A network security plan outlines network access rules, outlines the network security environment, and explains network security policies across a company’s infrastructure, according to AlgoSec.
Network security plans help a business protect its network, infrastructure, and data and prevent cyberattacks.

6 Steps to a Network Security Plan
- Analyze the company’s network and infrastructure
- Develop a business security plan
- Establish a network security policy
- Incident response procedures
- Enable essential security rules
- Ensuring long-term security
1. Analyze the company’s network and infrastructure
A company’s network and infrastructure contain vital business data. A company should analyze its network to see what data needs protection the most. This may include business assets and customer information.
Labeling assets by high, medium, and low importance helps an organization identify and prioritize areas where it should focus its network security efforts.
2. Develop a business security plan
A corporate cybersecurity plan can include strategy and tactics across a range of technologies, such as passwords, computers and apps, social media accounts, and Wi-Fi. All of these technologies can affect the network security and be compromised by cybercriminals. Using antivirus, security software, and assessments helps a business stay protected.
The entire organization should be aware of the security plan, including compliance, legal, and development teams, to ensure it is approved and implemented enterprise-wide.

3. Establish a network security policy
Security experts know that a company should have a written network security policy, which sets out employee and company expectations.
The policy can cover a range of topics, such as logins, password managers, and web and email usage, as well as specific security measures to protect the company’s network and data. .
4. Incident Response Procedures
Incident response helps a business deal with a cyberattack.
A company’s security team should be trained and ready to mitigate and stop cyberattacks or potential attacks.
The team should also have contingency plans for infrastructure while they work toward a resolution.
5. Enable essential security rules
A business should be prepared to identify the most critical security rules for its network. Describing the policies and controls that a company will use is a necessity for orientation and communication within the security team and the company.
Rules should include how to use security systems and how to implement cybersecurity best practices and tools.
6. Ensure long-term security
After establishing a network security plan, a business should implement ongoing, long-term security schedules, such as network security assessments, testing, and audits.
The use of diagnostic and monitoring tools is essential to ensure that network security remains up-to-date and effective as cyber threats evolve.
What components should be part of a network security plan?
Here are some of the key tools a business can use to develop a network security plan:
- Network firewall
- Intrusion Prevention System (IPS)
- Anti-virus and anti-malware software
- Vulnerability Scanning Software
