Scanning Engine v2 - Module - Memcached¶

Overview¶

Memcached is a high-performance, distributed memory caching system used to speed up dynamic web applications by alleviating database load. It is commonly used to cache data in memory and reduce the number of times an external data source, such as a database, needs to be accessed.

This module allows scanning with Memcached instances. It gathers all the stats information from the server.

Targeting¶

This module targets TCP ports by IP address or hostname.

Schemas¶
