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...
