Strong encryption forms the foundation of present-day data security. The digital world has embraced encryption protocols and practices to establish secure data storage, handling and transmission across local networks and the wider Internet. Business organizations adopting data encryption are expected to keep up with technology advancements in security and raise their game as they move toward a cloud-driven future. The following best practices in data encryption will empower organizations with superior data security capabilities:
Understand your security objectives in context of business requirements and resource availability. Understand the regulations and governance policies around data security that may apply to your business. Understand how different technology architectures and applications – cloud, big data, etc. – should impact your security strategy.
Define a security framework
To establish a structured approach to data security, your organization needs to define the following aspects of the overall data security strategy:
- Data segregation: Isolate data based on types, security requirements and sensitivity.
- Security key management: Management of cryptographic keys, including the process of key generation, storage, use and replacement.
- Data access controls: Define and enforce mechanisms to control data access based on roles and privileges.
- Auditing and monitoring data access: Keep track of logs and audit trails to identify anomalies and unauthorized data access.
- Data destruct: Establish a system to destroy encryption keys in event of successful security infringement.
Decentralize the process
Implement data encryption and decryption process at a local level and distribute it throughout the network. A decentralized approach ensures high network performance, availability and faster data transmission standards.
Support multiple encryption practices
This strategy is particularly effective for organizations that work with multiple technology partners or expect to integrate their offerings with other providers following a merger or acquisition. By supporting multiple mechanisms for encryption, your organization can adopt encryption standards based on evolving regulatory requirements and advancements in the technology. The encryption framework should also support third-party integration to achieve these goals.
Data encryption forms only one part of an end-to-end security strategy. Business organizations facing rising security threats should establish proactive measures for defense and post-infringement incidents. Deploy multiple layers of security and leverage strong backup and high availability services to ensure your data remains secure and available despite the persistent security risks.
