Detection Systems
Intrusion
Detection Systems (IDS) are critical tools used to safeguard a network by
continuously monitoring for suspicious activities or security policy
violations. They can analyse network traffic, user activities, and system behaviours
to detect potential threats in real-time, alerting administrators to take
action.
There
are two main types of IDS:
·
Host-Based
IDS (HIDS): Operates
on individual hosts or devices, monitoring system logs, file integrity, and
application activities to detect anomalies or unauthorized actions on that
specific device.
·
Network-Based
IDS (NIDS): Monitors
the entire network by examining packets of data transmitted over the network to
identify unusual patterns or signs of attack. It provides a broader view,
ensuring the security of the entire network infrastructure.
Access
Control and Auditing
Access
control involves setting permissions and policies to ensure that only
authorized users can access certain data or perform specific actions, minimizing
the risk of unauthorized access and potential breaches.
Auditing
systematically reviews and analyses logs and records of system activities to
detect any irregularities or security incidents.
By
employing access control measures to limit access and implementing regular
auditing to monitor and review system activities a robust security framework is
create to protect the systems from threats and ensures compliance with security
policies.
