Potential theft of personal information should be of greatest concern for an organization that has detected unauthorized logins to its client database servers, as it poses a serious threat to the confidentiality, integrity, and availability of the client data and the reputation and trust of the organization. Potential theft of personal information is a scenario that involves the unauthorized access, disclosure, or use of the client data by malicious actors, such as hackers, competitors, or insiders. Potential theft of personal information can have significant impacts and consequences for the organization and its clients, such as:
It can compromise the privacy and security of the client data, and expose the clients to identity theft, fraud, or blackmail.
It can violate the legal and regulatory obligations and requirements of the organization, such as the General Data Protection Regulation (GDPR), the Health Insurance Portability and Accountability Act (HIPAA), or the Payment Card Industry Data Security Standard (PCI DSS), and result in fines, penalties, or lawsuits.
It can damage the reputation and credibility of the organization, and erode the confidence and loyalty of the clients, and lead to loss of business or market share.
The other options are not the greatest concerns for an organization that has detected unauthorized logins to its client database servers. Potential increase in regulatory scrutiny is a possible consequence of the unauthorized logins, as it may trigger audits, investigations, or sanctions by the relevant authorities, but it is not the most critical or immediate concern. Potential system downtime is a possible consequence of the unauthorized logins, as it may disrupt or degrade the performance or availability of the database servers or the applications that depend on them, but it is not the most severe or lasting concern. Potential legal risk is a possible consequence of the unauthorized logins, as it may expose the organization to litigation or liability claims by the affected clients or parties, but it is not the most direct or urgent concern.
