CompTIA Security Plus Mock Test Q616

Joe analyzed the following log and determined the security team should implement which of the following as a mitigation method against further attempts?
[00: 00: 01]Successful Login: 015 : local
[00: 00: 03]Unsuccessful Login: 022 : RDP
[00: 00: 04]UnSuccessful Login: 010 : RDP
[00: 00: 07]UnSuccessful Login: 007 : RDP
[00: 00: 08]UnSuccessful Login: 003 : RDP

A. Reporting
C. Monitor system logs
D. Hardening

Correct Answer: D
Section: Threats and Vulnerabilities

We can see a number of unsuccessful login attempts using a Remote Desktop Connection (using the RDP protocol) from a computer with the IP address
Someone successfully logged in locally. This is probably an authorized login (for example, Joe logging in).
Hardening is the process of securing a system. We can harden (secure) the system by either disallowing remote desktop connections altogether or by restricting which IPs are allowed to initiate remote desktop connections.

Incorrect Answers:
A: Reporting is not used to prevent unauthorized login attempts.
B: An intrusion detection system (IDS) is a device or software application that monitors network or system activities for malicious activities or policy violations and produces reports to a management station. An IDS could detect the attempted logins but it would not prevent them. “Hardening” is a basic security principle which should be applied to every system.
C: Monitoring system logs will keep you informed about any potential problems with the computer system. However, it will not prevent unauthorized login attempts.
