What is internet content adaptation protocol (ICAP)?
ICAP (Internet Content Adaptation Protocol) is a protocol designed for communication between proxy servers and their additional services. It is similar to the HTTP protocol and is primarily used for filtering and modifying data transmitted by reverse proxies. Through ICAP, proxy servers can be connected to various additional services, such as virus scanners or web application firewalls (WAFs), to ensure the security and integrity of data traffic.
Typically, virus scanners are connected to WAFs via ICAP to scan traffic in real time for malware and other threats. In addition, external filters and other WAF additional services can also be based on ICAP to enable filtering, analysis and modification of data streams.
ICAP allows proxy servers to dynamically access traffic and act according to defined policies and rules. This provides granular control over data flow, enabling organizations to enforce security policies and meet compliance requirements.
Overall, ICAP serves as an important interface for integrating security solutions into network environments and enables companies to protect their IT infrastructure from a wide range of threats. By leveraging ICAP, organizations can improve the security of their network while optimizing the performance and efficiency of their proxy servers.
The Airlock Gateway uses the ICAP as an interface to integrate additional components into your security solution.
