Message Digest 5. A one-way hashing algorithm that produces a 128-bit hash. Both MD5 and Secure
MD5
Hash Algorithm (SHA) are variations on MD4 and strengthen the security of the MD4 hashing
algorithm. Cisco uses hashes for authentication within the IPSec framework. Also used for message
authentication in SNMP v.2. MD5 verifies the integrity of the communication, authenticates the origin,
and checks for timeliness.
Mega Event Generator. Signature based on the META engine. The META engine takes alerts as input
MEG
rather than packets.
Defines events that occur in a related manner within a sliding time interval. This engine processes
META engine
events rather than packets.
Management Information Base. Database of network management information that is used and
MIB
maintained by a network management protocol, such as SNMP or CMIP. The value of a MIB object can
be changed or retrieved using SNMP or CMIP commands, usually through a GUI network management
system. MIB objects are organized in a tree structure that includes public (standard) and private
(proprietary) branches.
Multipurpose Internet Mail Extension. Standard for transmitting nontext data (or data that cannot be
MIME
represented in plain ASCII code) in Internet mail, such as binary, foreign language text (such as
Russian or Chinese), audio, or video data. MIME is defined in RFC 2045.
A minor version that contains minor enhancements to the product line. Minor updates are incremental
minor update
to the major version, and are also base versions for service packs.
A removable card in a switch, router, or security appliance chassis. AIP SSM, IDSM-2, and NM-CIDS
