Why Cisco Today: Cisco's architecture directly mitigates today's most critical threats by providing deep operational technology (OT) visibility to prevent industrial sabotage, network-level enforcement and microsegmentation against critical RCE vulnerabilities in SAP and N-central, and correlated telemetry to stop state-sponsored malware targeting enterprise servers.

Sabotage Attack on Refrigeration Controllers (OT/ICS)

1. Threat — Sabotage Attack on Refrigeration Controllers by Iranian state actors (IRGC)
2. Cisco Product(s) — Cisco Cyber Vision, Cisco Secure Equipment Access
3. Configuration Guidance — In Cisco Cyber Vision, navigate to the asset inventory dashboard (verify in current console) to discover and profile all connected refrigeration controllers and industrial IoT devices. In Cisco Secure Equipment Access, navigate to Access Management -> Policies to enforce Zero Trust remote access, ensuring only authorized operators can reach these specific industrial assets.
4. Coverage Assessment — Strong

SAP NetWeaver and Web Dispatcher CVSS 10.0 RCE Flaws

1. Threat — SAP NetWeaver and Web Dispatcher unauthenticated RCE vulnerabilities (CVSS 10.0)
2. Cisco Product(s) — Cisco Secure Firewall, Cisco Secure Workload
3. Configuration Guidance — In the Secure Firewall Management Center (FMC), navigate to Policies -> Access Control -> Intrusion. Ensure the latest Talos rule updates are downloaded and set the policy to "Drop and Generate Events" for SAP-specific exploit signatures. In Cisco Secure Workload, navigate to Policies -> Workspaces (verify in current console) to enforce microsegmentation, isolating SAP servers from untrusted network segments.
4. Coverage Assessment — Strong

Able2Shell N-central Zero-Days

1. Threat — "Able2Shell" Zero-Days (33 vulnerabilities) affecting N-able N-central Hosted Environments and on-premises servers
2. Cisco Product(s) — Cisco Secure Firewall, Cisco Secure Network Analytics
3. Configuration Guidance — In the Secure Firewall Management Center (FMC), navigate to Policies -> Access Control and create a temporary rule blocking inbound internet connections to on-premises N-central servers until patches are applied. In Cisco Secure Network Analytics, monitor the Dashboard -> Top Alarms for anomalous lateral movement or command-and-control traffic originating from N-central server IP addresses.
4. Coverage Assessment — Strong

Turla "Cereal" Malware Targeting Microsoft Exchange

1. Threat — Russian Turla Hackers Use New "Cereal" Malware to Steal Emails from Microsoft Exchange
2. Cisco Product(s) — Cisco Secure Endpoint, Cisco XDR
3. Configuration Guidance — In the Cisco Secure Endpoint console, navigate to Management -> Policies and ensure "Exploit Prevention" and "Malicious Activity Protection" are enabled in blocking mode for your Exchange server host groups. In Cisco XDR, navigate to Integrations to ensure endpoint and email telemetry are actively correlating to detect Cereal malware indicators of compromise (IOCs).
4. Coverage Assessment — Integration-Dependent
5. Integration Note — Cisco XDR integrates with Microsoft Defender for Endpoint (for malware and lateral movement detection on Windows Servers) and Microsoft Defender for Office 365 (for email security and incident response) to provide comprehensive coverage against Exchange-targeted espionage.
