Checklist of ISO/IEC 27001-A.13.1.1 Network controls


Networks are crucial components of modern organizations, allowing them to connect with other entities and share data. 

As such, network security is a key aspect of information security, and it is essential to ensure that networks are protected against unauthorized access, interception, and misuse. 

This is where A.13.1.1 Network controls come in, which requires organizations to establish controls to secure their networks.

In this article, we will explore A.13.1.1 Network controls and provide a sample checklist that can help organizations assess their network security controls.

Sample Checklist:

  • Is there a policy covering both wired and wireless networks?
  • Are computer operations separate from network operations?
  • Are there adequate security protection mechanisms on the networks, such as firewalls, intrusion detection/prevention systems, and anti-virus/anti-malware software?
  • Is there appropriate logging and monitoring of the network and its devices to detect and respond to security incidents?
  • Are there ‘fail-proof’ authentication procedures for all access to the organization’s network?
  • How are network access points secured against unauthorized access?
  • How does the system limit access by authorized individuals to legitimate applications/services?
  • Are users authenticated appropriately at logon, including dial-in and remote/Web users?
  • How are network nodes authenticated?
  • Are distinct security domains established using firewalls, VLANs, VPNs, etc. to separate sensitive areas of the network?
  • Are privileged system management and remote support ports, such as secure modems and challenge-response systems, protected against unauthorized access?
  • Are key lock-out systems in place to prevent unauthorized access to network devices?
  • Is there a system in place to respond to network security incidents, including incident reporting, investigation, and resolution?

A.13.1.1 Network controls is an essential aspect of information security that requires organizations to establish controls to secure their networks. 

By following the sample checklist provided above, organizations can assess their network security controls and identify any areas that need improvement. 

With adequate network security controls in place, organizations can minimize the risk of network breaches, protect their sensitive data, and maintain the trust of their stakeholders.
