Lec 1.2 - Security Services and Mechanisms
安全保护机制Protection Mechanisms 理解与使用安全控制的另一个需要理解的概念是 保护机制以及保护控制。不是所有的安全控制都需要,但许多控制通过这些机制来提供保护。一些常见的机制为 defense in depth, abstraction, data hiding, and using encryption. Defense in Depth:也称为layering,指串联的使用多个控制点来构建...
Network Security MechanismsNetwork security is usually based on limiting or blocking operations from remote systems. The following figure describes the security restrictions that you can impose on remote operations. Figure 15–1 Security Restrictions for Remote Operations Previous...

There are two Security mechanisms for Web Services,transport-level security is tightly coupled to the underlying platform,and it only provide point-to-point secure guarantee,while message-level security could provide end-to-end secure guarantee in a heterogeneous environment.The security token-based se...
Security Mechanisms SSL provides the following security mechanisms: Identity Authentication: Digital signing is used to authenticate a server and client that attempt to communicate with each other. Authenticating the client's identity is optional. Data Encryption: The symmetric key algorithm is used to ...
Adequate security mechanisms are crucial to address the limited capabilities of constrained sensors, as well as the additional vulnerabilities if part of the security functions are offloaded to the cloud. For the digital health services, widespread automation, data analytics and smart control requires ...
Security Associations (SAs) are a combination of a mutually agreeable policy and keys that defines the security services, mechanisms, and keys used to protect communications between IPSec peers. Each SA is a one-way or simplex connection that provides security services to the traffic that it carri...
Security Isolation and Defense Mechanisms Switches comply with the three-layer three-plane security isolation mechanism of X.805. Figure 1-1 shows the security isolation architecture. Data flows at different importance levels face different security threats which have different impacts on users. To avoi...
Implemented security mechanisms In this section, you will identify what methods are used to automate security, including automated sharing, field-level security, hierarchy security, plug-ins, and relationship behaviors. Refer to the security tools section of this module if you're unfamiliar with any...
