CERT Operations Workbench

Overview#

A national CERT analyst arrives at their shift to find overnight advisories from three EU partner authorities, two new Sigma rules published by the community, an unanalyzed malware sample in the MWDB queue, and a MISP event from a sector ISAC flagging a new phishing kit. Without a consolidated workspace, that morning's triage requires switching between five separate interfaces, each with its own context and workflow. The CERT Operations Workbench brings all of these surfaces together into a single operational preset so the analyst can move from advisory review to malware triage to detection rule deployment without losing context or rebuilding their workspace from scratch.

The CERT Operations Workbench is a cyber-response workspace for national CSIRTs, sectoral CERT teams, and incident response organisations that need a consolidated view of threat detection, intelligence exchange, malware triage, automation, and advisory workflows. It is especially valuable for organisations operating within European or multi-national CERT networks where advisory intake, detection engineering, malware analysis, and controlled intelligence sharing must happen inside one coordinated operational surface.

Open Standards#

STIX 2.1 / TAXII 2.1 (OASIS): Threat intelligence objects are ingested, stored, and disseminated as STIX 2.1 bundles and indicators, with TAXII 2.1 feed configurations used for automated polling from partner CERT and ISAC sources.
MITRE ATT&CK: Threat actor attribution and detection engineering workflows are mapped to ATT&CK technique and tactic identifiers, enabling analysts to link malware behaviour and indicators to the framework's TTP taxonomy.
CACAO Security Playbooks v2.0 (OASIS): Response playbooks are imported, validated, and exported as CACAO v2.0 JSON documents, providing a standard interchange format for coordinating incident-handling procedures across CERT networks.
OpenC2 v1.1 (OASIS): Automated response actions defined within CACAO playbooks are executed via an OpenC2 v1.1 command producer/consumer, dispatching actions such as deny and contain to remote actuator endpoints.
Traffic Light Protocol (TLP): Intelligence objects ingested via STIX bundles carry TLP marking definitions (TLP:CLEAR through TLP:AMBER+STRICT) that are resolved and propagated to enforce access controls during cross-border sharing.
YARA: Malware triage and file analysis workflows consume and manage YARA rules for pattern-based artefact matching, with rules persisted and synchronised alongside sample queues.
Sigma: Detection engineering surfaces import, validate, and translate Sigma rules to SIEM back-end query languages, allowing analysts to review and deploy community-published rules against the constituency detection posture.
CVE / CVSS: Vulnerability enrichment within threat intelligence records uses CVE identifiers and CVSS score/vector fields, enabling analysts to correlate indicators against known vulnerabilities during triage.

Key Features#

Threat Detection Posture: Combines Suricata, Sigma rules, SIEM, and related detection surfaces into a single review space for ongoing monitoring across the national or sectoral constituency.
Threat Intelligence Exchange: Brings STIX/TAXII, MISP and MISP Modules, indicators, and intelligence report surfaces together for feed review and dissemination to constituency organisations.
Malware and Sandbox Analysis: Provides quick access to MWDB malware repositories and CAPE Sandbox-backed triage workflows for newly received samples, accelerating the path from unknown file to actionable indicators.
Playbook and Automation Support: Supports CACAO-style response automation and guided incident-handling pivots for repeatable CERT actions, reducing response time for known incident patterns.
CERT-Focused Presets: Narrows the broader cyber and DFIR workspace into a CERT-relevant operational view rather than requiring teams to assemble their own surface composition every session.

Use Cases#

National Advisory Monitoring: CERT operators review incoming advisories, indicators, and malicious artefacts from national and partner sources in one operational view, with enrichment from MISP and YARA available immediately.
Coordinated Incident Response: Teams move from new detections into playbook-driven response, malware review, and controlled intelligence distribution without leaving the workbench.
Detection Engineering Support: Analysts review new Sigma rules, Suricata signatures, and YARA patterns alongside feed content to update local detection posture against current threats.
Cross-Border CERT Collaboration: Multi-national response teams maintain a shared view of threat posture and response inputs during coordinated incidents, with TLP-appropriate access controls applied throughout.

Integration#

EU CERT and CSIRT network feeds from twelve national authorities.
STIX/TAXII, MISP and MISP Modules, Sigma rules, Suricata IDS, SIEM, YARA Engine, and related cyber integrations.
Malware analysis and DFIR surfaces including MWDB, CAPE Sandbox, and GRR Rapid Response.
Automation and response-playbook systems including CACAO and SOARCA.
