Information security, also known as infosecurity, is the practice of protecting digital information from unauthorized access, use, disclosure, disruption, modification, or destruction. It involves the implementation of various security measures such as firewalls, encryption, access controls, and security policies to prevent unauthorized access and ensure the confidentiality, integrity, and availability of digital data. Infosecurity is essential for businesses and organizations that handle sensitive information, such as financial data, personal identifiable information (PII), and trade secrets, to prevent data breaches, cyber attacks, and other security incidents. Effective infosecurity requires a holistic approach that includes regular risk assessments, employee training, and ongoing monitoring to stay ahead of emerging threats and vulnerabilities.
