If you are thinking that those represent HTTP and HTTPS, you would be largely correct, but that doesn’t mean it’s traffic involving web servers. It’s pretty much impossible to block HTTP and HTTPS ports at the firewall. At most companies, there are multiple DNS servers to collect from and hundreds of routers.

A TCP port is a unique number assigned to specific services and applications that run on a server. It serves as an endpoint for communication between a client and the server, allowing different communication processes over a network. This combination directs network traffic to the appropriate service or application running on a server.

VPNs encapsulate data and encrypt the data using an algorithm contained within the transmission protocol. VPN traffic is encrypted and decrypted at the transmission and receiving ends of the connection. VPNs can also be set up using L2TP/IPsec protocols, which proves to have much stronger encryption than PPTP.
