What is data centre security?
Data centre security covers a number of areas from the protection of data from external attacks to the physical access and protection of the facility and the services that it provides. At its core data centre security revolves around the protection and access to the data that it handles. Breaches in data centre security that result in stolen or lost data can result in heavy fines, loss of customers, high recovery costs and reputational damage.
What are the key data centre security issues?
There are a number of key data centre security issues that need to be considered to ensure the protection of the data stored with the data centre.
- Access To The Building – How secure is the access to the data centre itself? Could the facility be accessed by unauthorised personnel? How well controlled is the access to the data halls once inside the building? What measures are in place to track movement within the building?
- Access To Data – With increasing cyberattacks how secure is the stored data from hackers? Are firewalls, and protection software applications up to date? What about the physical security of the data? How well protected is the data from physical access at rack level?
- Data Protection – As well as the access to the data how well is the data protected in terms of privacy, and compliance to regulatory standards? In the case of hardware failures how secure is the stored data and how quickly can it be recovered?
- Redundancy – What redundancy does the data centre have to protect it from power failures, fire or natural disasters?
What data centre security tools are available?
There are a number of data centre security tools that can be applied to improve the overall security of a data centre. From the outside a low-level appearance that avoids branding the building as a data centre. Limiting the points of entry to a minimum, and where fire exits are required ensuring they only open outwards. Improving locks on doors and incorporating advanced entry systems like bio-metrics. And on the subject of doors making sure hinges are located internally to the room preventing pins from being removed. On entry to the data centre having systems in place that prevent ‘passback’ of credentials or tailgating, where someone will follow the person in front of them through the door before it closes. CCTV is a major data centre security tool, having plenty of cameras both externally and internally will play a major role as a deterrent. These can even be placed at rack level.
As well as the physical security, other data centre security tools to consider are those that prevent cyberattacks so ensuring firewalls, antivirus software, spam and spyware filters are all up to date and regularly checked.
Then there are the redundancy security tools to ensure uptime is maximised. Power systems can be protected through the use of Uninterruptable Power Supplies (UPS) and backup generators. Fire suppression systems that incorporate environmental monitoring systems and provide alerts when thresholds are breached, can help negate more serious issues.
