FBI warning on ransomware, how the pandemic has affected IT security and a new botnet threat. Welcome to Cyber Security Today. It’s Wednesday March 17. I’m Howard Solomon, contributing reporter on cybersecurity for ITWorldCanada.com. The FBI has issued a flash alert, warning of increased ransomware attacks on schools, colleges, seminaries and universities in the United States and the U.K. The gang behind this string of attacks will copy data from the institutions before encrypting all files. Then it uses the copied files to squeeze the victim organization into paying for a decryption key. If not the data will be sold to criminals. Usually the gang gets into organizations by getting passwords for remote access systems or by getting people to fall for phishing emails with infected attachments. The FBI reminds all organizations of the importance of patching, using multifactor authentication to protect logins to computer networks and disabling unused remote access ports. The pandemic has forced a large number of people who use computers to work from home. A new survey of IT security decision-makers for Randori suggests firms that were unprepared had a lot of headaches. Forty-two per cent of respondents said their organizations were compromised because of unapproved or unsecured computers and smartphones connected to the network. Three-quarters said cyber attacks have increased in the past year. Just over half agreed protecting their organization from online attacks has become more difficult. One of the big problems is people who work from home don’t have the IT protection that enterprise-grade security systems provide from their offices. Seventy-six per cent of respondents said prioritizing which applications to patch has...
We have earlier discussed In this tutorial, we will learn about NVM & process to install NVM on Linux. NVM stands for Node version manager & as you might have guessed with name, it’s used to control Nodejs versions installed on our system. It is a command line utility, which allows us to use & switch between multiple versions of Nodejs. It works on Linux & MacOS but does not yet support Windows machines, but there are some other 3rd party tools for Windows to do the same job. Install NVM on Linux The process to install NVM on Linux is simple & same whether you are using Ubuntu or CentOS/RHEL. Firstly we need to download the install script for NVM & run it. Download & execute the install script by running the following command from terminal, $ curl -o https://raw.githubusercontent.com/creationix/nvm/v0.33.6/install.sh | bash Once the script has been executed without any errors, we need to source our .bash_profile for immediately affect the changes made, $ source ~/.bash_profile Now we are ready to use NVM for installing the various versions of Node.JS on our systems. To check & list all the available Node.JS versions, run the following command from the terminal, $ nvm list-remote This would produce the list of all available versions of Node.JS & output will look something like this, We can then choose a version & install it using NVM. Let’s suppose we need to install versions, v0.12.11 & v8.1.3, install them using the following command, $ nvm install v0.12.11 $ nvm install v8.1.3 After installation, we can also set a default version which will start by...
So you want to become a web developer? Well then it’s time to put down that “Learn Super Duper Language v8.3 in 24 hours” book. Instead, make it a habit to ask yourself these 10 questions every day. Is there a pattern here? Looking for patterns in what works and what doesn’t work leads to discovering the underlying principles that drive seemingly unrelated concepts and behaviours. To get a deeper understanding of the work that you do make it a habit of asking yourself “Is there a pattern here?”. This applies to more than just your code. Is there a pattern in the types of changes requested by business? Is there a pattern in the way technologies evolve? Are you seeing the same types of bugs popping up again and again? To understand is to perceive patterns – Isaiah Berlin How can I make this simpler? Often as web developers we want to produce complex and scalable solutions. Making something tremendously complex makes you feel like the master of your universe. The problem is that you will never be able to predict how your product and business is going to change in the future. “Architecture” and coding is much more like gardening than architecture. You need to be able to adapt to an ever changing environment. The more complex your solution the more difficult this becomes. Simplicity is the ultimate sophistication. – Leonardo da Vinci Why does it work like that? Knowing that something works and knowing why it works that way are two very different things. If you know why something behaves the way it does you are able...
I’ve always been fascinated by making apps as small as possible, especially in the .NET space. No need to ship any files – or methods – that you don’t need, right? I’ve blogged about optimizations you can make in your Dockerfiles to make your .NET containerized apps small, as well as using the ILLInk.Tasks linker from Mono to “tree trim” your apps to be as small as they can be. Work is on going, but with .NET Core 3.0 preview 6, ILLink.Tasks is no longer supported and instead the Tree Trimming feature is built into .NET Core directly. Here is a .NET Core 3.0 Hello World app. Now I’ll open the csproj and add PublishTrimmed = true. <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>netcoreapp3.0</TargetFramework> <PublishTrimmed>true</PublishTrimmed> </PropertyGroup></Project> And I will compile and publish it for Win-x64, my chosen target. dotnet publish -r win-x64 -c release Now it’s just 64 files and 28 megs! If your app uses reflection you can let the Tree Trimmer know by telling the project system about your Assembly, or even specific Types or Methods you don’t want trimmed away. <ItemGroup> <TrimmerRootAssembly Include="System.IO.FileSystem" /></ItemGroup> The intent in the future is to have .NET be able to create a single small executable that includes everything you need. In my case I’d get “supersmallapp.exe” with no dependencies. Until then, there’s a cool global utility called Warp. This utility, combined with the .NET Core 3.0 SDK’s now-built-in Tree Trimmer creates a 13 meg single executable that includes everything it needs to run. C:\Users\scott\Desktop\SuperSmallApp>dotnet warpRunning Publish...Running Pack...Saved binary to "SuperSmallApp.exe" And the result is just a 13 meg single EXE ready to...
For the last few years, millions of people worldwide have been using mobile devices as the main source of accessing the internet. For this reason, many industries developed a mobile app for their businesses. During the last few years, the IT industry mainly concentrated on fulfilling the market demand and their businesses were focused on making a market existence. However, they ignored to concentrate on app security, code quality, maintainability, and development costs. Now, this is high time to concentrate on such problems and accept new techniques to enhance quality and reduce risks. In this post, I have come up with the approach of DevOps in mobile app development, its benefits, challenges it faces, and how you can implement it in your app development project. So, let’s get started! What is DevOps? DevOps is an exclusive methodology that highlights effective cooperation among all stakeholders engaged in producing a digital product. It incorporates operation staff members, app developers, and project managers. Although the conventional strategies and approach to software development caused extra development costs, time, and client dissatisfaction, DevOps reduces the gap between operations and development and wins over the challenges related to constant software development. The concept behind DevOps for mobile app development is to support a culture of cooperation between teams that earlier worked individually. DevOps is not solely an approach; it can be mainly considered a state of mind or culture. It causes a shift in the mindset, promotes deeper integration, and enhances cooperation. DevOps brings automation, constant delivery, and agile together so that operation and development teams can be more productive and launch software more dependably...
