisco Secure Endpoint (formerly AMP for Endpoints), isolating an infected machine is the most immediate action to contain the threat. Isolation cuts the endpoint off from all network communication except to the management console, allowing the analyst to investigate further while preventing lateral movement or data exfiltration.

According to SCAZT Section 6: Threat Response (Pages 114–117), isolation is a recommended first response in the event of malware detection.
