How Zero Trust Secure Access Helps Mitigate Common IIoT Security Risks
Over the 20 years since the introduction of the “Secure Socket Layer” (SSL) by Netscape, its descendants have become the security standard for all web browsers and much else. The original SSL protocols were soon built upon by the IETF into the non-proprietary “Transport Layer Security” (TLS) protocols, but many people use the term “SSL” to refer to mean either SSL or TLS. Indeed, the latest version of SSL (SSL 3) has now officially been deprecated and should rarely if ever be seen in practice, due to security issues. SSL/TLS is a network protocol that secures data communication between servers and clients via a combination of asymmetric and symmetric cryptography. It is most commonly used together with HTTP (where the client and web server are a web browser) however it is also to be found in other protocols, including SMTP where it can be used to encrypt mail as it is sent between mail relays.

Before the advent of Cloud and BYOD, enterprise network access was predominantly restricted to few limited corporate owned devices where network admins had full control and visibility into endpoints. The phenomenon of digital IT has led enterprises to embrace initiatives like Cloud and BYOD, allowing users to use personal devices for corporate network access anytime and from anywhere. This also opened the floodgates for more security loopholes, increasing the number of breaches and targeting access security. The amount of money spent on recovering from a breach is far higher than what is spent on planning and implementing security infrastructures.

We are defined by the company we keep – but what do we mean by the word “community?” The word “community” used to refer to the simple idea of a group of people living in the same place. And the idea of “Communication” is about the way we share information around our community. But in today’s virtual world, we live in multiple online places: at work, with friends, sports, shopping, and more. Technology means that we can inhabit all these communities simultaneously, and it is easy to create new watering holes for communities to interact.
But what makes a community grow? Why do communities gather around one watering hole rather than another? Think of the number of messaging apps out there – I just counted EIGHT messaging applications on my phone. And that doesn’t include LinkedIn, Outlook, Strava, Garmin, Facebook and all the other applications that compete for my attention.
