Although you lock your front door at night, how long has it been since you checked your key holders and checked the integrity of the back window? Your physical and electronic safety deserves the same type of routine check. A security audit is just a structured evaluation of how your company looks after its data, assets, and employees, which can easily be done even without hiring professionals.
In this guide, you will find a few steps on how to conduct a simple audit, which can be performed in a small or medium company within a few days.
Why Run a Security Audit?
Small companies have become appealing prey due to their generally weaker security than larger firms. A phishing email, an unprotected laptop, or an ex-employee who still has access can mean that data is ripped off, downtime ensues, and recovery costs are incurred. A regular audit helps you:
- Spot vulnerabilities before they are exploited by malicious attackers
- Comply with the law and assure clients that data is safe
- Make clients and partners trust you more
- Allocate your security budget effectively
Step 1: Define the Scope and Goals
Begin by determining what it is that you’ll be auditing. For your first attempt, try to keep it simple: the devices you use, the accounts you hold, your network, the most important software you use, and any physical locations where business data may be stored. Note down what “secure” means to your business. Are you most worried about customer information, financial records, or ensuring that your operations run smoothly?
Allocate one specific person to be responsible for the audit and set a deadline for completing it. An audit that does not have an owner is unlikely to be finished.
Step 2: Take Inventory of Your Assets
It is not possible to protect things that you cannot identify. Start by making a straightforward spreadsheet listing:
Hardware: such as laptops, phones, servers, routers, printers, and flash drives
Software: Such as operating systems, business applications, and cloud services and browser plug-ins
Data: like customer data, employee data, financial files and their storage
Accounts: determining who has access to various things
Make sure to highlight the most critical items. Anything that contains private information or ensures the company’s operation has to be placed on top of the list.
Step 3: Examine Your Backups and Recovery Plan
Backups are essentially your safety net against ransomware, hardware failures, and human mistakes. You should ensure the following:
- Your vital data gets automatically and regularly backed up.
- You practice the 3-2-1 principle: three copies of the same information on different types of mediums, one copy stored online.
- At least one copy is kept in a way that it isn’t physically reachable by ransomware.
- You have confirmed that you performed a restore. A backup that you never restored is merely a hope.
You also have a written incident response plan in place with contact details, procedures, and notification methods.
Step 4: Don't Forget Physical Security
An unlocked door could render digital protection useless. Inspect the areas around you to find out:
- Are server rooms, network devices, and filing closets secured?
- Who has access codes, keys, or access cards, and is this list accurate?
- Do people lock their computers when they leave, and do they shred confidential documents?
- Are guests signed in and monitored?
Step 5: Evaluate Vendors and Third Parties
Your security relies heavily on the services you use. Make a list of the vendors who interact with your data, including cloud services, payment processors, and IT solution providers. Inquire about their security measures, such as using multi-factor authentication and encryption, and how they handle breach notifications. Close the accounts for any vendors you have stopped using.
Step 6: Document, Prioritize, and Fix
Document each finding as you go through each area. Rank the problems in order of risk, focusing on the probability of their occurrence and damage caused by them.
Such an approach could be:
High priority: No MFA on e-mails, no backups, and no updates in critical systems. These must be done right away.
Medium priority: Old policies, too many rights and misses in training. These must be handled in a few weeks.
Low priority: Minor issues and housekeeping chores. These should go to the to-do list.
Make people accountable for each of the fixes so that results will be achieved instead of being forgotten.
Step 7: Make It a Habit
The implemented security measures are not enough for keeping secure. Various risks occur, employees come and leave, and new instruments are introduced. Perform a basic security check every year and always check quickly when there are any important changes like implementing a new system, changing the location of an office, or firing staff. Keep track of changes in the security level.
Final Thoughts
You don’t need to spend a fortune or have a lot of technical knowledge for a basic security audit. What you do need is curiosity, a checklist, and the discipline to execute it. Taking stock of what you have, tightening access, protecting data, and training staff will allow you to significantly reduce your risks and give your company a solid foundation for growth.
In case of a more complex environment, or if your company works with regulated data that involves, for example, payment cards or medical files, it is advisable to involve a professional to complete your internal review. However, in the case of most small businesses, the best time to do it is now, with the actions outlined above.
