What is the Principle of Least Privilege?

In information security, computer security, and many other areas, the Principle of Least Privilege, also referred to as the security least privilege principle or the least authority principle, states that there should be no need for you to give out any information in exchange for it. Basically, this means that if you cannot be trusted enough to give out sensitive information then it is not going to be safe to use it on a computer.

If a person is able to gain access to your computer system without the proper authority, then they have accessed your private information. Therefore, if they do not have the proper authorization, they have broken the rule of privilege. It is important to note that this does not include if they were using a password to gain access. The rule states that they should only gain access to information that you give them permission to access.

Most people agree that giving away information without a password is extremely important. In fact, if you give someone a password then they will never go back and change it because they have done it without you ever knowing. Therefore, this means that if they can gain access to the system without your permission, then they can gain access to almost any information you are holding and they will be able to use this information for their own personal gain.

This principle also applies to different ways you store your information. For example, if you store your information on a hard drive in your house then they will not be able to hack into that same system to get the information they need, but they can get access to the information on another system that is connected to your hard drive.

Therefore, the Principle of Least Privilege states that any security measures that you have put in place should only be used when it is absolutely necessary. This means that if your company only uses one security measure for all of your computers, then there is no need to give out sensitive information or passwords to anyone that does not have a legitimate reason to do so. This also holds true with websites that store sensitive information online.

If you think that your system will be too complicated or that you would have to spend hours doing it yourself then you may want to consider hiring a professional. However, there are some companies that are available that will install and secure your system for you for a low cost. However, they will not be able to guarantee the protection that a full service would offer. If you want absolute security then you may want to take the time to learn about the many different security measures available, including the ones that are available online, before you decide on the best one for your needs.
