Zero Trust Security Security for the Cloud-Native Era By Amir Sharif, Co-founder at Aporeto <strong>Cyber</strong>crime on the Rise Every day, hackers succeed at gaining access to the well-protected systems. Adversaries are more skilled and better funded than ever, and traditional security measures are ineffective. In 2018, cybercrime cost the global economy an estimated $600 billion – about 0.8 percent of global GDP. Security, previously an afterthought in the world of cloud-native applications, has come to the forefront with this barrage of data breaches that highlight critical flaws with legacy data center security systems. These flaws? In a word (or two): IP addresses, and IP-based security. In the cloud-native era “location” is no longer bound to a single data center; using IP address as a proxy for identity in an attempt to secure applications becomes a fool's errand. Castles and Moats While most data centers are virtualized, they operate with the assumption that what is inside the firewall can be trusted, and what is outside cannot. This is also referred to as the “castle-and-moat” mentality, which focuses on the defense of the perimeters and turns a blind eye to anything already inside the castle walls (presuming they have previously been cleared for access). This highlights a key failing of firewalls and traditional perimeter security at large. If a malicious presence manages to gain access to the infrastructure, it can easily begin both north/south and lateral attacks and wreak havoc before its presence is even questioned. Despite its present-day failings, this was an acceptable approach to security when applications were monolithic or had a classic three-tier architecture. With the dawn of the cloud-native era, however, applications have become disaggregated across public and private cloud, and using IP addresses to secure applications becomes risky business. Broad adoption of both mobile and cloud technology has begun to erase the data center perimeter. (One way to visualize this is as your handheld devices as 60
miniature bridges - an email can cross the defensive moat between the corporate IT infrastructure and your personal cloud in mere nanoseconds). Zero Trust Fundamentals: Trust No-one To secure a cloud-native application, we must embrace Zero Trust security and expand our thinking beyond legacy solutions to evolve with new application architectures. Application security must be thought of in terms of authentication and authorization: trust no-one, and authenticate, authorize and encrypt everything. These are the key tenets of Zero Trust security. Eliminate network trust Segment network access Gain visibility and analysis capabilities Trust No-one Zero Trust as a concept establishes a security paradigm based on the assumption that any system can be accessed and breached at any time, by anybody. You must trust no-one: even those already inside the network perimeter. You can apply this to any structure - a cloud application, a data center, a bank vault, the aforementioned castle-and-moat, or your own home. Building security controls from a basis of Zero Trust allows you to keep data, property, confidential information (or even your family) safe. Assigning Dynamic Workload Identity Traditional approaches to security are two dimensional: based on IP address, and therefore, location. True application identity must be formed using a multi-dimensional trust profile. Consider approaching an application as you would a person, or a colleague: you automatically generate a dynamic trust profile based on their face, mannerisms, gait, height, voice, and other identifiers that – collectively – are unique to them. This same dynamic approach must be taken to confirming application-identity and must be assigned at a granular, workload level. 61
