| | Hello Everyone,
I am setting up a wireless network for my house, im finally getting rid of the dial-up (cost justified it). My cable line will be installed soon, and I am going to wireless network it so my two desktop PCs can share the Internet access. I've heard the mysterious security issues, but most of them seem pretty obvious that you have to be ignorant to overlook, like changing the admin password on your router, etc.
Anyway, what I am getting at here is a question: do you have any tips for securing a wireless network?
Thanks!

I'm using a wireless connection right now, and though my experience, you must have a password protected network or else people will start connecting to your network and using your internet. I don't have many tips on securing it, I'm just the guy with the adapter. My mom's the one that set it up

best thing to do is firewall the sh** out of it and encryot it as well to make it more harder to get hacked into along with some good tracing problems and anti virus stuff as well.

Apart from firewall and antivirus, you need to protect the 'air' part. Most Access Points implements security based on WEP which is not a good solution but is better than nothing. Nowadays WEP can be cracked in minutes. New equipment show bring WPA, which is more convenient, to secure the network. Also you can buy adapters to support WPA. There is a good article that treats this topic in http://www.lanarchitect.net/Articles/Wirel...SecurityRating/. Hope this helps.

Hi Now a days its very hot topic all over the world "SECURITY ISSUES WITH WIFI NETWORK". I also use Wireless Network at my office. Dont know much about security but we are using WEP 128 bit encryption key which is given to me by my Network Administrator. I dont know how secure it is as 1 person already wrote in this forum that WEP keys can be hacked within a minute. I think i must inform my Network Adminitrator also. LOL. I suggest you search in Google regarding the WiFi Network security, i believe there is whole lots of material avaialble on NET regardiung this.

i think the best security you can have is by the config of your router ... some routers, like lynksys, allows you to generate a key for each machinge to verify if they are part of the web ... as long as i know there are a lot of problems of security for wifi ...

i think that if the wireless network is encrypted ... there will be no problem with it .. i didnt say that it's a bullet proof ... but it'll be definately much harder to retrieve data from it

I use a wireless network at home and at school. My recommendation is to do the following things 1. Change the admin password and username (if possible) 2. Set up 128 bit encryption on the router and create a code that is random but that you have recording somewhere that you will not loose. 3. Install a firewall (I use Norton Internet Security and it works great) on the computers to prevent anyone who might somehow get into your network from getting to your computer Hope these help

The attacker can use a WEP cracking tool (such as AirCrack or AirSnort) to discover your WEP key if he collects about 300-500 megabytes of data from your network. The best thing to do would be to buy 802.11g enabled wireless devices that can reach speeds (theoretically) up to 54Mbps, so data transfer between your two PC's should be way faster. 802.11g works pretty well on small distances, and it supports WPA (that can't be cracked yet, and allot of time will pass until someone figures out how to do it). So, the final checklist would be: 1) Change the default admin username and password on your router/AP 2) Enable WPA if possible, or the highest possible WEB encryption. 3) Use a firewall (such as Zone Alarm) and an antivirus program on both sides (safety first!) 4) Make sure that there are no cars or vans near your house with a bunch of geeks, sitting inside it, fiddling with their laptops and giggling about something.  (Just in case)

Thanks! Well, if you know the basic security of the cable networking it just the same... imagine that in your wireless you still have cable on it and setup the security. technically speaking wireless LAN works line cable LAN, the only issues here is that wireless can be in any places as long as your locations covered with your access point. But still you can set it up personally by modifying yo IP address, if you used HDCP maybe somebody can get you in and access your pc. wireless setup and cable setup almost the same thing it just technically remove the cable and put some receiver and transmitter device on it that makes two devices communicate to each other... Wireless fidility is know to be a safe wireless connection but still, those potential users of computer can still get you in no matter what connections you have... My suggestions for your setup is to personalize everything, your IP, your accesspoint must be limited to other and put some firewall as part of basic security setup.

I was told by my isp provider that simply hooking up my ethernet cable to the computer disables the wireless access,although I encrypted it too.Once these pirates get a hold of your signal they can eat up bandwidth like nothing. As a hobby I messed around with wire sniffing software before. It's easy enough to be patient to obtain the packets,but after that comes the hard part.Deciphering the code isn't easy.

Wireless sniffer
Wireless Network Security
I have a question asking for help
Is there any specific configuration I need to do in my PC to allow wireless network sniffing.
I have 2 PC on my table one a Compact Presario and the other Fujitsu Lifebook S Series.
The Fujitsu run XP professional 2002 service PAC 3 and the Compaq running XP home addition 2002 service PAC 3.
I am using an MSN sniffer which works perfectly great on the Compaq PC, but show only my local MSN on the Fujitsu one.
My question is what should I change in my Fujitsu wireless or security configuration to be able to monitor my network from the Fujitsu PC

QUOTE(Shackman @ Jun 28 2005, 10:09 AM) Anyway, wireless lans, the signals can be easily tapped into and encryption at a high encryption setting, it can take quite a while to for decryption. There for , it will slow down the network speed. Wired networks are the best, provided your wires don't get compromised too... Wireless LAN signals can ALWAYS be tapped, but if the network is encrypted, the received tapped material is a bunch of trash! You can't do anything with it! As I said before, switch to WPA if you are having second thoughts about WEP. WPA cannot be cracked yet. WiFi encryption systems are INTEGRATED in WiFi equipment, it does not use any system resources. In fact, it shouldn't cause any slowdowns at all! Unfortunately, some manufacturers didn't implement this technology very well, and that's the reason why some cheap equipment causes the network bandwidth to be 2%-5% slower than usual when encryption is on. QUOTE I still say CDs are the best method of transferring information... He wants to share his internet connection, I don't think running around with CDs from one computer to the other will aid him very well  . PS: You can always enable MAC address filtering, but if your network is unencrypted, an attacker can use a network sniffer to discover a mac address in the data that is sent over a network, and then change his mac address to be the same as the one that he discovered. By doing that, he can gain access to your network. Again: Use encryption! Oh, and hiding the SSID can cause allot of compatibility problems, because some devices require a SSID to connect to a wireless network. Besides, Air Snort can detect it anyway. If your network is secure, you've got nothing to worry about.

Yea...default settings and passwords can all be found in the user manual so it will make it very easy for a hacker to compromise your system. The worst thing is that the manuals can usually be found online. Sometime at the manufacturer's website or sometimes from peer-to-peer networks.... So, like the above poster said, your system is not secure if you use the default settings. Anyway, wireless lans, the signals can be easily tapped into and encryption at a high encryption setting, it can take quite a while to for decryption. There for , it will slow down the network speed. Wired networks are the best, provided your wires don't get compromised too... I still say CDs are the best method of transferring information... -Shackman

Thanks! If you are planning for wireless network security must be secured... Part of that security is by changing all the default settings of each hardware like your router. Don't ever use the default setting of each device, if you do so, then your security is not secured to tell you frankly. Try to avoid using the DHCP setup or set your router as the DHCP Server because if you do so, many can have access to the net using your connection. To make sure that everything are secured put some firewall and specify only the allowed IP to accessed your router. in short customized you internet connection settings. I have encountered before when I visit my friends office and opened up my notebook and I found out that I have internet. See, that what I am talking about, to limit unexpected users. Solution for this is really to customized everything, install the best firewall you know and don't used default setting for all hardware you are using...
