ADSL connected, is it open without loging-in?

My ADSL Broadband shows its connected, as soon as I start
the computer, but I need to log-in to get onto the
internet, does this mean that I am vulnerable to others
accessing my computer - even when I am NOT logged-on? I
do have ZoneAlarms free Firewall, McAfee Antivirus,
Spybot, Ad-Aware & pop-up stopper installed. My ISP says
I should only be on for 8 hours a day, not sure if this
is when logged-on or just when ADSL is connected? I just
want to be aware of the possibility that anyone can 'see'
my computer. I have only recently gone onto Broadband.

I imagine you are using a PPPoE client to log into your ADSL? If so, it
likely isn't running when you haven't logged in yet, so you aren't really
"connected" if so.
Your firewall and antivirus should be running resident in the background,
I'd think. Pop-up blockers won't matter when you aren't logged in anyway.
My ISP says

That's rather bossy and presumptuous of them!

In addition to your ZoneAlarm, I'd recommend getting a simple hardware
firewall/gateway appliance to put between your DSL modem & your computer. It
will do DHCP and NAT for you...and can log in to the PPPoE account using
your credentials, so your computer doesn't have to manage the work. A
NetGear FR114P (my current fave) is about $80USD, I think.
 
I use my DSL 24 hours per day, you are NOT limited to just 8 hours per day.

I suggest that you get a Cable/DSL Router such as the Linksys BEFSR41. It will act as a
simplistic FireWall and block activity before it reaches the computer. There are even
models that have full FireWall capabilities built-in. There are many other benefits to such
as a device such as being able to share the DSL WAN connection with upto 253 LAN nodes and
if you are using PPPoE as the DSL connector than the Router, not the PC, will make the DSL
connection and NO ISP provided software is needed.

a Floppy disk a hard drive :)
 
Thanks Dave,
Can I still use a DSL Router, if my ADSL Modem is inside
my computer, (not external, as a lot our)? If so, how do
I connect the router to the computer, or do I connect
from the Telephone line through the Router to the
computer? I do not need any LAN nodes what ever they are?
Also I need my ISP as I pay a monthly amount to receive
emails, as well as accessing the internet. I am limited
as I pay a cheaper amount for this, if I paid more, I
could be on for longer. It is only approximately 8 hrs.
Which is quite long enough for me anyway!
 
If you have a DSL Modem built into the computer you were screwed by your ISP. You can't use
an external Router.

Who is your ISP ?

I think I may be using a PPPoE client to log into my
ADSL? If it is the same as PPPoA?
Approx. 8 hrs a day, (with 2 GB month) is because I am
paying a lower monthly figure, if I paid more I'd me able
to be online longer, but this is quite enough for me,
anyway. What is a simple hardware firewall/gateway
appliance to put between my DSL modem & my computer. My
DSL is inside my computer, so how would I connect to it?
Why do I need DHCP and NAT? What do these do for me? I
only have one computer, no others.

I'm not a huge fan of Linksys stuff, but they, and Netgear, and Dlink, do
offer cheap & cheerful SPI firewall appliances. Not bad bang for the buck.

Yep.

What do they consider as "online" ? If you're connected but not doing
anything, does it count?

What is a simple hardware firewall/gateway
appliance to put between my DSL modem & my computer. My
DSL is inside my computer, so how would I connect to it?

It is??
Why do I need DHCP and NAT? What do these do for me? I
only have one computer, no others.

If you have a separate appliance, you have an additonal layer of security.

And if you look at most of their stuff (Netgear, D-Link), unless you
spend more than $200 it's just NAT with SPI.
 
My ISP is Wanadoo.com, which is who I was paying monthly
to on dial-up anytime, as have a website, wanted to keep
the same one. It was my choice to use my internal DSL
Modem, not my ISP, they have sent me an external one, but
not used it. Have no idea? if staying online, but not
using it, adds up the 8 hrs a day? Do not know what
would happen if I go over this!
Everything is working fine, so do not want to alter
anything, just wanted to know if I was online when my DSL
says its connected, but I haven't signed in (logged on).
Have received an answer from 'Lanwench' that I should not
be connected if using PPPoA client to log into your ADSL,
which I am.

Yep - which is a sight better than just NAT, which is all most of the cheap
& cheerful gateways do. One has to balance security & budget. Most home
users can't afford a PIX, or ISA, but that doesn't mean the appropriate
alternative is to use nothing at all.

As long as they don't start thinking they are firewalls then I don't have
a problem with them. In the early days all of the vendors called them
cable routers and then cable/dsl routers and then marketing got involved
and they started (without any firmware changes) calling them Firewalls.

They make great devices to protect from Inbound attacks, and that's what
most people need in order to get online safely, but it's not a firewall.

Sure. The word gets bandied about a lot, but SPI=firewall. "Acts as a
firewall" = NAT box.

If it's $30, it's probably the latter. If it's $80, it may well be a
firewall.

It still isn't anything an enterprise network would use, but it's a damned
sight better than just one's cable/DSL modem. And you can configure most of
the cheapies to block outbound traffic as well....the interface & features
just aren't as great as on higher end stuff.

Sorry, I just don't feel that adding SPI to a NAT box makes it a firewall.

Price also doesn't make or break it from being a firewall.

I agree that NAT is better than nothing, NAT+SPI is still even better, but
the combination does not make it a firewall.
 
And that's why I call it a Simplistic FireWall.

You should really learn to bottom post so that proper news readers can
work with your posts:

Simplistic is not an answer or excuse, it's either a firewall or not a
firewall, since it doesn't meet the requirements to be a firewall it's NOT
a firewall.

Those devices clearly meet the requirement to be a ROUTER, and are
performing routing functions only. It would seem that if they had stuck
with calling them ROUTERS instead of firewalls, that a lot of people would
not be mistakenly thinking they are protected by a firewall.

A router with NAT is not a firewall, a Firewall may include NAT, but NAT
does not make the firewall a firewall. You need to learn more about the
market before you start accepting that those SOHO devices are what they
claim to be.

I just don't blindly accept it. I have tested it. That is also why I suggest that TCP and
UDP ports 135 ~ 139 and 445 be blocked on *any* SOHO Router.

As for Bottom Posting, forget about it ;-)

Dave, I've tested every make and model that Linkys offers, most of the
D-Link line and the same for Netgear, in the under $250 range not one of
them is a firewall, they are all just ROUTERS.

Don't get me wrong, I like NAT Routers for the first line of protection in
a SOHO environment, but I will never confuse the simple functions of NAT
with those of a firewall appliance/device.

Not to get bogged down in a flamewar, no matter how gentle, a router isn't
really a router if it doesn't participate in RIP, is it. I call 'em
"routers" or, more appropriately, "gateway appliances".

"Firewall" is a fairly flexible term, but SPI is one type of firewall. I'm
pretty sure that Cisco is a fairly reliable source.

-----------------------
Stateful Inspection

Basic Definition:
The ability of a firewall to retain "state" information about
ongoing network sessions. When a packet goes out through a stateful firewall
(TCP/UDP/ICMP), it will only permit expected return traffic that would
normally be returned in response to that packet from the remote site. This
prevents a wide variety of attacks.
