What are the vulnerabilities in cyber security?

When dealing with cyberbullying, the first thing is to protect yourself by setting boundaries online: block or mute the accounts of people who are targeting you, and adjust privacy settings to limit who can see your posts or contact you. It’s also essential to keep records of any messages, comments, or posts that are harmful; screenshots and timestamps can be helpful if you need to report the behavior to a platform or even to authorities. Don't engage with the bully or retaliate—responding often escalates situations and can make it harder to resolve. Instead, talk to someone you trust about what's happening, whether it's a friend, family member, or counselor. Finally, take time for self-care offline: engage in activities you enjoy, connect with people who support you, and remind yourself that cyberbullying is a reflection of the bully, not you.
