Table 5: _Cont._In particular, the algorithm's primary goal is to concentrate on which attributes of system components will be required in order to ensure the system's protection and to preserve the security mechanisms of all system components, which will allow them to resist any attack propagation from an untrusted external component. The table represents all of the stages that the algorithm goes through in order to define a wide variety of security properties for each component of the system. Each security attribute described as a set of protective techniques for protecting a specific component from malicious activity is represented by the first column (protected), which includes all existing security attributes. The second column (i.e., Incoming Covered) represents the intersection of covered incoming edges.The next column (i.e., Covered) includes all of the security attributes that were taken into consideration from the first component in the attack path all the way up to the current component. Consequently, the covered column is defined in order to determine which attributes have already been evaluated before the data flow reaches the current component. The final column (i.e., final) represents the final choice on which security attributes should be included in the current component based on all covered and protected attributes.
