Pornography by definition • The word pornography has evolved considerably from the Greek language. In Late Greek the word 'pornographos' was used to describe writing about prostitutes and encounters with prostitutes (Dictionary.com 2004). • The Merriam Webster Dictionary of Law (1996) defines pornography as material that depicts erotic behaviour and is intended to cause sexual excitement. • The Webster New World Encyclopedia (1992) defines pornography as obscene literature, pictures, photos or films of no academic merit, intended only to arouse sexual desires.
Pornography by definition • The Webster’s New World Encyclopedia and the Merrian Webster Dictionary of Law focus on different themes. • The Webster’s New World Encyclopedia focuses on “obscene” content which is the lowest form of pornography. • While the Merrian Webster Dictionary of Law focus on “erotic” content which is seen by some psychologists more acceptable form of pornography. • The problem is that there are many forms and definitions of pornography.
Pornography as an online risk Access to pornography can pose the following problems for an organisation: • Legal liability • Loss of production to non-work related content • Loss of bandwidth.
Pornography as an online risk 1. Legal liability Employees can be directly or indirectly liable for sexual harassment based on a hostile work environment. • Direct liability is classified when the employee’s supervisors sends pornographic content that is perceived to be offensive by the employee. • If the wrongful conduct is directed at the employer as he/she is responsible for the conduct of the supervisor (Overly 2002).
Pornography as an online risk • Indirect liability results when the employer fails to restrict or correct activity that creates a hostile working environment. • This is commonly what happens to employer’s who do not have a content filtering solution as well as an effective acceptable use policy (AUP) in place. It is necessary to take the right steps to prevent such liability.
Pornography as an online risk 2. Loss of productivity • Around 20% of employees view content of pornographic nature during work hours. • One in five men and one in eight women admitted to using their work’s Internet as the main channel for accessing sexually explicit material (Secure Computing Corporation 2005).
Pornography as an online risk A survey conducted by Valt.com revealed how often employees used the corporate Internet facilities to surf non work related sites (Witzke 2002): • 34.9% claimed “a few times a week” • 38.1% claimed “a few times a day” • 14.6% claimed “I surf the Web constantly” • 12.4% claimed “never, that’s unethical”.
Pornography as an online risk 3. Loss of bandwidth • In some organisations network surveys have found that P2P file sharing networks (containing pornography) have been responsible for consuming up to 80% of the bandwidth. • This can have a crippling effect on the networking resources.
