SECURITY MEASURES
1. Security Policy: Develop a security policy. This will limit liability exposure and is the basis for applying appropriate security to the enterprise telecommunications infrastructure.
2. Security Awareness: Implement a strong security awareness, training and education program.
3. Monitor Access: Know who, when, why and how users are accessing your systems.
4. Routine Backups: Routinely back up all systems, store backups off-site and test the backups.
5. Integrity Checks: Run system integrity checks and compare using off-line encrypted checksums.
