  - Site security considerations
    To enhance the security of your HCL Commerce site, you can enable various features in Administration Console or in the HCL Commerce configuration file.
    - Enabling password invalidation
      Password invalidation, when enabled, requires HCL Commerce users to change their password if the user's password is expired. In this case, the user is redirected to a page where they are required to change their password. Users are not able to access any secure pages on the site until they change their password.
    - Encrypting data
      This section contains information about the important steps involved when ensuring the security of your site. There are different encryption options available including information on Key Locator Framework, where you encrypt your data, how to change your session encryption keys and how to develop custom code using EncryptionFactory.
    - Configuring Transport Layer Security protocols
      Configure the latest Transport Layer Security (TLS) protocols for the transaction server to protect your site and comply with security standards. TLS 1.3 is the most secure protocol available, while TLS 1.2 is also considered a secure protocol.
    - Enabling the X-Frame-Options header
      You can configure the X-Frame-Options header settings to help you protect your site against clickjacking. Clickjacking is a technique that tricks a web user into clicking a malicious site, thinking that it is your site. This malicious site can then reveal confidential information or take control of the user's computer.
    - Enabling cross-site scripting protection
      When enabled, cross-site scripting protection rejects any user requests that contain attributes (parameters) or strings that are designated as not allowable. You can also exclude commands from cross-site scripting protection by allowing the values of specified attributes for that particular command to contain prohibited strings. Cross-site scripting protection is enabled by default.
    - Enabling cross-site request forgery in Spring
      Cross-site request forgery (CSRF) is a type of malicious attack that tricks a user into sending unintended requests. For example, an attacker can trick an authenticated user into clicking a link to update their personal information. HCL Commerce accepts this request as valid, as proper session cookies exist as part of the request.
    - Disabling cross-site scripting protection for the Management Center
      When enabled, cross-site scripting protection rejects any user requests that contain attributes (parameters) or strings that are designated as not allowable. You can also exclude commands from cross-site scripting protection by allowing the values of specified attributes for that particular command to contain prohibited strings. Cross-site scripting protection is enabled by default, but you can disable it to match your security needs.
    - Enabling WhiteList data validation
      When enabled, WhiteList data validation ensures that when a URL command or view is run, the parameter values conform to a specified regular expression. For example, you can configure it so that the storeId must be an integer. When a WhiteList violation is detected, the request is changed to the ProhibCharEncodingErrorView view. WhiteList data validation is disabled by default.
    - Enabling cross-site request forgery protection in Struts
      Cross-site request forgery (CSRF) is a type of malicious attack that tricks a user into sending unintended requests. For example, an attacker can trick an authenticated user into clicking a link to update their personal information. HCL Commerce accepts this request as valid, as proper session cookies exist as part of the request.
    - Enabling cross-site request forgery protection in REST
      Enabling cross-site request forgery (CSRF) protection is recommended when using REST APIs with cookies for authentication. If your REST API uses the WCToken or WCTrustedToken tokens for authentication, then additional CSRF protection is not required.
    - Enabling URL redirect filtering
      When you enable URL redirect filtering, HCL Commerce rejects any requests that try to redirect to an unauthorized site. This feature is used to prevent phishing attacks where a link in an HCL Commerce site sends the shopper to another site.
    - Enabling access logging
      When enabled, the access logging feature logs either all incoming requests to the Transaction server or only the requests resulting in access violations. Examples of access violations are authentication failure or insufficient authority to execute a command. When enabled, access logging allows an HCL Commerce administrator to quickly identify security threats to the HCL Commerce system.
    - Enabling SSL for outbound web services
      You can enable SSL for web services by using the WebSphere Application Server administrative console for development and testing, and by using Run Engine commands for permanent configuration changes.
    - Encrypting data in custom code using EncryptionFactory
      EncryptionFactory is a factory class that initializes all of the encryption provider classes that are used at runtime for encrypting and decrypting data. All encryption providers must implement the com.ibm.commerce.foundation.common.util.encryption.EncryptionProvider interface.
    - Web server security considerations
      Be aware of the following security considerations for your web server and take the recommended actions to minimize any security exposure.
    - Setting up account related policies
      For enhanced security of your site, ensure that you are aware and up to date on all account related policies.
    - Enabling password-protected commands
      When the password-protected commands feature is enabled, HCL Commerce requires registered users who are logged onto HCL Commerce to enter their password before continuing a request that runs designated HCL Commerce commands. When you configure password-protected commands, be aware of the consequences of specifying a command that can be run by generic and guest users. Configuring such commands as password-protected will prevent generic and guest customers from running them.
    - Configuring Reset Password to use long validation codes
      When a registered user requests a reset of a forgotten password, you can configure the Reset Password URL to send a randomly generated validation code instead of a temporary password. By default, this code can be up to 100 characters long.
    - Prevent privileged users from logging in externally
      The wc-server.xml file includes a customizable web server header. You can edit this header to control whether privileged users can log in to the store from external networks. This framework reduces the possibility of an external attack if an account with administrative level access, such as a customer service representative or site administrator, is compromised.
  - Session management
    Browsers and e-commerce sites use HTTP to communicate. HTTP is a stateless protocol, which means that each command is run independently without any knowledge of the commands that came before it. Because it is a stateless protocol, sessions must be managed between the browser side and the server side.
  - Quick reference to user IDs, passwords, and Web addresses
    Administration in the HCL Commerce environment requires a variety of user IDs. These user IDs along with their requisite authorities are described in the following list. For the HCL Commerce user IDs, the default passwords are identified.
  - Enabling WebSphere Application Server security
    You can enable WebSphere Application Server security, which includes two orthogonal components: WebSphere global security and Java 2 security.
- Performance
  Topics in the Performance section describe the means by which to plan, implement, test, and re-visit the optimization of HCL Commerce site performance.
- Troubleshooting
  Topics in the Troubleshooting section highlight common issues that are encountered with HCL Commerce, and how they can be addressed or mitigated.
- Reference
  Topics in the Reference section contain all of the HCL Commerce reference documentation.

Configuring Transport Layer Security protocols

Configure the latest Transport Layer Security (TLS) protocols for the transaction server to protect your site and comply with security standards. TLS 1.3 is the most secure protocol available, while TLS 1.2 is also considered a secure protocol.

Procedure

For HCL Commerce 9.1.6 or later, follow these steps to enable TLS 1.3 support:

Verify TLS 1.3 requirements.
Ensure you are running HCL Commerce 9.1.6.0 or later to enable TLS 1.3, as this support was introduced with WebSphere Application Server 9.0.5.6.
If your environment is running HCL Commerce 9.1.6 to 9.1.18, follow these additional steps:
1. Navigate to /SETUP/scripts/ and open setSSLProtocol.py.
2. Locate the protocolList variable.
3. Modify the array to ensure both 'TLSv1.3' and 'TLSv1.3,TLSv1.2' are included:
```
protocolList = ['SSL_TLSv2', 'TLS', 'TLSv1', 'TLSv1.1', 'TLSv1.2', 'TLSv1.3', 'TLSv1.3,TLSv1.2', 'SSL_TLS', 'SSL', 'SSLv2', 'SSLv3']
```
