The experts compared the reliability of the three types of passwords

Expert Computer Laboratory at Cambridge University Ross Anderson in his book "Security Engineering 2nd Edition" described a study of passwords for their reliability.

The experts decided to establish what passwords (invented by users, randomly generated or compiled on the basis of passphrases) are the most reliable.

The experiment involved 300 students. The volunteers were divided into three groups ("red", "yellow" and "green") one hundred people each. Participants in the "red" team independently came up with a password consisting of 8 characters, at least one of which is not a letter. Students from the "yellow" group came up with a password consisting of the first letters and punctuation known phrases or sayings (such as a password «Wyc-swyg» turned out «What you see is what you get»). "Green" group received one hundred randomly generated passwords. Participants had to memorize them and destroy them.

Hackers compromised a large number of Twitter users passwords

The Social Network did not provide details on the causes of cracking and its initiators.

The administration of the social network Twitter has sent letters to thousands of users with e-mail notification about breaking their account by third parties. Some accounts were actually compromised, but the others were notified after Twitter inadvertently reset.

It should be noted that at the present time, representatives of the social network refused to provide any data on the causes of break-ins, as well as those responsible for it.

In a statement Twitter states: "If we believe that your account has been compromised, we reset the password and send a notice to the owner account ... This is our normal job, which is to provide reliable protection to users."
