name: OAM
full_form: Operation, Administration and Maintenance
context: In case that OAM server is placed inside the operatorâs network, i.e., behind a SeGWï¼ OAM traffic could be protected hop-by-hop. Between H(e)NB and SeGW, OAM traffic is protected by IPsec tunnel. Network security mechanisms could be used to protect OAM traffic between SeGW and OAM server when the path from SeGW to OAM server is considered as insecure. OAM traffic could also be protected end-to-end. A secure tunnel, e.g. TLS, is established between H(e)NB and OAM server. OAM traffic is protected by such a security tunnel. In case that OAM Server is placed outside the operatorâs network, i.e., the H(e)NB is directly connected to the OAM server, OAM server is exposed to attackers located in insecure network. Though secure tunnel, e.g. TLS, could be used to partially protect OAM traffic and prevent OAM server from being attacked, the risk of placing OAM server outside the operatorâs network is higher than that of placing the OAM server inside the operatorâs network. Robust security
description: Operation, Administration and Maintenance (OAM) refers to the processes and systems used to manage and maintain telecommunications networks. This includes tasks such as configuration management, fault management, performance management, and security management.
explanation: OAM encompasses a broad range of activities related to network management and upkeep rather than a specific technology or protocol. Its focus on operational aspects places it under the 'Miscellaneous' category.
