I have set up the native firewall, within my laptop, from Micrsoft Essentials or ?. It might be associated with another program?
I ran a check from a site called 'Shields Up'. Of all the squares that are supposed to be green, there were few that were red, meaning a failure; thus my overall score from the site is that I failed.

I don't know what else I can do, if there are deeper rooted settings, or if the site doesn't exactly interface with the windows firewall for an accurate score?

I am coming here & posting this topic, in case there are other measures or "tricks" that I can perform, to assure that the firewall is doing its job?

Thanks for replies, ahead of time.

The biggest reason for having a firewall is to control who gets into your machine.  The biggest mistake users make is clicking on that interesting link you got in your e-mail.  The first thing the virus you just invited into your machine will do is disable any and all protection it finds, Anti-virus, firewalls, task manager, system restore, all the methods you'd use to prevent intrusion.

Knowledge and the ability to use it is the best defensive tool anyone can have.

No amount of security software is going to defend against today's sophisticated malware writers for those who do not practice safe computing and stay informed.

Thanks for the reply. I did go through 'How to configure Windows Firewall in Windows 7'. It failed the "sheilds up" test & the ports that were the issue were 80, 1025 & 1026. I don't know if this is really an issue? But will look on some of these other tutorials that you have posted, to see what I am missing?

I am careful about going into areas that are problems & do know that I am bound to hit one of those sites that will do me harm. At times, recently, I went to a couple of sites suggested from the forums at Bleepingcomputer, to get a couple of free pinball programs. All seems ok, with a couple of minor gliches; I can live with. The other issue that I will refrain from, unless I can find a manner to utilize, is 'Rojadirecta'; a site that allows for free prosports streaming. If not careful there, one is apted to click on an unentended link & get some pesky maladware.

 

Thanks again for the replies & I will follow advice so I keep a fairly clean machine. I know that if I keep from going on untreaded sites, I will be better off. Sometimes I am lead there by advice & it would be nice if I could get on one of those sites & get out of it, without crudding up my laptop?

First of all, it is important the know if your machine is connected directly to the Internet or not. One way to test this, is to look at the IP address of your machine (for example with the command ipconfig).

 

If you know what an IP address is, and how to determine the IP address of your machine, check if it is a Private IP address. If your IP address starts with:

10.*.*.*

172.16.*.* - 172.31.*.*

192.168.*.*

 

then it is a Private IP address. Otherwise it is a Public IP address (do not post your public IP address here).

 

If you have a Private IP address, then your machine is not directly connected to the Internet. Hence Shields Up is not reporting what it sees on your machine,

but what it sees on your network device (modem, router, ...).

 

If you have a Private IP address, and you want to address the "issues" listed by Shields Up, then configuring the firewall on your machine will not help.

You have to do this configuration on your network device (provided you even can do this).

 

Second, don't be afraid of a "Failed" result by Shields Up. Some issues detected by Shields Up are in itself no threat to your machine. For example failing the ping test.

 

So first determine if you have a Private or Public IP address, and then we'll take it from there.

Didier Stevens,

Thanks for the reply. My address starts as such ##.#.##.###  the 1st number is five; don't know if that means anything?

I haven't had too much trouble overall, in regards to attacks, but did get a bug not too far back & was greatful Bleeping computer was on hand to help with the issue.

 

I use a "secured" IPS & not a public IP. I haven't used this machine on a public since I moved from XP to Win 7.

 

If I have given too much info with the array I laid out & the number, please let me know & I will edit it out.

Then your IP address is a Public IP address, and it's important to have a properly configured firewall running on your machine.

The result you get on GRC are then relevant to your machine.

 

Just to be sure: you did check your IP address with a local command on your machine (like ipconfig), and not on a website like http://whatismyipaddress.com/ ?
