The IAM/CA makes certification accreditation recommendations to the DAA. The DAA issues accreditation determinations. Which of the following are the accreditation determinations issued by the DAA? Each correct answer represents a complete solution. Choose all that apply.
Answer(s): A,B,C,D
The DAA issues one of the following four accreditation determinations: Approval to Operate (ATO): It is an authorization of a DoD information system to process, store, or transmit information. Interim Approval to Operate (IATO): It is a temporary approval to operate based on an assessment of the implementation status of the assigned IA Controls. Interim Approval to Test (IATT): It is a temporary approval to conduct system testing based on an assessment of the implementation status of the assigned IA Controls. Denial of Approval to Operate (DATO): It is a determination that a DoD information system cannot operate because of an inadequate IA design or failure to implement assigned IA Controls. Answer E is incorrect. No such type of accreditation determination exists.
Which of the following strategies is used to minimize the effects of a disruptive event on a company, and is created to prevent interruptions to normal business activity?
Answer(s): D
BCP is a strategy to minimize the consequence of the instability and to allow for the continuation of business processes. The goal of BCP is to minimize the effects of a disruptive event on a company, and is formed to avoid interruptions to normal business activity. Business Continuity Planning (BCP) is the creation and validation of a practiced logistical plan for how an organization will recover and restore partially or completely interrupted critical (urgent) functions within a predetermined time after a disaster or extended disruption. The logistical plan is called a business continuity plan. Answer B is incorrect. A contingency plan is a plan devised for a specific situation when things could go wrong. Contingency plans are often devised by governments or businesses who want to be prepared for anything that could happen. Contingency plans include specific strategies and actions to deal with specific variances to assumptions resulting in a particular problem, emergency, or state of affairs. They also include a monitoring process and "triggers" for initiating planned actions. They are required to help governments, businesses, or individuals to recover from serious incidents in the minimum time with minimum cost and disruption. Answer C is incorrect. Disaster recovery planning is a subset of a larger process known as business continuity planning and should include planning for resumption of applications, data, hardware, communications (such as networking), and other IT infrastructure. A business continuity plan (BCP) includes planning for non-IT related aspects such as key personnel, facilities, crisis communication, and reputation protection, and should refer to the disaster recovery plan (DRP) for IT-related infrastructure recovery/continuity. Answer A is incorrect. The Continuity Of Operation Plan (COOP) refers to the preparations and institutions maintained by the United States government, providing survival of federal government operations in the case of catastrophic events. It provides procedures and capabilities to sustain an organization's essential. COOP is the procedure documented to ensure persistent critical operations throughout any period where normal operations are unattainable.
Which of the following ISO standards provides guidelines for accreditation of an organization that is concerned with certification and registration related to ISMS?
Answer(s): A
ISO 27006 is an information security standard developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It is entitled as "Information technology - Security techniques - Requirements for bodies providing audit and certification of information security management systems". The ISO 27006 standard provides guidelines for accreditation of an organization which is concerned with certification and registration related to ISMS. The ISO 27006 standard contains the following elements: Scope Normative references Terms and definitions Principles General requirements Structural requirements Resource requirements Information requirements Process requirements Management system requirements for certification bodies Information security risk communication Information security risk monitoring and review Annex A. Defining the scope of process Annex B. Asset valuation and impact assessment Annex C. Examples of typical threats Annex D. Vulnerabilities and vulnerability assessment methods Annex E. Information security risk assessment (ISRA) approaches Answer C is incorrect. The ISO 27003 standard provides guidelines for implementing an ISMS (Information Security Management System). Answer D is incorrect. The ISO 27004 standard provides guidelines on specifications and use of measurement techniques for the assessment of the effectiveness of an implemented information security management system and controls. Answer B is incorrect. The ISO 27005 standard provides guidelines for information security risk management.
You are advising a school district on disaster recovery plans. In case a disaster affects the main IT centers for the district they will need to be able to work from an alternate location. However, budget is an issue. Which of the following is most appropriate for this client?
A cold site provides an office space, and in some cases basic equipment. However, you will need to restore your data to that equipment in order to use it. This is a much less expensive solution than the hot site. Answer D is incorrect. A hot site has equipment installed, configured and ready to use. This may make disaster recovery much faster, but will also be more expensive. And a school district can afford to be down for several hours before resuming IT operations, so the less expensive option is more appropriate. Answer C is incorrect. A warm site is between a hot and cold site. It has some equipment ready and connectivity ready. However, it is still significantly more expensive than a cold site, and not necessary for this scenario. Answer B is incorrect. Off site is not any type of backup site terminology.
Which of the following authentication methods is used to access public areas of a Web site?
Anonymous authentication is an authentication method used for Internet communication. It provides limited access to specific public folders and directory information or public areas of a Web site. It is supported by all clients and is used to access unsecured content in public folders. An administrator must create a user account in IIS to enable the user to connect anonymously. Answer D is incorrect. Multi-factor authentication involves a combination of multiple methods of authentication. For example, an authentication method that uses smart cards as well as usernames and passwords can be referred to as multi-factor authentication. Answer C is incorrect. Mutual authentication is a process in which a client process and server are required to prove their identities to each other before performing any application function. The client and server identities can be verified through a trusted third party and use shared secrets as in the case of Kerberos v5. The MS-CHAP v2 and EAP-TLS authentication methods support mutual authentication.Answer B is incorrect. Biometrics authentication uses physical characteristics, such as fingerprints, scars, retinal patterns, and other forms of biophysical qualities to identify a user.
