What Goes into a System Security Plan?
Why do you need a system security plan?
A system security plan is important for six reasons. First, it can help protect your system from unauthorized access or use. Second, it can help you meet your compliance obligations. Third, it can help you recover from a security incident. Fourth, it can help you improve your system security. Fifth, it can help you manage your system security risk. Last, it can help you plan and budget for system security needs.
What goes into a system security plan?
So what goes into a system security plan? The answer depends on the specific system and the risks associated with it. However, there are 10 common elements that you will likely need to include. Let’s take a look at each one.
- Purpose of the system security plan: This section should describe the reason for creating the security plan, such as compliance with a specific regulation or protecting the system from unauthorized access.
- Asset identification: This section should list all of the assets that are covered by the security plan, such as data, systems, and networks.
- Threat assessment: This section should identify the potential threats to the system, such as hackers, malware, and disgruntled employees.
- Risk assessment: This section should identify the risks associated with each threat, such as the likelihood of an attack and the potential damage that could be caused.
- Security objectives: This section should list the specific security goals that you want to achieve, such as protecting confidential data or preventing unauthorized access.
- Controls: This section should identify the specific security controls that will be used to protect the system, such as firewalls, antivirus software, and passwords.
- Implementation plan: This section should describe how the security controls will be implemented, including timelines and responsible parties.
- Testing and review plan: This section should describe how you will test the security controls to ensure that they are working properly and how you will review them to ensure that they are still effective and up to date.
- Maintenance plan: This section should describe how you will maintain the security of the system over time, including updates to the security controls and regular reviews.
- Documentation: This section should list all of the documentation that is required as part of the security plan, such as risk assessments, security policies, and incident response plans.
This is just a basic overview of what goes into a system security plan. There is no one-size-fits-all answer, so it’s important to tailor your plan to meet the specific needs of your system. However, following these general guidelines will help you draft a plan that is both effective and compliant. If you’re not sure where to start, consider using a compliance service like NIST 800-171. NIST 800-171 can help you develop and implement a system security plan that meets the requirements of the NIST Cybersecurity Framework.
