«DoS attack: Smurf» в логах роутера - стоит ли мне волноваться?

Question

Вот 2-дневный отфильтрованный журнал с моего маршрутизатора Netgear 6300. Кажется, у меня постоянно бывают SMURF-атаки.

Судя по моим настройкам роутера, я защищен. У меня "Отключить сканирование портов и защиту от DoS" не проверено.

Должен ли я быть обеспокоен?

Answer 1

Smurf:

Чтобы небольшими приращениями брать или отдавать субъекту.

Чтобы приготовить метамфетамин, наркоманы имеют "Смурфики", чтобы купить 2 коробки с простудой и синусом в день, пока их не станет достаточно.

(распределенный)DoS Attack:

Чтобы перегрузить сервер и отключить его, следовательно, "D" превращает службу в любого, кто подключается к серверу с законной целью.

Кто-то очень медленно забирает всю вашу пропускную способность и пытается рухнуть ... что-то. Вы запускаете веб-сервер? Если нет, то вполне возможно, что вредоносные программы заставляют ваш компьютер медленно выполнять DoS, как часть ботнета.
