Iran Internet infrastructure

The organization, known by aliases including Iran Internet infrastructure and Iranian Internet Infrastructure, is responsible for the management and security of the nation's digital communications networks. Its core function is the operation and defense of Iran's internet infrastructure, encompassing both fixed-line and mobile networks. A central component of its defensive capability is the 'Digital Fortress' (DZHAFA) cyber-defense mechanism, which is designed to repel large-scale cyber attacks targeting national connectivity. The existence and activation of this system indicate a focus on protecting critical national infrastructure from significant disruptive threats. The organization's operational scope is national, as evidenced by its response to incidents causing nationwide internet disruption. Its role is inherently tied to national cybersecurity and the continuity of digital services within Iran.

The organization's capabilities and operational context were highlighted during a major incident on February 8, 2020. A highly distributed denial-of-service (DDoS) attack caused a severe nationwide internet disruption, reducing connectivity by approximately 75% for seven hours. In response, authorities activated the DZHAFA system to neutralize the threat, a measure which officials stated was successful. This defensive deployment followed prior uses of the DZHAFA mechanism against state-sponsored cyber operations, including previous espionage attempts on government systems. While officials denied any state involvement in the 2020 attack, the incident demonstrated the organization's role in executing large-scale cyber defense. The disruption occurred coincidentally with unrelated delays in a satellite launch, though no direct link was established between these events. The 2020 event remains a key reference point for the organization's defensive posture and the scale of threats it is designed to counter.
