Intrusion detection systems (IDS) are specifically designed to monitor network traffic for suspicious activity and potential threats. They analyze the data packets passing through the network and can identify patterns that may indicate the presence of malicious activities, such as unauthorized access attempts or policy violations. When an IDS detects such behavior, it can alert administrators, allowing them to take appropriate action to mitigate potential security breaches.

The focus of an IDS is primarily on detection rather than prevention, making it a critical component in a layered security strategy. By being proactive in monitoring network traffic, an IDS can help organizations maintain heightened security awareness and respond quickly to threats, thus safeguarding sensitive information and maintaining the integrity of network operations.

Other choices, while related to network security, serve different purposes. Web application firewalls are specifically oriented towards protecting web applications from attacks like SQL injection or cross-site scripting, rather than overall network traffic monitoring. Network sniffer tools are used for analyzing packet-level data but do not inherently provide the threat detection capabilities of an IDS. Data loss prevention systems focus on preventing sensitive information from leaving the organization rather than detecting malicious traffic.
