Solved Is Closing Port 80 for the sake of increased security good?

August 27, 2013 at 21:39:05
Specs: Windows 7
I've read all over the place that the most vulnerable port on one's PC is Port 80 -- and that this is the first port potential hackers scan for to see if it's open before they launch their attack. So . . . so I close this port just for the sake of increased security and, if so, how is the best way to go about this?

Thanks in advance!

Don't close port 80 or you won't be able to view any web pages - that's the default port used by web servers for HTTP traffic.

What you do is install a good third-party firewall which can block any unauthorised attempt to access your PC over the net no matter which port it is. The best free & bulletproof firewall is Comodo.

✔ Best Answer
Most routers come with a built in firewall and any half decent firewall will reject any unsolicited requests to port 80, unless of course you are hosting a web server. It is called state full packet inspection. Most SOHO routers have it as standard.

http://en.wikipedia.org/wiki/Statef...

A hackers cant do anything unless you have some malware on your computer that will respond to an incoming request.

A decent firewall can be configured to reject ICMP requests which is used by the ping command. Once ping requests are blocked your computer is to all intents and purposed is invisible on the Internet.

Try pinging 5.81.36.144 which is my IP address. You wont get a response even though port 80 may well be open. That is called stealth mode in most firewalls.

Check here to see how well configured your firewall is.

Hey, that's not nice. Someone changed the title thus making my humorous response here seem silly. People would be thinking 'ol Dave's finally lost it. (Finally?? LOL)

A hacker will find a computer with an open port 80 more attractive because it usually means the computer is a web server and providing more options for their activities. Such a server can't block port 80 because it is required for normal operation.

When scanning an IP address used by a computer with an active firewall there will be no response, just like there was no computer there. Hackers don't find this very interesting and move on.

"Don't close port 80 or you won't be able to view any web pages"

That statement doesn't make any sense.

The vast majority of people on the internet don't have port 80 open on their computer and are able to view web pages. I have a web server on my computer, which is currently not running so port 80 is closed and I'm able to view this page.

The OP's question is regarding inbound port 80 traffic, not outbound.

By default all of the common ports will be closed anyway, not that it matters much when using a firewall.

If you're behind a router, port 80 is mostly closed by default.
In addition, even if port 80 would be open, it doesn't hurt as long, as you are not running your own webserver on your computer.
And further more, when running your own webserver, you have to forward port 80 to your webserver, in the routers settings manually.

There is no need, for closing port 80 cause it's closed by default.

Indeed, Dave -- why **was** my question re-worded? It was neither improper nor indecent . . . Is having a sense of humor frowned upon on this site??

Well, not usually. We occasionally have some fun. I suppose a moderator thought the title wasn't descriptive enough, although it seemed fine to me. It certainly messed up my incredibly witty response!

It want me!

I suspect the title was amended to that it would make it easier for other people to find the thread in a search and then they wouldn't miss out on my incredibly informative response.

Sorry for the mis-information. I read it on a web page just on the day I posted my reply. Just proves you can't trust everything you read.
