Answer - Network Security
Introduction
Network security is combination of programs installed in a workplace so that the documents and security of the employees are restored.
Network security is constructed to safeguard the integrity and usability of working network with the help of hardware and software applications.
Firewall
It is a device connecting the organization's internal network to other network.
It can filter the incoming programs destined for a particular server like HTTP.
It can also deny its access for a particular host of the organization.
Examples include software firewall, proxy firewall etc.
Use of Firewall
It is a kind of intrusion detection policy that is specific for every organization.
They can easily be configured to traffic such as SNAP and POP that help it to access email.
They block spam email.
Help to restrict access for specific services for instance, they can prevent their access to telnet.
Intrusion detection systems
Just like firewall the Intrusion detection systems helps in monitoring cyber traffic sensing any malicious activity.
It also raises alarm to use when such suspicious activity is tracked.
Uses
NIDS can monitor both outbound and inbound traffic to all the devices of the organization.
HIDS is beneficial over NIDS in detecting anomalous packets originating from slanderous traffic.

Demonstration of the systems in HIM network
IDS have sensors to detect behavioral activities or signatures. If the particular activity is unable to match with the recorded one, it determines suspicious activity.
In case the signature matches, IDS transfers to the next phase in order to slash source IP. This notifies the user by the alarm (Milenkoski et al. 2015).
Organizational policies for using intranet and internet
Intranet helps to do announcements on administrative data.
Communicate for training sessions and professional development.
Circulate policies of the administrative department.
Circulate clinical documentation of patients to doctors.
Record enrollment date of the patient.
Place clinical orders.
Wording for policies for internet and intranet in healthcare setting
Internet explorer maintenance policy: the policy allows configuring internet connection with other policy settings. The policy is user based hence restricts user from altering the setting (Milenkoski et al. 2015).
Policy mode: settings are adjusted each time or processing workstation.
Preference mode: settings are adjusted single time to work station.
Discussion of one policy
Clinical use of intranet provides static relevant clinical data to clinician hence participants in direct patient care.
The clinical data are extracted by browser benefiting the clinician to have a quick check on their patient information (Gendreau and Moorman, 2015).
Conclusion
Both the programs IDS and firewall are aimed for securing network still they have minor differences within.
Firewalls restrict network access preventing intrusion by not signaling any attack. On the other hand IDS detects malicious intrusion and raise alarm.
