SSL encryption refers to the use of Secure Sockets Layer technology to protect data transmitted between a user’s browser and a website. Today, modern websites generally use TLS (Transport Layer Security), which replaced SSL, although the term “SSL” is still commonly used.

In eCommerce, encryption helps protect information such as:

• Customer login credentials
• Personal information
• Payment-related data
• Addresses and order information
• Information submitted through website forms

For example, when a customer enters information on an eCommerce checkout page, HTTPS/TLS encrypts the connection between the customer’s browser and the website, making it more difficult for unauthorized parties to intercept the transmitted data.

SSL/TLS certificates also help authenticate a website’s identity and enable browsers to establish a secure HTTPS connection. A website using HTTPS typically displays a padlock icon in the browser.

SSL/TLS encryption is an important part of eCommerce security, but it is not a complete security solution. Businesses also need appropriate authentication, access controls, secure applications, payment security, monitoring, and data-protection practices.

User access control is the process of controlling who can access an eCommerce system, what information they can view, and which actions they are allowed to perform. It helps protect business data and ensures that users receive only the permissions necessary for their responsibilities.

In B2B eCommerce, access control can include:

• User authentication – Verifying users through passwords, multi-factor authentication, or other methods.
• Role-based permissions – Giving different access levels to administrators, sales staff, buyers, finance teams, and other users.
• Account-level access – Restricting customers to their own company account, catalogs, pricing, orders, or locations.
• Administrative permissions – Controlling who can modify products, prices, orders, customer records, or store settings.
• Approval controls – Requiring authorized users to approve certain orders, discounts, or purchasing actions.
• Access monitoring – Recording and reviewing login and permission-related activities.

For example, a B2B company might allow a purchasing employee to create orders and view company pricing, while only a finance manager can access billing information or approve high-value purchases.

Effective access control follows the principle of least privilege, meaning users receive only the access required to perform their role. Permissions should also be reviewed regularly and removed or updated when responsibilities change.

Audit logs are important because they record activities and changes made within an eCommerce system, helping businesses understand who performed an action, what was changed, and when it happened. They provide a historical record that can support security, troubleshooting, compliance, and accountability.

In B2B eCommerce, audit logs can help businesses:

• Monitor user activity – Track logins, account changes, and administrative actions.
• Detect security issues – Identify unusual or unauthorized activity.
• Investigate incidents – Determine what happened after an error, data change, or security event.
• Support compliance – Provide evidence that certain activities and controls are being monitored.
• Improve accountability – Show which user or system performed a specific action.
• Troubleshoot problems – Help identify when and how a configuration or data change occurred.
• Track sensitive changes – Monitor changes to pricing, permissions, customer accounts, orders, and other important settings.

For example, if a B2B customer’s pricing unexpectedly changes, an audit log may show which authorized user changed the pricing configuration and when the change occurred.

Audit logs are most useful when they are protected from unauthorized modification, retained for an appropriate period, and regularly monitored for significant or suspicious activity.

Data backup in eCommerce is the process of creating and securely storing copies of important online store data so it can be restored if the original data is accidentally deleted, corrupted, lost, or affected by a technical or security incident.

eCommerce backups may include:

• Product data – names, descriptions, prices, SKUs, variants, and inventory information.
• Customer data – customer profiles and relevant account information.
• Order data – order history, transactions, and fulfillment information.
• Website content – pages, blog posts, images, and other media.
• Store configuration – settings, themes, customizations, and certain integrations.
• Business records – invoices, reports, and other important operational data.

Backups can be performed automatically or manually and stored in separate systems or cloud storage. Businesses may also maintain multiple backup versions so they can restore data from an earlier point in time.

For example, a B2B eCommerce business could back up its product catalog, customer records, and order data before performing a major platform migration or store customization.

Regular backups can help reduce downtime, data loss, and recovery costs. Businesses should also protect backup files with appropriate access controls and security measures and periodically test whether the data can actually be restored.
