Telecom networks are a high-value target. Attackers exploit everything from outdated SS7 signaling to exposed APIs in 5G service-based architectures. Regulation has caught up, but compliance alone won’t protect operators. That’s why security policies are more than paperwork—they’re the backbone of telecom defense.

Below we’ll break down practical telecom security policy examples that operators can implement, adapt, or benchmark against. Think of these as a blueprint for closing doors before attackers even start rattling the handle.

1. Access Control and Authentication Policy

Objective: Limit access to network infrastructure and prevent unauthorized use of signaling systems.

• Multi-factor authentication for employees, contractors, and third-party vendors.
• Role-based access control for network elements (HSS, IMS, EPC, 5G Core).
• Automated log correlation to detect abnormal login attempts.
• Revocation procedures for compromised credentials.

Why it matters: Stolen operator credentials are a common attack vector. Without strong access control, you’re inviting attackers to walk in through the front door.

2. Incident Response and Breach Notification Policy

Objective: Define how to react when—not if—a breach occurs.

• Establish a 24/7 incident response team with clear escalation levels.
• Maintain pre-approved playbooks for telecom-specific attacks (e.g., rogue roaming, SS7 injection, signaling storms).
• Notify regulators and affected customers within mandated timeframes (NIS2, EECC).
• Run quarterly tabletop exercises simulating telecom-specific incidents.

Why it matters: Operators often delay responses because they’re stuck deciding who should act. A well-defined policy removes hesitation.

3. Lawful Interception and Data Privacy Policy

Objective: Balance compliance with privacy protection.

• Define clear processes for handling government interception requests.
• Enforce strict separation between LI functions and operational network management.
• Monitor access to LI systems with immutable audit logs.
• Apply encryption to customer data at rest and in transit (yes, including signaling payloads).

Why it matters: Lawful interception backdoors are prime targets for attackers. If you don’t police them, someone else will exploit them.

4. Patch Management and Vulnerability Handling Policy

Objective: Keep telecom infrastructure aligned with the patch cycle.

• Maintain a vulnerability disclosure program and align with GSMA FS.11 standards.
• Prioritize CVEs affecting telecom protocols (SS7, Diameter, GTP, SIP).
• Apply emergency patches within 72 hours of release.
• Track deviations and report them at the CISO level.

Why it matters: Operators often run critical equipment on unpatched firmware for years. A documented policy forces accountability.

5. Supply Chain and Vendor Security Policy

Objective: Control risks introduced by third-party vendors and equipment providers.

• Require vendors to follow NIS2 and CRA-aligned security standards.
• Perform security audits on equipment (core, RAN, O-RAN components).
• Demand SBOMs (Software Bill of Materials) for all vendor software.
• Define procedures for replacing compromised or non-compliant equipment.

Why it matters: Nation-state threats often target vendors first. If your supply chain is weak, your network is weak.

6. Network Monitoring and Logging Policy

Objective: Ensure continuous visibility into signaling, traffic, and anomalies.

• Define mandatory logging for all critical network functions.
• Deploy intrusion detection systems specifically built for telecom (signaling-aware IDS).
• Store logs securely for at least 12 months for compliance and forensic analysis.
• Automate correlation between roaming activity, signaling patterns, and fraud detection.

Why it matters: You can’t defend what you don’t see. Logs are the black box flight recorder of your network.

7. Compliance and Audit Policy

Objective: Align with telecom regulations while ensuring internal accountability.

• Map policies to NIS2, EECC, CRA, and local regulator requirements.
• Conduct annual external audits of network security.
• Benchmark against GSMA security guidelines (FS.11, FS.19).
• Maintain board-level reporting for compliance metrics.

Why it matters: Regulators don’t care about excuses. A compliance policy keeps you ready when the audit team shows up.

Final Thoughts

Security policies are often treated as checklists for auditors. In reality, they should be living documents—adapted to evolving telecom threats, updated with every new CVE, and enforced across every business unit.

Operators who treat policy as strategy, not paperwork, stand a much better chance of defending their networks against both cybercriminals and nation-state adversaries.
