    Revised security check

    Loungers might want to check out Steve Gibson's new & revised Port & Shields Up tester. It is much more extensive that the old version. It will test your firewall against many types of probes and give you a detailed report on how soundly it protects your system. I recommend it highly.
    You can use it at Shields Up

    Good peace of mind for the active Web surfer. <img src=/S/clapping.gif border=0 alt=clapping width=19 height=23>

    Long ago, there was a time when men cursed and beat on the ground with sticks. It was called witchcraft.
    Today it is called golf!

    Re: Revised security check

    Good pointer, Bob!

    I got cheesed off with Gibson because he never says how old the information is on his web pages. You get occasional clues, but no more. I suspect much of it goes back to the beginning of recorded time!

    John,

    You are right.
    In some ways, Steve gets carried away and his intentions are far ahead of the results, but generally his site is worth a regular look.
    His latest <img src=/S/new.gif border=0 alt=new width=35 height=15> tests though are very good and I think his "Spinrite 5.0" HD restoration prog is excellent. ( though slow ) <img src=/S/sigh.gif border=0 alt=sigh width=15 height=15>

    I tried this at work, and only the SMBP (did I get this right??!!) port was accessible.

    At home, using Microsoft's XP Firewall, it gave a perfect score of no failures. (Those Microsoft chaps sure know how to write firewalls!! <img src=/S/aflame.gif border=0 alt=aflame width=16 height=16> <img src=/S/cauldron.gif border=0 alt=cauldron width=20 height=20>)

    Re: Revised security check

    John,

    Do you mean SMTP? SMBP is one of our loungers. <img src=/S/smile.gif border=0 alt=smile width=15 height=15>

    SMTP is sometimes used as a "listening port TCPIP " for incoming mail managers, like Lyris List Manager or similar. I'm not sure if this SHOULD show as an open port or not. You may want to check with your IT people at work on this. ( or are you the IT person? )
    I use Zone Alarm here and it also shows a perfect "green board" score.

    Yes, you're correct -- I praise his posts so often that it must be in-built to type his name.

    I think the Microsoft XP firewall has been described as "one-way", because it's fine for preventing access FROM the outside, but quite happily lets rogue actions take place on your PC TOWARDS the outside if the PC has got compromised. ZoneAlarm would usually be my firewall of choice (although I see they have been having some fun with version numbers recently!!).


    We also have had fun with our work firewall, because to our considerable shock we discovered that we were acting as an Open Relay <img src=/S/blush.gif border=0 alt=blush width=15 height=15> but this has been plugged by a software upgrade. Why Shields Up! is showing the port as vulnerable I'm not sure, but I think it is definittely a false positive... I will get some trained bloodhounds onto the case! <img src=/S/snail.gif border=0 alt=snail width=21 height=17> Ooops! <img src=/S/puppy.gif border=0 alt=puppy width=396 height=35>

    Re: Revised security check

    Usually you stop relaying in the mail server configuration by restricting relaying to a range of IP addresses relevant to your network.

    You need to allow SMTP through the firewall or you'll stop receiving e-mail. However, you only need to allow it to your mail server and no other addresses.
