Siem Architecture Hero Esm H350
Price Tag 1threat detection scalability

Building a SIEM is easier than scaling one. Most open-source deployments start as a simple "all-in-one" server. It is easy to set up, but that design rarely survives the transition from a lab to a production workload. . A SIEM watching 20 endpoints is not doing the same job as one watching 500. More endpoints mean more logs; more logs require more storage; more storage makes search heavier. Eventually, the very architecture that made your lab easy to deploy becomes the reason your production...

Http2 Bomb Hero 2026 Esm H350
Price Tag 1security advisory apache

A newly disclosed attack technique called HTTP/2 Bomb is drawing attention because it targets the software that sits at the front of much of the Linux internet. Apache HTTP Server, NGINX, Envoy, and the ingress layers that many Kubernetes environments depend on can be forced into consuming disproportionate amounts of memory using relatively small amounts of attacker traffic. . For Linux administrators, the concern is not the HTTP/2 protocol itself. It is the possibility that a single...

Supply Chain Risk Starts At The Workstation Hero Esm H350
Price Tag 1security advisory important

The compromise of Nx Console shows how much infrastructure now sits behind a single developer account. GitHub repositories, CI/CD pipelines, container build systems, Terraform projects, Kubernetes deployments. None of those systems was the initial target. The workstation was. . Attackers did not need a Linux privilege escalation bug or a remote code execution chain. They needed developers to trust a tool they were already using. For many organizations, that was enough. What Happened? Federal...

Persistence Tricks Hero Esm H350
Price Tag 1security advisory open-source

You remove the malware. You rotate the compromised credentials. You patch the original vulnerability and close the ticket. Two weeks later, the attacker is back. . What happened? You didn't lose the battle at the exploit; you lost it at the cleanup. In many modern Linux intrusions, the malware you found wasn't the main problem—it was the fallback mechanisms left behind. These hooks quietly restore attacker access the moment you look away. If you clean a host but miss these persistence layers,...

Red Hat Npm Hero Esm H350
Price Tag 1security advisory Red Hat

Researchers investigating a campaign now tracked as Miasma found that more than 30 packages in Red Hat's @redhat-cloud-services npm namespace had been altered to deliver credential-stealing malware. . The packages weren't being used to deploy ransomware or sabotage systems. From what has been reported so far, the objective appears to have been much simpler: collect credentials from developer environments and use that access elsewhere. GitHub tokens, cloud credentials, SSH keys, and other...

Nmap: Celebrating 10 Years as a Leading Network Mapping Tool

This February, the team at Linuxsecurity.com has chosen NMAP as the Open Source Security Tool of the Month! In January, we chose GnuPG in part because it had just celebrated its 10th anniversary. Well, it wasn't alone. As of this past December Nmap ("Network Mapper"), the free and open source utility for network exploration and auditing, celebrated its 10th Anniversary as well! And because of its popularity, chances are very good that you've already used NMAP for quite some time. Even if you have, it's always good to take a look at how it all got started and what it's all about... . What has really made NMAP such a staple of network security configuration is that its capability was the result such a strong communal need. As is the case with so many open source projects, NMAP followed a path that really mimics "necessity is the mother of invention." As huge networks began to take shape, as the Internet took its hold within businesses and schools, and as users everywhere started to understand and protect their network, a similar story kept popping up: 'I need to know the information is passing between my network and the Internet and I have to track X ports on X machines to do it.' So how many is X? A number that screams "I need something heavy-duty and automated." And so it was in 1997, while fulfilling the role of TA at Johns Hopkins University, that its creator Fyodor was presented with a dorm room, access to a large network and some insufficient tools. Some of them did one job. Some did another. And yet, even after modifications, none of them (Strobe, Reflscan or UDP) really seemed to do what was needed. So, during the summer of that year he hacked together a robust scanning tool and that September, the first official version of NMAP was released. It was gloriously received by users around the world; which, by community standards, equates to a huge influx of bug fixes, ideas and suggestions on how you should take your code and start again.  (Of course, this is what thecommunity is all about The link for this article located at is no longer available. .
