[Astlinux-users] Securing Astlinux

[Cody A. <ald...@gm...>]

Hi,

I am connected to CNET (Collector's Network) and have one incoming VoIP
line running in Astlinux. Outgoing calls over the VoIP number have been
redundantly disabled in Asterisk and at the VoIP service providers setup
options. My Astlinux is constantly bombarded with attempts to get in by
unauthorized users. I currently have Adaptive Ban enabled, and, with help
already received here, have set the system to keep a record of the IP
addresses for the bans to persist after a reboot.

I was wondering what other security I should implement. Keep in mind that
the box is an older HP thin client, but the traffic is very minimal. I get
a lot more traffic trying to break in than the box needs to handle for
legitimate use. :)

If you suggest enabling another security feature, would you be so kind as
to point me to some instructions on configuring it?

Thank you in advance,

-Cody
