Business email compromise (BEC) is the most expensive form of online fraud encountered every year, with international losses in excess of $26 billion over the past three years, according to the FBI.

Over the past days and weeks, more and more organisations have switched to digital products and services to sustain working from home, to keep productivity up and to be connected.

We need a secure and trustable infrastructure. We need to be able to provide assurance that the service we are contacting is genuine, that the transaction is secured from eavesdroppers, and that we leave no useful traces behind us. Why has our public key certificate system failed the Internet so badly? —Geoff Huston

The survey’s respondents cited all the usual benefits to working at home — including flexibility (53%), lack of a commute (38%), reduced stress (32%), and reduced office politics (18%). —David Cassel

Kea stores each type of information independently. If you prefer your server installation to be small, you can use memfile — our most compact and simplest configuration and generally the fastest to use. Your configuration will be stored in a JSON file on disk and will contain host reservations; the lease information will be stored on a local disk in a plain-text CSV file. —Tomek Mrugalski
