- The security of GPON networks is under threat
숫자로 보기
A study presented at the Black Hat and DEF CON 34 conferences addressed the security vulnerabilities of GPON networks. The researchers discovered how data transmission over optical cables can be intercepted. In GPON networks, a feature known as Passive Optical Network causes all customers to receive the same data.
The researchers were able to read data not belonging to customers by replacing the Optical Network Unit (ONU) using equipment costing around $100. This security vulnerability poses a threat to the security of GPON networks.
To address the security vulnerabilities of GPON networks, network operators and customers need to be vigilant. Additionally, to ensure the security of GPON networks, the networks need to be regularly inspected and updated.
