The CBAC that he mentioned does give a small performance hit on any router. This is just due to the fact that you're doing all your processing in software and the more you do the more you slow your...

Even the most basic firewall or routing devices wouldn't have any problem handling the types of syn attacks mentioned by Opus00. The firewall or device will normally have a setting for the embryonic...

I've known about this SOX problem for a while... what I can't figure is why my company, which is making money hand over fist as the largest domain register in the world, would file to become public...

Ha ha, sorry about that... trying to be thorough :)

Ok, well.. lets talk firewalls v. routers. and then we can talk about the differences between their access lists.

A router is designed to do two things in a network, path determination and...

I don't know how helpful this is, but I've seen similar problems with files locking on apache servers. If ettercap is writing to that logfile.log is may not allow your filter to be accessing the data...

U stands for a destination unreachable pdu was received. Take a look here for more answers http://www.cisco.com/warp/public/63/ping_traceroute.html

Early symptoms, from my experience, are that...

Oh, and I advise checking out www.nessus.org and getting on the mailing list if you're serious about nessus. It's saved me a lot of troubleshooting time on my systems.

How about just leaving the firewall on and having the nessus box's IP given a permit tcp any (or similar statement) so that it can test all ports from external and not compromising the firewall. You...

Can you serve pages from your web server to machines on your network? This would let you know that the web server is fine. Is the problem just getting connected from external sites?

I know many...

Good question. If you're talking about specifically port based VLAN implementation then no, it will not fail. The VLANs will not communicate with each other without the use of a router. The problem...

RC,



You're right about the 127.0.0.1 never leaving the nic it's designed as the hardware loopback test and should never even touch the line.

I don't actually know the answer to your question. My experience with linux is limited to setup and deployment, not necessarily the security. I'm just wondering why you would pay for this "challenge"...

I like the thinking, but Java has to be installed on each machine that is running Java web pages. The normal means of what you're talking about doing would be to push a new java 1.5.1 version out to...

I'm wondering if anyone has seen this issue before and if there is a registry setting or global type fix for the problem. We're using a proxy.pac file to set IE for all of our user machines to...

I agree with sirdice... when my organization rolled our setup out about a month ago we had to consider any device that is not allowed to send traffic directly to the internet has to be completely...

We use the exact same type of system as you described but it's using SCM from Computer Associates. The goal is to keep our users proxying through the device so we can filter their internet for...

You're within the network that's probably the most common type of packet you're going to see. It's letting the hardware know how to communicate based on the logical IP address that it received, most...

Only problem I don't like about that article's assesment is that all that VPN's "interesting" traffic is applied after access lists (Cisco anyways). Meaning, if it's a dedicated Poing-to-Point VPN...

Did that recently change to only 7 days? I thought it was a longer wait on plugins before.

Dude.. if we give out the answers here how are we ever going to further the list's goals of world domina... i mean um.... help people to get on the list.

sign up at www.list.nessus.org for the mailing list. It's helped me out a lot with learning the system. The first thing they'll tell you to do is to get updated to 2.2.6, but they will still probably...

Ha ha,

I think that would be great... only problem is.. in one drive down half a mile stretch i came across 38 open access points. This school district is many many miles of city my whole map...

Hi all,


I have been asked to appear on our local cable channel for our schools to explain some of the security considerations for home users setting up wireless APs (see my charm and good looks...

I think everything else is relatively well covered so I'll just handle 4 for you.
