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...

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...

public sectorconferenceprivate sectorDef Con Conference Shifts Focus To Critical Cybersecurity Dialogues
When Jeff Moss founded the Def Con hackers convention in 1993, he never imagined that two decades on, one of the key speakers at the annual Las Vegas event would be four-star General Keith Alexander, head of the U.S. National Security Agency. . Once known as an excuse for computer geeks and social misfits to drink cheap beer, create mischief and party all night Sin City-style, Def Con has transformed itself into a venue where elite and amateur hackers alike debate serious security issues with experts from the public and private sectors.

cybersecuritygovernmentthreatsJeff Moss Insights: Cybersecurity, Government Roles And Threat Landscape
As a hacker and organizer of Defcon, at event at which computer security vulnerabilities and exploits are routinely unveiled, Jeff Moss seemed an unusual choice when he was named to the Homeland Security Advisory Council in June.. But his background and lack of government experience brings a fresh, outsider's perspective to a public sector plagued by a fast-changing threat landscape, perpetual turf wars, and bureaucratic inertia. With National Cyber Security Awareness Month under way, CNET News discussed with Moss his new role, his thoughts on the national ID card debate, and how the government wants to use social media sites for public emergency alerts. This edited interview is the first of two parts. Part two will run on Monday. The link for this article located at CNET is no longer available. .

public sectorcontract scrutinycybersecurity chiefCybersecurity Chief Purdy Resigns Following Contract Scrutiny
The Bush administration's cybersecurity chief, who worked under an unusual agreement with a private university that does extensive business with the office he manages, is leaving his job. Donald ``Andy'' Purdy Jr. will step down as acting director of the National Cyber Security Division, part of the Department of Homeland Security. A government spokesman, Jarrod Agen, declined to comment on Purdy's plans, but colleagues circulated an invitation to his farewell party next week. Purdy worked at Homeland Security under a two-year contract with Carnegie Mellon University that expires Oct. 3. Under the contract, the government paid Purdy $245,481 in salary and benefits each year, not including travel reimbursements; Carnegie Mellon paid him an additional $43,320 a year. . His contract drew congressional scrutiny after The Associated Press reported in June that Purdy's cybersecurity division has paid Carnegie Mellon $19 million in contracts this year, almost one-fifth the unit's total budget. Purdy, who controlled a budget of about $107 million and as many as 44 full-time federal employees, said at the time he was not involved in discussions over his own office's business deals with the school.

Security deperimeterisation is at the heart of plans that underpin the Cabinet Office's high-profile transformational government programme, delegates at the Infosecurity Conference will be told today. Increasing demands for public sector bodies to exchange information and share IT services will mean that traditional approaches to security will no longer be appropriate, the Cabinet Office's security adviser will say. Steve Marsh, director of the Central Sponsor for Information Assurance, said that a new security architecture would play a key role in the transformational government plan. . .

identity managementauthenticationpublic sectorEnhancing Public Access with Federated Identity in e-Government
Leading public sector IT bosses have told silicon.com they would welcome moves by the UK government to adopt federated identity in order to provide the public with faster, more efficient access to online services. But one expert believes the government has been too preoccupied with the controversial ID cards project to consider such as solution. . Federation would essentially mean government departments would share the public's identities across their systems and authenticate against one another. This would speed the process of signing in and using multiple online services and would eliminate layers of administration. Richard Steel, head of ICT at London Borough of Newham, gave such a system a ringing endorsement. "I see it as the way forward," he told silicon.com. The link for this article located at silicon.com is no longer available. . The collaboration would optimize service delivery by facilitating information sharing among agencies, improving citizen engagement..

cost reductionpublic sectoropen source initiativeUnveiling the Government Open Code Initiative: Transforming Public Software
As we celebrate the holiday season and prepare for the next round of legislation, a group of state and local governments has banded together to collect and distribute freely the costly software that normally runs taxpayers $100 billion annually. Called the Government Open Code Collaborative or GOCC.gov, this organization states that its members work together voluntarily to encourage "the sharing, at no cost, of computer code developed for and by government entities where the redistribution of this code is allowed". . In addition to state and local governments, the organization also encourages collaboration between public sector entities and non-profit academic institutions. With Web facilities hosted by the University of Rhode Island, GOCC.gov has a repository dedicated to hosting open-source software for download by any state or local government. As so many people have said, "Nothing is as powerful as an idea whose time has come." And GOCC.gov is an idea whose time is long overdue. Open-source advocates attempting to initiate legislation and fight the battles on the floors of the various Houses, only to discover the political might and opposition of Microsoft, now have an alternative. State agencies now can download software for free and use it to create a cohesive and standard government infrastructure..

This is the last article in a four-part series looking at U.S. information security laws and the way those laws affect the work of security professionals. This installment continues the discussion of information security in the public sector and provides an overview of national security law in the United States as it pertains to information security. It is easy to think of "national security" as meaning the security provided by military and intelligence gathering capabilities, and in certain specific legal contexts, that specific definition is both accurate and complete [1]. But as the threat of terrorism became clear, even before the attacks of September 11, 2001 national security came to mean, in additional to national defense, the protection of the public and private sector facilities essential to delivering the goods and services that maintain the quality of life in the United States, or as officially defined, the nation's "critical infrastructure." [2] Executive Order No. 13231 [3] , entitled, Critical Infrastructure Protection in the Information Age, issued by the President five weeks after the September 11, 2001 attacks, addressed itself to the information technology systems that form part of the nations' critical infrastructure. The Executive Order noted that information technology had "changed the way business is transacted, government operates, and national defense is conducted. Those three functions now depend on an interdependent network of critical information infrastructures." The order went on to authorize "continuous efforts to secure information systems for critical infrastructure." As we begin the discussion of the law in this area, it is useful to understand that the information technology we are talking about operates in threegeneral arenas: (1) the business environment, (2) the environment for the delivery of government services, and (3) national defense.
