CompTIA Security+ SY0-401 by Keith Barker
The CompTIA Security+ certification is an internationally recognized validation of foundation-level security skills and knowledge. The exam will certify that the successful candidate can identify risk, participate in risk mitigation activities, and provide infrastructure, application information and operational security. This course will prepare you for this certification including the knowledge of security controls to maintain confidentiality, integrity and availability.
If you're looking for a solid foundation in network security, this Security+ video training is for you!
It's also for you if you're an IT manager or CIO and want to extend your security knowledge, if you're preparing for a high-level certification such as CISSP, you're making a career change, or you're working in industries governed by HIPAA, SOX, or the office of Homeland Security.
Corporations often have trouble finding qualified applicants to fill their security positions. This training, which maps to CompTIA's Security+ exam, separates you from the crowd and increases your value to any employer.
Convincing your IT manager that the network is secure (and then following up with the skills to ensure that security) translates into job security.
This course prepares the candidate for the requirements of the current SYO-401 certification exam.
