Protective Hardening Techniques for Security+
Short answer
Protective hardening reduces the chance that routine exposure becomes compromise and improves the chance that suspicious behavior is seen or blocked. Encryption protects confidentiality and sometimes integrity depending on use. At this objective's depth, the purpose is to make stolen or intercepted data unreadable without keys. Full cryptographic solution selection belongs to cryptography objectives; here encryption is a mitigation technique.
Why it appears on the exam
SY0-701 2.5: Explain the purpose of encryption, monitoring, endpoint protection, host firewalls, host intrusion prevention, disabled ports/protocols, and default password changes.
Key concepts
Concept 1
How Protective Hardening Techniques works
Protective hardening reduces the chance that routine exposure becomes compromise and improves the chance that suspicious behavior is seen or blocked. Encryption protects confidentiality and sometimes integrity depending on use. At this objective's depth, the purpose is to make stolen or intercepted data unreadable without keys. Full cryptographic solution selection belongs to cryptography objectives; here encryption is a mitigation technique.
Example
Laptops use disk encryption so lost devices do not expose readable data. The mitigation is encryption.
Concept 2
Common confusion
Learners often confuse monitoring with an indicator. Monitoring is the control that observes. An indicator is the suspicious event observed. Learners also confuse host-based firewall and HIPS: host-based firewall filters host network traffic; HIPS blocks suspicious host behavior.
Example
Servers forward security events to a central platform for alerting and review. The mitigation purpose is monitoring.
Concept 3
What to recognize
Explain the purpose of encryption, monitoring, endpoint protection, host-based firewall, HIPS, and default password changes; Match a risk scenario to the most appropriate protective hardening technique; Distinguish monitoring as a mitigation from malicious indicators produced by monitoring; Unfair targets: requiring cryptographic algorithm selection, security information and event management (SIEM) rule syntax, endpoint product names, firewall command syntax, or HIPS signature authoring.
Example
Workstations receive endpoint protection to block known malware and suspicious behavior. The mitigation is installation of endpoint protection.
