1. A computer-implemented method comprising: referencing, by an in-memory database engine, a zero-day security vulnerability to generate a parameter; communicating, by the in-memory database engine, the parameter to a streaming component; receiving, by the in-memory database engine, data harvested according to the parameter by the streaming component; processing, by the in-memory database engine, the data according to a ruleset to generate information relating to an exploit of the zero-day security vulnerability; storing, by the in-memory database engine, the information in an in-memory database; communicating, by the in-memory database engine, the information as an alert to a user and to others on a distribution list; generating, by the in-memory database engine, an updated parameter from the information; sending, by the in-memory database engine, the updated parameter to the streaming component; receiving by the in-memory database engine from the streaming component, updated data harvested according to the updated parameter, wherein: the updated data indicates a patch of the zero-day security vulnerability; halting streaming activity related to the zero-day security vulnerability by the streaming component upon receiving the updated data including the patch; processing by the in-memory database engine, the updated data according to the ruleset to generate updated information regarding another exploit of the zero-day security vulnerability, the updated information comprising an exploit code; storing, by the in-memory database engine, the updated information; and communicating, by the in-memory database engine, the updated information to the user, wherein the zero-day security vulnerability is fixed by referencing the exploit code in the communicated updated information.
