A useful guide for small and medium-sized businesses on how to do an ISO 27001 security assessment
In today’s business world, where everything is linked, information security isn’t just a problem for big companies. Cyberattacks and data breaches are happening more and more to small and medium-sized businesses (SMEs). A security review is a very important part of putting the ISO 27001 standard into practice because it gives a strong basis for handling information security. SMEs can use this piece as a useful help to do an ISO 27001 security review that fits their specific needs and available resources.

Choose a Security Champion:
Pick someone on the team to be in charge of the security review. This doesn’t have to be a full-time job, but the person should know a lot about the business and how it works.
Explain the scope:
Make it clear what parts of your business the ISMS will protect. For small and medium-sized businesses, this usually means the whole company, but you could start with the most important parts and add to them later.
Divide up the resources:
Figure out how much money and people will be spent on the security review. Be honest with yourself about what you can do with the tools you have.
Teach Your Staff:
Give everyone on staff basic training in information security knowledge. This makes the review process go more smoothly and helps build a mindset that cares about security.
Performing the Security Assessment for ISO 27001
Step 1: Make a list of your assets
Make a list of all the information sources that fall within the area you set. Among these are:
Hardware includes computers, servers, and smart phones.
Applications for software
Data includes things like bank records, customer information, and intellectual property.
Assets that can be seen and touched
Human resources (skills and knowledge)
Write down who owns each item, where it is, and how important it is to the business.
Step 2: Look at the risks
Find possible threats to your assets and weak spots in them:
Collaborate on ideas with important staff members.
Take both internal and foreign threats into account.
Don’t forget about risks to people and the world.
Think about how likely each risk is to happen and what effects it might have. For SMEs, a simple score system like “High,” “Medium,” and “Low” is often enough.
Step 3: Choose a control
Choose the right controls from ISO 27001 Annex A based on your risk estimate. Pay attention to your biggest risks first. Keep in mind that not all rules will work for your business.
Controls that SMEs often use are:
Rules for controlling access
Software changes and patch handling on a regular basis
Protect against malware
How to back up and restore data
Measures for physical security
Employee teaching on security knowledge
Step 4: Look for gaps
Check how your current security measures compare to the ISO 27001 standards and the controls you chose. Figure out what you’re doing wrong.
Step 5: Make a plan for how to carry out the plan
Make a plan to fill in the gaps that you’ve found:
Sort acts by how dangerous they are and how many resources are available.
Set reasonable due dates
Give defined tasks to different team members.
Think about quick wins to get things going.
Step 6: Keep records
Make or change the appropriate paperwork, such as:
Statement of Applicability (SoA) for the Information Security Policy Risk Assessment and Treatment Plan Security rules and instructions
Keep paperwork short and focused on how it can be used in real life.
Step 7: Do an internal audit
To make sure your ISMS is running as it should, do an easy internal audit:
Check the paperwork to make sure it’s full.
Make sure the tools are set up the way they were described.
Find any problems or places where things could be better.
Step 8: A review by management
Tell managers what the results of your security check are:
List the most important results and risks
Outline the suggested changes and resources that will be needed.
Make sure the next steps are okay.
Always Getting Better
Keep in mind that following ISO 27001 is an ongoing process, not a one-time thing. Set up a circle of constant improvement:
Regular tracking: To make sure limits keep working, set up simple tracking procedures.
Incident Management: Make a simple plan for how to handle incidents and urge people to report security events.
Periodic Reassessment: Review your risk assessment and the efficiency of your controls once a year.
Keep up with:
Make sure you know about new risks and the best ways to keep your business safe.

Using technology to check the security of small businesses
You might not be able to get enterprise-level security tools for small businesses, but there are a lot of low-cost technologies that can help with the security review process:
Cloud-based Security Services: For tasks like email blocking, web safety, and data backup, use cloud security solutions.
Open-source security tools: Look into free, open-source tools that can scan for vulnerabilities, analyze logs, and keep an eye on your network.
Mobile Device Management (MDM): Start with simple MDM options to protect work-related smartphones and computers.
Password Managers: To get everyone in your company to use strong, unique passwords, use password managers.
Tools for Encryption: Scan your files and emails with encryption to keep private information safe.
Virtual Private Networks (VPNs): Protect employees who work from home who need to access company data remotely with VPNs.
Getting ready for certification (optional)
Even though it’s not required, some small and medium-sized businesses may choose to get ISO 27001 approval to stay ahead of the competition or meet client needs. If you’re thinking about certification:
Do a Pre-assessment: Carefully look over your ISMS against all of ISO 27001’s criteria.
Take care of non-conformities:
Fix any problems you found in the pre-assessment.
