Specifying access control for a server room
Concentrated, business-critical equipment in a single small space makes server rooms a target for both deliberate sabotage and simple unauthorised tampering that can cause disproportionate disruption. This page sets out what a Hempstead server room should be asking for, and where access audit trail systems fit into it.
- Sector: server rooms
- Lead service: access control
- Exposure: Continuous exposure, since server rooms typically operate around the clock regardless of the wider building's hours.
Primary risk
Concentrated, business-critical equipment in a single small space makes server rooms a target for both deliberate sabotage and simple unauthorised tampering that can cause disproportionate disruption.
First priority
Access control with individually logged credentials
Common pitfall
Fitting a keypad with a single shared code that everyone in the building knows, which removes any real accountability from the access control system.
Reading the risk honestly
Concentrated, business-critical equipment in a single small space makes server rooms a target for both deliberate sabotage and simple unauthorised tampering that can cause disproportionate disruption.
Exposure window: Continuous exposure, since server rooms typically operate around the clock regardless of the wider building's hours.
The role of access audit trail systems
The reporting layer of an access control system that records every credential use, door event and administrator change into a searchable history, used to answer who went where and when.
- Larger organisations with delegated administrators needing accountability for permission changes
- Sites with a compliance or insurance requirement to demonstrate access history
What we would put in first, and why
- Access control with individually logged credentials
- A shared key gives no accountability; an auditable log of who entered and when is what most information security policies actually require.
- Environmental monitoring for temperature and humidity
- Server rooms are as vulnerable to environmental failure as to intrusion, and both can cause equally serious disruption.
What that approach will not do
Better to hear this before the order than after a claim.
- Retained log data has to be managed under data protection obligations, particularly where it identifies individuals.
The obligation behind the specification
This is an obligation that changes the specification for server rooms, not an optional extra.
- Many organisations' own information security policies specify restricted, auditable access to server and comms rooms
The other route
- CCTV correlated with door events
- Visual confirmation of who actually used a credential is needed, not just the credential record.
What usually goes wrong first time
Fitting a keypad with a single shared code that everyone in the building knows, which removes any real accountability from the access control system.
The support call this sector makes most: new CCTV equipment not compatible with existing analogue cabling
Once a system has been in a while, understand why a CCTV upgrade is not working with existing cables is a common reason for a server room to ring.
Usually it comes down to power supply mismatch, newer cameras sometimes have different voltage or current requirements from the equipment they are replacing.
Before booking anyone, check the age and quality of existing cabling against the new equipment's requirements.
Local notes for Hempstead
Property around Hempstead Valley Shopping Centre is largely 1970s estates and newer Hempstead Valley housing, which is worth saying on the phone so we arrive with the right access equipment.
