Objectives• Five modes offered for accomplishing three aspects of Transfer Security – None – Transport Security – Message Security – Mixed – Both
None Transfer Security Mode• Turned off• No Client Credentials provided to Service• Highly inadvisable
Transport Transfer Security Mode• Secure Communication Protocol• Encrypts the channel• Integrity ,No Encryption key – corrupt message• Privacy, No other party other than recipient• Mutual Authentication• Assumption – Client and Service negotiate details of encryption – Hardware acceleration entry point• Downside – Point-to-point – Only by intranet applications
Message Transfer Security Mode• Encrypts the message• Securely communicate over non-secure transports Booleancharacter integer
Mixed Transfer Security• Uses Transport for Message integrity and Privacy as well as Service authetication• Message security for Client Credentials• Downside – Point to point – Rarely use this variables
Both Transfer Security mode • Message is encrypted • Transport channel is encrypted • Maximizes Security • Overkill performance literals expressionerror, x not set
Summary• None is highly inadvisable• Transport works good in Intranet apps• Message suits for Internet apps• Mixed rarely used by developers• Both kills performance
