What Does an ISMS Include?
Investing in an Information Security Management System (ISMS) involves much more than spending on a firewall or an antivirus system. It is an integrated system of people, processes, and technology. ISO 27001 outlines several critical parts:
- Risk Assessment and Risk Treatment
- Identify internal and external risks to your information assets.
- Analyze data and assign priorities to identified risks based on their likelihood and potential impact.
- Use allocated resources to manage the most critical high-priority risks designated in the earlier step.
- Leadership and Policy
- There must be active sponsorship from senior management for the budgeting and execution of the Information Security Management System(ISMS).
- A documented information security policy requires clear articulation along with dissemination among all employees in the firm.
- Ongoing Monitoring and Improvement
- Changes that are threatening should be captured through regular reviews as well as internal audits.
- Adapt your information security policies for new business environments or make ISMS changes due to evolving threats to the business environment.
What Are ISO 27001 Controls?
The standard comprises 114 annexed controls classified into 14 control domains listed in Annex A. These controls are optional; however, you will need to provide reasoning for any of them that you include or exclude from your ISMS model.
Some examples of these control domains as they themselves span across various disciplines:
- Access Control
- Cryptography
- Physical as well as environmental security
