Security alerting system with dynamic buffer size adaptation

Abstract

A Security Alerting System is provided with dynamic buffer size adaptation. An alert message from a Security Alerting System indicating a potential compromise of a protected resource is transmitted by obtaining the alert message from the Security Alerting System; authenticating the alert message using a secret key known by a server, wherein the secret key evolves in a forward-secure manner; storing the authenticated alert message in a buffer, wherein a size of the buffer is based on a connection history of the Security Alerting System; and transmitting the buffer to the server. The alert message can optionally be encrypted. The buffer can be increased in proportion to a duration of a disruption of a connection. The size of the buffer can be increased by adding buffer slots at a location of a current write pointer index. Techniques are also disclosed for detecting truncation attacks and alert message gaps. The alert messages can have a variable size by writing alert message into consecutive buffer slots.
