How well do you know Proxy Servers and Proxy Firewalls?

Understanding Proxy Servers and Proxy Firewalls

• A proxy server acts as an intermediary between a user's device and the internet, allowing caching, security, administrative control, and anonymous surfing.
• Proxy servers can be used for legal and illegal purposes, and users can access them online or configure web browsers to use them constantly.
• Proxy servers may serve many users or just one per server, and there are different types of proxy servers, including shared and dedicated proxies.
• A proxy firewall is the most secure form of firewall, which filters messages at the application layer to protect network resources.
• A proxy firewall limits the applications that a network can support, which increases security levels but can affect functionality and speed.
• Traditional firewalls are not designed to decrypt traffic or inspect application protocol traffic, but a proxy server firewall addresses this gap by providing a gateway or intermediary between computers and servers on the internet to secure data that goes in and out of a network.
• A proxy server firewall caches, filters, logs, and controls requests from devices to keep networks secure and prevent access to unauthorized parties and cyberattacks.
• A proxy firewall is considered the most secure form of firewall because it prevents networks from directly contacting other systems.
• A proxy firewall works by providing a single point that enables organizations to assess the threat level of application protocols and implement attack detection, error detection, and validity checks.
• A proxy network will likely have one computer directly connected to the internet, and other computers in the network access the internet by using the main computer as a gateway, which enables the proxy to cache documents requested by multiple users.
• A user attempting to access an external site through a proxy firewall would do so through a process that involves SYN and ACK packets sent between the user's device, the proxy server, and the external server.
• Requests made through the client-to-proxy connection and the proxy-to-server connection will be analyzed to ensure they are correct and comply with the corporate policy until either side terminates the connection.
