The ubiquitous implementation of information and communication technologies (ICTs) is giving rise to cross-border security threats that require joint international responses. Fragmentation and growing conflict in the global information space complicate international cooperation within the UN to form a comprehensive global information security regime. Western countries actively support the formation of a cyber security regime based on Western values and promoted as a general initiative of the international community, without taking the position of developing countries into account. An alternative approach focused on securing digital sovereignty is being promoted by many non-Western negotiating platforms, among which the BRICS occupies an important place. This article aims to assess the potential of the BRICS influence on the international ICT security regime and the main directions of the association’s activities in this area. In this paper, the BRICS ICT security agenda is studied on the basis of official documents of the association’s annual summits and the main commitments made by the member countries. The discourse analysis of the strategic planning documents of the BRICS countries allows to identify their priorities in this area, and to assess the potential for the implementation of these obligations at the BRICS level. All the BRICS countries focus on ensuring ICT sovereignty. However, Russia, India, and China consider digital development and ICT security as the most important area of state policy and international cooperation. They are also more advanced when it comes to digital technologies compared to the other BRICS countries, which means they are more vulnerable. In turn, Brazil and South Africa do not consider this area as a priority, placing greater emphasis on ICT development, access to technology, and bridging the digital divide. However, all five countries are interested in solving the problem of extremism and terrorism in the digital sphere, which is also a promising area for BRICS multilateral cooperation. A study of the voting of the BRICS countries in the UN and an analysis of their participation in alternative initiatives in the formation of a cyber security regime promoted by Western countries showed the high efficiency of BRICS as a negotiating platform. Its main contribution in this respect is the development of a common position on the norms and principles of the international information security regime and their support at the UN level. Thus, BRICS can make a constructive contribution to the formation of the norms and principles of the international ICT security regime based on the principles of respect for state sovereignty, the internationalization of internet governance, and combatting to the criminal use of ICTs. An important advantage of BRICS in this area is the possibility of aggregating the interests and positions of developing countries.
