Final answer:
Both website defacement and DoS are cyber attacks aimed at websites. Website defacement alters the site's appearance, while DoS makes the site unavailable by overwhelming it with traffic.
Step-by-step explanation:
Both website defacement and DoS (Denial of Service) are cyber attacks against websites, therefore the correct answer is C) Both A and B. Website defacement is an attack where the visual appearance of a website is altered by unauthorized users. A Denial of Service attack, on the other hand, aims to make a website or service unavailable to legitimate users by overwhelming the site with excessive traffic or exploiting a weakness.
Hackers use a variety of methods to compromise websites and lure individuals into malicious activities, such as clicking on harmful links or divulging sensitive information. It is essential to implement robust security measures to protect against these types of attacks.
