1. Year 9 Autumn Assessment Computer system/Information security-Planning, Communicating, Information. By Louis Smith-Lassey 9k 9Y1

2. Computer system Security/Performance problems.  Security issues that threaten system performance:  While on the computer system at work certain things may harm the way your system performs  For Example:  Crashing: when there are too many people on the computer and using the network then that would cause the computer crash, because too many computers are trying to the sort of the same thing at the same time. However your computer could also crash because your internet connection could be too slow (not enough memory) and with everybody trying to use the internet the system will crash.  Phishing: Phishing will happen when people will access your computer and try and take your personal details. This can take place by hackers sending you a spam email which will pose as your bank and ask you to update your personal details. However this is a fake email and the creators will then take you details and use them against you.  Hacking: people will manage to access your computer without authorisation then they will be able to maybe put a virus on you computer and use your personal details. This is known as hacking.

3. Computer system security/Performance problems.  Security Precautions:  There are many precautions that the company can take in order to prevent the system from being threatened by any form of virus.  For example:  Using up to date anti virus software, by using anti virus your computer system will not be at any threat of getting a virus unless you would for your system to get one.  One of the ways that your anti virus software will help you is that you can run regular scans on your computer. Once the system has finished the scan it will be able to tell you if it has detected any viruses on your computer, if it did it the software will hopefully be able to rectify the problem.

4. Data/Information security issues  Identify threats to the whole use of technology.  This slide will tell about the threats you own personal computer can get.  For example:  People who would want to access your details would send you emails that will have a virus that will infiltrate you computer system and damage it.  Another that may threaten you personal computer is if you go onto a new website that you have never heard of this website may be infected with viruses or Trojan horse viruses which are a different type of virus which infect your computer through random windows opening asking you to open them.  So to prevent these non reputable websites you should activate the pop up blocker on your internet provider what this will do is recognize that you are on a non reputable website and freeze the web site and tell that pop up blocker blocked it.  Lastly another way to protect your computer from threats is not opening inappropriate websites, most if not all of these websites have viruses on them and by not opening them your computer will be safe.

5. Data/Information security issues  Appropriate Precautions  Just like the security precautions I explained in my earlier slides here are the appropriate precautions you need to take to protect data and information on your computer system.  For example:  It is good to use anti virus software, however if that software expires you have to purchase some new software, because once it has expired it will not be able to protect your computer system from viruses or malware which is short for malicious software a main type of virus.  Just like the slide before if you cannot afford any anti virus software for a few months then a way to prevent viruses is to not go on inappropriate websites.

6. Suggestions and guidelines to help staff in the company use the computer system more safely.  Guidelines and procedures.  A guideline for the company to prevent the companies computer system from getting a threat of a virus. Is to install a piece of software that will prevent staff from going on virus infected websites that will let viruses into the system. By doing this your computer system will at a lower risk of getting any form of virus (malware, Trojans, Phishing), because it has prevented (e.g. Pop up) your staff from going on unhealthy websites.

7. Suggestions and guidelines to help staff in the company use the computer system more safely.  This is another solution as to how staff of the company can prevent threats of malware and viruses into the companies computer system.  Once a member of staff has finished a piece of work they would normally save it, however they should also save that piece of work to another location e.g. a USB (memory stick) this is called backing up files.  However saving your work to another location does not mean saving as a different file it means saving to different location e.g. USB stick or emailing to your self.  By saving your work on a USB stick means that it is portable so you can transfer to different computers, but you can also save work onto USB’s in case your computers memory is full.
