Risk with Steganography and Importance of running Steganalysis with Network Systems

Published on

Malware protection

Steganography is an art of hiding messages covert way so that exclusive the sender and recipient know the original message.

This technique permits sender and receiver to communicate secretly and the third party won’t mindful of the correspondence happen.

It replaces bits of unused information into the standard files—graphic, sound, text,video—with some different bits that have been gotten surreptitiously.

What is Steganalysis

Steganalysis is the process of recovering hidden data, It decides the encoded hidden message, and if conceivable, it recovers that message.

The message can be identified by taking a gander at changes between bit designs and unusually large file sizes.This is considered to be an attack on the covered information.

Network steganography detection methods were somewhat developed independently from  IDS/IPS  systems Most steganalysis methods focus on trying to detect the presence of hidden communication and then on limiting its transmission capabilities,  because elimination of all network steganography opportunities is practically impossible.

Importance of running Steganalysis with Network Systems

A detailed scenario conducted by Trustwave security experts to identify the importance of running Steganalysis with Network Systems.

In the scenario, they consider an Employee who is having some confidential documents on his computer and if he sells that to another company he will at risk of consequences.

So he not find an alternative way, by using Stenography methods they may find a way to hide the document with the image to bypass Data loss prevention(DLP) filters and some other security tools.

We have to utilize a steganalysis module in our systems for preventing this kind of attack. The easiest approach is to run a steganalysis suite in one of our devices which analyzes the files that are attempting to leave the intranet.

Trustwave security said ,One of the problems that we have these days is that there are not a lot of tools that include steganalysis modules, so it is a little difficult to protect our networks from this kind of attacks. There are different tools for steganalysis but almost all of them require a person to manually use them.
