Detecting attacks on computing devices

1. A system comprising:

a first computing device comprising instructions executable by a hardware processor to:

transmit, responsive to detecting a second computing device initially attempting to connect to the network for a first time, an agent to the second computing device to generate log files of initial processes running on the second computing device during an initial operation time period of the second computing device, initial system calls made by the initial processes during the initial operation time period, subsequent processes running on the second computing device during a subsequent operation time period of the second computing device, and subsequent system calls made by the subsequent processes during the subsequent operation time period, wherein the initial system calls comprise initial programmatic requests of services from a kernel of an operating system executing on the second computing device, and the subsequent system calls comprise subsequent programmatic requests of services from the kernel;

create, responsive to detecting the second computing device initially attempting to connect to the network, an unpopulated baseline profile for the second computing device;

populate the baseline profile with the initial processes and the initial system calls;

monitor, during the subsequent operation time period, the subsequent processes and the subsequent system calls; and

detect an attack on the second computing device based on a comparison of the subsequent processes and the subsequent system calls to the populated baseline profile.

2. The system of claim 1 , wherein the instructions executable to detect the attack include instructions executable to detect the attack by identifying the subsequent processes and the subsequent system calls do not match a portion of the initial processes and the initial system calls.

3. The system of claim 1 , wherein the instructions executable to detect the attack include instructions executable to detect the attack by identifying a duration of the subsequent processes and the subsequent system calls do not match a duration of a portion of the initial processes and the initial system calls.

4. The system of claim 1 , wherein the instructions executable to monitor the subsequent processes and the subsequent system calls include instructions to monitor the subsequent processes and the subsequent system calls from a log file periodically received from the second computing device.

5. The system of claim 4 , including the instructions executable to assign a public-private key pair to the unpopulated baseline profile.

6. The system of claim 5 , including the instructions executable to detect that the log file is tampered with when the log file fails authentication.

7. A system comprising:

a first computing device comprising instructions executable by a hardware processor to:

create, responsive to detecting a second computing device initially attempting to connect to a network, an unpopulated baseline profile for the second computing device;

populate the baseline profile with initial processes running on the second computing device and initial system calls made by the initial processes during an initial operation time period of the second computing device, wherein the initial system calls comprise initial programmatic requests of services from a kernel of an operating system executing on the second computing device;

monitor, during a subsequent operation time period of the second computing device, subsequent processes running on the second computing device and subsequent system calls made by the subsequent processes, wherein the subsequent system calls comprise subsequent programmatic requests of services from the kernel of the operating system executing on the second computing device; and

detect an attack on the second computing device based on a comparison of the subsequent processes and the subsequent system calls to the populated baseline profile, wherein detection of the attack comprises identifying a duration of the subsequent processes and the subsequent system calls do not match a duration of a portion of the initial processes and the initial system calls.
