The DOs and DON'Ts of Domain Security

SECURITY DON'Ts...
QUÉ NO HACER

1. DON'T SAVE PASSWORDS
Never save your passwords in files, programs or web browsers.
No almacenes las contraseñas en ficheros, programas o navegadores.


2. DON'T MASK THE OWNER
If you are using a privacy service, ensure it does not mask the registrant (owner) of the domain. If your name is taken from you and the registrant was masked, this can cause problems when trying to prove ownership and recover the domain.
Asegúrate de que, al menos, tu nombre aparece en los datos del dominio. Es decir, privacidad al estilo Dynadot sí, pero al estilo Gordadi no.

3. DON'T USE FREE EMAIL
Never use a free email address such as Yahoo, Hotmail, or Gmail on your account or listed in your WHOIS data. These addresses can easily be hacked and your account compromised.
No uses un mail gratuito para registrar dominios.


4. DON'T KEEP EMAILS FROM YOUR REGISTRAR
Never leave any emails from your registrar in your email account, especially emails containing your login information. These emails should be forwarded to an email address that does not appear in the WHOIS and is not listed on your account. Make sure you delete your sent folder after forwarding the emails.
No guardes mensajes de los registradores, especialmente si contienen los datos de acceso.


5. DON'T RESPOND TO QUESTIONABLE EMAILS
Never respond to suspicious emails or click on suspicious links. If you receive a questionable email that looks like it is from your registrar, contact them to confirm the source before responding to the email.
No respondas a mail sospechosos ni hagas click en enlaces extraños. Contacta con tu registrador para confirmar su veracidad.


6. NEVER LET SOMEONE ELSE REGISTER YOUR DOMAINS
Always register your own domains.. Do not let a web designer or hosting company register your domains for you. Never give ownership or control of your domains to anyone.
No dejes que otros registren los dominios por ti (y pongan sus datos en él), ya sea tu hosting o tu registrador.

SECURITY DOs...
QUÉ HACER

1. DO GET INFORMED
Choose your registrar wisely. Before choosing a registrar, find out about their security processes and what their control panels offer in the way of security options.
Infórmate sobre el registrador a utilizar.

2. DO INTRODUCE YOURSELF
Make sure your registrar knows your business model. If you don't frequently transfer or sell domains, this information can help them identify suspicious activity in your account. Also, dealing consistently with the same account representative helps ensure they know you and your business.
Haz que tu registrador te conozca y sepa a qué te dedicas.

3. DO KEEP YOUR INFO UP-TO-DATE
Always ensure your account information and WHOIS information is up-to-date.
Mantén los datos del whois actualizados.

4. DO LOCK UP
Keep your domains on registrar lock and auto-renew, if offered by your registrar.
Pon los dominios en lock y autorenovación.

5. DO KEEP RECORDS
Maintain your own records outside of your registrar systems. Record all the domains you own, when they were registered, and where they were being managed. This information will prove useful if you need to prove ownership and recover your domains.
Haz un listado externo a tu registrador para llevar el control de los dominios que posees.

6. DO HELP YOUR REGISTAR HELP YOU
Provide your registrar with a copy of your company letterhead to keep on file. Many hijackings are attempted by sending forged faxes on fake letterhead. Having a reference point can help your registrar protect your account.
Que tu registrador tenga una copia de tu sello y datos fiscales. [no sabía cómo traducir esto ]

7. DO USE YOUR RESOURCES
Use all the security tools your registrar has made available to you. If you have the ability to prevent domains from being unlocked online, and to prevent automated authorization code retrieval, use these functionalities.
Utiliza todas las herramientas de seguridad que tu registrador ponga a tu alcance. Por ejemplo: no poder hacer el unlock online u obtener el auth-code de manera automática.

este seria algo asi como...
"Provee a tu registrador una copia de una hoja membretada de tu empresa para que la tenga en sus archivos. Muchos hijackings (robos de informacion) se intentan mandando faxes con hojas membretadas falsas, pero si el registrador tiene una original como punto de referencia podria ayudarte a proteger tu cuenta."
