Abstract

A trigger event monitoring system is provided in one or more virtual assets. One or more trigger parameters, including security threat patterns, are defined and trigger data is generated. The one or more trigger monitoring systems are used to monitor extrusion and intrusion capabilities and self-monitored trigger events that may harm or otherwise leave a virtual asset in a vulnerable state. In one embodiment, trigger events and monitoring of at least a portion of message traffic sent to, or sent from, the one or more virtual assets are initiated and/or performed to detect any message including one or more of the one or more of the trigger parameters. Any message meeting the one or more trigger parameters is identified as a potential security threat and is assigned a threat score, which is provided to the virtual asset. Various corrective actions may take place.

Claims

1. A system for virtual asset management comprising:

one or more processors; and

at least one memory coupled to at least one of the one or more processors, the at least one memory having stored therein instructions which when executed by any set of the one or more processors, perform a process including;

providing a cloud computing environment including one or more virtual assets instantiated and executing within the cloud computing environment by a computing processor, the one or more virtual assets comprising, at instantiation;

virtual asset self-monitoring logic, the virtual asset self-monitoring logic including data and instructions for detecting one or more trigger events of the virtual asset;

virtual asset self-reporting logic, the virtual asset self-reporting logic including data and instructions for generating trigger event reporting data if one of the one or more trigger events is detected in the virtual asset by the virtual asset self-monitoring logic;

self-reporting communications channel creation logic, the self-reporting communications channel creation logic including data and instructions for opening a self-reporting communications channel between the virtual asset and a virtual asset monitoring system responsive to one of the one or more trigger events being detected in the virtual asset by the virtual asset self-monitoring logic; and

trigger event reporting data transfer logic, the trigger event reporting data transfer logic including data and instructions for transferring the trigger event reporting data from the virtual asset to the virtual asset monitoring system if one of the one or more trigger events is detected in the virtual asset by the virtual asset self-monitoring logic;

detecting, by monitoring message traffic sent from the virtual asset, at least one message that satisfies one or more predefined trigger parameters;

classifying one or more portions of the detected at least one message as being suspect, the classified portions of the detected message satisfying the one or more predefined trigger parameters;

assigning a threat score to the suspect message at least partially based on a potential impact of the suspect message'"'"'s potential security threat on the virtual asset;

enabling, by providing the threat score to the virtual asset, the extrusion detection capable virtual asset to secure against the suspect message;

for each suspect message, generating suspect message copy data representing a copy of at least a portion of the suspect message; and

transferring the suspect message copy data to one or more analysis systems for further analysis.

2. The system for virtual asset management of claim 1 further comprising providing the virtual assets, at instantiation:

responsive action implementation data receipt logic, the responsive action implementation data receipt logic including data and instructions for receiving responsive action implementation data from the virtual asset monitoring system; and

responsive action implementation logic, the responsive action implementation logic including data and instructions for implementing the one or more responsive actions indicated in the responsive action implementation data received by the responsive action implementation data receipt logic.

3. The system for virtual asset management of claim 1 wherein at least one of the one or more trigger events is selected from the group of trigger events consisting of:

a network message from a virtual asset directed to a location known to be associated with malicious entities;

a frequency of outgoing network messages changing level above a defined threshold level;

a response to a customer request being directed to a destination that is not the customer location of record;

a virtual asset receiving a high-frequency of login attempts that fail;

a size of the parameters sent into a virtual asset being outside a defined range;

a size of outgoing network messages being outside a defined range;

a total amount of data in any one communication connection of a virtual asset exceeding a defined maximum;

a request to a virtual asset coming in from a location known to be associated with malicious entities; and

an internal elapsed time of defined critical operations changing to a time outside a defined range.

4. The system for virtual asset management of claim 1 wherein the suspect message copy data associated with a given suspect message is transferred to a specific analysis system of the one or more analysis systems for further analysis based, at least in part, on the specific trigger parameter of the one or more trigger parameters detected in the suspect message.

5. The system for virtual asset management of claim 1 wherein if, as a result of the further analysis at the one or more analysis systems, the suspect message is determined to be an extrusion related message, one or more protective actions are automatically implemented.

6. The system for virtual asset management of claim 1, wherein the virtual asset is a virtual asset selected from the group of the virtual assets consisting of:

a virtual machine;

a virtual server;

a database or data store;

an instance in a cloud environment;

a cloud environment access system;

part of a mobile device;

part of a remote sensor;

part of a server computing system; and

part of a desktop computing system.

7. The system for virtual asset management of claim 1, wherein defining one or more trigger parameters includes retrieving trigger parameters from an information management security vendor.

8. The system for virtual asset management of claim 1, wherein assigning the threat score includes assigning a number of a predetermined range of numbers to the suspect message, wherein a higher number is associated with a higher security priority.

9. The system for virtual asset management of claim 1, wherein providing the threat score includes delaying transmission of the threat score based on a priority of the suspect message.

10. The system for virtual asset management of claim 1, wherein assigning the threat score to the suspect message includes evaluating a service configuration to determine a vulnerability of the virtual asset.

11. The system for virtual asset management of claim 10, wherein the service configuration includes hardware characteristics of a host computing system for the extrusion detection capable virtual asset, and a type of information stored and provided by the virtual asset.
