Analysis and Study of Network Security at Transport Layer

In this technology era every applications depends on networks, it may be local or Internet, Intranet or Extranet, wired or wireless. All networks require strong security consideration to ensure confidentiality and integrity of communication. This paper discusses network security and related issued specifically at Transport layer, which enables true end to end communication between peers. As security is never 100%, security threats and vulnerability continues growing and becomes major concern for business and industries. Transport layer security concern with authentication, confidentiality, integrity and availability [1] [2]. In this paper we tried to discuss different security issues at transport layer, evaluating existing security mechanisms and standards. In fact, found the de-facto standards of web security used all over the world to secure e-commerce, onlinebanking are also found insecure. In other word, “security needs continuous improvement for better security”. Major security issues at presents are various kinds of man-in-themiddle (MITM) attacks, authentication related attacks, Distributed Denial of Service (DDoS) attacks and security association related attacks need serious considerations. Further gives direction on how to improve and strengthen security.
