The Kerberos Authentication Server might reject an AS_REQ message and instead require pre-authentication - that is, it requires the client to send a timestamp encrypted with the client key. Why does it do this? Select one: a. It must not disclose the Ticket Granting Ticket before the client has authenticated b. It is dangerous to respond to an AS_REQ message before the client has authenticated c. Responding to multiple AS_REQ messages would allow a guessed plaintext attack d. It needs the client's public key to check the pre-authentication message was signed correctly

Network Security

The word "network security" refers to a wide range of technology, devices, and processes. In its most basic form, it is a combination of rules and configurations that use both hardware and software technologies to safeguard the confidentiality, integrity, and accessibility of computer networks and data. Every company, regardless of sector, size or infrastructure, needs network security solutions to protect itself from the ever-increasing landscape of cyber threats that exist today.
