OT: Is Firewall necessary?

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
Is a software firewall such as Zone Alarm essential for added
protection if I am already using the XP firewall, AVG antivirus (free)
and have a wired router (D-link-524)? Will it offer me any additional
protection? If so, is there a better free firewall than Zone alarm?

Thanks.

The XP firewall and the router block incoming only, doesn't tell you anything
about what might be trying to call home.  Disable the XP firewall before
installing ZA.

As mentioned the Windows XP firewall blocks "inbound" threats, however if
something gets through and then connects "outbound" you wouldn't see the
activity.  A software firewall like ZoneAlarm (there's a freeware version),
or Comodo Firewall Pro (freeware) will show you all the outbound traffic in
detail.  In addition to having a lot more control you will learn a lot about
how your software is working, and develop a better understanding of system
security IMHO.  I use Comodo Firewall Pro as it has roughly the same
features as ZoneAlarm Pro.  The free version of ZoneAlarm doesn't give you
the same level of monitoring and control that the Pro version offers.

I'm looking at ZA and Comodo - what made you choose Comodo
over ZA (pro versions)?

You have to pay for ZoneAlarm Pro, and after the initial cost there is a
yearly renewal fee to stay eligible for updates.  Comodo Firewall Pro is
comparable to ZA Pro (I used ZAPro for years and then switched to CFP) and
is completely free for personal use.

An additional thought:  Some folks in this thread are saying that the
outbound monitoring that software firewalls like ZoneAlarm or Comodo
Firewall Pro provide is useless because once malware has infected your
system it can bypass the firewall.  That is not necessarily true.  I found a
Trojan on my system specifically because my software firewall blocked the
Trojan's outbound connection attempts and made me aware of it.  Security
software isn't perfect, but neither is malware.  A software firewall is a
useful component of a comprehensive security strategy IMHO.

It's not in "this" thread on some newsreaders since you changed the
subject title when responding to the OP and consequently framed me for
doing the same thing. Now I've got some misguided netcop on my tail.
:(

Jim, I honestly don't know why this happens.  I use Outlook Express (OE) and
I just click on the "Reply Group" icon when I respond to NG posts.  Normally
OE adds Re: to the front of the subject, but for some reason it is stripping
out the "OT:" of the original subject line (I tested and confirmed this by
creating a reply to the original post).  Perhaps this is caused by the use
of the ":" after OT?  I would be grateful if another OE user could test this
and let me know if it can be duplicated (it may be some setting specific to
my system).

In any case I apologize for any confusion this has caused.  I have manually
corrected the subject line of this message.



Re: OT: Is Firewall necessary?

I just hit "Reply Group" and as you can see, the OT is alive and well.
And I use OE needless to say.  So perhaps you were removing the "re" and
took out the OT as well??

It's a "feature" of OE. Any subject line starting with one to four
characters followed immediately by a colon and space will have that
sequence replaced by "Re: " when composing a reply.

That's the only way to fix it, apart from dumping OE.

Thanks - that's a big difference over time.

I hope you wouldn't mind one more question:  how much of a
drain does Comodo put on system resources, I'm more
concerned about cpu than actual memory although both are
significant.  I read a review somewhere that said Comodo
slowed the system quite a bit.

Thanks again.

Some figures I read from my Windows Task Manager:

firefox.exe  -  53.3562 kb
explorer.exe  -  18.880 kb
cpf.exe  -  14.300 kb
nod32krn  -  22.140 kb
svchost.exe  -  21.196 kb

I use Comodo after many years of ZAPro.
I have no problem with Comodo.

I'm running the latest version of CFP which is 2.4 (more precisely
2.4.16.174) and the XP task manager shows it using 25 megs of ram.  I don't
find that it slows my system down.  When apps are not accessing the internet
CFP.exe shows 0% cpu activity.  Since it's free why not just try it?



Re: OT: Is Firewall necessary?

FYI
Taskmanager shows Sygate as using 12700k on my W2K box, with 768mb total.

I wish more posters would offer this info on their posts, I am very curious.

The answer to that is no.

The additional feature of outgoing notification can't be considered as
"protection" since it relies on your machine already being infected
(or whatever you want to call it) before it comes into use.

With that in mind, you might find this notification useful for warning
you about valid programs like winamp sending out your profile
information, but any serious malware (because it is already running)
could easily bypass the notification in a number of ways leaving you
happy in the knowledge that you are being protected while your bank
account is being emptied.

Keeping an occasional eye on the router's flashing lights isn't a
waste of time if you can locate it in a place suitable for
observation.

Re: OT: Is Firewall necessary?

I'm wondering who made you the guru of OT for this group?

A firewall, in relationship to protection, if a valid subject for
protection from virus issues. Many firewalls can block virus code so
that the user never sees it.

Try not to be a dickhead all the time, Leythos. One person to
constantly harrass should be enough for you without having a go at me.

They're called av programs not firewalls and he already has one of
those.

I'm not going to get into an argument with a tosser like you about
whether a "security suite" program is a firewall, av, anti-spyware or
anything else. In my opinion, this fellow doesn't need some other
resource hog on his machine so you can shove your virus blocking
firewall up your arse.

Except that my firewall can actually remove viruses, and other firewalls
can actually remove files based on mime type - but, you don't appear to
be familiar with those.

Many quality firewall appliances have antivirus scanning features now,
and I'm not talking about software firewalls that people run on their
computers, I'm specifically talking about firewalls that have SMTP or
HTTP proxy services that can, in real time, detect and remove malware
before it reaches the users computer/network - we use these types of
firewalls in most installations.

So, you can shove your ignorance where you suggested that I do.

Like he's going to get one of those to run alongside AVG free in place
of xp firewall. lol.  Even Duane doesn't come up with such ludicrous
ideas. lol

And you missed the entire point of what I posted in that reply. Just
because someone brings up a question about a Firewall and AV solutions
does not make it off-topic, as you changed the subject to.

Again, there are firewall solutions, and I'm not talking about suites of
apps, that provide AV protection, and their discussion would be On
Topic. So, informing the user of viable AV solutions in firewalls would
be a On Topic thread.
