Summary:
- Firewalls and next-generation firewalls are both types of network security devices that protect computer systems from unauthorized access and cyber threats.
- Firewalls are traditional security devices that monitor and control incoming and outgoing network traffic based on a set of predefined rules, while next-generation firewalls (NGFWs) offer more advanced features like application-level control, intrusion prevention, and user or application-based policies.
- NGFWs provide more comprehensive security by combining the functionality of traditional firewalls with additional capabilities like deep packet inspection, user or application identification, and the ability to detect and prevent advanced threats like malware and intrusions.
