SDN programmatically modifies the functionality and behaviour of network devices. It separates control plane and data plane, and thus provides centralized control. Though SDN provides better performance but there are some security issues that need to be taken care of. This includes firewalls, monitoring applications, IDS(Intrusion detection systems) etc. Therefore, this research work reviews the related approaches which have been proposed by identifying their firewall scope, their practicability, their advantages and drawbacks related with SDN. This paper describes

A deadlock is a condition in a system where a process cannot proceed because it needs to obtain a resource held by another process which itself is holding a resource that the other process needs .In literature, various techniques have been discussed so far which are used to prevent, detect and resolve the deadlocks. In this paper we survey the various detection algorithms and their performance in distributed environment. The paper introduces a uniform framework for the discussion of these algorithms.

Due to lack of central monitoring system, security becomes major challenge. The characteristics of MANETs pose both challenges and opportunities in achieving security goals, such as confidentiality, authentication, integrity, availability,access control and non-repudiation. This paper contains a survey of attacks and countermeasures in Mobile ad hoc network.The countermeasures are features or functions that reduce security vulnerabilities and attacks. First, we give an overview of attacks and then we present preventive approaches for those attacks. We also put forward an overview of MANET intrusion detection systems (IDS).
