As one of the most popular information security standards, ISO 27001 certification has grown by 450% in the last ten years. Not only can it help support overall cybersecurity compliance, but it can help reduce data breaches and associated costs. At a time where cyberattacks are on the rise and ever more sophisticated, with 46% of businesses identifying breaches or attacks over last year, compliance, cyber hygiene and risk management have all become increasingly important. But what is ISO 27001 and how do organizations get certified?
What is ISO 27001?ISO 27001 is a standard that works to establish, implement, operate, monitor, review, maintain and improve an Information Security Management System (ISMS). The latest version was updated in 2013 and is open to both individuals and organizations. ISO 27001 is built around the implementation of information security controls and as such isn't deemed universally mandatory; this is because all organizations will have their own individual requirements when developing an ISMS with regards to policies, procedures, people and technology. The certification isn't provided by the ISO itself but, instead, it's performed by individual certification bodies. It forms part of the ISO 27000 series of information standards, which offers best practice guidance on information security management.
Why Is ISO 27001 Important?Not only does this standard encourage IT departments to make regular checks but also actively encourages external audits, helping organizations manage security in a consistent and cost-effective way. Additionally, from an organizational perspective, it demonstrates that you have identified risks before putting controls in place to help manage vulnerabilities and threats. With a focus on three key elements ' people, process and technology ' this ISO standard improves support risk management strategies and compliance standards including GDPR and NIS Regulations.

How Can I Achieve ISO 27001 Certification?To become ISO 27001 certified, there are 10 stages you need to go through. These include:
- Understanding the background of the qualification and what you need to do to be prepared. As part of this stage, you'll need support from the management team and a team member who will take responsibility for this process.
- Outlining your ISMS objectives including the overall cost and timeframe for carrying out any changes (this will help determine how long the process will take to complete). At this point, you'll need to decide if you require external support.
- Setting out and establishing a management standard. This will include a schedule of activity and regular auditing to support the continuous improvement process.
- Conducting a formal risk assessment to outline/understand where your organization is most vulnerable. Results of this must be recorded.
- Mitigating risks and making the decision as to whether you want to treat, tolerate, terminate or transfer the risks. After all, your auditor will want to review any responses made following your risk assessment with the Statement of Applicability (SoA) and Risk Treatment Plan (RTP) being mandatory requirements.
- Upskilling your team by conduct training (internally or externally). All employees will likely need to change their approach to work in some way and an explanation behind this will help to ensure employees remain compliant.
- Getting your required documents in order to support ISMS processes, policies and procedures.
- Focusing on continuous improvement because after all, the ISO 27001 certification should remain relevant as your organization evolves.
- Conducting an internal audit at regular, planned intervals.
- Receiving the results of your formal audit during Stage One, may guide potential improvements or areas on non-conformity that need to be addressed before proceeding to Stage Two. During Stage Two ' the registration audit ' an auditor will perform an assessment to determine if you are compliant with the standard.
