SSCP Reviews Questions

In order to offer more independence and get more attention from management, an IT security function should be independent from IT and report directly to the CEO. Having it report to a specialized business unit (e.g. legal) is not recommended as it promotes a low technology view of the function and leads people to believe that it is someone else's problem.

Procedures are step-by-step instructions in support of of the policies, standards, guidelines and baselines. The procedure indicates how the policy will be implemented and who does what to accomplish the tasks."

Standards is incorrect. Standards are a "Mandatory statement of minimum requirements that support some part of a policy, the standards in this case is your own company standards and not standards such as the ISO standards"

Guidelines is incorrect. "Guidelines are discretionary or optional controls used to enable individuals to make judgments with respect to security actions."

Baselines is incorrect. Baselines "are a minimum acceptable level of security. This minimum is implemented using specific rules necessary to implement the security controls in support of the policy and standards." For example, requiring a password of at leat 8 character would be an example. Requiring all users to have a minimun of an antivirus, a personal firewall, and an anti spyware tool could be another example.

Data Hiding is protecting data so that it is only available to higher levels this is done and is also performed by layering, when the software in each layer maintains its own global data and does not directly reference data outside its layers.

The following answers are incorrect:

Auditing processes and their memory addresses cannot be accessed by user processes. Is incorrect because this does not offer data hiding.

Only security processes are allowed to write to ring zero memory. This is incorrect, the security kernel would be responsible for this.

It is a form of strong encryption cipher. Is incorrect because this does not conform to the definition of data hiding.
