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...

encryptionremote accessVPNCreating a Secure Tinc VPN for Reliable Remote Access Solutions
With tinc you can create a virtual private network (VPN) that lets you communicate between two machines over an insecure network such as the Internet with all of your traffic encrypted between the hosts on your virtual network. Another interesting application for tinc is connecting your laptop to a Wi-Fi router at home. You might already be using WPA2 to ensure that only valid hosts can connect and communicate with your Wi-Fi router, but you might not be able to assign a fixed address to the laptop when it is connected over Wi-Fi. So if you want to connect to an SSH daemon on the laptop itself or access an NFS share on the laptop, you have to play guessing games as to which IP address the Wi-Fi router has given the laptop this time. Running tinc on the laptop and a server at home removes the guessing game -- just connect to the laptop's VPN IP address. This is an interesting article for anyone who is thinking about setting up an VPN. It talks about using a tool called tinc. . The link for this article located at Linux.com is no longer available. .

If you're interested in setting up a wireless network at your company, this guide will walk you through the steps needed to evaluate the role wireless networking technologies might play in your company's overall networking solution, and help you understand the steps you need to take to implement the solution. . . .. Wireless networks are becoming faster, more affordable and easier to adopt than ever. Growing small businesses that have adopted a wireless solution are already reporting immediate paybacks in higher productivity, flexible application mobility and greater worker satisfaction. Roughly 228,000 small businesses currently have remote access capabilities built into their networks for security monitoring, and according to America Marketing Institute, the number will double over the next 12 months.

The San Antonio installation is home to the commanders of the Army's medical systems and supports various military training services, including battle simulation. Because other tactical groups often conduct tests at the site, a network may be installed for a week, a few months or even a year. On top of this, the base has 18,000 computer users and houses a number of older buildings, so running high-speed copper or fiber wiring is expensive, impractical and sometimes impossible. Wireless local-area networks based on the popular 802.11 standards emerged as the best way to expand the base's network last year because of the easy setup and breakdown, and the minimal disruption to the existing infrastructure.

This article discusses a network setup which might prove useful for people who like to put some extra effort into connecting their machines to the Internet. The goal is to build a secure client and server farm on a single IP address. Next to the clients and servers, the network contains two other components. The first one is a Network Address Translator (NAT), which makes it possible to connect more than one machine to the Internet using just one IP address. The second one is a Packet Filtering Bridge (PFB) that transparently filters IP traffic from and to the Internet. The link for this article located at daemonnews is no longer available. .

This part of the article gives an overview of ways to use your DSL machine as gateway for your home or office network, and goes through the basic steps to setup and maintain security to machines connected directly to the Internet. With NAT (or "IP masquerading", as it's called in another universe), multiple machine can be hidden behind one gateway machine. The machines behind the gateway can use their own, private network numbers (usually form the 10/24 or 192.168/16 subnets), and the gateway will translate the private, internal addresses to the public, external address of the gateway machine (hence NAT => Network Address Translation, see Image #3). Any replies made to requests sent out will be translated before sent back to the client. One of the characteristics of this scheme is that a client machine needs to establish a connection, and no outside machine can connect beyond the NAT gateway. From the security point of view this is absolutely desirable. From a practical view, it might be needed to forward single ports to inside machines, e.g. to let them handle WWW or FTP requests.

The first thing I did upon getting cable modem access in my apartment was to get an old Pentium 133 computer, put in two NICs, and fire up the OpenBSD 2.7 boot floppy. I did this for several reasons: first, because I heard that OpenBSD runs as a fast network node even with old hardware; and second, because I knew that it was probably the most secure operating system I can get in that price range. While some people may view OpenBSD security as overkill for a simple home cable modem setup, upon closer examination I found that OpenBSD's secure upon install feature did save my butt more than once; right now, the logfiles show that (literally) not an hour goes by without my system being scanned by someone on the internet.
