8. Making Network Secure Activities
Activities which can help to make a network secure include:
Creating a new user account with a sensible username and password,
Apply permissions to the account for group membership, restrict login hours, restrict machines can log into etc.
Create a security group and add users to it,
Create a group policy object to restrict what users have access to on a client machine,
Set authorisation permissions for the user to access a shared drive or folder on the network,
Grant the user with Read, Write and Execute access controls to a shared drive or folder on the network,
Create a password policy on the server,
Set an access control rule on the servers file wall – open up / restrict ports,
Schedule a folder to be backed up to either the NAS box or to tape,
Delete and then restore the folder from the last available back‐up,
Encrypt the data stored in the shared drive or folder so that it remains secure,
Review the physical security of the server and recommend how this could be improved,
Install Anti-Virus software on a client machine and ensure its scheduled to automatically scan the machine and update,
Install a screen saver with a password on a client workstation,
Remove a virus using Antivirus software.

9. Impacts on Loss of Network Service
You have looked at potential problems associated with network security breaches and some of the measures which can be taken to prevent them….
Impacts are the problems which occur and how they affect the organisation as a result of network security breaches

10. Impacts to Consider
For each of the impacts listed below you need to give as many examples are you can along with measures which can be taken to prevent them arising.
The impact of loss of service,
The impact of loss of business or income e.g. through loss of customer records,
Potential increased costs,
The impact of loss of confidentially,
The impact of compromised data integrity,
The impact of potential security issues caused by a viral infections, malware, Trojans, worms, spyware and adware.
You may choose to present your evidence for this task within a table or report (through Google Docs) – use the impacts above as headings.
