Information security refers to the practice of protecting information from unauthorized access, use, disclosure, disruption, modification, or destruction. It involves implementing various measures and protocols to ensure that sensitive data, such as personal details, financial records, and intellectual property, remains confidential and secure. This is crucial for individuals and organizations to maintain trust and comply with legal regulations. Key components of information security include encryption, which scrambles data to prevent unauthorized access, and firewalls, which act as barriers between trusted networks and potential threats. Additionally, regular security audits and employee training help identify vulnerabilities and promote a culture of security awareness.
