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...

data protectionencryptionprivacyExplore The Top 5 Open Source VPNs For Enhanced Privacy In 2020
We’re living in times where internet privacy could soon become a myth with companies putting in their best foot to get hold of our data for advertising and other purposes. Thankfully, we still have VPNs to browse the internet anonymously. However, the recent case of one of the most popular VPNs falling prey to hackers further complicates the issue. . So what’s the solution? Open source VPN. We’re not saying that open source VPNs aren’t prone to hacking but as the reputation of open source products precedes, we can consider these to be safer than closed source VPNs. One of the benefits of using an open-source VPN client as compared to a custom VPN is the fact that all the source code of the VPN apps is public, which ensures that the company isn’t hiding anything from you. Open source VPNs use SSL/TLS protocol for encryption. The link for this article located at Fossbytes is no longer available. .

With the prevalence of . So where is the appeal of creating your own firewall system? Take a look at some of the many extra features available in a do-it-yourself firewall. While such a firewall system would be self-contained, require a fair amount of storage, run on over-powered hardware, and consume more electricity than a simple appliance, the benefits still far outweigh the drawbacks. For one, there is a higher degree of reliability. Running on a full computer system makes it infinitely upgradeable. It can be extended to do more than just shuffle packets back and forth. You can turn a simple firewall into a full intrusion detection system. You can analyze and track bandwidth usage. It can be a VPN end point, a Web proxy, DHCP and DNS server, load balancer, handle automatic failover, and provide great diagnostic tools.

Virtual private networking is becoming an integral part of today's data networks.

Virtual private networking is becoming an integral part of today's data networks. Virtual private network (VPN) drivers range from securing corporate communications to reducing costs by replacing leased lines. But for those who have not yet deployed a VPN, the options can be daunting. There are several approaches and dozens of products and services from which to choose, each with its own pros and cons. Let's take a look at the various solutions and how they apply to different environments. There are two types of VPN technologies used on the Internet today: the trusted VPN and the secure VPN. Trusted VPNs are provisioned and managed by Internet service providers by defining paths through their networks to ensure that customers' traffic is routed over a trusted path. A customer might choose a trusted VPN because there is no equipment to buy, it's completely managed by the service provider and thus requires no maintenance, and they often include service-level agreements. Typically, trusted VPNs are less expensive upfront but more expensive over time. The link for this article located at ComputerWorld is no longer available. .

Explaining IPSec, different levels of security and how to be safe sending and receiving packets over the network. .. VPNs (virtual private networks, i.e., private networks deployed over a public packet infrastructure) are definitely emerging as the solution of choice for the interconnection of distant offices belonging to the same company. Unfortunately, IP packets carry our precious data in a clear form that is easily intercepted by malicious users. Doing this on a common Linux-based PC is actually quite easy, provided that one has access to the network segment over which the desired packets are traveling. Several different solutions exist that allow us to cope with this problem, each operating at a different level of abstraction. In this article, we will discuss the differences between and purposes of application-level security, socket-level security and network-level security.

FreeS/WAN is an ideal solution for the overworked, harassed network admin who needs to bring together branch offices, telecommuters, and road warriors from anywhere over the Internet, and it does it all for the price of the hardware, with requirements that are surprisingly low. S/WAN is short for Secure Wide Area Network. FreeS/WAN is a free Linux implementation of IPsec (IP security) protocols. IPsec is built into IPv6, and is optional for IPv4, the current IP (Internet Protocol) deployment. IPsec provides two levels of protection: encryption and authentication, at the IP level of the network protocol stack. Because IPsec operates at the network layer, it secures nearly any type of Internet traffic. One common scenario creates a secure 'tunnel' between two networks, over an untrusted network; in effect, creating a single large private network over the Internet, or inside any company or institution with departments that need to protect their data. Another common scenario is creating a secure connection between a network and a single remote host. The link for this article located at Earthweb is no longer available. .
