You are using a 56-bit encryption key called DES. Your client is concerned that this is insufficient
security. You reconfigure the VPN to use the strongest encryption used by the VPN-1/Firewall-1
software. Which of the following would you use?
A.
AES 256.
B.
Blowfish
C.
RC4
D.
CAST
E.
3DES 698
Explanation:
: The advanced encryption standard (AES) is the new FIPS publication that use US. Government
organizations to protect sensitive information. The AES algorithm is “Rijndael”. A key length of 128
to 256 bits is supported. The more bits that are added, the stronger the encryption is. This is the
strongest encryption algorithm supported by the Checkpoint NG suite. See Page 7.10 of CCSE
NG Official Courseware. (VPN1-FW1 Management II NG FP-1) .
