VI. Network Security Measures and Countermeasures
To manage the network vulnerabilities which identified before, we need to set up our network security. The main purpose of providing network security is to keep the data confidentiality of the network, network integrity, and availability of the network to be used. Building our network’s security doesn’t mean totally eliminate all possible threats that may harm our network. Network security just minimizes the possibility of such threats to occur. Additionally, we can’t build our network security just by setting up one firewall and leave it to take care of the entire network’s security problems; it’s definitely not like that. Building our network security means that we need to set multi security devices and software which work in a coordination with each other in order to provide a well protected network.
We can start to set up our network’s security by considering our network’s vulnerabilities. So, here are some things we will do to build our network security:
1. Physical Security
2. Access Control
3. Operating System Security
4. Virus Protection
5. Internet Security
1. Physical Security
Physical security is aimed to prevent Click here to read the full post…

Hi! This is my C1006 Computer Networks assignment that I do in Term 3, 2007, in Informatics Computer School Singapore. How is the new assignment looks like? Do you have any questions? just ask me and I will try to help you.
The Question:
You have to design a small office network with less than 10 desktop computers. You have to link all the computers to a network printer and fax. For each part of the network, as shown in your diagram, write a few paragraphs describing the part. If you choose a workgroup or client-server environment, then you have to explain in your report. Your company Internet uses a high speed DSL Internet connection. You also have to explain the vulnerabilities and security measures in your network and Internet. Lastly tabulate the cost of the network.
Notes :
The diagram must show the computers, Internet connection, and physical layer items (e.g. wires, hub, router, firewall etc, if appropriate). The diagram should be an original drawing done by you using computer drawing such as PowerPoint (although you can use clip art and real pictures of components as part of the diagram if you wish).
