What characteristic describes spyware?
- a network device that filters access and traffic coming into a network
- software that is installed on a user device and collects information about the user

Explanation: Spyware is a specific type of malicious software (malware) that is installed on an end device—such as a computer or smartphone—often without the user's knowledge. Its primary characteristic is that it secretly collects information about the user, which can include browsing habits, personal data, or sensitive credentials. Unlike other attacks that might aim to crash a system or delete data, spyware focuses on stealthily monitoring activity for the purpose of information theft. It is categorized as a common external security threat that requires host-level protection, such as antispyware applications, to mitigate.
