1. A method performed by a host for transmitting an alert message from a Security Alerting System indicating a potential compromise of a protected resource to a server, comprising:

  • obtaining, by at least one processing device of said host, said alert message from said Security Alerting System;

    authenticating, by at least one processing device of said host, said alert message using a secret key known by said server, wherein said secret key evolves in a forward-secure manner;

    storing, by at least one processing device of said host, said authenticated alert message in a buffer that is local to said host, wherein a size of said buffer is based on a connection history of said Security Alerting System, wherein said connection history comprises a time duration since a last connection with said server, wherein said size of said buffer is increased based on a number of time intervals that have passed since a last alert message transmission and an increment size of the buffer per time interval;

    storing a current write pointer index value and a forward secure counter indicating a number of buffer adaptations in said buffer; and

    transmitting, by at least one processing device of said host, said authenticated alert message from said buffer over a communication channel to said server.
