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...

web securitycyber threatencryption protocolSSLShading Enhances Web Security Against Cyber Threats Like Firesheep
Researchers have found a cheaper, faster way to process SSL/TLS with off-the-shelf hardware, a development that could let more Web sites shut down cyber threats posed by the likes of the Firesheep hijacking tool.. The technology, dubbed SSLShading, shows how SSL proxies based on commodity hardware can protect Web servers without slowing down transactions, according to a presentation scheduled at the USENIX Symposium on Networked Design and Implementation in Boston March 30 through April 1. SSL/TLS -- the cryptographic protocols used to protect online Web transactions -- encrypts traffic from visitors' machines all the way to Web servers. That makes it impossible to pick up data such as session cookies by preying on unencrypted wireless networks, which is what Firesheep does.

The advancement of TLSGuard technology illustrates the efficacy of budget-friendly TLS proxies in bolstering online protection from vulnerabilities such as Wireshark..

security advisoryinternal securityfirewall configurationConfiguring A Linux DMZ: Essential Setup For Secure Networking
(The)Demilitarized zone, used to secure an internal network from external access. You can use Linux firewall to create DMZ easily. There are many different ways to design a network with a DMZ. The basic method is to use a single Linux firewall with 3 Ethernet cards. The following simple example discusses DMZ setup and forwarding public traffic to internal servers. There's a little advanced know-how required here and he recommends a couple good firewalls to set up such functionality just in case this very useful guide doesn't fit the bill. If you are looking to set up a Linux Demilitarized zone a couple of options include EnGarde, IpCop and others. . The link for this article located at is no longer available. .

risk managementsecurity insightssystem administrationReview of Linux Server Security Insights for System Administrators
Staying on my current security theme, O'Reilly has published a second edition of Linux Server Security by Michael D. Bauer. The book, targeted toward those managing Internet-connected systems, also known as bastion hosts, packs a powerful arsenal of security design, theory and practical configuration schemes into 500 pages. . Bauer gained some notoriety from his Paranoid Penguin columns in the Linux Journal Magazine, which ultimately inspired the book. What stands out prominently is the time Bauer took to introduce network security design and risk management before digging into the hands-on nuts and bolts. As business models change for web professionals, many developers find themselves donning at least a part time system administrator's hat. Understanding how underlying network designs work and how specific configurations can prevent attacks are critical before jumping into a command shell and making changes on a production server.

Corporate network security is increasingly becoming a design consideration rather than a matter of "retro-fitting" security appliances and software, according to industry consultants. Alphawest's national business continuity manager Tim Smith said the company has seen a new trend this year in networks being designed to meet security concerns. "Like anything, if you have the opportunity to build it from the start it should be more secure. In some cases companies are doing complete network re-designs for security purposes," Smith said. Smith said the main security consideration is determining the critical assets which must be considered in network design. "One of the turning points in secure network design is a move to tidy up what is in place," he said. "Before you can continue to build in security you need to clean up." . Business network safety is increasingly a design priority, highlighting the need for integrated security measures within network architectures..

The 802.11 specification has some clear authentication discrepancies that create security headaches for WLAN design engineers. In Part 2 of this series, we'll examine the 802.11 authentication mechanisms and the security problems they provide. By its nature, the wireless medium provides inherent security challenges for today's wireless LAN (WLAN) system designers. Developers of the initial 802.11 specification tried to tackle these security concerns head on. These efforts, however, have fallen short, making questions around WLAN security even more intense. This is the second part in a three-part series on securing WLAN links. In Part 1, we examined the inherent challenges with the wireless medium. Now, in this part, we'll look at the security challenges plaguing the 802.11 specification. Part 3 will continue this discussion, providing security solutions for WLAN designers.

Just read this issue cover to cover, and I guarantee a secure feeling will wash over you. Of course, it'll then be your responsibility to use this newfound knowledge to apply security in just the right amounts for your IT infrastructure. If you use wireless technology, run Linux or are considering an MPLS-based VPN service, read on. Some vendors (names removed to protect the ignorant) just don't understand how important an audience you are--220,000 professional technologists. You're the group that drives critical business technology decisions. Some vendors prefer to fixate on CxOs, thinking that their final sign-offs on purchase orders translate into their making technology decisions. But we all know that the CEO or COO isn't capable of, say, evaluating or debating the inherent weaknesses of WEP. If he or she were, why would a company need an IT organization? Thankfully, most IT products aren't selected just on the basis of a brand name or vendor-CEO relationship. Which brings us back to the security discussion. If vendors want your business, they must understand the importance of building security into the base design of a product--it can't be treated as a layered product.
