Real-time detector of zero-day attacks on processor - Cyber Escort Unit The end justifies the means. It seems that today s processors follow this Machiavellian precept to achieve even more impressive performances. However, this has a critical negative impact on security by neglecting some basic recommendations on program execution. Despite huge efforts in the formal proof domain, secure coding is not so far at the easy reach of human nor machines, meaning that, by essence, a software code contains bugs. These software bugs represent however many breaches in cyber-protection constituting an abundant or even boundless source of weaknesses and attacks paths which cannot be predicted and giving rise to so-called Zero-Day Attacks . Structural protection allowing permanent alertness and long-term efficiency has to be preferred to Patch and Pray solutions, which are always too late and poorly efficient despite today common and standard at software level.
