Security Threats in the Real World


A problem troubling security experts these days is that the capabilities of computers, networks, and the software controlling them has grown to the point that no single person is capable of knowing everything that needs to be done to protect all computers on a network—despite advances in security technology and tools such as firewalls, smart network routers, proxy servers, and Web- server security features. In fact, the rapid and enormous growth in the availability of security tools and technologies has exacerbated the problem. Security policies are a big part of the solution because they can direct individuals to the most effective use of the tools and technologies available. Corporate and government security policies are necessary to help enforce good security practices for the business or government entity the policies are designed to protect. In addition, security policies meet the critical need of educating government and business security personnel as to the best practices for securing business or government information systems.

As business and government networks expand to provide (external) Internet access for employees, suppliers, and customers, the expanded network environment will require that they re-evaluate security policies traditionally focused on protecting information assets from internal network threats. Although internal network threats—namely internal employees, contractors, and infiltrators seeking to steal information—continue to pose a significant threat, the Internet provides a conduit for new attacks, such as DoS attacks, to be launched.

In many cases, businesses and governments are learning security lessons the hard way as they rush to put new information systems in place or expose existing systems to the Internet. The pressure to deliver new capabilities works in favor of the attacker, because security policies are not sufficiently updated in advance to account for the additional security risk posed by new information or an existing information system being exposed in a whole new way.
