Cyber Security Update

Cyber Security Key Statistics

Icon
  • There have been a lot of high-profile data breaches1
  • Hacking continues to be the biggest breach event category, even though it is only 11% of the "Number of Incidents"
  • 96.7% of all patient data hacked took place in 2015!
  • Even a great security program has vulnerabilities that can eventually be exploited (100% secure = 0% functional)
  • "Hackers took an average of 100 hours to get into a good IT infrastructure and 147 hours to breach an excellent infrastructure; however, after an average of 209 hours trying to get in, they gave up" (Scott Whyte, senior vice president at ClearDATA)
  • Cyber-attackers only have to succeed once
 
Year Hacking Events Reported to HHS Number of Hacking Events Reported Number of Patients Affected in Hacking Events for the Year
2010 10 568,358
2011 16 297,269
2012 16 900,684
2013 19 206,998

Primary Cyber Threat Agents
 
  • Organized crime (e.g., Russian mafia)
  • Nation states (e.g., North Korea, China, Iran)
  • Hacktivists (e.g., Anonymous and Lizard Squad)
  • Business Associates (Responsible for 17% of the reported breaches to HHS)
  • Malicious and negligent insiders (e.g., an authorized user misusing their access privileges)
 
Targets of Cyber Criminals
 
  • User credentials (user IDs and passwords)
  • Protected Health Information (PHI)
  • Credit card data and bank account numbers
  • Social Security Numbers
  • Research data and proprietary data
  • Smartphones
  • Biomedical devices (affects patient health and safety)
 
Internet of Things
 
  • The "Internet of Things" makes some tasks easier but increases risks for hacking
  • Remote control and monitoring are widely used in healthcare
   

Every hospital employee and workforce member is a prime target for an attack!

 
Challenges
 
  • Cyber-attacks and hacking grew more sophisticated; attackers are evolving
  • Even the strongest security won't prevent all breaches; not prepared for an evolving adversary
  • Breaches are taking longer to detect and resolve (204 days is the average time a hacker/intruder is inside a company's network before detection)
  • High demand for cybersecurity professionals; currently is a negative unemployment rate
  • Cost associated with attacks are going up
    • Identity theft protection
    • Indirect costs too - Reputational harm (hard to measure)
  • Cyber insurance
    • Policy premiums are on the rise because of the rise in cyber attacks
    • Number of exclusions are also increasing, making it more difficult to settle a claim
    • Policy doesn't protect the hospital from breach liability
