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...

data protectionnetwork protocolswireless encryptionWi-Fi Security Perspectives: Assessing Future Enhancements and Challenges
While the past of Wi-Fi has been plagued with security problems the economics are such that many players in the IT market want to see the insecure WEP replaced with something more robust. While nothing in the future is certain, it seem a given that Wi-Fi will overcome its adolescent growing pains and mature into a reasonably secure and easy to deploy method of networking. . . .. While the growth of 802.11b wireless networking has been explosive, problems with security of data being transmitted have plagued the technology almost since its conception. Still in spite of its drawbacks 802.11b has some compelling reasons for its deployment, both by the consumer and in the enterprise. Those reasons include its low cost, its ease of deployment and the tremendous convenience that wireless networking offers. As anyone knows who remembers the old Party Line telephone system, some times lack of good privacy can be lived with. Risk in general is discussed as well as basic ways to mitigate the risk. While Wireless Fidelity's (Wi-Fi) main security algorithm Wireless Encryption Protocol or WEP as it is commonly referred to remains relatively easy to crack, it is still better than nothing. This and other counter measures are discussed from basic residential wireless setups to more advanced ways the enterprise environment might consider for deploying wireless for transmission of important corporate data. While data security, confidentiality, integrity and user or access point authorization has left much to be desired in Wi-Fi's past, the future of Wi-Fi seems, at least at present to be brighter. Perhaps the main reason for this has been Wi-Fi's tremendous growth, which makes many of IT's main players want to see it succeed. WPA, 802.11X and other technologies have support of such industry giants as Microsoft and Cisco. So while secure wireless computing is still not a reality, it is a technology that merits close watch for the enterprise. The link for this article located at ebcvg.com is no longer available. .

Cisco Systems this week introduced an architecture designed to make wireless LANs easier to manage and more secure. Cisco's Structured Wireless-Aware Network framework, which includes a series of enhancements and additions to its hardware portfolio and new software capabilities, are also designed to head of the threat of competitors using wireless LANs as a bridgehead to attack Cisco's core enterprise networking market. Cisco's pitch is that its framework provides the security, scalability, and reliability that enterprises need to run core business applications over a wireless LAN network. To enjoy these benefits to the full, corporates need to standardise on a Cisco-only network. "The advantages of a 'wireless-aware' Cisco switch and router infrastructure combined with a Cisco wireless network include a common management and robust security scheme, simplified deployment and operation, centralised control and configuration of thousands of networking devices, the ability to detect rogue access points, fast secure roaming for mobile applications and self-healing networks for improved wireless up-time," the pitch continues.

Having graduated from the realm of adventurous small offices and hard-core enthusiasts, wireless networking is now thriving in the enterprise. And with new standards just around the corner, wire-free networks based on the 802.11 protocol are here to stay . A wireless network acts much like a wired network, with a few notable exceptions. On the positive side, a wireless network gives users the freedom to roam around the office while maintaining connectivity to the network. It also frees systems administrators from the burden of having to string wire to various locations throughout the building. However, wireless networks come with plenty of drawbacks as well. Perhaps the most serious of them is weak security. The link for this article located at ComputerWorld is no longer available. . With wireless networks evolving through new 802.11 standards, enterprises need solid security strategies. Here are key approaches to enhance wireless security..
