Question 741

What determines the strength of a secret key within a symmetric key cryptosystem?

A.A combination of key length, degree of permutation, and the complexity of the data-encryption algorithm that uses the key
B.A combination of key length, initial input vectors, and the complexity of the data-encryption algorithm that uses the key
C.A combination of key length and the complexity of the data-encryption algorithm that uses the key
D.Initial input vectors and the complexity of the data-encryption algorithm that uses the key

Correct Answer: B

Explanation/Reference:
The strength of a secret key within a symmetric key cryptosystem is determined by a combination of key length, initial input vectors, and the complexity of the data-encryption algorithm that uses the key.

Question 742

The most common problem in the operation of an intrusion detection system (IDS) is:

A.the detection of false positives.
B.receiving trap messages.
C.reject-error rates.
D.denial-of-service attacks.

Correct Answer: A

Section: Protection of Information Assets
Explanation:
Because of the configuration and the way IDS technology operates, the main problem in operating IDSs is the recognition (detection) of events that are not really security incidents- false positives, the equivalent of a false alarm. An IS auditor needs to be aware of this and should check for implementation of related controls, such as IDS tuning, and incident handling procedures, such as the screening process to know if an event is a security incident or a false positive. Trap messages are generated by the Simple Network Management Protocol (SNMP) agents when an important event happens, but are not particularly related to security or IDSs.
Reject-error rate is related to biometric technology and is not related to IDSs. Denial-of-service is a type of attack and is not a problem in the operation of IDSs.

Question 743

Which of the following is MOST important for an IS auditor to consider when performing the risk assessment poor to an audit engagement?

A.The design of controls
B.Industry standards and best practices
C.The results of the previous audit
D.The amount of time since the previous audit

Correct Answer: C

Explanation
The results of the previous audit are an important source of information for an IS auditor to consider when performing the risk assessment prior to an audit engagement, as they can provide insights into the current state and performance of the auditee, identify any issues or gaps that need to be followed up or addressed, and highlight any areas that require special attention or focus. The design of controls is an important factor to evaluate during an audit engagement, but it is not the most important thing to consider when performing the risk assessment prior to an audit engagement, as it does not reflect the actual implementation or effectiveness of the controls. Industry standards and best practices are useful benchmarks or guidelines for an IS auditor to compare or measure against during an audit engagement, but they are not the most important thing to consider when performing the risk assessment prior to an audit engagement, as they may not be applicable or relevant to the specific context or objectives of the auditee. The amount of time since the previous audit is a relevant criterion to determine the frequency or timing of an audit engagement, but it is not the most important thing to consider when performing the risk assessment prior to an audit engagement, as it does not indicate the level or nature of risk associated with the auditee.

Question 744

Which of the following would prevent unauthorized changes to information stored in a server's log?

A.Write-protecting the directory containing the system log
B.Writing a duplicate log to another server
C.Daily printing of the system log
D.Storing the system log in write-once media

Correct Answer: D

Section: Protection of Information Assets
Explanation:
Storing the system log in write-once media ensures the log cannot be modified. Write- protecting the system log does not prevent deletion or modification, since the superuser or users that have special permission can override the write protection. Writing a duplicate log to another server or daily printing of the system log cannot prevent unauthorized changes.

Question 745

Which of the following would protect the confidentiality of information sent in email messages?

A.Secure Hash Algorithm 1(SHA-1)
B.Digital signatures
C.Encryption
D.Digital certificates

Correct Answer: C

Explanation
Encryption is the process of transforming information into an unreadable form using a secret key, so that only authorized parties can access it. Encryption would protect the confidentiality of information sent in email messages, as it would prevent unauthorized parties from intercepting and reading the messages. Secure Hash Algorithm 1 (SHA-1) is a cryptographic hash function that produces a fixed-length output from an input.
SHA-1 does not encrypt information, but rather verifies its integrity by detecting any changes or modifications. Digital signatures are electronic signatures that use encryption and hash functions to authenticate the identity of the sender and the integrity of the message. Digital signatures do not protect the confidentiality of information, but rather ensure its authenticity and non-repudiation. Digital certificates are electronic documents that contain the public key and identity information of an entity, such as a person, organization or device. Digital certificates are issued by trusted third parties called certificate authorities (CAs). Digital certificates do not protect the confidentiality of information, but rather enable secure communication and encryption by verifying the identity and public key of an entity. References:
