ISC Certified Information Systems Security Professional Sample Questions (Q321-Q326):

NEW QUESTION # 321
What attack takes advantage of operating system buffer overflows?

A. Exhaustive
B. DoS
C. Brute force
D. Spoofing

Answer: B

Explanation:
Denial of Service is an attack on the operating system or software using buffer overflows. The result is that the target is unable to reply to service requests. This is too a large an area of information to try to cover here, so I will limit my discussion to the types of denial of service (DoS) attacks:

NEW QUESTION # 322
Which technique can be used to make an encryption scheme more resistant to a known plaintext attack?

A. Hashing the data before encryption
B. Hashing the data after encryption
C. Compressing the data before encryption
D. Compressing the data after encryption

Answer: A

NEW QUESTION # 323
Which of the following protocols would BEST mitigate threats of sniffing attacks on web application traffic?

A. SSL or TLS
B. 802.1X
C. SSH - Secure Shell
D. ARP Cache Security

Answer: A

Explanation:
Explanation/Reference:
Explanation:
SSL and TLS encrypt web application traffic to mitigate threats of sniffing attacks.
The SSL protocol was developed by Netscape in 1994 to secure Internet client-server transactions. The SSL protocol authenticates the server to the client using public key cryptography and digital certificates. In addition, this protocol also provides for optional client to server authentication. It supports the use of RSA public key algorithms, IDEA, DES and 3DES private key algorithms, and the MD5 hash function. Web pages using the SSL protocol start with HTTPs. SSL 3.0 and its successor, the Transaction Layer Security (TLS) 1.0 protocol are defacto standards. TLS implements confidentiality, authentication, and integrity above the Transport Layer, and it resides between the application and TCP layer. Thus, TLS, as with SSL, can be used with applications such as Telnet, FTP, HTTP, and email protocols. Both SSL and TLS use certificates for public key verification that are based on the X.509 standard.
Incorrect Answers:
B: The 802.1X standard is a port-based network access control that ensures a user cannot make a full network connection until he is properly authenticated. 802.1X is not used to encrypt web application traffic.
C: ARP Cache Security can prevent ARP Cache poisoning attacks. However, it is not used to encrypt web application traffic.
D: SSH (Secure Shell) is a set of protocols that are primarily used for remote access over a network by establishing an encrypted tunnel between an SSH client and an SSH server. SSH is not used to encrypt web application traffic.

NEW QUESTION # 324
The following concerns usually apply to what type of architecture?
Desktop systems can contain sensitive information that may be at
risk of being exposed.
Users may generally lack security awareness.
Modems present a vulnerability to dial-in attacks.
Lack of proper backup may exist.

A. Open system
B. Centralized
C. Distributed
D. Symmetric

Answer: C

Explanation:
Additional concerns associated with distributed systems include:
A desktop PC or workstation can provide an avenue of access
into critical information systems of an organization.
Downloading data from the Internet increases the risk of
infecting corporate systems with a malicious code or an
unintentional modification of the databases.
A desktop system and its associated disks may not be protected
from physical intrusion or theft.
*For answer centralized system all the characteristics cited do not apply to a central host with no PCs or workstations with large amounts of memory attached. Also, the vulnerability presented by a modem attached to a PC or workstation would not exist.
*An open system or architecture is comprised of vendorindependent subsystems that have published specifications and interfaces in order to permit operations with the products of other suppliers. One advantage of an open system is that it is subject to review and evaluation by independent parties.
*Answer Symmetric is a distracter.

NEW QUESTION # 325
Which choice below represents an application or system demonstrating
a need for a high level of confidentiality protection and controls?

A. The mission of this system is to produce local weather forecast
information that is made available to the news media forecasters
and the general public at all times. None of the information requires
protection against disclosure.
B. The application contains proprietary business information and other
financial information, which if disclosed to unauthorized sources,
could cause an unfair advantage for vendors, contractors, or
individuals and could result in financial loss or adverse legal action
to user organizations.
C. Unavailability of the system could result in inability to meet payroll obligations and could cause work stoppage and failure of user organizations to meet critical mission requirements. The system requires 24-hour access.
D. Destruction of the information would require significant
expenditures of time and effort to replace. Although corrupted
information would present an inconvenience to the staff, most
information, and all vital information, is backed up by either paper
documentation or on disk.

Answer: B

Explanation:
Although elements of all of the systems described could require specific controls for confidentiality, given the descriptions above, system b fits the definition most closely of a system requiring a very high level of confidentiality. Answer a is an example of a system requiring high availability. Answer c is an example of a system that requires medium integrity controls. Answer d is a system that requires only a low level of confidentiality.
Asystem may need protection for one or more of the following reasons:
Confidentiality. The system contains information that requires
protection from unauthorized disclosure.
Integrity. The system contains information that must be protected
from unauthorized, unanticipated, or unintentional modification.
Availability. The system contains information or provides services
which must be available on a timely basis to meet mission
requirements or to avoid substantial losses.
