On 29th of September I had Lecture named "Administrators are from Mars, Hackers are from Venus". The lecture was about differences between Administrators and Hackers. I was talking about 10 rules of security, Defense in depth, BoF, DEP and ASLR. Demos showed few "old" things somebody could do if Security is not as it should be, like: BoF, Sniffing encrypted files, how administrator could steal anything including all e-mails. Also I showed how an USB stick could be really scary thing because all you have to do is to stick it and all your data could be compromised. I also showed key logger and what it could do to your security.

Download demo 3: (I read your e-mail) - no sound

If you want to protect your Exchange 2007 with DPM, please
read this article:
If you are lucky everything will work, if not, you will have to play around with it.
Read this if everything else failed.I hope this article will help you install DPM 64 bit agent on your Windows server 2008 or Vista computer.
The thing is that I had no problem with DPM client installation until yesterday, when I had to install it on Windows Server 2008 with Hyper-V role and Microsoft Exchange server 2007.
I try to push installation of DPM client from DPM server and the installation failed.
What you have to do is:
1. Install Exchange server management tools on DPM server.
If your DPM server is 32 bit
download 32 bit Management tools for Exchange 2007The main point is that you must install same version of tools as on your Exchange server.
Version 8.1 build 240.6 is Exchange 2007 with SP1
2. Copy eseutil.exe and ese.dll to DPM/bin folder,
or even better create hard link to original files from DMP/BIN directory.
How?
Read the whole articleFsutil hardlink create “c:\program files\microsoft\dpm\bin\eseutil.exe” “c:\program files\microsoft\Exchange\bin\eseutil.exe”
This command will fail if you already copied those files in DPM/BIN directory. If this is the case, just delete them (in DPM/BIN directory) and run command again
3. Install DPM Feature pak
32-bit version64-bit version
4. Now go to your exchange server 2007 and try to install DPM agent manually.
How?
- Run DPM agent installation file from C:\Program Files\Microsoft DPM\DPM\Agents\RA\2.0.5820.0\amd64
DPMAgentInstaller_AMD64.exe nameOfDPMServer
- Run DPM upgrade installation from C:\Program Files\Microsoft DPM\DPM\Agents\RA\2.0.8107.0\amd64\1033
DPMProtectionAgent_KB949779.msp
Of course those paths are on DPM server you could share those directories or copy the files to your Exchange server 2007
If installation fails stop Windows Firewall service and try again
This is the part where my installation worked. :-)
Interesting part is that I had to stop Windows firewall service - disabling it trough Firewall GUI was not enough!
5. If you installed DPM Agent manually as explained in previous step, you should add it to DPM console using DPM Management Shell
- type Attach-ProductionServer.ps1 and then pass the following informations:
DPM server name
Protected server name
Username (admin)
Password
Domain

I'm "sick and tired"on searching web for information if some CPU support or does not support virtualization
Intel web site is unsearchable (at least I have problems with it :-) )
An now after 2th time I have to deal with CPU that reseller said it supports virtualization (and it did not) I decide to compile a list of supported CPUs for future references.
Searching the web for answers did help a little, but the lists I found are not completed (neither is mine, but it has more info :-)).
So before i give you a list pleas red the following:
1. CPU MUST be 64 bit
2. CPU MUST have Intel VT technology support
3. CPU MUST have Execute disable bit support
4. Motherboard MUST have support for Intel VT
5. Motherboard MUST have support for Execute disable bit
Here is a list of CPUs that does not support virtualization (according to Intel):
Quad Core CPUs:Q8200 - this is the only quad core CPU I found on Intel site which does not support Intel VT (until then I was thinking that all quad core CPUs supports Intel VT technology)
Intel Core 2 Duo CPUs:E8190
E7300
E7200
E4700
E4600
E4500
E4400
E4300
T52x0
T5300
T54x0
T5500
Intel Pentium Dual-Core Processor
E5200
E2220
E2180
E2160
E2140
Intel Pentium D CPUs945

E450
Intel Celeron Dual CoreAll (at the time of writing - according to Intel)
E1200
Intel Core Duo
T2300E
T2x50
Intel Pentium 4 single core that SUPPORT virtualization:
672
662If you found some of this CPUs to have Intel VT support, please comment it.
If you found some other CPU not on this list that does not support Intel VT, please write a comment
I strongly advise you to check with manufacturer for every CPU you are planning to purchase, and be careful, for instance: T7200 does support virtualization, but E7200 does not
