Cyber attacks across the healthcare sector are rampant and show no signs of abating. Security and network teams within this industry have the odds stacked against them; proving that it’s crucial to build a multi-faceted security strategy that is smart, both in regards to spend and resources.
When it comes to cyber attacks healthcare is the highest targeted sector. In 2017 there were over 300 breaches. That is over 29 times the number of breaches reported across the hospitality industry.
There are many reasons why healthcare is such an attractive target to cybercriminals, including:
The consequences of a cyber attack
When a provider within healthcare is subject to an IT security breach the ramifications go far beyond the initial internal IT ‘mop-up’:
The potential risk to life – on multiple levels there is a risk to human life, from operations having to be canceled to no access to medical records for emergency treatment, not forgetting the number of IoMT devices which can be compromised. Take a glance at the numerous articles on the web concerning a pacemaker’s vulnerability to hacking, and you’ll soon understand the risk IoMT devices can present.
Brand & reputation – once a data breach becomes public the media feeding frenzy commences. One only has to look to the National Health Service in the UK in 2017 which was effectively brought to a standstill by the WannaCry ransomware. The media coverage was global and prolonged.
In countries where an individual can choose their healthcare provider it’s hardly likely they will trust an organization with their life if that organization can’t be trusted with their personal data.
Financial – loss of productivity, cost of remediation, missing pay for performance deadlines and heavy financial fines from governing bodies and authorities such as HIPAA, not to mention penalties under GDPR, all contribute to weighty post-breach costs.
The costs of Healthcare data breaches far exceed other industries. Following a security breach, The University of Washington Medicine incurred a $750,000 HIPAA fine. In Ponemon’s 2017 Data Breach report it was estimated that a data breach in the Healthcare industry costs an organization $380 per record, in comparison to a global average of $141! For the NHS in the UK, the cost of the fall-out from WannaCry has nearly reached £100m.
Taking all the above into consideration, it is clear that security teams within the Healthcare sector have to be smart with their IT security spending. With reduced resources and funds it’s almost impossible to keep abreast of the latest security threats.
Ransomware attacks declined by 32% in Q1 2018 from Q4 2017, while coin mining (cryptojacking/cryptomining) increased by 1,189%. With such a quickly shifting threat landscape maintaining expertise across all areas is challenging for even large teams, let alone smaller ones.
Healthcare security teams have to look to solutions that automatically mitigate risk, protecting patient data and devices while freeing up precious manpower resources to focus on other issues, without a hefty price tag.
Applied at the DNS level of your infrastructure, these threat feeds automatically stop users from accessing malicious sites including phishing and malware dropper websites.
These threat feeds can be integrated with existing recursive DNS servers, or for those who don’t manage their own DNS, we have a managed service available.
Spamhaus’ Data Query Service (DQS) is an affordable and effective solution to protect your email infrastructure and users.
Using your existing email protection solution, you will be able to block spam and other related threats including malware, ransomware, and phishing emails.
The service has never failed and utilizes the longest established DNSBLs in the industry.
Border Gateway Protocol (BGP) Feeds provide your users and network with up to date protection against botnets and other external attacks.
Set up takes minutes; our data is constantly updated in real time by our experienced researchers on your behalf, and can be utilized in your existing BGP capable routers.
Our Passive DNS allows you to quickly and easily navigate through billions of DNS records to shine a spotlight on potentially malicious internet resources associated with your network or domain.
