David Weston, vice-pr\u00e9sident de Microsoft responsable de la s\u00e9curit\u00e9 du syst\u00e8me d'exploitation Windows, a partag\u00e9 des informations sur le d\u00e9veloppement des m\u00e9canismes de protection de Windows lors de sa pr\u00e9sentation \u00e0 la conf\u00e9rence BlueHat IL 2023. Parmi d'autres choses, il a mentionn\u00e9 les progr\u00e8s r\u00e9alis\u00e9s dans l'utilisation du langage Rust pour am\u00e9liorer la s\u00e9curit\u00e9 du noyau Windows. De plus, il a \u00e9t\u00e9 d\u00e9clar\u00e9 que le code \u00e9crit en Rust sera ajout\u00e9 au noyau de Windows 11 peut-\u00eatre dans quelques mois, voire quelques semaines. <\/p>\n

Parmi les principaux motifs de l'utilisation de Rust, on cite l'impl\u00e9mentation d'outils pour un travail s\u00e9curis\u00e9 avec la m\u00e9moire et des efforts pour r\u00e9duire les erreurs dans le code. L'objectif initial est de remplacer certains types de donn\u00e9es internes C++ par des types \u00e9quivalents fournis par Rust. \u00c0 l'heure actuelle, environ 36 000 lignes de code en Rust ont \u00e9t\u00e9 pr\u00e9par\u00e9es pour \u00eatre int\u00e9gr\u00e9es au noyau. Les tests du syst\u00e8me avec le nouveau code n'ont montr\u00e9 aucun impact n\u00e9gatif sur les performances dans le test PCMark 10 (test des applications bureautiques), et dans certains micro-tests, le nouveau code s'est m\u00eame r\u00e9v\u00e9l\u00e9 plus rapide.

\"La<\/center> <\/p>\n

Le premier domaine d'application de Rust a \u00e9t\u00e9 le code DWriteCore, qui s'occupe du parsing des polices. Le projet a impliqu\u00e9 deux d\u00e9veloppeurs qui ont pass\u00e9 six mois \u00e0 retravailler le code. L'application de cette nouvelle impl\u00e9mentation \u00e9crite en Rust a am\u00e9lior\u00e9 la performance de la g\u00e9n\u00e9ration des glyphes pour le texte de 5 \u00e0 15 %. Le deuxi\u00e8me domaine d'application de Rust a \u00e9t\u00e9 l'impl\u00e9mentation du type de donn\u00e9es REGION dans Win32k GDI (Graphics Driver Interface). Les composants de l'interface GDI r\u00e9\u00e9crits en Rust passent d\u00e9j\u00e0 tous les tests lors de leur utilisation dans Windows, et le nouveau code devrait bient\u00f4t \u00eatre int\u00e9gr\u00e9 par d\u00e9faut dans les versions de test de Windows 11 Insider. Parmi d'autres r\u00e9alisations li\u00e9es \u00e0 Rust, on note le portage de certaines appels syst\u00e8me Windows vers ce langage.
