What Is Cybersecurity?

Cybersecurity is the practice of protecting digital systems, devices, networks, applications, and information from unauthorized access, attacks, damage, or disruption.

A strong cybersecurity strategy focuses on three core principles:

• Confidentiality: Keeping information private and accessible only to authorized users.
• Integrity: Protecting information from unauthorized changes.
• Availability: Ensuring systems and data remain accessible when needed.

Cybersecurity combines technology, policies, processes, and human awareness.

1. Create Strong and Unique Passwords

Passwords are still one of the most important defenses for online accounts.

A common mistake is using the same password across multiple services. If one website suffers a breach, attackers may try those credentials on other platforms.

Instead, use a unique password for every important account.

A strong password should generally be:

• Long
• Unique
• Difficult to guess
• Free from obvious personal information

Avoid using names, birthdays, phone numbers, or common phrases.

Use a Password Manager

A reputable password manager can generate and store unique passwords securely.

This allows users to create stronger credentials without needing to memorize dozens of passwords.

2. Enable Multi-Factor Authentication

Multi-factor authentication, or MFA, adds another layer of security.

Depending on the service, MFA may involve:

• Authentication applications
• Security keys
• Verification codes
• Biometrics
• Other approved methods

Even if someone obtains your password, an additional authentication factor can make account takeover more difficult.

Accounts That Need MFA

Prioritize MFA for:
