2023 Cyber Stability Conference – Use of ICTs by States: Rights and Responsibilities Under the UN Charter

The 2023 edition of the United Nations Institute for Disarmament Research (UNIDIR) flagship Cyber Stability Conference (CS23) focused on “Use of ICTs by States: rights and responsibilities under the UN Charter”.

Nearly a decade ago, States agreed that international law is applicable and essential for a secure, stable, peaceful information and communications technology (ICT) environment. The remaining question is how international law applies to the use of ICTs by States. With the increasing frequency, sophistication and complexity of cyber threats, it is time for States to discuss more specifically how international law applies to the ICT environment.

To facilitate focused future deliberations and therefore meaningfully contribute to the advancement of multilateral negotiations, CS23 focused on the first source of international law that States agreed on as being applicable in cyberspace – the Charter of the United Nations (UN). Specifically, CS23 investigated the rights and obligations of the UN Charter applicable to cyberspace, including legal principles and thresholds related to topics such as the use of armed force; armed attack and self-defence; role and powers of the UN Security Council; and peaceful settlement of disputes.

In addition to providing a platform for the exchange of views among national experts, CS23 also featured introductory briefings from reputable scholars, adding clarity on key concepts and supporting meaningful participation of all States in the relevant multilateral discussions.

A playlist featuring all of the event’s sessions is available on UNIDIR’s YouTube Channel.
