Tokenization replaces actual cardholder data with a unique identifier (token) that is stored securely. Encryption ensures that data transmitted between your website and the payment gateway is unreadable to unauthorized parties.
Implement SSL/TLS Encryption
Secure Socket Layer (SSL) or Transport Layer Security (TLS) encryption is crucial for protecting data in transit between your website and users’ browsers. Implementing SSL/TLS encryption ensures that sensitive information, such as login credentials and payment details, is transmitted securely.
Obtaining an SSL/TLS Certificate
Obtain an SSL/TLS certificate from a trusted certificate authority (CA) to enable HTTPS encryption on your website. There are various types of SSL/TLS certificates available, including domain-validated (DV), organization-validated (OV), and extended validation (EV) certificates. Choose the certificate type that suits your business needs and provides the necessary level of security.
Enabling HTTPS and Redirects
Once you have obtained the SSL/TLS certificate, configure your web server to enable HTTPS. Ensure that all pages, including checkout and payment pages, are accessed via HTTPS. Implement redirects to automatically redirect users from HTTP to HTTPS to ensure a secure browsing experience.
Regularly Backup Your Website
Performing regular backups of your ecommerce website is crucial to ensure that you have a recent copy of your data in case of any security incidents or data loss. Regular backups provide a means to restore your website to a previous state and recover any lost data.
