Cybersecurity best practices for business

As the high frequency of cyberattacks poses significant risks, protecting your networks, data, and devices is critical. Implementing robust cybersecurity practices helps reduce your vulnerability to data breaches and unauthorized access. 

To foster a secure digital environment, the U.S. Cybersecurity & Infrastructure Security Agency recommends: 

  • Deploying firewalls and anti-virus software 
  • Choosing strong passwords and using password management practices and techniques 
  • Updating software to ensure you’re using the most current protection against threats 
  • Thinking before opening suspicious emails and text links 
  • Turning on and using multi-factor authentication

Following these best practices helps mitigate risks and protect against phishing, ransomware, denial-of-service attacks, and other malicious activities.
