data privacy automation Every system admin has lived through the same Monday morning ritual. A queue of forty tickets, half of them password resets, permission errors, or disk space warnings that any experienced technician could resolve in under two minutes. The other half require actual judgment. For years, automation promised that software would eventually sort the two apart on its own. That promise is now being tested in production Linux environments. . Early results are reshaping how IT teams think about tier-1...

Then prevent it by encrypting your e-mail using a program such as PGP (Pretty Good Privacy). PGP was invented in 1991 by Phil Zimmermann as a way to send e-mail so that no one but the intended recipient could read it. It landed him in a world of legal trouble with the feds until they dropped the case after pressure from the computer industry in 1996. However, after Network Associates bought PGP in 1997, development started to drift, and by 2001 work on the software had ground to a halt. Network Associates had effectively shelved the software. Thankfully, the newly funded PGP Corp., based in Palo Alto, Calif., bought the software and released new versions in November 2002 that run on both Windows XP and Mac OS X. First off, don't confuse codes and ciphers. Codes are agreed upon substitutions of words and phrases, like "the baby is in the crib" for "the package has arrived." Ciphers are mathematical formulas that transform messages into gobbledygook. An example of a simple cipher is one that has A=1, B=2, C=3, and so on. So the word "subway" would be represented as 19-21-2-23-1-25. You could make it more complicated by reversing the order of the numbers--so that A=26, B=25, etc.--or you could stick with the original order and multiply the numbers by an arbitrary number, say 7. "Subway" would then be 133-147-14-161-7-175. The link for this article located at PopularMechanics is no longer available. . Safeguard your private messages from prying eyes.

For more than a decade, the United States government classified encryption technology as a weapon. Now that label might actually apply. Security-consulting firm Foundstone said Thursday that e-mail messages encrypted with the Pretty Good Privacy program can be used as digital bullets to attack and take control of a victim's computer. Because of a flaw in the way PGP handles long file names in an encrypted archive, an attacker could "take control of the recipient's computer, elevating his or her privileges on the organization's network," Foundstone said in an advisory.

The intent of this document is to provide the new PGP user with enough information to effectively use PGP. This is just a primer; for more information, check the PGP help file and manual or see the Resources list at the end of this article. I recommend reading these at the first opportunity; cryptographic applications are much safer when used by informed users who understand the basic concepts. The documentation is readable and provides a good introduction to general cryptographic concepts. PGP puts your email or files in a digital envelope that only the intended recipient with a copy of PGP can decipher. Anybody else sees a random-looking sequence of ASCII characters. This process of encryption allows you to open digital envelopes encrypted to your public key. This is the reverse of the decryption process. Many products have "secure" modes that allegedly provide secure information storage and transmission. Unfortunately, most of those products are susceptible to "password cracker" programs readily available at various Internet sites either in freeware form, often aimed at the black-hat community, or as commercial ware marketed to corporate help desks who help their users figure out the passwords they forgot. Law enforcement uses password-crackerprograms, too. If your "secure" product is one that can be cracked this way, it isn't secure. The link for this article located at 8wire is no longer available. .

This article starts out with a nice description of cryptography then goes into how to incorporate PGP for use with Pine. "Encryption is the transformation of data into a form that is (hopefully) impossible to read without the knowledge of a key. Its purpose is to ensure privacy by keeping information hidden from anyone for whom it is not intended. Decryption is the reverse of encryption; it is the transformation of encrypted data back into an intelligible form. Encryption and decryption generally require the use of some secret information, referred as key. Some encryption mechanisms use the same key for both encryption and decryption; others use different keys for the two processes."
