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...

Messaging security vendor CipherTrust Inc. on Monday released a new component of its IronMail appliances designed to stop spam messages before they get to customers' networks. Known as Connection Control, the technology relies on the company's Spam Profiler system to identify the IP addresses of the most egregious e-mail abusers. It does this through the use of a scoring index that assigns incoming messages a score of zero to 100, based on the likelihood that they're spam.

Users of the open-source mail package should now be able to reduce their spam levels.

Sendmail on Monday released the first implementation of a mail filter that uses Sender ID, an anti-spam technology currently being considered by the Internet Engineering Task Force (IETF). Sender ID is a combination of the earlier Sender Policy Framework (SPF), invented by Meng Wong of pobox.com, and Microsoft's Caller ID proposal. The system aims to reducing the quantity of spam emails sent across the Internet by checking who they claim to be from. The plug-in mail filter, or "milter" in Sendmail jargon, works with the open source and commercial versions of Sendmail, but is still considered pre-release software at this stage. "Sendmail's Sender ID milter is a major weapon in the war on spam," said Meng Wong in a statement. "Now, system administrators everywhere can evaluate this promising new technology themselves and easily adapt it to their needs," Wong added. Sender ID uses records in the Domain Name System (DNS) to authenticate the sender of an email message. Most spam and messages sent by viruses use spoofed sender email addresses, making it more difficult to trace where they're sent from. With Sender ID, you can tell which messages come from forged addresses and reject them, often before the message body is sent. While this won't stop spam entirely, it will make life more difficult for mass-mailers, and as part of a series of measures may see our inboxes get less junk mail.

E-mail accreditation isn't taken all that seriously as a method of spam control. I'm baffled as to why. It appears to be an effective means of helping ensure that spam filters don't accidently block e-mail that the recipient actually wants to get. These legitimate messages wrongly blocked by spam and virus filters are known as "false positives," and they're as big a problem as spam itself. E-mail marketers and bulk mailers - like us here at Security Pipeline - are putting up the loudest squawk about the problem. I've seen estimates that 10-15 percent of legitimate bulk mail fails to reach its recipients, because messages are blocked by overzealous spam and virus filters. That includes the very newsletter you're reading now; industry statistics tell me that one subscriber in seven or eight will simply not receive this message. (Let me know if you're not reading this. Ha ha. I make ze joke, yes?) We e-mail publishers are looking to improve the delivery rate, and e-mail accreditation has emerged as one technique. The idea is this: Companies like Bonded Sender and Habeas, Inc., sign up bulk e-mailers to agree to terms of service designed to keep e-mailers from sending spam. (Some anti-spam advocates say the terms of service aren't strict enough, but at least the accreditation programs are trying to put SOME controls in place.) The e-mail publishers pay to use the service. (This is a bit down the page, but worth reading) The link for this article located at securitypipeline.com is no longer available. .

On Nov. 22, the U.S. House of Representatives voted 392 to 5 to pass the Can Spam Act of 2003, which is designed to put controls on the distribution of spam. For once, the House and Senate saw eye to eye, more or less: The House version is an only slightly modified version of the Can Spam Act (S.877) passed by the Senate in October, and it's expected to be signed by the president early next year. But the word can may be interpreted in two ways--obliterate spam, or allow it. And that pretty much sums up how the legislation can be interpreted. It puts some limitations on unsolicited commercial e-mail, but it doesn't disallow spam completely. It allows for creation of a Do Not Spam Registry, equivalent to the successful Do Not Call Registry, but it trumps stronger laws that have been passed by state legislatures--California's spam law, for example, has an opt-in requirement and gives individuals the right to sue spammers.

Legislation to ban or limit spam is proliferating almost as rapidly as the e-mails that promise to provide a slim, wealthy, well-endowed, sexually satisfied life. But antispam advocates disagree over whether legislation such as the recently passed United Kingdom and California antispam laws will slow the flood of spam, due to loopholes that could be easily exploited by bulk e-mailers. Advocates and legal experts also warn that any local law will have, at best, a limited effect, and are calling for a consistent, comprehensive global ban on spam. "Overall we need a combination of new laws to let spam recipients and Internet service providers sue spammers to change the economics of spam, and modest technical improvements to Internet mail to make it easier to establish where a message really came from," said John Levine, a board member of the Coalition Against Unsolicited Commercial E-Mail.

Once thoroughly bipartisan, the debate in Washington over how to reduce the flow of bulk e-mail is now pitting Democrats against Republicans--a development that threatens to complicate enactment of laws regulating spam. Politicians on Capitol Hill have realized that their constituents are fed up with the ever-increasing deluge of unsolicited e-mail, and most legislators appear to favor Congress taking some sort of action. But disagreements about what action is wisest have erupted along traditional political fault lines that pit Republican values against those cherished by Democrats. On Wednesday, bickering erupted during a meeting of two House Energy and Commerce subcommittees over which of two bills--one backed largely by Democrats and one supported almost entirely by Republicans--would do a better job of reducing spam and punishing spammers. "This committee is moving in the wrong direction," said Rep. Bart Stupak, a Michigan Democrat who is one of the sponsors of his party's Anti-Spam Act, better known as the Wilson-Green bill. Twenty of the bill's sponsors are Republicans, while 33 are Democrats. .
