1. Prerequisites and planning

Before installation, plan capacity, network layout, and authentication. Consider the number of endpoints, expected daily patch/download traffic, and integration with existing directory services.

• System requirements (example baseline; confirm with vendor docs):

  • OS: Windows Server ⁄₂₀₂₂ or supported Linux distribution.
  • CPU: 4+ cores (8+ for larger deployments).
  • RAM: 8–16 GB (16+ GB recommended for >1,000 endpoints).
  • Disk: 100 GB+ with fast I/O for patch repository and DB.
  • Database: Embedded or external MS SQL / PostgreSQL (size depends on retention).
  • Network: 1 Gbps recommended; ensure low-latency links to endpoints.

• Accounts and permissions:

  • Service account with rights to install services, write to installation paths, and connect to the DB.
  • Read access to Active Directory (if integrating) and appropriate firewall rules.

• Licensing and keys: obtain license files/keys from Cleartext.

2. Deployment options and architecture overview

Common architectures:

• Single-server deployment (small environments): server hosts application, database, and web console.
• Distributed deployment (medium/large): separate database server, application servers, and one or more distribution points (for patch/file hosting).
• High-availability setup: load-balanced application servers and clustered database.

Consider using distribution points in locations with limited WAN bandwidth to reduce cross-site traffic. Use VPN or direct networking between sites as needed.

3. Installing the Cleartext ESM Desktop server

Note: exact installer names and steps vary by product version; use vendor-provided installer/documentation for your version.

1. Prepare OS

   • Apply latest OS patches and harden the server per your baseline.
   • Install required runtime components (e.g., .NET runtime, Java, or other dependencies if listed).

2. Database

   • For production, choose an external database (MS SQL or PostgreSQL). Create a database instance and a SQL user with db_owner rights.
   • Configure DB settings for performance (max memory, tempdb settings for SQL Server, or tuning for PostgreSQL).

3. Install application

   • Run the Cleartext ESM Desktop installer as an administrator.
   • Choose installation directories; allow the installer to create service accounts or specify an existing one.
   • When prompted, provide DB connection details and test the connection.
   • Install the web console/management UI component and note the URL/port.

4. Repository and distribution points

   • Choose a repository location with adequate disk space.
   • Configure distribution points (local shares, SMB/NFS, or built-in distribution services) for remote sites.

5. Initial service start

   • Start the Cleartext services and confirm logs show successful startup.
   • Access the web console to continue configuration.

4. Configuring networking, authentication, and certificates

1. Firewall and ports

   • Open required ports between server, agents, DB, and distribution points (common: ⁄₄₄₃ for web UI, custom ports for agent communication).
   • Restrict access to management ports to administration networks.

2. SSL/TLS

   • Replace default/self-signed certs with a CA-signed certificate for the web console and agent communication to prevent MITM risks.
   • Configure certificate bindings in the application and verify chain trust on endpoints.

3. Authentication

   • Integrate with Active Directory (LDAP) or SSO (SAML/AD FS/Okta) for centralized user management.
   • Map AD groups to Cleartext roles (admin, operator, read-only).
   • Enable MFA on administrative accounts if supported.

4. Proxy and internet access

   • If agents or server need internet access, configure proxy settings and allowlist vendor update endpoints.
   • Test downloads of updates/packages through the proxy.

5. Deploying and configuring agents to endpoints

1. Agent preparation

   • Choose agent deployment method: MSI, GPO, SCCM, Intune, manual installer, or agentless (if available).
   • Configure agent installer options: server address, port, certificate thumbprint, service account or system context.

2. Deployment via GPO (example for Windows)

   • Create a shared network location for the MSI and transform (MST) if customizing.
   • Create or use an existing GPO, assign the MSI as a computer install package.
   • Target OUs containing the endpoints and force a GPUpdate to install agents.

3. Deployment via SCCM/Intune

   • Package the MSI with required properties and deploy as required to device collections/policies.

4. Validation and health checks

   • After deployment, verify agents appear in the server console and report healthy status.
   • Check agent logs on endpoints for connection, registration, and certificate trust errors.

6. Creating policies, groups, and patching schedules

1. Organizing endpoints

   • Create logical groups by function, OS, or location (e.g., Servers-US, Workstations-EU).
   • Use dynamic grouping where available (based on properties like OS, installed software).

2. Policies

   • Create baseline policies for patching, software deployment, and configuration enforcement.
   • Example policies: Critical updates immediate install, Monthly rollup after business hours, Software baseline enforcement weekly.

3. Patching schedules

   • Define maintenance windows for each group to minimize user disruption.
   • Configure reboot policies (suppress, scheduled, forced after grace period).
   • Test patches in a small pilot group before broad deployment.

4. Approval workflows

   • Use staging/approval for updates: pre-approve security patches automatically; manual approval for feature updates.
   • Configure rollback or uninstall options where supported.

7. Monitoring, reporting, and alerts

1. Dashboards
   • Customize dashboards to show patch compliance, agent health, and critical vulnerabilities.
2. Alerts
   • Configure alerts for failed deployments, offline agents, and high-severity vulnerabilities. Route alerts to email, webhooks, or SIEM.
3. Reports
   • Schedule compliance reports (daily/weekly/monthly) and export formats (PDF/CSV).
   • Use query or built-in reports to show missing patches, failed installs, and historical trends.

8. Backup, maintenance, and upgrades

1. Backups
   • Back up the database regularly and test restore procedures.
   • Back up repository configuration and critical application config files.
2. Maintenance
   • Monitor disk usage of repositories; clean up old packages per retention policies.
   • Rotate certificates before expiry and test renewal procedures.
3. Upgrades
   • Review release notes and pre-upgrade checklists.
   • Test upgrades in a staging environment; follow vendor rollback instructions.

9. Common issues and troubleshooting tips

• Agent fails to register:
  • Check connectivity, DNS, firewall, and certificate trust. Verify server address and port in agent config.
• Patches download slowly or fail:
  • Verify distribution points, proxy settings, and bandwidth throttling. Check repository disk space.
• Authentication/SSO issues:
  • Check time synchronization (Kerberos), certificate validity, and correct service principal names.
• Database connection errors:
  • Confirm network connectivity, DB credentials, and that DB service allows remote connections.

Check application logs on server and agent logs on endpoints for specific error codes; vendor documentation often maps codes to fixes.

10. Security and hardening recommendations

• Run services with least privilege service accounts.
• Apply OS and application patches to the management server itself.
• Use signed packages and enforce TLS for all communications.
• Restrict console access with RBAC and MFA for admins.
• Monitor logs and integrate with SIEM for anomaly detection.
• Regularly review and remove stale agents or unused distribution points.

Installation and configuration of Cleartext ESM Desktop require planning across infrastructure, security, and operations. Follow vendor-specific guides for exact installer flags and configuration screens, test changes in staging, and automate deployments where possible to scale safely.
