Israel Urged to Strengthen Undersea Fiber Optic Cable Security Amid Rising Sabotage Threats

Israel faces a critical vulnerability in its digital infrastructure due to potential sabotage of undersea fiber optic cables, which are essential for the country's high-tech exports and global communications. These cables, spread across the seabed, serve as vital economic lifelines, and deliberate damage could severely disrupt Israel's connectivity and economy. While recent damages have been attributed mainly to accidental anchor drags and maritime disruptions linked to the Red Sea conflict, Western intelligence agencies suspect intentional attacks by Houthi rebels in Yemen, supported by Iran. The ongoing conflict complicates repair efforts, and threats from hostile actors persist.

The United States and Europe are actively deploying naval forces in the Red Sea to protect shipping lanes and communication routes from terrorist or state-sponsored sabotage. Israel, described as a "digital island," cannot afford to rely on a few regional chokepoints for data transit. Experts recommend accelerating projects to diversify cable landing points through alternative maritime routes and partnerships with Mediterranean allies such as Cyprus and Greece. Additionally, Israel should establish a terrestrial fiber optic link with Jordan, leveraging existing energy cooperation and political ties to enhance connectivity diversity.

Satellite communications, while important as a backup, cannot replace the massive bandwidth capacity of undersea cables. Israel must also develop a resilient network architecture that allows instant rerouting of data traffic in case of cable disruptions. Critical government and defense agencies require pre-positioned high-capacity satellite terminals to maintain operations during emergencies.

To deter and detect sabotage, Israel should employ advanced maritime sonar, autonomous underwater drones, and intelligence sharing to monitor suspicious vessels near its economic waters and cable routes. The Israeli Navy’s fleet of submarines, including future deliveries, can play a key role in surveillance and intervention, especially in shallow waters where cables are most vulnerable. However, continuous physical monitoring of thousands of kilometers of cables remains a logistical challenge.

Innovative solutions like distributed acoustic sensing, which uses the cables themselves as sensors to detect underwater disturbances, could provide early warnings of tampering. Ultimately, deliberate attacks on undersea cables may be considered acts of economic warfare, requiring clear military deterrence policies against both state and non-state actors. Given Israel’s deep technological and economic ties to the United States, which remains the global data communication hub, securing these undersea networks is paramount for national security and economic survival.
