The Impact of Covid-19 on Cyber Security
The COVID-19 pandemic causes a huge economic and social disruption which is devastating. The rapid disruption to businesses around the world has left organizations and companies struggling to sustain business and security continuity. VHR takes a deeper look into how the pandemic has affected the Cyber Security sector and the changes that have had to be made in order to adapt to “new times”. Cyber Safe Home Working The boundaries imposed by governments in response to the COVID-19 pandemic have made employees manage their work from home. As a result, technology has become even more important in both our professional and personal lives. However, this eruption has caused an increase in both the probability and impact of cyberattacks. Ever since the beginning of the pandemic, the internet plays a huge role in making things simpler for people, allowing them to stay connected during periods of extended isolation and allowing people to manage their business online. Because of this, the nature of the threat changes to a great extent. Despite this increase in technology need, it is noticeable that a lot of organisation’s still do not present a cyber-safe remote-working environment to their employees. Hackers, nowadays, come up with new techniques to exploit new digital services and remote working setups. A rising number of online bad actors have initiated malware attacks on workers, healthcare facilities, and the unemployed. According to OpSec Security, some of the biggest targets of phishing were webmail sites and SaaS, accounting for around 34% of all attacks, trailed by 19% of financial institutions and 13% of the payment sector. However, this results in creating a lot of...
How to Build a GraphQL Server with Laravel GraphQL and Test It with Postman
GraphQL is a query language for your API. It simplifies the process of requesting the server by providing convenient ways to query objects. For instance, if you’re using a REST API and you need a list of books, you might hit the GET /books/list endpoint for all books. Then if you need a specific book by ID, you would hit GET /book?id={id}, which means you’ll be making multiple requests to the server. But GraphQL does something called declarative data fetching, where you can ask for what you want and get a predictable result in a single request. Awesome right? Let’s see how it all works. What we will be learning? In this article, you’ll learn the basics of GraphQL by using the Laravel GraphQL package to build a server that does the following: Before we get started, let’s go over some GraphQL fundamentals. What is a GraphQL Schema? A GraphQL schema describes queries, mutations, and types associated with it: In the code above, the exclamation mark on column names such as id, name, and email means that they are required fields. You can also define various data types such as Int, String, and so on. You can also include list types and define the data type it should contain like with hobbies. What are GraphQL Queries? GraphQL makes it convenient to interact with data on an object. You use methods to ask for specific fields on objects and then get the expected results: What are GraphQL Resolvers? Every time you request data from a GraphQL server, it gets resolved. Resolvers contain arguments such as an object, args, context, and...
12 Best Programming Languages for Web & App Development

Going further, let’s see different types of programming languages and their importance: Types of Programming Languages: Procedural Programming Language: The procedural programming language is useful to execute a sequence of statements that has certain output. It uses multiple variables, heavy loops, and other essential elements which separate them from functional programming languages. Functions of procedural programming can control variables while other functions return value. Functional...
Securing ASP.NET Core Razor Pages, Web APIs with Azure B2C external and Azure AD internal identities
This article shows how to implement an ASP.NET Core Razor page to authenticate against Azure B2C and use Web APIs from a second ASP.NET Core application which are also protected using Azure B2C App registrations. Azure B2C uses the signin, signup user flow and allows identities to authenticate using an Azure AD single tenant. Two APIs are implemented, one for users and one for administrators. Only identities from the Azure AD tenant can use the administrator API. The authorization implementation which forces this, is supported using an ASP.NET Core policy with a handler. Code: https://github.com/damienbod/azureb2c-fed-azuread Setup The ASP.NET Core applications only use Azure B2C to authenticate and authorize. An ASP.NET Core Razor page application is used for the UI, but this can be any SPA, Blazor app or whatever the preferred tech stack is. The APIs are implemented using ASP.NET Core and this uses Azure B2C to validate and authorize the access tokens. The application accepts two different access tokens from the same Azure B2C identity provider. Each API has a separate scope from the associating Azure App registration. The Admin API uses claims specific to the Azure AD identity to authorize only Azure AD internal users. Other identities cannot use this API and this needs to be validated. The Azure B2C identity provider federates to the Azure AD single tenant App registration. Setup Azure B2C App registrations Three Azure App registrations were created in Azure B2C to support the setup above. Two for the APIs and one for the UI. The API Azure App registrations are standard with just a scope definition. The scope access_as_user was exposed in...

Welcome back Mitul Makadia October 27, 2020 In the supply chain industry, rising customer expectations have given rise to larger product ranges, more complex logistics, and shamelessly fast lead times. All of this has led to soaring costs throughout the supply chain network. And minimizing the effect of these factors manually at each individual level is again a recipe for magnified operational costs. This is where Machine Learning in Supply Chain can help breathe a sigh of relief! Let’s explore how- Machine Learning in Supply Chain Integrating machine learning in supply chain management can help automate a number of mundane tasks and allow the enterprises to focus on more strategic and impactful business activities. Using intelligent machine learning software, supply chain managers can optimise inventory and find most suited suppliers to keep their business running efficiently.

As any self-respected developer, I redesigned my site many times. To be more precise, there were 6 significant redesigns. I thought it would be fun to document all these designs and see the evolution. In this review, I will focus mainly on the homepage. If you want to see all the screenshots of my site, you could visit the following links: Tech stacks I created this site back in 2016. The first site was built on my custom PHP-based CMS. After that, I moved to WordPress. At that time, static site generators became popular, and I was lucky to jump on that train. In 2017, I decided to switch to Hexo and Netlify. Hexo provided what I needed, but this year I moved my site (quite seamlessly) to Eleventy as I was reading about the excellent developer experience of the platform. I got to tell you, I could achieve so much more with Eleventy than with Hexo. The background Unfortunately, I don’t have any versions of the initial design. Since my site was relatively small, even the Wayback Machine site didn’t record it. The only thing I remember was that I wanted to develop my PHP-based drag-n-drop CMS. How young and optimistic was I, right? In 2017, I moved to WordPress briefly. I dropped out of the idea of making my own CMS and moved to the most famous player out there. However, I was never happy with it as I found it hard to develop and deploy new features. Sometime in the summer of 2017, I moved to Hexo. I loved the simplicity of it, the structure, the...
Building A Password Manager With React JS, Crypto JS, and Fauna – DEV Community
Building A Google Password Manager Clone With React JS and Fauna Authored in connection with the Write with Fauna program. This article will walk you through how I built a password manager with React JS and Fauna. Password managers are essential. When we have multiple accounts and multiple passwords, we need to keep track of them. Tracking passwords is difficult without having a password manager to help you. Prerequisites Getting Started With Fauna First, create an account with Fauna. Creating A Fauna Database To create a fauna database, head to the fauna dashboard. Next, click on the New Database button, enter the database name, and click enter. Creating Fauna Collections A collection is a grouping of documents(rows) with the same or a similar purpose. A collection acts similar to a table in a traditional SQL database. In the app we’re creating, we’ll have two collections, users and passwords. The user collection is where we’ll be storing our user data, while the passwords collection is where we’ll be keeping all the password data. To create these collections, click on the database you created, click New Collection. Enter only the collection name (users), then click save and do the same for the second collection (passwords).

Dearth of talent risky for cyber security
The dearth of trained cyber security professionals, in fact, has prompted a few institutes, including Jawaharlal Nehru Technological University, Hyderabad, to offer courses on cyber security Hyderabad: The cyber world is in a bit of turmoil of late. Cyber crooks are gaining an upper hand with an exponential rise in cybercrime threatening to disrupt normal life in multiple ways, even as law enforcement agencies struggle to find trained professionals to counter this all-pervading branch of crime. The dearth of trained cyber security professionals, in fact, has prompted a few institutes, including Jawaharlal Nehru Technological University, Hyderabad, to offer courses on cyber security. The University introduced B.Tech (CSE — Cyber Security), a full time four-year undergraduate course last year. Giving insight about why the University included this course, JNTU-H Rector Dr A Govardhan says there is no doubt that cybercrime is growing exponentially. “There is an urgent need to train young professionals. Although JNTU introduced B.Tech (CSE — Cyber Security) only last academic year, we have been conducting mandatory training for not just the CSE batch, but every stream of engineering. We also have an in-depth training programme for our faculty members. We also have introduced a first-of-its-kind online internship, where our students will be mentored by industry experts,” he said. Sandeep Mudalkar, CEO, Sytech Labs Pvt.Ltd, feels it is imperative that more workforce is employed to ensure cyber security. “The field is evolving, and thus there are new ways in which criminals are operating. Many a times, owing to their busy schedule, police personnel are not able to attend certain sessions. Those who are trained may or may not...
Step by Step – Repository Pattern and Unit of Work with Asp.Net Core 5 – DEV Community
In this article we will be exploring Unit of work and Repository pattern with EF Core and .Net 5. You can watch the full video on Youtube: Please find the source code on GitHub: https://github.com/mohamadlawand087/v33-repo-uow So what we will cover today: As always you will find the source code in the description down below. Please like, share and subscribe if you like the video. It will really help the channel What is a Repository Pattern The repository pattern is talked about a lot, especially in the API-and-microservice-heavy world that .net core shines in. The repository pattern is a strategy for abstracting data access layer. So what is a data layer? it is made up of the code in the application that is responsible of storing and retrieving the data. Adding, removing, updating, and selecting items from this collection is done through a series of straightforward methods, without the need to deal with database concerns like connections, commands, cursors, or readers. Using this pattern can help achieve loose coupling and can keep domain objects persistence ignorant. Why use Repository Pattern There are many reasons why we want to use code absatractions What is Unit of Work (UoW) If the Repository pattern is our abstraction over the idea of persistent storage, the Unit of Work (UoW) pattern is our abstraction over the idea of atomic operations. It will allow us to finally and fully decouple our service layer from the data layer. The unit of work pattern now manages the database states. Once all updates of the entities in a scope are completed, the tracked changes are played onto the database in...
10 Ways to Reduce Mobile App Development Costs
10 Ways to Reduce Mobile App Development Costs Any business pursues quite an obvious goal — to reduce mobile app development costs. The limited budget is one of the reasons why some customers refuse to develop a project, losing new business opportunities. However, since the product development process consists of several stages, you will be able to significantly reduce the time and money costs if you understand the features of each particular stage. In this article, we will talk about ways to reduce mobile app development costs without losing the coming product’s quality. 1. Make Detailed Requirements Specification Software engineers cannot read minds. Consequently, the more blurry the customer explains their requirements the more unpredictable the result may turn out in the end. Describe your project in detail: Based on a detailed project description, developers will evaluate implementation costs and development time much easier and answer customers’ other important questions. Want to start a project? Our team is ready to implement your ideas. Contact us now to discuss your roadmap! 2. Start with One Platform and MVP MVP (minimum viable product) is the product working prototype, using which it is possible to test market demand before a full-scale launch. The main goal of MVP is to test the software idea spending minimal cost. We can name Foursquare, Uber, and Snapchat among the well-known apps which started as MVP. It is better to spend a certain amount of money and understand that a specific idea or feature is not in demand than to spend ten times more money and then come to the same conclusions. The first version should have...
Cyber Security Today, Week in Review for May 14, 2021 | IT World Canada News
Welcome to Cyber Security Today. This is the Week in Review edition for the seven days ending Friday May 14th. I’m Howard Solomon, contributing reporter on cybersecurity for ITWorldCanada.com. In a few minutes guest commentator Dinah Davis, vice-president of research and development at managed service provider Arctic Wolf, will be with me to discuss what we think were notable events. But first some of the headlines from the past week: Outrage and worry erupted after one of the biggest gasoline pipelines in the U.S. was hit by ransomware. Colonial Pipeline decided out of an abundance of caution to shut its service, which provides fuel to almost half of the East Coast. Operations were restarted on Wednesday. Also on Wednesday President Biden signed an executive order to toughen cybersecurity in the federal sector. It removes barriers to cyber threat information sharing between American agencies and the private sector. It also orders federal departments to implement mandates multifactor authentication and use encryption to protect data. Ryerson University’s cybersecurity policy exchange called on the Canadian government to find ways of stopping misinformation, disinformation and fake news from being spread on private messaging services. These are services like Facebook Messenger, WhatsApp and Telegram. A report says many of these platforms are being used to spread hate, unwanted sexual comments and materials that incite violence. A student’s eagerness for free software led to a ransomware attack on a European biomolecular research institute. The student worked as an intern at the institute. They hunted the internet for a free version of a data visualization tool. What they got was an infected application that stole the...
What To Ask Your Web Developer / Designer – Dashal
I always tell people that finding a good web developer is like finding a good mechanic. Like with mechanics, you can get ripped off, and/or the work might not be up to par causing your website to need to be repaired or redone. Unfortunately, with having been a UX/UI designer and web developer for decades, I’ve seen it all. I have seen code that looks like it was written by someone who is five years old, websites that were incredibly overpriced only to have to be redone, and I have seen clients lose access to their website and not have true ownership of it. Your website is incredibly important. Not only is it something you will likely spend a good amount of money on, it is something that is most likely vital to your company’s revenue capabilities as well as an information hub for existing customers. Also, remember that your website is a reflection on you and your company. It’s often times a first impression. While it would be easiest to just hire Dashal, here are must-ask questions for a web developer or agency you are having design and develop your website. CMS (Content Management System) What content management system are they using? This is very important as you need the ability to update your own content. You never want to be in a position where you have to rely on other people. Most sites now use WordPress. While there are others, there is really no reason to use them as there isn’t anything that can’t be done in WordPress and it is so popular that should you need...
A Complete Tutorial to Learn Data Science with Python from Scratch
Introduction It happened few years back. After working on SAS for more than 5 years, I decided to move out of my comfort zone. Being a data scientist, my hunt for other useful tools was ON! Fortunately, it didn’t take me long to decide, Python was my appetizer. I always had a inclination towards coding. This was the time to do what I really loved. Code. Turned out, coding was so easy! I learned basics of Python within a week. And, since then, I’ve not only explored this language to the depth, but also have helped many other to learn this language. Python was originally a general purpose language. But, over the years, with strong community support, this language got dedicated library for data analysis and predictive modeling. Due to lack of resource on python for data science, I decided to create this tutorial to help many others to learn python faster. In this tutorial, we will take bite sized information about how to use Python for Data Analysis, chew it till we are comfortable and practice it at our own end.
