Tentativa de invasão

Isso é uma das coisas mais importantes a ser considerada quando se coloca um site no ar.
Infelizmente SEMPRE haverá visitantes indesejados tentando forçar a entrada, explorando falhas do CMS, da linguagem PHP ou do servidor WEB (configurações da hospagem) e quando eles fracassam, apelam para o ataque DDOS.

A melhor forma de combater esse visitantes indesejados é impedir que eles consigam visitar seu site. Sem acesso ao site, não há como eles tentarem invadí-lo!

Existem plugins que utilizam uma tecnologia de DNS reverso, onde eles procuram o IP do visitante na bases de dados com a lista negra da internet e se o encontram, impedem que o mesmo consiga acesso ao site. É uma tecnologia que funciona e microsegundos, então não influencia no desempenho do site. Com isso, eu cortei 80% dos acessos que na verdade eram de tentativas de invasão ou spammers - principalmente da Rússia, China e Brasil ("eita povinho vândalo").

O primeiro baseia-se na base de dados do [url=http://projecthoneypot.org:1hm0ecwz][color=#0080FF:1hm0ecwz]Projet HoneyPot[/color:1hm0ecwz][/url:1hm0ecwz] e o segundo em várias bases de dados diferentes, incluindo também o [url=http://projecthoneypot.org:1hm0ecwz][color=#0080FF:1hm0ecwz]Projet HoneyPot[/color:1hm0ecwz][/url:1hm0ecwz]. No caso deste segundo, você não precisa usar todas as opções, combinar [url=http://projecthoneypot.org:1hm0ecwz][color=#0080FF:1hm0ecwz]Projet HoneyPot[/color:1hm0ecwz][/url:1hm0ecwz] com [url=http://stopforumspam.com:1hm0ecwz][color=#0080FF:1hm0ecwz]stop forum spam[/color:1hm0ecwz][/url:1hm0ecwz] cria uma barreira muito poderosa contra os visitantes indesejados.

Starting with some biographical data about Kate I would like to highlight some key [url=http://cirrdistprivlu198227.eklablog.com:33xbb6xh]http://cirrdistprivlu198227.eklablog.com[/url:33xbb6xh] information.

Of course I [url=http://fimibilfo197320.eklablog.com:33xbb6xh]http://fimibilfo197320.eklablog.com[/url:33xbb6xh] can't ignore that fact she is a celebrity, however we shouldn't also forgot how she became popular. Well, I cannot tell that women rule the world yet because this is not how it is, right [url=http://tophosnaito197522.eklablog.com:33xbb6xh]http://tophosnaito197522.eklablog.com[/url:33xbb6xh] fellows? One thing I can tell is that those photos of Isla Fisher naked are ruling my world and there is nothing I can do about it.
