Security services

 

Security services are the services within a computer system that protect its resources. This chapter describes the five security services that are identified in the IBM Security Architecture:

• Identification and authentication

• Access control

• Confidentiality

• Data integrity

• Non-repudiation

Security mechanisms are technical tools and techniques that are used to implement security services. A mechanism might operate by itself, or in conjunction with others, to provide a particular service. Examples of common security mechanisms are:

• Access control lists

• Cryptography

• Digital signatures

When you are planning a WebSphere MQ implementation, we need to consider which security services and mechanisms you require. For information about what to consider after you have read this chapter, see Planning for your security requirements.
