Firewall: Your Network Security Barrier
Firewalls are essential tools for protecting networks from hackers, malware, and other threats. Available in both hardware and software forms, firewalls offer essential protection between networks and potential external attacks.
Firewall Features
IT managers configure firewalls based on specific system requirements, ensuring data is secure. Once implemented, firewalls are constantly monitored to ensure maximum security.
Firewall Types
- Hardware Firewalls: Primarily used by large companies to restrict access between departments or from outside.
- Software Firewalls: Generally sufficient for small businesses and personal computers, as they offer protection without the need for dedicated hardware.
Integration with Other Security Tools
Firewalls overlap significantly with network security software and web security software, as they all aim to protect systems and information. Some firewall products also include vulnerability management tools to identify and address threats.
Firewall Requirements
A product must meet certain criteria to be classified as a firewall:
- Evaluate and filter user access.
- Create barriers between networks and the Internet.
- Alert administrators to unauthorized access.
- Apply security rules and authentication.
- Automate tasks associated with testing and monitoring.
