&lt;br /&gt;
== Segurança Informática ==&lt;br /&gt;
“The protection afforded to an automated information system in order to&lt;br /&gt;
attain the applicable objectives of preserving the integrity, availability, and&lt;br /&gt;
confidentiality of information system resources” (includes hardware,&lt;br /&gt;
software, firmware, information/data, and telecommunications), in The&lt;br /&gt;
NIST Computer Security Handbook&lt;br /&gt;
&lt;br /&gt;
“Cibersegurança é o termo que designa o conjunto de meios e tecnologias&lt;br /&gt;
que visam proteger, de danos e intrusão ilícita, programas, computadores,&lt;br /&gt;
redes e dados.”, in Wikipedia&lt;br /&gt;
&lt;br /&gt;
== Segurança no sistema operativo ==&lt;br /&gt;
* Ter o sistema operativo actualizado;&lt;br /&gt;
* Instalar software de fontes fidedignas;&lt;br /&gt;
* Ter apenas um antivírus instalado;&lt;br /&gt;
* Ter sempre a firewall ligada;&lt;br /&gt;
* Atenção a pendrives que não conhece!&lt;br /&gt;
&lt;br /&gt;
=== Verificar a firewall ===&lt;br /&gt;
&lt;br /&gt;
== ANTIVÍRUS ==&lt;br /&gt;
“Obtivemos 554 votos válidos.&lt;br /&gt;
Então... “O melhor anti-vírus grátis para Windows” é...”&lt;br /&gt;
1. Microsoft Security Essentials (209 votos)&lt;br /&gt;
2. Avast Free Antivírus (110 votos)&lt;br /&gt;
3. AVG Antivírus (41 votos)&lt;br /&gt;
4. Avira Free Antivírus (36 votos)&lt;br /&gt;

&lt;br /&gt;
== WANNACRY ==&lt;br /&gt;
* Ataque massivo que se iniciou em Maio de 2017.&lt;br /&gt;
* Utilizou técnicas de phishing e uma vulnerabilidade de um serviço.&lt;br /&gt;
* Afectou e ainda pode afectar o sistema operativo Windows!&lt;br /&gt;
&lt;br /&gt;
O que fazer para prevenir?&lt;br /&gt;
* Desactivar o serviço SMBv1&lt;br /&gt;
* Não executar programas que estejam em pastas partilhadas na rede.&lt;br /&gt;
&lt;br /&gt;
== Segurança numa rede ==&lt;br /&gt;
* Nunca ligar a uma rede que não conhece.&lt;br /&gt;
* Nunca ligar a uma rede aberta (cibercafés... supermercados... shopping...)&lt;br /&gt;
* Se não for necessário, não active as partilhas na rede!&lt;br /&gt;
&lt;br /&gt;
== Segurança nos emails ==&lt;br /&gt;
Email... O meio mais utilizado para a distribuição de tudo e mais alguma coisa...&lt;br /&gt;
&lt;br /&gt;
SIM&lt;br /&gt;
* Enviar emails para uma grande lista utilizando o BCC &lt;br /&gt;
* Eliminar endereços antes de reencaminhar&lt;br /&gt;
* Utilizar certificados para encriptar e/ou autenticar&lt;br /&gt;
&lt;br /&gt;
NÃO&lt;br /&gt;
* Colocar em CC endereços de pessoas que não se conhecem&lt;br /&gt;
* Clicar em links que recebe nos emails de origem duvidosa&lt;br /&gt;
* Reenviar emails cuja origem é incerta&lt;br /&gt;
&lt;br /&gt;
Se o email possui dados importantes:&lt;br /&gt;
* Fazer backup periódico.&lt;br /&gt;
* Não deixar a conta aberta de forma a ser utilizada por terceiros!&lt;br /&gt;
&lt;br /&gt;
== Segurança nas passwords == &lt;br /&gt;
https://howsecureismypassword.net/&lt;br /&gt;
&lt;br /&gt;
Ao escolher uma password devemos tem em conta:&lt;br /&gt;
* Letras maiúsculas e minúsculas;&lt;br /&gt;
* Caracteres especiais;&lt;br /&gt;
* Números;&lt;br /&gt;
&lt;br /&gt;
Alguns sistemas não permitem o uso de todas possibilidades anteriores.&lt;br /&gt;
Outros sistemas obrigam ao uso de combinações especificas de caracteres.&lt;br /&gt;
&lt;br /&gt;
Problema: Estes sistemas estão inadvertidamente a reduzir o espaço de pesquisa&lt;br /&gt;
para ataques de força bruta.&lt;br /&gt;
&lt;br /&gt;
== Gestão de plugins e add-ons == &lt;br /&gt;
Verificar periodicamente os plugins instalados no browser.&lt;br /&gt;
Desactivar plugins que não utiliza ou que não foram instalados com consentimento.&lt;br /&gt;
Não instalar toolbars.&lt;br /&gt;
&lt;br /&gt;
== Certificados ==&lt;br /&gt;
Ficheiros que são utilizados para identificar e autenticar sites ou sistemas electrónicos.&lt;br /&gt;
&lt;br /&gt;
Contêm várias informações referentes aos respectivos donos.&lt;br /&gt;
&lt;br /&gt;
Possuem uma chave pública (conhecida por todos) que é gerada&lt;br /&gt;
a partir de uma chave privada (só do dono).&lt;br /&gt;
&lt;br /&gt;
=== Criação de um certificado para email ===&lt;br /&gt;
Permite autenticar e assinar digitalmente um email.&lt;br /&gt;
&lt;br /&gt;
Aceder ao site https://www.comodo.com e seleccionar Free Personal Email Certificate&lt;br /&gt;
&lt;br /&gt;
=== Certificados para sites ===&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Encriptação de documentos ==&lt;br /&gt;
Documentos confidenciais?&lt;br /&gt;
&lt;br /&gt;
Partilhados em rede?&lt;br /&gt;
&lt;br /&gt;
É necessário enviar por email?&lt;br /&gt;
&lt;br /&gt;
Querem implementar mais segurança?&lt;br /&gt;
&lt;br /&gt;
Solução: Utilizar um conjunto de chaves para encriptar&lt;br /&gt;
&lt;br /&gt;
=== GPG ===&lt;br /&gt;
Linux / Windows / Mac OS X:&lt;br /&gt;
* http://www.gnupg.org&lt;br /&gt;
* http://www.gpg4win.org&lt;br /&gt;
* https://gpgtools.org&lt;br /&gt;
&lt;br /&gt;
Gerar o par de chaves pública (necessário divulgar o mais possível) e privada (obrigatório manter secreta)&lt;br /&gt;
&lt;br /&gt;
Exportar a sua chave pública para formato texto para distribuir&lt;br /&gt;
&lt;br /&gt;
Fazer backup do porta chaves com as chaves pública e privada&lt;br /&gt;
 Colocar a sua chave pública num servidor de chaves&lt;br /&gt;
um documento.&lt;/div&gt;</summary>
