Physical Network Security For Dummies

Physical Network Security For Dummies

When it comes to Internet security, many businesses and organizations put in place a broad range of measures. They do so to limit and block any hacking attempts by outside entities, and to ensure the security and privacy of their data.

Some of those measures will include things like firewalls, restricted IP address access, and user access control (i.e. usernames and passwords). The thing is, a surprising amount of companies and non-commercial entities seldom think about physical security!

As you can appreciate, online security is just one way of ensuring that your data doesn’t fall into the wrong hands. The other is to prevent unauthorized people from having direct physical access to your computers and servers. So, how can you ensure that random people in your building don’t have easy access to your network infrastructure?

The good news is that it’s easier than you think to physically secure your network and prevent data theft. Here are a few typical examples of what you can do:

Physical access control systems

Arguably the first and most important thing you need to do is only allow authorized personnel access to your networking equipment. To do that, you must put in place some physical access control measures.

You might think that a simple lock and key solution will suffice for your needs. But, you need to make it hard or even impossible for would-be data thieves to get into your server or network rooms.

These days, many businesses and organizations look towards technology for help. Examples include biometric systems, such as fingerprint or retina scan validation. While there are many “off the shelf” solutions you can implement, if you have highly sensitive data at your premises, it makes sense to consider a custom solution for your needs.

In a nutshell, this is where you have the entire system designed and built from scratch according to your precise specifications. We’re talking about doing everything here, from keypad membrane switch manufacture through to access control software programming!

Security monitoring

It’s likely that you will have networking equipment that runs 24/7 and even has a backup power supply solution. Of course, you can’t be at your premises all day, every day! With that in mind, it’s a good idea to have teams of security personnel monitoring or “guarding” your networking equipment.

They can also keep a log of who goes in or out of your server rooms, and alert you to any problems such as potential break-ins. Your solution may only warrant the need for a single security guard, or a team of armed personnel if the threat of a physical attack is high.

Component segregation

You might think that it’s easier and cost-effective to just put all your network switches, routers, servers, and other kit in one room. But, from a security point of view, it could spell disaster should someone gain unauthorized physical access to your network room!

Instead, consider segregating each type of component into different areas of your premises (or even different sites). Doing so will make life harder for any would-be hacker to physically gain access to your network.
