Encryption is a foundational control in contemporary organizational security programs, essential for protecting information assets as data flows across networks, is stored across diverse systems, and is entrusted to third-party services. In the modern threat landscape, organizations face a broad spectrum of attacks—from credential harvesting and database breaches to supply-chain compromises and ransomware. Encryption, when properly designed and managed, reduces the likelihood that sensitive data can be exploited if a breach occurs. It also helps organizations comply with regulatory requirements that mandate the protection of personal and financial information. In this discussion, I focus on applications of encryption today and explain two concrete uses, including what resources they guard and why those protections matter from a security perspective. Throughout, I reference established standards and regulations to anchor the discussion in credible, industry-accepted practices (NIST SP 800-111; NIST SP 800-57; GDPR; PCI DSS; ISO/IEC 27001).

One prominent use case is database encryption, which can be implemented via Transparent Data Encryption (TDE) or column-level encryption. TDE protects data at rest by encrypting the database files and backups, ensuring that stored data remains unreadable if physical storage media are stolen or improperly accessed. Column-level encryption protects specific fields that contain highly sensitive information, such as social security numbers, credit card details, health data identifiers, or other PII/PHI elements, without requiring decryption of the entire database for every operation. The information resource that encryption is designed to protect in this scenario is sensitive data stored within databases, including PII and financial records. Protecting these resources is critical to prevent identity theft, financial fraud, and violations of privacy regulations. From a security perspective, database encryption reduces breach impact by ensuring that attackers who gain access to database files cannot easily extract usable information without access to the proper cryptographic keys. It also supports data minimization and access controls by restricting decrypted data to applications and personnel with legitimate need. Standards and guidance support this approach: NIST’s guidance on storage encryption (SP 800-111) and key-management practices (SP 800-57) emphasize protecting data at rest and the importance of robust key lifecycle management, rotation, and separation of duties. PCI DSS, which governs payment card data, explicitly requires encryption of cardholder data and strong key management, reinforcing the business rationale for database encryption in organizations handling payment information. Additionally, GDPR’s Article 32 calls for appropriate technical measures to protect personal data, and encryption is commonly recognized as a suitable safeguard to meet that obligation. In practice, organizations must implement robust key management to avoid a single point of failure; losing access to encryption keys can render data irretrievable, even when data is properly encrypted, illustrating the need for secure, multi-person governance and offline backups of keys (NIST SP 800-57; PCI DSS; GDPR).

A second widely adopted use of encryption is protecting data in transit, including data moving over the internet or across internal networks. Transport Layer Security (TLS) is the standard mechanism for securing web traffic, while email security often relies on S/MIME or PGP to protect content in transit and at rest on mail servers. Encrypting data in transit mitigates the risk of eavesdropping, tampering, and impersonation as information traverses potentially insecure networks. This use case correlates to protecting information resource integrity and confidentiality during transmission, such as customer records before they reach a database or financial metadata while crossing cloud services. The security benefits are well documented in standards such as NIST SP 800-52 Rev. 2, which provides guidelines for TLS configuration and deployment to ensure confidentiality, integrity, and authentication of data in transit. GDPR and ISO/IEC 27001/27002 also built-in expectations for protecting communications and ensuring secure channels for data exchange. The practical takeaway is that encryption in transit complements encryption at rest, creating defense in depth that reduces overall breach surface area.

A third relevant use is encryption for backups and cloud storage, including automated encryption of data before it leaves on-premises environments or when stored in third-party infrastructure. Backups are an attractive target for attackers because they enable rapid data reconstruction after a breach or ransomware event. Encrypting backups—whether full backups, incremental sets, or cloud snapshots—helps ensure business continuity even if primary data stores are compromised. Key management remains a central concern: keys must be protected, access policies enforced, and key custodians separated from data operators to minimize insider risk. Protecting backups is essential for maintaining data resiliency and meeting regulatory expectations that data remains protected across all copies and storage locations. International standards and frameworks emphasize encryption across data lifecycles, including backup and disaster-recovery environments, and the need for robust cryptographic key lifecycle management and secure storage for backup keys.

In terms of governance and practical implementation, organizations should adopt a data classification program that aligns encryption controls with data sensitivity. Policy should specify when encryption is required, what algorithms and key-lengths are acceptable, and how keys are managed and rotated. Cost considerations, performance impacts, and user experience must be balanced against risk reduction. Enterprises should require secure key management solutions, ideally with hardware security modules (HSMs) or cloud-based key management services that enforce separation of duties, auditability, and rotation. Regular penetration testing and red-team exercises should validate that encryption controls hold up under real-world attack scenarios, and recovery drills should confirm that keys can be retrieved and data decrypted when legitimate access is required. While encryption does not eliminate all risk, it materially reduces the probability of data exposure and contributes to regulatory compliance posture, incident response readiness, and trust with customers, partners, and regulators. Contemporary perspectives on encryption emphasize not just the technology, but governance, risk, and resilience constructs critical to ongoing protection in dynamic environments (NIST SP 800-111; NIST SP 800-57; PCI DSS; GDPR; ISO/IEC 27001).

Response to a hypothetical classmate's post: If a peer emphasizes encryption primarily as a compliance checkbox, I would add that the value extends beyond meeting requirements. Properly implemented encryption reduces the risk of data leakage during insider incidents and third-party breaches, and it preserves business continuity by enabling secure data processing even after a security incident. I would also highlight the importance of robust key management, encryption of backups, and encryption in transit as complementary layers. A common pitfall is assuming that encryption alone solves data security; without strict access controls, key lifecycle management, and monitoring, encrypted data can still be misused. Emphasizing a defense-in-depth approach—combining encryption with least-privilege access, strong authentication, and continuous monitoring—helps ensure encryption contributes meaningfully to the organization’s security posture and incident-readiness in the face of evolving threats (NIST SP 800-57; NIST SP 800-52; PCI DSS; GDPR).

In conclusion, encryption remains a central pillar of organizational security, offering practical protections for data at rest, data in transit, and data during storage and backup. The uses described—database encryption to shield sensitive records, encryption in transit to protect communications, and encryption of backups to preserve resilience—collectively reduce exposure, support regulatory compliance, and strengthen stakeholder trust. The effectiveness of these controls depends on sound key management, proper configuration, and ongoing governance. As technologies such as cloud services, data analytics, and remote work proliferate, encryption will continue to be a critical enabler of secure and trustworthy information systems.
