November 3, October 12, September 15, September 14, That lets them identify particular approaches — accessing specific files or running certain programs — that can give them increasing control over the machine and its data. In recent years, attackers began targeting web browsers, which are allowed to connect to the internet and often to run small programs; they have many vulnerabilities that can be exploited.

Those initial openings can give an attacker control of a target computer, which in turn can be used as a point of intrusion into a larger sensitive network. Sometimes the vulnerabilities are discovered by the software developers themselves, or users or researchers who alert the company that a fix is needed. As a result, the software or hardware has been compromised until a patch or fix can be created and distributed to users.

The best way users can protect themselves is to regularly install software updates , as soon as updates are available. Edition: Available editions Global. Become an author Sign up as a reader Sign in. BeeBright via shutterstock. Thomas Holt , Michigan State University.

And your computer knows how to interact with most of them. Click on an image file, your computer opens up an application that works with images. Click on a link to a website, your computer will open up a web browser what is a web browser? That other computer, called a server What is a server? Pretty neat. However, it is still just a bunch of files, only this time they were sent to you over the internet.

Okay, so your computer is just a bunch of files. But what is actually going into these files? A programming language is just a bunch of text that can be translated into a set of operations that your computer knows what to do with. And know that some person, somewhere, had to write all of that text.

The compiler takes this text, and turns it into a bunch of instructions that your computer can run, and shoves those instructions into a file or a bunch of files. That is really all your computer does, all day long.

It just sits there opening up file after file, reading out instructions and running them one after another over and over and over. All day, every day. I know, I know, bear with me. We are getting closer. And our computer just goes through these files executing the instructions. The instructions are actually even more fundamental than that, but I think you get the idea. These instructions are incredibly basic, and it takes a TON of these instructions for applications to do anything.

These instructions have to be really simple, because that way you can combine a ton of these instructions in different ways and cause your computer to do pretty much anything. This would get out of hand quickly. But instead, we have a bunch of incredibly basic instructions that we can string together to draw a red button or a green button.

These very simple instructions would cause the computer to draw, pixel by pixel what in the world is a pixel? In order to produce all of these instructions, we need a lot of code. Your computer is pretty dumb, it just sits there all day running instructions. You are typing in an address for www. Many thousands of things.

Everything from interpreting the keystrokes from your keyboard to drawing the letters on your screen to making requests across the internet to Google. But each of those actions is made up of many hundreds of thousands of very simple instructions. It is so complicated that it is hard to wrap your mind around it. This is not a simple thing to implement. It requires some planning, a certificate authority. You need certificates put on your web servers, but that hard work is going to result in a very secure channel between the devices on your network.

This in the clear information is so easy to gather, especially on wireless networks. Those credentials have to be stored somewhere. Generally, the username is stored in plain text. My name will be there and readable in that database, but the password will not. Ideally, the password is never going to be stored in plain text. Having the salt in place makes it harder for somebody to perform a brute force against that hash to determine what the password might be.

Then you know that particular password is insecure. A secure password reset would send you a link into your email that then takes you back to that service to update and change your password information. A plain text password should never be sent over any electronic medium. For example, a communication protocol that you would not want to use over network is this relatively old SLIP, or serial line interface protocol.

If you want an example of a more modern protocol you should not be using, then you can see Telnet is a good example.
