How
to secure Windows2000 / XP
IMPORTANT
INFORMATION REGARDING WINDOWSXP SP2 Some
security softwares have had problems with Service
Pack 2, like for example ZoneAlarm and some antivirus
software. Also, there has been other issues regarding
the SP2, I have personally found out that after
installing it my computer stops working properly,
I have not yet managed to solve the situation. Also,
the SP2 has some changes regarding the settings
of Internet Explorer, Windows ICF and other issues,
so this page is not updated to meet SP2 details
for now. My suggestion regarding SP2 is, that you
should backup and try it out. If it works, fine,
Microsoft has fixed some major security issues with
it so you likely safe enought for now on default
install on SP2 if you follow its security center
guides. If you cannot install SP2 or get it working,
then restore the old WindowsXP and use the settings
and tips in this page as it is. Try later to install
SP2 when Microsoft either fixes its bugs or we can
discover some way to counter them.
These
settings can be used with both Windows 2000 and
WindowsXP to *really* secure the system and also
boost up its performance. Depending upon your version
and whether it is Win2k or XP, you might notice
that some of the features/options arent there. Just
skip and move on until you hit something that IS
on YOUR Windows2k/XP. The "best" option
of all is to have WindowsXP professional, since
the screenshots are from WindowsXP professional.
However, please notice that you can access some
of the features in WindowsXP professional even if
you are installing home edition, by booting into
"Safe Mode" some time.
WindowsXP
offers pretty good security features, but only if
you know how to use them. By default, WindowsXP is
clumsy and has many possible security holes due to
its poor default settings. If you use WindowsXP pro,
you can really make your computer your fortress against
almost any invader. The build-in EFS (Encrypting File
System with NTFS), strong authentication methods,
firewall, etc. give you good tools for it. Home edition
does not have all these features but you can always
implement your own according to these guidelines.
These principles are designed for ONLY single-user
"home" computers (standalone), NOT computers
in, lets say, corporate networks! On standalone computers
you can and should fill all holes possible but in
corporate enviroment, the whole point is to allow
computers to be used via corporate networks or intranet.
You can still take suggestions and clues here and
implement them properly if you are installing or using
Windows2k/XP in corporate enviroment or are using
multiple user accounts.
PLEASE
READ THIS CAREFULLY! Even
if you are not planning on securing WindowsXP of yours,
please read
this and implement it. Even if you dont care about
computer security or think this is not important to
do, read
and implement it anyway. Trust me on this
one. If you think you dont know how to do it or
are not sure on whether or not to do it, do
it anyway. Its very easy and implementing just
these 7 simple
things will GREATLY improve your security. Its
just 7 easy steps to make! You can ofcourse also print
this page
to help you look at it better and implement it.
If
you want to download and print this page, you can
do it easily by downloading/printing this
.rtf document. It has everything that is sayed
in this page. I recommend that if you are about to
install Windows 2000 / XP, download and print it so
you can easily use it to secure your computer offline.
Important
information about Windows 2000 and Encrypting File
System insecurity
There is very little reason to use EFS on Win2k standalone
installation since it does not offer real protection
in Windows2k. It is possible to reset the administrators
passphrase (even with Syskey enabled and stored in
floppy) and login as admin. This can be done by simply
booting the computer in other operating system and
deleting the SAM file and manipulating the registry
so that Windows does not want to have Syskey during
startup. If Syskey is not present, resetting the administrators
passphrase is much easier. Administrator can do many
things and is the default recovery agent of EFS. In
any case, once you have logged in as admin, you can
decrypt all data encrypted with EFS in that computer.
In
theory, it *is* possible in standalone Windows 2000
to have secure EFS, but it is very, very, very complicated
to archive. In theory, by exporting the administrators
recovery certificate or designating some other recovery
agent AND implementing Syskey to passphrase or floppy,
it *might* be possible to prevent anyone from reading
EFS encrypted files. It is always possible to login
as administrator, but if the administrator does not
have the recovery keys, he cant decrypt EFS files...
And since the Syskey *prevents* tampering the other
accounts, it is in *theory* safe (if hacker deletes
SAM file, then other accounts loose their vital piece
of information and cant be used and therefore they
cant get access to private key). But in practise...well...who
really knows? I STRONGLY
recommend not to use EFS in Windows 2000 unless
the computer is a part of domain and the settings/security
policies are good and the actual computer where the
certificates are stored is in safe place so nobody
can get a physical access to it and Syskey for each
computer is stored in passphrase or in floppy format.
Use PGPdisk instead and you dont have to worry about
these kinds of issues with Windows 2000!
Please
remember!
As
sayed earlier, these settings work like dream for me
and most 2k / XP users too, but not with all of them.
The best option would be to either make and "image"
of your C-drive or write down your original settings
before you start implementing these settings. The problems
that might occur are mostly related to network connections
/ internet access. You can also troubleshoot the problems
using the Windows Help and Support while going throught
the settings to see what needs perhaps to be enabled.
And if the worst happens...And you just cant revert
the changes you made, run "repair install"
using your Win2k/XP cdrom. It will keep all the programs
etc. but restore regular settings. Remember to update
and patch your software after this "repair install".
When
you do some alterations to settings, make sure you exit
that window by pressing OK or YES keys. If you simply
close the window clicking from the X in the corner of
it or press CANCEL, the alterations you just made will
NOT become affective!
Before
installing Windows 2000 / XP
-> Physically disconnect from the net!
- -> Do NOT plug the network cable/internet connection!
->
Backup all your personal files and documents to different
HDD or partition
--> Optionally back up to CDRW or external HDD
During
installation of Windows 2000 / XP
-> Delete old system partition(s), install from "fresh"!
--> Its a good idea to create atleast two partitions,
one for the system (you need atleast 5 Gb for this one,
but 10-20 Gb is better) and second for your own files
and images from first partition (rest of the HDD space,
but atleast double the amount of what is the size of
first partition, so atleast 10, but 20-40 Gb is better).
Ofcourse, if you have backed up your data to some other
partition than C:, then do NOT remove or format that
partition or your backups will be lost!
---> Format partitions to NTFS.
->
Create one account for yourself (besides the default
"administrator account" there already is).
This account does not have password by default.
->
Use good passphrases, atleast 14 marks long, containing
both letters, numbers and special marks (like !"#¤%&/().).
To be ultra-secure, use over 28 marks long Administrator
passphrases.
--> Never use the same passphrase in two places/systems
After
installation is done
-> When logging in first time when "Welcome"
screen appears
--> Press ctrl+alt+del (couple times in row perhaps)
---> Login as Administrator and with administrator
passphrase

you can easily change one of the accounts here from
"administrators group" to "user".
--> Enable: Users must enter a user name and password

on those folders so that they can save games etc. Same
goes if you store other files in those partitions, like
music, documents etc. that other people want to not
only access, but also save and edit. Then you should
give "Authenticated Users" full permissions
on those folders. The main thing is, that your personal
folders (C:\documents and settings\userX\) are safe
from other peoples tampering and so are important system
folders (C:\windows\).
->
To encrypt (EFS) the content of directories and prevent
all other users (including administrators) from reading
the content of files inside (only in XP pro version)
the directory (notice: they can still see the file names
and alter folder settings)
-> Only use this for YOUR personal directories (like
to folders where you keep personal documents etc.),
do not use on system, program, etc. directories!
--> Right click on your mouse to the directory you
wish to encrypt
---> Properties
----> General
-----> Advanced
------> Enable: Encrypt the contents to secure data
(notice: If you are logged in as administrator, this
will encrypt the data for administrator account only.
To encrypt data for your USER account, please secure
you WindowsXP installation, login as user and then start
encrypting your folders)
(Optionally)
Export your EFS certificate
-> Make sure you have encrypted some directory with
the user that you wish to export the EFS certificate
from (otherwise you dont have EFS certificate which
to export)
-> Run: MMC
--> File
---> Add/Remove Snap-in
----> Add
-----> Select: Certificates
------> Add
-------> Select: My user account
--------> Finish/close/OK
--> Certificates - Current User
---> Personal
----> Certificates
-----> Select your certificate from the right window
------> Right click with your mouse
-------> All tasks - Export
--------> Next
---------> Select: Yes, export the private
----------> Next
-----------> Write a passphrase to protect the certificate
and remember it!
------------> Choose where and under what name to
export it
-------------> Next, etc. etc.
Reboot
your computer
-> If/When "Welcome" screen appears
--> Press ctrl+alt+del (couple times in row perhaps)
---> Login as (WHATEVER NAME YOU RENAMED THE ADMINISTRATOR
ACCOUNT AS) and with administrator passphrase
Now
you can physically connect to internet!
-> Plug in the network cable etc.
--> Set whatever settings needed to make it possible
for you to connect to internet.
Update
Windows
-> Go to http://windowsupdate.microsoft.com
--> Download ALL updates available
---> Reboot when asked to administrator account again
----> Return to this site to download more and more
and more patches
-----> Continue to download/install patches, rebooting
and returning to this page until you have downloaded
ALL patches and cannot download any more patches.
-> Remember to come back to see new patches hopefully
every week but atleast once a month! We have set automatic
Windowsupdate, but I STILL insist that you recheck for
ANY new updates every once and while. Just to be sure.
Updating your Windows, Windows Media Player, Internet
Explorer, Outlook Express etc. is REALLY THAT IMPORTANT!
Download,
install and use free software to secure your computer
-> Remember to login as administrator before installing
anything to your computer!
-> For more info, go to http://markusjansson.net/software.html
And
finally...
-> Go throught this list AGAIN, since so might have
missed something, or some updates/patches might have
changed some settings, for example downloading Windows
Messenger update automatically changes your ICF setting
(!!!), opening few ports on your system!
-> When you are done installing, updating and securing
your Windows XP, login as USER with the passphrase you
resetted it to previously. Only use ADMINISTRATOR account/permissions
when you REALLY need to install/update/modify some settings.
Logging in as administrator permissions is severe security
risk and it should be avoided at all costs.
--> Remember to change the password in all new account
when you login for the first time. By default, new accounts
have NO password set. Press Ctrl+Alt+Del and Change
Password to change your password.
