New Guidance for SIEM and SOAR Implementation
May 27, 2025
Today, CISA, in collaboration with the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC) and other international and U.S. partners, released new guidance for organizations seeking to procure Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platforms. This guidance includes the following three resources: Implementing SIEM and SOAR Platforms – Executive Guidance outlines how executives can enhance their organization’s cybersecurity framework by implementing these technologies to improve visibility into network activities, enabling swift detection and response to cyber threats. Implementing SIEM and SOAR Platforms – Practitioner Guidance focuses on how practitioners can quickly identify and respond to potential cybersecurity threats and leverage these technologies to streamline incident response processes by automating predefined actions based on detected anomalies. Priority Logs for SIEM Ingestion – Practitioner Guidance offers insights for prioritizing log ingestion into a SIEM, ensuring that critical data sources are effectively collected and analyzed to enhance threat detection and incident response capabilities tailored for organizations. CISA encourages organizations to review this guidance and implement the recommended best practices to strengthen their cybersecurity.

Advisory Update on Cyber Threat Activity Targeting Commvault’s SaaS Cloud Application (Metallic)
May 22, 2025
Commvault is monitoring cyber threat activity targeting their applications hosted in their Microsoft Azure cloud environment. Threat actors may have accessed client secrets for Commvault’s (Metallic) Microsoft 365 (M365) backup software-as-a-service (SaaS) solution, hosted in Azure. This provided the threat actors with unauthorized access to Commvault’s customers’ M365 environments that have application secrets stored by Commvault. See the following resource for more information: Notice: Security Advisory (Update). CISA believes the threat activity may be part of a larger campaign targeting various SaaS companies’ cloud applications with default configurations and elevated permissions. CISA urges users and administrators to review the following mitigations and apply necessary patches and updates for all systems: Monitor Entra audit logs for unauthorized modifications or additions of credentials to service principals initiated by Commvault applications/service principals. Handle deviations from regular login schedules as suspicious. For more information, see NSA and CISA’s Identity Management guidance, as well as CISA’s guidance on Identity, Credential, and Access Management (ICAM) Reference Architecture. Review Microsoft logs (Entra audit, Entra sign-in, unified audit logs) and conduct internal threat hunting in alignment with documented organizational incident response polices. (Applies to single tenant apps only) Implement a conditional access policy that limits authentication of an application service principal to an approved IP address that is listed within Commvault’s allowlisted range of IP addresses. Note: A Microsoft Entra Workload ID Premium License is required to apply conditional access policies to an application service principal and is available to customers at an additional cost.[1] For certain Commvault customers, rotate their application secrets, rotate those credentials on Commvault Metallic applications and service principles available between February and May 2025.[2] Note: This mitigation only applies to a limited number of customers who themselves have control over Commvault’s application secrets. Customers who have the ability to, if applicable, should establish a policy to regularly rotate credentials at least every 30 days. Review the list of Application Registrations and Service Principals in Entra with administrative consent for higher privileges than the business need. Implement general M365 security recommendations outlined in CISA’s Secure Cloud Business Applications (SCuBA) Project. Precautionary Recommendations for On-premises Software Versions Where technically feasible, restrict access to Commvault management interfaces to trusted networks and administrative systems. Detect and block path-traversal attempts and suspicious file uploads by deploying a Web Application Firewall and removing external access to Commvault applications [CSA-250502]. Apply the patches provided [3] and follow these best practices [4]. Especially monitor activity from unexpected directories, particularly web-accessible paths. CISA added CVE-2025-3928 to the Known Exploited Vulnerabilities Catalog and is continuing to investigate the malicious activity in collaboration with partner organizations.
