Study Notes
Intrusion Detection Systems
- A Host-based Intrusion Detection System (HIDS) monitors important operating system files.
Security Information and Event Management (SIEM) Systems
- The main purpose of a SIEM system is to collect, monitor, and analyze security-related data from various sources to provide a unified view of an organization's security posture.
Detection Approaches
- Signature-based detection relies on recognizing bad patterns, such as malware, by comparing network traffic or system files to a database of known malicious patterns.
- Anomaly-based detection uses machine learning to create a model of trustworthy activity and identifies anomalies that deviate from this model.
Anomaly-based Intrusion Detection Systems
- A potential drawback of anomaly-based intrusion detection systems is the possibility of generating false positives, which can lead to unnecessary alerts and waste resources.
Intrusion Prevention Systems (IPS)
- The main function of an IPS is to detect and prevent potential security threats in real-time, blocking malicious traffic before it can cause harm.
IDS vs IPS
- The main difference between Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) is that IDS detects and alerts, while IPS detects and prevents.
Network-based Intrusion Detection Systems (NIDS)
- A Network-based Intrusion Detection System (NIDS) monitors the inbound and outbound packets from an individual host or device on the network.
Traditional Network Firewall vs IDS
- The main difference between a traditional network firewall and an IDS is that a firewall blocks traffic based on predetermined rules, whereas an IDS analyzes traffic to identify potential security threats.
Signature-based IDS
- The detection method employed by a signature-based IDS is to compare network traffic or system files to a database of known malicious patterns.
Network Intrusion Detection System (NIDS)
- The purpose of a Network Intrusion Detection System (NIDS) is to identify and alert on potential security threats in network traffic.
