Security is the process of preventing and detecting unauthorized use of your computer network. Prevention measures help you to stop unauthorized users (also known as "intruders") from accessing any part of your network. Detection helps you to determine whether or not someone attempted to break into your system, if they were successful, and what they may have done.
Firewall
Intruders are constantly scanning systems and networks for known vulnerabilities. Network firewalls can provide some degree of protection against these attacks. However, no firewall can detect or stop all attacks. It's not sufficient to install a firewall and then ignore all other security measures. Solid anti-virus and anti-spam solutions are necessary supplements with a firewall appliance.
Wireless
Mobility is everywhere and quickly becoming the cost effective solution for office networking. With today's technology, a wireless network is just as effective and effecient as a wired solution. There are many encryption methods to keep your data safe from outside attack. Some of the methods out there can be breached in minutes. Proper wireless network design is key to keeping your data confidential and safe from intruders.
