Final answer:
A DOS attack overwhelms a system with traffic, phishing attacks trick individuals into revealing sensitive information, and ransomware attacks encrypt files or systems for a ransom.
Step-by-step explanation:
DOS Attack:
A DOS (Denial of Service) attack is a type of cybersecurity attack that overwhelms a system or network with a flood of traffic, making it unavailable to users.
Example: In healthcare, a DOS attack on a hospital's website can disrupt access to patient records and online services, affecting the hospital's ability to provide timely care.
Phishing Attack:
A phishing attack is a type of cybersecurity attack that tricks individuals into revealing sensitive information by impersonating a trustworthy entity.
Example: A phishing attack targeting healthcare providers may use an email that appears to be from a reputable medical organization, asking for login credentials to gain access to patient data.
Ransomware Attack:
A ransomware attack is a type of cybersecurity attack that encrypts a victim's files or systems and demands a ransom for their release.
Example: A ransomware attack on a healthcare facility's network can lock down critical patient information, leading to disruptions in patient care and potentially jeopardizing patient safety.
