Hacker -- SSL 3.0 Poodle vulnterability and how disable SSL 3.0 on Windows Server

POODLE vulnerability is an attack in SSL 3.0 and it is a defect of the protocol, not an implementation issue. For more information read the article released by Google.

Each implementation SSL 3.0 has this problem. Security experts recommend system administrators to disable SSL 3.0 and Use TLS 1.1 servers or 1.2.


To test whether the network server using SSL v3, go to Toolbox GeoTrust SSL and type the URL of the server to monitor and click on Check.

https://ssltools.geotrust.com/checker/views/certCheck.jsp 

If SSLv3 is enabled your server is at risk 

  1. In this case, to disable SSLv3 you need to execute as Administrator regedit. 
  2. HKEY_LOCAL_MACHINE\SYSTEM\
    CurrentControlSet\Control\SecurityProviders\Schannel\Protocols\
    
  3. Right click button on the Protocols item and select New> Key --> SSL 3.0 folder.
  4. Right click button on the item SSL 3.0 folder and create a new key named Client.
  5. Again, make a click with the right mouse button on the item SSL 3.0 and create the strong name key Server.
  6. Make click with the right mouse button on the client and select New> DWORD (32-bit) Value.
  7. Give the name of the DWORD DisabledByDefault. Make a double click on DWORD and enter 1 as Value data and click OK to confirm.
     
  8. Repeat the same procedure for the Server entry and assign Enabled as the name of the DWORD. Leave Value Date with the default value set to 0.
  9. Restart Server 
Alternatively you can create a .reg file coping and paste following text and add it to your system register.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Client]
"DisabledByDefault"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Server]
"Enabled"=dword:00000000
 

For the moment, there are no available patch as the problem is a defect and not due to the implementation of the Protocol.

Program - How to backup exact copies of USB flash drives




Use ImageUSB to write an image to multiple USB Flash Drives! Designed for use with OSForensics.

ImageUSB is a free utility which lets you write an image concurrently to multiple USB Flash Drives. Capable of creating exact bit-level copies of USB Flash Drive (UFDs), ImageUSB is an extremely effective tool for the mass duplication of UFDs. ImageUSB also supports writing of an ISO file byte by byte directly to an USB drive (*). ImageUSB can also be used to install OSFClone to a USB Drive for use with PassMark OSForensics™.

With ImageUSB from PassMark Software, you can easily create exact image copies of any USB flash drives and store them on your PC.

Plug in the USB drive you want to back up and click on ‘Refresh Drives’. You should see your USB flash drive, referred to as a UFD by the program, at the top of the application window. Select it and then ‘Create from UFD’ below. For security, you can also select Post Image Verification to ensure that your backup matches the original UFD. This will create an image file of your UFD with the extension .bin.
You can now copy this image on to another UFD, or multiple UFDs simultaneously by selecting them all before clicking the Write to UFD button. In our example, we have plugged in four UFDs at the same time for duplication.

Unlike other USB duplication tools, ImageUSB can preserve all unused and slack space during the cloning process, including the Master Boot Record (MBR). ImageUSB can perform flawless mass duplications of all UFD images, including bootable UFDs.

Programs - Some LAN inventory tools

Here are some useful lan inventory tools:

1. I used this tool: http://ondemand.manageengine.com/service-desk/

It was flexible and offered both a helpdesk trouble ticket solution as well as the hardware/software inventory and is hosted, so, it didn't require any on-site installation except for one agent to funnel the inventory results through. 


2. We use LanSweeper. Highly customizable to the point of adding nearly any tool to the CMD bar for devices. Fast and efficient. You can use the FREE version or buy as the cost is low. No agents to install. After initial run, you'll want to start telling LanSweeper what certain devices are. I really like the grouping options and the ability to add any tools you can possibly run on a device remotely.  

3.  Spiceworks http://www.spiceworks.com/.

Server - AD user account lock out problem

If you have more than an account that usually lockout to better investigate this kind of problem you can have this information from the Security Log of your Domain Controller. If you have more than 1 DC, you can check each of your DC for Event ID 4740 (it's an information). In this Event Log, you will have the computer name of the logon request.

If you have a lot of DC, there is tool (Account Lockout and Management Tools) you can use --> http://www.microsoft.com/en-ca/download/details.aspx?id=18465

Then, locally on the computer, look for aomething that could run under under user account

Veeam - Veeam Endpoint Backup Free

Today at VeeamOn conference in Las Vegas Veeam has announced a new FREE tool: Veeam Endpoint Backup Free. With this new free tool you can finally backup your physical Windows hosts. Desktops laptops and servers starting from Windows 7 and Windows...

Original announcement from VEEAM

We've been very clear about our vision for the Modern Data Center recently: it has key attributes such as being highly virtualized, having modern storage and is ready for a cloud strategy. But what about systems that have data on them that aren't part of the data center? What about endpoints?  Most companies use PCs or laptops for their end users and those devices have data on it that may need to be protected.

To help address this need, we just announced a new product via a press release at VeeamON 2014 today. We are happy to introduce Veeam Endpoint Backup FREE!

Veeam Endpoint Backup FREE is Veeam's new backup solution for Windows-based computers (desktops & laptops) running Windows 7 and higher as well as Windows Server 2008 and higher. It is a standalone product and is not part of Veeam Backup & Replication nor the Veeam Availability Suite. This is clearly big news, and you may have a number of questions on what this new product is. Here are some FAQ on this announcement:

What is it?

Veeam Endpoint Backup FREE is a product that allows you to backup your Windows-based computers to an internal or external hard drive, a NAS share or a Veeam Backup Repository. It writes the backups in VBK format, which is the same format as Veeam Backup & Replication. With this product, you will be able to protect files, volumes or your entire computer based on your own schedule or at logon or logoff. The figure below shows the backup job control panel and it's activity:

Windows-based computers' backup job control panel and it's activity
The possibilities to recover range from simple files (overwrite or keep the original files), volume restore or a bare metal recovery.

Backup Browser and its possibilities to recover range from simple files, volume restore or bare metal recovery.
Additionally, Veeam Endpoint Backup FREE will have great features such as pausing the backup when the system is busy (automatically, with the optional Backup I/O Control selected), automatic update notifications, auto-recognition of the external hard drive that has your backups stored and much more.
When creating recovery boot media, you will also automatically receive additional tools such as checking the system memory, fix startup sequences and a unique administrator password reset.
And all of this, as the name states, will be available for free!

When will it be available?

The first beta of Veeam Endpoint Backup FREE will be released in November and the GA (generally available) date is targeted early 2015. You can sign up for the beta here: http://go.veeam.com/endpoint.

Does free mean no support?

Veeam Endpoint Backup FREE will be supported through Veeam's free product support policy. This means that Veeam will attempt to provide support for users of Veeam Endpoint Backup FREE but does not provide response goals or response guarantees for this service.

Welcome Veeam Endpoint Backup FREE!

Veeam Endpoint Backup FREE will solve the IT Pro's challenges to protect their endpoints at NO cost. And because of this, they will lower their risk of data loss. What do you think of this news? Share your comments below.

2012 Server - Wbadmin System state backup

There is a very easily way to backup system state Windows 2012 Server and it's the following (using windows server backup)
  1. Execute cmd with administrative rights
  2. wbadmin start systemstatebackup -backuptarget:externalhd
  3. I recommend instead you use wbadmin start backup -allCritical for AD restore See link)
 In this way you would have relative backup on external drive
