In cybersecurity, a "Data Breach" refers to the unauthorized access and retrieval of sensitive data by malicious actors. This breach can involve various types of information, such as personal identification, financial records, or intellectual property. Data breaches can have serious consequences for individuals and organizations, including financial loss, reputational damage, and legal repercussions. Organizations often invest in security measures to prevent data breaches, as the fallout can lead to significant loss of trust from customers and stakeholders.
