Zero-day vulnerabilities are security issues within applications, operating systems, software, or hardware that are unpatched or unknown to the creator. This type of vulnerability is ideal for threat actors to exploit and launch a zero-day attack as developers have had no time—or “zero days”—to address and resolve the vulnerability. How to Prevent Zero-Day Vulnerabilities? As zero-day vulnerabilities are unknown to the victim, they are difficult to prevent. However, organizations can protect their businesses, infrastructure, and customers by implementing several best practices. Some best practices for zero-day attack prevention include: Continuously monitor and assess suspicious activity and anomalies for vulnerabilities. Implement least-privilege user access and role-based controls to limit access. Maintain regular system updates and patches to keep systems secure. Leverage firewalls, penetration tests, vulnerability scans, and other security tools. Mandate single-sign on (SSO) and/or multi-factor authentication (MFA) for workspaces. Create an incident management and response plan on how to address issues quickly. Train employees on current threats and how to respond while also notifying the security team.
