ZScaler: Achieving Zero Trust in Computer Networks

Following my previous post about the Zero Trust security model, I like to introduce ZScaler and also emphasize that implementing Zero Trust is not an easy feat, and it requires a comprehensive approach that involves people, processes, and technology. ZScaler is a cloud-based security solution that has been designed to help organizations achieve Zero Trust in their computer networks.

ZScaler is a cloud-native security platform that provides secure access to the internet and internal applications. ZScaler uses a Zero Trust architecture that assumes no user or device is trustworthy, and all network traffic must be inspected and verified before being allowed access. ZScaler achieves Zero Trust through its comprehensive security features, which include:

  1. Multi-factor authentication: ZScaler provides a multi-factor authentication (MFA) solution that ensures that only authorized users can access corporate resources. The MFA solution supports various authentication methods, including SMS, email, and mobile apps.
  2. Network segmentation: ZScaler segments the network into multiple zones and enforces access control policies based on the principle of least privilege. This approach limits the attack surface and prevents lateral movement within the network.
  3. Secure access service edge (SASE): ZScaler provides a SASE solution that delivers security and networking capabilities as a cloud service. SASE consolidates networking and security functions, making it easier for organizations to manage and secure their network infrastructure.
  4. Real-time monitoring and analytics: ZScaler provides real-time monitoring and analytics to detect and respond to any suspicious activity or anomalies. This approach helps organizations identify and mitigate potential threats before they cause significant damage.
  5. Encryption: ZScaler provides end-to-end encryption for all network traffic, ensuring that data is protected in transit. Encryption also prevents eavesdropping and man-in-the-middle attacks.

ZScaler’s Zero Trust architecture is based on the principle of “never trust, always verify.” ZScaler ensures that all network traffic is inspected and verified, regardless of its source or destination. This approach reduces the attack surface and limits the impact of a potential breach.

Implementing Zero Trust is not easy, and it requires a comprehensive approach that involves people, processes, and technology. ZScaler’s cloud-native security platform provides a comprehensive solution that helps organizations achieve Zero Trust in their computer networks. With ZScaler, organizations can be assured that their network infrastructure is secure, and their critical assets are protected.

Zero Trust: The Future of Network Security

In today’s ever-evolving technological landscape, cyber threats have become a common problem for organizations worldwide. With the rise of remote work and cloud computing, traditional perimeter-based security models are becoming increasingly inadequate. The Zero Trust security model is a new approach that addresses these shortcomings and offers a more robust and effective solution for securing computer networks.

The concept of Zero Trust was first introduced by John Kindervag, a former analyst at Forrester Research, in 2010. Zero Trust is a security model based on the principle of “never trust, always verify.” In other words, it assumes that no user or device is trustworthy, regardless of whether they are inside or outside the organization’s network. Every user, device, and network connection must be authenticated, authorized, and verified before being granted access to any resource.

The Zero Trust security model is designed to address the limitations of traditional perimeter-based security models. Perimeter-based security assumes that everything inside the network is trusted and everything outside is not. However, this model is no longer adequate because users are now accessing corporate resources from various locations, devices, and networks, making it difficult to establish a clear perimeter.

Zero Trust, on the other hand, assumes that the network has already been breached or will be breached at some point. Therefore, every device and user must be continuously authenticated and verified before being granted access to any resource. This approach reduces the attack surface and limits the impact of a potential breach.

The Zero Trust security model is based on five core principles:

  1. Verify and authenticate every user and device before granting access to any resource.
  2. Limit access based on the principle of least privilege, which means giving users access only to the resources they need to perform their job.
  3. Assume that all networks, whether internal or external, are untrusted.
  4. Monitor and log all network activity to detect and respond to any suspicious behavior or anomalies.
  5. Apply security policies consistently across all devices, networks, and applications.

Implementing a Zero Trust security model requires a comprehensive approach that involves people, processes, and technology. Organizations need to identify all their assets, map out their network topology, and assess their risk posture. They need to implement multi-factor authentication, network segmentation, and access controls based on the principle of least privilege. They also need to monitor and log all network activity, use encryption and apply security policies consistently across all devices, networks, and applications.

In conclusion, the Zero Trust security model is a new approach that offers a more robust and effective solution for securing computer networks. By assuming that no user or device is trustworthy, it reduces the attack surface and limits the impact of a potential breach. Organizations that adopt Zero Trust will be better equipped to defend against cyber threats and protect their critical assets.

Web Assembly: The Future of Web Development

Web development has come a long way since the early days of static HTML pages. Today, web applications are becoming increasingly complex, and users expect fast and responsive experiences. With the rise of web technologies like JavaScript and HTML5, developers have been able to create rich web applications that rival traditional desktop software. However, even with these advancements, web applications can still suffer from performance issues.

Enter Web Assembly (WASM), a new technology that promises to revolutionize web development by offering near-native performance for web applications. In this blog post, we’ll look at what Web Assembly is, how it works, and why it’s being touted as the future of web development.

What is Web Assembly?

Web Assembly is a binary format for executing code on the web. It was first introduced by Mozilla in 2015, and it has since gained support from all major browsers, including Google Chrome, Microsoft Edge, and Safari. Web Assembly allows developers to write code in languages other than JavaScript, such as C++, Rust, and Go, and run that code directly in the browser.

How does Web Assembly work?

Web Assembly code is compiled from a higher-level programming language into a binary format that can be executed by the browser. This means that developers can write code in their language of choice, compile it to Web Assembly, and then run that code in the browser without the need for an interpreter or virtual machine.

Because Web Assembly is designed to be platform-agnostic, it can run on any device with a compatible browser, including smartphones, tablets, and desktop computers. This makes it a powerful tool for creating cross-platform applications that work seamlessly across all devices.

Why is Web Assembly the future of web development?

Web Assembly offers several advantages over traditional web development technologies like JavaScript. Here are some of the key reasons why it’s being touted as the future of web development:

  1. Performance: Web Assembly offers near-native performance for web applications, which means that applications can run faster and more efficiently than ever before. This is particularly important for applications that require a lot of processing power, such as games and video editing software.
  2. Language choice: With Web Assembly, developers can choose the programming language that best suits their needs, rather than being limited to JavaScript. This can lead to more efficient and maintainable code, as well as a larger pool of developers who can contribute to the project.
  3. Cross-platform compatibility: Because Web Assembly can run on any device with a compatible browser, it’s a powerful tool for creating cross-platform applications that work seamlessly across all devices.
  4. Security: Web Assembly provides a sandboxed execution environment that isolates code from the rest of the system. This makes it more difficult for attackers to exploit vulnerabilities in the code and compromise the security of the application.
  5. Accessibility: Because Web Assembly is designed to be platform-agnostic, it can run on a wide variety of devices, including those with low processing power or limited memory. This makes it more accessible to users who may not have access to high-end hardware.

Web Assembly is a game-changer for web development, offering near-native performance and cross-platform compatibility that was previously impossible with traditional web technologies. While it’s still a relatively new technology, it’s quickly gaining traction among developers who are looking for ways to build faster and more efficient web applications. As more developers begin to adopt Web Assembly, we can expect to see a new generation of web applications that are faster, more responsive, and more accessible than ever before.

Social Robots in Education: A Promising Tool for Students with Learning Disabilities

Technology has become an essential part of our daily lives, and it has also made significant inroads into education. With the help of artificial intelligence and machine learning, educators have been exploring new ways to enhance learning for students with disabilities. In a recent study conducted by the University of Waterloo and the Learning Disabilities Society in Vancouver, social robots have been found to be a promising tool for students with learning disabilities.

The study, led by Dr. Kerstin Dautenhahn, a professor of electrical and computer engineering, involved testing a small humanoid robot called QT on 16 students with learning disabilities. The researchers divided the students into two groups. In one group, students worked one-on-one with an instructor only. In the other group, the students worked one-on-one with an instructor and a QT robot.

The robot’s ability to perform gestures using its head and hands, accompanied by its speech and facial features, makes it very suitable for use with children with learning disabilities. The robot was controlled by the instructor using a tablet, which directed the robot to autonomously perform various activities using its speech and gestures. The instructor triggered the robot to lead the student, who introduced the session, set goals, and provided self-regulating strategies if necessary.

The robot also used strategies such as games, riddles, jokes, breathing exercises, and physical movements to redirect the student back to the task if the learning process was getting off-track. Students who worked with the robot were “generally more engaged with their tasks and could complete their tasks at a higher rate compared” to the students who weren’t assisted by a robot.

The researchers concluded that the use of robots in public education systems has great potential, and the findings imply that robots have a positive effect on students. Dr. Dautenhahn has been working on robotics in the context of disability for many years and incorporates principles of equity, inclusion, and diversity in research projects.

While most research on the use of social robots in education has focused on children with Autism Spectrum Disorder, little work has been done on the use of socially assistive robots for students with learning disabilities. The researchers plan to conduct further studies using the QT robot and explore its potential for enhancing learning for students with disabilities.

In conclusion, social robots have the potential to revolutionize the way we approach education for students with learning disabilities. By providing additional learning support, such as one-on-one instruction, and using the latest technology, such as social robots, educators can create a more engaging and effective learning experience for students with disabilities. With further research and development, social robots could become a valuable tool in the classroom, helping students with disabilities achieve their full potential.

Control Azure cost using PowerBI

Recently we decided to have a look at our Azure costs and rationalize what was costing us our hard-earned dollars each month. Having around 800 staff with some of them creating Azure resources for development purposes and forgetting to stop/remove them when they were not needed was a string reason to get the cost under control. If your organization is big with lots of people being able to create Azure resources, it is recommended that you start looking at Azure policies. The purpose of Azure policies is to restrict what the users in the organizations can create. One example would be to limit the VM sizes users can create to the sizes you can afford. You can read about Azure policies here.

Coming back to the topic of keeping an eye on your day to day Azure costs, there is a very handy service in PowerBI you can utilize. The steps are very simple:

 

1- Log in to PowerBI website or launch PowerBI desktop (downloadable from here)

2- Click on Get Data and then under Services click on Get 

 

AzureCostPowerBI1

3- From the list of apps that appear, find “Microsoft Enterprise Azure” and click on “Get it now. A new window opens and asks you to identify your environment:

 

AzureCostPowerBI2

4- To retrieve your Enrollment Number you need to log in to your enterprise portal accessible at https://ea.azure.com. Once you logged in the number is displayed at the top of the screen:

AzureCostPowerBI3

5- For Environment URL provide “https://ea.azure.com” and for the number of months provide a number (I could not personally get more that 6 month’s worth of consumption data).

6- That’s it! You will be taken to a dashboard created by PowerBI giving you a lot of information.

 

P.S: This is not a PowerBI guide but one feature that I particularly like is the QA feature. Once your usage data is loaded into PowerBI, you can use natural language to query your usage and PowerBI will show a Chart, a number, a table or a string based on the nature of your query. For instance, I was interested to know what resource group was costing us the most so I typed a query like: “cost of last month by resource group” and was represented with a chart like this. Easy! I’ll let you take your imagination and take this further.

AzureCostPowerBI4

P.S #2: Another feature that I particularly liked was the ability to monitor a data field inside PowerBI, and what better metric to monitor than the cost itself! My idea was to set up an alert on yesterday’s cost and see if has spiked to an amount that requires intervention! This was to not let it run until the end of them month and create a bill shock but rather send an email so something can be done. This was achieved by clicking on the cost tile on the dashboard and creating an alert for the data field:

AzureCostPowerBI5

 

There was a small problem with the data coming from Azure and yesterday’s cost was not synced and the amount was lower than I expected. What I did was changed it to the cost of two day’s ago by editing the tile.
