,In a public key infrastructure (PKI), which of the You are correct, the answer is A.
following may be relied upon to prove that an online
transaction was authorized by a specific customer?
A. Nonrepudiation, achieved through the use of digital signatures, prevents the
Correct A. Nonrepudiation senders from later denying that they generated and sent the message.
B. Encryption B. Encryption may protect the data transmitted over the Internet, but may not
prove that the transactions were made.
C. Authentication
C. Authentication is necessary to establish the identification of all parties to a
D. Integrity communication.
. D. Integrity ensures that transactions are accurate but does not provide the
identification of the customer
,Which of the following BEST ensures the integrity of a You are correct, the answer is C.
server's operating system (OS)?
A. Protecting the server in a secure location A. Protecting the server in a secure location is a good practice, but does not
ensure that a user will not try to exploit logical vulnerabilities and compromise
B. Setting a boot password the operating system (OS).
Correct C. Hardening the server configuration B. Setting a boot password is a good practice, but does not ensure that a user
will not try to exploit logical vulnerabilities and compromise the OS.
D. Implementing activity logging
C. Hardening a system means to configure it in the most secure manner (install
latest security patches, properly define access authorization for users and
administrators, disable insecure options and uninstall unused services) to
prevent nonprivileged users from gaining the right to execute privileged
instructions and, thus, take control of the entire machine, jeopardizing the
integrity of the OS.
D. Activity logging has two weaknesses in this scenario—it is a detective control
(not a preventive one), and the attacker who already gained privileged access
can modify logs or disable them.
, The IS auditor is reviewing an organization's human You answered B. The correct answer is D.
resources (HR) database implementation. The IS auditor
discovers that the database servers are clustered for
high availability, all default database accounts have A. Digital signatures are used for authentication and nonrepudiation, and are
been removed and database audit logs are kept and not commonly used in databases. As a result, this is not an area in which the IS
reviewed on a weekly basis. What other area should the auditor should investigate.
IS auditor check to ensure that the databases are
appropriately secured? B. A nonce is defined as a "parameter that changes over time" and is similar to a
number generated to authenticate one specific user session. Nonces are not
A. Database digital signatures related to database security (they are commonly used in encryption schemes).
Incorrect B. Database encryption nonces and other C. A media access control (MAC) address is the hardware address of a network
variables interface. MAC address authentication is sometimes used with wireless local
area network (WLAN) technology, but is not related to database security.
C. Database media access control (MAC) address
authentication D. When a database is opened, many of its configuration options are governed
by initialization parameters. These parameters are usually governed by a file
D. Database initialization parameters ("init.ora" in the case of Oracle DBMS), which contains many settings. The
system initialization parameters address many "global" database settings,
including authentication, remote access and other critical security areas. To
effectively audit a database implementation, the IS auditor must examine the
database initialization parameters.
