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 hostname 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.
