NGFW
A
Next-Generation Firewall (NGFW) is an advanced type of firewall that provides
enhanced security features compared to traditional firewalls. Here’s a detailed
look at what makes NGFWs unique:
- Deep Packet Inspection (DPI): Unlike traditional firewalls that only inspect packet headers, NGFWs analyze the entire packet, including the data payload, to detect and block sophisticated threats.
- Application Awareness and Control: NGFWs can identify and control applications regardless of the port or protocol used. This helps manage and secure application usage within the network.
- Intrusion Prevention System (IPS): NGFWs integrate IPS capabilities to detect and prevent attacks by analyzing network traffic for suspicious patterns and behaviors.
- Threat Intelligence: These firewalls use threat intelligence feeds to stay updated on the latest threats and vulnerabilities, allowing them to block known malicious IP addresses, URLs, and domains.
- User Identity Awareness: NGFWs can associate network traffic with specific users, providing more granular control and visibility over who is accessing what resources.
- Advanced Malware Protection: They often include features to detect and block malware, including zero-day threats, through sandboxing and other advanced techniques.
Overall,
NGFWs offer a comprehensive security solution by combining traditional firewall
capabilities with advanced features to protect against modern cyber threats.
