Network Security

 

Businesses of all sizes now connect to the Internet to conduct their business. Not only, then, do they need Internet access to check e-mail or surf the Web, they also need Internet access to check their suppliers' and/or customers' databases for information pertaining to their operations. As these "internal" networks are exposed to the Internet, the risks of hackers compromising internal computers, servers, and information rise. Further, as these servers are used to provide e-mail and other web services internally and externally, these risks rise exponentially.

 

Companies mistakenly think that the basic routers and firewalls widely available in electronics stores are adequate to protect their internal networks. That, however, is far from the truth; many companies realize that basic routers and firewalls are inadequate only after a security exposure occurs. And, by that time, it may just be too late to do anything about it!

 

To effectively secure internal networks, companies need to be proactive in managing their security. Industry-standard firewalls, although expensive, do a much better job of protecting internal networks and providing secure access to web services. Further, they allow secure access to internal servers for employees who telecommute or are in the field to provide customer service or support. The risks of not using such "robust" firewalls far exceed the costs of deploying them. Yet, technology is not a panacea for security problems. A comprehensive security program that addresses both technical and managerial issues has to be in place for companies to adequately secure their networks. Remember, higher security does not equate to zero (0) security exposures; it only reduces the probability that such exposures will occur.
