security advisory vulnerability GNOME is officially shortening its standard vulnerability disclosure window from 90 days to 30 days, a change that impacts upstream maintainers, downstream Linux distributions, and system administrators in how they handle software vulnerabilities. The policy shift, announced by long-time security coordinator Michael Catanzaro , addresses modern software patching realities and a growing influx of automated submissions. .

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...

At the 2010 Hacker Halted Conference in Miami on October 13, 2010, SECNAP Network Security will demonstrate the ease with which cyber sniffers, eavesdroppers and hackers can intercept email messages, despite widespread user trust that email messages are private and secure.. Email encryption techniques, such as PGP, TLS and SSL, have limited effectiveness in securing email messages as they travel from point A to point B. Public-key encryption solutions have numerous weaknesses, and suffer from the absence of a universal key repository. Some symmetric encryption solutions have vulnerabilities as well. "To date, no solution on the market could guarantee complete, end-to-end encryption of email content, headers, attachments and other identifiers," said SECNAP Network Security chief Michael Scheidell.

data protectionencryption techniquesdisk encryptionFull Disk Encryption Techniques For Enhanced Data Protection
Today, full-system encryption in software is feasible and practical. Here's how to get up and running using solutions from PGP, McAfee, Sophos, and open-source options TrueCrypt and DiskCryptor. There was a time, not all that long ago, when a fully-encrypted system disk was something only for people with money to burn. . You bought a special disk controller which performed hardware-based encryption, and then trusted the hardware vendor to make sure everything was implemented properly -- e.g., that they were using a good algorithm, that the key size for the encryption wasn't laughably short, and so on. Today, full-system encryption in software is both feasible and practical -- although how practical will depend on the workload involved. But it's not a security silver bullet, much as it might seem to be from the outside. It can, and does, add a layer of protection that greatly reduces the risk of data compromise in the event hardware is lost or stolen. But that protection depends entirely on how it's implemented, and whether or not the user's been educated in the way an encrypted system works.

If you travel across national borders, it's time to customs-proof your laptop. Customs officials have been stepping up electronic searches of laptops at the border, where travelers enjoy little privacy and have no legal grounds to object. Laptops and other electronic devices can be seized without reason, their contents copied, and the hardware returned hours or even weeks later. Now that we're jumped ahead an hour and are seeing less snow (at least here out east), we can start moving about the world again with our trusty laptops - be sure to give a quick once over of the above article!

data securitydata encryptionencryption techniquesHarnessing Quantum Cryptography for Secure Data Transmission
With security on the Internet, there's always some nagging doubt. Can you ever be absolutely certain, for example, that the e-mail you're sending with some confidential business information attached isn't going to be intercepted and read as it travels the digital highways and byways? Using the Internet for anything sensitive requires some faith that everything in place to ensure the security of the information you're working with. But uncertainty can be useful. For years, security researchers have been experimenting with harnessing one of the underlying rules of quantum physics, known as the Uncertainty Principle, which states that at the quantum level, where objects are infinitely small, it's impossible to measure electrons and photons and other similarly tiny particles without affecting them. How does quantum physics apply to the world of security? The idea is to harness this inherent uncertainty to create a data-encryption scheme that's essentially unbreakable. It's called quantum cryptography, and already some governments and private companies are using it to build absolutely secure lines for data and voice communications.
