Which of the following is a recommended cybersecurity practice?

• A. Use strong passwords
• B. Reuse passwords across sites
• C. Click every link in emails
• D. Ignore security updates

Answer: (A)

Using strong passwords is a fundamental cybersecurity habit. A strong password is long, combines uppercase and lowercase letters, numbers, and symbols, and isn’t based on easily guessed information. It should be unique for each site, so a breach on one service doesn’t grant access to others. In practice, using a password manager to generate and store these unique passwords, and enabling multi-factor authentication when available, provides an extra layer of protection. This approach directly reduces the risk of unauthorized access from guessing or credential dumps. Reusing passwords across sites creates a single point of failure: if one site is breached, attackers can try that same password on other accounts. Clicking every link in emails invites phishing and malware. Ignoring security updates leaves software vulnerable to known exploits.
