An Overview on Security Issues in The Optical Access Network

摘要

Security threats has become a major issue in today's networks including optical access network. Due to its high aggregated bit rate feature, a short attack can possibly affect many users due to high number of bits involved. This paper provides an overview of possible attacks that can occur in the optical access network. It describes and discuss the vulnerability of the network such as eavesdropping, Denial of Service (DoS) attack and spoofing attack. Possible countermeasures from physical and MAC layer approaches are also discussed.
