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...

Vendors/Productssecurity breach linux
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...

Comcast has begun migrating its customers to a new Internet security mechanism that will help protect them from being inadvertently routed to phony Web pages for pharming attacks, identity theft and other scams.. Comcast is the first major ISP in the United States to adopt the new mechanism, which is known as DNS Security Extensions (DNSSEC). DNSSEC is an emerging Internet standard that prevents hackers from hijacking Web traffic and redirecting it to bogus sites by allowing web sites to verify their domain names and corresponding IP addresses using digital signatures and public-key encryption.

browser securityFirefoxuser securityMozilla's Security Metrics Initiative for Improved Firefox Safety
Mozilla is moving forward on a number of initiatives to ensure that Internet security improves. Among the efforts is a new approach for determining and measuring security metrics. The security metrics effort, announced earlier this year, is designed to figure out what matters in security and then measure and track those metrics. Snyder explained that the first step of the process, now wrapping up, is about determining what the company needs to look at in terms of security metrics. The next step is figuring how to get that information out of bugzilla and capture it on an ongoing basis. After that the challenge is to get information out and generating raw numbers. At the end the company will do analysis on that information to identify trends, correlate factors and draw conclusions.

Simply connecting to the Internet -- and doing nothing else -- exposes your PC to non-stop, automated break-in attempts by intruders looking to take control of your machine surreptitiously. . . . . Simply connecting to the Internet -- and doing nothing else -- exposes your PC to non-stop, automated break-in attempts by intruders looking to take control of your machine surreptitiously. While most break-in tries fail, an unprotected PC can get hijacked within minutes of accessing the Internet. Once hijacked, it is likely to get grouped with other compromised PCs to dispense spam, conduct denial-of-service attacks or carry out identity-theft scams. Those are key findings of a test conducted by USA TODAY and Avantgarde, a San Francisco tech marketing and design firm. The experiment involved monitoring six "honeypot" computers for two weeks -- set up to see what kind of malicious traffic they would attract. Once breached, the test computers were shut down before they could be used to attack other PCs. The link for this article located at Byron Acohido and Jon Swartz is no longer available. .

Firewalls play a crucial role in network and computer security. Part I of this series, Home User Security: Your First Defense, examined the typical functions of firewalls and how they can be of use on an individual level. More specifically, the need for personal firewalls in the home office was discussed. Now we will explore some of the best options on the market, many of which are available free of charge or are already installed on major operating systems. The average user has several programs that regularly access the Internet (whether he or she knows it or not), some virus problems, and an interest in a cheap or free solution with minimal configuration and maintenance headaches. Advanced options like encryption, ad-blocking, cookie digestion and hiding offer greater privacy, but often entail more work on the user's part. There are trade-offs, as always, but most firewall packages provide simple enough interfaces that anyone can monitor the firewall's activities. Firewalls are no longer the sole responsibility of senior network administrators -- we are all qualified operators. Inbound filtering refers to any incoming data. This is what most people equate to the work of a firewall. However, outbound filtering can be just as important, if not more important to the security of a system. For example, after installing a firewall like Zone Alarm for the first time, many a user will notice strange programs trying to access the Internet using unusual ports. These could be malware that nestled into the system through a variety of means. Many people are unaware that they already have such malware installed, and possibly have for some time. In the worst case this could cause their computer to act as a "zombie" or "drone" under the control of a third party elsewhere onthe Internet. As this type of malware is often not discovered by anti-virus software, the purpose of outbound filtering is to detect these programs and prevent them from doing harm to others. In addition, outbound filtering will notify a user of other attempts to access the Internet such as by spybots and spyware, and thus prevent the leaking of your personal information into the ether.

Firewalls are the cornerstone of Internet security, and for small businesses that might not have in-house security expertise, shopping for one can be difficult. But without a firewall, no one in an organization should be accessing the Internet. How do small business owners choose from the wide array of products, functionality and firewall types available in today's market? Fortunately, most firewalls from mainstream vendors do the job as advertised, but some small office home office (SOHO) firewalls are not suited for organizations with complex security needs like virtual private networking (VPN), and the differences are not always clear. In addition, there are just some functions that firewalls cannot perform reliably yet. . In the digital era, securing your business's online presence is crucial.

Even large companies are often glad to offload this burdensome task. Engaging a service can provide a very high level of expertise focused on this important area for an affordable cost, and it can relieve the enterprise of the complex and thankless job of spam control. Fighting spam takes focused attention and breadth of view. You can't tell by looking at a message whether the tale it tells or the offer it tenders is legitimate or specious. Services that deal with literally millions of messages daily have an opportunity to see the behavior of a spammer, to see how many copies of a message were sent, where they were posted, and whether their origin and their "Sender" field match.
