The University of Tehran has developed the first national computer operating system in Iran, ISNA news agency reported.

The operating system has been installed on computers at the university and it is possible to install the operating system at other universities.

In November 2012, Mehr news agency quoted a member of the board of directors in Iran's Telecommunication Infrastructure Company Mohammad Taher Shams as saying that Iran will launch an improved secure internet to prevent cyber-attacks.

Iran's IP network, IPMPLS, will provide various services in IP, MPLS and VPLS and a secure internet. "The network's most important aim is to prevent domestic and international cyber-attacks," he said.

Earlier, Iran announced that it has taken all necessary steps to create the Halal Internet network.

The Iranian net consortium has already been established for this purpose, Iranian IRNA state news agency quoted the country's Deputy Vice President for Economic Affairs Ali Agamohammadi as saying.

The Iranian net consortium will work in the area of the fibre-optic network and Internet speed will increase once launched. "The consortium initially will render services through a fibre-optic network to 10 million users," he said.

Iran announced it had detected and thwarted a cyber-attack by the Stuxnet worm, which was supposedly created to infect Iranian industrial and nuclear computer systems in 2010.

The Stuxnet worm first identified by Iranian officials in June last year, is a malware designed to infect computers using Siemens Supervisory Control and Data Acquisition (SCADA) - a control system favored by industries that manage water supplies, oil rigs and power plants.
