Network Security - "Its not what we used to think it was"
The Internet and recent world events have fundamentally changed the way
organizations approach security. Only a decade ago, network protection centered
mostly on the concept of keeping people out at all costs. Anytime an outsider
gained access to an organization's system, it was considered a serious problem.
Today, the Web and networked e-business applications, telecommuting, branch
connectivity, partner connectivity, and wireless mobility have emerged as
increasingly important tools. As a result, protecting data is paramount.
Today's companies face a myriad of network security risks: Web site vandalism,
viruses and Trojan horses, denial-of-service attacks, data destruction and
theft, and a variety of other problems. These threats can come from outsiders
or from employees, who may compromise security either intentionally or
unintentionally. According to Computer Security Institute's 2002
Computer Crime and Security Survey, 90% of respondents - mostly large
corporations and government institutions - had detected computer security
breaches within the previous 12 months. Not surprisingly, 74% cited their
Internet connection as a frequent point of attack.
Attacks are getting more sophisticated, and at the same time, much easier to
deploy. In addition, companies face potential hazards from accidents and
natural disasters. These security breaches can compromise application
availability, data confidentiality, and data integrity while presenting legal
ramifications. Perhaps most important, they interrupt business, which can lead
to enormous costs to the organization.
