Question

a. Compliance-based IDS
b. Cloud-based IDS
c. Host-based IDS
d. Network-based IDS

Answer 1

Receiving an alert for a file named MyFile.txt.exe on a Windows system likely points to a Host-based Intrusion Detection System (HIDS) detecting a potentially malicious file.

Step-by-step explanation:

If you are on a Windows system and receive an alert that a file named MyFile.txt.exe has been found, this could indicate a warning from a Host-based Intrusion Detection System (HIDS). Such systems are designed to monitor individual hosts or devices on a network for suspicious activity by analyzing system calls, application logs, file-system modifications (such as the creation of executable files), and other host activities. An alert for a file with a double extension, especially one that includes .exe, is often a sign of a potentially malicious file pretending to be a benign text file, which is a common tactic used by malware.
