Network Security

Use security techniques and related management procedures (e.g., firewalls, security appliances, network segmentation, intrusion detection) to authorise access and control information flows from and to networks.

Value Drivers

  • Corporate security technology protected
  • Reliable information secured
  • Corporate assets protected
  • Network security managed in a consistent manner
  Risk Drivers
  • Failure of firewall rules to reflect the organisation’s security policy
  • Undetected unauthorised modifications to firewall rules
  • Compromised overall security architecture
  • Security breaches not detected in a timely manner

View Control Practices  help

Hide Control Practices  help

  1. Establish, maintain, communicate and enforce a network security policy (e.g., provided services, allowed traffic, types of connections permitted) that is reviewed and updated on a regular basis (at least annually).
  2. Establish and regularly update the standards and procedures for administering all networking components (e.g., core routers, DMZ, VPN switches, wireless).
  3. Properly secure network devices with special mechanisms and tools (e.g., authentication for device management, secure communications, strong authentication mechanisms). Implement active monitoring and pattern recognition to protect devices from attack.
  4. Configure operating systems with minimal features enabled (e.g., features that are necessary for functionality and are hardened for security applications). Remove all unnecessary services, functionalities and interfaces (e.g., graphical user interface [GUI]). Apply all relevant security patches and major updates to the system in a timely manner.
  5. Plan the network security architecture (e.g., DMZ architectures, internal and external network, IDS placement and wireless) to address processing and security requirements. Ensure that documentation contains information on how traffic is exchanged through systems and how the structure of the organisation’s internal network is hidden from the outside world.
  6. Subject devices to reviews by experts who are independent of the implementation or maintenance of the devices.
