Password or passphrase? Protect your intellectual property

The theory of password protection for files, computer logins and other network access has been said a lot. In the past, we used a combination of letters, special characters, and other techniques to try to prevent unnecessary or unauthorized access to our computers, resources, and networks. A new cryptography theory is emerging that helps us remember our access code, is more secure, and often excludes hackers and thieves from our network.

A password is a combination of words, letters, and special characters that only the user knows, allowing access to a computer or other information resource. As humans, we need to remember a lot of code and numbers every day - for example, the key lock on our apartment entry, national ID number, car license or tag number, phone number - this is a huge and confusing item kit we Need to remember.

When choosing a new password or passing code to access a computer system, most of us know how difficult it is to remember complex code, so we choose what we already know, such as name, birthday, country identifier or other known items, then Place a number or character in front of the name or number to make sure it is safe. This is easy to understand because most of us simply can't call a lot of complex code right away.

In the worst case, we simply write the complicated code on a piece of paper and put it on the table, in our wallet, or in many cases on the front of our computer monitor.

However, for hackers, this makes it easier to access your network or computer because they usually only need to know something about you and add some numbers in front of or at the end of your personal data - you will often feel Surprised this granted access to computers and the network. Add some good "cracking tools" to the hacker's toolkit and you'll be aware of the threat.

PassPhrases is a concept that will help us create safer, easier-to-remember protection for our computer and network resource protection. Passphrases are choices of words and/or numbers of 15 characters or more in length and are easy to remember. A few examples of a good passphrase are:

Igotodalaieejdaily

o shehasbeautifulhair

o surfinginhawaiiisgreat

According to Mark Minasi, a well-known security consultant, a 15-character passphrase will require a cracker to count the number of attempts to break a 15-character passphrase:

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

o Try a million seconds, it takes 531,855 centuries/year to break the code

As you can see, this is a very good level of security for your resources.

Another problem with passwords is that if you forget or lose your password and are using a utility such as Microsoft's Encrypting File System [EFS], you may lose all access to important files if you need to reset your hardware. . Your password. All EFS encrypted files are linked to your login profile, which means that if you use EFS to encrypt directories or files and you perform a hardware reset on your computer, those files and directories will be lost forever.

For Microsoft Windows users, you can now also use spaces in passphrases, but we don't recommend embedding spaces in passphrases because this doesn't actually allow crackers to get the code better - this might help them in 100,000 Crack it years instead of 250,000!
