  - 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.
  - SSL security
    Secure Sockets Layer (SSL) is a security protocol that provides communications privacy and authentication for Domino® server tasks that operate over TCP/IP.
  - SSL and S/MIME for clients
    Clients can use a Domino® certificate authority (CA) application or a third-party CA to obtain certificates for secure SSL and S/MIME communication.
    - Setting up Notes® and Internet clients for SSL authentication
      You can set up Notes® or other Internet clients for server authentication to encrypt data and authenticate the server identity when connecting to an Internet server. You do not need an Internet certificate if you set up a client for server-only authentication.
    - Pushing trusted certificates to Notes® clients
      You can create cross-certificates in the Domino® Directory for Internet certifiers and Notes® certifiers and then push the cross-certificates to the Contacts application on Notes clients. The cross-certificates are used to establish client trust of a certifier when accessing servers, reading encrypted S/MIME mail, or installing signed Notes client plug-ins. When you push cross certificates, users are not required to create the cross-certificates or retrieve them from the Domino Directory.
    - Internet certificates for SSL and S/MIME
      Before Internet and Notes® clients can use client authentication or send signed mail, they must have an Internet certificate. To send encrypted mail using S/MIME, they must have the recipient's Internet certificate.
    - Setting up Notes® clients for S/MIME
      You can set up an Notes® client to use S/MIME encryption and electronic signatures when sending mail to other users of mail applications that support S/MIME.
    - Setting up Notes® and Internet clients for SSL client authentication
      You can set up a Notes® or Internet client for client authentication with a server. You cannot use client authentication for SMTP and IIOP connections.
    - Setting up SSL for Notes® or Domino® using SMTP
      A Notes® client or Domino® server can act as an SMTP client when routing mail to an SMTP server. The Notes client or Domino server can use SSL to connect to a Domino server running the SMTP service or to another type of SMTP server. You cannot set up a Notes client or Domino server for SSL client authentication when connecting using SMTP.
    - Using SSL when setting up directory assistance for LDAP directories
      Directory assistance allows you to extend directory services from a server's primary Domino® Directory to other Notes® directories, such as secondary Domino Directories, and to remote LDAP directories. To set up directory assistance, you create a directory assistance database from the DA.NTF template, and then create Directory Assistance documents in the database to configure services for specific directories.
    - OCSP for X.509 certificate revocation checking
      The Online Certificate Status Protocol (OCSP) enables applications to determine the revocation state of an identified certificate. OCSP may be used to satisfy some of the operational requirements of providing more timely revocation information than is possible with certificate revocation lists (CRLs), and may also be used to obtain additional status information. An OCSP client issues a status request to an OCSP responder and suspends acceptance of the certificate in question until the responder provides a response.
  - Encryption
    Encryption protects data from unauthorized access.
  - Name-and-password authentication for Internet/intranet clients
    Name-and-password authentication, also known as basic password authentication, uses a basic challenge/response protocol to ask users for their names and passwords and then verifies the accuracy of the passwords by checking them against a secure hash of the password stored in Person documents in the Domino® Directory.
  - Multi-server session-based authentication (single sign-on)
    Multi-server session-based authentication, also known as single sign-on (SSO), allows Web users to log in once to a Domino® or WebSphere® server, and then access any other Domino or WebSphere servers in the same DNS domain that are enabled for single sign-on (SSO) without having to log in again.
  - Using Security Assertion Markup Language (SAML) to configure federated-identity authentication
    Federated identity is a means of achieving single sign-on, providing user convenience and helping to reduce administrative cost. In Domino® and Notes®, federated identity for user authentication uses the Security Assertion Markup Language (SAML) standard from OASIS.
  - Using a credential store to share credentials
    In this release, the on-premises Domino® server can use a credential store application (credstore.nsf). The credential store is a secure repository for document encryption keys and other tokens necessary for Notes® client users to grant access to applications that use the OAuth (open authorization) protocol. OAuth allows user credentials to be shared with compliant applications so that users avoid extra password prompts.
- Administering
  This documentation provides information about the administration tools for managing and monitoring IBM Domino® servers and databases.
- Tuning
  Use this information to improve IBM® Domino® server, Domino Web server, and messaging performance through the use of resource balancing and activity trends, Server.Load commands, advanced database properties, cluster statistics, and the Server Health Monitor.
- Troubleshooting
  This section describes how to find and solve problems with IBM® Domino® server and Administrator client.

Setting up Notes® and Internet clients for SSL authentication

You can set up Notes® or other Internet clients for server authentication to encrypt data and authenticate the server identity when connecting to an Internet server. You do not need an Internet certificate if you set up a client for server-only authentication.

On the server, SSL is set up on a protocol-by-protocol basis. You can choose to enable SSL on all protocols, or enable SSL on some protocols but not others. For example, you can enable SSL on mail protocols (IMAP, POP3, SMTP) and disable it for HTTP. You must also enable the port for anonymous access; otherwise, Domino® requires an Internet certificate or a name and password from the client.

To access an Internet server using SSL, clients must have:

Software, such as a Web browser or a Notes® client, that supports SSL.
A trusted root certificate from a Domino® or third-party certifier.
(Notes® client only) A cross-certificate created using the trusted root certificate for the Domino® or third-party certifier. The trusted root certificate is no longer necessary after you create a cross-certificate.

Note: Secure transactions are indicated by the use of the term https:// in URLs for SSL-secured sites. A browser user can specify this when initiating a secure transaction. More likely, the user will navigate to a login page, where it is necessary to log in with a name and password in order to access the secure Web page.
