Fachleute von Mozilla haben das Projekt WASI (WebAssembly System Interface) vorgestellt, das die Entwicklung von APIs f\u00fcr die Erstellung herk\u00f6mmlicher Anwendungen vorsieht, die au\u00dferhalb des Browsers ausgef\u00fchrt werden. Dabei steht anfangs die Plattformunabh\u00e4ngigkeit und ein hohes Ma\u00df an Sicherheit solcher Anwendungen im Vordergrund.<\/p>\n

\"Mozilla<\/p>\n

Wie festgestellt wurde, werden sie in einer speziellen \u201eSandbox\u201c gestartet und haben Zugriff auf Dateien, das Dateisystem, Netzwerksockets, Timer und so weiter. Dabei kann das Programm nur ausdr\u00fccklich erlaubte Aktionen ausf\u00fchren.<\/p>\n

Da der Pseudocode von WebAssembly eine plattformunabh\u00e4ngige Variante der Assemblersprache ist, erm\u00f6glicht der Einsatz von JIT eine hohe Code-Leistung, vergleichbar mit nativen Anwendungen. Derzeit ist eine Implementierung der grundlegenden POSIX-APIs (Dateien, Sockets usw.) verf\u00fcgbar, jedoch fehlt bisher die Unterst\u00fctzung f\u00fcr Locks und asynchronen Input\/Output. In Zukunft werden Module f\u00fcr Kryptographie, 3D-Grafik, Sensoren und Multimedia erwartet.<\/p>\n

Es ist auch erw\u00e4hnenswert, dass das Projekt Fastly einen Compiler namens Lucet f\u00fcr WebAssembly-Anwendungen vorgestellt hat. Dieser erm\u00f6glicht die sichere Ausf\u00fchrung von Drittanbieterprogrammen in WebAssembly innerhalb anderer Anwendungen, was beispielsweise f\u00fcr Plugins geeignet ist. Der Compiler selbst ist in Rust geschrieben und unterst\u00fctzt Code in C, Rust und TypeScript.<\/p>\n

Selbstverst\u00e4ndlich bleiben noch viele Fragen zur Sicherheit dieses Ansatzes. Die Ausf\u00fchrung von Code in der \u201eSandbox\u201c steht in einem merkw\u00fcrdigen Widerspruch zu dem Zugriff auf Funktionen des Hauptsystems, sodass dieses Thema weiterer Kl\u00e4rung bedarf. Au\u00dferdem ist unklar, welche spezifischen Programme in diesem Modus arbeiten sollen und wie ihr Verhalten \u00fcberwacht werden muss.<\/p>\n
