Click on the arrows to vote for the correct answer
A. B. C. D. E.B.
Phishing emails with malicious links can cause significant damage to an organization's security posture. To prevent such attacks, organizations can take several measures, as described in the answers provided.
A. Turning on full behavioral analysis to avert an infection: Behavioral analysis is a technique used to monitor the behavior of software to detect and prevent malware infections. However, it may not be the best option to prevent phishing attacks since phishing emails are socially engineered attacks that target human behavior, not software. Therefore, this option is not the best solution to prevent phishing attacks.
B. Implement an EDR mail module that will rewrite and analyze email links: An EDR mail module that rewrites and analyzes email links can help prevent users from clicking on malicious links. It is an effective way to protect the organization against phishing attacks. This solution allows for real-time analysis of links and alerts the user if they are malicious.
C. Reconfigure the EDR solution to perform real-time scanning of all files: This solution does not address the problem of phishing emails that contain malicious links. It is focused on scanning all files, which may not be necessary to prevent phishing attacks.
D. Ensure EDR signatures are updated every day to avert infection: EDR signatures are a way of identifying malware by comparing it to known patterns of malicious code. While updating EDR signatures every day is a good practice, it may not be effective in preventing phishing attacks that use social engineering tactics to trick users into clicking on links.
E. Modify the EDR solution to use heuristic analysis techniques for malware: Heuristic analysis is a technique used to detect new and unknown malware based on their behavior patterns. While it is an effective method for identifying unknown malware, it may not be effective in preventing phishing attacks since phishing emails are socially engineered attacks that target human behavior.
In conclusion, the best solution to prevent phishing attacks with malicious links is to implement an EDR mail module that will rewrite and analyze email links. This solution allows for real-time analysis of links and alerts the user if they are malicious, thereby preventing the user from clicking on the malicious link.
