Securing
Security tasks include setting up property extension databases and custom user repositories, configuring and activating SSL, and configuring authentication. In addition, tasks such as activating Federal Information Processing Standards (FIPS) and NIST SP800-131a security modules and configuring external security managers such as Security Access Manager might be required to secure your portal environment.
Security and authentication considerations
Security and authentication are key elements of a production environment. Learn about single sign-on, credential vaults and external security managers.
Caching considerations
Information that is protected by access control and is therefore restricted to a limited set of people needs special consideration when served from an access control agnostic cache. These considerations especially apply to server side caches but you also need to consider local browser caches.

  New and existing users need to register at the HCL Software License Portal and download their entitled HCL Digital Experience package(s).
- Creating your website
  Review the following topics to understand how to create your website using the latest HCL Digital Experience.
- Installing HCL Digital Experience
  Review the planning information on HCL Digital Experience, then select your operating system and installation pattern that most reflects your business needs.
- Configuring
  Run the following tasks after you install and deploy HCL Digital Experience. They address tasks that are typically run one time and have a global effect. Some configuration changes are made more frequently or do not have a global effect. These tasks are addressed in the Administering section.
- Backup and restore
  Backup and recovery of data files and databases is an essential operation for any business system, particularly for data and applications that run in production environments. Create and follow a plan for backing up and recovering data on all tiers of your HCL Digital Experience deployment. IBM Installation Manager must also be included in backup and recovery planning. If you back up the HCL Portal file structure and then install a fix pack, your HCL Digital Experience and IBM Installation Manager become out of sync after you restore the HCL Portal file system. This condition is not recoverable.
- Migrating
  Successful migration requires significant planning and preparation, understanding the tools that are involved, and careful execution of the appropriate steps in the order provided.
- Integrating
  Integrate HCL Digital Experience with software such as HCL Sametime to enable your users to collaborate more easily. You can also use the unified task list portlet to integrate HCL with your backend business process software, such as IBM Process Server.
- Administering
  Use the administration tools that are provided with the HCL Digital Experience to do various day-to-day administration tasks.
- Securing
  Security tasks include setting up property extension databases and custom user repositories, configuring and activating SSL, and configuring authentication. In addition, tasks such as activating Federal Information Processing Standards (FIPS) and NIST SP800-131a security modules and configuring external security managers such as Security Access Manager might be required to secure your portal environment.
  - Security and authentication considerations
    Security and authentication are key elements of a production environment. Learn about single sign-on, credential vaults and external security managers.
    - Authentication
      Authentication requires users to identify themselves to gain access to a system or resources. The combination of a user ID and a password is the most common method of authentication. Users can identify themselves immediately upon entry to the system or the system can prompt users to identify themselves before accessing protected resources. After users successfully authenticate, the system identifies which resources-specific users have sufficient authorization to access.
    - Federal Information Processing Standards and (NIST) SP800-131a
      Federal Information Processing Standards (FIPS) and NIST SP800-131a are standards and guidelines issued by the United States National Institute of Standards and Technology (NIST) for federal government computer systems. FIPS and SP800-131a are developed when there are compelling federal government requirements for standards, such as for security and interoperability, but acceptable industry standards or solutions do not exist.
    - Planning for single sign-on
      Single sign-on provides a secure method of authenticating a user one time within an environment and using that authentication (for the duration of the session) to access other applications, systems, and networks. In the context of HCL Digital Experience there are two single sign-on realms; one realm from the client to the portal and other web applications and the other realm from the portal to the backend applications.
    - Secure communications using SSL
      Configuring HCL Digital Experience for SSL adds security to the client-portal exchange. It encrypts all traffic between the client browser and the server, so that no one can "eavesdrop" on the information that is exchanged over the network between the client browser and HCL Digital Experience. In addition, assuming that the IBM WebSphere Application Server is also configured to accept or require SSL connections, the LTPA Token and other security and session information can be protected against hijack and replay attacks.
    - Credential Vault
      The Credential Vault is a service that stores credentials that allow portlets to log in to applications outside the realm on behalf of the user.
    - Caching considerations
      Information that is protected by access control and is therefore restricted to a limited set of people needs special consideration when served from an access control agnostic cache. These considerations especially apply to server side caches but you also need to consider local browser caches.
  - Controlling access
    After creating users and groups, you can assign them different levels of access to specific resources, roles, and policies. This access controls what actions they can perform on various pages, portlets, and applications.
  - Enabling Attribute Based Security
    Attribute based security for HCL Web Content Manager content is an access filter in the product filter chain. You can extend the access control permission checks for HCL Web Content Manager content beyond the user or group-based decisions. You can define your own criteria. The criteria might involve categories, keywords, textComponents, htmlComponents, or shortTextComponents for an item.
  - Java 2 security
    Java 2 (J2SE) security provides a policy-based, fine-grain access control mechanism that increases overall system integrity by checking for permissions before allowing access to certain protected system resources. J2SE security allows you to set up individual policy files that control the privileges assigned to individual code sources. If the code does not have the required permissions and still tries to execute a protected operation, the Java™ Access Controller will throw a corresponding security exception.
  - Integrating with OpenID authentication
    Web applications provide information and services to public users and personalized information and services to authenticated users. Users often work with multiple web applications, which require multiple IDs and passwords. This requirement can be difficult to maintain. Integrating identity providers (Google, Yahoo, or Facebook) into your site can simplify logging in for your users.
  - Integrating with IBM WebSphere Application Server TAI authentication
    This roadmap outlines integration with IBM WebSphere Application Server Trust Association Interceptors (TAI) authentication for your environment.
  - Enabling step-up authentication and/or the Remember me cookie
    Using step-up authentication and/or the Remember me cookie lets you fine-tune user authentication to pages and portlets.
  - Securing LTPA keys on a production environment
    The Lightweight Third Party Authentication (LTPA) key holds cryptographic keys that secure the user authentication session and cookies. To secure the production server environment, regenerate the LTPA key using the WebSphere Integrated Solutions Console. If you plan to enable single sign-on at a later time, you must first disable the automatic key generation.
  - Configuring SSL
    Secure socket layers (SSL) encrypt traffic between the client browser and the server to secure information exchanged over the network between the browser and HCL Digital Experience. You will need to configure your environment for SSL to activate this additional security feature.
  - Enabling FIPS and (NIST) SP800-131a
    HCL Digital Experience tolerates IBM WebSphere Application Server support of Federal Information Processing Standards (FIPS) and National Institute of Standards and Technology (NIST) SP800-131a. You can configure WebSphere Application Server to activate FIPS 140-2 compliant security modules. When you enable FIPS, you can use only FIPS to securely encrypt data. For this reason, you must also configure FIPS for systems that require secure transactions, which can include HTTP servers and LDAP servers.
  - Configuring Session Security Integration
    IBM WebSphere Application Server protects your session from access by other users.
  - Enabling HTTP Basic Authentication for simple clients
    HCL Portal provides an HTTP Basic Authentication Trust Association Interceptor that can be enabled to allow specific clients to log into the portal by using HTTP Basic Authentication instead of HTTP Form Based Authentication.
  - Setting up custom user repositories
    A custom user repository is any repository that HCL Portal does not support out-of-box. However, you can configure HCL Portal to support any type of repository in a federated or stand-alone user registry, whether an LDAP directory, database, file system, and so on. Setting up custom user repositories involves tasks such as defining additional repositories to the default federated user registry, creating a custom stand-alone user repository, and updating your user repository to reflect changes in your environment. Learn what steps are required to create and update custom user repositories and what specific interfaces you must implement to enable communication between HCL Portal and a repository.
  - External security managers
    Use external security managers such as IBM Security Access Manager to perform authentication and authorization for HCL Digital Experience. You can use an external security manager for authentication only or for both authentication and authorization. Using an external security manager to perform only authorization is not supported at this time.
  - Deleting passwords from properties files
    The configuration tasks might require you to write security-sensitive information, such as passwords, into multiple properties files. When you no longer need this security-sensitive information for your configuration, you should remove them and move the files to a safe place or set the file permissions so that only authorized users can read them.
  - Updating user ID and passwords
    HCL Digital Experience and IBM® WebSphere® Application Server use some accounts from the registry (for example, the LDAP server) including administrative and bind IDs for authenticated access to databases and LDAP severs respectively, as well as the HCL Portal and WebSphere Application Server administrative IDs. Often this means that the account passwords are stored in the HCL Portal and WebSphere Application Server bootstraps configuration files, which allows the authentication process to work.
  - Content Security Policy
    The Content-Security-Policy header is used by modern browsers to enhance security of HCL Digital Experience site documents or webpages by allowing HCL Digital Experience administrators or developers declare which dynamic resources are allowed to load.
- Monitoring
  HCL Portal includes tools and features to help you monitor the portal site.
- Setting up a website
  Setting up a website includes, creating pages, adding navigation, setting up search, and adding content to the site. Themes are used to customize the portal's look-and-feel. Out-of-the-box templates and the site wizard can help you set up your portal site faster. You can add wikis and blogs to your site and let users tag and rate content on your site.
- Staging to production
  During portal solution development, the solution is initially developed, tested, and refined on one server or a limited number of servers. The solution is deployed later on live systems, referred to as the production environment. The process of moving the solution from the development environment to the production environment is called staging.

Caching considerations | HCL Digital Experience

Information that is protected by access control and is therefore restricted to a limited set of people needs special consideration when served from an access control agnostic cache. These considerations especially apply to server side caches but you also need to consider local browser caches.

Browser caches usually have no issues unless the computers are shared between multiple users with different levels of access. If you access HCL Digital Experience from a shared computer, know that all users who have access to the computer can access content that is cached in the local browser cache. To prevent this from happening, do not enable public or private caching of the content. Caching is disabled by default.

Depending on the type of browser you are using, you can still experience information leakage from shared computers, even if caching is disabled. Some browsers serve content that is accessed from the browser's Back button from a separate history cache that is not affected by HTTP caching directives. As a result, if you click the Back button, you may see content that is generated from the previous user even if the previous user performed a logout. To prevent this, the markup that is rendered on logout should explicitly clear the browser's history cache, which typically requires browser-specific script coding, or display a message to close all browser windows after logout. History cache can typically be disabled in the browser but it may be activated by default.

The HCL Digital Experience Performance Tuning Guide provides information about caches for HCL Portal and HCL Web Content Manager. After you have setup your environment, review the tuning guide to learn more about stand-alone and cluster tuning, and then read about both HCL Portal and HCL Web Content Manager caches.
