Cybersecurity in Healthcare Industry: Challenges and Solutions

Cybersecurity in Healthcare Industry Challenges
and Solutions
https//cybernewslive.com/
2
In their pursuit of digital transformation, the
healthcare and public health (HPH) sectors have
consistently welcomed technological advancement.
Even before the COVID-19 epidemic, hospitals and
medical institutions required digital solutions
and collaboration tools to communicate with both
patients and employees. However, these new
technologies have merely increased their attack
surface, which bad actors are taking advantage
of. Healthcare cybersecurity dangers range from
data breaches to ransomware to insider threats.

Furthermore, monitoring legal compliance in the
healthcare industry is quite difficult. Because
of the volume and velocity of data generated by
hospitals and medical institutes around the
world, they sit on data lakes. An unprotected
hospital server is ripe for a malpractice
complaint. Regulation is stringent and
complicated. This is why healthcare providers
must implement a hospital cybersecurity and
compliance solution to safeguard sensitive data.

Cyberattacks and Security Issues in the
Healthcare Sector

• Healthcare cybersecurity should be especially
  concerned about the following threats
• Ransomware
• Criminals not only encrypt data and demand money
  to decrypt it, but they also restrict access to
  the entire medical system, making surgical
  instruments and life support equipment
  ineffective.

5

• Phishing
• Malware can infiltrate computer systems via links
  or attachments in phishing emails, social media
  posts, or text messages, quickly spreading
  throughout the network.
• Network vulnerability attacks
• To gain access to patient data, cybercriminals
  use HTTPS spoofing, ARP cache poisoning, and
  other techniques to attack medical facilities
  wired and wireless networks.

6

• Man-in-the-middle (MITM) attacks
• Cybercriminals spy on private (and vital) user
  information during data transfers or talks,
  resulting in severe losses and penalties for a
  violation of confidentiality.
• Data Breaches
• In comparison, the healthcare industry has an
  unusually large amount of data breaches. Despite
  efforts to prevent these occurrences through
  frameworks such as HIPAA, cybersecurity gaps
  provide cyber attackers with access points
  through which they can continue to operate.

Cyberattacks Against Medical Devices
Healthcare IT specialists find it especially
challenging to maintain security due to the vast
number of networked medical equipment, many of
which have varied specifications and come from
different manufacturers. Even while medical
devices do not necessarily hold a large amount of
patient data, they can provide easy access points
for hackers to servers containing large amounts
of data. To limit the costs and harm caused by
unauthorised access, the healthcare cybersecurity
industry must prioritise maintaining these entry
points safe and up to date.

Cybersecurity Solutions for the Healthcare
Industry

• As a healthcare cybersecurity solution, below are
  many security precautions that may be done as
  cybersecurity for hospitals and healthcare
  institutions to safeguard electronically
  protected health information (ePHI) by defending
  tools, digital systems, networks, and data
  against threats.
• Control of data consumption
• Clinics should contain and monitor malicious file
  activity. They can accomplish this by putting in
  place systems that restrict data access, prevent
  unauthorised emails from being shared, and block
  copies to external sources, among other things.

9

• Record data
• Keep track of information in order to detect
  unauthorised access to patient data as soon as
  possible. Logs will let an organisation detect
  and close a speedy breach in the event of a
  cyberattack.
• Impose stringent access restrictions
• To safeguard patient data from illicit
  activities, they must utilise a password/PIN,
  cards and keys, face, fingerprint, or retina
  recognition.

10

• Apply cutting-edge cryptography
• Use contemporary cryptography to encrypt data
  during transmission and storage. Safe multiparty
  computation, Homorphic encryption, and
  distributed ledger systems are a few examples.

What Makes Cybersecurity in Healthcare so
Challenging?
Any of the cybersecurity problems that any
company faces, as well as specific challenges to
the healthcare business, exist. They must defend
against endpoint, database, and network assaults.
They are in charge of protecting their patients
and employees sensitive financial and medical
data. They are frequently called upon to defend
priceless intellectual property. They also
encounter challenges that few other businesses
do. Over the last ten years, the number of
networked medical devices has skyrocketed. Almost
all medical gadgets are web-enabled or linked to
the operational network of the organisation.
12
Healthcare providers deploy more connected
medical devices on a regular basis, accounting
for up to 74 of all devices connected to a
hospitals network, according to healthcare
cybersecurity statistics. Due to the prevalence
of medical device hijacking, the term mud
jacking is now often used to refer to assaults
primarily targeting linked medical
equipment. Often, the patients life is
dependent on the connected equipment. It can mean
the difference between life and death if you can
disable or alter them. They, like any other
digital device, require updates to remain
functioning and safe.
13
Some examples of connected medical equipment
include crash cart equipment tracking, patient
monitoring bracelets, ventilators, portable X-ray
machines, and vital sign monitors. These devices
communicate throughout the hospital network,
providing clinicians with access to vital patient
data stored in electronic health records. The
transferred data allows doctors to provide more
inexpensive healthcare. Doctors can work faster
and more safely. Each of these gadgets acts as a
gateway for cybercriminals.
