security advisory vulnerability
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. . Because GNOME is the default desktop environment on several major Linux...

Security Vulnerabilities security advisory moderate
security advisory moderate For organizations that run a self-hosted Git platform, it’s no longer just about hosting static code repositories. Today, Git servers are responsible for deployment pipelines, API tokens, SSH keys, package repositories, and the automation scripts that push code directly. Confirm that the upgrade addresses known vulnerabilities but also provides production environments. . That makes them trusted systems within the development environment and attractive targets for attackers looking to move...

Server Securitydata privacy automation
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...

security advisory social engineering Business Email Compromise used to be a numbers game — mass-blasted emails, broken English, an obvious "URGENT WIRE TRANSFER" subject line. That era is over. Generative AI has turned BEC into a tailored, low-noise operation that mimics writing style, voice, and even video presence. This piece looks at what's actually changed under the hood, what defenders are testing in response, and why so many organizations are still structurally unprepared for it. .

Quantum cryptography goes a step further than electronic cryptography through its employment of a stream of photons, the quantum properties of which determine the key. The fun part is that if an intruder observes or intercepts the transmission, those properties get changed -- an unavoidable principle of quantum mechanics -- meaning the sender and receiver can tell if anyone is eavesdropping.

After two years of rousing debate, the body responsible for the Wi-Fi standard is finally putting the finishing touches on its new security standard, IEEE 802.11i. Although this standard's Robust Security Network feature will deliver the level of security the wireless world is clamoring for, don't be fooled: Your wireless network won't be secure until your transition to RSN is complete. RSN defines two security methodologies--one for legacy hardware based on RC4 and one for new hardware based on AES. The standard also provides the flexibility to add new methodologies if the need arises. RSN uses the IEEE 802.1x port-authentication standard to authenticate wireless devices to the network and to provide the dynamic keys it requires. The task group does not specify any authentication method over 802.1x; it just defines the features such a method must provide. The idea here is to "future-proof" the RSN authentication process.

This article is the fourth in a series that is designed to help readers to assess the risk that their Internet-connected systems are exposed to. In the first installment, we established the reasons for doing a technical risk assessment. In the second article, we started to discuss the methodology that we follow in performing this kind of assessment. The third part discussed methodology in more detail, focussing on visibility and vulnerability scanning. This installment will discuss a relatively unexplored aspect of Internet security, custom Web applications. Of all the possible services on the Internet DNS, e-mail and the World Wide Web are by far the most pervasive. (In fact, in July 2002, the monthly Netcraft Web site survey reported that 37,235,470 active Web servers were connected to the Internet.) Of these, Web services are the most complex and the most frequently abused. Originally a simple text-based information service, the Web has developed into a highly functional interactive application development platform that is being used for almost every possible application on both the Internet and Intranet. Major vendors have recognized the power of the Web and have made significant investments in Web development platforms. These include Sun (Java), Microsoft (Active Server Pages, Site Server and Commerce Server), the open source community (PHP) and others (ColdFusion). Such platforms make it very easy for standard administrators to develop complex applications. A simple wave of the Web development wand and suddenly everybody's a programmer, even me! Web applications are often developed by under-qualified, inexperienced developers. Unknowingly many programmers make errors that provide potential intruders with precisely the vector they need to penetrate theprivate network. As these applications are built on standard platforms, they tend to look similar, and tend to have similar security weaknesses.
