Email security
The most destructive virus / worm
attacks on the internet are those that use email to propagate themselves.
The virus relies on users receiving an email from a known party to open an
attachments - which, unknown to them, contains a virus or worm.
At this point you are of course infected by the virus, and
the virus will then send a copy of itself to as many of the email contacts in
your address book as possible in order to infect more people.
Not only is it very embarrassing to infect clients,
colleagues and friends, but the virus may also contain a "payload" designed to
damage your PC - like making it run a lot slower to destroying information on
your hard disk.
Because spreading viruses by email is so effective, virus
writers favour this approach - making attachments you receive in your
email the single biggest computer security risk
that you are exposed to
on a daily basis.
Virus scanners
It is a common misconception that running a virus
scanner on your PC will protect you against this treat. Unfortunately this
is not true, because scanners look for known
viruses and worms.
They cannot protect you against
the hundreds of new viruses / worms developed every month.
So, contrary to popular belief, virus scanners are your last line of
defense - not the first.
Block everything - rather safe than sorry
Since the battle to keep track of new viruses and worms (before they cause
damage) is a non-starter, we developed a software solution that will protect you
against any new threat :
The Cozahost mail server blocks all executable attachments - regardless if it
can be positively identified as a virus / worm or not, and before it
reaches your inbox.
The advantages of this approach are:
- You don't have to spend the time to download the
virus before your scanner tells you that it is in fact a virus...and
then deletes
it.
- No executable program will reach your inbox at all -
so you are as close to 100% safe from emailed viruses or worms as it is
humanly possible to be.
- The sender of the mail (the "infected" person) is
automatically notified that (s)he tried to send an executable file (which is
probably a virus) - thereby providing a valuable early warning system
- You are notified of the attempted security breach
What if you need executable attachments to be sent?
It does happen from time to time that someone sends you a legitimate
executable file - perhaps a self-extracting .zip file or a demonstration
program, etc.
In cases like these both you (the recipient) and the sender are notified that
the email was blocked (and why).
The sender should now simply zip the attachment and email it to you
again...you can then decide whether or not you want to unzip and execute the
program.
You can of course also ask us not to block executable
attachments for your account at all - and take your own chances.
