Opening all outbound ports will also alow peer-peer programs (like
Kazza, Napster etc) and Spyware which will consume *most* of your
So asside from the obvious security risks (tojans etc), you can also
watch your bandwidth go down, down, down.
Unless ofcourse, you work for an ISP/Telco ;)
Our firewall group has came to me several times over the last
wanting my approval to open all of the OUTBOUND ports on our
the internet. Their argument is that this would not
significantly reduce our
security and it will reduce their time/effort in administration.
they get several requests a week to open up out bound ports and
keeps growing each month. They want to go for the gusto
up all 65,000+
I am in the security area and they want my agreement/sign off
before they do
this. It just does not feel/smell right but I am losing
ground with my
arguments. What are some good arguments I can use?
