An organization requires immediate notification of unauthorized alterations to their financial system's executable files to maintain the integrity of its processing environment. Which implementation will best meet this requirement?
Deploy a system that provides real-time alerts for modifications to sensitive files.
Enhance antivirus settings to perform hourly scans of financial data
Configure an intrusion detection system to scan for network breaches.
Schedule regular event log auditing to track user access and changes.
Implementing a system that proactively monitors and reports changes to critical files in real-time aligns with the organization’s need for immediate alerts when important files have been modified. While both an intrusion detection system and an antivirus aim to protect against unauthorized activities, they are not specifically tailored for the continuous monitoring of file integrity. Event log auditing, though valuable, is more reactive and does not typically focus on detecting changes at the file level. Therefore, the selected system satisfies the necessity for rapid identification of any unauthorized file alterations.
