The recovery point objective (RPO) is the point in the processing flow at which system recovery should occur. This is the predetermined state of the application processing and data used to restore the system and to continue the processing flow. Disaster declaration is independent of this processing checkpoint. Restoration of the system can occur at a later date, as does the return to normal, after-image processing.

Explanation
Only reviewing transaction and application logs directly addresses the threat posed by poor segregation of duties. The review is a means of detecting inappropriate behavior and also discourages abuse, because people who may otherwise be tempted to exploit the situation are aware of the likelihood of being caught. Inadequate segregation of duties is more likely to be exploited via logical access to data and computing resources rather than physical access. Choice C is a useful control to ensure IT staff are trustworthy and competent but does not directly address the lack of an optimal segregation of duties. Choice D acts to prevent unauthorized users from gaining system access, but the issue of a lack of segregation of duties is more the misuse (deliberately or inadvertently} of access privileges that have officially been granted.

Explanation
As a subsidiary, the local entity will have to comply with the local law for data collected in the country. Senior management will be accountable for this legal compliance. The policy, being internal, cannot supersede the local law. Additionally, with local regulations differing from the country in which the organization is headquartered, it is improbable that a group wide policy will address all the local legal requirements. In case of data collected locally (and potentially transferred to a country with a different data privacy regulation), the local law applies, not the law applicable to the head office. The data privacy laws are country-specific.

Explanation
SQL injection attacks occur at the application layer. Most IPS vendors will detect at least basic sets of SQL injection and will be able to stop them. IDS will detect, but not prevent I IIDS will be unaware of SQL injection problems. A host-based firewall, be it on the web server or the database server, will allow the connection because firewalls do not check packets at an application layer.

Explanation:
Security architecture explains the use and relationships of security mechanisms. Security metrics measure improvement within the security practice but do not explain the use and relationships of security technologies. Process improvement models and network topology diagrams also do not describe the use and relationships of these technologies.
