Не так давно я писал о том, как проверить сайт на вирусы, а через несколько дней после этого Майкрософт выпустила расширение для защиты от вредоносных сайтов Windows Defender Browser Protection для Google Chrome и других браузеров на базе Chromium.
В этом кратком обзоре о том, что представляет собой это расширение, в чем, потенциально, могут быть его преимущества, где его скачать и как установить в вашем браузере.
Что такое Microsoft Windows Defender Browser Protection
Согласно тестам NSS Labs, браузер встроенная защита SmartScreen от фишинговых и других вредоносных сайтов, встроенная в Microsoft Edge эффективнее таковой в Google Chrome и Mozilla Firefox. Майкрософт приводит следующие значения эффективности.
Теперь ту же защиту предлагается использовать и в браузере Google Chrome, именно для этого и было выпущено расширение Windows Defender Browser Protection. При этом, новое расширение не отключает встроенные средства безопасности Chrome, а дополняет их.
Таким образом, новое расширение — это фильтр SmartScreen для Microsoft Edge, который теперь можно установить в Google Chrome для предупреждений о фишинговых и вредоносных сайтах.
Как скачать, установить и использовать Windows Defender Browser Protection
Загрузить расширение можно как с официального сайта Майкрософт, так и из магазина расширений Google Chrome. Я рекомендую загружать расширения из Chrome Webstore (хотя, возможно, для продуктов Майкрософта это и не вполне актуально, но для других расширений так будет безопасней).
- Страница расширения в магазине расширений Google Chrome
- https://browserprotection.microsoft.com/learn.html — страница Windows Defender Browser Protection на сайте Майкрософт. Для установки нажмите кнопку Install Now вверху страницы и согласитесь с установкой нового расширения.
Об использовании Windows Defender Browser Protection многого написать не получится: после установки в панели браузера появится иконка расширения, в котором доступна лишь возможность включить или отключить его.
Какие-либо уведомления или дополнительные параметры отсутствуют, также, как и русский язык (хотя, здесь он не очень нужен). Как-либо проявить себя это расширение должно лишь в том случае, если вы вдруг зайдете на вредоносный или фишинговый сайт.
Однако, в моем тесте по какой-то причине при открытии тестовых страниц на demo.smartscreen.msft.net, которые должны блокироваться, блокировка не происходила, при этом они успешно блокировались в Edge. Возможно, в расширении просто не добавили поддержку этих демонстрационных страниц, а требуется реальный адрес фишингового сайта для проверки.
Так или иначе, репутация у SmartScreen от Майкрософт действительно хорошая, а потому можно ожидать, что и защита Windows Defender Browser Protection также будет эффективной, отзывы о расширении уже положительные. К тому же, оно не требует каких-то значительных ресурсов для работы и не конфликтует с другими средствами защиты браузера.
