What is cybersecurity software?

Computer security software is an individual or suite of programs and applications designed to protect data, devices, and networks from unauthorized access and criminal activity. Cybersecurity tools differ from product to product, ranging from an antivirus software to a comprehensive network security system that includes a firewall, detection and response, and centralized monitoring and reporting.

Security software provides protection by stopping access, addition of or changes in files and programs, and copying or transmission of data that are unauthorized and unwanted. Cybersecurity software also alerts users of vulnerabilities that attackers can exploit to compromise confidentiality, integrity, and availability of information.
