Much has been said about the theory of password protection for files, computer login and other network access. In the past, we used a combination of letters, special characters, and other techniques to try to prevent unwanted or unauthorized access to our computers, resources, and networks. A new theory about passwords is emerging that can help us remember our access codes, be more secure, and generally keep hackers and thieves out of our networks.

A password is a combination of words, letters and special characters that only the user knows and that allows access to a computer or other information resources. As human beings, we have a plethora of codes and numbers that we need to remember every day, such as the key lock at our apartment entrances, national identification numbers, car license plate numbers, phone, it’s a big and confusing set of items. we have to memorize.

When selecting a new password or access code to access a computer system, most of us understand how difficult it is to remember complex codes and therefore select something that we already know, such as names, birthdays, national identifiers or others. familiar items and then place a number or character in front of the name or number thinking it is safe. This is easy to understand, as most of us simply don’t have the ability to instantly remember a large number of complex codes.

At worst, we simply write the complex code on a piece of paper and leave it on a desk, in our pocket, or, in many cases, taped to the front of our computer monitor.

However, for a hacker, this makes access to your network or computer much easier, since they usually only have to learn a couple of things about you and add a few numbers to the beginning or end of your personal details. this grants access to computers and networks. Add some good “decryption utilities” to the hacker’s toolkit and you’ll be able to understand the threat.

PassPhrases is a concept that will help us create more secure and easy-to-remember security measures to protect our computer and network resources. A passphrase is a selection of words and/or numbers that are 15 characters or more and are easy for us to remember. A couple of examples of a good passphrase are:

or igotodalaieejdaily

oh she has beautiful hair

or surfinginhawaiiisgreat

According to Mark Minasi, a leading security consultant, a 15-character passphrase will require a cracking program with the following number of calculations to attempt to crack a 15-character passphrase:

o 15 lowercase = 1,677,259,342,285,725,925,376 possibilities

o Try a million per second, it will take 531,855 centuries/years to crack the code

As you can see, this is a pretty good level of security for your resource.

Another concern with passwords is that if you forget or lose your password and you’re using a utility like Microsoft’s Encrypting File System (EFS), you risk losing all access to your important files if you need a hard reset of your computer. password. All files encrypted with EFS are tied to your login profile, which means that if you encrypt a file or directory with EFS and reboot your computer’s hardware, those files and directories will be lost FOREVER.

For Microsoft Windows users, you can now also use spaces within your passphrase, however we would not recommend embedding spaces in your passphrase as that actually allows a cracker better access to get your code; can help them figure it out in 100,000 years. instead of 250,000!
