Just finished my review of the curriculum for CCNA Security today. Will probabaly take the exam next week. Lots of duplicate information from several other courses but still a good bit of stuff that I've felt belonged to CCNA level studies but was never included in the original CCNA. I'm glad to see the addition of NTP, AAA, IPSec VPN and so many other tools used in production!
Next one will be CCNA Voice followed by the CCNA Wireless. Hope to have those done by the end of the month.
