CompTIA CySA+ Exam: Mitigating Attacks with Time Clock Configuration

Mitigating Attacks with Time Clock Configuration

Question

A security analyst is reviewing the following requirements for new time clocks that will be installed in a shipping warehouse: -> The clocks must be configured so they do not respond to ARP broadcasts.

-> The server must be configured with static ARP entries for each clock.

Which of the following types of attacks will this configuration mitigate?

The configuration of the time clocks to not respond to ARP broadcasts and the server to be configured with static ARP entries for each clock will help mitigate spoofing attacks.

ARP (Address Resolution Protocol) is a protocol used by network devices to map a known IP address to a corresponding MAC (Media Access Control) address. ARP broadcasts are typically used to discover the MAC address of a particular device on a local network.

Spoofing attacks occur when an attacker sends falsified ARP messages to the network, mapping their own MAC address to a valid IP address on the network. This causes all traffic destined for that IP address to be sent to the attacker's machine instead of the intended recipient. By configuring the time clocks to not respond to ARP broadcasts and the server with static ARP entries, it prevents attackers from discovering the MAC address of the time clocks and using that information to launch spoofing attacks.

This configuration does not address overflow attacks, rootkits, or sniffing. Overflow attacks involve overflowing a buffer or input field to execute malicious code or gain access to privileged information. Rootkits are malicious programs that allow attackers to maintain access and control over a compromised system. Sniffing is the practice of intercepting network traffic to capture sensitive information.
