Using COVID to Understand Layered Security

We can learn a lot about network security by looking at the way we are protecting ourselves from the COVID virus.  COVID has changed what we wear, to how we interact with others, to how we conduct business.  All these behaviors are designed to minimize our contact and keep us safe.  There is no one “silver bullet” that guarantees we will be spared; it takes several things that will ultimately minimize our exposure and slow the spread.

Likewise, in a computer network, there are policies and applications that can be used to minimize the likelihood of getting infected with malware.  Anti-Virus and Patching are the basics – these are used to maintain basic network hygiene.; it would be the equivalent of brushing your teeth and washing your hands after you go to the restroom — you do them no matter what.

Besides the basics, there are other layered security measures you need to put into place above and beyond – just like what we’ve done with the Coronavirus. A good network security plan has layers in it like: educating our employees how to spot and identify fraud & phishing scams, deploying SPAM control and content filtering, implement behavioral based threat protection, turning on intrusion prevention, having a password policy, testing and vetting firewalls, etc.

Just like there is no one silver bullet with COVID, there is no one thing you can do to 100% secure you your network; however, by implementing security layers, you significantly reduce the likelihood of something getting through and making your network sick.

Spending the time and money to do layered network security correctly may seem like an unnecessary expense, but you have to keep in mind the value of the data you’re protecting.  It’s likely that if your business didn’t have access to it for a period of time it would cost significantly more than the cost of decent security.  Today is the very best time to start protecting your data and your business.
