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 securityprivacy controlsecure networkEnhancing Home Network Security with a Secure Raspberry Pi Router
Designed with an eye on security and privacy, SPR aims to give you complete control — by putting every device on its own private network. . Computer security developer Alex Radocea is looking to bring control of network routers back to the individual, launching a project to create what he calls a "Secure Programmable Router" using a Raspberry Pi 4 single-board computer (SBC). "I started working on this project because I think that Linux provides a tremendous amount of agility and power for secure home networking but I felt like there was no router project out there that pulled it all together," Radocea explains of the SPR Project. "SPR simply enables users to do better than today's status quo. It lets users run a hardened, secure network without restrictive drawbacks. It lets users connect their consumer electronics to the internet with the peace of mind that doing so does not weaken their home network security." .

When I moved into a new neighborhood last week, I expected the usual hassles. Then I found out I'd have to wait more than a month for a DSL line. I started convulsing. If I don't have Net access for even one day, I can't do my job. So, what was I supposed to do? There's an Internet café on the next block, but they close early.

Then I found out I'd have to wait more than a month for a DSL line. I started convulsing. If I don't have Net access for even one day, I can't do my job. So, what was I supposed to do? There's an Internet café on the next block, but they close early. I had no choice--it was time to start sneaking on to my neighbors' home networks. Every techie I know says that you shouldn't use other people's networks without permission. Every techie I know does it anyway. If you're going to steal--no, let's say borrow--your neighbor's Wi-Fi access, you might as well do it right. Step one: Lose the guilt. The FCC told me that they don't know of any federal or state laws that make it illegal to log on to an open network. Using someone's connection to check your e-mail isn't like hacking into their bank account. It's more like you're borrowing a cup of sugar. (Unless you hog their bandwidth by watching lots of streaming video--that's like hijacking a sugar truck.) The link for this article located at Slate is no longer available. .

Agere Systems Inc. is demonstrating at Comdex this week a wireless LAN technology capable of transmitting data at 162 Mbits/second in the 5-GHz frequency band, three times the throughput achieved with an 802.11a device. The technology is targeted at home networking and entertainment as well as enterprise desktop PC applications. . .. Agere Systems Inc. is demonstrating at Comdex this week a wireless LAN technology capable of transmitting data at 162 Mbits/second in the 5-GHz frequency band, three times the throughput achieved with an 802.11a device. The technology is targeted at home networking and entertainment as well as enterprise desktop PC applications . The research is being done by a group of chip and systems companies at the Eindhoven University of Technology in the Netherlands. "We have shown the proof of concept and are working towards delivering silicon chips and systems. A lot more work needs to be done before a commercial system is available," Roman Polz, marketing director for Agere Systems' Client Systems Group in EMEA, told CommsDesign.com. Polz said the group hopes to have a silicon solution ready by 2004. He would not name the project's partners, but said they included other chip makers as well as companies with systems expertise. "We are committed to delivering technological advances that will support data-intensive applications and drive widespread growth in the wireless LAN industry. This demonstration offers a glimpse of the advances Agere is pursuing to fuel the expansion of wireless data beyond e-mail for business users into home applications such as multimedia entertainment," Polz said. Polz said the group believes the technology will be able to compete effectively with wired communications links operating at over 100 Mbits/s, such as Fast Ethernet. Other groups are looking at similar approaches to very fast wireless networking using the 5-GHz range, and Polz added that the IEEE has already started looking at getting such technology standardized within the 802.11 umbrella. Thedemonstration combines multiple input multiple output (MIMO) and orthogonal frequency division multiplexing (OFDM). Together, the two technologies are able to produce a robust wireless data link that can transmit data at more than 162 Mbits/s, depending on the total number of antennas deployed. OFDM technology divides the frequency band into numerous parallel sub-channels to guard against interference, while MIMO transmission significantly increases data rates with several antennas transmitting data streams at 54 Mbits/s and operating in the same frequency. Data is transmitted with three separate transmitter and receiver antennas. The demonstration shows that the growth in data throughput increases proportionally to the number of antennas.

If you have several machines in your home or office network, make the other machines use it. With NAT (or "IP masquerading", as it's called in another universe), multiple machine can be hidden behind one gateway machine. The machines behind the gateway can use their own, private network numbers (usually form the 10/24 or 192.168/16 subnets), and the gateway will translate the private, internal addresses to the public, external address of the gateway machine (hence NAT => Network Address Translation, see Image #3). Any replies made to requests sent out will be translated before sent back to the client. One of the characteristics of this scheme is that a client machine needs to establish a connection, and no outside machine can connect beyond the NAT gateway. From the security point of view this is absolutely desirable. From a practical view, it might be needed to forward single ports to inside machines, e.g. to let them handle WWW or FTP requests.

The first thing I did upon getting cable modem access in my apartment was to get an old Pentium 133 computer, put in two NICs, and fire up the OpenBSD 2.7 boot floppy. I did this for several reasons: first, because I heard that OpenBSD runs as a fast network node even with old hardware; and second, because I knew that it was probably the most secure operating system I can get in that price range. While some people may view OpenBSD security as overkill for a simple home cable modem setup, upon closer examination I found that OpenBSD's secure upon install feature did save my butt more than once; right now, the logfiles show that (literally) not an hour goes by without my system being scanned by someone on the internet.
