newest actual 2025/2026 with complete QUESTIONS AND
ANSWERS verified/GRADED A++
Information & Documentation Management
Protection and classification of physical and electronic
documents and data in IACS
Physical Security
Measures to protect personnel, hardware, networks, and data
from physical threats and events
Security Monitoring & Detection
Section in the Maintain Phase: Monitoring and detecting
abnormal activity and intrusions in network and hosts (IACS)
Network Intrusion Detection System (NIDS)
Device or software application that monitors network activities
for malicious activities or policy violations
, Where are Network Intrusion Detection Systems (NIDS)
commonly installed.
NIDS are typically placed at perimeters and other strategic
places on the network to scan inbound and outbound traffic.
Host Intrusion Detection Systems (HIDS)
Intrusion detection system that monitors and analyzes the
internals and network interfaces of a single host
Focus of Host Intrusion Detection Systems (HIDS)
Typical Focus of a HIDS:
- Virus and Malware Signatures
- File Integrity Checking
- Policy Monitoring
- Rootkit Detection
- Real-time Alerting and Active Response
Log Monitoring (LIDS) and SIEM
Security Log Analysis Systems are also known as Log-based
Intrusion Detection Systems and is the process or technique
used to detect attacks on a specific environment using logs as
the primary source of information. LIDS is often an integral
