Bezpečnostní rizika v optických přístupových sítích

Abstract

This bachelor thesis deals with security of optical access networks, specifically its passive optical networks variants (PON). The first part describes the characteristics of technologies, both current and future generations of the PON networks, including possibilities of their securing. The second part describes the security risks of systems based on the method of time division multiplexing TDM-PON, wavelength division multiplexing WDM-PON and security mechanisms used to avoid them. The aim of the work in the practical part is to verify in laboratory conditions security risks associated with the deployment of the WDM-PON technologies.
