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...

network threatsenterprise securitywireless devicesProtecting Enterprises From Mobile Threats: Ensuring Secure Access
Mobile technologies have ushered in sweeping productivity gains at enterprises across the globe. In many cases, they have been central to the creation of the so-called "real-time enterprise." These same technologies, however, have also increased enterprises' exposure to security risks that are frequently underestimated or misunderstood. How significant is the problem?

Mobile technologies have ushered in sweeping productivity gains at enterprises across the globe. In many cases, they have been central to the creation of the so-called "real-time enterprise." These same technologies, however, have also increased enterprises' exposure to security risks that are frequently underestimated or misunderstood. How significant is the problem? According to the U.S. Census Bureau, within three years, 40 per cent of all workers will perform a significant part of their job outside of the office. Research firm IDC shows a similar trend and estimates that two-thirds of the U.S. workforce will be considered mobile by 2006. For today's mobilized, real-time enterprise, it's time to get to work to secure all laptops, handhelds, and wireless devices. Locking down laptops According to the latest edition of the Symantec Internet Security Threat Report, more complex worms and viruses -- known in the security industry as "blended threats" -- are becoming the attack of choice among Internet vandals. Such threats are more sophisticated and often exploit several different flaws to increase the chance of infecting a computer system. The number of attacks that could be classified as a blended threat in the first half of 2003 was 20 percent higher than in the previous six months, according to the report. That's especially disturbing news for employees and partners that regularly travel outside the perimeter firewall and connect to the network. Why? Because blended threats such as Nimda,Code Red, and Slammer specifically target laptops outside the firewall in order to gain unauthorized enterprise network access during an internet connection. (Laptop users can also become unwitting victims of Distributed Denial of Service, or DDoS, attacks.) The link for this article located at ebcvg.com is no longer available. .

A new software tool could allow sensitive data could be pilfered through the air from laptops, mobile phones and handheld computers. An eavesdropper can use the program to identify nearby devices that use the Bluetooth wireless protocol. If the gadget's default security settings mean the device is unprotected, data can easily be stolen. Bluetooth connects devices within a range of 15 metres and is now a standard feature on many devices. Ollie Whitehouse, a UK-based researcher with computer security firm @Stake, created the tool "Red Fang", to highlight the potential dangers of running poorly configured Bluetooth gadgets. He says many people may be unaware that they have Bluetooth installed and that security features are often switched off. "If you're sitting on an intercity train, you're going to have a lot of people around for a long period of time," Whitehouse told New Scientist. "You could try and find their Bluetooth devices and hack into them." The link for this article located at NewScientist is no longer available. .

The U.S. Defense Department's new security policy prohibits its use of wireless devices, such as cell phones and PDAs, for accessing classified data. The new policy is actually an elaboration of a moratorium the Pentagon put in place in July 2001 in order to prevent the exploitation of wireless vulnerabilities. The Secretary of Defense Office has asked the director of the National Security Agency to develop a database of wireless technology vulnerabilities, provide an assessment of the potential risks of specific wireless features and come up with recommendations for countermeasures. The office is also working on a knowledge-management process to help share strategies throughout the department. The link for this article located at News.com is no longer available. .

The Defense Department, concerned that hackers or spies might eavesdrop on classified meetings or secretly track the locations of top U.S. officials, is imposing new limits on its workers' use of the latest generation of wireless devices inside military buildings . The new rules will outline new restrictions on civilian and military employees carrying cellular telephones, pagers and handheld computers while working, even devices that employees bought themselves and carry for their personal convenience at work, said John P. Stenbit, the assistant defense secretary for command, control, communications and intelligence. Stenbit, who also is the Pentagon's chief information officer, disclosed the upcoming rules Tuesday after a technology conference in Washington focusing on security problems of wireless devices. Stenbit said the new rules would be announced within a month. In an earlier speech at the same conference, President Bush's top cyber-security adviser, Richard Clarke, said the technology industry was acting irresponsibly by selling wireless tools such as computer network devices that remain remarkably easy for hackers to attack. The industry's most common data-scrambling technique designed to keep out eavesdroppers, called the wireless encryption protocol, can be broken - usually in less than five minutes - with software available on the Internet. "It is irresponsible to sell a product in a way that can be so easily misused by a customer in a way that jeopardizes their confidential and proprietary and sensitive information," Clarke said. Clarke said government and companies need to explain to consumers ways to keep their information secure over wireless networks. Some recommendations will be included in a forthcomingreport from the administration on cyber-security, which currently runs more than 2,800 pages. Stenbit said the new rules would explain which equipment, such as handheld Blackberry e-mail devices, may be used in different areas of military buildings, including the Pentagon. Stenbit has complained to colleagues about classified meetings being interrupted when electronic bug-sweepers in specially designed conference rooms detect the presence of cell phones and handheld computers.

Wireless devices, including laptop computers and PDAs that are widely used to access company networks, rely on a protocol that has "major security flaws" and are vulnerable to hackers using equipment they can obtain easily, a research group at the University of California at Berkeley has concluded. The culprit is the Wired Equivalent Privacy (WEP) protocol used in the Institute of Electrical and Electronics Engineers (IEEE) 802.11 international standard for wireless LAN communications. It has flaws that "seriously undermine the security claims of the system," leaving it vulnerable to attacks that decrypt traffic, researchers find. The research group intercepted wireless transmissions, modified transmissions, and accessed restricted networks in its examination. The Internet Security, Applications, Authentication and Cryptography (ISAAC) researchers, a group in the university's computer science department, have published their findings. They say they hope IEEE will redesign the protocol, and that companies will design and implement networks with better security principles.
