What is a Data Breach?
The term Data Breach refers to a cyberattack that results in confidential, private, protected or sensitive information being exposed to someone who is not authorized to access it. Data breaches can be caused by malicious actors who steal information to commit fraud or other crimes, or they can be the result of an accidental event, such as a physical data loss or unintentional exposure of information through security weaknesses.
Healthcare is a particularly vulnerable industry to hackers, with the recent attack on Michigan’s McLaren Health Care system compromising data from over 743,000 patients. The incident highlights the need to consider cybersecurity risks across your entire organization. The best way to reduce risk is to implement a multi-layered defense. This includes implementing secure cloud solutions, limiting data access to only essential users, and conducting penetration testing to identify vulnerabilities.
Insider leaks: Current employees or trusted partners with privileged access can abuse their rights, resulting in data breach incidents. The motivations for these attacks are often financial gain or revenge.
Other data breaches are the result of hacking or malware, such as ransomware attacks that require payment in order to return a business’s systems back online. These types of attacks exploit vulnerabilities in third-party applications, misconfigurations in software and servers, or the use of weak credentials.
Once a data breach has occurred, it is important to investigate and remediate the situation as quickly as possible. This can be done by deploying forensic tools to capture and analyze affected data, assess damage, and create new insights to prevent future incidents. You should also make sure that your law enforcement contacts are notified about the breach so that they can inform affected individuals and other businesses, as appropriate.
