Se acreditarmos nas estat\u00edsticas, cerca da metade dos sites foram alvo de ataques DDoS pelo menos uma vez no \u00faltimo ano. E essa metade inclui n\u00e3o apenas blogs iniciantes com pouco tr\u00e1fego, mas tamb\u00e9m sites s\u00e9rios de com\u00e9rcio eletr\u00f4nico ou recursos que moldam a opini\u00e3o p\u00fablica. Se n\u00e3o houver prote\u00e7\u00e3o para os servidores contra bots e acesso n\u00e3o autorizado, espere perdas significativas, se n\u00e3o o encerramento do neg\u00f3cio. A empresa ProHoster<\/a> oferece a voc\u00ea proteger seu projeto de alta carga contra ataques maliciosos.<\/p>\n

Um ataque DDoS \u00e9 um ataque de hackers a um sistema. O objetivo \u00e9 deix\u00e1-lo fora de funcionamento. Eles enviam uma quantidade enorme de dados para o site, que o servidor processa e acaba travando. Isso inclui conex\u00f5es criptografadas, pacotes de dados grandes ou incompletos de diferentes endere\u00e7os IP<\/a>. O n\u00famero de computadores em uma botnet pode ser de dezenas e centenas de milhares. Um sofredor n\u00e3o vence a batalha - lutar contra um ex\u00e9rcito desse tamanho sozinho \u00e9 simplesmente imposs\u00edvel.<\/p>\n

As motiva\u00e7\u00f5es para tais atos podem ser variadas - inveja, encomenda de concorrentes, luta pol\u00edtica, desejo de afirma\u00e7\u00e3o pessoal ou treinamento. Apenas uma coisa \u00e9 certa - \u00e9 necess\u00e1rio proteger-se contra esse fen\u00f4meno. E a melhor prote\u00e7\u00e3o \u00e9 contratar da empresa de hospedagem o servi\u00e7o de \"Prote\u00e7\u00e3o do Servidor contra Ataques DDoS\".<\/p>\n

A cada ano, fica mais f\u00e1cil e barato realizar ataques DDoS. As ferramentas dos atacantes est\u00e3o se aprimorando, e o n\u00edvel de organiza\u00e7\u00e3o deles deixa at\u00e9 mesmo os especialistas mais experientes perplexos. As travessuras de estudantes est\u00e3o se transformando gradualmente em crimes s\u00e9rios com planejamento cuidadoso. Essa \u00e9 uma forma de levar o sistema \u00e0 fal\u00eancia, sem deixar evid\u00eancias juridicamente v\u00e1lidas. N\u00e3o \u00e9 surpreendente que tais ataques ganhem popularidade ano ap\u00f3s ano.<\/p>\n

\"\"<\/p>\n

Prote\u00e7\u00e3o dos servidores contra ataques<\/h2>\n

Vale ressaltar que a grande maioria dos ataques DDoS \u00e9 realizada por equipes de hackers bem organizadas. Mas nossos filtros inteligentes de rede para limpeza de tr\u00e1fego de bots conseguir\u00e3o filtrar 90% do tr\u00e1fego malicioso e reduzir significativamente a carga no servidor. Isso \u00e9 poss\u00edvel gra\u00e7as ao uso de tecnologias em nuvem. A rede de filtragem de tr\u00e1fego \u00e9 composta por roteadores poderosos e m\u00e1quinas de trabalho que interceptam o tr\u00e1fego, distribuindo-o uniformemente entre si, filtrando e enviando-o ao servidor. Para o usu\u00e1rio final, isso pode resultar em uma pequena lat\u00eancia na velocidade de carregamento da p\u00e1gina, mas ele, pelo menos, conseguir\u00e1 acessar o site.<\/p>\n

Ataques fracos de at\u00e9 10 Gbps<\/strong> est\u00e3o inclu\u00eddos no pacote b\u00e1sico de qualquer hospedagem. Isso significa que eles s\u00e3o realizados por usu\u00e1rios inexperientes e n\u00e3o causam grandes danos. Mas se o ataque for mais s\u00e9rio, \u00e9 necess\u00e1rio conectar-se a recursos externos.<\/p>\n

Protegeremos seu recurso contra DDoS, SQL\/SSI Injection, Brute Force, Cross-site Scripting, XSS, Buffer Overflow, Directory Indexing gra\u00e7as ao uso de WAF (Web Applications Firewall). O dano causado por um ataque DDoS pode ser mais s\u00e9rio para o neg\u00f3cio do que o custo do pacote de prote\u00e7\u00e3o mais caro. Entre em contato com a ProHoster<\/a> agora mesmo, e tornaremos seu neg\u00f3cio na Internet \u00e0 prova de falhas.<\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
