SANS Cheat sheets

The SANS Institute provides some of the best security training in the industry. Many of their classes include the so called "Cheat Sheets" which are short documents packed with useful commands and information for a specific topic. I have linked as many as I am aware of below.

Most of these will require a login to the SANS website. Accounts are free.

An inexpensive method of backing up an SMB to the cloud

First let's get some assumptions out of the way.

  • This is geared toward a relatively well connected organization. What well connected means will greatly depend on the size of the organization but for a relatively small company with maybe a few hundred GB of storage that you want to backup online a business class cable connection will probably meet the bandwidth requirements but DSL or T1 will not. The quality (downtime etc.) is actually much less important than the raw amount of data you can upload.
  • I implemented a solution in an environment I previously worked in and it worked well. Watch the caveats I add throughout the document. They are from experience.
  • This is very much a low tech low cost solution.

Hyper-V Backups using built in Windows tools

At work we have decided to backup some of our Hyper-V servers to disk using the built in Windows 2008 tools and then back that up to tape for rotation. You will find instructions for this process in this article.

Enable VSS on the Hyper-V server

Install Windows Server Backup (WSB) feature

start /w ocsetup "WindowsServe Backup"

Edit the Registry

From command line:

reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\WindowsServerBackup\ApplicationSupport\{66841CD4-6DED-4F4B-8F17-FD23F8DDC3DE}"

How to Suck at Data Backups

This is presented in the same vein as Lenny Zeltser's How to Suck at Information Security.  If you have not read Lenny's article it is highly recommended.
