Let’s get one thing straight — legacy technology isn’t bad.
Legacy computer systems and software have withstood the test of time for a reason: they get the job done consistently, predictably, and reliably.
Many executives run operations from a “if it ain’t broke, don’t fix it” framework. Why spend money replacing something that works just fine?
The problem is when leadership is under the illusion that things are fine when the house is about to burn down. Unfortunately, unplanned legacy breakdowns often lead to costly downtime, logistical complications, and disgruntled customers.
As mounting server hacks have shown, perimeter-based networks are particularly vulnerable to data breaches. In this article, we’ll look at an industry that could have benefited from reducing its dependency on legacy technology sooner rather than later. We’ll also review the top four things organizations should do to approach Zero Trust implementations most pragmatically.
Why Switch from Legacy Tech to Zero Trust
In 2016, Southwest Airlines experienced that moment after a single router failure delayed hundreds of thousands of fliers. The airline’s monolithic architecture couldn’t adapt quickly enough to accommodate large fluctuations in the environment.
As reported by USA Today, Southwest’s CEO expected the incident to cost the company up to $10 million. But Southwest isn’t the only airline experiencing IT growing pains.
According to The Wall Street Journal, several U.S. airlines have felt the weight of aging legacy systems in recent years. The infrastructures simply aren’t designed to handle high-server traffic, attempted hacks, and remote work policies.
Security researcher Noam Rotem further exposed the travel industry’s technology shortcomings after hacking into Amadeus in 2019. The travel reservation system contained a significant security breach that allowed anyone to access and change private information on bookings.
Considering the system’s integration with 200 airlines, the security oversight left vulnerable the private information of millions of passengers!
