Which of the following is not considered to be a part of active sniffing?

  1. MAC Flooding
  2. ARP Spoofing
  3. SMAC Fueling
  4. MAC Duplicating

Answer(s): C



One of the most common and the best way of cracking RSA encryption is to being to derive the two prime numbers, which are used in the RSA PKI mathematical process. If the two numbers p and q are discovered through a _________________ process, then the private key can be derived.

  1. Factorization
  2. Prime Detection
  3. Hashing
  4. Brute-forcing

Answer(s): A

Explanation:

In April 1994, an international cooperative group of mathematicians and computer scientists solved a 17-year-old challenge problem, the factoring of a 129-digit number, called RSA-129, into two primes.
That is,
RSA-129 =

When writing shellcodes, you must avoid _________________ because these will end the string.

  1. Null Bytes
  2. Root Bytes
  3. Char Bytes
  4. Unicode Bytes

Answer(s): A

Explanation:

The null character (also null terminator) is a character with the value zero, present in the ASCII and Unicode character sets, and available in nearly all mainstream programming languages. The original meaning of this character was like NOP — when sent to a printer or a terminal, it does nothing (some terminals, however, incorrectly display it as space). Strings ending in a null character are said to be null-terminated.



On wireless networks, SSID is used to identify the network. Why are SSID not considered to be a good security mechanism to protect a wireless networks?

  1. The SSID is only 32 bits in length.
  2. The SSID is transmitted in clear text.
  3. The SSID is the same as the MAC address for all vendors.
  4. The SSID is to identify a station, not a network.

Answer(s): B

Explanation:

The SSID IS constructed to identify a network, it IS NOT the same as the MAC address and SSID’s consists of a maximum of 32 alphanumeric characters.
