Security has always been a problem. Throughout history we have literally dedicated ourselves to finding ways to keep people from ‘getting into things’, so to speak. We invented locks to keep people out of rooms, boxes, chests, and even cars, but as technology has moved forward, so too has our need to invent more ways to ‘keep people out’. We’re speaking today on network security which is something you will learn about in our information security training courses.
There are many very important things for you to remember when you are securing a network but the most important thing to remember is that people will ALWAYS find a way in. You can do a lot of things to prevent it, from setting a password, to developing a robust firewall, but the truth, is simply that it isn’t enough anymore. Passwords used to keep people out but let’s face it, people have become smarter and with an information security degree you’re going to be able to defend systems from those with less than reputable agendas.
One of the best ways you can protect a network is with a key fob system, which is usually developed by a third party. But wait! What’s a key fob? How does it work? Where do you get it? Let’s take a look in the next section.
Key Fobs – One of the Most Important Parts of Information Security Training
Key Fobs are becoming more and more common today – perhaps more so than you actually realize. What are they exactly? Okay the first thing that we really want to point out is that key fobs can come in two different forms. Most commonly they come in the form of a smartphone app, but they can also be physical devices. Before we get into that however, we will need to discuss exactly what they do. This begins with the two-layer security system.
The First Layer – It begins with the user’s password, and all users are obviously encouraged to choose something that cannot be easily guessed. Typically you end up with a series of letters and numbers which will make it much more difficult for a brute force attack to take place. The problem, however, is that no matter how many precautions are taken with the password, there is still a good chance that it will be broken, and with that being the case, you need the second layer.
The Second Layer – The second layer of security for a user account is authentication. Once the user enters their password they will be prompted to enter a code generated by an application or device. Usually they will have a period of sixty seconds to enter that code before it becomes invalid, and once the time period has passed, the user will simply be required to generate a new code.
In the second layer of security, the key fob or application is tied directly to the user, meaning you cannot simply lift a key fob from another user and expect it to work on your account. This makes it extremely difficult, to say the least, for an intruder to gain access to your system from the outside, though there is always the possibility of a smartphone being cloned if the intruder is resourceful enough. Still, if you are trying to restrict access to local users only, key fobs really are the best way to go about it. This is just one of the many things that you will be learning in information security systems school.
