Key activities include:

  • Reviewing permissions regularly

  • Removing inactive accounts

  • Monitoring authentication activity

  • Enforcing strong authentication controls

  • Limiting administrative privileges

Strong identity hygiene reduces opportunities for attackers to abuse compromised credentials.

 

Best Practice 5: Be Vigilant Against Phishing Attacks

Phishing remains one of the most successful cyberattack techniques.

Attackers use deceptive emails, messages, and websites to trick users into revealing sensitive information.

Best practices include:

  • Verifying sender identities

  • Avoiding suspicious links

  • Reviewing email addresses carefully

  • Confirming unexpected requests

  • Reporting suspicious communications

Awareness and caution significantly reduce phishing risks.

 

Best Practice 6: Secure Personal and Business Devices

Every connected device represents a potential entry point for attackers.

Device security should include:

  • Screen locks

  • Device encryption

Lost, stolen, or compromised devices can expose sensitive information if not properly secured.

 

Best Practice 7: Protect Sensitive Data

Data is one of the most valuable assets in any organization.

Data hygiene practices include:

  • Classifying sensitive information

  • Restricting access

  • Encrypting data

  • Using secure storage solutions

  • Disposing of data securely

Proper data protection helps prevent unauthorized disclosure and regulatory violations.

 

Best Practice 8: Follow the Principle of Least Privilege

Users should receive only the access necessary to perform their responsibilities.

Excessive permissions create unnecessary risk.

Organizations should:

  • Limit administrative privileges

  • Conduct access reviews
