Security overview
The security of your data and digital experiences is our priority. To better protect Adobe Commerce and Magento Open Source installations from the physical layer up, we have implemented hundreds of processes and controls to help us comply with industry-accepted standards, regulations, and certifications. To help protect installations from the software layer down, we build in security measures that are based on the Adobe Secure Product Lifecyle.
Although there is no single way to eliminate all security risks, there are many steps you can take to harden your installations and make them a less attractive target for bad actors. The Security Best Practices Guide offers insight and practical guidelines to help protect all installations from security incidents.
Examples of built-in security measures
Enhanced password management
Magento has strengthened the hashing algorithms (SHA-256) used in password management. Magento now supports Argon2ID13 through the PHP sodium extension, which requires the libsodium library version 1.0.13 or higher.
Improved prevention of cross-site scripting (XSS) attacks by making escaped data the default
The Magento Framework has adopted conventions that regulate the escaping of data in output. These conventions include the ability to escape output for HTML pages (HTML, JSON, and JavaScript) and email. Where possible, escaping is transparent to client code. See Security measures against XSS attacks in the Frontend Developer Guide.
More flexible file system ownership and permissions
Starting in version 2.0.6, Magento no longer explicitly sets file system permissions. Instead, we recommend that certain files and directories be writable in a development environment and read-only in a production environment.
To provide you with a simple way to restrict access to the file system in production, we provide the flexibility for you to further restrict those permissions using a umask.
For an overview, see Overview of ownership and permissions.
For details about ownership and permissions in development and production, see Magento ownership and permissions in development and production.
Improved prevention of clickjacking exploits
Magento safeguards your store from clickjacking attacks by using an X-Frame-Options HTTP request header. For more information, see X-Frame-Options header.
Use of non-default Admin URL
A simple Admin URL (like admin or backend) makes it easy to target attacks on specific locations using automated password guessing. To prevent against this type of attack, Magento by default creates a random Admin URI when you install the product. The CLI command php bin/magento info:adminuri is provided so that you can see the URI if you forget it. You can also use the CLI to change this URI. Although the use of a non-default admin URL will not secure the site, its use will help prevent large-scale automated attacks. See Display or change the Admin URI in Configuration Guide for more information.
