Data sovereignty refers to the principle that data stored in another country remains subject to the originating country's laws. This is a common concern in cloud computing.

To ensure that sensitive data, such as Personally Identifiable Information (PII), is not modified, the bank should implement file integrity monitoring (FIM). FIM tracks changes to files and provides alerts if unauthorized modifications are detected, ensuring data integrity.
* Full disk encryption protects data at rest but does not prevent or monitor modifications.
* Network access control (NAC) manages access to the network but doesn't monitor file changes.
* User behavior analytics (UBA) detects suspicious user activities but is not focused on file integrity.

Brute force is a type of attack that tries to guess the password or other credentials of a user account by using a large number of possible combinations. An attacker can use automated tools or scripts to perform a brute force attack and gain unauthorized access to the account. The domain activity logs show that the user ismith has failed to log in 10 times in a row within a short period of time, which is a strong indicator of a brute force attack. The logs also show that the source IP address of the failed logins is different from the usual IP address of ismith, which suggests that the attacker is using a different device or location to launch the attack. The security analyst should take immediate action to block the attacker's IP address, reset ismith's password, and notify ismith of the incident.

A honeytoken is a form of deception technology in which a fake asset (such as credentials, files, or database records) is planted in a system or network to detect unauthorized access or malicious activity. The fake password stored in a hidden spreadsheet, with monitoring for access, is a classic example of a honeytoken. It is not an interactive system (like a honeypot or honeynet) but rather a marker or tripwire intended to alert the security team to suspicious behavior. This method helps identify attackers and their methods early in the intrusion process.
