Use of a Firewall

[Guest]

Archived from groups: comp.security.firewalls (More info?)

I currently know very little about firewalls, however I have been told
that if you're connected to the Internet then a firewall is a
necessity, is this true and what can go happen if you don't use a
firewall?

Thanks for any help.

I have a method which will cause your monitor to explode
in your face, not implode, but rather explode.

Another method I have renders your machine an Etch-A-Sketch.
Needs some fine tuning because keyboards lack knobs to turn,
leaving an exploited victim using arrow keys for drawing
dinosaurs, such as a T-rex.

Kick Ass Method

All methods and randomize your security responses to any given hack
which prevents fire-walking (profiling) your security systems.

Should you rely on machine security alone, it is almost guaranteed
you will have problems within one to two hours if connected to
the internet. Doesn't matter which operating system.

Be careful what you write and how you behave in newsgroups. There
are many whose only "life" is victimizing participants found in
newsgroups, _all_ newsgroups. There a lot of mentally disturbed
people out there, a lot of sociopathic people, even some who
will stalk and harass you in "real life" such as burglarizing
your home, as happened to us, perpretrated by a well known
psychotic over in the comp.lang.perl.misc newgroup. There are
a good number of sociopathic types in that group, and you can
be sure, completely sure, there are few here, as well.

Your internet security is not limited only to software; it also
includes dealing with those who will actually physically assault
your family, your friends, your co-workers and neighbors. This
I know based on true experiences.

Sounds very much like another cyber-friend aka T******.

Best method

system-security application-security common-sense-and-constant-education

Secure your operating system, and applications. Don't use, or leave activated,
any accounts with names or passwords with trivial values. Don't use an account
with administrative authority, except when you're intentionally doing
administrative tasks.

Use common sense. Yours. Don't install software based upon advice from unknown
sources. Don't install free software, without researching it carefully. Don't
open email unless you know who it's from, and how and why it was sent.

Educate yourself. Know what the risks are. Stay informed. Read Usenet, and
various web pages that discuss security problems. Check the logs from the other
security components regularly, look for things that don't belong, and take
action when necessary.
