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...

Vendors/Productssecurity breach linux
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...

security advisorycritical flawauthentication bypassNTP Authentication Bypass Threat: Critical Flaws Impact Network Security
Network admins take note: A set of vulnerabilities can bypass HTPPS with ease and result in spying, outages and authentication bypass. . Discovered on Wednesday by Cisco's security intelligence and research group Talos, the critical bugs are found within the Network Time Protocol (NTP), designed to synchronize the clocks of computers over a network. Developed before 1985, the protocol is one of the oldest still in use. In a blog post documenting the find, Talos said a logic error within the Network Time Protocol daemon (NTPD), the operating system behind the protocol, could allow attackers to bypass authentication procedures and effectively grant them the keys to a network kingdom. . Significant vulnerabilities in TOTP enable malicious users to circumvent validation, resulting in potential threats and operational turmoil..

The USENIX Security conference has been warned that by tweaking the firmware on certain kinds of phones, a hacker could make it so other phones in the area are unable to receive incoming calls or SMS messages.. The hacker modifies the baseband processor on some Motorola phones and tricking some older 2G GSM networks into not delivering calls and messages. The hack could shut down some small localised mobile networks by spying on the messages sent from phone towers and not delivering them.

open sourcenetwork integritysecurity protocolEnhance Network Integrity By Securing DNS With DNSCrypt
This open-source software for Mac and Linux does for DNS what SSL does for HTTP: It encrypts DNS traffic to prevent spoofing, snooping, and man-in-the-middle attacks.. Like most of the network protocols and systems in widespread use today, the Domain Name System (DNS) harbors significant security vulnerabilities. Though DNS provides a deceptively simple service -- translating human-friendly website addresses such as https://www.cnn.com/ into computer-friendly numerical IP addresses such as -- the system's integrity is a crucial cornerstone of Internet operations and trustworthiness. One common attack on the DNS infrastructure is called "DNS spoofing." In this type of attack, also known as "DNS cache poisoning," an attacker tricks a DNS server into returning an incorrect IP address for a target website. For example, an attacker might perform cache poisoning on the DNS entry for a legitimate bank's website, thereby directing visitors to the hacker's fake look-a-like site in order to capture their login or banking details. This type of attack is difficult for users to detect, because the website address displayed in the user's web browser is not altered in any way. A single compromised DNS server at an Internet Service Provider can in this way affect potentially thousands of users. The link for this article located at eSecurity Planet is no longer available. .

cybersecuritydefense strategiesthreat preventionEffective Strategies for Securing Your Network Against Hackers
I remember being excited when I was asked to use a sledgehammer to tear down a covered garage that wasn't approved by the city. It had been standing beside my girlfriend's house for years. You could tell it was built intelligently and with love. The supporting beams were twice as thick as required by code, and every nail and screw was driven straight. The lumber itself was top shelf, not a knot or bend in it.. I have a hard time driving a nail straight -- yet it took me less than an hour to turn the structure into a crumpled pile of lumber. In the security world, something similar happens every day when hackers tear down whole networks and systems. The link for this article located at InfoWorld is no longer available. .

Hardly a day goes by that we don't hear new information about some company getting themselves hacked. Sure they all have firewalls, but HOW are the hackers getting in? I was hired to perform an application security audit for a local university. They wanted to make sure that they didn't become part of the growing statistics. . Exploit Video (9mb Download) Exploit Fixed (1mb Download) What you've just witnessed is an applicaiton vulnerability. I didn't attack the operating system, I simply interacted with and manipulated data given to me by the web server. As you can see, these attacks are staggeringly simple.

For enterprises today, the network is where business takes place. Every department in an organization relies on the network for applications and for a growing share of communications, not only e-mail and instant messaging, but soon telephony as well. The mission of network security is to ensure that applications can do their jobs and that applications have the network bandwidth and the availability needed to support the operations of the company. There's also a broader perspective on network requirements. It's a holistic view that encompasses security as well as availability, bandwidth and control. We call it network integrity. This is the real goal behind securing a network. When the network is functioning properly, providing applications with the bandwidth and availability they need, then the network has integrity, and security is doing its job, even when the network is under attack.

The value of a computer's information determines its desirability as a target for hacking -- but only in part. Even valueless machines can serve as jumping-off sites for additional attacks once compromised, or be used to gather information about an ostensibly "private" network in preparation for a later intrusion. And of course, mischief is an endless source of motivation. Knowledge of what the network should look like is worthless unless regularly compared to the way it is. I'm using "network" here to refer to the sum of all networked computers, not to router and switch security, which is a completely different matter. "Securing the network," in this sense, means preventing remote users from gaining access to your machines. The link for this article located at Certcities is no longer available. .
