Network Intrusion Detection (ID) attempts to detect diverse security attacks using a security system to monitor, analyze, detect, and respond to threats.In Software Defined Networking (SDN), ID that typically occurs at the controller is influenced by application policies and is advantageous over generic networking due to the network and flow awareness of the controller and the threat response capability of the controller itself.A blockchain system embodies a succession of attached blocks that implicitly maintain the purity, preserve the indisputability, and preserve the quasi-anonymity of its transactions/activities because of consensus protocols and cryptographic algorithms.Being the front-line reviewers for BCcentered ID in SDN, we group blockchain roles in ID in three ways and elaborately examine those pertaining to ID techniques and ID approaches, blockchain components, attack detection, network components, and so forth.We stacked a preliminary sample of 97 paper sources by sifting through the articles for selection guidelines inquired from virtual libraries, applying an elaborate and overtime procedure.Centered upon this examination, blockchain-centered ID in SDN involves collaborative ID by engaging smart contracts while storing data required for threat detection in blockchain, off-chain ID while applying blockchain for trust management, and applying blockchain for authentication and secure data storage for off-chain ID.Elaborate examination divulges that from blockchain-centered SDN ID proposals, 48.9% apply blockchaincentered secure storage for off-chain ID, 91.2% engage systematic blockchain architecture, 8.9% apply PoAuthority consensus, 100% online, 75.5% active response, 71.1% fully distributed, and 57.8% apply hybrid host and networkcentered ID, with DDoS being the most dominant (17.8%) specific attack category.Finally, we explore the potentials and hardships of the schema of blockchain-centered ID in SDN and then supply insights to overtake them.
