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...

Telecommunications giant Sprint announced plans Tuesday to launch a private IP network aimed at security-conscious U.S. government agencies by late June. The new network, which doesn't yet have a name, will mimic Sprint's SprintLink enterprise-class, IP backbone network and offer most of the same features, except that it won't be connected to the public Internet. Sprint expects government agencies that want to be especially protective of data to be the first customers, said Steve Lunceford, a Sprint spokesman. The "government-grade" private Internet should have one or two government agencies as its customers by its launch in late June, he added. The Sprint service is designed to ease customer worries that "someone in an Internet cafe in Beijing could get into the network," Lunceford said. Customers using the private network would have to use SprintLink or another public backbone for outside e-mail or Web surfing, but individual users won't be able to tell when they're switching back and forth, he added.

The most popular technique, tunneling, entails wrapping private network packets inside TCP/IP data sent via the Internet. Hardware or software on both ends of this VPN connection use a shared encryption key to encrypt and wrap and then unwrap and decipher VPN packets. VPNs leverage companies' existing Internet service to eliminate the cost and management burden of single-purpose leased lines and modem banks. A VPN is not a perfect solution because it is sensitive to all of the problems that plague the Internet, including latency (packet delivery delays), packet loss, and routing failures. Every potential VPN malady is matched by an equally troubling private network issue, but VPNs create a unique dilemma: When you ship private information along a public network, how do you keep that information safe?

First, the proxy server acts as an intermediary, helping users on a private network get information from the Internet when they need it, while ensuring that network security is maintained. Second, a proxy server may store frequently requested information in a local disk cache, rapidly delivering it to multiple users without having to go back to the Internet to get it. A proxy server is usually just one component of software that provides a variety of other services, such as a gateway to connect the local network to the Internet or a firewall to provide protection from outside intrusion. Because proxy servers and firewalls are so often bundled together, people often confuse the two. However, a packet-filtering firewall operates at the Network layer of the OSI model, while proxy servers work at the Application layer. Packet filters use routers to filter information coming to and from a network. Because routers check each packet against some sort of access-control table (listing, for example, the IP addresses of trusted servers), they make it easy to block traffic that's not trusted. Firewalls can also screen packets based upon TCP and UDP port numbers; therefore, you can permit certain types of connections (Telnet or FTP, for example) to only certain trusted servers.

"IPSec is beginning to support key business and technology objectives such as B2B extranet backbones and dial access VPN's for remote computing. Despite the security and operational benefits of a VPN, the problem of authenticating client entities for access control decisions remains a risk management issue. Providing needed protection in specific situations, many system designers have recommended authorization services be placed at the application layer. This approach using security specific API's to shunt security services into existing application code can be a lengthy process. Conducting identity authentication and authorization of client entities (a person or program) within the encrypted network tunnel, similar to the (SSL) Secure Sockets Layer model has widespread application and works to protect specialized content (such as a login dialogue box) on Web servers.

Because the tunnel appears to the IP level network code as a normal network device, there is no need to adapt any existing software. This tunneling allows VPN sites to share information with eachother over the Internet without exposing any information to others. A single tinc daemon can accept more than one connection at a time, thus making it possible to create larger virtual networks, because some limitations are circumvented.
