Passwords or Pass Phrase? Protecting your Intellectual Property


There has been a lot of talk about the theory of password protection of files, computer connection, and other access to the network. In the past, we used a combination of letters, special characters, and other techniques to prevent unwanted or unauthorized access to our computers, resources, and networks. A new theory of passwords is emerging, which could help us memorize our access codes, enhance our security and prevent hackers and thieves from entering. outside our networks.

A password is a combination of words, letters and special characters that only the user can know, thus allowing access to a computer or other information resources. As human beings, we have every day a large number of codes and numbers to remember, such as padlock entrances to our apartment, national identification numbers, driver's license numbers or permit, phone numbers, it is a bulky and confusing set. we must memorize.

When choosing a new password or code to access a computer system, most of us understand how difficult it is to remember complex codes. We therefore select information already known to us, such as names, anniversaries, national identifiers or others. known objects, then place a number or a character in front of the name or number, thinking that it is secure. This is easy to understand because most of us simply do not have the ability to instantly recall a lot of complex codes.

In the worst case, we simply write the complex code on a piece of paper and leave it in an office, in our wallet or, in many cases, stuck to the front of our computer screen.

However, for a hacker, this greatly facilitates access to your network or your computer. In general, they have only one knowledge to learn about you and add a few numbers to the beginning or end of your personal data – you'd be surprised how many times that gives access to computers and networks. Add some good "hacking utilities" as a result of hacker tools, and you will understand the threat.

Passwords are a concept that will help us create safer and easier-to-remember backups for the protection of our network and computing resources. A passphrase is a selection of words and / or numbers of 15 characters or more, which we remember easily. Some examples of good passphrases are:

o igotodalaieejdaily

o she has a beautiful hair

o surfinginhawaiiisgreat

According to Mark Minasi, a reputed security consultant, a 15-character passphrase requires a cracking program that includes the following number of calculations to try to break a 15-character passphrase:

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

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

As you can see, the security level of your resource is pretty good.

If you forget or lose the password and use a utility such as Microsoft's Encrypting File System (EFS), you may also lose access to your important files if you need a hard reset. of the system. Your password. All EFS encrypted files are linked to your connection profile, which means that if you encrypt a directory or file with EFS and perform a hard reset on your computer, these files and directories are lost FOREVER.

For Microsoft Windows users, you can now also use spaces in your passphrase. However, we do not recommend incorporating spaces into your passphrase, as this actually allows a hacker to more easily access your code. This could help them decipher it in 100,000 years. rather than 250,000!
