We Do Not Have a Security Policy

The reality is that not every company has a security policy set (yet), and although it is important, you can still secure your network without one. Presume that you have a firewall already in place and functional. The best advice is to slowly start the process of implementing security in your network. This means carefully reviewing the business needs (very important) of each rule that you currently have in your firewall and writing down each need. Documenting why something was done will be helpful later if there is a security incident or when the network changes, providing justification on removing the entry. Certainly this advice is also true for anything new that needs to be accessed; you can plan on new things given the ever-forward marching of technology. If this book helps you keep your business and family safer, you have done something to be proud of...now go write those security policies!
