The Secure Cloud Analytics alert indicates suspicious heartbeat-based connections from an internal server (ip-10-201-0-16) to multiple suspicious IPs over UDP/port 53 (DNS). This behavior suggests command-and-control (C2) activity or botnet communications.

B: Alerting the incident response (IR) team is a critical next step in escalating a verified threat as per SCAZT Section 6 (Threat Response, Pages 114–117).

D: Blocking the identified malicious IPs on perimeter firewalls or network access control devices is an appropriate containment step to disrupt communication.

Reinstallation (A/E) is premature without a full forensic investigation. Validating IDS logs (C) is useful but not immediate response-focused compared to actions B and D.

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.

From the firewall access rules provided, Rule 1 allows traffic from 20.1.1.10 (GCP VM) to 20.1.1.1 using HTTPS. However, this destination is not the actual mail server—the mail server resides at 192.168.200.10 (inside network). Therefore:

A: Rule 1 must be updated to reflect the correct destination: 192.168.200.10. Without this change, traffic is not permitted to the mail server.

D: NAT (Network Address Translation) is needed to translate the external address (e.g., 20.1.1.10) to access internal addresses (like 192.168.200.10). As per SCAZT and Cisco firewall policies, NAT enables proper packet delivery from public to private zones.

Rule 2, which denies all other traffic, is correctly placed after the specific allow rule. Therefore, moving it (Option B) would not help, and Options C and E are unrelated to resolving the immediate firewall access and routing issue.

After Cloudlock is integrated with Salesforce, full visibility into objects and data requires that Cloudlock has the “View All Data” permission enabled on the connected Salesforce account. This permission allows the Cloudlock API connection to access all user data, regardless of individual field-level or sharing rules. Without it, Cloudlock will be limited in its visibility scope.

As per SCAZT (Section 4: Application and Data Security, Pages 86–89), integration with SaaS platforms like Salesforce must include enabling comprehensive data visibility to perform effective risk analysis and policy enforcement.
