SBOMs in Action: Securing Your Golden AMIs From Build to Runtime

Aggregated on: 2024-07-15 20:23:25

Golden Amazon Machine Images (AMIs) are the foundation for launching consistent and efficient instances in your AWS cloud environment. Ensuring their security and immutability is paramount. This guide delves into how Software Bill of Materials (SBOMs), cryptographic signing, and runtime validation create a robust framework for building and maintaining secure golden AMIs. Steps Involved in Building Golden AMIs Step Description Start with a Trusted Base Image Begin by selecting a minimal, reputable base image, such as AWS-provided base AMIs that are regularly updated with the latest security patches. Add Necessary Packages Install required packages using package managers like yum, apt, or pip. Ensure that packages are sourced from trusted repositories and specify version numbers for consistency. Configure Users and Permissions Follow the Principle of Least Privilege when creating user accounts, removing unnecessary default users and groups. Configure SSH for key-based authentication and restrict root access. Functional Testing Verify the functionality of installed software and applications, including network connectivity and essential system services, to ensure everything works as expected. Vulnerability Scanning Utilize tools such as Amazon Inspector or Grype to scan the AMI for vulnerabilities. Address any critical findings promptly to mitigate potential security risks. Understanding Drift and Its Causes AMI drift occurs when a running instance diverges from its original AMI configuration. This can result from ad-hoc administrator modifications, automated patching, configuration management tools like Puppet or Chef, and changes by application users. These deviations emphasize the need for ongoing monitoring and management of AMI configurations in cloud environments to maintain system consistency and security.

Choosing the Best CSS Frameworks for Enterprise Web Applications

Aggregated on: 2024-07-15 16:23:25

The heart of the web application is Cascading Style Sheets (CSS), which allows you to style your web pages and make them look better and richer. There are many CSS frameworks available for you to choose from when architecting an enterprise web application. These frameworks often provide you with responsive standard styles that are pre-built for the same purpose. When choosing a particular framework, look for specific product requirements; it also allows for more customization and the ability to scale and perform when tied to the web app. I will be making a detailed analysis of some popular CSS frameworks like Bootstrap CSS, Tailwind CSS, Chakra UI, and Next UI. 1. Tailwind CSS Overview As per its definition, Tailwind CSS is a utility-first CSS framework for rapidly building modern websites without ever leaving your HTML. This allows the developers to directly inject the classes into the respective HTML elements. This takes away all the groundwork that the developer has to do to spin the web page with proper styling. In short, there is no need to maintain an external style sheet. It's easy to customize and scale.

Why Creating Wrapper Classes for Component Libraries Is a Great Idea in Web Development

Aggregated on: 2024-07-15 15:38:25

No wonder there are tons of third-party component libraries available that can be integrated into your project to speed up the development process. Libraries like Angular Material UI, Bootstrap, Chakra UI, Next UI, and others offer various other rich features that are lightweight, fast, and adhere to accessibility norms. However, direct access to library components without an abstraction layer could lead to numerous inconsistencies and maintainability issues in the future. This is the primary reason I insist on creating classes that encapsulate the original composition, which I refer to as wrapper classes. These classes are easy to create and allow more flexibility and consistency when building an enterprise web application. Benefits of Creating Wrapper Classes 1. Consistency When it comes to consistency, I mean the look and feel of the components throughout the web application. Would you allow dropdowns or radio buttons to appear differently? The answer is no. Wrapping ensures uniformity and consistency across the app, enabling the components to seamlessly integrate with the product's specific branding. Here, branding refers to the themes and skins of the common components that you will use throughout the app.

Testcontainers-Based Load Testing Bench

Aggregated on: 2024-07-13 13:08:24

Using Testcontainers has radically improved the process of working with test scenarios. Thanks to this tool, creating environments for integration tests has become simpler (see the article Isolation in Testing with Kafka). Now we can easily launch containers with different versions of databases, message brokers, and other services. For integration tests, Testcontainers has proven indispensable. Although load testing is less common than functional testing, it can be much more enjoyable. Studying graphs and analyzing the performance of a particular service can bring real pleasure. Such tasks are rare, but they are especially exciting for me. The purpose of this article is to demonstrate an approach to creating a setup for load testing in the same way that regular integration tests are written: in the form of Spock tests using Testcontainers in a Gradle project environment. Load-testing utilities such as Gatling, WRK, and Yandex.Tank are used.

Why You Need to Shift Left With Mobile Testing

Aggregated on: 2024-07-12 21:08:24

I feel like there’s always been a love-hate relationship with the concept of testing. Without a doubt, the benefits of testing whatever you are building help avoid customers reporting those same discoveries. That’s the love part of the relationship. The hate part is when project timelines cause testing to become a lower priority…often to the point where it becomes a backlog wishlist item that rarely surfaces in a current sprint. This almost guarantees customers will contact you with unexpected outcomes.

Implementing Micro Frontends in Angular: Step-By-Step Guide

Aggregated on: 2024-07-11 23:08:23

Micro frontends are architectural styles in which independently deliverable frontend applications form a unified whole. This method enables teams to work independently on different parts of an application for scalability and easier maintenance. This guide will demonstrate how to implement micro frontends in Angular applications, the benefits and challenges, and the steps with code samples. Benefits of Micro Frontends Scalability: Teams can develop, test, and deploy features independently, scaling the development process. Autonomous teams: Different teams can work on separate micro frontends, using their preferred tools and frameworks. Maintainability: Smaller codebases are easier to maintain, understand, and refactor. Incremental upgrades: Micro frontends can be updated incrementally without affecting the entire application. Challenges of Micro Frontends Complexity: Increased complexity in managing multiple repositories and coordinating deployments. Performance: Potential performance overhead due to multiple independent bundles. Shared state management: Managing shared state across micro frontends can be challenging. Consistency: Ensuring a consistent look and feel across different micro frontends requires careful planning. When more than one team works on various areas of an application, differences in design and user experience usually creep in. To mitigate this, a solid design system and common component library should be established across all teams. This includes defining a set of UI components, styles, and guidelines that are uniform across the application. It also requires regular communication and collaboration between teams to align on design decisions and consistency.

Aggregated on: 2024-07-10 20:08:23

Exporting Data From GaussDB Comparison of Export Methods Export Tool Export Steps Applicable Scenarios and Notes Using GDS Tool to Export Data to a Regular File SystemNote: The GDS tool must be installed on the server where the data files are exported Remote Export Mode: Export business data from the cluster to an external host. 1. Plan the export path, create GDS operation users, and set write permissions for the GDS user on the export path. 2. Install, configure, and start GDS on the server where data will be exported. 3. Create an external table in the cluster, with the location path in the format "gsfs://192.168.0.90:5000/".Local Export Mode: Export business data from the cluster to the host where the cluster nodes are located. This strategy is tailored for numerous small files. 1. Plan the export path and create directories to store exported data files on each DN in the cluster, such as "/output_data", and change the owner of this path to omm. 2. Install, configure, and start GDS on the server where data will be exported. 3. Create an external table in the cluster, with the location path in the format "file:///output_data/". GDS tools suitable for scenarios with high concurrency and large data exports. Utilizes multi-DN parallelism to export data from the database to data files, improving overall export performance. Does not support direct export to HDFS file system.Notes on Remote Export: 1. Supports concurrent export by multiple GDS services, but one GDS can only provide export services for one cluster at a time. 2. Configure GDS services within the same intranet as the cluster nodes. Export speed is affected by network bandwidth. The recommended network configuration is 10GE. 3. Supported data file formats: TEXT, CSV, and FIXED. Single-row data size must be <1GB.Notes on Local Export: 1. Data will be evenly split and generated in the specified folders on the cluster nodes, occupying disk space on the cluster nodes. 2. Supports data file formats: TEXT, CSV, and FIXED. Single-row data size must be <1GB. gs_dump and gs_dumpall Toolsgs_dump supports exporting a single database or its objects.gs_dumpall supports exporting all databases in the cluster or common global objects in each database. The tools support exporting content at the database level, schema level, and second level. Each level can be separately defined to export the entire content, only object definitions, or only data files. Step 1: The omm operating system user logs into any host with MPPDB service installed and executes: source $ {BIGDATA_HOME}/mppdb/.mppdbgs_profile command to start environment variablesStep 2: Use gs_dump to export the postgres database: gs_dump -W Bigdata@123 -U jack -f /home/omm/backup/postgres_backup.tar -p 25308 postgres -F t 1.

Dynamic Watermarking on the JVM

Aggregated on: 2024-07-10 19:08:23

Displaying images on your website makes for an interesting problem: on one side, you want to make them publicly available; on the other, you want to protect them against undue use. The age-long method to achieve it is watermarking: A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio, video or image data. It is typically used to identify ownership of the copyright of such signal. "Watermarking" is the process of hiding digital information in a carrier signal; the hidden information should, but does not need to, contain a relation to the carrier signal. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for banknote authentication.

How To Build an AI Knowledge Base With RAG

Aggregated on: 2024-07-09 23:23:22

Large Language Models are immensely powerful and can quickly generate intelligent and natural-sounding responses. Their major problem, however, is a limitation of training data – GPT-4, for instance, has a knowledge cutoff date in September 2021. This means that the model is unaware of any events or developments after this date. LLMs also have consistent troubles with the accuracy of information and “hallucinations” – coherent and logical, but factually incorrect responses. Finally, LLMs are unaware of specific, niche information, and can only generate responses on a certain level of generality. To solve these issues and make the LLM usable for specific and information-heavy tasks, LLMs can be connected to AI knowledge bases – repositories of information that consist of organized data – product documentation, articles, messages, and other materials. In this article, I explain how to create a knowledge base that would later be connected to the LLM model and enable it to generate factually correct and specific responses.

Mitigate the Security Challenges of Telecom 5G IoT Microservice Pods Architecture Using Istio

Aggregated on: 2024-07-09 23:23:22

Deploying microservices in a Kubernetes cluster is critical in 5G Telecom. However, it also introduces significant security risks. While firewall rules and proxies provide initial security, the default communication mechanisms within Kubernetes, such as unencrypted network traffic and lack of access control, are inherently insecure. This insecurity could compromise sensitive data. Therefore, implementing additional security measures within each microservice pod is not just a recommendation but a crucial step to ensure secure communication within the cluster. So, additional configuration inside each application is needed. Istio provides a robust solution to these challenges by effectively managing communication between individual 5G telecom microservice pods. With its control plane, Istio automatically injects a sidecar proxy into individual microservices pods, ensuring secure and efficient communication.

Securing Your Machine Identities Means Better Secrets Management

Aggregated on: 2024-07-09 23:23:22

In 2024, GitGuardian released the State of Secrets Sprawl report. The findings speak for themselves; with over 12.7 million secrets detected in GitHub public repos, it is clear that hard-coded plaintext credentials are a serious problem. Worse yet, it is a growing problem, year over year, with 10 million found the previous year and 6 million found the year before that. These are not cumulative findings! When we dig a little deeper into these numbers, one overwhelming fact springs out: specific secrets detected, the vast majority of which are API keys, outnumber generic secrets detected in our findings by a significant margin. This makes sense when you realize that API keys are used to authenticate specific services, devices, and workloads within our applications and pipelines to enable machine-to-machine communication. This is very much in line with research from CyberArk, machine identities outnumber human identities by a factor of 45 to one. This gap is only going to widen continually as we integrate more and more services in our codebases and with ever-increasing velocity.

Cache Wisely: How You Can Prevent Distributed System Failures

Aggregated on: 2024-07-09 23:23:22

Caching is often implemented as a generic solution when we think about improving the latency and availability characteristics of dependency service calls. Latency improves as we avoid the need to make the network round trip to the dependency service, and availability improves as we don’t need to worry about temporary downtimes of the dependency service given that the cache serves the required response that we are looking for. It is important to note that caching does not help if our requests to a dependency service lead to a distinct response every time, or if a client makes vastly different request types with not much overlap between responses. There are also additional constraints to using caching if our service cannot tolerate stale data. We won’t be delving into caching types, techniques, and applicability as those are covered broadly on the internet. Instead, we will focus on the less talked about risk with caching that gets ignored as systems evolve, and this puts the system at risk of a broad outage.

Enhancing Security With ZTNA in Hybrid and Multi-Cloud Deployments

Aggregated on: 2024-07-09 23:23:22

Today’s network infrastructure is rapidly changing with the adoption of hybrid and multi-cloud architectures to leverage the benefits of flexibility, scalability, and redundancy. These advantages come with their own set of challenges, particularly in securing access to resources and users spread across cloud environments. Zero Trust Network Access (ZTNA) ensures secure connectivity in diverse and complex infrastructures. Understanding ZTNA in Hybrid and Multi-Cloud Environments The Zero Trust Network Access (ZTNA) marks a major shift from the traditional perimeter-based security which treats traffic as untrustworthy, irrespective of its source. Network segmentation is not the only reliable method of providing security. ZTNA checks every access request based on user identity, device security posture, and contextual factors before granting access to applications and data.

Master AWS IAM Role Configuration With Terraform

Aggregated on: 2024-07-09 23:23:22

It's super important today to keep things secure and make sure everything is running as it should. AWS Identity and Access Management (IAM) helps with this by letting you manage who can get into what parts of your AWS account. One cool thing about IAM is that it lets you give permissions to different parts or people in your account without having to share sensitive info like passwords. Today, I'm going to talk about using Terraform, a tool that lets you set up infrastructure through code, to create and set up these IAM roles easily. Understanding AWS IAM Roles and Terraform Before we get into how to use Terraform for setting up IAM roles in AWS, it's key to grasp what AWS IAM roles and Terraform are all about. In your AWS account, you can create IAM roles, which are basically identities with certain permissions attached. These roles let you give specific rights to different parts of your AWS setup without any hassle. On the flip side, Terraform is a tool that lets you manage your infrastructure through code instead of doing everything manually. It’s made specifically for working smoothly with services such as those offered by AWS, thanks to the Terraform AWS provider.

Mastering Serverless Debugging

Aggregated on: 2024-07-09 06:23:22

Serverless computing has emerged as a transformative approach to deploying and managing applications. The theory is that by abstracting away the underlying infrastructure, developers can focus solely on writing code. While the benefits are clear—scalability, cost efficiency, and performance—debugging serverless applications presents unique challenges. This post explores effective strategies for debugging serverless applications, particularly focusing on AWS Lambda. Before I proceed I think it's important to disclose a bias: I am personally not a huge fan of Serverless or PaaS after I was burned badly by PaaS in the past. However, some smart people like Adam swear by it so I should keep an open mind.
