Advice is free, and here comes your money's worth... Create an action plan. Jumping right into the security conundrum without a clear picture the end result could be a big CLM. A well thought out approach could save your job. Security is the gaining of control at the cost of convenience.
Start out with a big picture "vision" of what a secure environment should look and feel like. Want to lock down every icon on the desktop, log all traffic, or do you just want to ensure that passwords are not shared, and users are aware of social engineering?
Next, talk to Supervisors and Managers about their business needs, and consider the impact that your vision would have on them.
Research ways to overcome issues and concerns. There isa product for just about everything these days, and plenty of consultants out there that can do the grunt-work and provide the expertise. Budget for it.
VERY IMPORTANT: Gain management support for anything that you do regarding security. If the big-boys aren't going to bother, then these are just 'good ideas'. Have management turn your ideas into policy.
Implement an approved step-by-step plan according to the policies and procedures that you have helped build along the way.
Once again, the concepts and outcomes should be clearly defined, like in any project. Make SMART Objectives with clear deliverables. Failing to plan is planning to fail.
As for security awareness, Tech Republic is a great source of info. Also, engageconsultants to do some presentations. Most will do this to establish a relationship with you. ISC2's website has a contact page that lists CISSP's and SSCP's that may deliver a security awareness presentation for the experience, or a nominal fee.(I know, I'm listed, and looking for work!)
