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...

network securitytraffic analysisweb serverData Attacks Using HTTP Tunneling: Defense and Mitigation Strategies
As more traffic across the Internet is coming under scrutiny and network administrators are making efforts to limit the traffic in and out of their networks, the one port that no one is willing to block en-masse is port 80. Users (and administrators) browse the web constantly, whether it is for work purposes or not. The lifeblood of a company's existence on the Internet requires a web presence in one fashion or another and this requires a web server, whether it is hosted by a service provider or located on a company's network. . . .. As more traffic across the Internet is coming under scrutiny and network administrators are making efforts to limit the traffic in and out of their networks, the one port that no one is willing to block en-masse is port 80. Users (and administrators) browse the web constantly, whether it is for work purposes or not. The lifeblood of a company's existence on the Internet requires a web presence in one fashion or another and this requires a web server, whether it is hosted by a service provider or located on a company's network. With every new worm, bug, or vulnerability found in IIS and Apache servers, network and secop administrators are trying to lock down these systems further at the router or firewall. To identify attacks many are turning to IDS and IPS. In this article we will look at a means to bypass the access control restrictions of a company's router or firewall. This information is intended to provide help for those who are legitimately testing the security of a network (whether they are in-house expertise or outside consultants). This article, by no means, condones the use of this information for the purpose of unauthorized access to a network or a system. Finally, this article will provide some pointers on how to defend against this attack. The link for this article located at securityfocus.com is no longer available. .

On October 21, 2002, people around the world cruised through cyberspace the way they do every day -- bidding on auctions, booking airline reservations, sending e-mail -- all the while unaware that someone was working overtime to try to bring the Internet to its knees. Around 5 p.m. Eastern time, operators of the Internet's root servers, the computers that provide the roadmap for all online traffic, saw an unnaturally large spike in the amount of incoming data. It was a "distributed denial-of-service attack," a concentrated attempt to throw so much information at the servers that they would shut down.
