7 Tips for Creating Easy-to-Validate PDF Signatures

Aggregated on: Tue Oct 19 2021 23:41:55 GMT+0000 (Coordinated Universal Time)

Validating digital signatures in PDF documents is a tricky business, and contrary to popular belief, there’s no one true validation algorithm. I’m not going to try to tell you how to validate PDF signatures—that’d be hard to do in a blog post anyhow. Instead, I’ll turn things around, and try to give you some advice on how to produce PDF signatures that are easy to digest (pun intended) for validators. Most of the content of this post is geared towards producing signatures for public workflows, i.e., cases where you don’t know who is going to need to validate your signature, so aiming for maximal interoperability is important. Most of the advice is still relevant for other, closed workflows as well, but it depends on the circumstances.

Watching the Requests Go By: Reconstructing an API Spec with APIClarity

Aggregated on: Tue Oct 19 2021 22:41:54 GMT+0000 (Coordinated Universal Time)

Reconstructing an OpenAPI Specification through Observation APIs are ubiquitous in modern microservice architectures. They make it easy to consume data from external apps and reduce the amount of code developers need to write. The general result is easier delivery of useful software products. However, the prevalence of APIs means they represent a large attack surface. In fact, Gartner predicts that by 2022, API attacks will be the most common attack vector for enterprise web applications. Similarly, an IBM report found that two-thirds of data breaches could be traced to misconfigured APIs. Clearly, enterprises need to take a proactive approach to ensure their use of APIs is secure. Unfortunately, with the complexity of modern apps, third-party code dependencies, and a lack of documentation, API observability is a huge challenge. Often, enterprises simply don’t have any API specifications for their production apps. As a result, security-related misconfigurations go undetected, and apps use a variety of deprecated “zombie APIs” and undocumented “shadow APIs” in production.

Why Cloud-Native Apps Need Cloud-Native Ransomware Protection

Aggregated on: Tue Oct 19 2021 22:41:54 GMT+0000 (Coordinated Universal Time)

The statistics are chilling. Last year, there were nearly 300 million ransomware attacks. That’s a 72% increase during the pandemic. And each successful attack nets an average ransom of $300,000. That number represents a 171% increase during the same period. And the threat is escalating as attackers become more organized, more capable, and exploit new entry points, like mobile and edge devices. There are no guarantees in defending an enterprise cloud environment from ransomware. And if your applications are cloud-native, you have an elevated set of worries owing to the particular challenges of securing reliable point-in-time backups or check points that include data volumes as well as application configuration information (metadata). If you consider that emerging ransomware threats target the backups themselves — via the operator console or the physical devices — enterprises have some important choices to make about how they are going to reliably secure their data (and their users’ data) for business continuity and regulatory compliance.

In this blog, you will learn how to deploy a basic Dockerized Spring Boot application to AWS Fargate. AWS Fargate is a serverless AWS environment. Enjoy! 1. Introduction In a previous post, you learned how to deploy a basic Dockerized Spring Boot application on an AWS ECS Cluster. You learned about the different components like the ECR Docker repository, Task Definitions, the ECS Cluster itself and Services. It is advised to read that post first when these components are new to you. In this post, you will create and deploy the same Dockerized Spring Boot application. This time you deploy it to AWS Fargate. AWS Fargate is identical to AWS ECS Cluster, but this time you will not need to manage the EC2 instances yourself which is a great advantage! It is completely serverless.

Aggregated on: Tue Oct 19 2021 18:26:54 GMT+0000 (Coordinated Universal Time)

Financial institutions have embraced digital innovation at a recorded pace to adopt new ways of working, serving the financial needs of customers, and keeping the markets performing. Moreover, they have done so while still operating within their control frameworks and regulatory requirements needed to serve in all parts of the world. According to the 2020 Frost and Sullivan Global Cloud User Survey, “multi-cloud adoption has skyrocketed among financial firms in the past year, up nearly 70%. In addition, hybrid cloud adoption — already higher among financial firms than other industries — is up 8%. In response to the pandemic, financial firms are accelerating their cloud journeys, knitting together disparate IT environments (on‑premises, edge, and multiple clouds) as a foundation for digitalization.”

Here’s How You Can Purge Big Data From Unstructured Data Lakes

Aggregated on: Tue Oct 19 2021 17:56:54 GMT+0000 (Coordinated Universal Time)

Without a doubt, big data is becoming the biggest data with the passage of time. It’s going above and beyond. Here are some pieces of evidence as to why I said it. According to the big data and business analytics report from Statista, the global cloud data IP traffic will reach approximately 19.5 zettabytes in 2021. Moreover, the big data market will strike a figure of 274.3 billion US dollars with a five-year compound annual growth rate (CAGR) of 13.2% by 2022. Plus, Forbes predicted that over 150 trillion gigabytes or 150 zettabytes of real-time data will be required by the year 2025. Also, Forbes found that more than 95% of the companies need some assistance for the management of unstructured data, while 40% of the organizations affirmed that they need to deal with big data more habitually.

The Reports of Perl’s Death Have Been Greatly Exaggerated

Aggregated on: Tue Oct 19 2021 17:26:54 GMT+0000 (Coordinated Universal Time)

Look, I get it. You don't like the Perl programming language or have otherwise disregarded it as "dead." (Or perhaps you haven't, in which case please check out my other blog posts!) It has weird noisy syntax, mixing regular expressions, sigils on variable names, various braces and brackets for data structures, and a menagerie of cryptic special variables. It's old: 34 years in December, with a history of (sometimes amateur) developers that have used and abused that syntax to ship code of questionable quality. Maybe you grudgingly accept its utility but think it should die gracefully, maintained only to run legacy applications. But you know what? Perl's still going. It's had a steady cadence of yearly releases for the past decade, introducing new features and fencing in bad behavior while maintaining an admirable level of backward compatibility. Yes, there was a too-long adventure developing what started as Perl 6, but that language now has its own identity as Raku and even has facilities for mixing Perl with its native code or vice versa.

Dive Deep Into TiKV Transactions: The Life Story of a TiKV Prewrite Request

Aggregated on: Tue Oct 19 2021 16:56:54 GMT+0000 (Coordinated Universal Time)

TiKV is a distributed key-value storage engine, which is based on the designs of Google Spanner, F1, and HBase. However, TiKV is much simpler to manage because it does not depend on a distributed file system. As introduced in A Deep Dive into TiKV and How TiKV Reads and Writes, TiKV applies a 2-phase commit (2PC) algorithm inspired by Google Percolator to support distributed transactions. These two phases are Prewrite and Commit.

Code Quality Software That Makes A Difference

Aggregated on: Tue Oct 19 2021 16:26:54 GMT+0000 (Coordinated Universal Time)

"There is no single question to what does the best quality mean? However, one proven approach is comparing how well a given code interacts with its neighbors in the same technical domain." In the world of software development, code quality often comes to mean a certain level of complexity in a code. The code that is too complex for users or developers to understand or use easily is considered low in quality. Sometimes this means that the code is too complex for even the programmers to understand.

How to Export All Modules to All Modules at Runtime in Java

Aggregated on: Tue Oct 19 2021 15:56:54 GMT+0000 (Coordinated Universal Time)

Due to the new module system, Java 9 does not allow an application by default to see all classes from the JDK, unlike all previous versions of Java. If we try to access some reserved module, we obtain an error like this:module <module-name> does not "opens <package-name>" to unnamed module. Everyone knows that we can solve this exception by using the JVM parameters --add-exports or add-opens, but what if we have more environments, and we don't want to have to change JVM arguments across these environments?

Externalizing Your Configurations With Vault for Scalable Deployments

Java Integration 3. Python Integration 4. Nodejs Integration 5. Ansible Integration Conclusion Introduction: To implement automation for microservices or applications deployed to a large number of systems, it becomes essential to externalize the configurations to a secure, scalable, centralized configuration store. This is necessary to be able to deploy the application in multiple environments with environment-specific parameters without requiring human intervention and without requiring modification to the core application during automated deployments, scaling, and failover recoveries. Besides the fact that manually managed configurations involve the risk of human error, they are also not scalable for 24x7 large-scale deployments, particularly when we are deploying several instances of microservices across various infrastructure platforms.

Angular/Spring Boot Feature Activation by Spring Profile

Use Case Description Sometimes there is the use-case for a system that has the same basic requirements but needs some different logic in the core for different customers. The question is: Do the differences warrant a new microservice or do you put the logic in the same? Basically, the question is: A monolith or a zoo of microservices? The answer depends on the requirements and both extremes are probably wrong.

Azure Function - An Introduction

Aggregated on: Tue Oct 19 2021 11:41:54 GMT+0000 (Coordinated Universal Time)

Today, in this article we will discuss basic concepts of Azure Function. An Azure Function is a perfect example of Serverless architecture or computes service. Using Azure Function, we can run the event-based code without managing any infrastructure. Since the Azure function is a trigger-based service, so it always executes a script of a block of code in response to a variety of events. An Azure Function can also be used to achieve the decoupling, high throughput or response, reusability of code, etc. So, we will discuss the Azure Functions in all aspects in four parts. Today, in the first part of this article series, we will discuss the below topics:

AWS Audit and Security Strengthening

Aggregated on: Mon Oct 18 2021 23:22:22 GMT+0000 (Coordinated Universal Time)

After my previous article on AWS DDoS resiliency, I have decided to take on some of the AWS services which should be a part of any enterprise architecture. These services will help users in raising the posture of the overall security and help in meeting the core security and compliance requirements. AWS has already mentioned security as one of the pillars of their architecture framework and, to support that, AWS provides a wide range of features and services. As a consumer and business owner, we need to understand that it is more of a shared model where AWS is contributing by developing new features based on their rich experience and exposure of multiple domains, and it is up to us to figure out how we can reinforce our security framework using these capabilities.

How to Find the Right Collaborative Coding Tool for Remote Pair Programming

Remote development is clearly here to stay, and when you need to collaborate with your team, starting a Zoom meeting or Hangout (er … Google meeting) is probably something you think of doing first. However, several developer-focused solutions that are much better suited for remote development are available today — but how do you know which one to pick? This guide will help you make that decision. As you read this guide, you might wonder how I know an awful lot about these solutions. The fact is, I work for Genuitec, which makes CodeTogether. What you see below is the result of our continuing study of this landscape to see how we stack up against our competitors and to decide what we need to focus on next. This guide aims to be factual, and in an effort to remain unbiased, I do not delve too deeply into the quality or capabilities of each feature.

Easy Access to OAuth 2.0 Protected Resources With the Spring WebClient

Aggregated on: Mon Oct 18 2021 20:07:22 GMT+0000 (Coordinated Universal Time)

Spring Framework 5.0 introduced Spring WebClient as part of the WebFlux reactive web stack. WebClient is a reactive HTTP client that provides a functional and fluent API based on Reactor, allowing declarative composition of asynchronous non-blocking requests. No need to manage concurrency issues. Support for filter registration means it can intercept and modify requests, which can be used for cross-cutting concerns such as authentication, as demonstrated in this tutorial. The WebTestClient is also an HTTP client designed for application testing. With a testing interface wrapper to check replies, WebClient can be used to execute end-to-end HTTP testing and connect to a live server. It can also bind to a controller or application context and simulate requests and responses without requiring a running server.

REST Services With Apache Camel

Aggregated on: Mon Oct 18 2021 18:37:22 GMT+0000 (Coordinated Universal Time)

Microservices are becoming a very popular architectural style for developing greenfield applications and also for brownfield solutions. People are moving away from the monolith solutions due to added advantages like faster development and go-to-market, increased adoption of containerization and small teams, and a lighter codebase. You can use either Spring Boot, Quarkus, or Lagom frameworks to develop the REST services. I would like to show how we can use Apache Camel, a leading opensource integration framework, to write REST services easier and quicker using the REST domain-specific language (DSL).

Kotlin and FaaS, An Impossible Union?

Some time ago, I read a post describing how to run a serverless Kotlin function on OpenFaaS. While the content is technically correct, I believe the concept itself is very wrong. Such posts can lead people to make ill-advised decisions: "because we can" is hardly a winning strategy. In this post, I'd like to first explain why the JVM platform is a bad idea for FaaS. Then, I'll proceed to propose alternatives to use Kotlin nonetheless. I deliberately chose not to link to the original post to avoid lending it any credibility. If you want to read it anyway, Google is your friend.

Leveraging AWS for Backup and Disaster Recovery — 8 Best DR Practices

Aggregated on: Mon Oct 18 2021 15:07:21 GMT+0000 (Coordinated Universal Time)

Today, all companies are technology companies. Yet, Invenio IT reports that every 1 in 5 organizations does not have a disaster recovery plan. A company without a disaster recovery is prone to the type of IT disaster including server corruption, data center failures, cyberattacks, etc., that can disrupt the entire functioning of day-to-day operations. Most organizations back up their data on tapes, which are pretty expensive and difficult to maintain. The restoration process is also time-consuming and such solutions are often not viable for backups. AWS offers extremely reliable backup and disaster recovery solutions that are not just secure but are highly flexible and scalable. It is also extremely effective for better RPO (Recovery Point Objective) and RTO (Recovery Time Objective) in disastrous situations.

Porting Software to ARM: Here’s What We Learned

Aggregated on: Mon Oct 18 2021 13:37:21 GMT+0000 (Coordinated Universal Time)

AWS’s release of its Graviton instance in 2019 has sparked a lot of interest in server-side ARM. And for good reason--moving to Graviton can save up to one-third of compute costs without sacrificing performance. With high demand, but constrained infrastructure budgets, this is a big deal! While there has been great interest in using ARM in the data center for a long time, adoption has been slow - it was too hard to source ARM-based servers and port the entire software stack to ARM. With the introduction of Graviton, it’s now as easy to spin up an ARM instance as an x86 instance. But what about porting your software?

Use Ketch to Deploy Apps on Kubernetes Without YAML

Aggregated on: Sun Oct 17 2021 19:26:44 GMT+0000 (Coordinated Universal Time)

Ketch, a relatively new open source project from application-as-code platform Shipa, offers a simple command-line interface that developers can use to deploy and manage applications on any Kubernetes cluster without writing YAML configuration files. Kubernetes is the ubiquitous standard for orchestrating containerized and microservices-based applications. However, operating Kubernetes requires developers to overcome a rather steep learning curve. Running Kubernetes successfully means gaining expertise in Kubernetes concepts, objects, and how to write and manage YAML files. Ketch eliminates much of that complexity by deploying applications directly to Kubernetes clusters, rendering YAML files unnecessary and easing entry for developers.

How to Add a Favicon To make an icon display, you need to add a file with a graphic image of the icon to a tab. To add an icon to your website, you need to follow the mandatory browser requirements and use a minimum set of favicons, which we will now consider in detail. Why a set and not a single icon? The fact is that browsers and screens are constantly evolving. More modern formats are usually supported by more modern browsers. For example, you might think that you can add a single SVG icon and the browser will render it correctly. However, not all browsers still support the SVG format for favicons. The following table illustrates the browsers that support the SVG format.

The new LTS version (version 17) of Java was released in September. And since the previous LTS (version 11), many cool features were added. One of the coolest ones is “Pattern Matching for instanceof“. Until Java 15, when we checked whether an object is an instance of a particular class, the compiler didn’t infer the variable’s type, even if the object passed the condition. Because of that, we always had to cast after the instanceof check.
