CompTIA Security+ is now ISO 17024 Accredited with the release of the new version of Security Plus certification, SY0-301, covering some of the latest tpoics such as application secuirty, patch security, HR security, compliance, etc. The domain which is common in both the version is Cryptography. The new version has also merged some old objectives to form a new domain.

This evolved vesion is getting very popular in IT professionals as security is the need of the hour.

I personaly belive that compTIA is the best vendor to get certified from.
