What COVID-19 Has to Do With Network Security
The Coronavirus has been the top celebrity of the year 2020. The world was and is fighting this pandemic and travel limitations are widely used in order to control the spread of the disease. While some say these restrictions are critical, others claim them to be ineffective and redundant. I am not an epidemiologist and will leave that analysis to the experts. I am, however, a software architect and cannot resist comparing travel restrictions to one of the most common ways of securing network architectures – Micro-segmentation.
In many ways, software malware and biological viruses are similar (that is why they are called computer viruses) - both try to spread in a network and infect as many subjects as they can. If we accept this simple analogy, micro-segmentation can make a lot of sense; it is the equivalent of banning incoming flights from China, and it is aimed at making sure that if some part of the organization is affected, the infection cannot spread to other parts of the organization.
