Zero-Day Attack Prevention:

These exploits are unpredictable, zero-day protection is necessary. Here are some suggestions regarding how to safeguard your software and vulnerable programmes from zero-day attacks.

• Once the security patches are available, update all programmes and software.
• Web application software must be employed to secure the website. You are capable of precisely detecting attacks.
• Install a security package for the internet. It often comprises default-deny protection, heuristic file analysis, smart anti-virus, and sandboxing techniques.
• Operate on sites that are secured with Secure Socket Layer (SSL).
• Go for multiple layer protection with Web application firewalls
• Protect the content of individual transmissions with the help of Virtual LANs.
