FCC to make ruling on “White Space” usage.

2010-09-21/0 Comments/in General Security/by SecurityOrb_Staff

On September 23rd the FCC will vote on a new set of rules that will finally allow their planned “super WiFi” to become reality.

In 2009 the FCC voted to open up the vast amounts of “white space” frequencies that lie between television broadcast channels.

FCC to make ruling on “White Space” usage.

We covered this topic with Alton Drew of The Alton Drew Group on The Tech Talk Show. The discussion pertain to how “White Space” will aid in bridging the digital divide. Of course there are security implications SecurityOrb.com will cover on this topic.

Adam Carpenter of the Fort Worth Gadgets Examiner for examiner.com wrote an interesting article.

On September 23rd the FCC will vote on a new set of rules that will finally allow their planned “super WiFi” to become reality.

In 2009 the FCC voted to open up the vast amounts of “white space” frequencies that lie between television broadcast channels. The move was the first time since 1985 that the FCC has opened up a new set of unliscenced frequencies. The frequencies that were opened in 1985 are the very same ones that are currently used for current WiFi internet, many remote controls, baby monitors, cordless phones, etc. A vast amount of innovation began when the frequencies were opened then, and as FCC Chairman Julius Genachowski said “We’re hoping history will repeat itself.”

The EnCase Evidence File Format

2010-09-20/0 Comments/in Computer Forensics/by admin

The EnCase evidence file can also be referred to as a forensic image file. The concept of an image file is where the entire drive contents of a target media is copied to a file and checksum values are calculated to verify the integrity (useful in court cases) of the image file (often referred to as a “hash value”). Forensic images are acquired with the use of software tools such as the UNIX “dd’ and FTK Imager as well as hardware were cloning devices such as the Solo Masster and Logicube’s MD5 have added forensic functionality.

One major difference between the above mentioned techniques to acquire image files and the EnCase image files is the “bag-and-tag” concept. The UNIX “dd” and many of the hardware cloning devices only provide the bit-for-bit information during acquisition. EnCase on the other hand provides the bit-for-bit data as well as additional data such as case information; data block integrity and file integrity to name a few. These functions are built into the EnCase imaging process for interoperability and ease of use. If the same function were to be implemented using the UNIX “dd” or the hardware options, this process would require many different tools and multiple steps to obtain the same results.
