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...

security featuresprivacyinternet accessExploring Privacy Versus Security in Home Wireless Networks
"I opened up my wireless home network to the world, and I've never felt more comfortable." Thus starts a startlingly different perspective on privacy and security. . . .. Last week, I turned off all the security features of my wireless router. I removed WEP encryption, disabled MAC address filtering and made sure the SSID was being broadcast loud and clear. Now, anyone with a wireless card and a sniffer who happens by can use my connection to access the Internet. And with DHCP logging turned off, there's really no way to know who's using it. What's wrong with me? Haven't I heard about how malicious wardrivers can use my connection from across the street to stage their hacking operations? How my neighbors can steal my bandwidth so they don't have to pay for their own? How I'm exposing my home network to attacks from the inside? Yup. So why am I doing this? In a word, privacy. By making my Internet connection available to any and all who happen upon it, I have no way to be certain what kinds of songs, movies and pictures will be downloaded by other people using my IP address. And more important, my ISP has no way to be certain if it's me. In mid-April, Comcast sent letters to some of its subscribers claiming that their IP addresses had been used to download copyrighted movies. Since Comcast is not likely to improve customer satisfaction and retention with this strategy, it's probable the letter was a result of pressure from the Motion Picture Association of America or one of its members. And to Comcast's credit, it stopped short of direct accusation; instead it gives users an out. Says the letter, "If you believe in good faith that the allegedly infringing works have been removed or blocked by mistake or misidentification, then you may send a counter notification to Comcast." That's good enough for me. I've already composed my reply in case I receive one of these letters someday. "Dear Comcast, I am so sorry. I had no idea that copyrighted works were being downloaded via my IP address; I have a wireless router athome and it's possible that someone may have been using my connection at the time. I will do my best to secure this notoriously vulnerable technology, but I can make no guarantee that hackers will not exploit my network in the future."

network securityremote accessinternet threatsRisks of Wireless Networks: Urban Data Theft and Hacking Threats
I recently strolled past federal buildings along Connecticut Avenue in Washington, carrying a beta-test model of a tablet PC equipped with an integrated IEEE 802.11b wireless PC Card. In no time, it auto-detected a wireless network. The tablet asked me if I wanted to connect. I declined, but as I kept walking, the tablet detected signals for three more wireless networks. . .. I recently strolled past federal buildings along Connecticut Avenue in Washington, carrying a beta-test model of a tablet PC equipped with an integrated IEEE 802.11b wireless PC Card. In no time, it auto-detected a wireless network. The tablet asked me if I wanted to connect. I declined, but as I kept walking, the tablet detected signals for three more wireless networks . (Apparently, the Secret Service is curious about these free-ranging signals, too, and has sent teams around Washington snooping for wireless networks that broadcast signals onto the street.) I did no probing, so I don't know whether the signals my tablet PC detected came from government, corporate or home networks. Nevertheless, they're out there, just waiting for someone to exploit them. If a wireless connection extends beyond a network's firewall, or if no firewall exists, any passerby with a wireless notebook PC can tap the network's resources. Even if the network is protected, the passerby might manage to get Internet access. Say, for example, that the wireless network assigns the intruder a numerical Internet address, as many wireless networks routinely do. That makes a great starting point for hacking. The numerical, or Internet protocol, address lets the intruder guess at the range of IP addresses, which could lead to probing and denial-of-service attacks. Furthermore, passersby who have modern operating systems such as Microsoft's Windows XP can learn the names of the network servers. The GCN Lab found this out during a recent review of XP Service Pack 1. We couldn't connect to the servers, but we could see them. More insidious is stealthy monitoringof wireless networks from outside a building. Even if the network requires its users to have specific Media Access Control addresses in their hardware, a hacker can pretty easily sniff out such information from a bus stop or park nearby because MAC addresses are transmitted in plain text. By faking a sender's address, a hacker could break in as surely as if sitting at a desk inside the building. There are two main dangers to unsecured wireless networking. The first is that an intruder could use information from the wireless connection to steal data or launch an attack on the computing infrastructure. The second is that an intruder could use the connection for free Internet access. Hackers, and presumably terrorists, know that anonymous e-mail from services such as Hotmail and Yahoo can be traced backward. That's because information about an organization's IP address, operating system and files travels along with the e-mail headers. Say a terrorist stands outside your office's headquarters and e-mails threats over your wireless network. The digital trail will lead back to your office. And if the terrorist stole a notebook PC to do the deed and gets rid of it afterward, the unsuspecting network administrator will be the one left holding the bag. To add to the threat, more and more people support the "free Internet" movement in their neighborhoods. Some are "war-chalking," making chalk marks on buildings to signal others what sort of free wireless access can be tapped there, similar to the hobo symbols of old. I didn't happen to notice any chalk marks as I walked down Connecticut Avenue, but with wireless signals on the street silently screaming for clients, it's only a matter of time.

"We never gave security a thought," Brian Chee says, talking about what was probably the world's first wireless data network. Chee worked on Aloha Net, a new concept in communications developed by the University of Hawaii back in the late 60's. This network, using a form of magic called "carrier sense multiple access," let the university link computers on each of the state's islands. Later, the technology would migrate to the wired world, and with some improvements, would be known by the name "Ethernet." The data carried by Aloha Net eventually went to undersea cables and microwaves, Chee went on to run the university's prestigious Advanced Network Computing Laboratory, and wireless networking went on to ignore security. In fact, wireless networking ignored security for so long that most people think it still doesn't have any. In many cases, they're right. But it doesn't need to be that way. Now that wireless communications is becoming a critical technology for the enterprise, it can't be that way. The problem is that the disconnect between the IT staff's memories of wireless networking and today's reality is sufficiently large--a factor that keeps the technology from growing as fast as it should.
