There's always the method connecting an intermediary hub on the switch port as well - if the switch doesn't have a spanning feature. I have a USB-powered hub glued to the back of the laptop for this very purpose. On 7/30/06, Murda Mcloud <murdamcloud () bigpond com> wrote:
If they're doing as much sniffing as you think then they'd prob pickup that your traffic is encrypted and start sniffing further. Encrypted traffic looks different to normal traffic. If they can't decode it\'read' it with ethereal then they will wonder why etc...and if it's part of their job then well, that's what they're meant to do...switches are one way of minimizing sniffing but even then spanning ports can get round this. -----Original Message----- From: cc [mailto:cc () belfordhk com] Sent: Friday, July 28, 2006 12:29 PM To: security-basics () securityfocus com Subject: Re: How to stop Admins from sniffing ? Didn't you write?: > I work in a small organisation and the system and network administrators here are constantly monitoring all data in the network. I have seen them running Etherreal on their systems and from their talks i am sure that they know who is doing what. I m using windows XP and i have a personal firewall installed which pop's up every few minutes saying that there is a port scan attack going on. And when i looked up that IP address it belongs to tbe system being used by the administrator. I have tried talking to my bosses about this but not happened ( maybe the admins convinced them that they are not doing anything like that or its happening by bosses permisson). i know since they are in same network as me its easy for them to sniff all traffic and everything. > This all depends entirely on your company's policies (computer or otherwise). Are the Sys and Net admins sanctioned by the management to administer these monitors? You are, after all, working in a company and not at home and thusly, you'd have to follow the rules and regulations as dictated by your company. I am assuming that the computer you are using is company property. In my company, employees are not told they can't bring their own notebooks; but they are strictly prohibited in plugging it into the company network. The moment they do that, it is a breach in the network. Also, by encrypting your traffic, and knowing your sys/net admins are watching, would you not think they'd suspect something is wrong and take it as their job to investigate the reasons for your secrecy? You are doing company-work, are you not? They know your job nature. If you feel that your job requires encrypted traffic, then it is in your best interest to talk to the sys/net admins and the management. > What i want to know from you ppl is that is there is anyway way to stop this ? > is it possible for me to encrypt all traffic going out from my system ? Take it up with the management and the sys/net admins. It really isn't our place to circumvent whatever computer system policies and protections you have going in your company.
