Why Is Professional Development Important?

Learning is a lifelong process, and it never stops. Of course, no one is born to be brilliant at their job, but we learn and work on our development goals. After all, it takes time and effort to learn new skills and apply new knowledge. 

Thanks to the fierce competition, everyone is focused on their professional development to stay ahead. Here is everything you need to know about why is professional development important. 

Professional Development Explained

Before we understand why it’s important, you need to understand what professional development is. The term refers to career training and continuing education after an individual starts working to develop new skills for advancement in their career. Many jobs out there require individuals to take continuing education. 

However, professional development is not just limited to education. It refers to all the training and learning opportunities you can take to enhance your work and skills. These skills are used to advance in the career. 

Why Is Professional Development Important?

Here are the many reasons why professional development tools are important for any organization:

1. Increases Employee Retention 

As an organization, you can offer professional development opportunities to increase employee retention. It Continue reading

Cross Site Scripting is the second most prevalent issue in the Open Source Foundation for Application Security (OWASP) top 10 – it’s found in roughly 2/3 of all applications.


Unidentified threat actors are actively exploiting a critical authentication bypass vulnerability to hijack home routers as part of an effort to co-opt them to a Mirai-variant botnet used for carrying out DDoS attacks, merely two days after its public disclosure.


Big O notation is an important tools for computer scientists to analyze the cost of an algorithm. Most software engineers should have an understanding of it.


Cybersecurity researchers have disclosed a new class of vulnerabilities impacting major DNS-as-a-Service (DNSaaS) providers that could allow attackers to exfiltrate sensitive information from corporate networks.


In his keynote, Tait, former information security specialist for the UK’s GCHQ and more recently a member of Google’s Project Zero team, outlined what he considers the three main factors that drove high-profile cyberattacks on Colonial Pipeline, Kaseya, Exchange Server, SolarWinds, and Codecov, as well as North Korea’s targeting of security researchers and the NSO Pegasus Project iOS hacks.


The two researchers reported the issues to Apple and many of them have been fixed. However, the security weaknesses are not Continue reading

The Mystery of Known Issues

I’ve spent the better part of the last month fighting a transient issue with my home ISP. I thought I had it figure out after a hardware failure at the connection point but it crept back up after I got back from my Philmont trip. I spent a lot of energy upgrading my home equipment firmware and charting the seemingly random timing of the issue. I also called the technical support line and carefully explained what I was seeing and what had been done to work on the problem already.

The responses usually ranged from confused reactions to attempts to reset my cable modem, which never worked. It took several phone calls and lots of repeated explanations before I finally got a different answer from a technician. It turns out there was a known issue with the modem hardware! It’s something they’ve been working on for a few weeks and they’re not entirely sure what the ultimate fix is going to be. So for now I’m going to have to endure the daily resets. But at least I know I’m not going crazy!

Issues for Days

Known issues are a way of life in technology. If you’ve worked with any Continue reading

Data protection controls with Cloudflare Browser Isolation

Data protection controls with Cloudflare Browser Isolation
Data protection controls with Cloudflare Browser Isolation

Starting today, your team can use Cloudflare’s Browser Isolation service to protect sensitive data inside the web browser. Administrators can define Zero Trust policies to control who can copy, paste, and print data in any web based application.

In March 2021, for Security Week, we announced the general availability of Cloudflare Browser Isolation as an add-on within the Cloudflare for Teams suite of Zero Trust application access and browsing services. Browser Isolation protects users from browser-borne malware and zero-day threats by shifting the risk of executing untrusted website code from their local browser to a secure browser hosted on our edge.

And currently, we’re democratizing browser isolation for any business by including it with our Teams Enterprise Plan at no additional charge.1

A different approach to zero trust browsing

Web browsers, the same tool that connects users to critical business applications, is one of the most common attack vectors and hardest to control.

Browsers started as simple tools intended to share academic documents over the Internet and over time have become sophisticated platforms that replaced virtually every desktop application in the workplace. The dominance of web-based applications in the workplace has created a challenge for security teams who Continue reading

Attack that defeats AMD chip security possible, unlikely

AMD likes to crow about how its Epyc server processors can encrypt the content of virtal machines while they’re in operation so they are secure and isolated, preventing other VMs on the processor from accessing the encrypted contents.Well, researchers from the Technical University of Berlin have found a weakness in that feature, known as Secure Encrypted Virtualization (SEV), and published a theoretical attack that defeats the protection.The paper ”One Glitch to Rule Them All: Fault Injection Attacks Against AMD’s Secure Encrypted Virtualization” details how the researchers succeeded in mounting a voltage fault-injection attack.To read this article in full, please click here

Announcing Tenant Control in Cloudflare Gateway

Announcing Tenant Control in Cloudflare Gateway

The tools we use at work are starting to look like the apps we use in our personal lives. We send emails for our jobs using Google Workspace and respond to personal notes in Gmail. We download PDFs from our team’s Dropbox and then upload images to our personal account. This can lead to confusion and mistakes—made worse by remote work when we forget to log off for the day.

Today, we’re excited to announce Tenant Control in Cloudflare Gateway, a new feature that helps keep our work at work. Organizations can deploy Cloudflare Gateway to their corporate devices and apply rules ensuring that employees can only log in to the corporate version of the tools they need. Now, teams can prevent users from logging in to the wrong instance of popular applications. What’s more, they can make sure corporate data stays within corporate accounts.

Controlling the application, alone, isn’t sufficient

Cloudflare Gateway provides security from threats on the Internet by sending all traffic leaving a device to Cloudflare’s network where it can be filtered. Organizations send traffic to Cloudflare by deploying the WARP agent, a WireGuard-based client built on feedback from our popular consumer app.

There was a discussion in a working group session at the recent IETF 111 meeting over a proposal that the working group should require at least two implementations of a draft before the working group would consider the document ready. What's going on here?

kOps adds support for Calico’s eBPF data plane

Kubernetes operations (kOps) is one of the official Kubernetes (K8s) projects. The kOps project allows for rapid deployment of production-grade K8s clusters in multiple cloud platforms. By leveraging yaml manifests, kOps delivers a familiar experience to users who have worked with kubectl. Similar to K8s clusters in popular cloud platforms, kOps helps set up self-managed clusters to easily deliver high availability. Given its ease of use, it is a very popular choice when users want to deploy self-hosted Kubernetes clusters.

With the recent release of kOps (v1.19), support for the Calico eBPF data plane was added to the utility. In addition to the above-mentioned features, the latest kOps update offers an effortless way to autodeploy K8s clusters utilizing Project Calico for networking and the Calico eBPF data plane. Calico eBPF data plane implementation replaces kube-proxy and delivers equivalent functionality; it also leverages the most optimal datapath for traffic. These changes deliver a network performance boost and source IP preservation to your cluster.

In this blog post, we will showcase the steps required to deploy a cluster that utilizes these newly available features.

What is eBPF?

eBPF is a virtual machine embedded within the Linux kernel. Continue reading
