Dealing with Cybersecurity Challenges in Healthcare Industry

Take One Look at January to March Cyberthreat Trends
-
40% of malicious URLs were found on good domains. It is usual for legitimate websites to be hacked.
-
36% of phishing attacks get increased. Phishing sites now use HTTPS or SSL certificates to help internet users believe that website pages are legal and secure.
-
The percentage of ransomware attacks also gets increased by 148% in March 2020 compared to Feb 2020.
Criminals constantly try to attack on the health care industry for various reasons. Everyone knows clinics and hospitals have a low level of automation for information security and support. Many of them are dependent on outdated software. Additional threats are linked to digital transformation, trust deficit, remote data access, and the reason for online risks in healthcare is the lack of training. It is suspected that COVID-19 can have a far-reaching impact on this industry.

Ransomware Attacks
Ransomware takes control over the files in the infected system and allows attackers to demand a large sum of money. Since 2016, there have been around 172 ransomware attacks on healthcare organizations in the U.S. The biggest problem is these attacks cost more than US$157 million to health care departments. The health care sector is already beating with the NetWalker Ransomware Gang, which is specializing in spreading attacks through spam emails. One of the haunting attacks in health care happened in 2017. At this time, WannaCry ransomware punctured the U.K.’s National Health Service (NHS) hospitals. About 19,000 appointments were cancelled, so you can expect the massive disruption in the medical field during this attack. Nearly one-third of NHS trusts were affected and suffered a loss of US$155 million.
Insider Threats
Telemedicine and Remote Connectivity
Nowadays, clinics and hospitals run at limited capacity due to the fastest spread of Coronavirus infections. They allow only those patients first who can’t be treated well at home. Patients with fewer symptoms are suggested to get treatments through online consultations. Telemedicine has been popular for many years. Before the pandemic outbreak, patients were less active for virtual visits to doctors. However, people prefer safety today, and they are ready to contact doctors online. Thousands of clinics in the United Kingdom choose remote consultations. Due to a cluttered bureaucracy and regulatory restrictions, companies had limited access to telemedicine. In Europe, standards for data protection and privacy are very strict. Right now, healthcare organizations have no option left except to choose telehealth and their operations. The more technologies companies will adopt, the more cyber-attacks can happen in the future.

It’s Time to Take Actions Against Cybersecurity in Healthcare Industry
People can easy to trust health care providers with their data because they are proficient in saving lives. To maintain this trust, it is essential for health care organizations to protect and secure their information, especially if they are working through modern applications or software. Health care and life sciences businesses need to develop a robust and highly adaptive security system. IT hygiene requirements should be flexible and implemented and maintained well across all IT and medical devices.
Remember always, there is no particular spot for vulnerabilities in the IT stack. Vulnerabilities can be appeared in the database, the network, servers, or any endpoint of the IT stack. IT professionals should ensure that all systems are patched with the current security patches and develop a process for security updates.
Companies should execute IoT security practices for remotely connected devices and replace outdated systems within the organization. High-risk and internet-facing systems should be hardened based on industry best practices.
One should implement 100% multifactor authentication to protect against unauthorized access. Always use secure web gateways for remote access. You can disable insecure protocols and services if they are not needed and try to prevent data leakage from endpoint controls. Execute automated systems for data encryption, data classification, and data masking.
Companies should also use Data Loss Prevention Systems for networks, emails, and endpoints for real-time loss monitoring. Use data masking solutions with industry best encryption practices. You can conduct access reviews periodically to make sure access is available for authorized users only. It is vital to establish secure coding guidelines and embrace dev-sec-ops and email security for all development programs. You need to focus on managing risks, threats, and vulnerabilities, rather than just focusing on regulatory compliance. Use mandatory quizzes and certifications in planned security awareness campaigns about social engineering attacks.
Use automation and AI for reducing false positives and proactive threat hunting. Companies should plan for quick IT recovery and fast detection to enhance resiliency in case of a breach.
