What is a Proxy firewall? |
|
Answer» A proxy firewall protects network resources by filtering packets at the application layer, rather than the network or transport layers. However, applications may slow down and functionality may be affected by using one. Traditional firewalls do not focus on decrypting traffic or inspecting application protocol traffic. As a result, only a small portion of the threat landscape is covered by IPSs or antivirus solutions. Proxy servers act as a conduit between two networks, providing an intermediary between computers and servers on the internet so that secure data may be passed back and forth. A proxy server blocks, filters, archives, and manages requests from devices in order to protect networks from cyberterrorism and unauthorised access. It decides which traffic is permitted and denied and detects signs of a cyberthreat or malware intrusion. |
