A Denial of Service (DoS) attack on a syslog server exploits weakness in which of the following protocols?

The correct answer is B. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). A DoS attack on a syslog server exploits weakness in TCP and UDP protocols. A syslog server is a server that collects and stores log messages from various devices on a network, such as routers, switches, firewalls, or servers.

Explanation

A DoS attack on a syslog server exploits weakness in TCP and UDP protocols. A syslog server is a server that collects and stores log messages from various devices on a network, such as routers, switches, firewalls, or servers. A syslog server uses either TCP or UDP protocols to receive log messages from the devices. A DoS attack on a syslog server can exploit the weakness of these protocols by sending a large volume of fake or malformed log messages to the syslog server, causing it to crash or become unresponsive. The other protocols are not relevant to a syslog server or a DoS attack.
