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...

The essence of most people’s regard for cybersecurity: we’re DOOMED. . That’s one of the key takeaways from the UK’s National Cyber Security Centre (NCSC), which released the results of its first ever UK cyber survey on Sunday, along with a list of the most craptacular passwords found most often in breached databases.

cyber threatslog monitoringincident detectionUnderstanding Log Monitoring For Cyber Threats And Breach Prevention
Two weeks ago, I essentially claimed that nearly every company I know is hacked -- and in many cases, thoroughly hacked. Although there's a bit of hyperbole in that statement, it isn't that far from reality. That statement, however, has led some readers to believe detecting hackers and preventing attacks is impossible. Nothing could be further from the truth.. Discovering malicious hackers Despite what the movies show, hackers are never good enough to go unnoticed. Even the professionals hackers who are making millions of dollars really don't do much to stay hidden. They don't need to: Most admins aren't looking. The Verizon 2008 Data Breach Investigations Report [PDF], which is quickly becoming one of the most respected sources on computer crime statistics, said it best: "Evidence of events leading up to 82 percent of data breaches was available to the organization prior to actual compromise. Regardless of the particular type of event monitoring in use, the result was the same: Information regarding the attack was neither noticed nor acted upon." Your No. 1 tool for detecting malicious activities is your log files. Most admins don't turn them on, and those who do usually don't monitor them. Additionally, many companies only turn on logging on their servers, even though most of the malicious break-ins occur on their user's workstations.

What is the secret to network security? In the wake of recent high-profile security breaches like at LexisNexis and MasterCard, it's worth asking what it takes to nail down network security --- and what are the secrets not everyone knows? . "There's not really a secret," says Marcus Shields, enterprise product manager at Soltrus, Inc., a Canadian firm specializing in digital trust services. "There are a lot of things that organizations should be doing but aren't. A lot of it comes down to common sense." The problem with common sense, it has been observed, is that it is not very common. Consequently, some of the basic precautions that any organization can take to secure its network might as well be arcane secrets of the security trade -- at least until you take them and make them a part of day-to-day procedure.

A two billion dollar corporation headquartered in Massachusetts was recently hit by the SQL Server Slammer worm. It took down a key corporate database server for several days. Even though information about the vulnerability and the patch itself have been available since January 2003, the company had not upgraded its system and was, as a result, compromised. How did that happen? What can a computer manager to do to prevent something like this in the future? A major ISP has been having problems with its customers' anti-spam filters because they are set too high and too much legitimate mail is being bounced. A couple of months ago the company had a major reduction in force, and they eliminated the department responsible for maintaining the filter software, which means it might be a very long time before the filters will be fixed. What can a computer manager do when this happens? Your company CEO has been reading the trade press again. How can you tell? He has just told you that you need to beef up all of the company's computer security. Oh, and by the way, your budget is being squeezed once more, which means that you'll have to do it without any additional money, again. Sigh. Is there anything you can do to address the security concerns while not blowing the precious IT budget? The link for this article located at Crossnodes is no longer available. .

Contrary to popular belief, corporate sabotage is among the least likely causes of computer security breaches. According to an April 2002 survey by the Computer Security Institute, sabotage accounted for just 8 percent of system attacks in 2002. Security breaches are more often due to errors by end users or administrators. The inadvertent gaffes are the main culprits for introducing viruses, allowing denial of service attacks, and opening entryways to supposedly secured data. CIOs can reduce, and possibly eliminate, an organization's risk from these errors by creating and implementing a comprehensive set of IT security policies aimed at user behavior. These policies, along with efforts to educate users about how to eliminate security weaknesses, can thwart future vulnerabilities and boost awareness about security issues throughout the enterprise. Defining IT security policies and making them operational is no light task, according to TechRepublic members. A good security policy must address both end users and administrators. On the user side, policies should address how the staff is allowed to make use of computer equipment and applications, according to TechRepublic member William Graham, president of G&G Computing consultancy in Fort Campbell, KY. Graham recommends that end-user policies include the following: The link for this article located at ZDNet is no longer available. .
