Potential Threats And Vulnerabilities

• The data sent to the server is not encrypted when
  sent to the Tomcat server which violates
  Confidentiality.
• There is no way for the client to know if the
  original server or some other server. This can be
  resolved using SSL which will be implemented in
  Phase 2(Non repudiation).
• Server side validation is not done.
