Networking Software & Disaster Planning - Coggle Diagram
Networking Software & Disaster Planning
Small networks can be run using existing Windows software. Larger networks need specialist network operating software.
This software has features that enable the network manager to co-ordinate the activities of all computers and devices on the network.
Examples of Network Operating Systems are
Linux
Novell Netware
UNIX
Network Management Software
This software would enable the network manager to control all the computers on the network. Some tasks the network management software would help with include:
Able to install and uninstall software
Able to monitor the use of all workstations
Ensuring the latest security patches are current and working
Keeping track of software updates and software licences
Remote Management of a Network
There are many tasks that a network manager/technician can perform on a network without leaving their own desk.
They can use remote management tools to perform the following tasks:
See which users are using the network
See if components on the network are functioning correctly
Check on Internet sites being visited
Guide users through problems
User Accounts
These are created by the Network Manager so that only people who are allowed to use the network can access the system.
The manager can create certain rights – that is only certain things can be done on the network - cannot install software etc, access certain data or folders.
Users can change passwords and desktop settings and manage their own files and work.
Network Configuration Software
Once a network has been created it is necessary to configure it to maximise its performance.
Network configuration management software enables the network manager to choose the best course of action if a network needs modifying
Benefits of using Network Configuration are:
Less network downtime
Security will be optimised
The network will be optimised and will run faster
Keeps a record of all changes to network
Easier to repair, expand or upgrade the network
Log ins and Audit Trials
Each user on a network can be given a user account and password. It is the users’ responsibility to change their password and to keep that password secure
The network manage can assign different user accounts different access rights and privileges. Some users may be given permission to change workstation settings while others may be prevented.
The account keeps a record of:
All files accessed and edited.
This system can be used to monitor staff and can be used as evidence of abusing the system or even hacking attempts made.
Internet pages visited
All documents printed
Security Strategies
Business is worried about security threats - loss of data, theft of data etc.
The use of networks exposes organisations to a range of threats Software systems can be used to reduce these risks.
Firewalls - to prevent hacking
Encryption - keeps data secret when sent over a network or the Internet - bank details etc
Virus checkers – kept up to date, can run automatically
Disaster Planning
Companies must plan for when things go wrong, hardware or software failure such as:
Hardware breaking down
Reasons for Disaster Planning
In the case of a system breakdown the company will be more prepared to get the system to work again ASAP and:
Minimise disruption to company
Minimise loss of data - Losing data can cause loss of customer confidence
Minimise loss of money - possibility of bankruptcy
Accidental damage - Deleting files accidentally.
Software bugs - Virus
How to plan for a disaster
Restoration of Data
Companies should perform a mock disaster recovery to check it works
No point taking backups if the recovery is not tested
Regular backups of data
Take discs off site in case of fire or theft.
Make more than one copy of backups are made [RAID system]
Save the work on a regular basis.
