  - 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 SSL 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 (NSL) 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 Notes® Client Single Logon to synchronize Notes® and Windows™ OS passwords
      You can use Notes® Client Single Logon to synchronize your Notes users' Microsoft™ Windows™ passwords with their Notes passwords, allowing them to use the same password.
    - 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.
  - 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.
  - 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 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.

Notes clients and two-factor authentication

HCL Notes client authentication with a Notes ID provides built-in, automatic, two-factor authentication.

The two factors for authentication are:

Something that you have The user has an encrypted file on disk containing the cryptographic credentials used for authentication to HCL Domino servers. The sensitive regions of that file are encrypted, including all of the private and secret keys.
Something that you know The user knows the password needed to decrypt the encrypted file. This password is never sent over the network to a server or stored on a server as part of authentication; it is used only to locally decrypt the encrypted ID file. Since V9.0, Domino administrators have been able to force end-users ID files to be encrypted using a 256-bit AES key generated per current security best practices using PKCS#5's PBES2 algorithm and iterated salted HMAC-SHA2.
