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...

threat analysiscybercrimecybersecurityMan-in-the-Browser Threats: Risks to Corporate Networks and Data Security
Cybercriminals are increasingly targeting the information assets of some of the world's most well-known organizations, according to the findings of a recent global study by McAfee and Science Applications International Corp. (SAIC) entitled "Underground Economies: Intellectual Capital and Sensitive Corporate Data Now the Latest Cybercrime Currency.". With firewalls, antivirus and other security mechanisms protecting corporate networks, how do attackers manage to penetrate enterprise computer systems? Simply by exploiting the weakest link in the security chain. One of the newest methods is tunneling in via employees' browsers using an attack known as "Man-in-the-Browser" (MitB).

You can't manage what you can't see. So it's not surprising that with corporate networks congested more and more by P2P, streaming media, and other "leisure" traffic, network admins are increasingly turning to specialized network management software packages and appliances to give them the information they need to take back control of their bandwidth. Of course, if your network is uncongested, network logons are quick, and users find all their business applications are running at top speed, then you're probably not too concerned about a handful of people using KazaA somewhere in your organization. Sadly, though, this ideal state of affairs is rarely witnessed, except perhaps in administrators' dreams. The truth is that most corporate networks carry far more network-clogging leisure traffic than they can cope with. That's because leisure apps are often particularly aggressive bandwidth users.

At a time when protecting corporate networks is paramount, many users are steering clear of a feature of IP Security VPNs called split tunneling, a move that can give a false sense that remote-access networks are more secure than they really are, experts say. Split tunneling was created to allow Web surfing and corporate VPN access simultaneously from remote PCs. The benefit of split tunneling is that corporations can conserve bandwidth needed for Internet access at VPN hub sites and reduce the load on VPN gateways.

As corporate cybersecurity gains importance, many employees hesitate to use split tunneling, uncertain about its security risks while working remotely.

Speaking at the First International Security Users Conference in London, Adrian Wright, managing director of Secoda Risk Management, warned that junk emailers are taking advantage of unprotected wireless local area networks to bombard email users with unsolicited and unwelcome messages.

Products designed to boost security for mobile devices and on corporate networks are two of the main themes here at RSA Conference 2001 this week, with Motorola, Japan's Matsushita Electric Industrial, and the Internet division of Nokia all announcing new security moves and partners. Motorola announced that VeriSign is providing it with an alternative technology to digital certificates for use in mobile phones and other wireless devices. The processing power available in wireless gadgets is limited, so devices cannot always check to see if a digital certificate has been revoked, the companies said. VeriSign has developed a system that issues a new digital certificate every 24 hours, which makes it easier to secure transactions on mobile devices, the companies said.

A new technique for disguising programs aimed at cracking corporate networks could raise the stakes in the heated battle between hackers and security experts. During a seminar last week at the CanSecWest conference in Vancouver, British Columbia, a hacker named "K2" revealed a program he created that can camouflage the tiny programs that hackers generally use to crack through system security. The cloaking technique is aimed at foiling the pattern-recognition intelligence used by many intrusion detection systems, or IDSes, known as the burglar alarms of the Internet. "Trust me, this will blow away any pattern matching," said K2, who would not reveal his real name because he also works as a security consultant. When a security hole is found on a corporate network, hackers usually will find several ways to exploit it. To manage the onslaught, the makers of intrusion-detection systems continually update their own software to keep track of new variants of an already familiar theme.
