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...

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...

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 protectionsecurity enhancementopen source toolsEnhancing Linux Server Security With Top Open-Source Tools for 2022
Learn about 10 great open-source tools to improve the security of your Linux servers heading into 2022. . Since I started learning about computers I have heard many experienced users saying Linux is impenetrable, Linux offers the best security, and such. It is partly true that Linux offers various security measures which mitigate attacks and stop hackers from breaching your system network. But you should also understand that just by deploying Linux on your server or PC you are not done yet, you have to configure all the necessary tools and apps. As the security features are not enabled by default, and if you are scared of network breaches and security leaks, then this should be the first thing you should be doing after installing the Linux OS. Remember your security system always depends on the tools you use, it’s the tools’ features that sniff out any malware in the system, prevent security breaches from happening, and find out vulnerabilities to deploy countermeasures. In short, the cybersecurity for a network or terminal is based on the tools, not on the default security measures of the OS. .

two-factor authenticationidentity managemententerprise securitySymantec's $1.28 Billion Acquisition of VeriSign's Security Division
In case your boss ever questions whether security is big business... Symantec will pay US$1.28 billion to acquire VeriSign's security business. The two companies confirmed the rumored acquisition, saying it would give VeriSign the opportunity to focus on its more-profitable domain name business, while allowing Symantec to broaden its growing portfolio of enterprise security products. l.. "There is a real need to be able to know who the user is and what they should have access to... but without the central theme of identity we weren't able to provide the total solution," Symantec CEO Enrique Salem said during a conference call to discuss the deal. "IT needs to be able to control the information, and identity matters to be able to provide that solution." Reports surfaced Tuesday that VeriSign had been shopping around its encryption technology and service business, and naming Symantec as the buyer. The VeriSign business unit sells SSL (Secure Sockets Layer) certificates -- used to authenticate secure Internet servers -- two-factor authentication tokens, fraud detection and public key infrastructure products for government and the enterprise. But the business has grown slowly of late, hurt by dropping SSL certificate prices, a fact that is reflected in the unit's low purchase price relative to its $371 million in annual revenue. "If you want to succeed in that market you have to have a lot of services, the platform, large and growing distribution channels -- a lot of things that Symantec has," Mark McLaughlin, VeriSign's president and CEO, said on the conference cal The link for this article located at Tech World is no longer available. .

The government team leading the development of a security gateway designed to authenticate users accessing e-government services asked industry last week for possible solutions to make the initiative a reality. The "technical exchange day" held June 7 at Mitretek Systems Inc., the nonprofit organization assisting the General Services Administration-led team on the E-Authentication project, was the first chance for government to outline its plans to a large industry gathering. The lack of a defined technology architecture surprised many of the vendors attending the briefing, but Tice DeYoung, the e-authentication project's technical lead and a research scientist at NASA, said the government did not want to restrict itself to any specific architecture or particular products.

Whether you run a small business or large corporation -- or just have a desktop PC at home -- if you're connected to the Internet for any amount of time, you need a firewall to keep your data safe. People with ill intentions will try everything from stealing your credit card data, to exploiting open mail relays for spam, or even manipulating potential (and unwitting) participants in Distributed Denial of Service (DDoS) attacks. You must decide what kind of firewall you need, and whether you want to set it up yourself from scratch or have a little help. It's certainly possible to install just about any Linux distribution, or one of the *BSDs, and configure that to run as a firewall. For the more technically inclined, it's not difficult. However, most of us would rather spend our quality time doing something other than configuring a firewall from scratch. The link for this article located at UnixReview.com is no longer available. .

This is a great document that explains public key infrastructure, X.509 and certificates, and the problems with existing methods. "Conventional PKI, built around ISO standard X.509, has been, and will continue to be, a substantial failure. This paper examines that form of PKI architecture, and concludes that the reason for its failure is its very poor fit to the real needs of cyberspace participants. Its key deficiencies are its inherently hierarchical and authoritarian nature, its unreasonable presumptions about the security of private keys, a range of other technical and implementation defects, confusions about what it is that a certificate actually provides assurance about, and its inherent privacy-invasiveness. Alternatives to conventional PKI are identified." The link for this article located at Roger Clarke is no longer available. .

Security was a hot topic at Monday's first-ever federal Linux user's conference. The news that Microsoft Corp.'s network had been breached and that hackers had gained access to source code underscores the need for effective security systems to protect large institutions -- like the government -- from such attacks, said speakers and delegates alike at the conference here. While many people view the Linux operating system with suspicion, believing it to be even more vulnerable to security breaches and attacks than other systems, this is not the case, said Piers McMahon, a senior security business manager at Computer Associates International Inc. in Islandia, N.Y.
