Server Security, Hardening and Recovery Planning
Security and disaster recovery questions cover hardening, least privilege, network controls, encryption, physical security, backup strategies, RTO, RPO, and continuity planning.
How to study for CompTIA Server+
Treat each Server+ item as an operations decision: identify the server layer, protect data, read evidence, choose the safe next step, and verify health.
Core concepts
Concept 1
Server security layers physical controls, identity, patching, hardening, network filtering, encryption, logging, and monitoring.
Exam cue: Layer physical, logical, network, and monitoring controls.
Concept 2
Recovery planning requires backups, restore testing, redundancy, documentation, and clear RTO/RPO expectations.
Exam cue: Tie backup design to restore testing, RTO, and RPO.
Concept 3
Access control should be auditable, least-privileged, and aligned to the server role.
Exam cue: Use least privilege and audit evidence for access.
Risk pitfalls and guardrails
Assuming backup success means restore readiness.
Guardrail: Avoid answers that treat RAID as backup, replace parts too early, skip restore tests, over-grant access, or close without validation.
Leaving default or unnecessary services exposed.
Guardrail: Avoid answers that treat RAID as backup, replace parts too early, skip restore tests, over-grant access, or close without validation.
Granting broad admin access for routine tasks.
Guardrail: Avoid answers that treat RAID as backup, replace parts too early, skip restore tests, over-grant access, or close without validation.
Memory anchors
Server Hardening
Server hardening removes unnecessary exposure and applies secure baseline settings.
Least Privilege
Least privilege grants only the access required for the approved task.
Network Segmentation
Network segmentation limits lateral movement and scopes server access.
Encryption At Rest
Encryption at rest protects stored data when keys are managed properly.
TLS
TLS protects data in transit and depends on valid certificates and trust chains.
Backup Schedule
A backup schedule defines when and how data is protected.
Restore Test
A restore test proves backup data can meet recovery needs.
RTO
Recovery time objective defines how quickly a service must be restored.
RPO
Recovery point objective defines how much data loss is acceptable.
Business Continuity
Business continuity planning keeps essential operations running during disruption.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
