- The world wide web has tons of resources that can facilitate your work and make you more productive. Unfortunately, there are also many websites containing material that are inappropriate, illegal, or even dangerous. For this reason, content control mechanisms have been employed in the University network. This ensures network security, employee productivity, bandwidth savings, and helps the institution avoid any possible legal liabilities.
- Security concerns - Websites have become a vehicle for infecting users with malware that steal confidential information or hijack computers to distribute spyware or viruses. Sites which are classified as possible hosts of malware are tagged for blocking.
- Minimizing liability exposure - Websites which offer downloading of pirated content or viewing pornography (especially child pornography) have serious legal implications and are not allowed.
- Employee productivity - The computing resources of the University will facilitate work-related activities which include opening the Internet for research, communication, and collaboration tools. Websites which offer occasions of excessive non-productive Web surfing are included in the banned list.
