Which of the following best describes session key creation in SSL?

Which of the following is NOT true of cryptography?

What is SYSKEY # of bits used for encryption?

In the context of using PKI, when Sven wishes to send a secret message to Bob, he looks up Bob’s public key in a directory, uses it to encrypt the message before sending it off. Bob then uses his private key to decrypt the message and reads it. No one listening on can decrypt the message.

Anyone can send an encrypted message to Bob but only Bob can read it. Thus, although many people may know Bob’s public key and use it to verify Bob’s signature, they cannot discover Bob’s private key and use it to forge digital signatures.

What does this principle refer to?

Steven the hacker realizes that the network administrator of company is using syskey to protect organization resources in the Windows 2000 Server. Syskey independently encrypts the hashes so that physical access to the server, tapes, or ERDs is only first step to cracking the passwords. Steven must break through the encryption used by syskey before he can attempt to brute force dictionary attacks on the hashes. Steven runs a program called "SysCracker" targeting the Windows 2000 Server machine in attempting to crack the hash used by Syskey. He needs to configure the encryption level before he can launch attach.

How many bits does Syskey use for encryption?

Symmetric encryption algorithms are known to be fast but present great challenges on the key management side. Asymmetric encryption algorithms are slow but allow communication with a remote host without having to transfer a key out of band or in person. If we combine the strength of both crypto systems where we use the symmetric algorithm to encrypt the bulk of the data and then use the asymmetric encryption system to encrypt the symmetric key, what would this type of usage be known as?

An attacker runs netcat tool to transfer a secret file between two hosts.

Machine A: netcat -1 p 1234 < secretfile

Machine B: netcat 192.168.3.4 > 1234

He is worried about information being sniffed on the network.

How would the attacker use netcat to encrypt information before transmitting it on the wire?

Jane wishes to forward X-Windows traffic to a remote host as well as POP3 traffic. She is worried that adversaries might be monitoring the communication link and could inspect captured traffic. She would line to tunnel the information to the remote end but does not have VPN capabilities to do so.

Which of the following tools can she use to protect the link?

Which programming language is NOT vulnerable to buffer overflow attacks?

In Buffer Overflow exploit, which of the following registers gets overwritten with return address of the exploit code?
