Summary

Modern organizations rely on Security Operations Center (SOC) teams to vigilantly watch security systems, rapidly detect breaches, and respond quickly and effectively. To succeed in these crucial tasks, SOCs desperately need more qualified cybersecurity professionals. Cisco's new CCNA Cyber Ops certification prepares candidates to begin a career working with associate-level cybersecurity analysts within SOCs. To earn this valuable certification, candidates must pass two exams. CCNA Cyber Ops SECFND #210-250 Official Cert Guide is Cisco's official, comprehensive self-study resource for the first of these two exams.

 

Designed for all CCNA Cyber Ops candidates, it covers every SECFND #210-250 objective concisely and logically, with extensive teaching features designed to promote retention and understanding. You'll find:

• Pre-chapter quizzes to assess knowledge upfront and focus your study more efficiently
