Secure initialization of intrusion detection system
View Patent ↗Secure intialization for detecting intrusions is disclosed. The secure initialization includes receiving a behavior profile associated with an application and reading the behavior profile associated with the application. The secure initialization further includes monitoring execution of the application, according to the behavior profile. If the behavior of the application does not conform to the behavior profile, a message is issued indicating that the application is not conforming to the behavior profile. The behavior profile can be generated by a developer of the intrusion detection system, a developer of the application, and/or a third party developer. Additionally, the behavior profile is generated by executing the system on a reference computer system or by heuristic determination.
1. A method in a computer system for detecting intrusions during a bootstrapping phase of an intrusion detection system, the method comprising:
storing a behavior profile associated with an application, the behavior profile having been generated, prior to operation of the application on the computer system that detects intrusions during a bootstrapping phase of an intrusion detection system, by any one of:
executing the application on a reference computer system other than the computer system for detecting intrusions during a bootstrapping phase of an intrusion detection system;
heuristic determination; and
a combination of executing the system on the reference computer system and heuristic determination, and wherein the stored behavior profile is at least one of encrypted and digitally signed;
reading, with the computer system during a bootstrapping phase of an intrusion detection system, the stored behavior profile associated with the application;
monitoring execution of the application at the computer system during the bootstrapping phase, according to the behavior profile; and
if the behavior of the application does not conform to the behavior profile, issuing a message indicating that the application is not conforming to the behavior profile.
2. A computer readable storage medium storing computer instructions for detecting intrusions during a bootstrapping phase of an intrusion detection system, the computer instructions including instructions for:
storing a behavior profile associated with an application, the behavior profile having been generated, prior to operation of the application on the computer system that detects intrusions during a bootstrapping phase of an intrusion detection system, by any one of:
executing the application on a reference computer system other than the computer system for detecting intrusions during a bootstrapping phase of an intrusion detection system,
heuristic determination, and
a combination of executing the system on the reference computer system and heuristic determination, and wherein the stored behavior profile is at least one of encrypted and digitally signed;
reading, with the computer system during a bootstrapping phase of an intrusion detection system, the stored behavior profile associated with the application;
monitoring execution of the application at the computer system during the bootstrapping phase, according to the behavior profile; and
if the behavior of the application does not conform to the behavior profile, issuing a message indicating that the application is not conforming to the behavior profile.
3. A computer system capable of detecting intrusions during a bootstrapping phase of an intrusion detection system, comprising:
a first memory for storing an application;
a second memory for storing a behavior profile associated with the application, the behavior profile having been generated, prior to operation of the application on the computer system that detects intrusions during a bootstrapping phase of an intrusion detection system, by any one of:
executing the application on a reference computer system other than the computer system for detecting intrusions during a bootstrapping phase of an intrusion detection system,
heuristic determination, and
a combination of executing the system on the reference computer system and heuristic determination, and wherein the stored behavior profile is at least one of encrypted and digitally signed;
a monitor, communicatively coupled with the first memory and the second memory, for
reading, with the computer system during a bootstrapping phase of an intrusion detection system, the stored behavior profile associated with the application, and
monitoring execution of the application at the computer system during the bootstrapping phase, according to the behavior profile; and
a warning module, communicatively coupled with the monitor, for issuing a message indicating that the application is not conforming to the behavior profile.
