spam scoring
The process of grading messages when filtering email for spam. Symantec Mail
Security assigns a spam score to each message that expresses the likelihood that
the message is actually spam. See also suspected spam.
SSH (Secure Shell)
A program that allows a user to log on to another computer securely over a network
by using encryption. SSH prevents third parties from intercepting or otherwise
gaining access to information sent over the network.
SSL (Secure Sockets
Layer)
A protocol that allows mutual authentication between a client and server and the
establishment of an authenticated and encrypted connection, thus ensuring the
secure transmission of information over the Internet. See also TLS.
SPF (Sender Policy
Framework)
A set of standard practices for authenticating email. If the sender's domain owner
participates in SPF, the recipient MTA can check for forged return addresses.
Symantec Mail Security allows you to specify an action for messages that fail SPF
authentication.
spyware
Stand-alone programs that can secretly monitor system activity and detect
passwords and other confidential information and relay the information back to
another computer.
subnet mask
Used to subdivide an assigned network address into additional subnetworks by
using some of the unassigned bits to designate local network addresses. Subnet
masking facilitates routing by identifying the network of the local host. The subnet
mask is a required configuration parameter for an IP host.
A local bit mask (set of flags) that specifies which bits of the IP address specify a
particular IP network or a host within a subnetwork. Used to “mask” a portion of
an IP address so that TCP/IP can determine whether any given IP address is on a
local or remote network. Each computer configured with TCP/IP must have a
subnet mask defined.
Suspected Spammers
A list of IP addresses from which virtually all of the outgoing email is spam,
identified by Symantec based on data from the Probe Network. Part of the Sender
Reputation Service, Suspected Spammers is a sender group within Symantec Mail
Security. You can specify actions to take on messages from each sender group.
Suspect Virus
Quarantine
In Symantec Mail Security, a database that temporarily holds messages suspected
of containing viruses. Messages with suspicious attachments can be held in Suspect
Virus Quarantine for a number of hours, then filtered again, with updated filters,
if available. This processing delay capability enables Symantec Mail Security to
more effectively deal with new virus threats as they emerge.
suspicious attachment
A message attachment that Symantec Mail Security has determined may contain
a virus. You can choose what action to take when a suspicious attachment is
detected.
Symantec Outlook Spam
Plug-in
An application that makes it easy for Outlook users to submit missed spam and
false positives to Symantec. Depending on how you configure the plug-in, user
