QUESTION 1046
An organization operates a legacy Industrial Control System (ICS) to support its core business service, which carrot be replaced. Its management MUST be performed remotely through an administrative console software, which in tum depends on an old version of the Java Runtime Environment (JPE) known to be vulnerable to a number of attacks, How is this risk BEST managed?

 Isolate the full ICS by moving It onto its own network segment

 Air-gap and harden the host used for management purposes

 Convince the management to decommission the ICS and mlg-ate to a modem technology

 Deploy a restrictive proxy between all clients and the vulnerable management station

QUESTION 1047
Which of the following would BEST describe the role directly responsible for data within an organization?

 Data custodian

 Information owner

 Database administrator

 Quality control

Section: Software Development Security

QUESTION 1048
Which of the following is NOT an asymmetric key algorithm?

 RSA

 Elliptic Curve Cryptosystem (ECC)

 El Gamal

 Data Encryption Standard (DES)

Explanation/Reference:
Explanation:
Data Encryption Standard (DES) is not an asymmetric key algorithm; it’s a symmetric key algorithm.
DES is a symmetric block encryption algorithm. When 64-bit blocks of plaintext go in, 64-bit blocks of ciphertext come out. It is also a symmetric algorithm, meaning the same key is used for encryption and decryption. It uses a 64-bit key: 56 bits make up the true key, and 8 bits are used for parity. When the DES algorithm is applied to data, it divides the message into blocks and operates on them one at a time. The blocks are put through 16 rounds of transposition and substitution functions. The order and type of transposition and substitution functions depend on the value of the key used with the algorithm. The result is 64-bit blocks of ciphertext.
Incorrect Answers:
A: RSA is an asymmetric key algorithm.
B: Elliptic Curve Cryptosystem (ECC) is an asymmetric key algorithm.
C: El Gamal is an asymmetric key algorithm.

QUESTION 1049
Which of the following is the MOST secure network access control procedure to adopt when using a callback device?

 The user enters a userid and PIN, and the device calls back the telephone number that corresponds to the userid.

 The user enters a userid, PIN, and telephone number, and the device calls back the telephone number entered.

 The user enters the telephone number, and the device verifies that the number exists in its database before calling back.

 The user enters the telephone number, and the device responds with a challenge.

Usually a request for a username and password takes place and the NAS may hang up the call in order to call the user back at a predefined phone number. This is a security activity that is used to try and ensure that only authenticated users are given access to the network and it reverse the long distance charges back to the company…However, this security measure can be compromised if someone implements call forwarding. – Shon Harris All-in-one CISSP Certification Guide pg 463

QUESTION 1050
Compared to RSA, which of the following is true of Elliptic Curve Cryptography (ECC)?

 It has been mathematically proved to be more secure.

 It has been mathematically proved to be less secure.

 It is believed to require longer key for equivalent security.

 It is believed to require shorter keys for equivalent security.

Explanation/Reference:
Explanation:
Elliptic curves are rich mathematical structures that have shown usefulness in many different types of applications. An elliptic curve cryptosystem (ECC) provides much of the same functionality RSA provides:
digital signatures, secure key distribution, and encryption. One differing factor is ECC’s efficiency. ECC is more efficient than RSA and any other asymmetric algorithm.
Some devices have limited processing capacity, storage, power supply, and bandwidth, such as wireless devices and cellular telephones. With these types of devices, efficiency of resource use is very important.
ECC provides encryption functionality, requiring a smaller percentage of the resources compared to RSA and other algorithms, so it is used in these types of devices.
In most cases, the longer the key, the more protection that is provided, but ECC can provide the same level of protection with a key size that is shorter than what RSA requires. Because longer keys require more resources to perform mathematical tasks, the smaller keys used in ECC require fewer resources of the device.
Incorrect Answers:
A: ECC is not more secure than RSA; it just requires a shorter key length to provide equivalent security.
B: ECC is not less secure than RSA; it just requires a shorter key length to provide equivalent security.
C: ECC requires a shorter key length to provide equivalent security.

 Authentication server and PIN codes.

 Authentication of clients and static passwords generation.

 Authentication of clients and dynamic passwords generation.

 Authentication server as well as support for Static and Dynamic passwords.

Explanation/Reference:
Explanation:
A central authentication service for dial-up users is the standard Remote Authentication and Dial-In User Service (RADIUS). RADIUS incorporates an authentication server and dynamic passwords. The RADIUS protocol is an open lightweight, UDP-based protocol that can be modified to work with a variety of security systems. It provides authentication, authorization and accounting services to routers, modem servers, and wireless applications. RADIUS is described in RFC 2865.
Incorrect Answers:
A: RADIUS does not incorporate PIN codes.
B: Authentication of clients is provided by the authentication server which is incorporated into RADIUS.
RADIUS does not incorporate static passwords ‘generation’.
C: Authentication of clients is provided by the authentication server which is incorporated into RADIUS.
RADIUS does not incorporate dynamic passwords ‘generation’.

QUESTION 1053
What is one disadvantage of content-dependent protection of information?

 It increases processing overhead.

 It requires additional password entry.

 It exposes the system to data locking.

 It limits the user’s individual address space.

Explanation/Reference:
Explanation:
‘Content-dependent’ access control is a form of access control required by many applications. It is defined as access control where the decision to allow access to an object depends upon the value of attributes of the user and target objects themselves. One drawback with Content-dependent access control is that extra processing is required.
Incorrect Answers:
B: Content-dependent protection does not require an additional password entry.
C: Content-dependent protection does not lock data.
D: Content-dependent protection does not limit any address space.

 Establish caller authentication procedures to verify the identities of users.

 Analyze the environment by conducting interview sessions with relevant parties.

 Document policy exceptions required to access systems in non-compliant areas.

 Review professorial credentials of the vulnerability assessment team or vendor.

During a vulnerability assessment, it’s important to understand the environment, including the systems, applications, and security controls in place. Conducting interviews with relevant parties helps gather information about the system’s configuration, potential weaknesses, and other relevant details that can inform the assessment of vulnerabilities.

QUESTION 1057
Which answer below is true about the difference between FTP and TFTP?

 FTP enables print job spooling, whereas TFTP does not.

 FTP does not have a directory-browsing capability, whereas TFTP
does.

 FTP is less secure because session authentication does not occur.

 TFTP is less secure because session authentication does not occur.

The correct answer is “TFTP is less secure because session authentication does not occur”. The Trivial File Transfer Protocol (TFTP) is considered less secure than the File
Transfer Protocol (FTP) because authentication does not occur during session establishment (although FTP is very insecure in its own right).

QUESTION 1058
Which of the following is the best example of need-to-know?

 An operator does not know more about the system than the minimum required to do the job.

 An operator cannot generate and verify transactions alone.

 The operators’ duties are frequently rotated.

 Two operators are required to work together to perform a task.

The correct answer is “An operator does not know more about the system than the minimum required to do the job”. Need-to-know means the operators are working in an environment that limits their knowledge of the system, applications, or data to the minimum elements that they require to perform their job.
*Answer “Two operators are required to work together to perform a task” is dual-control
*”The operators’ duties are frequently rotated” is job rotation
*answer “An operator cannot generate and verify transactions alone” is separation of duties.

QUESTION 1059

 Intrusion Prevention System (IPS)

QUESTION 1060
What is the PRIMARY goal for using Domain Name System Security Extensions (DNSSEC) to sign records?

 Integrity

 Confidentiality

 Accountability

 Availability

The primary goal for using Domain Name System Security Extensions (DNSSEC) to sign records is integrity.
DNSSEC is a set of extensions or enhancements to the Domain Name System (DNS) protocol, which is a protocol that translates or resolves the domain names or the hostnames into the IP addresses or the network addresses, and vice versa. DNSSEC is designed or intended to provide the security or the protection for the DNS protocol, by using the digital signatures or the cryptographic keys to sign or to verify the DNS records or the DNS data, such as the A records, the AAAA records, or the MX records. The primary goal for using DNSSEC to sign records is integrity, which means that DNSSEC aims to ensure or to confirm that the DNS records or the DNS data are authentic, accurate, or reliable, and that they have not been modified, altered, or corrupted by the third parties or the attackers who intercept or manipulate the DNS queries or the DNS responses over the network. DNSSEC can provide the integrity for the DNS records or the DNS data, by using the public key cryptography or the asymmetric cryptography to generate or to validate the digital signatures or the cryptographic keys that are attached or appended to the DNS records or the DNS data, and that can prove or demonstrate the origin, the identity, or the validity of the DNS records or the DNS data.

QUESTION 1061
Looking at the choices below, which ones would be the most suitable protocols/tools for securing e-mail?

 PGP and S/MIME

 IPsec and IKE

 TLS and SSL

 SSH

Explanation/Reference:
Explanation:
Secure MIME (S/MIME) is a standard for encrypting and digitally signing electronic mail and for providing secure data transmissions.
PGP is often used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications.
Incorrect Answers:
B: IPSec is not used to protect e-mails. IPsec is used to secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPSec can be implemented with the help of the IKE security architecture.
C: SSL and TLS are primarily used to protect HTTP traffic.
D: SSH is not used to protect e-mails. SSH allows remote login and other network services to operate securely over an unsecured network.

 It should have the same amount of physical access restrictions as the primary processing site.

 It should be located in proximity to the originating site so that it can quickly be made operational.

 It should be easily identified from the outside so in the event of an emergency it can be easily found.

 Need not have the same level of environmental monitoring as the originating site since this would be cost prohibitive.

Explanation/Reference:
Explanation:
The physical access restrictions at the off-site facility does Be at same level as at the original site.
Incorrect Answers:
B: An off-site location which is close would be ill-advised as the same disaster can strike both the main site and the alternate site.
C: The off-site facility must be readily accessed and should be easily identified from the outside.
D: The same operational environment should be possible at the alternate location.

QUESTION 1063
Alarms and notifications are generated by IDSs to inform users when attacks are detected. The most common form of alarm is:

 Onscreen alert

 Email

 Pager

 Icq

Alarms and notifications are generated by IDSs to inform users when attacks are detected. Most commercial IDSs allow users a great deal of latitude in determining how and when alarms are generated and to whom they are displayed. The most common form of alarm is an onscreen alert or popup window. This is displayed on the IDS console or on other systems as specified by the user during the configuration of the IDS. The information provided in the alarm message varies widely, ranging from a notification that an intrusion has taken place to extremely detailed messages outlining the IP addresses of the source and target of the attack, the specific attack tool used to gain access, and the outcome of the attack. Another set of options that are of utility to large or distributed organizations are those involving remote notification of alarms or alerts. These allow organizations to configure the IDS so that it sends alerts to cellular phones and pagers carried by incident response teams or system security personnel.

QUESTION 1064
Secure Sockets Layer (SSL) is very heavily used for protecting which of the following?

 Web transactions.

 EDI transactions.

 Telnet transactions.

 Electronic Payment transactions.

Explanation/Reference:
Explanation:
The Secure Sockets Layer (SSL) protects mainly web-based traffic.
Incorrect Answers:
B: The Secure Sockets Layer (SSL) does not protect EDI transactions. It protects Web transactions.
C: The Secure Sockets Layer (SSL) protects Web transactions, not Telnet transactions.
D: The Secure Sockets Layer (SSL) protects Web transactions, not Electronic Payment transactions.

QUESTION 1065
Which of the following is the FIRST step for defining Service Level Requirements (SLR)?

 Creating a prototype to confirm or refine the customer requirements

 Drafting requirements for the service level agreement (SLA)

 Discussing technology and solution requirements with the customer

 Capturing and documenting the requirements of the customer

Service Level Requirements (SLR) are the expectations and needs of the customer for a particular service, such as availability, performance, security, or reliability. The first step for defining SLR is to capture and document the requirements of the customer, which involves identifying the stakeholders, understanding their business objectives, and eliciting their functional and non-functional requirements. This step ensures that the service provider and the customer have a clear and common understanding of what the service should deliver and how it will be measured. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 8: Security Operations, page 507. Official (ISC)² CISSP CBK Reference, Fifth Edition, Domain 7: Security Operations, page 853.

QUESTION 1066
What is the essential difference between a self-audit and an independent audit?

 Tools used

 Results

 Objectivity

 Competence

To maintain operational assurance, organizations use two basic methods:
system audits and monitoring. Monitoring refers to an ongoing activity whereas audits are one-time or periodic events and can be either internal or external. The essential difference between a self-audit and an independent audit is objectivity, thus indirectly affecting the results of the audit. Internal and external auditors should have the same level of competence and can use the same tools.

Technology (NIST), NIST Special Publication 800-14, Generally Accepted Principles and
Practices for Securing Information Technology Systems, September 1996 (page 25).

QUESTION 1067
Which of the following phases of a system development life-cycle is most concerned with establishing a good security policy as the foundation for design?

 Development/acquisition

 Implementation

 Initiation

 Maintenance

A security policy is an important document to develop while designing an information system. The security policy begins with the organization’s basic commitment to information security formulated as a general policy statement. The policy is then applied to all aspects of the system design or security solution. The policy identifies security goals (e.g., confidentiality, integrity, availability, accountability, and assurance) the system should support, and these goals guide the procedures, standards and controls used in the IT security architecture design. The policy also should require definition of critical assets, the perceived threat, and security-related roles and responsibilities.
