When reviewing an organization's logical access security to its remote systems, which of the following would be of GREATEST concern to an IS auditor? - ANSWERSUnencrypted passwords are used. When evaluating the technical aspects of logical security, unencrypted passwords represent the greatest risk because it would be assumed that remote access would be over an untrusted network where passwords could be discovered. Which of the following would be the BEST access control procedure? - ANS...

What is the block and output size of SHA1? 1 512-bit blocks with an output of 128 bits 2 512-bit blocks with an output of 160 bits 3 1024-bit blocks with an output of 256 bits 4 1088-bit blocks with an output of 256 bits - Answer- 2 The SHA1 (Secure Hash Algorithm) 1 hashing algorithm operates on one 512-bit block at a time and outputs a 160-bit hash function, usually represented as a 40 hexadecimal digits. This value can be used to validate the integrity of the data. It crea...
