A network security policy delineates guidelines for computer network access, determines policy enforcement, and lays out the architecture of the organization’s network security environment and defines how the security policies are implemented throughout the network architecture.
Network security policies describes an organization’s security controls. It aims to keep malicious users out while also mitigating risky users within your organization. The initial stage to generate a policy is to understand what information and services are available, and to whom, what the potential is for damage, and what protections are already in place.
The security policy should define the policies that will be enforced – this is done by dictating a hierarchy of access permissions – granting users access to only what they need to do their work.
These policies need to be implemented in your organization written security policies and also in your IT infrastructure – your firewall and network controls’ security policies.
What is network security policy management?
Network security policy management refers to how your security policy is designed and enforced. It refers to how firewalls and other devices are managed.
Cyber Security Policies as Part of IT Security Policy
A good IT security policy contains the following essentials:
- Purpose
- Audience
- Information security objective
- Authority and access control policy – This includes your physical security policy
- Data classification
- Data support and operations
- Security awareness and behavior
- Responsibility, rights, and duties
A cyber security policy is part of your overall IT security. A cybersecurity policy defines acceptable cybersecurity procedures. Cybersecurity procedures explain the rules for how anyone with potential network access can access your corporate resources, whether they are in your physical offices, work remotely, or work in another company’s offices (for example, customers and suppliers), send data over networks. They also determine how organization’s manage security patches as part of their patch management policy.
A good cybersecurity policy includes the systems that your business is using to protect your critical information and are already in place, including firewalls. It should align with your network segmentation and micro-segmentation initiatives.

Examining the Security Policy Management Maturity Model
Does the following scenario sound familiar? Your network complexity is getting out of hand with too many firewalls, routers, switches, secure web gateways and more, as well as the related security policies. New network security devices with more granular and different types of controls have recently been or are being deployed in the network. At the same time the business is putting more demands on you to manage "ASAP" with requirements changing regularly. You don't have proper visibility of the security policies, compliance audits are a major burden, you can't keep up with all of the changes and you can't possibly know the impact of a security change or risk to a application that is critical to the business.If any or all of the above sounds familiar, you're not alone.Many enterprise networks are too complex, with numerous security devices and thousands of policies that must be managed across multiple vendors, different stakeholders and geographical locations. As new security technologies from different vendors are introduced into production environments, organizations not only have a maturity level in terms of what devices and capabilities are deployed, but also with regards to how the security policy is managed. From our work with more than 1000 enterprises from around the globe, we have been able to gain valuable insights used to craft the security policy management maturity model. This maturity model can help organizations recognize their current environment and to provide a roadmap for simplifying security policy management and gaining the crucial business perspective that is often lacking.I'm pleased to be joined on a webcast tomorrow with Eric Ogren of The Ogren Group, where we'll examine the security policy management maturity model and:Explore the challenges involved with managing the security policy such as understanding network topology and traffic flows, application connectivity requirements, risks in the policy, the purpose of each rule in the estate, and much more;Drill down into the benefits that can be achieved at each level;Offer recommendations for moving to a more automated and application-centric approach that involves security administrators, network operations, compliance officers, application owners and senior management.I hope to see you on thewebcast tomorrow and get your feedback on the maturity model.
