Abstract

An example method includes detecting, using sensors, packets throughout a datacenter. The sensors can then send packet logs to various collectors which can then identify and summarize data flows in the datacenter. The collectors can then send flow logs to an analytics module which can identify the status of the datacenter and detect an attack.

Claims (37)

1. A system comprising:

one or more processors; and

memory storing instructions which, when executed by the one or more processors, cause the one or more processors to:

obtain network data from sensor processes executing in a data center, the network data being at least partly based on operation system states associated with an operating system in the data center;

store connection data describing a connection between endpoints associated with one or more packets transmitted in the data center;

determine a status of the data center based on the network data and the connection data;

detect, based at least partly on the status of the data center, an indication of an attack within the data center; and

in response to the indication of the attack, modify a security policy based on the status of the data center.

2. The system of claim 1 , wherein the network data comprises a respective indication of active or previously active processes on each of the operating system.

3. The system of claim 1 , wherein at least one of a log or the network data identifies files present on the operating system.

4. The system of claim 1 , wherein at least one of a log or the network data comprises data describing packets captured by the sensor processes executing in the data center.

5. The system of claim 1 , wherein the operating system is a virtual machine or a hypervisor.

6. The system of claim 1 , wherein detecting the indication of the attack comprises at least one of detecting a spike in an amount of resources used by at least one of the sensor processes or detecting spoofed packets.

7. The system of claim 1 , wherein detecting the indication of the attack comprises detecting a hidden process embedded in traffic between two or more reference points.

8. The system of claim 1 , wherein detecting the indication of the attack comprises detecting a scan of a network as initiated by a command from outside of the network or from an unexpected source inside the network.

9. The system of claim 1 , wherein detecting the indication of the attack comprises detecting a packet that has a packet header field that differs from an expected header pattern.

10. A method comprising:

obtaining network data from sensor processes executing in a data center, the network data being at least partly based on operation system states associated with an operating system in the data center;

storing connection data describing a connection between endpoints associated with one or more packets in the network data;

determining a status of the data center based on the network data and the connection data;

detecting, based at least partly on the status of the data center, an indication of an attack within the data center; and

in response to the indication of the attack, modifying a security policy based on the status of the data center.

11. The method of claim 10 , wherein at least one of a log or the network data comprises a respective indication of active or previously active processes on each of the operating system.

12. The method of claim 10 , wherein at least one of a log or the network data identifies files present on the operating system.

13. The method of claim 10 , wherein at least one of a log or the network data comprises data describing packets captured by the sensor processes executing in the data center.

14. The method of claim 10 , wherein the operating system comprises a virtual machine or a hypervisor.

15. The method of claim 10 , wherein detecting the indication of the attack comprises at least one of detecting a spike in an amount of resources used by at least one of the sensor processes or detecting spoofed packets.

16. The method of claim 10 , wherein detecting the indication of the attack comprises detecting a hidden process embedded in traffic between two or more reference points.

17. The method of claim 10 , wherein detecting the indication of the attack comprises detecting a scan of a network as initiated by a command from outside of the network or from an unexpected source inside the network.

18. A non-transitory computer-readable medium having stored thereon computer-readable instructions that, when executed by one or more processors, cause the one or more processors to:

obtain network data from sensor processes executing in a data center, the network data being at least partly based on operation system states associated with an operating system in the data center;

store connection data describing a connection between endpoints associated with one or more packets transmitted in the data center;

determine a status of the data center based on the network data and the connection data;

detect, based at least partly on the status of the data center, an indication of an attack within the data center; and

in response to the indication of the attack, modify a security policy based on the status of the data center.

19. The non-transitory computer-readable medium of claim 18 , wherein at least one of a log or the network data comprises a respective indication of active or previously active processes on each of the operating system.

20. The non-transitory computer-readable medium of claim 18 , wherein at least one of a log or the network data comprises at least one of information about files present on the operating system or information describing packets captured by the sensor processes executing in the data center.
