ISO 27001 Information Security Management Systems Increased consumer expectations of information security require organisations to implement an effective ISMS framework that preserves the confidentiality, integrity and availability of information.

Organisations and their information systems are at risk of security threats from sources including: fraud; espionage; sabotage; and natural causes. At an exciting time of global business opportunities, organisations must address these risks through a systematic approach.

We help organizations become more secured and competitive

An Information Security Management System (ISMS) is a set of rules that are designed to secure the information stored in digital form by identifying the risks to your information infrastructure. It also aims at meeting the expectations of your stakeholders by implementing controls and continually improving the Information Security Management System (ISMS) according to the changing market standards. These rules can be documented in the form of records of policies and processes or can be established with non-documented technologies.

ISO 27001 is one of the internationally recognized standards for information security management systems (ISMS). The main focus of ISMS is on information security, but cybersecurity and privacy protection also feature in its scope. An organisation’s focus to maintain its assets, repelling against cybersecurity attacks, and ensuring privacy laws can be shown by its ISO 27001 certification.

Our approach to risk and compliance Auditing

Identify risks and vulnerabilities

Next, you’ll need to determine the risks that could compromise your security. Start by taking inventory of your information assets — consider your data storage locations, any devices or hardware that can reach your data, your network, software, and so on. Then create an extensive list of potential threats; some examples could be an employee’s laptop being stolen or an office visitor accessing an employee’s password.

Analyze and prioritize risks

Now that you have a list of potential risks, determine how critical each one is to solve for and prioritize your risk treatment accordingly. This should be determined by how likely it is for this risk to occur and how severe the impact would be if it did. Go through your list of risks and determine if the likelihood is low, medium, or high for each one and do the same for each risk’s impact level. ‍

After you’ve set the likelihood and impact levels for each risk, use that information to prioritize the risks you need to address first. The risks that have both a high likelihood and a high impact ranking should be considered high-priority.

Mitigate identified risks

Next, you’ll need to use that list to take action on those risks. Look at each risk and determine ways to make it less likely to occur and reduce its impact. Identify which of the ISO 27001 Annex A controls to use to mitigate each one. Be sure to keep records of the Annex A controls you used for each risk so you can include this in your Statement of Applicability for your auditor to review.

Complete risk reports

You’ll need evidence to prove that you’ve performed your risk assessment as well since your auditor will need to verify that you’ve done this step during your audit. ‍

To ensure you have sufficient evidence, create the following reports for your auditor:

  • Risk assessment report: A report of your risk assessment process and the steps you followed, what information assets you reviewed to identify those risks, which risks you found, and the likelihood and impact ratings you gave each risk.
  • Risk summary: A shorter report explaining which risks you’ve chosen to address.
  • Risk treatment plan: A plan that includes all the risks you plan to address through your ISO 27001 compliance along with your plan for mitigating each one. ‍

    You may also want to consider starting your Statement of Applicability (SoA) at this stage as well as this document details how you’ve treated the risks you’ve identified. The SoA is a detailed report of the ISO 27001 controls you’ve implemented as a result of your assessment.

    Continually monitor and review your ISMS

    Proper risk assessment is an ongoing process, not a one-time task. Whenever there are changes to your data storage, your network, or other aspects of your operations, new risks can arise. As part of your ISO 27001 risk assessment process, create a plan to continuously monitor for new risks or any changes that could alter the likelihood or impact of known risks. ISO 27001 certification requires you to conduct a full risk assessment at least once per year, but additional routine risk assessments will help you stay secure year-round.
