The CVD Policy Framework
NIS2 requires essential entities to establish procedures for vulnerability handling and disclosure. For telecom, this extends beyond internal software to the entire vendor supply chain.
Intake & Reception
Establish secure channels for researchers and customers to report vulnerabilities (e.g., bug-bounty@company.com).
Verification & Triage
Internal security teams validate the vulnerability and determine its CVSS score/impact on telecom operations.
Remediation & Patching
Coordinate with vendor partners to develop and test patches for core equipment or software.
Public Disclosure
Once a fix is available, release a security advisory ensuring users can update their systems.
Coordinated Handling for RAN/Core
Vulnerability management in network elements (5G Core, RAN) requires coordination with equipment vendors (OEMs).
- Security.txt: Deploy a
well-known/security.txton all public gateways. - PGP Encryption: Provide a public PGP key for secure vulnerability submission.
- Safe Harbor: Clearly state that researchers acting in good faith will not face legal action.
- VNDB Integration: Map internal vulnerabilities to the ENISA European Vulnerability Database.
