What is Proxy log?
A record of the web requests users made through a proxy server, and often the only place outbound traffic is visible.
A proxy log records the web requests that users and systems make through a forward proxy: time, source host, destination URL or domain, response code, bytes transferred and often the user agent.
In many networks the proxy is the only place outbound web traffic is recorded centrally, which makes these logs essential for finding command and control, data exfiltration and visits to phishing pages.
