Q234. In the context of password security, a simple dictionary attack involves loading a dictionary file (a text file full of dictionary words) into a cracking application such as L0phtCrack or John the Ripper, and running it against user accounts located by the application.

It usually tries every possible letter and number combination in its automated exploration.
If you would use both brute force and dictionary methods combined together to have variation of words, what would you call such an attack?
A. Full Blown
B. Thorough
C. Hybrid
D. BruteDics

A. Yes. June can use an antivirus program since it compares the parity bit of executable files to the database of known check sum counts and it is effective on a polymorphic virus
B. Yes. June can use an antivirus program since it compares the signatures of executable files to the database of known viral signatures and it is very effective against a polymorphic virus
C. No. June can't use an antivirus program since it compares the signatures of executable files to the database of known viral signatures and in the case the polymorphic viruses cannot be detected by a signature-based anti-virus program
D. No. June can't use an antivirus program since it compares the size of executable files to the database of known viral signatures and it is effective on a polymorphic virus

Q236. The GET method should never be used when sensitive data such as credit card is being sent to a CGI program. This is because any GET command will appear in the URL, and will be logged by any servers. For example, let's say that you've entered your credit card information into a form that uses the GET method. The URL may appear like this:
https://www.xsecurity-bank.com/creditcard.asp?cardnumber=453453433532234
The GET method appends the credit card number to the URL. This means that anyone with access to a server log will be able to obtain this information. How would you protect from this type of attack?
A. Never include sensitive information in a script
B. Use HTTPS SSLv3 to send the data instead of plain HTTPS
C. Replace the GET with POST method when sending data
D. Encrypt the data before you send using GET method
