Security Assessments for Small Business: What to Check and How Often
Why Security Assessments Matter
Small businesses often assume they're too small to be targeted. In reality, small businesses are attractive targets precisely because they typically have weaker security than larger organisations.
Regular security assessments help identify vulnerabilities before they're exploited. They don't need to be complex or expensive—systematic attention to key areas provides significant protection.
Key Assessment Areas
User Account Security
User accounts are the primary target for most attacks.
What to check:
- Are all accounts using strong, unique passwords?
- Is multi-factor authentication enabled where available?
- Are there any unused accounts that should be disabled?
- Do account permissions match current roles?
- When did password resets last occur?
Software and Patching
Unpatched software is a major vulnerability.
What to check:
- Are operating systems current and receiving updates?
- Is business software up to date?
- Are web browsers current?
- Is security software installed and updated?
- Are there any end-of-life systems no longer receiving updates?
Backup Status
Backups are your last line of defence against data loss and ransomware.
What to check:
- Are backups running successfully?
- What data is being backed up?
- How long would recovery take?
- When was backup recovery last tested?
- Are backups protected from ransomware (offline or immutable)?
Email Security
Email is the primary attack vector for most businesses.
What to check:
- Is email protected by spam and malware filtering?
- Are staff aware of phishing risks?
- Is email encryption used for sensitive information?
- Are email authentication protocols (SPF, DKIM, DMARC) configured?
- Who has access to shared mailboxes?
Network Security
Your network is the foundation of your technology security.
What to check:
- Is the router/firewall properly configured?
- Is the Wi-Fi network secured?
- Is there separation between business and guest networks?
- Are remote access methods secure?
- What devices are connected to the network?
Physical Security
Physical access enables technical attacks.
What to check:
- Are servers and network equipment physically secure?
- Are workstations in unsecured areas locked when unattended?
- Who has keys/access to premises?
- How are old devices disposed of?
- Are visitors supervised?
Data Handling
How data is managed affects both security and compliance.
What to check:
- What sensitive data does the business hold?
- Who has access to sensitive data?
- How is sensitive data protected?
- How long is data retained?
- How is data securely disposed of?
Creating a Security Assessment Checklist
Document your assessment in a simple checklist:
For each area: 1. What specifically will you check? 2. What is the acceptable standard? 3. Who is responsible? 4. When will it be checked? 5. What happens if issues are found?
Having a written process ensures consistency and accountability.

Acting on Findings
Assessment is pointless without action:
When to Get External Help
Internal assessments have value but also limitations:
External assessments help when:
- You lack internal expertise
- Fresh perspective is needed
- Compliance requires independent assessment
- Higher assurance is required
- Vulnerability scanning services
- Penetration testing
- Compliance audits
- General security assessments
Building a Security Culture
Technical assessments matter, but culture matters more:
