Systems Security: Threats to computers

Extracts from this document...

Introduction

* SPAM email - Unwanted mail that can cause stress, slowdowns and can mess with your hard drive. To deal with a current situation of SPAM, you can acquire SPAM removal software, and use that to search your system and mail applications to remove all unwanted SPAM. To prevent future cases of SPAM, install SPAM filtering software, alter ports and keep your email private without sharing it to unknown sources. * Viruses - These can infect a computer and corrupt, delete and alter personal, general, and system files. To deal with a current situation of this, try running anti-virus software. If it is unable to run, try and load it from a portable device. If that doesn't work, use search engines on the internet to gain knowledge and possible solutions to the problem at hand. If the virus has stopped any possible access to the internet from your computer, then use another source to search the internet, e.g. a friend's computer, or an internet-enabled library. To prevent any future viruses from infecting your computer, acquire anti-virus software, steer clear of unknown sites and material, and also use software that blocks unwanted IP's from your network. ...read more.

another HDD, or an external hard drive. * New updates to an Operating System (such as Microsoft Windows Service Packs or similar) - A new set of updated system files could overwrite needed files and could make the computer unstable. To deal with this kind of situation, you could contact the provider of the updates and get any information from them concerning your new system problems. Also you could analyze previous experiences from users who have applied the updates before by using search engines on the internet. To prevent any future cases of this, don't install updates to your OS without checking details such as the system requirements, and analyze other users' experiences and outcomes with the updates you're thinking of installing. * New updates to Applications (such as a new version of Microsoft Office) - An application can get updated to fix bugs and errors, however this can make files that previously worked incompatible with the new version. To deal with a current situation like this, you could contact the provider of the updates and get any information from them concerning your new application problems. ...read more.

Conclusion

* Theft - The whole system can be stolen which obviously means physical access is lost. To deal with a situation like this, contact the authorities, and let them know what has happened. Also analyze the area where your computer was stationed for any evidence of the theft, and note down anything that could possibly trace back to the thief. To prevent future cases like this, you could place your computer in a higher-security location, with more safety. Also, install security measures such as cameras, and guarding for your computer. On a further note, you could install software that could lock or possibly destroy your data/components if the computer is stolen again to render the stolen property useless to the thief and to protect your data from unwanted people. * Damage to keyboard, mouse, power/network cables or monitor - These are required to use the operating system properly, if these aren't present, then access is lost. To deal with a situation like this, replace the damaged parts, or take the parts to a specialist. To prevent future cases like this, get more reliable parts, and make sure they remain in suitable locations and conditions. ?? ?? ?? ?? John Bonham Unit 15 - Systems Security 1 ...read more.
