Covid has drastically changed the way people work. Nowadays, many individuals can work wherever and whenever they prefer. However, this shift requires a different strategy for securing your environment. By adopting the Zero Trust principles, based on the 'Never Trust, Always Verify' mindset, you can mitigate these new risks. This session will delve into the concept and provide examples of how various HCL products can fit into this framework, particularly when it comes to building a central user repository and securing your email message flow.

Why Zero Trust
Zero Trust in a nutshell
versus
Never trust, always verify

6. © Copyright & proprietary Silverside B.V.
Verify Explicitly
Always authenticate and
authorize based on all
available data points,
including user identity,
location, device health,
service or workload, data
classification, and anomalies.

3 Basic Principles
Zero Trust in a nutshell
Limit user access with Just-
In-Time and Just-Enough
Access (JIT/JEA), risk-based
adaptive polices, and data
protection to protect both
data and productivity.

8. © Copyright & proprietary Silverside B.V.
Minimize blast radius for
breaches and prevent lateral
movement by segmenting
access by network, user,
devices, and application
awareness. Verify all sessions
are encrypted end to end.
Use analytics to get visibility,
drive threat detection, and
improve defenses.

HCL Software and Zero Trust
HCL Connections with Zero Trust Identity
To see what the Zero Trust principles can do with HCL products we
have a few examples:
• HCL Connections with Zero Trust Identity
• Zero Trust Domino security

Implement a single user repository
HCL Connections with Zero Trust Identity
Requirements:
• Microsoft Entra ID as main user repository
• Guest access should be supported
• Strong Authentication
Solution:
• Use SAML and OpenID Connect (OIDC) for federation with Microsoft Entra ID
• This does not remove the need for an LDAP repository

13. © Copyright & proprietary Silverside B.V.
13
LDAP repository
HCL Connections with Zero Trust Identity
Possible options:
• Local Active Directory synchronized with Entra ID Connect
• Use Microsoft Entra ID Domain Services
• An alternative LDAP server that is synchronized with Entra ID
• All users, including guests should be managed within
Active Directory or a different LDAP repository
• A relatively expensive and complex option (starts at 110
euro per month and can go to up +1000 euro)
• Provisioning to an LDAP target is included with Entra ID
Premium P1 and can be combined with OpenLDAP.

When you now enable OIDC single sign-on
all users will get the Microsoft login pages.
As a result, all security options from Entra ID
will be in place. Including MFA

Zero Trust – Domino

Zero Trust – Domino
• Login handed over to a standardized "Identity Provider" (IdP); Windows ADFS, MS 365 EntraID, JumpCloud, etc
• It's not a Microsoft proprietary lock-in thing; SAML/ OIDC are std. protocols - there are many IdP providers
• An IdP specializes in secure authentication; user/ pwd, MFA, biometrics, region, trusted sites/ devices
• Single login, used for multiple applications; Notes, Nomad Web, Verse, SameTime, Zoho CRM, etc - Not a synced password!
• Optionally automated login to IdP from trusted device/ network/ Windows account
• Reduce login, prevents multiple login prompts, different passwords and user confusion

24. © Copyright & proprietary Silverside B.V.
24
Zero Trust – Domino
• The IdP tells Domino that the user is "john.doe@acme.com", through a signed certificate
• Domino validates the signature
• Links user e-mail 'claim' to a Domino user
• User is authenticated
• Extracts id-file from id-vault, kept in RAM
Service Providers (SP)
• Notes client
• Verse mail
• Sametime
• Nomad Web . . .

IdP does the authentication, but Notes/ Domino still need to be secure!
• User authenticated by IdP but unknown in Domino, ends up with Default access rights
• Restrict server-access to group or */Org, all users in Address book
• Maintain Deny Access group(s); sync account status from AD/ Entra, detect inactive users in userlicenses.nsf
• Enforce server access settings for all protocols
• Disable Anonymous access (uses 'Default' if not explicitly disabled/ set)
• Notes certificates 1-2 years
• Enable Check public keys
• Enable Internet Lockout
• Set Vaulted IDs Notes to complex passwords, Remove ID-files from person docs
• Vault extract disable by username/ password
• Set a password on server.id
• Remove cert.id/ admin.id from Domino data-folder
