CASP+ Definitions: IDS, NIDS, WIDS
IDS stands for Intrusion Detection System, which is a security tool designed to monitor network or system activity for signs of unauthorized access, misuse, or other malicious activity. There are two main types of IDS: Network-based (NIDS) and Host-based (HIDS).
NIDS, also known as Network Intrusion Detection System, operates by monitoring network traffic and analyzing packets to detect suspicious activity such as intrusion attempts, malware infections, or other malicious behavior. It can be implemented using hardware devices or software applications installed on a server.
HIDS, on the other hand, monitors activity on individual hosts or servers to detect signs of malicious activity such as unauthorized access, malware infections, or system misconfiguration. It is typically installed on individual computers or servers, and can be used in conjunction with NIDS for more comprehensive security.
WIDS stands for Wireless Intrusion Detection System, which is a specialized form of IDS designed specifically for wireless networks. WIDS operates by monitoring wireless network traffic and identifying potential security threats such as rogue access points, unauthorized devices, or other malicious activity.
Overall, IDS/NIDS/WIDS are important tools for network and system administrators to detect and respond to potential security threats, helping to protect against data breaches, system compromise, and other cyber attacks.
