Explain various threats posed through servers into a client server environment.

Server Destroyed within an Accident: Power failures, Leaking pipes and equipment failures are not uncommon

Destruction of Data Alteration of Disclosure of Fraud Denial of Service

Users Logged within on Unattended Desktop Computer.

The client/server architecture removes the incentive to sign off of mainframe applications to save onto connect time charges.

Incorrectly Protected Server Accounts Used to Gain Access

Address Spoofing: Anyone spoofs network addresses to get access to servers, and uses which access to read/alter data or establish future access.

One is "spoofs" a network address through their host computer to "impersonate" a trusted computer, thus incorrectly gaining special permissions and access which only the trusted computer must have.

Sensitive Data Disclosed by Packet Sniffing.

Alter data or programs, and put down behind hidden programs that steal passwords through unsuspecting users of the system, and that make future intrusions easier.
