Understanding Kernel Monitoring in Windows and Linux

Aggregated on: 2024-03-11 23:12:16

The cybersecurity landscape is undergoing a significant shift, moving from security tools monitoring applications running within userspace to advanced, real-time approaches that monitor system activity directly and safely within the kernel by using eBPF. This evolution in kernel introspection is particularly evident in the adoption of projects like Falco, Tetragon, and Tracee in Linux environments. These tools are especially prevalent in systems running containerized workloads under Kubernetes, where they play a crucial role in the real-time monitoring of dynamic and ephemeral workloads. The open-source project Falco exemplifies this trend. It employs various instrumentation techniques to scrutinize system workload, relaying security events from the kernel to user space. These instrumentations are referred to as ‘drivers’ within Falco, reflecting their operation in kernel space. The driver is pivotal as it furnishes the syscall event source, which is integral for monitoring activities closely tied to the syscall context. When deploying Falco, the kernel module is typically installed via the Falco-driver-loader script included in the binary package. This process seamlessly integrates Falco’s monitoring capabilities into the system, enabling real-time detection and response to security threats at the kernel level.

From Kotlin Scripting to Python

Aggregated on: 2024-03-11 18:12:16

GitHub offers a way to customize one's profile by allowing one to create a README in a specific repository, named as your profile, e.g., nfrankel/nfrankel. A couple of years ago, I automated the update of my GitHub profile with up-to-date info: my latest blog posts, my upcoming talks, and the last recorded YouTube talk. I took the time to document how to do it on this blog. At the time, I chose Kotlin scripting because I was proficient enough in Kotlin, but I wanted to learn the scripting part. Over the years, I became more and more dissatisfied with the solution. I recently moved away from Kotlin Scripting to Python. In this post, I want to explain my reasons and document the migration.

Feature Flags and Canary Releases in Microservices

Aggregated on: 2024-03-11 18:12:16

Feature flags are commonly used constructs and have been there for a while. But in the last few years, things have evolved and feature flags are playing a major role in delivering continuous risk-free releases. In general, when a new feature is not fully developed and we still want to branch off a release from the mainstream, we can hide our new feature and toggle it off in production. Another use-case is when we want to release our feature to only a small percentage of users, we set the feature 'on' for a segment/geography and set it 'off' for the rest of the world. The capability to toggle a feature on and off without doing a source code change gives the developer an extra edge to experiment with conflicting features with live traffic. Let us deep dive into more details about feature flags and an example implementation in Springboot. Things To Consider When We Are Introducing a New Feature Flag Establish a consistent naming convention across applications, to make the purpose of the feature flags easily understandable by other developers and product teams. Where to maintain feature flags? In the application property file: Toggle features based on environment. Useful for experimenting in development while keeping features off in production. In configuration server or vault: Let's imagine you are tired after a late-night release, and your ops team calls you at 4 am, to inform you the new feature is creating red alerts everywhere in monitoring tools, here comes the Feature toggle to your rescue. First, turn the feature 'off' in the config server and restart compute pods alone, In database or cache: Reading configs or flag values from a database or an external cache system like Redis, you don't have to redeploy or restart your compute, as the values can be dynamically read from the source at regular intervals, pods get updated value without any restart. You can also explore open-source or third-party SDKs built for feature flags, a handful of them are already in the market. They also come with additional advantages that help in the lifecycle management of feature flags.

Beyond the Call: AI and Machine Learning’s Role in Evolving Vishing Cyber Threats

Aggregated on: 2024-03-11 17:12:16

Vishing, a fusion of "voice" and "phishing," represents a sophisticated social engineering tactic that leverages telephonic communication to extract sensitive personal or administrative information. Though not a novel concept, historical instances underscore the enduring efficacy of vishing in breaching security barriers. MGM Cyber Attack Analysis Against the backdrop of historical precedents, the MGM Resorts cyberattack in September 2023, orchestrated by the Scattered Spider group utilizing ALPHV/BlackCat ransomware, stands out as a poignant example. Employing vishing as a pivotal element, the assailants adeptly simulated an MGM employee during a call to the IT help desk, successfully obtaining credentials that were then used to disrupt critical services such as card payments, knock out reservations sites, shut down ATMs and locked guests out of their hotel rooms. The ensuing compromise of customer data prompted MGM Resorts to implement comprehensive measures, including free credit monitoring.

Why Do We Need Databases and SQL?

Aggregated on: 2024-03-09 00:27:14

SQL has a long and proven history. It has survived the fuss around NoSQL. Even if it is not perfect, it has been demonstrated to be the best available language for data. This is no surprise! The story began in the 1960s with the development of databases—an era marked by the introduction of the Integrated Data Store (IDS) at General Electric. However, it was Edgar Codd’s relational model that revolutionized data handling. His model, which turned data into a series of tables (or, more strictly, relations), has influenced database systems ever since. This era also saw the birth of SQL (Structured Query Language), which became the standard language for interacting with relational databases, including MariaDB and others. The Utility of Relational Database Systems So, why do we need all this database stuff? Let’s imagine you’re building an app, maybe a simple to-do list to keep track of your daily tasks. Initially, you might think, “Why not just save each task directly to a file?” After all, my programming language has constructs and libraries to save and read data from disk. Also, implementing this seems straightforward: create a task, write it to a file, delete a task, and remove it from the file. These are good points; however, as your app gains traction, users start to aggregate, and suddenly, you have thousands of users trying to add, delete, and modify tasks simultaneously. At this point, the simplicity of files becomes fragile. Imagine one user is updating a task at the exact moment another tries to delete it. Or maybe two users are editing the same task at the same time. With a simple file system, you’re likely to end up with corrupted or lost data because there’s no inherent mechanism to handle such conflicts.

Java Thread Dump Analysis

Aggregated on: 2024-03-07 18:27:13

Thread dump analysis is a traditional approach followed to analyze the performance bottlenecks in Java-based applications. In the modern era, we have APM tools that provide various metrics and screens to drill down and identify performance issues, even at the code level. But for some of the performance issues or occasions, thread dump analysis still stands as the best way to identify the bottlenecks. When To Use a Thread Dump To analyze any performance issue, it is good to take a series of thread dumps with a 1 to 2-second time gap. Taking 10-15 thread dumps each with 1-2 second intervals helps to analyze the threads that got stuck or execute the same code across thread dumps.

What Is Incident Management? Incident management is the process of identifying, responding, resolving, and learning from incidents that disrupt the normal operation of a service or system. An incident can be anything from a server outage, a security breach, a performance degradation, or a customer complaint. Incident management aims to restore the service as quickly as possible, minimize the impact on users and the business, and prevent the recurrence of similar incidents. Incident Management Checklist Incident management can be a complex and stressful process, especially when dealing with high-severity incidents that affect a large number of users or have a significant business impact. To help you navigate the incident management process, here is a checklist of the main steps and best practices to follow:

Why DevOps Should Own Their Databases and How To Do It

Aggregated on: 2024-03-07 15:27:13

DevOps is not new. Ideas to combine deployment and operations began to appear in the late 80s. It took us nearly 20 years to finally formulate the state of DevOps and begin the move towards DevOps engineers. However, we can’t stop here. While it may sound surprising, there is much more to be done than what we already did. Bringing deployments and operations together is just the first step, and we need to bring other areas together even more. Let’s see what exactly. What We Have and What We Lack We went through a big transformation in recent decades. We moved from monolithic applications to microservices. We deploy changes many times a day, and we use multiple platforms together. The database complexity increased tremendously. We now have many databases, both SQL and NoSQL, and specific solutions for domains like machine learning. We can’t manage our databases the same way we did fifteen years ago. Even though we merged development and deployment, there are other aspects that we have disregarded until now. Some of them get bigger traction, such as DevSecOps (bringing security into the process) or ML Ops (bringing research and development together). However, we still lack good database ops solutions. Databases are still terra incognita for developers. They don’t manage them, they don’t optimize them, and they don’t know how to monitor and tune them efficiently. This is a gap that we need to address immediately. Read on to understand why.

Time Data Series: Getting Started With PHP Zmanim

Aggregated on: 2024-03-07 12:42:13

Acknowledgments In this blog, I’m explaining concepts and techniques related to both the way so-called “Jewish times” (zmanim) are calculated; as well as the techniques needed to use the PHP Zmanim library – a library of functions that let you easily calculate Jewish times. The PHPZmanim library is maintained by Zachary Weixelbaum. As with so many things in tech today, PHP Zmanim is itself based on the foundational Kosher Java library by Eliyahu Hershfeld. I owe a huge debt of gratitude to both Zachary and Eliyahu — not only for the work they put into developing those libraries but also for the support they have given me as I came up to speed on both the technical and Jewish religious guidelines (halacha) needed to use them.
