What is the goal of endpoint (address) spoofing?

To increase the speed of network communication

To identify all devices on the network

To encrypt all data transmitted between devices

To impersonate a trusted device and bypass security controls

What is the primary outcome of a buffer overflow attack against a network service?

The service is moved to a different port to avoid detection

The service executes arbitrary code or crashes

The service encrypts all traffic to prevent further attacks

The service automatically patches itself to fix the vulnerability

What is a common security weakness of UPnP that makes it attractive to attackers?

It is a proprietary protocol that is difficult to understand

It requires no authentication for port mapping requests

It only works on wired connections, limiting its attack surface

It uses strong encryption by default

How can Universal Plug and Play (UPnP) be abused by attackers to compromise a network?

It disables all firewall rules to allow unrestricted communication

It changes the default passwords on network devices

It can be used to open ports on firewalls automatically, exposing internal services to the internet

It encrypts all internal traffic, making it harder for defenders to monitor
