Who Looks at Firewall Logs?

By zczc2311 ·
Who Look in Firewall Logs

After 6 month at a quick analysis of a general MS office installation and Windows XP Pro SP2 of what ended up in SP2 firewall logs it became apparent that I could almost certainly bock the following Ports without causing any function change or pain to any application.

The following list must be seen as a guide only ? many who run legacy or cross platform applications may rely on ports contained in this list.

This list is published without warranty, but almost certainly most standard straight forward MS office installation will function without error and a home/office should feel no pain

If you have Web Servers, hopefully, these are shielded by a separate route away from office operational workstations

Ports designated as unassigned were at the time true and correct as of November 2004.

I hope this may help many ? trying to sort what to inhibit and offer a degree of security.

You've got it backwards.

by apotheon In reply to Who Looks at Firewall Log ...

The way to handle it is not to identify all the ports you don't need and block them: it is to block everything, then selectively unblock only the very specific ports you must have open.

Backwards??!!!!!!!!!!!!

With 65536 Ports good luck in doing it backwards

Yes, backwards.

by apotheon In reply to Backwards??!!!!!!!!!!!!

If you've got a firewall that forces you to hand-select every port you want blocked/closed/stealthed, you need a new firewall.

Functionality asside

by zczc2311 In reply to Yes, backwards.

Functionality aside ? as stated this list is a compiled audit of the most hits on the software firewall that were knocked back. It has been presented in a IANA format ? Ports associated with Service.

Functionally I can hardware block 1-65535 in about 2 minutes; however this is not the issue here.

It has been presented in such a manner that if others can see a required service, they leave that one alone.

Lets leave the functional application of this information as so.

The list was presented for IT staff to block these ports at a hardware level.

Blackjack Network needed here to join domain

by f18sim In reply to Functionality asside

Sorry for awaking an old thread but... I've been doing lot's of experiments on different reasons why machines don't join a domain and one of the ports that needs to be open is the Blackjack port 1025 tcp. I verified this through the pfirewall.log on the windows 2003 server. If that port is blocked the vista test machine I have will get the "RCP server is unavailable" error while trying to join the domain. RCP port 135 tcp is open on my firewall. So why does AD need the blackjack port anyway?

With 65,536 ports...

by TechExec2 In reply to Backwards??!!!!!!!!!!!!

.
With 65,536 ports, good luck in being secure from network threats by choosing the "right" ones to block and leaving all of the rest open.


The Short Career

Your office building has 65,536 doors. Some of them open into valuable areas, some open into areas you don't care about. Burglars are trying the door knobs on the doors every night. How does your security department know they've locked right ones unless they lock them all and keep a very short list of unlocked doors?

Security Chief: "Don't worry sir! I have implemented a great security policy where all 65,536 doors are kept unlocked except those on my list here."

CEO: "You're fired. And when you get to your new job, visit this link:".

I do

by The Listed 'G MAN' In reply to Who Looks at Firewall Log ...

in fact I have a dedicated screen with scrolling logs for all my firewalls shown.

Looks cool to the non IT user and every day I check the logs to make sure everything is as it should be..
