Secure
Socket Layer (SSL) and Transport Layer Security (TLS) are cryptographic protocols
widely
adopted and deployed in network communication today. The traffic over SSL/TLS is encrypted
and
signed to ensure security, hence HTTPS. Because encrypted HTTP connections can carry
the same
risks as unencrypted HTTP connections,
Deep Edge scans all
traffic for potential risks and threats.
Deep Edge can enable or disable HTTPS
inspections and exclude specific websites, URL categories, or IP addresses from
inspection. After the traffic is identified, Deep Edge determines the appropriate actions for traffic based on specified policy settings.
to
scan HTTPS traffic, Deep Edge identifies the SSL
connection at the first packet of the SSL handshake, acquires the client IP address
information from the session, if available, and then gets the server host name from
the
handshake record. The connection will not be decrypted if this information matches
any
allowed URL categories, websites, or IP addresses in the Deep Edge exception list.
Information about HTTPS Inspection is shown in corresponding logs and
reports. HTTPS Inspection notifications are also available to inform end-users why
their
actions on the web are being blocked.
