Assignment 4

I have been asked to evaluate a network for security threats and provide solutions. This company has no security in place and I can advise numerous things that will help improve and keep the company safe.

The business has the following problems:

1.    Unrestricted internet access

2.    Being able to install and uninstall software

3.    Data tapes are kept in plastic boxes above the server

4.    The sites that are visited are not recorded

5.    Downloads are not recorded

6.    No firewalls

7.    Entrance doors are not protected
8.   No logon  

Unrestricted internet access is a problem in businesses because workers may get distracted from there work and then spend all day on websites that may have nothing to do with there work and also sites that are inappropriate. There is different software that could be used such as bluecoat proxy SG, this will limit the sites that employees can access thus

improving work productivity and they will be more efficient.

Employees should not be able to install and uninstall different software because this is something that everyone uses just because one person doesn’t use a particular application this does not mean that someone else in the company does not use it. Software may be installed that has no relevance such as Skype.  

Data tapes should not be kept in plastic boxes because they could be destroyed easily, they should be kept in a waterproof and fire proof box also they should not be kept in a safe place where no one can take them preferably a room which has limited access. The data tapes are also only back up once a month, this should be done every month becuase is a tape is lost, alot of data will be lost.

 

A firewall is software such as barracuda spam and virus wall or avenquest, it stops email viruses and phishing scams. It is to make sure that your computer is secure from things that may brake it.

Anyone can walk into the business even those who do not work there. It is recommended that there is restricted access so only certain people can get in, or other people have to be allowed in. if there is no security anyone could go in and steel equipment, this would result in the company having to purchase new things so a keypad would be recommended as it may save them money because the company would have to keep buying new things, also the sever could be dmages and also data would be lost.

Website that the employees visit should be monitored so that the company no what they have been on they can also check by the persons log in who it is that may be viewing inappropriate or non relevant material.  

Logons should be used so that no one can log onto you account or use the computer network that aren’t involved in that collage or business, it is to keep your information secure. It means that you have your own area of work were files can be saved and no one can access them and change or delete them. You may be a certain level in the company which means that not all things should be visible to you such as finance if you are nothing to do with that.

Records of what people have been downloading should be kept to see if anything that was downloaded contained virus’s that would harm the computer, therefore this could be dealt with immediately and minimize the harm of the computer.
