The healthcare industry is under a constant threat of cyber attacks, mostly due to the fact that organizations within this sector keep a variety of confidential and pertinent information, such as credit card information, social security numbers, insurance-related information, and some believe most importantly personal medical records.
A recent report states that healthcare entities have been under increased risk of targeted attacks lately, including phishing attacks, ransomware attacks, and network hacking attacks. The heightened risk for cyber attacks points to a growing need for enhanced protection, in addition to raising awareness of the different types of cyber attacks that many healthcare organizations are facing.
Healthcare Surpasses Financial Sector as the Most Frequently Attacked Industry
According to data provided by Advisen and Hiscox, the average cost of a cyber incident in the healthcare industry cost $150,000. A recent report published by IBMstates that the healthcare industry was attacked more frequently than any other sector last year, replacing the financial services sector at the top. According to the report, over 100 million healthcare records were compromised in 2015, which is a staggering figure by all standards.
The Advisen and Hiscox report also notes that there has been a 1.6-times increase in Health Insurance Portability and Accountability Act (HIPAA) violations in the last five years. This statistics suggests that entities such as hospitals and clinics, need to ramp up their efforts for ensuring HIPAA compliance, because it is one of the key steps toward achieving improved protection against cyber attacks.
Detecting Ransomware and Phishing Attacks
Currently , the most common cyber threats faced by healthcare entities include phishing attacks and ransomware. These are the most commonly used techniques by hackers trying to retrieve confidential patient information that is critical to protect . The best practices for preventing such threats involve data encryption tools, which are recommended for all covered entities.
Another solution that can be useful to healthcare organizations is a software that can create rules and can be integrated with different tools that can be adjusted in a way that allows them to automatically detect and report problems. Platforms with such capabilities should be a crucial part of each entity’s cyber defense efforts.
How to React in Case You Are Attacked
Even though there are tools designed to detect and prevent ransomware and phishing attacks, hackers often manage to find a way to go around all sorts of defences and breach even the most sophisticated security armours. When that happens, organizations must be prepared to react as quickly and as effectively as possible with a proven solution.
To that end, all covered entities, including healthcare organizations, need to have a Computer Security Incident Response Team (CSIRT) in place. In order to help their CSIRT resolve cyber incidents, entities are advised to acquire platforms that have the ability to automatically notify CSIRTs when a cyber attack occurs, be it via e-mail or SMS, and gather a team of investigators to do the forensics on a given incident.
Incident response platforms featuring specialized playbooks are also necessary for tackling healthcare-related incidents. They are the most indicated tool for resolving cyber incidents fast and efficiently, through their ability to accelerate the incident triage process, integrate with forensics and response systems, and predict similar events in the future. Some of those platforms (SIRPs) are also able to provide playbooks for vertical regulation, such as HIPAA and similar.
