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 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...

For IT security practitioners, hearing about defense in depth can conjure up images of clutter. Here to cut through that clutter, point out the shortcomings and offer a better way is CSO columnist Ariel Silverstone. . Defense in Depth is arguably the most time-tested principle in security and applies to the physical security as well as online.

data protectionencryptionsecurity strategyUnderstanding Laptop Encryption: Strategies for Enhanced Security
To maximize the effectiveness of encryption in providing effective security assurance solutions, organizations must deploy it as part of a defense-in-depth security stance. Like any technology, encryption is plagued with pitfalls, mistakes, and traps that could easily provide an organization with a false sense of confidence in its security, while still allowing attackers to easily compromise the organization. The general mathematics behind an encryption algorithm is fairly straightforward. At first glance, writing algorithms seems to be very easy to do. In reality, writing secure algorithms is extremely difficult. The details of how the algorithm is assembled play an important role in its effectiveness.

intrusion detectionnetwork protectionsecurity strategiesCloud Security: Essential Defense Strategies for Robust Protection
One of the basic philosophies of security is defense in depth: overlapping systems designed to provide security even if one of them fails. An example is a firewall coupled with an intrusion-detection system (IDS). Defense in depth provides security, because there's no single point of failure and no assumed single vector for attacks. It is for this reason that a choice between implementing network security in the middle of the network -- in the cloud -- or at the endpoints is a false dichotomy. No single security system is a panacea, and it's far better to do both. . The link for this article located at Schneier on Security is no longer available. .

network protectionsecurity measuresinformation securityUnderstanding Defense In Depth Concepts for Information Security
Perhaps the best way to visualize Defense in Depth as it relates to Information Security is to view the recent blockbuster movie: "The Two Towers". When the antagonists approached the perimeter defenses at Helm's Deep, they were first greeted by a volley of arrows. As they approached closer, rocks and boiling oil was thrown on their heads. Then there was the actual wall to contend with. As they brought up siege ladders, they were thrust back with long poles. As they jumped on the tower ramparts they were engaged hand to hand. But despite of the defenses due to the perceived value attached to defeating Rohan, evil nearly prevailed. As of late when one considers network and especially Internet security one might wonder if good will prevail in the real world. . . ..

But despite of the defenses due to the perceived value attached to defeating Rohan, evil nearly prevailed. As of late when one considers network and especially Internet security one might wonder if good will prevail in the real world. But while the unvigilant got hammered by SoBig.F and Blaster, we can rest assured that though internet functionality might be compromised, and we may not be able to see our bank account online, the data itself remains secure due to internal network defense in depth. While the bulk of the layers of network security occur inside the firewall, it is important to realize that most all data is on a network where virtually every other computer in the world has potential access. At the most course level,routers and network devices can achieve some degree of protection by filtering IP address. Routers function at the Network layer in the TCP/IP protocol stack and can thus see the IP addressing information. The router achieves this functionality through the use of ACL or access control lists. This can block certain IP addresses or certain ports and thus control traffic flow.
