Data security by design and best security practice
GDPR to the developers and architects means implementing good security measures and good security principles.
Implementing secure web servers and infrastructure Servers should be properly restricted using Bastion host and firewall. Access to the servers should be auditable. If you are looking for security review or like to enhance the security of your website or servers, please check Managed Cloud service.
Always upgrade software packages It is a best practice for security to keep the software packages version up-to-date.
Integrity and confidentiality Implementing HTTPS and SSL data encryption for personal data transit. Implementing password and encryption for client files. Pseudonymisation for the testing environment or staging environment.
Data encryption by default Don’t store sensitive personal data in the database with plaintext, Encrypt the data entities with keys or password. Obfuscate the personal data such as user address, bank account etc.
If you are a Transfon PHP Encoder customer, you would be able to use the build-in encrypt and decrypt functions for the transparent sensitive data encryption and decryption.
Keep data storage safe Enable the data encryption on the server disk. Enable FileVault if you use MacOS. Enable data encryption at your backup storage such as AWS S3 or offline storage.
Keep application layer secure Protect your application and business logics with PHP Encoder (if your application is built with PHP) from the modification even the server is accessed unauthorized.
Logging and auditable personal data access Log the access to personal data at all layers from a server to application, database.
Data minimization principle
Only collect and process the data necessary for the application or business logic. Keeping data for no longer than necessary.
Data retention and deletion
Data retention and deletion schedules for all the personal data you hold.
Should be able to find, delete, export all the data related to one user by user ID.
But it is fine to keep all purchasing records for ten years for tax and auditing purposes if you are an e-commerce company, just keep the process on the record.
