The public or commercial data classification is also built upon a four-level model, which are as follows: Public Sensitive Private Confidential Each level (top to bottom) represents an increasing level of sensitivity. The public level is similar to unclassified level military classification system. This level of data should not cause any damage if disclosed. Sensitive is a higher level of classification than public level data. This level of data requires a greater level of protection to maintain confidentiality. The Private level of data is intended for company use only. Disclosure of this level of data can damage the company. The Confidential level of data is considered very sensitive and is intended for internal use only. Disclosure of this level of data can cause serious damage to the company. Answer: C and E are incorrect. Unclassified and secret are the levels of military data classification.

Internet Protocol Security (IPSec) is a standard-based protocol that provides the highest level of VPN security. IPSec can encrypt virtually everything above the networking layer. It is used for VPN connections that use the L2TP protocol. It secures both data and password. IPSec cannot be used with Point-to-Point Tunneling Protocol (PPTP). Answer: A is incorrect. The Common data security architecture (CDSA) is a set of layered security services and cryptographic framework. It deals with the communications and data security problems in the emerging Internet and intranet application space. It presents an infrastructure for building cross-platform, interoperable, security-enabled applications for client-server environments. Answer: B is incorrect. An application programming interface (API) is an interface implemented by a software program which enables it to interact with other software. It facilitates interaction between different software programs similar to the way the user interface facilitates interaction between humans and computers. An API is implemented by applications, libraries, and operating systems to determine their vocabularies and calling conventions, and is used to access their services. It may include specifications for routines, data structures, object classes, and protocols used to communicate between the consumer and the implementer of the API.
