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...

data centerenterprise protectionsecure linuxCritical Security Measures for Government Data with Secure Linux
As the Linux operating system makes ever-deeper inroads into government data centers, agencies need to feel comfortable that the open-source computing infrastructures they're rolling out are indeed secure. In general, firewalls protect enterprise networks from intruders. But enterprises also require other types of protection in case a hacker gets past the firewall. Traditional Unix vendors have always provided added security at the operating-system level, including so-called "trusted" versions designed to provide data centers and security operations with machine-level security. These trusted versions defend against unauthorized access to data and applications. . The link for this article located at Government Computer News is no longer available. .

With recent technological advances, wireless devices are well positioned to add value as corporate productivity tools. Investments in this area have the potential to provide widespread improvements in mobile worker efficiency, business activity monitoring, exception handling, and organizational throughput. While the potential gains are impressive, many organizations are waiting to deploy this technology due to security concerns. Companies which wait may indeed feel secure. But companies which provide their workers with real time access to business critical information while addressing security concerns will have a significant competitive advantage. In this article, we will explore the security issues involved in wireless deployments, and appropriate steps for information technologists to take when establishing their wireless infrastructure, so that they can take advantage of wireless technologies while minimizing business risk. Security Overview A wireless security model should address potential threats not just in the corporate environment, but also in the personal and public environments where wireless devices are typically used. As a basic starting point, you will want to evaluate the level of exposure available through your devices, networks, data, and accompanying information systems. According to the Gartner Group, over 250,000 PDAs were lost in 2001. These losses occurred in highly public places - airports, restaurants, offices, taxi cabs, etc. Given the ease with which these devices are lost it is imperative that your securitymodel include a means for securing and removing information stored on the device.

security strategiessecurity managemententerprise protectionComprehensive Security Management Strategies for Enterprises
An optimal security posture, and one that eliminates the complexities of security management, is one that takes into account each of these four security disciplines. Adherence to best practices within these four fronts will reduce the costs of enterprise protection and lower risks while enhancing security resource allocation and inefficiencies. . . .. Securing your enterprise IT infrastructure can be a complex task. If your computing environment is like most, it is heterogeneous and contains a number of security products from many vendors. You may have diverse intrusion detection systems, VPNs, firewalls, antivirus software, and modems allowing remote users to dial into your network, along with offices in different geographic locations. Potential problems with this scenario aren't hard to find. Without a holistic view of the current security structure, how do you go about managing security? Security tools may work well on their own, but how do they work together to protect your network, and how do you monitor their performance? With today's organizations becoming more global, connected, and dynamic in nature, the idea and practice of information security has never been more complex. Consider the following challenges IT faces in protecting the corporate networking environment: * Each week, 60 new software vulnerabilities and 100 new viruses are identified. * Customers and stakeholders continue to demand greater levels of services via online systems. * Organizations face significant time, budgetary, and personnel constraints. Traditionally, organizations have relied on a point-product approach to address these issues. However, this has led to a new and seemingly impossible challenge: How to effectively and efficiently manage and mitigate the complexities of this security environment. Enforcing security policies and regulations Enterprises need to establish security policies, standards, and procedures to enforce information security in a structured way. Conducting a risk assessment will help you to identify andmanage the vulnerabilities in your environment. From there, you will be able to develop a proper policy framework and standards, and begin constructing a set of policies tailored for your enterprise. ISO 17799 is one of many government and industry based regulations and standards that enterprises are incorporating into their security policies. Your enterprise may also be subject to industry-specific security regulations such as HIPAA and GLBA. These outside policies need to be enforced, in addition to your own in-house policies. Establishing a security policy is one thing - effectively managing and enforcing them is quite another. Keeping access controls, authentication, and authorization measures up-to-date on all levels of your network is critical for a security policy to be effective. Any gaps in this information can increase your exposure to threats. Companies may have information security policies in place to protect critical assets and sensitive data, but they rarely have the means to effectively monitor compliance in accordance with that policy.

Unless you've been tinkering with the rovers on Mars and are just now returning to this planet, you've likely had your fill of the stories of the latest worm. And unless you're running SCO's Web site, you probably have had little more than inconvenience as a result of that fast spreading worm.Sure, it slowed down the Internet and generated prodigious quantities of e-mail traffic, but if you had already protected your enterprise properly, the biggest impact you felt was the constant stream of news stories in the mainstream media. We don't want to inflict any more of that on you, so I'm not going to write about the recent worm. It's already history, and you've got the satisfaction of knowing that your enterprise got through the epidemic just fine. That's important, because it's easy to focus on the issue of the moment, and lose sight of the fact that in spite of the worm, other security threats are more important. . . .. Unless you've been tinkering with the rovers on Mars and are just now returning to this planet, you've likely had your fill of the stories of the latest worm.

We don't want to inflict any more of that on you, so I'm not going to write about the recent worm. It's already history, and you've got the satisfaction of knowing that your enterprise got through the epidemic just fine. That's important, because it's easy to focus on the issue of the moment, and lose sight of the fact that in spite of the worm, other security threats are more important. For example, the Mydoom worm didn't have any effect on your need to keep your internal network secure from breaches within your organization as well as from without. It didn't affect theneed to make sure your physical security is up to snuff. And it didn't diminish the need to make sure your anti-virus practices remained in force, since all those other worms and viruses are still out there, waiting to break into your network. And of course, the worm had no effect on all of the other myriad duties you have on your plate. It just added a new distraction -- and a new temporary duty -- while you're making sure your management knows that yes, you're already prepared for the threats that you actually anticipated and prepared for months ago. That's perhaps the biggest downside of an attack like the one we just had -- that people who normally pay no attention to your network security (and most likely resent it) are suddenly experts for a day who want to look over your shoulder while you do your real job. After all, it's your real job that kept your company secure during this wormy week. Rather than dropping everything and clamoring about the worm-of-the-moment, you've taken a risk-based approach to your enterprise network. You know what you need to do to prevent nearly anything from bringing your network down, and you've already done it. The link for this article located at infoworld.com is no longer available. .

We challenged networking and firewall vendors to design an enterprise that's secure from the perimeter to the core. Their responses give us a glimpse into the future of network security. Remote connectivity, partner extranets, supply chains, on-site consultants, partners and peer-to-peer networks render Bill Cheswick's 1990 network security model of a "crunchy shell around a soft, chewy center" increasingly obsolete. Although inexpensive firewalls are getting smarter and faster, the most significant security issues are on the inside of your network. .

Honeypots are positioned to become a key tool to defend the corporate enterprise from hacker attacks, but some security watchers worry they could bring a new set of security worries with them. Honeypots, which have been around for about 10 years but now are gaining interest and momentum, are digital decoys, of sorts. They are built to be probed and attacked an online come-on to blackhat hackers. Once the honeypot is attacked, security administrators can watch how the hacker moves around the system, and she can see what tools the hacker is using and what information he's going after. It's a way to spy on your enemy. And if you're lucky, it might even be a form of camouflage. Hackers could be fooled into thinking they've accessed a corporate network, when actually they're just banging around in a honeypot -- while the real network remains safe and sound.
