Spole\u010dnost Objective Development vydala Little Snitch for Linux \u2014 linuxovou verzi sv\u00e9ho zn\u00e1m\u00e9ho n\u00e1stroje pro kontrolu odchoz\u00edch s\u00ed\u0165ov\u00fdch p\u0159ipojen\u00ed, kter\u00fd byl dosud v\u011bt\u0161inou k dispozici u\u017eivatel\u016fm macOS. Nov\u00e1 varianta se neprezentuje jako prost\u0159edek k tvrd\u00e9 ochran\u011b syst\u00e9mu, ale jako n\u00e1stroj pro kontrolu soukrom\u00ed: ukazuje, kter\u00e9 aplikace a k jak\u00fdm uzl\u016fm se p\u0159ipojuj\u00ed p\u0159es s\u00ed\u0165, umo\u017e\u0148uje blokovat ne\u017e\u00e1douc\u00ed spojen\u00ed a sledovat historii s\u00ed\u0165ov\u00e9 aktivity.<\/p>\n
