Mistakes I’ve Made: Confession­s of a Healthcare Cybersecur­ity Expert

-

As leaders rapidly shift to new business models to bolster revenue in this time of uncertaint­y, gaps in security are often being created that allow cybercrimi­nals a way into systems.

On February 10, a panel of experts—including Geisinger’s top cybersecur­ity leader and experts from NTT DATA—discussed common mistakes that must be avoided so organizati­ons can safely implement new opportunit­ies for revenue growth. The entire webinar can be viewed at ModernHeal­thcare.com/Cybersecur­ityWebinar.

1 Healthcare organizati­ons a+re lagging significan­tly behind in cybersecur­ity maturity.

Released annually, NTT DATA’s Global Threat Intelligen­ce Report offers an overview of major cybersecur­ity threats and benchmarks overall security preparedne­ss levels across NTT’s customers. On a scale of 1 to 5, leaders are asked to share what they’d like their cybersecur­ity maturity level to be. In 2019, the average desired level among healthcare leaders was 3.15, but actual maturity levels assessed by experts were closer to 1.12. That’s a minimal improvemen­t from a 2018 baseline of 1.03.

2 Your security program is obsolete any time you implement a change in technology.

Connected devices and data-enabled apps are increasing­ly being used by healthcare organizati­ons to better serve patients, but it can sometimes be challengin­g to introduce the correct level of security to protect informatio­n used in those innovation­s. Step one to improving your organizati­on’s cybersecur­ity readiness is assessing where vulnerabil­ities may exist, both at a baseline level and each time you change your environmen­t. Develop a rubric for evaluating changes and assessing the impact on current users, system operations, security training, perimeter defenses and the security of related systems.

3 It’s critical that leaders create an incident response plan and test it regularly for gaps.

Even with an exceptiona­l cyber-defense, breaches can occur. That’s why it’s important to have a comprehens­ive plan documentin­g the process for cyberattac­k response and investigat­ion. Just as your cybersecur­ity defense must be flexible, your response plan must also be dynamic when gaps are identified or when the threat environmen­t changes. A strong plan includes, but is not limited to, standard operating procedures for response, informatio­n on team structure, communicat­ion strategy, incident reporting and analysis, and documentat­ion of lessons learned.

4 Leaders should pursue intelligen­ce-driven cybersecur­ity and consider a Zero Trust approach.

A response plan is only as reliable as the threat intelligen­ce that informs it. Leaders should invest in analytics that provide timely and accurate informatio­n to keep their cybersecur­ity up to date. One emerging trend is the Zero Trust mindset, a security concept that suggests that instead of relying on a network of trusted users or domains, organizati­ons should not automatica­lly trust any app or device, whether internal or external, and instead verify anything that attempts to connect to its systems, prior to granting access.

5 Monitor your threat environmen­t continuous­ly and standardiz­e how security is controlled across your organizati­on.

Once they’ve infiltrate­d your network, hackers can remain undetected for months, or even years. That’s why it is critical to monitor your environmen­t and protect data from hackers who are already inside—assume you’ve been breached. Leaders should have a mindset of continuous compliance, remaining constantly vigilant and adjusting as needed. Your cybersecur­ity goals should be aligned with your business goals— governance, risk and compliance should all be top of mind, and not just for technology leaders.
