Answer 44

Directory traversal Directory traversal attempts to read or access files outside the scope of the web server's file directory. The pair of dots in a file path (..) refers to the parent directory, so this example is attempt to move back two parent directories before proceeding into the /Windows directory. In a properly configured web server, this traversal should not be possible.

Question 45

A developer has created an application to store password information in a database. Which BEST describes a way of protecting these credentials by adding random data to the password?

Answer 45

Salting Passwords are often stored as hashes, but the hashes themselves are often subject to brute force or rainbow table attacks. It’s common to add some additional random data (a salt) to a password before the hashing process. This ensures that each password is truly random when stored, and it makes it more difficult for an attacker to discover all of the stored passwords.
