This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
There are some great concepts in this book..may not be very helpful for the exam..but a definite worth of time..
You can also google for specific topics on security..(such as JSSE,SSL,etc..)..to further solidify your concepts..as far as i remember most questions are easy to answer..if you have your security basics right..
