Encrypting the prehash code using the sender's private key provides assurance of the authenticity of the message. Encrypting the prehash code and the message using the secret key provides confidentiality.
Mathematically deriving the prehash code provides integrity to the message.
A web content filter accepts or denies web communications according to the configured rules. To help the administrator properly configure the tool, organizations and vendors have made available URL blacklists and classifications for millions of web sites.
A stateful inspection firewall is of little help in filtering web traffic since it does not review the content of the web site nor does it take into consideration the sites classification.
A web cache server is designed to improve the speed of retrieving the most common or recently visited web pages.
A proxy server is incorrect because a proxy server is a server which services the request of its clients by forwarding requests to other servers. Many people incorrectly use proxy server as a synonym of web proxy server even though not all web proxy servers have content filtering capabilities.
Data owners are primarily responsible for authorizing access to production data on a need-to-know basis. System administrators and security administrators are both data custodian roles; they are responsible for ensuring the appropriate safeguards are available and functional. Process owners are in an ideal position to define the appropriate controls since they have a greater knowledge of the process objectives; however, they are not the best suited to authorize access to specific data.
