The article highlights the critical importance of data encryption in the context of the rapid increase in data production, transmission, and consumption. It underlines the necessity of data protection for organizations managing large volumes of sensitive information, such as personal, financial, and health data, which are susceptible to breaches if not adequately secured. Data encryption, which involves converting plaintext into unreadable cipher-text, plays a vital role in safeguarding data privacy, security, and integrity, particularly against cyberattacks. The article discusses two main encryption methods—symmetric and asymmetric—and emphasizes their use in protecting data both at rest and in transit. Several high-profile data breaches from 2020 illustrate the potential consequences of inadequate data protection, including financial losses and damage to reputation. It also reviews key data privacy laws like HIPAA, PCI DSS, GDPR, and CCPA, which mandate or strongly encourage encryption to mitigate breach risks. The article advocates for best practices in encryption, such as securing encryption keys and protecting data throughout its lifecycle, as a means to prevent breaches and comply with regulations, ultimately aiming to enhance information security.
