Understanding who accesses your business systems is essential for protecting your data and maintaining smooth operations. Monitoring access means keeping track of which employees or third parties log into your computers, networks, or cloud services, when they do so, and what actions they perform. This visibility helps you spot unusual activity early, prevent unauthorised access, and meet data protection requirements.
Why monitoring access matters for UK SMEs
Without clear records of system access, your business risks data breaches, accidental or deliberate misuse of information, and operational downtime. For example, if an ex-employee still has access to your systems, they could unintentionally or maliciously cause harm. This can lead to lost productivity, damage to your reputation, and potential fines under UK GDPR or the Data Protection Act 2018. Additionally, many compliance frameworks like Cyber Essentials and ISO 27001 require businesses to maintain audit logs and control access effectively.
A typical scenario
Consider a mid-sized UK company with around 100 staff using a mix of on-premise servers and cloud applications. They noticed some sensitive files were accessed outside normal working hours. Their managed IT provider helped them implement centralised access logging and set up alerts for unusual logins. This allowed them to quickly identify a compromised account and prevent further data exposure. The provider also helped review and tighten user permissions, ensuring staff only had access to what they needed.
Practical checklist: How to monitor system access effectively
- Ask your IT provider: Do you maintain detailed access logs for all critical systems? Can you provide regular reports or alerts on unusual access patterns?
- Review access control policies: Are user permissions regularly reviewed and adjusted? Is multi-factor authentication (MFA) enforced for all system access?
- Check internal controls: Can you access a list of who has access to which systems and when they last logged in? Are shared or generic accounts avoided?
- Ensure logging is comprehensive: Are logs stored securely and retained according to compliance needs? Are they protected against tampering?
- Test incident response: Does your provider have a clear process to investigate and respond to suspicious access events?
Next steps
Monitoring access is a foundational part of cybersecurity and compliance for UK SMEs. If you're unsure about your current visibility or controls, discuss your needs with a trusted managed IT provider or IT advisor.
