Bad actors are making sure that healthcare organizations either spend now on security defenses or pay later for ransoms, fines and lawsuits.
Geopolitical uncertainty has dramatically increased the chances that healthcare organizations will experience more security attacks in the next couple years. Specifically, SecOps teams need to prepare for even more ransomware attacks to extort money along with “lights out attacks” designed to cripple day to day operations.
The last two years have proven that the statement, “No one would want to hurt a hospital or healthcare clinic,” is a false narrative. Cyberattacks against network servers in the healthcare sector rose 35% in 2020 and another 53% in 2021, according to Fortified Health Security reports. Bad actors are making sure that healthcare organizations either spend now on security defenses or pay later for ransoms, fines and lawsuits.
You can start the process with a three-point plan focused on prevention, detection, and vigilance. Here are some focused recommendations from this three-point plan:
Inline security solutions are a high impact technique that address security threats, especially ransomware targeting healthcare networks. These solutions can eliminate 90% or more of incoming security threats before they even enter your network. An inline security solution includes both security appliances (like an intrusion prevention system (IPS), web application firewalls (WAF), TLS 1.3 decryption, etc.) and infrastructure components like external bypass switches and network packet brokers to access and deliver complete data visibility. This allows for the examination of ALL suspect data entering the network.
Unfortunately, inline solutions cannot prevent everything. This is why you need a second level of defense that helps you actively search for threats. This part of the plan uses taps and network packet brokers to capture relevant packet data and then feed that data to purpose-built threat hunting tools to proactively look for indicators of compromise (IOC) within network components and Internet of Medical Things (IoMT) devices.
The third level of defense is to periodically validate that your security architecture is working as designed. This means using a BAS solution to safely check your defenses against real-world threats to find any holes before hackers find them for you.
Expect The Unexpected
A focus on cyber resiliency is key to your success. Once a cyber-attack or breach has been launched, you obviously need to stop the threat. However, it is just as important to get back to normal operations as fast as possible to maintain business continuity and satisfy patient needs. The key to making cyber resiliency work safely is to engineer your security architecture with self-healing capabilities from the start.
Some examples of engineered cyber resilience include:
