Simple Network Management Protocol. Network management protocol used almost exclusively in
SNMP
TCP/IP networks. SNMP provides a means to monitor and control network devices, and to manage
configurations, statistics collection, performance, and security.
SNMP Version 2. Version 2 of the network management protocol. SNMP2 supports centralized and
SNMP2
distributed network management strategies, and includes improvements in the SMI, protocol
operations, management architecture, and security.
Address of a network device that is sending data.
source address
Statistics Processor. Keeps track of system statistics such as packet counts and packet arrival rates.
SP
Switched Port Analyzer. Feature of the Catalyst 5000 switch that extends the monitoring abilities of
SPAN
existing network analyzers into a switched Ethernet environment. SPAN mirrors the traffic at one
switched segment onto a predefined SPAN port. A network analyzer attached to the SPAN port can
monitor traffic from any other Catalyst switched port.
Loop-free subset of a network topology.
spanning tree
Structured Query Language. International standard language for defining and accessing relational
SQL
databases.
Type of RAM that retains its contents for as long as power is supplied. SRAM does not require constant
SRAM.
refreshing, like DRAM
Stream Reassembly Processor. Reorders TCP streams to ensure the arrival order of the packets at the
SRP
various stream-based inspectors. It is also responsible for normalization of the TCP stream. The
normalizer engine lets you enable or disable alert and deny actions.
Secure Shell. A utility that uses strong authentication and secure communications to log in to another
SSH
computer over a network.
Secure Socket Layer. Encryption technology for the Internet used to provide secure transactions, such
SSL
as the transmission of credit card numbers for e-commerce.
A DDoS tool that relies on the ICMP protocol.
Stacheldraht
Stateful searches of HTTP strings.
STATE engine
See SP.
Statistics Processor
See SRP.
Stream Reassembly
Processor
A signature engine that provides regular expression-based pattern inspection and alert functionality for
STRING engine
multiple transport protocols, including TCP, UDP, and ICMP.
A more granular representation of a general signature. It typically further defines a broad scope
subsignature
signature.
Refers to attaching rubber feet to the bottom of a sensor when it is installed on a flat surface. The rubber
surface mounting
feet allow proper airflow around the sensor and they also absorb vibration so that the hard-disk drive is
less impacted.
