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.
  - Certificates
    A certificate is a unique digital signature that identifies a user or server. Server and user IDs contain one or more HCL Notes® certificates. In addition, user IDs may contain one or more Internet certificates that identify users when they use TLS to connect to an Internet server or send a signed S/MIME mail message.
  - Notes clients and two-factor authentication
    HCL Notes client authentication with a Notes ID provides built-in, automatic, two-factor authentication.
  - Password-protection for Notes® and Domino® IDs
    To ensure the security of the Domino® system, password-protect all Notes® and Domino IDs -- certifier, server, and user. When you password-protect an ID, a key that is derived from the password encrypts the data on the ID. Then, when you attempt to access mail, open a server-based database, or examine ID file information, you are prompted to enter a password.
  - The password quality scale
    When creating passwords for user, server, or certifier IDs, you need to understand the criteria by which Domino® measures password strength and security. Domino measures this criteria according to the level assigned on its password quality scale. The scale assigns a minimum level of quality to the password on an ID file. Domino bases the password quality on the number and variety of characters in the password.
  - Verifying user passwords during authentication
    You can enable password verification so that a Notes® user can authenticate with a server only after providing the correct password that is associated with the user ID.
  - Setting up password verification
    You can enable password verification through the use of a security policy settings document, which allows you to enable this feature for multiple users, or you can enable password verification on an individual basis through the Domino® Directory.
  - Custom password policies
    Information protection and data privacy laws include specific requirements for the selection of secure passwords for identity verification. To help users comply with these laws, HCL Domino® includes the ability to implement password restrictions on a policy basis. Administrators can enforce password requirements that will fit almost any set of corporate or government security requirements.
  - Assigning multiple passwords to server and certifier IDs
    To assign multiple passwords to server and certifier IDs, all of the administrators whose passwords will be assigned to the ID must be present. Then, during the procedure of assigning multiple passwords, each administrator completes a series of steps.
  - Using Notes® Shared Login to suppress password prompts
    Notes® Shared Login (NSL) allows users to start Notes without having to provide Notes passwords. Instead, they only need to log in to Microsoft™ Windows™ using their Windows passwords.
  - Using Nomad Shared Login to suppress password prompts
    Starting in HCL Domino 12.0.2, HCL Nomad Shared Login allows Nomad Web users to authenticate with Domino servers without having to provide Notes® ID file passwords after initial setup. This feature is enabled by default for Nomad deployments starting with Nomad 1.0.8.
  - Using Notes Shared Login to secure server ID files
    Starting with HCL Domino 12.0.1, you can secure the server ID files of Domino servers on Windows using the Notes Shared Login (NSL) functionality.
  - Notes® ID vault
    The ID vault is an optional, server-based database that holds protected copies of Notes® user IDs. An ID vault allows administrators and users to easily manage Notes user IDs. Users are assigned to a vault through policy configuration, and copies of user IDs are uploaded to a vault automatically once the policy has taken effect.
  - ID recovery
    Use of the ID vault for ID recovery is strongly recommended. However, the ID recovery feature described in this topic is still supported.
  - Public key security
    Every Notes® user ID and Domino® server ID has a unique public key for the Notes certificate. The public key is stored in an ID file and in the Person or Server document for that ID in the Domino Directory. Notes and Domino use the public key to authenticate users and servers, verify digital signatures, and encrypt messages and databases. A Notes user ID can also have a unique public key for an Internet certificate.
  - User and server key rollover
    Key rollover is the process used to update the set of Notes® public and private keys that is stored in user and server ID files. Periodically, this set of keys may need to be replaced -- as a precaution against undetected compromise of the private key; as a remedy to recover from a known compromise of the private key; or to increase security by updating to a larger key.
  - Certificate authority key rollover
    HCL Domino® administrators can assign a new set of public and private keys to a Domino certificate authority (CA). These keys are used to certify the keys of OUs, servers, and users in that organization. The process of assigning news keys is known as key rollover.
  - Using cross-certificates to access servers and send secure S/MIME messages
    Domino® uses both Notes® and Internet cross-certificates. Notes cross-certificates allow users in different hierarchically-certified organizations to access servers and to receive signed mail messages. Internet cross-certificates allow users to receive signed mail messages and send encrypted mail messages.
  - Adding cross-certificates to the Domino® Directory or Contacts
    You can use several methods to obtain an HCL Notes® or Internet cross-certificate.
- 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.
- 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.

Using Nomad Shared Login to suppress password prompts

Starting in HCL Domino 12.0.2, HCL Nomad Shared Login allows Nomad Web users to authenticate with Domino servers without having to provide Notes® ID file passwords after initial setup. This feature is enabled by default for Nomad deployments starting with Nomad 1.0.8.

You can disable Domino-based Nomad Shared Login deployment by completing the steps in the following section.

Disabling Nomad Shared Login

If you previously allowed or required Nomad Web users to use shared login but now want to prevent its use, edit the Security Settings document. Alternatively, you can remove users from the policy assignment or remove the Security Settings document.

In the notes.ini of the Administrator client, set $$TEST_NOMADSL=1.
Open the Security Settings document in edit mode and click the Password Management > Notes Shared Login tab.
Scroll down to Nomad Shared Login and for Enable Nomad Shared Login for Nomad Web, select No.
For How to apply this setting, select Set value whenever modified.
Save the document.

For Nomad for iOS and Android

HCL Nomad for iOS and Android clients that are configured using Nomad Federated Login honor the Nomad Shared Login policy setting. If Nomad Shared Login is enabled, then Nomad for iOS or Android will prompt the user to enable Nomad Biometric Authentication in order to securely save the user's Notes ID. If the user chooses to not allow HCL Nomad to enable biometric authentication or the policy setting is disabled, the client will re-download the user's Notes ID on every subsequent launch.
