Information Security refers to protecting information and its associated systems from unauthorized access, use, disclosure, or destruction. It involves implementing various technologies, processes, and practices to maintain the confidentiality, integrity, and availability of data. This can include measures such as firewalls, encryption, intrusion detection systems, security policies, user authentication, and access control mechanisms. The goal is to ensure that sensitive information remains secure and protected from threats such as hacking, phishing, malware, and other cyber attacks.
