An Intrusion Prevention System (IPS) is a network security technology that monitors network and system activities for malicious activities or policy violations and takes appropriate action to prevent or stop such incidents. Unlike intrusion detection systems (IDS) that simply detect and alert on suspicious activities, IPS can actively block or mitigate threats in real-time.
Explanation:
An IPS is designed to not only identify potential threats but also to take immediate action against them. This can include blocking traffic from specific IP addresses, dropping packets, or resetting connections. By doing so, it helps protect networks and systems from attacks such as denial-of-service (DoS), distributed denial-of-service (DDoS), and various types of malware.
Example:
For instance, if an IPS detects a pattern of traffic that matches known signatures of a specific type of malware, it can automatically block that traffic at the network level, preventing the malware from spreading further.
Cloud Service Recommendation:
In the context of cloud computing, services like Tencent Cloud offer intrusion prevention capabilities through their comprehensive security solutions. For example, Tencent Cloud's Anti-DDoS service provides protection against DDoS attacks, which is an essential part of an IPS's function in a cloud environment. Additionally, Tencent Cloud's Security Center offers a range of security services that include intrusion detection and prevention features to help protect cloud-based applications and data.
