rk connectivity is generally achieved through the incorporation of redundant network connections (again, these should follow diverse paths), and hardware that is programmed to failover to a secondary path in the event of a circuit failure. For Internet connectivity, it may even be a good idea to incorporate a secondary service provider. Again, the highest priority in a disaster is the protection of people. A good business continuity and disaster recovery strategy will ensure the protection of people as well as information assets and network assets. User Education Humans are the weakest link in security, but they are also the reason a communications infrastructure exists. Many of the aforementioned 70-90% of breaches that occur from the inside result from unintended consequences of poor operator practices. Users need to know the importance of such basics as regularly changing passwords, of choosing strong passwords, and of protecting passwords. Organizations should inform users of policies that prevent loading of unauthorized software, whether unlicensed software or freeware. Organizations should make users aware of basic forms of attack SO that they can recognize them and act accordingly (the acuity to unplug a network jack can save a network). Moreover, organizations Information Security and Video Communications should inform users of how to respond when they witness suspicious activity (e.g., a suspicious Email attachment or a program that acts different from usual). Code Red and Melissa (both of which are classified as worms) are two example of malicious code that began ravaging computer systems in 1999. Melissa affected more than 100,000 computers in a matter of a few days; Code Red took minutes. Organizations could have limited or prevented damage from either through good user education. Organizations should regularly remind users of policies and guidelines through announcements from top executives because user awareness can be the best defense.
