Section 23 Monitoring and Auditing Flashcards
Network traffic is analyzed for predetermined attack patterns.
Signature Based
A baseline is established and any network traffic that is outside of the baseline is evaluated.
Anomaly Based
Activity is evaluated based on the pervious behavior of applications, executables, and the operating system in comparison to the current activity of the system.
Behavior Based
Process of measuring changes in networking, hardware, software, and appliances.
Baselining
Documenting and reporting on the changes in a baseline.
Baseline Reporting
Risk level to which a system or other technology element is exposed.
Security Posture
Network adapter is able to capture all of the packets on the network regardless of the destination MAC address of the frames carrying them.
Promiscuous Mode
Network adapter can only capture the packets addressed to itself directly.
Non-Promiscuous Mode
One or more switch ports are configured to forward all of their packets to another port on the switch.
Port Mirroring
A physical device that allows you to intercept the traffic between two points on the network.
Network Tap
A TCP/IP protocol that aids in monitoring network attached devices and computers.
Simple Network Management Protocol (SNMP)
Computers and other network attached devices monitored through the use of agents by a network management system.
Managed Devices
Software that is loaded on a managed device to redirect information to the network management system.
Agents
Software run on one or more servers to control the monitoring of network attached devices and computers.
Network Management System (NMS)
Version of SNMP that provides integrity, authentication, and encryption of the messages being sent over the network.
SNMPv3
