In IKEv1 policy configuration for Cisco ASA, two key commands are required to define the encryption and hashing algorithms:

A: encryption aes-256 defines the encryption method for the IKE SA.

E: hash sha-256 ensures SHA-256 is used as the integrity mechanism during IKE phase 1.

According to Cisco documentation and SCAZT (Section 1: Cloud Security Architecture, Pages 19–22), these two components are essential to negotiating a secure VPN tunnel. The provided config uses group 1 (modp768), which is weak by today’s standards and could also lead to negotiation failure. However, from the available options, encryption and hash are the two required for tunnel success.

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.

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.
