What Is Information Security?

Information security (InfoSec) is all about protecting important information from being accessed, stolen, or damaged by unauthorized people. It ensures that data remains private, accurate, and available when needed. As someone familiar with InfoSec, you know how crucial it is for everyone—whether it's safeguarding personal details, a company’s confidential information, or government data. InfoSec covers key areas like cybersecurity (protecting against hackers), data protection, and risk management to prevent potential threats. In short, infosec plays a vital role in ensuring that our digital world remains safe, secure, and reliable.
