Server administration, hardening, patching, and lifecycle management engineered for operational consistency.
Unpatched servers, inconsistent configurations, undocumented changes, and untested recovery procedures create operational risk that compounds over time.
HRHK provides server management that treats every server as a component of a larger operational system. We engineer consistency through configuration management, controlled change processes, systematic patching, documented procedures, and validated recovery capability—so your server infrastructure remains secure, stable, and recoverable.
Security foundations applied before exposure.
CIS benchmark alignment, unnecessary service removal, file system permissions, kernel parameter tuning, and security module configuration.
SSH key management, sudo policies, account lifecycle, privileged access boundaries, and administrative session logging.
Firewall configuration, service binding restrictions, egress filtering, and network segmentation for server environments.
Patching should be systematic, tested, and documented—not reactive.
Vulnerability Assessment
Identify missing patches
Patch Testing
Staging validation
Controlled Deployment
Phased production rollout
Rollback Planning
Recovery if issues arise
Documentation
Patch records, change logs
Exception Management
Documented deferrals
Consistency through automation, not manual effort.
Ansible, Chef, Puppet, or Salt for consistent server configuration, drift detection, and automated remediation across your server fleet.
Server inventory, configuration baselines, change records, and configuration drift reporting for operational visibility.
Backups that have not been tested are assumptions, not capabilities.
Backup
Full, incremental, differential, immutable
Test
Recovery validation, RTO/RPO verification
Recover
Documented procedures, orchestrated failover
Full, incremental, and differential backup strategies, offsite replication, immutable backups, and retention policy design.
Regular recovery validation, documented recovery procedures, RTO/RPO verification, and recovery runbook maintenance.
Server-level DR architecture, failover procedures, cross-site replication, and recovery orchestration for critical systems.
