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...

Security vendor Websense if offering Facebook users and businesses a new free . This also draws from data gathered by US ISP Radialpoint and URL shortening service bit.ly before performing further heuristic analysis as a final check. If a bad post is detected, the system logs and informs the user who makes the final decision. As with the original Defensio system - acquired a year ago when Websense bought the company of the same name - it can also monitor web pages for rogue posting, pre-emptively blocking those it deems unwanted. "We are seeing real threats to Facebook such as Koobface," said Websense senior research manager, Carl Leonard. According to Leonard, an advantage of Web 2.0 monitoring was that it gave security companies a way of following criminals inside the otherwise closed world of social media, something that many security vendors can't yet do. "We can have visibility into threats on these social networks, and have a fantastic feed of information that can benefit all our customers," he said.

security practicesserver securityiptablesEffective Iptables For Securing Linux Servers Against Spam Attacks
'Spamming', when used in a different context, does not necessarily have to be email specific. If you ever had a chance to play arcade fighter's such as Street Fighter 2, you'll notice that certain fighters have "cheap" moves that can be "used over and over", such as M. Bison's scissor kick corner trap (ah the old days). A player could pretty much "spam" this combo over and over. The interesting part about this cheap combo is that it could be countered just as easily with some skill. A basic set of good iptables rules is the perfect counter punch to a slew of common spamming attacks - no need to have SpamAssassin or procmail process the email when it doesn't even get through the front lines! Read on to gain a good base understanding of iptables and its rules. Ha-dou-ken! . The link for this article located at SearchEnterpriseLinux.com is no longer available. .

I run a Postfix-based mail server that services a few hundred users with an average load of a couple of thousand legitimate messages a day -- but thanks to spam, the actual load on the server is much higher. I use Realtime Blackhole Lists (RBL) and Distributed Checksum Clearinghouse (DCC) clients on Postfix and SpamAssassin to reduce the impact of spam. . RBLs are lists of IP addresses of known and potential spam originators. There are many RBL providers, such as Spamhaus, Spamcop, and DNSRBL. These lists are also known by various other names, such as blacklists or blocking lists. Mail servers can connect to RBL servers to check on IP addresses.

social engineeringweb securityinternet threatsCombating Social Engineering Risks with SiteAdvisor's Innovative Solutions
SiteAdvisor was founded by a group of MIT engineers who realized there was a gaping hole in existing Web security products. While traditional security companies had gotten relatively good at addressing technical threats like viruses, they were failing to prevent a new breed of "social engineering" tricks -- scams that trick users into downloading malicious software or signing up at Web sites that send unwanted e-mail or steal personal information. . SiteAdvisor’s approach comes at a time when computer threats are shifting from technical attacks like viruses to economically motivated attacks like adware, spam, and phishing. An estimated 61% of all computers are infected with at least one piece of adware or spyware, according to The National Cyber Security Alliance and America Online (12/05). Jupiter Research (2/06) reports that the average consumer received 3,253 pieces of spam in 2005. “Phishing.
