Is It Difficult to Bypass Protection That Uses Big Data?

Aggregated on: 2021-11-17 04:50:58

Today I want to talk about big data in cybersecurity, or rather, how easy or difficult it is to bypass protection systems that use big data. In other words, how to fool advanced threat detection systems, past the all-seeing eye of which, according to marketers, no extra byte can slip through. I am talking about systems that use big data analytics as one of the main tools for detecting suspicious activity like SIEM and XDR. Medium and large businesses usually use such platforms. They have big networks and cloud infrastructure where millions of events occur every hour. Naturally, there is no way to analyze them manually. It is conducted with the intensive use of technical means. And it is important to note that the availability of qualified specialists — both in the field of big data and in the field of cybersecurity — is a necessary component here.

J-Fall 2021 Impressions

Aggregated on: 2021-11-16 21:05:57

The 4th of November, the J-Fall conference was organized by the NLJUG. J-Fall is the largest one-day Java conference in the Netherlands. I attended the conference and with this post, I want to share some of my impressions. Enjoy! 1. Introduction It was already the 18th edition of J-Fall and it was a live event. Of course, some COVID measures were in place, but it was a relief that it was finally possible again to attend a live event. J-Fall was held at the Pathé cinema theater at Ede which is a great location for such an event. The main room 9 is really impressive! Due to COVID measures, only 1.300 participants were allowed instead of the usual 1.500. You had to be quick to register because the event was sold out in nearly one day. More than 60 sessions were held, which makes choosing where to go quite a difficult task. But, do not worry, all sessions are recorded and will be made available via the NLUG YouTube channel. As said before, it is a one-day conference, although they cheated a bit this year because also a pre-conference was held :-).

AI for Cloud-Based SaaS Applications To Enable Efficient Remote Work in 2022

Aggregated on: 2021-11-16 17:05:57

The recent pandemic has emphasized the need for remote work. Especially for businesses that did not have remote capabilities, the need arose for reliable SaaS-based solutions to meet immediate demand. Migration to the Cloud and SaaS-based solutions has been pivotal to remote working capabilities, which is why significant IT expenditure is driven towards it. According to Gartner, the worldwide spending on cloud-based SaaS applications was $120,686 in 2020 and will rise to $171,915 in 2022. However, integrating SaaS-based solutions into your existing system is not that easy, and several repetitive tasks increase the cost.

Zero Trust’s Impact on API Security

Aggregated on: 2021-11-16 15:50:57

Developers are releasing software to keep up with users’ expanding digital presence. Many of those programs rely on Application Programming Interfaces (APIs). Per IBM, APIs enable organizations to connect the data and functionality of their applications with those of other companies. APIs make it easier for companies to deliver and improve the digital products and services on which users rely. It’s therefore no surprise that APIs have grown in recent years. Postman observed that its Collections, or folders where API developers group their API requests, doubled from 17.4 million to 34.9 million between January 2019 and January 2020 alone. As of January 2021, the number of Postman Collections had increased beyond 46 million.

Aggregated on: 2021-11-16 15:20:57

Overview Multitenancy is an operational mode in SaaS applications where various independent instances are allocated to the same environment. To put it simply, multitenancy is having multiple tenants (businesses) use the same Saas application. Multitenancy Archituecture This article will not discuss designing a multitenancy application, however, you can read about it in detail here: What is Multi-Tenant Architecture? From here on, we are going to work on an example about the multi-tenants using multiple databases and microservices architecture.

Becoming Cloud Native

Aggregated on: 2021-11-16 15:05:57

The traditional model of business is undergoing radical change in an endeavor to employ digital technologies better to suit multiple purposes across a variety of sectors, and cloud-native is one of the key drivers that re-architects cloud environments with the intent of adapting the means for how to deliver services. cloud-native is a modern and advanced software development approach; which is why it is becoming of high importance to many companies. Digital Transformation Risks But moving to a new software development approach is not easy, and organizations can be slow to adopt a radical change in the interests of safeguarding their market, output, and business. So, to mitigate risk, organizations can take a step-by-step approach to become cloud-native in several phases, where they can first replicate the new approach on a smaller scale inside a department/team/project architecture to test the results.

Multi-Container Pod Design Patterns in Kubernetes

Aggregated on: 2021-11-16 15:05:57

Pods In Kubernetes, Pods are the single deployable units. If an application is to be deployed it has to be deployed in a Pod as a container. Though applications run in containers, the containers must be part of the Pod. The Pod specification has attribute containers where container specifications are declared. The attribute is plural. That means we can declare more than one container in a Pod specification. Multi-Container Design Consideration But Kubernetes administrators always choose one container Pods over multi-container Pods. One Container Per Pod is an unwritten practice across the industry. Let’s see what advantage a multi-container pod has to offer.

Effortless Cloud-Native App Development Using Skaffold - Book Review

Aggregated on: 2021-11-16 14:35:57

I’m a developer who cares deeply about production. But I’m not a DevOps and unfortunately, I’m pretty bad at that. That’s why when I heard about Skaffold and it instantly piqued my interest. Write Kubernetes cloud-native apps without well… Writing Kubernetes native apps… Sign me up! Unfortunately, as we all know. The time to pick up new technology is when we actually need it and then it’s a rush to get something out. Few of us have time to take off from our busy day to study something and learn something new. That’s why when Ashish Choudhary, the author of the book “Effortless Cloud-Native App Development Using Skaffold” asked for reviewers in the foojay.io slack group, I jumped on the opportunity. I can learn something interesting and be productive (this book review).

2021 Guide On Bridging the Gap Between People Management and Project Management

Aggregated on: 2021-11-16 08:20:57

Project managers in the organizational paradigm are primarily responsible for carrying all of the processes and tasks that are included in the project development process, on their shoulders. They are the backbone of the whole shebang and without them, everything will go to waste. As we all know, that the primary objective of the project managers is to complete all of the projects in their roster at the appropriate time with just the resources that are in the resource pool. But that doesn’t mean that they ignore the most important element related to the whole process, the people.

OAuth 2.0 Session Clustering

Future Javascript: Javascript Pipeline Operators

Aggregated on: 2021-11-16 07:50:57

Pipeline operators are an upcoming feature to Javascript which gives us another way to pass values through a series of transformations. It gives more context to what developers were trying to achieve when they wrote their code and allows us to do some cool things to boot. Here, we'll take a quick look at pipeline operators, how they work, and how you can use them today. Javascript Pipeline Operators: Support Currently, no browser or server-side ECMAScript implementation (like Node.JS) supports pipeline operators. You can, however, get them to work using Babel 7.15. You can learn more about installing Babel here, but suffice to say this will allow you to add pipeline operators into your code.

A Look at IndexedDB

Aggregated on: 2021-11-16 00:50:57

Memory usage is an important metric for Arctype. Developers expect their tools - especially UIs - to be fast and smooth. Recently we improved our memory management algorithms using IndexedDB, Socket.IO, and Typescript. This post takes you inside our reason for the changes, design considerations, implementation, and impact. Prior to this work, querying a database from Arctype was simple. We would grab every row up to 10,000 and load them into memory. We would display a fraction of rows in the results pane, the spreadsheet view, or a chart. When you needed more rows, we would throw out the first 10,000 and fetch another batch.

Google Cloud VMware Engine: Bastion Host Access With IAP

Aggregated on: 2021-11-16 00:20:57

Welcome back! This post will build on the previous posts in this series by deploying a Windows Server 2019 bastion host to manage our Google Cloud VMware Engine (GCVE) SDDC. Access to the bastion host will be provided with Identity-Aware Proxy (IAP). Everything will be deployed and configured with Terraform, with all of the code referenced in this post is available at https://github.com/shamsway/gcp-terraform-examples in the gcve-bastion-iap sub-directory. Identity Aware Proxy (IAP) Overview Standing up initial cloud connectivity is challenging. I walked through the steps to deploy a client VPN in Establishing an SDDC in Google Cloud, but this post will show how to use IAP as a method for accessing a new bastion host. Using IAP means that the bastion host will be accessible without having to configure a VPN or expose it to the internet. I am a massive fan of this approach, and while there are some tradeoffs to discuss, it is a simpler and more secure approach than traditional access methods.

Introduction to Shopify Shopify is a SaaS company that simplifies the process of setting up and running an online business. Businesses that use Shopify have access to important information about their products, orders, customers, and more within Shopify. In most cases, businesses will want to extract this data and combine it with other data into a central database. In this article, we will be discussing how to migrate data from Shopify to Postgres. Create the Postgres Database You need to have a Postgres database in which you will store your Shopify data. You can create the database directly from Postgres, in which you will use the CREATE DATABASE database_name command. For example to give the database the name shopify, run the following command:

Reporting in Microservices: How To Optimize Performance

Aggregated on: 2021-11-15 20:50:57

Microservice architecture is becoming increasingly popular among app developers, thanks to its flexibility and scalability that allows for updates and new features to be added without overhauling the whole system. However, the use of separate user interfaces, databases, and servers for each microservice makes app optimization a challenge, considering the diversity of programming languages and API security issues. The Freshcode team faced the trouble of updating a legacy EdTech app running on MS SQL that used over 10,000 files created in ColdFusion and had dozens of microservices for disparate features. The app was intended for governments and education networks with hundreds of campuses and schools and had a full complement of features to appease both national universities and small schools. With conflicting microservice operations, reporting was a problem the FreshCode team had to tackle.

The Five Dysfunctions of an Engineering Team

Aggregated on: 2021-11-15 15:20:57

Every team has some level of dysfunction. And that’s normal, because teams are made of imperfect human beings. In his book The Five Dysfunctions of a Team, Patrick Lencioni identifies these five basic dysfunctions: Absence of Trust Fear of Conflict Lack of Commitment Avoidance of Accountability Inattention to Results These dysfunctions build upon each other. A team that doesn’t trust each other is afraid to admit their shortcomings and mistakes. Teams like this aren’t vulnerable around each other. This leads to a fear of conflict, where ideas are not openly debated and bad behaviors are not called out for fear of offending someone. Rather than solving underlying problems, the team experiences growing tension manifested by occasionally passive aggressive remarks.

Java is more like English than you think

Aggregated on: 2021-11-15 08:20:56

At a recent in-house event celebrating the launch of Java 17 I was asked to give a talk on the future of the language. I don’t have a hotline to Oracle, so I took the opportunity to dust off my linguistics degree and point out how the nature and comparatively glacial evolution of human languages is not unlike what you can witness in computer languages, compressed within decades. This is the first of two posts based on that talk. In many ways Java, Perl, Haskell, or Lisp are not at all like human languages. Lines of code only resemble English sentences at a very superficial level. Java is one of many specifications to make a digital machine do your bidding, expressed using a small set of English keywords, special characters, and structural rules to make it easy on the brain of the speaker, i.e., the programmer. Regardless of complexity, the behavior of a program follows unambiguously from its content. Sure, you can bang your head against the wall why it does what it does, but given enough eyeballs, even the worst spaghetti code is deterministic.

Strengthen Muscles of Software Systems

Aggregated on: 2021-11-15 08:20:56

While we understand the need for "Building Software Immunity" and the importance of "Secure Software Engineering Habits", it is equally essential for heavy lifters such as software architects, tech leads, or senior engineers to ensure that the core of the software i.e. architecture or design is strong and maintained robust throughout the lifecycle of the software. Strengthening muscles of software goes far into the software development process, deployment and operations. Typically, it can be achieved via embedding security in business requirements, following design principles, and secure design approaches. Embedding Security in Requirements Incorporating security concerns in the early phases of software development is far easier and cost-effective as many common pitfalls can be avoided that get harder to fix later. There are two approaches that can be taken while defining security requirements:

Part 2 - How to Hive on GCP using Google DataProc and Cloud Storage

Aggregated on: 2021-11-14 17:05:56

In part 1 of this series, we have seen how to create a Google Dataproc cluster, create external tables in HIVE, point to the data stored on cloud storage, and perform exploratory data analysis in a staging environment. As part of this analysis, we found out that our sample datasets had around: ~ 11% of non-confirming records for Green Taxi Y2019 dataset ~ 33% of non-confirming records for Yellow Taxi Y2019 dataset Identifying non-confirming records is one of the important steps of exploratory data analysis as they can lead to wrong or faulty interpretation of results. So, as part of the next step, we will create a new environment i.e. new external tables in HIVE with only valid data required for deep-dive analysis and eliminate the non-confirming records.
