- G'day, this is Daniel Watson here
from Vertech IT Services
with cybersecurity tip number 40.
Today I'm talking about network security.
If you've got a business
and you've got a network connection,
you're providing guest
network access for wireless,
or you have tenants sub-tenanting out
some space in your offices,
or even if you just have contractors
who have their own kit who come in and out
of your organization, then
what you wanna think about
is segregating the
network so that they have,
there's a separate,
isolated network for guests,
and for those contractors,
and for any sub-tenants,
separate and distinct from
your own internal network.
Don't just get Internet connection,
get a cheap router from Vodafone
and then have everybody use
the same thing, all right?
Because you don't know if
their security policies
are anywhere near as tight
as what yours might be,
or what you're concerned with,
or if they have anything whatsoever.
So, and it doesn't take a lot of work
or effort to make this work.
For an example, I had a
client who was a rental agency
and they had a sales
consultant who would come in
on a temporary basis.
Every time that he came
into the organization
and did some work there,
they would find that
they were getting blacklisted
and they would have problems
sending out email, and scanning to email,
and actually just, you know,
they didn't get it while it was happening.
It actually took a while
for us to figure out
by looking at the firewall logs that,
you know, matching up the time of day when
this guy turned up, and
then we could actually
get onto his machine and then hack out
all the virus and stuff
that were spewing out crap
onto the Internet.
So it's a simple thing like that.
Doesn't take a lot of money,
but it's worth tightening-up
your network security.
Cheers.
