Get ready for self-driving banks
This article from the Financial Times looks at the algorithms and blockchain technology that may be required for 21st century regulation. DeFi turns all this on its head. It leverages blockchain technology to deliver services with no human intermediation. One example is creating money markets with algorithmically derived interest rates based on supply and demand — rates that traditional banks set by committee. Other DeFi projects include decentralised exchanges that allow users to trade without brokers, and protocols for lending that do not involve loan officers or credit committees. Although these “self-driving banks” are new, they are not small. They are likely to be mainstream before self-driving cars start to…

Clubhouse App…the new “Drop-In Audio Chat” App Lighting Up the Tech Community…
I was able to start a Clubhouse account over the New Year weekend. Clubhouse is a new type of social product based on voice. The app that bills itself as a “Drop-in audio chat” social network. It allows people everywhere to talk, tell stories, develop ideas, deepen friendships, and meet interesting new people around the world.

What is Multi-Factor Authentication and Why is It Necessary?
Many people have heard the basics of account protection: Get a password manager for your online accounts, make your passwords complex and never reuse them. But what about Multi-Factor Authentication? What is Multi-Factory authentication, what’s so special about it, and why is it needed? Multi-Factor Authentication (MFA), also sometimes known as Two-Factor Authentication (2FA), adds another layer of security to the sign-in process giving accounts further protection against unauthorized access. MFA requires multiple (two or more elements) to be used in order to grant full authentication. Multifactor authentication consists of 3 major things: Something you know: This can be a password, or the answer to a security question that cannot…

WSJ–“Companies Urged to Adjust Hiring Requirements for Cyber Jobs”…
News of the current shortage of cybersecurity professionals and the demand needed in the coming years to fill roles is seemingly ubiquitous these days. There’s an interesting article in the WSJ on the correlation between the shortage of cybersecurity capable applicants available and the job requirements being posted by hiring companies & HR departments. Despite holding a doctorate in computer science and having extensive military, federal and private-sector experience, Mr. Cunningham said he is routinely approached by companies offering entry-level positions. Job postings on social-media websites for positions usually regarded as gateway roles are rife with such requirements. For instance, one post on recruiting site Glassdoor for a security operations…

LinkedIn Learning Path–Comp TIA A+ and Network + Courses…
I just finished the LinkedIn Learning Path–Comp TIA Network+ course and had previously finished the Comp TIA A+ course last month. While looking at the dates it seems I’ve been doing this for the past month-and-a-half when the courses say they take about 56 hours combined to complete, I really committed to carefully following each video–stopping, starting, pausing, and rewatching them–to really understand the concepts, while taking notes of course. Both of these courses are currently being offered for free through a Microsoft/LinkedIn pandemic education relief initiative that I had previously written about. Having completed them both I can say that I do think they are very beneficial and I…

Integrating Security Into Networking From The Ground Up…
This industry insight article from GCN discusses how moving forward, the convergence of security and networking will be needed to work together from an integrated perspective. As more of the workforce continues remote-work, the potential for attacks/threats/malicious actors increases and heightened security will continue to be of critical importance. Secure access service edge (SASE) and software-defined wide-area network (SD-WAN) technologies are designed to merge security and networking into a single, integrated solution that can rapidly and easily scale and adapt to expanding environments and requirements. These forward-leaning capabilities help agencies better plan for the future while ensuring security remains a top priority even amid ongoing changes. Traditional security solutions no…
