In Cisco ASA configurations using IKEv2, the integrity command defines the hash algorithm. To use SHA-
512, the correct syntax is:
integrity sha512
Without this, the IKEv2 proposal is considered incomplete or mismatched with the peer. The encryption command sets encryption (AES-256, etc.), not hashing. The correct structure is:
crypto ikev2 policy <#>
encryption aes-256
integrity sha512
group 2
prf sha512
lifetime 86400

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.

MITRE ATT&CK is a globally accessible knowledge base that catalogs adversarial tactics and techniques based on real-world observations. According to SCAZT Section 6: Threat Response (Page
113), this framework enables security professionals to map and anticipate adversarial behavior throughout the attack lifecycle. It supports threat modeling, detection engineering, and incident response.
