IDENTIFYING AND SCHEDULING DDOS-APPLICATION LAYER ATTACKS IN MARINE, OIL & GAS EXPLORATION ASSETS ON-BOARD SYSTEMS LIKE PMS, SENSOR BASED DATA SYSTEMS

Abstract

For the cost effective & safe operation of ships and other marine assets it is mandatory to develop software solution tool which helps in timely maintenance with priority based to avoid both financial losses and operational downtime. Our idea is to propose concept to develop combined protection mechanisms system for Planned Maintenance system. The research is IDENTIFYING AND SCHEDULING DDOS-APPLICATION LAYER ATTACKS on onboard systems. Countering Distributed Denial of Service (DDOS) attacks are becoming ever more challenging with the vast resources and techniques increasingly available to attackers. In this paper, we consider sophisticated attacks that are protocol- compliant, non-intrusive, utilize legitimate. Application-layer requests to overwhelm system resources. We characterize application layer resource attacks on the basis of the application workload parameters that they exploit. Request flooding, asymmetric, repeated one-shot. To protect marine software-based servers from these attacks, we propose a counter-mechanism that consists of a suspicion assignment mechanism and a DDOS-resilient scheduler, DDOS Shield. In contrast to prior work, our suspicion mechanism assigns a continuous value as opposed to a binary measure to each client session, and the scheduler utilizes these values to determine if and when to schedule a session’s requests. This will be done through an integrated working of PMS and Inventory. PMS and Inventory, while performing definite tasks independently, will seamlessly integrate with each other. Further the installations will reside in the vessel, office and other office nodes, where information can be viewed and updated depending on your network of vessels. In office, the Inventory-PMS package will function in a client –server mode and in a single terminal on the ship with LAN for the purpose of accessing Internet. All the database updating and back-up maintenance shall be shown into the system to enable the user to do the database management without incurring exorbitant annual maintenance bills, which normally comes with all similar systems in the market.
