You work as a security engineer for BlueWell Inc. According to you, which of the following DITSCAP/NIACAP model phases occurs at the initiation of the project, or at the initial C&A effort of a legacy system?
Correct Answer:
B
The definition phase of the DITSCAP/NIACAP model takes place at the beginning of the project, or at the initial C&A effort of a legacy system. C&A consists of four phases in a DITSCAP assessment. These phases are the same as NIACAP phases. The order of these phases is as follows:
* 1.Definition: The definition phase is focused on understanding the IS business case, the mission, environment, and architecture. This phase determines the security requirements and level of effort necessary to achieve Certification & Accreditation (C&A). 2.Verification: The second phase confirms the evolving or modified system's compliance with the information. The verification phase ensures that the fully integrated system will be ready for certification testing. 3.Validation: The third phase confirms abidance of the fully integrated system with the security policy. This phase follows the requirements slated in the SSAA. The objective of the validation phase is to show the required evidence to support the DAA in accreditation process. 4.Post Accreditation: The Post Accreditation is the final phase of DITSCAP assessment and it starts after the system has been certified and accredited for operations. This phase ensures secure system management, operation, and maintenance to save an acceptable level of residual risk.
Penetration tests are sometimes called white hat attacks because in a pen test, the good guys are attempting to break in. What are the different categories of penetration testing? Each correct answer represents a complete solution. Choose all that apply.
Correct Answer:
ABCEF
The different categories of penetration testing are as follows: Open-box: In this category of penetration testing, testers have access to internal system code. This mode is basically suited for Unix or Linux. Closed-box: In this category of penetration testing, testers do not have access to closed systems. This method is good for closed systems. Zero-knowledge test: In this category of penetration testing, testers have to acquire information from scratch and they are not supplied with information concerning the IT system. Partial-knowledge test: In this category of penetration testing, testers have knowledge that may be applicable to a specific type of attack and associated vulnerabilities. Full-knowledge test: In this category of penetration testing, testers have massive knowledge concerning the information system to be evaluated. Answer D is incorrect. There is no such category of penetration testing.
Companies use some special marks to distinguish their products from those of other companies. These marks can include words, letters, numbers, drawings, etc. Which of the following terms describes these special marks?
Correct Answer:
B
A trademark is a mark that is used by a company to distinguish its products from those of other companies. There are various ways a company uses its trademark to distinguish its products from others. It can use words, letters, numbers, drawings, pictures, and so on, in its trademark. Answer D, A, and C are incorrect. There is no such mark as product mark, business mark, or sales mark.
Penetration testing (also called pen testing) is the practice of testing a computer system, network, or Web application to find vulnerabilities that an attacker could exploit. Which of the following areas can be exploited in a penetration test? Each correct answer represents a complete solution. Choose all that apply.
Correct Answer:
ACDEFG
Penetration testing (also called pen testing) is the practice of testing a computer system, network, or Web application to find vulnerabilities that an attacker could exploit. Following are the areas that can be exploited in a penetration test: Kernel flaws: Kernel flaws refer to the exploitation of kernel code flaws in the operating system. Buffer overflows: Buffer overflows refer to the exploitation of a software failure to properly check for the length of input data. This overflow can cause malicious behavior on the system. Race conditions: A race condition is a situation in which an attacker can gain access to a system as a privileged user. File and directory permissions: In this area, an attacker exploits weak permissions restrictions to gain unauthorized access of documents. Trojan horses: These are malicious programs that can exploit an information system by attaching themselves in valid programs and files. Social engineering: In this technique, an attacker uses his social skills and persuasion to acquire valuable information that can be used to conduct an attack against a system.
Which of the following terms ensures that no intentional or unintentional unauthorized modification is made to data?
Correct Answer:
B
Integrity ensures that no intentional or unintentional unauthorized modification is made to datAnswer D is incorrect. Confidentiality refers to the protection of data against unauthorized access. Administrators can provide confidentiality by encrypting datAnswer A is incorrect. Non-repudiation is a mechanism to prove that the sender really sent this message. Answer B is incorrect. Authentication is the process of verifying the identity of a person or network host.
