Your thoughts on my network security.
am 06.12.2006 12:48:50 von Jimmy White
Hi all,
Right, I have been reading up on wan/lan security and have setup what I
think is a secure environment and would like your opinions.
First I have a router connected to my cable modem, which is connected to a
second wireless router. I use one of the lan ports on the second router for
my Internet connection with a software firewall on my PC. The wireless part
of the second router has a 63 character, ascii, numbers random key using WPA
TKIP(PSK) for my laptop. Also when I'm doing online Banking I use VPN to
connect to my Banks site and they use SSL also.
For spyware, adware, malware and viruses I use spybot,ad-aware and AVG pro
edition.
I'm I secure enough ?

Can you use WPA2 or at least change TKIP to AES.
63 characters is max. Maybe somebody will hope that max key is used
(exeactly what paranoid unexperienced people do) so he might bruteforce
only 63 character keys. Change lenght for ex. 55, 57, 52 etc. If you
used key offered by Windows there is no symbols and capital letters you
should change that. So somebody will have to bruteforce higher range
(that will take too much time). If you are home user, probably no one
will spent too much time on you.

That's worthless as the Bank site must have a valid VPN end point. In
order for there to be a valid VPN connection, there must be two valid
VPN end points. One VPN end point is on your side and the other one is
on the bank's side. The bank side doesn't have VPN for a customer
contact with its network or Website. What the bank has is HTTPS on their
side and your browser goes into a HTTPS session with their Web site and
your browser.

Other than AVG, the anti virus, the rest of the stuff is snake-oil
running on the machine that can be circumvented and defeated, easily,
even the personal FW. Anything that's running with the O/S can be
fooled, circumvented, attacked and defeated.

As long as you have wireless in the mix, you're never going to be secure
enough
as a wireless hacker, with any expertise, can hack the wireless side of
your network and join it with them being all over the top of your
machines wired or wireless.
As long has you are depending upon snake-oil solutions to protect the
machine, then you're never going to be secure enough.
Where you need to start is with the O/S, secure the O/S as much as
possible to attack.
http://labmice.techtarget.com/articles/winxpsecuritychecklis t.htm
You should practice safehex as much as possible.
http://www.claymania.com/safe-hex.html
You should use other tools to help you in the detection and look around
on the machine with the tools from time to time, instead of depending
upon the snake-oil 100%, everything is okey dokey.

Ok, I VPN to an anonymous proxy, which then allows me onto the net, this
hides what I'm doing to my ISP, BUT I'm not doing anything but surf and
online banking, I just dont like people watching what I'm doing. I know the
connection from the anonymous proxy to my Bank is open until the SSL link is
made, but that's ok.

secure for what ?
for the NSA to break in ?
for the BFSA (Burkina Fasso Security Agency) to break in ?
for your neighbor to use your wireless access ?
for you using the computers for MSN chat ?
for your 4-year old daughter to get out on the net ?

Well from what I've read about internet and home network security (over 200
documents), also from the advice of 2 internet security experts, one works
for Telewest broadband and the other sets up bank security both have said
that the my connection is unhackable from the internet side and as I'm using
a completely random 63 character password WPA-PSK (example key:
C>KgRiKC_1ftZ:_]\!1T6`Q]>OX,3|92P.AdCXiZFy!c%bn4mR?SC i3W-BeLOq) mean that
my wireless setup is also uncrackable, as it would take someone sniffing
your connection years to even get near that type of password. Also listened
to www.grc.com security now which he also confirms that a password like the
above is currently uncrackable.
However I know that it's still easy to get viruses,spyware,adware etc by
simply surfing the net, I reduce this by not using Internet Explorer, I also
disable JAVA script on all but sites I believe to be safe.
In regards to Spybot, ad-adware they are recommended by 100s of sites to
help find and remove problems with spyware etc and with my anti virus I am
well covered.
In regards to SSL-Cas, I've not really read enough about this concept so I
won't comment until I've read up on the subject ;)

This is sample of good key. But note that there are others ways to hack you.

The fact that you have even mentioned that *clown* Gibson says it all.
And about your wireless security and your key, why don't you hope over
to alt.internet.wireless where the wireless experts and hackers frequent.

I checked this site, and I think that, beside this one, you should read
something else as well.
For wireless security, this might be good start
http://www.wirelessdefence.org/index.htm
For network security I belive that you can start from here
http://www.governmentsecurity.org/
If somebody have better suggestions just shoot, I'm no expert or hacker,
only a home user.

I see there is only one PC in the house. That is neat, for now you
can put it in the living room, for all to see the screen. So the kids
can't surf to porn sites.
rules of thumb:
0: backup, but not too often. You might overwrite a good backup with a
bad one.
1: Don't give anyone the admin password or access to the FW settings.
2: trust the kids, but verify.
3: Give em all their own id and password
4: nobody can get anywhere unless you say so. not: they all can go
everywhere unless you stop them.
5: no P2P
6: put up something like Netnanny or whatever.
7: have virusscan scan anything that comes in.
8: nobody installs software but you.
9: fear, but don't let it keep you from being happy. there are no VERY
many people that are interested in the contents of your HD, unless you
work for the CIA.
10: backup.

cut&paste don't always work with passwords....
Much better to use a sentence, eg. from your favorite book. As long as

point is, that sometimes discover a system to be corrupt after some
time, in which time you might have made (and overwritten) one or more
backups. So you do not use only two CD/CDRW/tape, to make DAILY
backups.
But you knew that...

Unfortunately, I have to agree with this one. I know how *I* was when

I think you are both saying the same thing essentially.

limiting factors are, amongst others:
1: price,
2: effort to be invested
3: knowledge to be acquired
4: value of data
5: time = money
To ignore these factors is blatantly stupid.

No argument here.

The majority of children who use P2P applications (children being
anybody who is not an adult) are using them to download copyrighted
music. In the US, this practice is in legal limbo at the moment, with
many people being successfully prosecuted, and many not.
There ARE legitimate uses, of course. But I'll wager that far more
people use it for illegal purposes (downloading copyrighted music and
software).
Just check out the files available via Limewire or various Bittorrent
sites. Chock full of files for anybody to download that the copyright
holders have explicitly said they didn't not want available.

We agree on that.

If its coming from the vendor only, I would consider it a trusted
source (to a point). But one has to configure their software to only
d/l from that source. Most P2P software defaults to "find anyone on the
internet that has the same file name available for sharing" which is
clearly dangerous.

on the P2P nets, Bogus data is also indexed by cryptographically
secure checksums
As was found in tests:
people THINK they know a lot about things they know little or nothing
about, and THINK they know little about things they know a lot
about...
