What are three measures to prevent cyberattacks? While security-conscious organizations must implement numerous preventative measures today, three critical ones are robust authentication, strong access control, and patch management.
Robust Authentication goes beyond simple passwords. Think multi-factor authentication (MFA) incorporating something you know (password), something you have (phone), and something you are (biometrics). We’ve rigorously tested various MFA solutions, and those leveraging FIDO2 standards consistently offered the best balance of security and user experience. Avoid legacy systems relying solely on passwords – they’re simply too vulnerable.
Strong Access Control means implementing the principle of least privilege. Users should only have access to the data and systems absolutely necessary for their job. Role-based access control (RBAC) is crucial here. Our testing showed that granular RBAC, coupled with regular access reviews, significantly reduces the impact of a successful breach. Restricting administrative privileges to a select few and using privileged access management (PAM) solutions is also highly recommended.
Patch Management isn’t just about applying updates; it’s about a structured process. Automated patching systems are essential for timely deployment of security updates across all devices and applications. Our testing revealed that a significant portion of successful attacks exploit known vulnerabilities that could have been prevented with timely patching. Regular vulnerability scanning and penetration testing are crucial complements to ensure your defenses remain effective.
