Request Description

How does logical security differ from physical security? Discuss real-world examples from current events that fall within your assigned category with your assigned group. Post your example to the DQ 2 thread in the Main newsgroup. Discuss with the class how the posted events could have been prevented.

 

 

 

Group 3 – Discuss BOTH of the following categories.

Biological:virus, bacteria, infestations of animals or insects.

Human:strikes, sabotage, terrorism, and war.

 

Logical security is like a password protection or a firewall that is used to block information from being accessed or viewed.  For example:  The banking industry uses an encryption method.  Users are not allowed or capable of sending important and confidential information to email addresses that are outside the network.  If one tries to send confidential information outside of the network, the network will reject the delivery.  This is considered to be a form of logical security

Physical security on the other hand is very similar to the way it sounds.  One can see physical security as being something that is done physically to a network such as stealing a server or moving a computer to a different location.  Having the server locked in a closet room with locks is also considered physical security.

Biologically, a myriad of incidences can occur that will harm or destroy information systems.  For example, natural disasters can occur and destroy a network in a matter of seconds.  Protecting information from natural disasters can be completed by taking advantage of online back-up systems.  Websites now offer back-up services via the Internet for a small annual fee.

Human interference with security can involve something as simple as a break-in and theft of computer equipment and saved information.  Installing proper surveillance equipment, security alarms, and security guards can all deter such break-ins from occurring.  Similarly, password protecting computers is a way to prevent thieves from accessing information from stolen equipment.
