Internet Security: Discuss the Issues of Data Security, System and Communications and Risks of Data Communications
DATA SECURITY COMPROMISE: Every data transaction which takes place on theinternet basically consists of three things - a client, a link and aserver. This model can be applied to web commerce, to health careorganizations, to government websites, basically to anyone who is offeringinformation over the world wide web. Each section of this model can have Clients are able to find and access a number of web sites via searchengines. However, it is important that each client understand that the website they are accessing may not be 1) active 2) secure 3) truly thebusiness they feel they are engaging in commerce with. A good example ofthis may be websites that mirror more popular websites by names that aresimilar or by hackers who are able to simply copy the original web site andrename it for their own means. Also, many websites may belong to companieswho cannot be trusted and clients take a risk when providing the creditcard numbers to unknown sites. Clients must be aware of whether the siteis genuine and that the company who offers the site can be considered to betrust worthy. As there is very little in the way of legal precedentsurrounding transactions on the world wide web, it is
Some systems have been developed to help clients and customers verifythat the business they want to deal with is truly the site they areaccessing. Probably a more true distribution could be assessedbased on the population of internet users per country. Some companies have gone to great lengths to ensure that theirdomain names are "bracketed", meaning that their domain and any likelyvariations on the same are registered so unscrupulous persons cannotdevelop like sites with similar names. This can causereal impact on a company who uses their network in a heavy manner. Far from being a fantasy ofclassification, federal legislation is actually in place protecting certaintypes of data in just such a way, such as medical data (HIPAA) and customerfinancial data (GLB)(Junkaar,2003). Sensitive data transmission must be sent via a secureencryption system and it is best when pages which contain or acceptsensitive data be made non-cacheable. RISKS TO DATA SECURITY: In this section of the paper, we will discussdifferent types of risk to internet security and methods which can be usedto combat them. No one who listens to popular media can have missed thenews about different viruses and worms let loose upon computer networks. A worm is a software that usually uses computer networks as it'shost, finding holes in the security networks and hiding there, thenscanning for holes in other networks which will allow it to copy itself toanother machine and to reproduce there as well. Email is a pathin and out of a data network, and as such is the perfect vehicle for abroach of computer security. Obviousmeasures should also be taken such as password security, serverconfiguration which allows the least privilege and separate development andproduction systems(Krishna, 2002). A computer virus is a small piece of computer software that uses realprograms to replicate itself. Web site security standards are unregulated, although with theburgeoning web based commerce boom, web sites are more and more expected todevelop high standards for information security. It is bestfor data security when sensitive information is periodically removed fromthe server. Companies such as TrueSite and theBetter Business Bureau On line have also gotten into the business.
