Domino® server-based certification authority
You can set up a Domino® certifier that uses the CA process server task to manage and process certificate requests. The CA process runs as a process on Domino servers that are used to issue certificates. When you set up a Notes® or Internet certifier, you link it to the CA process on the server in order to take advantage of CA process activities. Only one instance of the CA process can run on a server; however, the process can be linked to multiple certifiers.
Adding a certifier to the CA process
To manage the CA process, use Tellcommands at the server console.

Securing
This section describes security features, including execution control lists, IDs, and TLS.
- Overview of Domino security
  Setting up security for your organization is a critical task. Your security infrastructure is critical for protecting your organization's IT resources and assets. As an administrator, you need to give careful consideration to your organization's security requirements before you set up any servers or users. Up-front planning pays off later in minimizing the risks of compromised security.
- Server access for Notes® users, Internet users, and Domino® servers
  To control user and server access to other servers, Domino® uses the settings you specify on the Security tab in the Server document as well as the rules of validation and authentication. If a server validates and authenticates the Notes® user, Internet user, or server, and the settings in the Server document allow access, the user or server is allowed access to the server.
- The database access control list
  Every .NSF database has an access control list (ACL) that specifies the level of access that users and servers have to that database. Although the names of access levels are the same for users and servers, those assigned to users determine the tasks that they can perform in a database, while those assigned to servers determine what information within the database the servers can replicate. Only someone with Manager access can create or modify the ACL.
- Domino® server and Notes® user IDs
  Domino® uses ID files to identify users and to control access to servers. Every Domino server, Notes® certifier, and Notes user must have an ID.
- The execution control list
  You use an execution control list (ECL) to configure workstation data security. An ECL protects user workstations against active content from unknown or suspect sources, and can be configured to limit the action of any active content that does run on workstations.
- Domino® server-based certification authority
  You can set up a Domino® certifier that uses the CA process server task to manage and process certificate requests. The CA process runs as a process on Domino servers that are used to issue certificates. When you set up a Notes® or Internet certifier, you link it to the CA process on the server in order to take advantage of CA process activities. Only one instance of the CA process can run on a server; however, the process can be linked to multiple certifiers.
  - Setting up a server-based Domino® certification authority
    You set up a server-based certification authority by setting up a certifier or certifiers, and then enabling them for the CA process.
  - Administering a Domino® CA
    There are a number of tasks associated with managing a HCL Domino® certifier. If you implement a certifier that uses the CA process, you can delegate HCL Notes® and Internet certificate request approval and denial to other administrators, each of whom acts as a registration authority. Many of the manual tasks associated with managing a CA in prior versions of Domino are automated when you use the CA process.
  - Migrating a certifier to the CA process
    To migrate an existing certifier to the CA process, you set up an Issued Certificate List (ICL) database and configure its certificate duration. In addition, for Internet certifiers, you configure CRL and key usage information for the certificate.
  - Adding a certifier to the CA process
    To manage the CA process, use Tellcommands at the server console.
  - Viewing certifiers running under the CA process
    You can view a list of all the certifiers running under the CA process.
  - Creating a certifier for a server-based CA
    You can create additional HCL Notes® and Internet certifiers for your organization and configure them to use the CA process.
  - Creating the Certificate Requests database
    Each Internet certifier you create requires a Certificate Requests database (CERTREQ.NSF) to manage the server keyring file and allow users to request client certificates from the browser or through email. This database stores active certificate and revocation requests that have been submitted to the Administration Process for processing. Using a browser-based interface, servers and clients request certificates and pick up issued certificates.
  - Setting up TLS on a server-based CA server
    Because server administrators and clients use browsers to access the CA server to request and pick up certificates, use TLS to protect the CA server. When you set up the CA server for TLS, you create the server key ring file and request a server certificate. Domino® automatically approves the server certificate and merges the CA certificate as a trusted root.
  - Signing server certificates using the Certificate Requests database
    A Domino® administrator can request a server certificate from a server-based CA in order to enable TLS on a Domino server. The request is entered and processed in the Certificate Request database, where administrators approve or deny the request.
  - Modifying a server-based CA
    After you migrate or create a certifier, you can modify it through the certifier ICL or through the certifier document in the Domino® Directory. How you open a certifier to modify it affects the number and type of changes you can make.
  - Viewing certificate requests
    Domino® CAAs and RAs can view information about server and client certificate requests waiting for approval, as well as approved and rejected requests.
  - Revoking a certificate
    A CA administrator can easily revoke an Internet certificate -- for example, if the subject of the certificate leaves the organization, or if the key has been compromised. After a certificate is revoked, it can never again be trusted.
  - Backing up and recovering a certifier
    Back up each certifier that you create, so that you can recover if there is a problem -- for example, if error messages are generated by the certifier when you issue a lo ca or tell ca refresh command.
  - Disabling a certifier
    To modify a Certifier document, you must have Editor access to the Domino® Directory. Full-access administrators and administrators have this access by default; however, be sure that all certificate authority (CA) administrators also have this access.
- TLS security
  Transport Layer Security (TLS) is a security protocol that provides communications privacy and authentication for Domino® server tasks that operate over TCP/IP.
- TLS and S/MIME for clients
  Clients can use a Domino® certificate authority (CA) application or a third-party CA to obtain certificates for secure TLS and S/MIME communication.
- Encryption
  Encryption protects data from unauthorized access.
- Web-based authentication
  Define and set up authentication methods for web users, for example through basic password authentication, passkeys, time-based one-time password, or single sign-on.
- Using a credential store to store credentials
  A Domino® server can use a credential store application as a secure artifact repository. Examples of secure artifacts include authentication credentials and security keys.
- History of supported key sizes in Notes and Domino
  Understand the RSA key sizes supported by Notes® and Domino® from past releases to the current release.

Adding a certifier to the CA process

To manage the CA process, use Tellcommands at the server console.

About this task

You must reload the CA process each time you restart a server. You can do this through the server console command load ca. As an alternative, you can add the parameter ca to the ServerTasks= line in the server's NOTES.INI file, and the CA process will begin automatically when you start the server.

Procedure

If the CA process is not already running, at the server console enter:
```
load ca
```
If the CA process task is already running, it automatically adds newly-created certifiers when it refreshes, which takes place every 12 hours. However, the time period in which the Administration Requests database processes CA requests will vary. If you want to hasten the process, at the console enter:
```
tell adminp process all
```
```
tell ca refresh
```
And then enter the following to see if the new certifier has been added:
```
tell ca stat
```
