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...

In the big bad world of worms and viruses, the virtually unbreakable Linux Operating System - which gained cult status because of its legendary core stability - is quickly donning the mandatory `Antivirus helmet' to become infallible. The alarming frequency of security attacks has prompted many Antivirus companies to dish out Linux specials, with MicroWorld and F-Secure recently joining the list. Speaking to CXOtoday, P K Kurian, GM - national sales, MicroWorld Software Services, said, "Virus attacks on the Windows platform has literally scared the living daylights off PC Users. This has led to the emergence of GNU/Linux as an alternate solution as it is less vulnerable to virus attacks. MicroWorld is targeting to achieve at least 25% of the total Antivirus and content security solutions market in India of GNU/Linux users in the coming financial year 2004-05" Currently, there is a large Indian user base in terms of GNU/Linux installation on the server side, which include major ISPs, corporate's and SME's who put GNU/Linux on their email gateways for better security, stability and cost considerations. MicroWorld's recently completed the development of its first Linux Antivirus solution, christened MailScan, which is available as a downloadable beta test version from the company's website. Kurian added, "We have currently included a database of more then 86,000 known viruses, worms and Trojans, which are updated daily. Any mails containing the malware will be quarantined immediately and all responsible persons (Admin, sender etc) are notified."

encryptionstreaming mediadigital rightsMPEG-4 Technical Specifications: Rights Management And Security Overview
A streaming-media consortium set a schedule this week for finalizing technical specs for MPEG-4 security and rights management--components that are key to the open standard's adoption among content owners. The Internet Streaming Media Alliance (ISMA)--a global group of companies including Apple Computer, Cisco Systems and Sun Microsystems. . .. A streaming-media consortium set a schedule this week for finalizing technical specs for MPEG-4 security and rights management--components that are key to the open standard's adoption among content owners. The Internet Streaming Media Alliance (ISMA)--a global group of companies including Apple Computer, Cisco Systems and Sun Microsystems --formulated steps to advance MPEG-4 into its final stages. MPEG-4 is a standard for compressing large audio and video files for delivery over digital multimedia platforms including Internet Protocol (IP) networks. It was developed by the Moving Picture Experts Group, the same group that designed MPEG-2 for digital television and MP3 for music files. First, the ISMA will open for review its technical specifications for the encryption and authentication of MPEG-4-compatible files at the National Broadcasters Association annual convention in April. It plans to set the standard by the end of the second quarter. Second, it will introduce a certification program that lets companies obtain an ISMA trademark proving that their products are interoperable with the standard. Finally, it has formed a content advisory board, which will direct the specification for digital rights management, one of the biggest hurdles to clear before content owners freely embrace the emerging standard. Members of the board have yet to be announced, but ISMA president Tom Jacobs said the group has talked with all the major Hollywood studios and the Motion Picture Association of America about the specification. "We have gotten tremendous praise from the industry so far," said Jacobs. "These specs allow for competition in the industry, and we're satisfied andhappy with what is coming along." The Mountain View, Calif.-based nonprofit is pushing for the advancement of MPEG-4 technical standards at a time when proprietary systems are gaining traction among consumer-electronics manufacturers and content owners. The most formidable player, Microsoft, has pushed adoption of its latest multimedia delivery platform, Windows Media 9 Series, on PCs and beyond, recently licensing it for use on non-Windows operating systems. The lack of digital rights management has been the chief stumbling block for open standards and the companies whose products support MPEG-4, including Apple. Paramount to content providers is the ability to protect material from piracy and build a business model around new forms of distribution. And while the industry's tendency is to lean toward support for open standards, illustrated in digital TV's endorsement of MPEG-2, without viable ways to protect content and deliver profits, content owners like on-demand movie rental site Movielink have chosen to work with Microsoft and RealNetworks for their digital-rights management technology. ISMA's technical spec for rights protection would provide keys to the answer. A technical standard for digital rights management "had been the component missing from any MPEG-4 content or individual players," said Ryan Jones, an analyst for The Yankee Group. "The ISMA has been guilty of wandering about because of so many important players with pretty different goals. But having a road map is definitely important, and content security is and should be on the top of the list," Jones said. Microsoft and RealNetworks have gathered support because they have mature products, which consumer-electronics manufacturers are looking for, along with the digital-rights management tools that content owners demand, Jones said. But, he said, Microsoft is notorious for products that are not compatible with earlier versions of software. "These application developers are stuck with two pressures: Consumer-electronicsmanufacturers want format performance and don't care about content security, and on the other end, the content owners want continually improved tools, with rights management," Jones said. Jones added that "the MPEG-4 companies recognize that this space is changing all the time and it's typical of their perspective to get it right. Is it too long? Not if they get the product right. Companies will wait." ISMA, said the group has formed a content advisory board to develop the digital rights spec with input from chief technical officers from a number of content companies. The ISMA spec is based on MPEG-4 IPMP (intellectual property management protections). "We are specifying how you implement interoperable protection measures based on that standard, and that that protection scheme works both for streaming and for download," Jacobs said. ISMA launched in late 2000 in an effort to accelerate the market adoption of open standards for streaming rich media over Internet Protocol. Last year, ISMA released its v 1.0 specification, which defines an end-to-end implementation agreement for streaming ISO-compliant MPEG-4 video and audio over IP. The group signed on last week four new members, Coding Technologies, ContentGuard, Nextreaming Corp. and VBrick Systems. The link for this article located at ZDNet is no longer available. .

The Web server's sole function was to simply deliver a requested Web page, written in HTML, to a client browser. Over time, developers started looking for ways to interact with users by providing dynamic content -- that is, content that displayed a form or executed a script based on user input. Thus Server Side Includes (SSI) and the Common Gateway Interface (CGI) were born. A Server Side Include page is typically an HTML page with embedded command(s) that are executed by the Web server. An SSI page is parsed by the server (a "normal" Web page is not), and if SSI commands are found they are executed before the resultant output is delivered to the requesting client. SSI is used in situations that demand a small amount of dynamic content be inserted in a page, such as a copyright notice or the date. SSI can also be used to call a CGI script; however, there is a performance penalty associated with SSI. The server must parse every page designated as SSI-enabled, which is not an optimal solution on a heavily loaded Web server. The CGI is a standard for communication between a program or script, written in any one of several languages, and a Web server. The CGI specification is very simple: input from a client is passed to the program or script on STDIN (standard input). The program then takes that information, processes it, and returns the result on STDOUT (standard output) to the Web server. The Web server combines this output with the requested page and returns it to the client as HTML. CGI applications do not force the server to parse every requested page; only pages containing CGI-recognized arguments involve further processing.
