Security Risks

I have been asked to evaluate a network for security threats and provide solutions. Also I must explain these situations below and indentify them.

50 users on a network:

By having these many users it would be hard to get track of every user and protect them from unwanted viruses. Network licenses only provide several users and if you use more than that it is illegal. Also by having this many users it could lead to a fault in the network and can cause the users to lose data.

No log on to the network:

By not having No Log on to a network people can access your internet and be able to use it with out you knowing. If something goes wrong with the network or file server the whole network will be unable to work properly. A user can log on to a computer anywhere on the network and access their work files from the file server.

Staff are ‘allowed’ to install and remove software:

By allowing staff to install or remove software can lead to the software being damaged or not working properly. Staff could not realize what they are doing and installing the wrong software this could lead to hackers or viruses. You should check that your staff knows what they are doing incase of this happening.

Data back up tapes:

You would need to have a back up data just incase your data gets hacked so then you will be able to access it again. If you have a back up data they must be kept in a secure box so that nothing can damage it, no one can access it and it must be updated at least every week. If you do not keep your data back up save people can access it and access your personal information for e.g. bank details, Name and addresses. This is called data protecting law this is identity theft. It is against the law to use other people’s personal information. 

The possible threats too a data stored in a system is that it could be hacked by a virus and it could be in danger of losing the data. You must have good antivirus software to be able to defend your data.

The effects of having poor practice can lead the company losing all of there data furthermore the company can lose their business and can be fined by not protecting clients personal information.

No firewall is in place:

A firewall is a software or hardware that protects you from viruses. If you do not have firewall you are open to viruses and this can lead to people accessing your information. The reason why you should have firewall is that you can defend against unwanted viruses and you are able to protect your personal information.

No restrictions on internet access:

By having no restrictions on the internet you are open to viruses, worms, adware, and trojans. If you are hacked by any of these viruses you are in danger of people accessing your personal information.  Also this can lead to your computer being non- responsive or not working.

Downloads are not monitored:

Downloads that are not monitored can lead to viruses hiding behind the download and being able to disguise itself. This can easily happen if you do not keep your downloads monitored.

IP address log is not kept on sites that you visited:

When a IP address log is not kept on sites that you visit this means that you will be in danger if you click on there link this can lead to Spyware, Trojan and other viruses hacking your computer.
