Server hardening
Comprehensive hardening of your servers: optimised configuration, patch management and periodic audits to close the door before anyone tries it.
- Scope
- Linux and Windows Server
- Frameworks
- CIS Benchmark and vendor guidance
- Duration
- 2 to 4 weeks
- Follow-up
- Periodic audits
The problem
A freshly installed server comes open by design: services nobody uses, default accounts, weak encryption and broad permissions. Hardening means closing all of that without breaking what is genuinely needed.
What it includes
Comprehensive strengthening
Exhaustive hardening measures on every server, to ensure robust protection against known vulnerabilities and active threats.
Optimal system configuration
Tuning of operating system and application settings to meet security standards, minimising the attack surface and increasing resistance to intrusion.
Updates and patches
Proactive management of the patch cycle, keeping servers current to mitigate the risks arising from already published vulnerabilities.
Periodic audits
Regular reviews that assess whether the measures applied still hold and detect any emerging point of vulnerability.
How we work
- 01BaselineInventory of servers, exposed services and current configuration.
- 02HardeningApplication of controls with backup and a rollback window.
- 03VerificationComparison against the benchmark and proof that the operation still stands.
- 04AuditScheduled periodic review.
Deliverables
| Document | Length |
|---|---|
| Before-and-after report Status per server and per control. | included |
| Configuration guide A baseline for new servers. | included |
Note
No change is applied without a backup and a rollback plan. Hardening a production server with no way back trades a security risk for an availability risk.
