The prototype of the Working Group on Network Security was created by a former GTER working subgroup on security, which was presented at Comdex-SP, in 1996. A month after its launch, the article “Towards Creating an Internet Network Security Department in Brazil” was published.
In June 1997, CERT.br (former NBSO) was created and its activities, which at the time were based on the work of volunteers, enabled the creation of the CT-Security, on February 11th, 1998.
Until April 2002, under the coordination of Prof. Dr. Pedro Vazquez, from IQM/Unicamp, the GTS was composed of two subgroups: backbones, coordinated by Ricardo Maceira (Embratel), whose main objective was to discuss the issue of security for networks connected to the Internet from the perspective of backbone providers; and providers, coordinated by Nelson Murilo (Pangeia) and Rubens Kuhl Jr. (UOL), which focused on security aspects related to companies which provide access to the Internet.
Currently the GTS is coordinated by Prof. Dr. Adriano Mauro Cansian (Unesp) and supported by CERT.br.
