Am root, have four years of experience in cisco R&S and security. i beleave in "Learning is more important than having", am passionate to learn security. please suggest me how to prepare CCIE security.
i have certified CCNA security in 2012.
the problem is currently am not getting any exposer on security in present organization. if there is any books/docx/videos to grow my self in cisco security please let me know.
i bought a new laptop with high config to run gns3 if there is any labs for security ( like ASA,IPS,IDS......) please share with me.
I want to thank you all from the bottom of my heart for your help.
Well you need to focus on CCNP Security as a step along the path to CCIE.
Just like with CCNA Security, the official certification guides are very useful. The CCNP Security program recently announced a makeover though and the current exams are being retired in April 2013. So you will be much better off waiting until new guides are published later this year.
GNS3 is fine for modeling routers but not so much for ASA and not at all for switches. Additionally the new syllabus for CCNP Security will emphasize things like CX and ISE which GNS3 will not handle at all.
If you really want to get proficient in Cisco security I sugggest you search for a position that will expose you to it in your day to day job. I see too many folks with certifications and little to no practical experience and they are usually not as qualified as their certifications would suggest.
