Everything to know about the upcoming Digital Personal Data Protection Bill in India – part 2
In the first part of our two-part series on the upcoming Digital Personal Data Protection Bill (the Bill) in India, we elaborated on the Bill’s various mandates that organizations should keep in mind while storing and processing the personal data of their Indian customers.
In this second part, let’s look at three key technologies – Data Encryption, Centralized Key Management, and Hardware Security Modules (HSMs), that organizations can leverage to safeguard their customers’ personal data and cohesively adhere to the Bill’s data protection guidelines. Let’s begin…
As we are all aware, data encryption is a crucial defense against cyberattacks and data breaches.
By converting plaintext data into illegible ciphertext that can only be deciphered with the corresponding decryption key, data encryption has the potential to prevent threat actors from causing significant damage through various malware attacks, including ransomware, man-in-the-middle (MITM), and DDoS attacks.
When implementing a data encryption strategy, organizations should consider the following factors:
Choosing the right algorithm
Selecting the appropriate encryption algorithm is a key aspect of any data encryption strategy. The most commonly used algorithms globally are the Advanced Encryption Standard (AES) and Rivest-Shamir-Adleman (RSA).
AES, based on symmetric encryption, uses a single shared key for both encryption and decryption. It offers fast performance and is capable of securing large volumes of data with key sizes ranging from 128 bits to 256 bits.
RSA, based on asymmetric encryption, employs separate public and private keys for encryption and decryption. This approach enhances data security by establishing a secure communication channel between senders and receivers.
When choosing an encryption algorithm, consider factors such as the type of data to be encrypted, the performance requirements of your IT systems, and any regulatory mandates specific to your industry.
Encrypting both data-at-rest and data-in-transit
A robust data protection strategy should encompass encryption for both data-at-rest (stored data) and data-in-transit (transmitted data).
To ensure cohesive protection of data-at-rest, organizations should first identify where their sensitive data resides and then encrypt it with the right encryption algorithm. Finally, organizations should implement strong identity and access controls to ensure that only authorized personnel and systems have access to this data.
To secure data-in-transit, organizations should use secure communication protocols such as SSL/TLS or HTTPS to encrypt the transmitted data. These protocols cohesively secure the end-to-end connection between the data sender and the receiver, and seamlessly protect the data from interception or tampering during transmission.
By considering these factors and implementing a comprehensive data encryption strategy, organizations can strengthen their defenses against cyber threats and protect sensitive information
Encryption key management
A common misconception is that simply encrypting data is enough to protect it. However, the truth is that protecting encryption keys is equally critical. Encryption keys go through multiple stages during their lifecycle, such as creation, distribution, storage, rotation, and backup. Safeguarding them at every stage is paramount.
To ensure secure key management, organizations should implement a robust Centralized Key Management solution. Here are two key benefits of such a solution:
Consistent key security
A centralized key management platform enforces uniform security policies across the organization. This ensures that all encryption keys adhere to the same security standards, making it easier to meet regulatory compliance requirements and mitigate the risk of data breaches. By maintaining consistent key security, organizations can ensure the confidentiality and integrity of their encrypted data.
Simplified key lifecycle management
Centralized key management systems streamline the end-to-end key management process by providing a single, unified interface for managing all encryption keys across diverse locations. This simplifies the key management exercise, reducing complexity and the risk of human errors. It allows organizations to efficiently handle key generation, distribution, rotation, revocation, and backup, ensuring smooth operations while maintaining the highest level of security.
By implementing a centralized key management solution, organizations can effectively protect their encryption keys, which are vital for securing sensitive data. It not only strengthens data protection but also facilitates compliance with industry regulations and standards.
Hardware security modules (HSMs)
To ensure the security of encryption keys and prevent the encryption exercise from being rendered futile, organizations should deploy advanced Hardware Security Modules (HSMs) to protect their keys. HSMs are specialized physical devices designed to securely store and manage encryption keys.
When deploying HSMs, organizations should consider the following:
The intended use cases
HSMs come in various types, such as General Purpose HSMs and Payment HSMs, and the choice depends on the specific use case.
General Purpose HSMs can be used for a wide range of activities, including encrypting data-at-rest and data-in-transit, generating and authenticating digital signatures, and key generation, storage, and management for various cryptographic operations.
Payment HSMs, on the other hand, are specifically designed to secure financial transactions and payment processing systems. They have specialized features tailored to meet the stringent requirements of the BFSI industry. Payment HSMs are primarily used for securing credit/debit card PINs, generating, storing, and managing cardholder data, key management for Point-to-Point Encryption (P2PE), and cryptographic processing during data tokenization.
Integration with existing encryption infrastructure
For cohesive data protection, organizations should integrate HSMs with their existing encryption and key management ecosystem.
When selecting an HSM, it is pivotal to check its compatibility with the organization’s existing encryption setup. This includes meticulously checking for the supported encryption algorithms, protocols, and APIs.
Additionally, organizations should choose an HSM that supports their scalability plans, with the capacity to handle anticipated cryptographic loads. Advanced features like clustering, load balancing, and disaster recovery should also be considered to ensure seamless business continuity.
By carefully considering the use cases and integrating HSMs with existing encryption infrastructure, organizations can enhance the security of their encryption keys and strengthen their overall data protection measures.
