Router vs software firewall

Using a secure wireless router as my gateway, why would I need to use a

second software firewall, regardless of brand?

 

I browse to port-attacking sites and they can't even see me on the net, let

alone show a vulnerable port. Is there a further benefit from adding a

software firewall in this case?

 

All comments appreciated.

Since my first XP, I have only used a router and the Windows firewall. IMO,

for most, that is enough. YMMV.

Well, in a situation where a LAN has multiple machines, a firewall can

protect from prospective malicious traffic from those machine.

 

Also, should the machine get infected (a firewall cannot protect the

machine from a lot of malicious software), the firewall logs in the

machine can point to the problem and perhaps prevent unauthorized

outbound traffic.

 

But if the LAN is secure, or you have just one machine, then you are

okay with just the router firewall I guess.

A good choice is a combination of *WinXP Firewall* and a hardware router

with firewall features (wired or wireless).

(Steer away from any 3rd party (so-called) firewall software)!

 

It is suggested specifically blocking both TCP and UDP ports 135 ~ 139 and

445 on *any* SOHO Router.

If for any reasons you reverting back (temporarely or permanently) to

dial-up connection then in conjunction with WinXP SP2 Firewall use:

Seconfig XP 1.0

For added security you may wish to consider this:

For day-to-day work routinely use a Limited User Account (LUA).

Secure (Harden) your operating system.

Keep your operating(OS) system (and all software on it) updated/patched.

Reconsider the usage of IE and OE.

Don't expose services to public networks.

Routinely practice Safe-Hex.

Utilize a real-time anti-virus application and vital system monitoring

utilities/applications.

Keep abreast of the latest developments.

As long as you're behind a NAT router, that's probably enough if you're

not on 24/7. Since nothing is perfect and they play nicely together, I

still run a software firewall in addition to the NAT router's

capabilities. I find the SW wall quicker to tweak and get to so for

little things it's handy too.

If you use a router with NAT, it's still a very good idea to use a

3rd party software firewall. Like WinXP's built-in firewall,

NAT-capable routers do nothing to protect the user from him/herself (or

any "curious," over-confident teenagers in the home). Again -- and I

cannot emphasize this enough -- almost all spyware and many Trojans and

worms are downloaded and installed deliberately (albeit unknowingly) by

the user. So a software firewall, such as Comodo, Sygate or ZoneAlarm,

that can detect and warn the user of unauthorized out-going traffic is

an important element of protecting one's privacy and security, alerting

you to an unwanted malware application's activity. (Remember: Most

antivirus applications do not even scan for or protect you from

adware/spyware, because, after all, you've installed them yourself, so

you must want them there, right?)

 

When I ran WinXP, I used both a router with NAT and Sygate Personal

Firewall, even though I generally know better than to install scumware.

When it comes to computer security and protecting my privacy, I prefer

the old "belt and suspenders" approach. In the professional IT

community, this is also known as a "layered defense." Basically, it

comes down to never, ever "putting all of your eggs in one basket."

 

Having said that, it's important to remember that firewalls and

anti-virus applications, which should always be used and should always

be running, while important components of "safe hex," cannot, and should

not be expected to, protect the computer user from him/herself.

Ultimately, it is incumbent upon each and every computer user to learn

how to secure his/her own computer.

In addition to by original message it'd be worthwhile and educational if

you read the below mentioned articles. The authors Jesper Johansson and

Steve Riley are well respected and recognized for their in-depth knowledge

with respect to 'outbound protection' of 3rd party (so-called) firewalls.

Google for their credentials!
