Data protection is now one of the most critical and perhaps number one priorities for organizations. With data breaches at an all-time high and new regulations such as GDPR and likes of it coming into force, organizations are now focusing on the Data-Centric Security approach. As such Encryption is one of the oldest yet one of the most effective technology solutions that can enable organizations to achieve Data-Centric Security.
The journey of encrypting data follows a thorough process that consists of:
While Encryption has been in use for centuries, its application depends on the context of information being processed and the relevant business requirement. As such while it may sound easy Encryption has its own set of challenges that should be taken care of while designing an Encryption solution. At Encryption Consulting we understand these challenges
1. Data Discovery:
The first and foremost action for an organization is to locate their sensitive and critical data that requires Encryption which is achieved through means of data discovery and assessment.
Discussing with business stakeholders and Data custodians
Selecting and deploying Data discovery tools for structured, unstructured, and semi-structured data stores
2. Key Management: Cloud or On-Premise
Key management is one of the most critical components of Encryption. It is very important to carefully identify and design best approach suited for your needs
Ensuring Secure keys with constant protection
Not allowing access of keys to cloud administrators
Controlling keys as the Customer
If a customer deletes its key, then data will be removed as well
Maintaining on-premise control of key
Confinement of Key
Utmost dedication to the key management platform
Never allowing key swaps
Avoid over-use of the key which permits vulnerability
Re-keying data with a new key to creating a new key
3. Querying Encrypted Data:
Quite often is required to search and index encrypted data stored on-premise or in the cloud. This is a big concern for organizations since this might involve decrypting data many often and thus increasing the opportunity for a hacker to get access to decrypted data. Additionally, frequent decryption can increase the demand for system resource requirements and time.
4. Performance Overhead
Whenever data is encrypted, a performance overhead is associated with encryption. The amount of data encrypted may cause a slowdown for systems.
5. Encryption Algorithm and Key Length
Another important aspect of Encryption is the selection of the Encryption algorithm & Key Length. While selecting a higher key length can enhance Security and reduce risks of Key compromise it can cause performance impact as a higher key length will consume more resources and time. Thus a careful understanding of throughput and business needs should be evaluated for the selection of the Encryption algorithm and Key length
6. Challenges of Encryption Program Management:
When deciding on which type of encryption is best for your organization, the challenges organizations face with encryption program management are:
Meeting set requirements and compliances
Assess products/vendors available
Confirmation of product/vendor
Creating and tuning a secure environment
Plan for system integration
Set Formal Policies
Formatting of Data
Conduct Performance Test
We at Encryption Consulting can help our customers plan and design the most suitable Encryption option for securing your data irrespective of where they are stored and without compromise on business performance or user experience.
