Your network is not 100% secure, but that does not mean that you should stop trying to improve security. With cloud computing and more business activity moving online, security is more critical than ever.
The interesting thing is that a lot of people are talking about security, yet I frequently see that executives do not even know where their companies stand on security. Even if you do not have a big budget for security, it is important to understand your risks and at least take some basic (low cost) steps.
1) Understand your current security measures
Make sure you know what security measures and processes are already in place. Do you have a firewall? Is your wireless network secured? Are patches and updates being applied regularly (e.g. monthly) to your servers and computers? Are antivirus updates being applied daily (and no users have disabled antivirus for convenience)?
