Abstract

Content randomization techniques for thwarting malicious software attacks. In one example, a method comprises the following steps. Content is received at a randomizer module from a first computing device, the content having been retrieved by the first computing device in response to a content request by a second computing device. The content is randomly altered at the randomizer module to generate randomly altered content. Log information about the random alteration to the content is maintained at the randomizer module. The randomly altered content is sent from the randomizer module to the first computing device such that the first computing device is able to provide the randomly altered content to the second computing device in response to the content request by the second computing device. Further, the random alteration may be removed from reply content using the log information.

Dependent claims

A method, comprising:

receiving at a randomizer module from a first computing device content retrieved by the first computing device in response to a content request by a second computing device;
randomly altering at the randomizer module the content to generate randomly altered content;
maintaining at the randomizer module log information about the random alteration to the content;
sending from the randomizer module to the first computing device the randomly altered content such that the first computing device is able to provide the randomly altered content to the second computing device in response to the content request by the second computing device;
receiving at the randomizer module from the first computing device reply content received from the second computing device in response to the randomly altered content;
removing at the randomizer module the random alteration from the reply content using the log information;
and
sending from the randomizer module to the first computing device the reply content after removal of the random alteration.
