❓ Frequently Asked Questions
What is cybersecurity and why is it important?
Cybersecurity protects computers, networks, and data from threats, helping maintain privacy, data integrity, and availability.
What makes a password strong, and how should I manage passwords?
A strong password is long (12+ chars), uses a mix of upper/lowercase, numbers, and symbols, and is unique for each account. Use a password manager to keep track of them.
