Predictive Heuristic Filter
 |
Heuristic prediction is an original concept developed by Vade Retro engineers.
It enables to answer to the problem of critical and necessary intervention period that publishers encounter when they face outbreak.

Unlawful viral attacks are more and more frequent and devastating. A few years ago needed days or weeks to go around the world. Nowadays a few hours is enough to infect millions of workstations. Trojans and worms have created a network which enable spam and viruses to spread all around the world very quickly.
Attacks are more and more devastating so antivirus publishers have to react more quickly. However there is always a critical insecurity period during which viruses and unwanted emails can spread through thousands of computers. This makes users angry, although they got active protection (see the schema below).
This schema represents insecurity period during virus outbreak.
Thanks to Predictive Heuristic Filter, Vade Retro protects users from the start of the attack.
Heuristic prediction enables to filter spam and viruses attacks without requiring any intervention or any update. Thanks to this, users are protected even during the insecurity period.
Looming systems which come by concealed doors to spread massively have a weakness: they focus on viral innovation or the visible content of the message. Creating infected emails requires techniques which evolve less quickly. Smart analysis and action on the message's structure are enough to block a virus-carrier message. To do this it is not necessary to analyse the infected file.
Developing the heuristic prediction system consists in keeping only the filtering rules which are based on unlawful emails sequences with a high reappearance probability. A rule become and may be considered as prédictive when it has been developed to answer specifically to an attack and it keeps on react to new ones.
Predictive Heuristic Filter forms a part of Vade Retro Technology and is available in all our software and hardware solultions.
