Since the emergence of computer networks (for example, the internet) about 50 years ago, it is estimated that 50 billion devices will be connected to the internet by 2020.
Businesses now, more often than not, are run as online services; host sensitive databases; have several different office locations; and share large quantities of sensitive data. Cyber attacks, in several forms, are increasing in frequency, complexity, and impact. Cyber incidents (for example, cybercrime, IT failure, and data breaches) are considered the second biggest global risk to business. The world is currently short of 3 million cybersecurity experts.
The CCNA Cybersecurity Operations certification demonstrates candidates' knowledge and abilities. This book equips readers with the skills required to succeed at the SECOPS 210-255 exam, and, for those resitting, to understand their score report and quickly identify the appropriate sections to concentrate on.
