Master Big Data, Weak signals and APTs

As everyone admits today, the challenge of Cyber Security is to be able to identify weak signals and unknown threats in that vast amount of information available inside (i.e. in the company’s IT system) and outside (through various source of knowledge and threat intelligence).

Obviously, it looks like a typical Big Data situation. Hence, we all naturally tend to look for solutions similar to the ones that can be found in other domains where Big Data reigns.

Like a search engine, so helpful in our daily use of Internet: it looks like it is a valid answer to the Big Data issue we have in Cyber Security!

The same unconscious transfer happens with dashboards that are so helpful in Finance, Administration, Management, etc: it also looks like an appropriate answer to our Big Data issue.

There is however a huge limitation in the efficiency of the classical Big Data tools in Cyber Security: we are looking at threats and hackers that will adapt and evolve to take advantage of the particularities of your IT system and of its users. We are not talking about a generic, standardized threat. We are talking about a Cyber weapon that will specialize itself to target your positions on your battle field.

To handle such a threat, there is a pragmatic approach that is based on a very old advice to be found in Sun Tzu’s famous book named The Art of War. In this book, Sun Tzu promotes some principles and some concepts that structure good strategy to win battles. One of these principles states:

"Know the enemy and know yourself; in a hundred battles, you will never be in peril”

Sun Tzu

One concept associated to that principle is to be aware of the “terrain” where the battle is likely to take place. This immediately applies to Cyber Security, where observation and study of the information “terrain” are a necessity.

By regularly exploring its IT logs, one of our customers (in the chemical industry) got an intimate knowledge of how his network, services and users behave. Later, this knowledge and the ability of INENDI Inspector to ease the detection of anomalies made possible the identification of a subtle fraud that was taking place through one of its product-accounting servers in the production area.

For the same reasons, another customer could locate very quickly which machine in his networks had been infected after a successful DNS-amplification attack had happened on one of its servers, hiding injection requests to gain root access. The standard rules of the IDS were not capable of detecting the activity of the newly infected machines.

INENDI Inspector will help you get a deep knowledge of your IT system and master this Cyber terrain before your attackers.
