The Network Security Basics You Need to Know

When is a computer completely safe from potential threats?  When it’s completely disconnected and unplugged from the world.  That’s today’s reality and it isn’t practical for anyone.  That’s why all of the network security basics on this list were created — to prevent a computer attack from happening and to keep them from becoming a much bigger threat if they do. Let’s take a look at the heroes of everyday network security.


Think of them as your first line of defense — a barrier that surrounds your entire network, keeping the intruders out. While they may not prevent every type of attack, they’re great deterrents and can often identify issues before they become more serious.


Sometimes new threats can expose vulnerabilities in certain types of software. That’s why Microsoft, Cisco and other companies release regular patches and updates. Patches and updates are often crucial to your network’s self-defense plan, so you’ll want to make sure your IT team stays on top of them.


Maybe your business or IT provider has a Network Operational Center, or a sophisticated help desk solution. But if they aren’t looking at trends or user behavior, they won’t be as effective.  Trends, like regular outages or users who set off frequent alerts  and red flags, could signify that larger issues are at play.


It’s that extra step that provides an extra layer of protection for your data. It ensures that only the people you authorize can actually read your data, even as you send it across the Internet, back it up on a server or carry it around in your pocket.


All it takes is one phone call or email to put your company at risk so you’ll want to educate your employees about your company’s security policies early and often.  Tell them what to watch out for and how to handle potential threats so they know what to do when the time comes.


Disasters come in many forms — hurricanes, fires, floods, data breaches and malware attacks.  If you don’t have a plan when the unexpected happens, you could lose your business.  No matter what happens, you want to make sure you can restore your IT environment to its previous state and continue vital business operations during the recovery process.
