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...

cyber threatssecurity assessmenthacktivismNASA Mars Rover: Experts Assess Anonymous Hacking Threat
The word has been out for more than a week now that the hacktivist group Anonymous is looking to break into the communication system between NASA and the Mars rover, Curiosity. . The New York security firm Flashpoint Partners reported that it found a message on an Internet Relay Chat (IRC) by a user called "MarsCuriosity," asking for help to hack into the signals NASA uses to communicate with the rover. But within the security community, the rumor has been greeted mostly with yawns, shrugs or a few scornful chuckles. No panic buttons are being pressed. It is being viewed either as a "weak" attempt at trolling, or an effort by law enforcement to lure hackers to fall for a sting.

security threatsuser securitycommunication risksAssessing Skype Security: Implications for Corporate Networks and Users
There's been a lot information -- and misinformation -- available about whether Skype is dangerous to corporate networks and individual users. How dangerous is it? In this article, I'll separate the truth from the myths when it comes to Skype vulnerabilities. . Skype is a peer-to-peer (P2P) application, meaning that users connect to one another directly and not through a central server for communication. Skype initially uses Internet-based servers to authenticate users when they log in and to track their status, but when a "chat" or instant message, "voice call" or "file transfer" is initiated, the parties involved in the communication do so in a P2P direct connection. If one or both of the users are behind a typical corporate Network Address Translation (NAT) firewall, the communication can be relayed through a Supernode because a direct P2P can't be established behind a NAT. In the case of a file transfer, you will see a message indicating your transfer is being relayed. The link for this article located at ComputerWorld is no longer available. . Using Skype as a P2P application presents risks that can jeopardize user security and privacy, necessitating awareness and proactive safety measures from users.

authenticationLinuxdigital signaturesDigital Signatures: Risks and Legal Binding in Linux Systems
Digital signatures were designed to allow secure, confidential communication between two parties. As Wikipedia describes it: "A user may digitally sign messages using his private key, and another user can check that signature (using the public key contained in that user's certificate issued by a certificate authority). This enables two (or more) communicating parties to establish confidentiality, message integrity and user authentication without having to exchange any secret information in advance." . Are digital signatures legally binding? Usually. Check your local statutes. Are they foolproof? Not usually. For years, Prof. Ferenc Leitold of the University of Veszprem has been explaining the dangers of digital signatures to the world at large. This week, he's doing it again at the 15th EICAR Annual Conference in Hamburg, Germany. The link for this article located at Email Battles is no longer available. .

The Internet has radically changed the way we communicate with each other. Email is obviously an extremely valuable and ubiquitous form of communication, but with this technology comes certain pitfalls that should be understood. The path that an email message takes to reach its recipient is a complex and varying one, and while in transit that message may come under the potential scrutiny of numerous different people and organizations. We will attempt to outline the varying paths that an email message may travel, and who some of those different people and organizations might be under whose scrutiny the message may pass. The intention of the document is not to provide a how-to guide; the only specific technique that will be discussed, packet sniffing, is one that anybody with any technical networking knowledge whatsoever is already familiar with - which brings us to an important point. At a round number, there are probably at least a million people in the world with the requisite technical knowledge necessary to intercept Internet-based email. Yes, I said a million. (There are actually probably a lot more than that - maybe several million by now, and more everyday as the populace becomes more networking-literate.) Fortunately, the number of those people who actually have the physical access necessary to intercept email is much smaller, but it is still a very large number.

The ruckus began earlier this week, when the U.S. Postal Service disclosed that it was exploring the e-mail idea.The government would use the e-mail addresses to send driver's license renewal forms, tax documents and other materials that would normally be sent by snail mail. And Americans would visit two mailboxes every day -- the ones outside their homes and the ones inside their computers, said Deputy Postmaster General John M. Nolan.
