Task -2

In this stage I will describes Network Computer/Thin-client with an example and also describe benefits, drawbacks of thin-client. It has been describing Network infrastructure of one branch office and also comparing of two different solutions offered by two different commercial vendors.

Thin-client:

The Network Computer/thin-client involves connecting to the Network Computer Server and thin-client software and some hardware device with the server side using a highly efficient network protocol. Thin-client structural design enables server-based processing and support for mission-critical, web-based and other custom application across any type of connection to any type of client hardware, regardless of platform.

Benefits of thin-client computer:

User cannot load their own applications or change configuration settings without the administrator's permission.

Easy to backup and restore

Licensing is simpler to manage; Software need not be installed on a user's PCs 'just in case'.

It can save device additional device cost

Networking cost also less from other systems

Easy distribution

Facilitates 'hot-disking' or working across various sites.

Drawbacks thin-client computer:

Poor response times

Less robust transactional support

Resource loading

It is not possible to use floppy or CDs on the client machine with a true thin-client solution.

Poor multimedia performance.

Bandwidth issues.

Reliance of the server.

Network support infrastructure required for Thin-client computer:

Network computer (Network Server)

Thin-client(s)

Web server

Network Switch

Rom

Wire cables required for the thin client network connection

PXE enabled Network Interface Card (NIC) for the thin-client computer

Display monitor required for the thin-client computer

Comparison Between two different commercial vendors:

Compare topics

Linux

Microsoft

Cost

Linux thin-client computer implementation cost cheaper than others

Microsoft Windows thin-client computer implementation is very expensive

Security

Linux thin-client provide strong security

Microsoft Windows thin-client not provide strong security

Interface

Linux thin-client interface not so good looking

Microsoft Windows thin-client interface is so attractive looking

Multitasking

At the same time can run many program

Microsoft Windows thin-client not provide this facilities

Multiple user support

Multiple user can access at the same time

Not support multiple user at the same time

Summary:

In this task I have described thin-client with an example, benefits of thin-client computer, drawbacks thin-client computer, network support infrastructure required for thin-client computer and comparison between two different commercial vendors.

Task-4

Any organization network must be secured because at anytime virus can attack the network.

Virus is the major threat for any organization network. Like others this Organization need network security policy.

Described different types of virus:

Trojan horse:

In computers, a Trojan horse is a program in which malicious or harmful code is contained inside apparently harmless programming or data in such a way that it can get control and do it's chosen from of damage, such as ruining the file allocation table on your hard disk. In one celebrated case, A Trojan horse may be widely redistributed as part of a computer virus. (http://searchsecurity.techtarget.com/definition/Trojan-horse Date: 16/07/2012)

Worms:

Computer worms are malicious software applications designed to spread via computer networks. Computer worms are one form of malware along with viruses and Trojans. A person typically installs worms by inadvertently opening an email attachment or message that contains executable scripts. (http://compnetworking.about.com/cs/worldwideweb/g/bldef_worm.htm Date: 16/07/2012)

Viruses:

A virus is a small program that embeds itself into other programs. When those other programs are executed, the virus is also executed, and attempts to copy itself info ore programs. In this way, it spreads in a manner similar to a biological virus. (http://hitachi-id.com/concepts/virus.html Date: 16/07/2012)

The major network security issues:

Ensuring that only authorized personnel have access to the network infrastructure - wiring closets, networking devices, etc.

Security devices such as firewalls and anti-virus software

Data encryption systems where data is transmitted through areas that are not controlled by company

Data backup regimes, including the use of off-site backup

Training staff in the safe and secure use of the equipment they have access to

Security Policy:

Network must be password protected to prevent unwanted attract.

Only network administrator can change access permission.

No access without authorized personnel.

Password or other information must be encrypted when during travel.

User must have minimum knowledge about computer security.

Only a single network communications device should be attached per Ethernet jack. If additional jacks are required, a cabling request must be submitted to information Technology Survives (ITS).

Physical access to infrastructure network switching equipment is not permitted without specific authorization of ITS

Summary:

I have successfully completed my investigation about different types of virus, the major network security issues and security policy.

Summary of the project:

I have completed my investigation on Characteristics of Linux thin-client, Characteristics of Linux thin-client and Microsoft Windows thin-client, Total cost of ownership, Benefits of thin-client computer, Drawbacks thin-client computer, Network support infrastructure required for Thin-client computer, Comparison Between two different commercial vendors, Described different types of virus, The major network security issues, Security Policy. After all I have found that Linux thin-client is more reliable, most secure and also low price. So I am requesting to my superior to implement Linux thin-client for this company.
