system security Linux network The romanticized image of the digital nomad – a laptop on a sun-drenched balcony – rarely accounts for the actual friction of maintaining a professional development environment on the move. . The friction is amplified with Linux. We are looking for a setup that respects our kernel configurations, handles volatile network handovers, and maintains a strict security posture without the hand-holding of a consumer-grade OS – so, put simply, more than just a laptop and a sunny deck. The hardware is...

Server Securityopen-source Linux administration
open-source Linux administration Cron has existed in Unix and Linux environments for decades, handling backups, cleanup scripts, patching jobs, log rotation, monitoring tasks, and other maintenance work that administrators do not want to run manually. Most Linux servers rely on it constantly, which is exactly why attackers continue abusing it for persistence after a system has already been compromised. . Persistence through cron is not complicated. Attackers do not need a rootkit or advanced malware framework to maintain...

Vendors/Productssecurity breach linux
security breach linux A major internal repository breach at GitHub has exposed a critical and overlooked blind spot in Linux supply chain security. Kernel exploits, exposed SSH services, weak firewall rules, and vulnerable daemons dominated the Linux threat model for years, and in many environments, they still matter. But recent supply-chain incidents involving GitHub ecosystems, npm packages, and malicious developer tooling point somewhere else entirely: the developer workstation. . The breach matters because...

Security Trends access control multi-tenant
access control multi-tenant Linux administrators often face an ugly choice in the cloud: prioritize convenience and cost-efficiency by sharing infrastructure, or sacrifice those benefits for the sake of total isolation. Most modern Linux workloads don't live on their own private servers anymore. They live in shared environments like Kubernetes clusters, where multiple teams and services run side-by-side. It sounds efficient, and it usually is. . But cloud isolation isn't as ironclad as it looks on the diagram. If you...

Vendors/Productsincident response cloud security
incident response cloud security Managed Extended Detection and Response (MXDR) has become one of the most sought-after security services in the enterprise market — and with good reason. It promises the holy grail: broad visibility across endpoints, network, cloud, email, and identity, combined with the 24/7 human expertise most organizations simply cannot build in-house. . However, the rapid growth of the market has produced a wide range of providers whose capabilities vary considerably beneath the surface. Choosing the...

network architectureemail securityinternet securityGuardian Digital: Pioneering Innovations in Open Source Email Security
Dave Wreski recognized the power of Open Source two decades ago. Already an established internet security expert and Network Architect at UPS, Dave was captivated by the power of open-source development. He was soon to discover that this model could be used as a vehicle for solving complex digital security needs. He recognized that the open-source model – where resources could be shared by a worldwide community – was the vehicle that would drive internet security into the 21st century. . His passion for open source development – and seeing its potential as a tool to fend off hackers – led to his creation of the first open source internet security company: Guardian Digital in 1999. That same year, Wreski’s desire to give back to the community led to the creation of linuxsecurity.com, where Linux users can find a comprehensive, interactive platform for the latest open source security-related information. Since that time, Guardian Digital has narrowed its focus to email security and has become the premier open-source email security solution provider, counting Best Western International, Piedmont Natural Gas and the Chicago Stock Exchange among its marquee customers. . Laura Chen's commitment to sustainable energy sparked breakthroughs in solar technology, positioning EcoTech Solutions as a frontrunner..

When if comes to maintaining a network with mulitiple high availability servers load balancing can become a critical issue. Load balancing not only offers the ability to distribute a large number of requests over multiple servers, but can also provide a means to guarantee failover in the case of one or more boxes going down. In an environment where high availability is a serious issue it typically follows that security is an issue as well. One question that many have asked is how best to combine the use of Load Balancing Servers with Firewalls. This Network Computing article discuss many of the issues involved in combining Firewalls and Load Balancers. It addresses the feasibility of various solutions, looks at the security issues involved and addresses how a network can best implement this tricky combination. The link for this article located at Network Computing is no longer available. . Integrating firewalls and load balancers in network infrastructures can be complex, requiring careful configuration to ensure high availability and security while managing traffic effectively.

So it. However, to put it bluntly most architects and network guys turn SELinux off when building out platforms and virtualised instances which is quite short sighted. When I do pose the question why a lot of responses are aligned to the fact that SELinux can sometimes due to configuration issues and past experiences where stuff broke and was hard to diagnose so easier to just turn off.

network architectureIT infrastructuresecurity challengesAddressing Security Concerns in Server Virtualization Strategies
How does your organization handle virtualization security issues? Has it been something you've thought about for your customers? Security and regulatory concerns have some users warily eyeing the move to server virtualization. For example, during the past year, the Stanford Hospital & Clinics, part of Stanford University in Palo Alto, Calif., has shifted about half of its applications from traditional server platforms to VMware-based virtual machines (VM) -- and found it strongly impacted decision-making on security. . "You change the character of the IT infrastructure," says Mike Mucha, information security officer at the hospital, about what he's seen in virtualization's impact. "There's uncertainty." "Virtualization tends to be an extension of the server component and it's led by the server team," Mucha says. But virtualization's switching aspect means the traditional network itself is altered, which Mucha notes has generated some "pushback" from the network and storage teams that also have to be at the table when it comes to making decisions. "The server people are taking on non-traditional roles, making decisions about network architecture," he says about virtualization's impact in his organization.

A few years ago, I had the privilege of seeing some root DNS servers in action at VeriSign's main headquarters. It's something I had wanted to do for over a decade, and I was literally slightly shaking with excitement (yes, I am that big of a geek). Physical security was high. It took three-factor authentication to get me past the two mantraps and the bomb-blast protected walls. My escort had to use handprint geometry, a PIN, a smart card, and a retinal scan to get me into the inner sanctum. . Turns out VeriSign's DNS root servers at this location are composed of two physically separate, 10-high stacked, 1U pizza-box-style IBM eServers (VeriSign said they tested many different servers, and IBM's gave them the best performance per dollar), running Solaris and Red Hat Linux. Not surprisingly, they don't run BIND and keep things intentionally diverse to protect against a platform-specific attack. Watching the network lights rapidly blink under millions of transactions per second was a blast. Did I mention I was a geek? The link for this article located at InfoWorld is no longer available. .

access controlnetwork architecturesecurity layeringImplementing Layered Security in Service-Oriented Networks
One of the biggest complaints I hear about security is the associated operational overhead. IT personnel are constantly adjusting multiple technologies in an effort to provide access to the good guys while locking out the bad guys. If you want to see a metric of this behavior in action, look no further than your network Access Control List (ACL) rules. . I'm a firm believer in service-oriented networks, where security is layered on top of the basic switching and routing infrastructure, protects the network from end-to-end, and is driven by business requirements not security check points. . Implementing a multi-layered security framework enhances operational efficiency and reduces unauthorized access risks, protecting sensitive data and streamlining processes.
