DPI helps to block these threats before they can infiltrate your system, enhancing your overall security.
Intrusion Detection is another crucial feature that monitors network activity for any unauthorized or suspicious behavior. Avast Firewall uses a comprehensive database of known attack patterns and signatures to identify potential intrusions. In the event of any suspicious activity, the firewall can promptly block or alert you, allowing you to take necessary actions to safeguard your system.
By enabling these advanced features, you are providing your system with robust protection against sophisticated threats and attacks. However, it is important to note that these features may require more system resources and can impact overall network performance. Therefore, it is advisable to carefully assess your system’s capabilities and requirements before enabling Deep Packet Inspection and Intrusion Detection in Avast Firewall.
