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...

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...

Linux administrationsecurity architectureinformation systemsNew Linux Security Course Launches at Durham Technical Community College
A core component of any curriculum in modern information security is the security of the operating systems that reside on the workstations and servers of a network. Effective information security depends on addressing all facets of how information is stored, moved, and modified. Since the operating system of a computer is the primary means of implementing the security of the information on that computer, it must be configured to minimize the risks of losing or compromising the data being processed. . Durham Technical Community College, as part of its new Information Systems Security curriculum, is developing a security course based on securing operating systems. This course will instruct students in the fundamentals of designing security architectures and provide an overview of security administration of several operating systems, focusing primarily on Windows and Linux. Additionally, students will also learn the design of basic security defenses and the use of network analysis tools. Topics covered will be essential foundation for later courses which will cover intrusion detection, Defense-in-Depth, attack methodologies, and firewall security and configuration.

"If you can't afford the security, you can't afford the project," says Rosaleen Citron, CEO of Toronto-based security firm WhiteHat Inc., citing a well-known axiom in the information security industry. On the other hand, "most businesses, big or small, can't afford to defend everything," says Mary Kirwan, an independent security expert in Toronto. Indeed, they would impede their productive business activity if they tried. . . .. Companies, like the humans who make them run, are creatures of habit. Some of those habits can make information systems more secure, rather than less. There's no such thing as absolute security, of course. But the seven best practices of highly secure companies are a standard against which CEOs can measure their organizations. "If you can't afford the security, you can't afford the project," says Rosaleen Citron, CEO of Toronto-based security firm WhiteHat Inc., citing a well-known axiom in the information security industry. On the other hand, "most businesses, big or small, can't afford to defend everything," says Mary Kirwan, an independent security expert in Toronto. Indeed, they would impede their productive business activity if they tried. An effective approach to information security involves making choices. Companies must compromise, deciding what are the most important assets that need to be protected and then deploying a proportionate level of security around them. 1. Assess and audit Have a risk assessment and a regular security audit performed by an outside pair of eyes. The risk assessment creates an inventory of assets and undertakes a detailed threat assessment. It assigns ratings to threats, and proposes a list of counter-measures. The security audit is designed to show whether those measures have been adequately implemented. How "regular" a security audit should be depends on the business and how much information is being exchanged with customers and suppliers.

"Network and information security has become increasingly important with growing usage of the Internet and other information and communication technologies. In today's society, much depends on networks and information systems. Additional requirements for security will rapidly increase as networking and computing develop further and electronic communications become part of all aspects of our daily lives. For instance broadband connections offer people the possibility to be "always on". This, of course, increases the vulnerability of systems and multiplies the probability of some sort of cyber-attack. Enhanced security is therefore a key element for the success of broadband. New wireless applications will enable people to access the Internet from anywhere. The tendency to connect to the Internet everything from printers to central heating systems will continue. Just as people expand the ways they use the Internet, so the potential security risks multiply. The link for this article located at PublicTechnology.net is no longer available. .

A House panel last week gave two-thirds of all federal agencies a failing grade for efforts to secure information systems -- a worse showing than last year attributed to greater awareness of security vulnerabilities. Rep. Stephen Horn (R-Calif.), who has graded agencies on several information technology management topics over the years, gave the government an overall grade of F for its effort to secure IT systems, with 16 of 24 agencies surveyed receiving the failing grade. Only one agency received a grade higher than a C-plus. "It is a disappointing feeling to announce that the executive branch of the federal government has received a failing grade for its computer security efforts," said Horn, chairman of the House Government Reform Committee's Government Efficiency, Financial Management and Intergovernmental Relations Subcommittee, at the Nov. 9 hearing during which he released the grades. The grades are disappointing, even if they help wake up agency managers to the fact that there's a lot of work to be done to secure the systems, said Sallie McDonald, assistant commissioner for information assurance and critical infrastructure protection at the General Services Administration.

Lately, reactions to non-intrusive probes and network activity that is merely unexpected are becoming increasingly hostile; a result from increasing amounts of incidents and security threats. From my perspective of security, overreactions to activities not crossing authorization and legal boundaries, are leading to a scenario where anyone acquiring basic information about a system needs to be afraid about potential consequences. Seen under a wide scope, this leads to network security no longer being transparent. Why a non-transparent security situation on the Internet is bad? Obviously, it is a big advantage to malicious intruders who have no legal concerns because they can conceal their identity through compromised systems, and a big disadvantage to security firms, admins and individuals who depend on a complete picture of Internet security problems to solve them. Non-malicious, beneficial large scale scans like the broadcast amplifier scanning projects are becoming harder and riskier to perform using legal resources.
