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...

ipv6networking basicsinternet protocolIPv6 Tunnels: Transitioning from IPv4 to IPv6 Addressing
More Internet traffic is expected to be carried via tunnels as the Internet infrastructure migrates from IPv4, the current version of the Internet protocol, to the long-anticipated upgrade known as IPv6.. IPv4 uses 32-bit addresses and can support 4.3 billion devices connected directly to the Internet. IPv6, on the other hand, uses 128-bit addresses and supports a virtually unlimited number of devices -- 2 to the 128th power. The regional Internet registries said in April 2010 that less than 8% of IPv4 addresses remain unallocated. The remaining IPv4 addresses are expected to run out in 2011 or 2012.

IPv6 is the next-generation Internet protocol designed by the IETF as a replacement for IPv4. Most of today's Internet uses IPv4, which has been remarkably resilient in spite of its age; however, it is beginning to have problems in various features areas. Its most visible shortcoming is the growing shortage of IPv4 addresses needed by all the new devices connecting to the Internet. Other limitations are in such areas as QoS, security, autoconfiguration, and mobility. As a result, the IETF defined IPv6 to fix the problems in IPv4, and added many enhancements to cater the future Internet. This article addresses the problems in IPv4 that lead to the design of IPv6, presenting the IPv6 design philosophies and IPv6 features, as well as a technical tutorial to enable IPv6 support on your Linux machines.

The next version of the Internet Protocol, which provides a 128-bit standard to transmit data, is getting a jump-start for adoption with its endorsement by the Department of Defense. The result: A boost in the number of available Internet addresses, to eventually number as many as an address for every cell in every person on the planet. The DOD is requiring all contractors involved in its Global Information Grid program to support the new Internet Protocol version 6 as of October 1, 2003. IPv6 is expected to replace the current 32-bit IP version 4 (IPv4) for nearly all Internet traffic by 2008. The replacement is necessary because the number of available of IP addresses is dwindling, say the standard's developers. The Internet Engineering Task Force has warned since the mid-1990s that we're running out of available Internet addresses. Already, 170 billion of the 250 billion Internet nodes available under IPv4 are in use, says Latif Ladid, IPv6 Forum president. The link for this article located at PCWorld is no longer available. .

privacy technologypeer-to-peeranonymityEnhancing Anonymity with Six/Four Protocol in Online Communication

A group of veteran hackers is about to unveil a new peer-to-peer protocol that may eventually let millions more surf, chat and e-mail free. . .. Peer-to-peer networks such as Morpheus and Audiogalaxy have enabled millions to trade music, movies and software freely. A group of veteran hackers is about to unveil a new peer-to-peer protocol that may eventually let millions more surf, chat and e-mail free from prying eyes. Hacktivismo, a politically minded offshoot of the long-running hacker collective Cult of the Dead Cow, will announce the protocol -- called "Six/Four," after the June 4, 1989 massacre in Beijing's Tiananmen Square -- in a presentation Saturday at the H2K2 hacker conference in New York City. The group will publish the Six/Four code on its website in early August to coincide with Las Vegas' DefCon security confab. Six/Four combines peer-to-peer technologies with virtual private networking and the "open proxy" method for masking online identities to provide ultra-anonymous Internet access. Virtual private networks, also known as "tunnels," allow one computer to establish direct, secure communications with another over the Internet. Banks and government agencies use these VPNs all the time for money transfers and talks that they want kept quiet. Traditional VPNs take the information along a single path from Point A to Point B. Six/Four's route is more circuitous, sending its tunnel through a series of computers on its peer-to-peer network before heading to the public Internet. Data goes from Point A to Point K to Point Z to Point G, only eventually winding up at Point B. "It's like a highway that's redesigned for every Brinks truck that rides on it," said Oxblood Ruffin, Hacktivismo's founder. Once this roller-coaster ride is over -- the end point is called a "trusted peer" in the Six/Four scheme -- the information then makes its way to the Web pages, chat sessionsand file servers of the open Internet. Currently, hackers and other privacy-minded folk go through "open proxies" -- misconfigured corporate servers -- to mask their identities before chatting or visiting Web pages. It's a little like snail-mailing a letter from a post office box in another state. "Theoretically, for every server in between you and the destination server, another search warrant is required to view that computer's logs, if they still exist, to get your IP (Internet Protocol) address," said a former dot-com technology executive who's now an open-proxy devotee. Six/Four takes this about 100 steps further by adding layer after layer of additional anonymity, because "each link in the chain only knows the link immediately before, not the final destination," said "The Mixter," the 23-year-old German hacker who authored Six/Four.

In my line of work it is inevitable, but always shocking, to see the number of high-risk security flaws developers have left behind. Most worryingly, a major proportion of vulnerabilities are due to a basic misunderstanding of the internet protocol and system software used to host or use the web application. Many developers fail to understand the nuances of the HTTP protocol and assume that it is too difficult, or not worth the trouble, for an attacker to assault their custom application. Developers must assume that every packet of data not coming from the organisation's hosts and servers can be modified. Infrequently, 'security aware' sites manage to correctly implement input validation rules for client data. Unfortunately, all client-side checking and data validation processes can be bypassed by an attacker using commonly available tools and methodologies.
