  2. Don’t be fooled by social engineering

    Social engineering is the art of manipulating people to performing actions or divulging confidential information. Before you let anybody in on sensitive details about you, make sure that you can verify their credibility.

  3. Be extra careful while clicking links and attachments in emails

    Phishing is a method used by Internet scammers who imitate real companies or individuals in email messages to entice people to share user names, passwords, account information or credit card numbers. Be wary before clicking on attachments and links because, even though the sending party might look legitimate, there is a possibility that they might not be.

  4. Strong passwords for accounts and devices

    When creating a password, use a combination of uppercase and lowercase letters, numbers and symbols. The longer your passwords are, the harder they are to crack. Never use the same password for multiple accounts, especially for sensitive sites like social media, email or banking websites. Learn more.

  5. Using multi-factor authentication

    Multi-factor authentication (MFA) is a best practice to help further protect yourself against hacks and social engineering. MFA works by requiring you to login with more than one set of credentials to authenticate your identity. Turn on MFA when a website or app offers it, especially for sensitive sites like social media, email or banking websites.
