Network Concepts Flashcards
CSMA/CA
Carrier Sense Multiple Access/Collision Avoidance
It is a media access control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium, such as an electrical bus or a band of the electromagnetic spectrum.
CSMA/CD
Carrier Sense Multiple Access/Collision Detection
It is a media access control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium, such as an electrical bus or a band of the electromagnetic spectrum.
WAF
A Web Application Firewall protects web applications by monitoring and filtering traffic
WPA
WiFi Protected Access
DLP
Data Loss Prevention
UTM
Unified Threat Management
OSPF
Open Shortest Path First
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS).
OSI
Open System Interconnection Model
TPM
Trusted Platform Module
ACL
Access Control List.
Operates in levels 3 and 4 of the OSI model.
STP
Span Tree Protocol
SNAT
Source Network Address Translation or Static Network Address Translation
NAT
Network Address Translation
PAT
Port Address Translation
IDF
Intermediate Distribution Frame
ICMP
Internet Control Message Protocol
GSM
Global System for Mobile Communication
GSM (Global System for Mobile communication) is a digital mobile network that is widely used by mobile phone users in Europe and other parts of the world.
TDM
Time Division Multiplexing
Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time in an alternating pattern
CDMA
Code Division Multiple Access
Everybody communicates at the same time. Each call uses a different code. Codes are used to filter each call on the receiving side.
PSTN
Public Switched Telephone Network
ARP
Address Resolution Protocol
Banner Grabbing
When a malicious user gains access to an open port and uses it to probe a host to gain information and access, as well as learn details about running services
Sticky MAC
Port security feature where dynamically learned MAC address are retained when an interface comes back online
SIEM
Security Information and Event Manager
Software that can be configured to evaluate data logs from IDP and IPS firewalls and proxy servers in order to detect significant events that require the attention of IT staff.
