A UPS (Uninterruptible Power Supply) is a device that provides power backup to a computer or other electronic devices in case of a power outage or other electrical disturbance. It acts as a battery backup that keeps the devices running for a certain amount of time, allowing users to safely save their work and shut down the system properly.
From the given options, the correct answer is C. Power outages. A UPS is specifically designed to protect against power outages, which are interruptions in the electrical power supply. Power outages can be caused by a variety of factors, including weather events, equipment failures, or power grid maintenance. When a power outage occurs, a UPS will switch to its battery backup, allowing connected devices to continue operating without interruption. This can prevent data loss, system damage, and downtime.
Denial of Service (DoS) and Replay Attacks are both cybersecurity threats, and a UPS does not provide protection against these types of attacks. DoS attacks involve flooding a system or network with traffic, overwhelming it and causing it to crash or become unavailable to users. Replay attacks involve intercepting and re-transmitting data between two parties in an attempt to gain unauthorized access to a system.
Wiretapping involves intercepting and recording communication between two parties, typically through physical access to a network or device. While a UPS does not directly protect against wiretapping, it can help protect against data loss that may occur during a power outage, which could make it easier for attackers to gain access to sensitive information.
In summary, a UPS provides protection against power outages, but does not protect against cybersecurity threats such as DoS or Replay Attacks, or against wiretapping.
