Linux server hardening
Linux server hardening
Hardening reduces the attack surface, tightens access control and improves audit readiness. Recommendations are prioritised by business risk and your infrastructure.
01
Priority controls
01
Access and authentication
SSH hardening, sudo policy and account policy.
02
Network exposure
Firewall policy and fewer services exposed to the network.
03
Patching and services
A patch baseline and unneeded services switched off.
04
Logging and auditability
Logging, audit trails and periodic configuration reviews.
02
Stages
Inventory
List servers, their roles and the services they run.
Baseline assessment
Current configuration compared with CIS Benchmarks.
Staged rollout
Changes tested in a non-production environment before they go live.
Verification
A fresh scan and documentation of the final configuration.
03
What you receive
- Baseline compliance report per server, before and after
- List of configuration changes with the reason for each
- Automation scripts or playbooks (for example Ansible) to apply the baseline
- Maintenance and periodic review guide
