Wireless networks are more vulnerable to hackers - so they need additional protection.
Encryption technologies such as Wi-Fi Protected Access can help. Although there are weaknesses with WEP, some legacy systems do not support more modern protocols like WPA, and so WEP is still better than nothing and will deter most casual eavesdropping.
Many security initiatives fail to have longevity.
Because they are not presented to senior management as a business need they lack the authority to be prioritized.
Patch management is the cheepest security fix available.
Having an automated patchmanagement system is straight forward to setup with almost no administrative overhead. Set it up once for your environment and it will do the work.
Email is a hackers gateway to your network.
Make sure you have adequately trained your employees in good email hygiene to reduce virus attacks.
Set up a firewall. Even if you just use dial-up or DSL you are fully exposed to the internet.
This is your primary defense and protects against outside attacks by screening and blocking all traffic between your network and the Internet that is not allowed. The firewall also hides computer addresses. Firewall hardware connects between the cable/ DSL modem and your computers. Windows operating systems have great built-in firewalls.
