Getting Started with Windows VDI by Andrew Fryer

Wed, 2014-09-10 06:55
Virtual desktop infrastructure (VDI) is the practice of hosting a desktop operating system within a virtual machine (VM) running on a centralized server. VDI is a variation on the client/server computing model, sometimes referred to as server-based computing.
VDI is the new technology that gives lots of benefits.
• Efficient use of CPU and memory resources
• Reduced desktop downtime and increased availability
• Patches and upgrades performed in data center
• New users can be up and running quickly
• Data and applications reside in secure data centers
• Centralized management reduces operational expenses
Additional, VDI can be deployed with Microsoft Windows and suggest to learn What’s New in VDI for Windows Server 2012 R2 and 8.1
Anyway, I explained much more before starting to mention a book that was written by Andrew FryerGetting Started with Windows VDI - This book guides readers to build VDI by using Windows Server 2012 R2 and 8.1 quickly and easy to follow each chapter.

What Readers Will Learn:
  • Explore the various server roles and features that provide Microsoft's VDI solution
  • Virtualize desktops and the other infrastructure servers required for VDI using server virtualization in Windows Server Hyper-V
  • Build high availability clusters for VDI with techniques such as failover clustering and load balancing
  • Provide secure VDI to remote users over the Internet
  • Use Microsoft's Deployment Toolkit and Windows Server Update Services to automate the creation and maintenance of virtual desktops
  • Carry out performance tuning and monitoring
  • Understand the complexities of VDI licensing irrespective of the VDI solution you have opted for
  • Deploy PowerShell to automate all of the above techniques

Penetration Testing A Hands-On Introduction to Hacking

Sun, 2014-06-29 04:47
Assessing overall security on a new system before it goes on-line is also a good idea. It's useful to find holes before somebody else does, verify secure configurations and testing.  Penetration Testing is the process of attempting to gain access to resources without knowledge of credentials and find security weaknesses (Interesting paper).
Penetration Testing A Hands-On Introduction to Hacking By Georgia Weidman. A book was written about the basic of Penetration testing. It gave concepts, ideas, and techniques in 5 parts: The Basics, Assessments, Attacks, Exploit Development and Mobile Hacking.
  • Crack passwords and wireless network keys with brute-forcing and wordlists
  • Test web applications for vulnerabilities
  • Use the Metasploit Framework to launch exploits and write your own Metasploit modules
  • Automate social-engineering attacks
  • Bypass antivirus software
  • Turn access to one machine into total control of the enterprise in the post exploitation phase
First of all, Readers must set up their Virtual lab by using Kali linux. A book gave lots of ideas, examples how to use Tools for Penetration Testing. It's very good book for some people who are new with Penetration Testing. It might not cover everything about Penetration Testing, or gave the deeply knowledge. However, it helps readers are able to understand in Penetration testing easily and practice in examples.

start python learning with "Introduction to Python"

Sun, 2014-05-04 00:53
Python is programming language, that supports object-oriented, imperative and functional programming. The key is its simplicity, easy language to learn and easy moving code from development to production more quickly. It's power tool to use with Big Data. So, I believe it's a good time to learn about Python programming language.
You can find many resources about it on the Internet. I started to learn about Python by watching "Introduction to Python" By Jessica McKellar. It's good  learning video help to start with Python.
It gives a lot of examples for Python and easy to learn. If you would like to start Python programming by your owner, starting with this and learn:
- Set up a development environment with Python and a text editor
- Explore basic data types such as integers, strings, lists, and dictionaries
- Learn how looping lets you do lots of work with a little bit of code
- Gain access to more functionality in Python with modules
- Practice reading, writing, and running your first Python programs
- Navigate the command line for writing larger programs
- Write your own functions for encapsulating useful work
- Use classes to group, name, and reuse functions and variables
- Practice what you’ve learned with the state capitals quizzer and Scrabble cheater projects
You are supposed to learn and get what are necessary for Python beginning by video course.
