Security Modes of Operation
Oct 10th
There are various modes of security operations depending of the information you are protecting and it’s classification. Here is a review of some of the modes of operation.
History of CRYPTOGRAPHY
Oct 9th
Cryptography can be defined as the conversion of data into a scrambled code that can be deciphered and sent across a public or private network. Cryptography is far more than helping keep integrity of the communications. It has evolved into a tool used in communications in a daily bases. Here is basic introduction to Cryptography.
Security Architecture & Design / Security Access Control Models
Oct 9th
Security Architecture include models to follow to design a security oriented network infrastructure. They will depend on the need of security classification. Each model will be focus on a specific area of the security tria Confidentiality, Integrity and Availability.

Applications and Systems Development Security
This domain examines the security components within operating
systems and applications and how to best develop and measure their
effectiveness. This domain looks at software life cycles, change control,
and application security. Some of the other topics covered include:
Netbooks Do we Really need them?
Aug 4th
Do not be confused; “net books” are a fashion statement, and that is about it. Commerce is forcing users to go into cloud computing, at the end people do not realize that they spend about the same amount money at the long run.
Example:
This is no promotion for Dell
You buy a netbook for about $300 dollars and comes with, no optical bay, XP Home (useless) or Ubuntu ( ….. oh.. well ), a little hard drive, 1 USB port and like 1 Gig of RAM. If you are an email reader and web search person then great that is a PC for you. But if you are a WEB 2.0 user (Face Book, Twitter, Flickr, and so on), then the computer is completely helpless. Afterwards they force you to buy an external hard drive which runs from $60 to $100 depending on capacity and a USB HUB because all external peripherals are USB. So lets see, a $300 laptop, $100 external hard drive, $40 USB Hub, and $60 external optical bay (more or less) it is looking like $500 dollars. WoW that sound like the price of a real labtop with built in USB hub, built in optical drive, minimum 300GB hard drive.
Yes, I know it sounds cranky, and yes some “netbooks” have optical bays, it is just an example and to me a reality.
If you look at the trend computing is going back a couple of steps, to time of Dumb terminals and mainframes. A netbook is design to have a network infrastructure supporting all it’s needs. That is the reason they are low in resources. To really make it work you need a Home server or a File server hook to it. You will need a good infrastructure to move things around and always have them on the network.
Manufactures do whatever consumers support, if people go buy netbooks they will make more netbooks. I am not saying do not buy one, I am saying know what your buying before you do. I personally will own a net PC, just because I think it is an ultimate hacking machine. Small, you can hide them, penetrate into systems and do what ever you want because of portability. I can plug in a 16GB pen drive and have BT4, Server 2003, Server 2008, Red Had and Knoppix all virtualized. But that is not a regular use I would say.
Technology advancements are great; I think people should be aware of what they are buying before they do.
