new to security

hello,
I have been working in telecom/networking for the past 3 years and looking to join the security team of the company.
I have some security knowledge such as access-lists, how nat works, firewall rules .. but nothing too deep.
I just want to get familiar with the check point interfaces BUT also learn security principles.
What would be the best way to gain that security knowledge + check point all together ... is there a book that covers it up ?

the Syngress Configuring Check Point Ngx Vpn-1/firewall-1 looks alright.


I am just scared to buy a book that is too much into the "get certified by cramming" mentality that doesn't really cover the security knowledge to learn.

thanks for your help guys ....
and yes I did look at other posts but never really found my specific answer.
