Abstract

Sanitizing passwords used in a shared, privileged account includes providing a password of a shared account to a user; identifying a first machine logged into using the password; determining when the first machine enters an inconsistent state; and modifying a memory area associated with the first machine to eliminate occurrences of the password in the memory area.

Claims

1. A computer-implemented method for sanitizing passwords, comprising:

providing, by a computer, a password of a shared account to a user;

identifying, by the computer, a first machine logged into using the password;

determining, by the computer, when the first machine enters an inconsistent state, including by determining that a predetermined time period has elapsed since a first memory area associated with the first machine was modified by replacing each occurrence of the password with a first predetermined recognizable marker;

in response to determining the first machine enters the inconsistent state, identifying, in the first memory area associated with the first machine, one or more occurrences of the password; and

modifying, by the computer, the first memory area associated with the first machine by replacing each occurrence of the password with the first predetermined recognizable marker in order to eliminate occurrences of the password in the first memory area.

2. The method of claim 1, further comprising:

receiving, by the computer, a request from the user for the password.

3. The method of claim 2, further comprising:

determining, by the computer, that the request originated from a second machine different than the first machine.

4. The method of claim 3, further comprising:

determining, by the computer, when the second machine enters an inconsistent state;

identifying, in a second memory area associated with the second machine, one or more occurrences of the password; and

modifying, by the computer, the second memory area associated with the second machine by replacing each occurrence of the password with a second predetermined recognizable marker in order to eliminate occurrences of the password in the second memory area.

5. The method of claim 1, wherein the first machine is one of a virtual machine and a physical machine.

6. The method of claim 1, wherein the first machine is a virtual machine and the inconsistent state is a virtual machine snapshot of the first machine.

7. The method of claim 1, wherein the inconsistent state is an operating system crash.

8. The method of claim 1, wherein the inconsistent state is an application crash.

9. The method of claim 1, further comprising:

identifying in the first memory area one or more occurrences of the first predetermined recognizable marker; and

modifying, by the computer, the first memory area associated with the first machine to replace occurrences of the first predetermined recognizable marker with the password.

10. A system for sanitizing passwords, comprising:

a computer processor; and

a memory in communication with the computer processor storing instructions that when executed by the computer processor;

provide a password of a shared account to a user;

identify a first machine logged into using the password;

determine when the first machine enters an inconsistent state, including by determining that a predetermined time period has elapsed since a first memory area associated with the first machine was modified by replacing each occurrence of the password with a first predetermined recognizable marker;

in response to the first machine entering the inconsistent state, identify, in the first memory area associated with the first machine, one or more occurrences of the password; and

modify the first memory area associated with the first machine by replacing each occurrence of the password with the first predetermined recognizable marker in order to eliminate occurrences of the password in the first memory area.

11. The system of claim 10, wherein:

the memory in communication with the computer processor stores further instructions that, when executed by the computer processor, receive a request from the user for the password.

12. The system of claim 11, wherein the memory in communication with the computer processor stores further instructions that, when executed by the computer processor, determine that the request originated from a second machine different than the first machine.

13. The system of claim 12, wherein the memory in communication with the computer processor stores further instructions that, when executed by the computer processor:

determine when the second machine enters an inconsistent state;

identify, in a second memory area associated with the second machine, one or more occurrences of the password; and

modify the second memory area associated with the second machine by replacing each occurrence of the password with a second predetermined marker in order to eliminate occurrences of the password in the second memory area associated with the second machine.

14. The system of claim 10, wherein the first machine is one of a virtual machine and a physical machine.

15. The system of claim 10, wherein the first machine is a virtual machine and the inconsistent state is a virtual machine snapshot of the first machine.

16. The system of claim 10, wherein the inconsistent state is an operating system crash.

17. The system of claim 10, wherein the inconsistent state is an application crash.

18. The system of claim 10, wherein the memory in communication with the computer processor stores further instructions that, when executed by the computer processor:

identify in the first memory area one or more occurrences of the first predetermined recognizable marker; and

modify the first memory area associated with the first machine to replace occurrences of the first predetermined recognizable marker with the password.

19. A computer program product for sanitizing passwords, comprising:

a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code for providing a password of a shared account to a user;

computer readable program code for identifying a first machine logged into using the password;

computer readable program code for determining when the first machine enters an inconsistent state, including by determining that a predetermined time period has elapsed since a first memory area associated with the first machine was modified by replacing each occurrence of the password with a first predetermined recognizable marker;

computer readable program code for in response to determining the first machine enters the inconsistent state, identifying;

in the first memory area associated with the first machine, one or more occurrences of the password; and

computer readable program code for modifying the first memory area associated with the first machine by replacing each occurrence of the password with a first predetermined recognizable marker in order to eliminate occurrences of the password in the first memory area.
