Opinions? Can you use both at the same time or does it create problems?

Hi Jedi ,
As a general principle, NEVER run two applications that do the SAME THING at the same time. You will have a high chance of resource conflicts. The really bad thing is that these may well be intermittent, and those sort of problems are a pig to troubleshoot :eek:
:)
Two would be bad. (and none would be better than one)
Increasing the complexity of a system decreases its level of assurance.
cheers,

None would be better than one? What do you mean?Quote:

I mean that firewalls should only be used for:
- Segregating network segments (fancy that)
- Monitoring/Filtering network content
- Tracking network accesses (for use in system isolation in worm/attack response)
Considering that application firewalls do none of these things, you are better off without them.
Close all unneeded services and use authentication mechanisms on services you'd like to control access to.
Operate the system as a non-privileged user to prevent the installation of malware.
Use the operating system's built-in networking filtering if you wish to control access to systems behind the system in question.
cheers,
catch
OK, this is a view I haven't heard yet... If I don't use a firewall, isn't that opening up my computer to attacks? Open ports, programs accessing ports I don't want them to? Everyone is always saying how you "need" a firewall... I'm a little confused. Thanks,Quote:

Well, as Catch seems to be offline right now I will attempt a reply.
1. The more applications you have running the less potentially stable your system is because there is a greater chance of resource conflicts, memory leaks and deadly embraces.
2. The more applications you are running, the more complex your system is, so the greater the potential for exploits etc. In other words, the less secure it is.
However, for an unsophisticated, non-networked home user situation, a software firewall is a reasonable solution. Provided that you remember that "firewall" does NOT equal "fireproof" ;)
OK, I think I'm beginning to understand... Now, what if I am online frequently, and gaming, and chatting? (and leaving downloads on all day...)
hmm...
If you have any questions about the above quote and as a home user, you're asking whether or not to use a firewall, then that is a good indication that you should.Quote:

Well I never do that.......................I have a very nice house, and I do not want it burned to the ground because of some scabby Chinese component defect. Also............I get to pay the electricity bill in this house ;)
I suspect that you should be looking at a hardware firewall, but I am no expert on them.
:)
The RIAA/MPAA might want to have a word about that :DQuote:

Well a hardware firewall, I.E a Router does take care of many things, but a software firewall is not a bad idea neither. A software firewall can detect if a program you might have installed/downloaded is trying to access the internet. Spyware for example, quite often connects to the internet to download more of its buddies...a software firewall, such as Norton's Personal Firewall, will warn you that the particular program is trying to access the web, and it will give you the options to Block it, or allow it.
I think running a hardware firewall, and a software firewall is not a bad idea. Remember though, unless you configure a firewall properly, its useless...
Cybr1d.
If your adding without altering a systems functionality you are reducing its overall security, and by lowering a systems assurance by needlessly adding multiple unwarranted firewalls you are broadening the surface-area for an attacker. (More code to work with and exploit.) Assurance is king, the more a given system has, the more secure it is. K.I.S.S
Your security must be accomplished at the OS level, not through applications and we all know how they get used in the end.
This WORD.doc below will give enlightenment on the aforementioned. It will tutor you on the history-types-generations of firewalls and what they are used for.

This is my understanding.
there is a HUGE difference between a fire wall and a router. You can creat rule sets and access lists on firewalls to prevent unwanted traffic, monitoring a traffic log will show the outbound connections from a computre so you can see and its pretty obvious if its legit or not.Quote:

I'm talking about a linksys, netgear, d-link...etc 4 port router sold in every computer store. They have a built in firewall.Quote:

actually most dont... SOME of them have it...like 1 in 10 models. and customers go for whats cheap not whats secure 90 percent of the time.Quote:

(as a side job I do business sales for one of the biggest national computer chains in the country, I have to sell this crap far too often.)
Most do (if not all). You'll find very few that don't have it and those that don't, are probably discontinued products that have been sitting on the shelf for too long. Again, i'm talking about routers aimed at home users, not businesses. As a full time job I sell networking supplies and other computer pheripherals, digital cameras/SLRs, Printers, Monitors, Computers and whatever else comes in your mind. www.microcenter.com will give you a list of items I sell ;).Quote:
