Unit 1a Flashcards
This refers to activities, methods, procedures, and tools pertaining to operation, administration, maintenance, and provisioning of networked systems
Network Standardization
This allows the monitoring of events on a system and maintains logs about application, security, and system events on a computer. This starts automatically when the computer starts.
Windows Event Viewer
Records events logged by system components
System Log
Records events logged by programs
Application Log
Records security events
Security Log
Significant problem such as loss of data or loss of functionality
Error
Event that might not be significant but may indicate future problems
Warning
Event describes successful operation of an application, driver, or service
Information
Audited security access attempt that succeeds
Success Audit
Audited security access attempt that fails
Failure Audit
Provide real time collection of resources used for CPU, Disk, Network, and Memory
Task Manager
Shows status of programs running on computer. Can end, switch to, or start program
Application Tab
Shows information about processes running on a computer. Can change priority as well as terminate process
Processes Tab
Displays dynamic overview of computer’s performance
Performance Tab
Displays graphical representation of network performance. View the quality and availability of a network connection and whether connected to more than one network
Networking Tab
Displays users who can access computer as well as session status and names
Users Tab
Goal is to detect, log, notify users of, and (to extent possible) automatically fix network problems to keep network running effectively. Perhaps most widely implemented of ISO network management
elements. Allows administrators to proactively correct problems on network
Fault Management
Process of collecting alarms, which occur when something happens on a networked device
Passive Fault Management
Uses utilities (ping, traceroute) to address issues when a device fails and an alarm not sent to management tool
Active Fault Management
Common tools/commands used to analyze network and configuration setup
Fault Isolation Tools
Commonly used to measure voltage of batteries or electrical outlets. Combines the functionality of three instruments into one: Ammeter, Voltmeter, and Ohmmeter.
Multimeter
Measures current
Ammeter
Measures potential difference between two points
Voltmeter
Measures resistance
Ohmmeter
This connects to one end of a cable and sends a signal down the cable.
Tone Generator
This detects a signal sent by a tone generator providing the ability to trace wire in a group of bundled cables
Probe
Looks for breaks or other imperfections in a cable. Sends out pulses of electricity to light (depending on system used) at regular intervals. Measures amount of time takes for pulse to reach break and bounce (reflect) back to device
Time Domain Reflectometer
Goal is to monitor network and system configuration information so affected hardware and software can be managed and tracked. The subsystems to this may provide ability to initialize, reconfigure, operate, and shut down managed devices
Configuration Management
Goal is to measure various aspects of network performance so internetwork performance can be maintained at acceptable levels
Performance Network
Goal is to control access to network resources so network cannot be sabotaged and sensitive information cannot be accessed by those without appropriate authorization
Security Management
Any person, group or forces that opposes or attacks
Adversaries
Includes traffic analysis, monitoring of unprotected communications, decrypting weakly encrypted traffic, and capture of authentication information
Passive Attack
Includes attempts to circumvent or break protection features, introduce malicious code, or steal or modify information
Active Attack
Consists of regular type individuals attaining close physical proximity to networks, systems, or facilities for purpose of modifying, gathering, or denying access to information
Close-in Attack
The goal to measure network utilization parameters so individual or group usage on network can be regulated appropriately
Accounting Management
Permits workstation to capture and monitor network traffic going to and from machine on which it is being executed
Network Monitor
Transmits, captures, decode packets, and provide statistics based upon real time network traffic
Protocol Analyzer
The tone generator and probe are components to this, it is commonly referred to as “fox and hound”
Cable Toner
