A disaster recovery plan is a complete statement of reliable actions to be taken before, during, and after a disruptive event that causes a considerable loss of information systems resources. The chief objective of a disaster recovery plan is to provide an organized way to make decisions if a disruptive event occurs. 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: D is incorrect. 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. 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. Answer: A 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.

Removing the IPP printing capability from a server is a good countermeasure against an IIS buffer overflow attack. A Network Administrator should take the following steps to prevent a Web server from IIS buffer overflow attacks: Conduct frequent scans for server vulnerabilities. Install the upgrades of Microsoft service packs.

Implement effective firewalls. Apply URLScan and IISLockdown utilities. Remove the IPP printing capability. Answer: D is incorrect. The following are the DNS zone transfer countermeasures: Do not allow DNS zone transfer using the DNS property sheet: a.Open DNS. b.Right-click a DNS zone and click Properties. c.On the Zone Transfer tab, clear the Allow zone transfers check box. Configure the master DNS server to allow zone transfers only from secondary DNS servers: a.Open DNS. b.Right-click a DNS zone and click Properties. c.On the zone transfer tab, select the Allow zone transfers check box, and then do one of the following: To allow zone transfers only to the DNS servers listed on the name servers tab, click on the Only to the servers listed on the Name Server tab. To allow zone transfers only to specific DNS servers, click Only to the following servers, and add the IP address of one or more servers. Deny all unauthorized inbound connections to TCP port 53. Implement DNS keys and encrypted DNS payloads. Answer: A is incorrect. The following are the countermeasures against SNMP enumeration: 1.Removing the SNMP agent or disabling the SNMP service 2.Changing the default PUBLIC community name when 'shutting off SNMP' is not an option 3.Implementing the Group Policy security option called Additional restrictions for anonymous connections 4.Restricting access to NULL session pipes and NULL session shares 5.Upgrading SNMP Version 1 with the latest version 6.Implementing Access control list filtering to allow only access to the read-write community from approved stations or subnets Answer: C is incorrect. NetBIOS NULL session vulnerabilities are hard to prevent, especially if NetBIOS is needed as part of the infrastructure. One or more of the following steps can be taken to limit NetBIOS NULL session vulnerabilities: 1.Null sessions require access to the TCP 139 or TCP 445 port, which can be disabled by a Network Administrator. 2.A Network Administrator can also disable SMB services entirely on individual hosts by unbinding WINS Client TCP/IP from the interface. 3.A Network Administrator can also restrict the anonymous user by editing the registry values: a.Open regedit32, and go to HKLM\SYSTEM\CurrentControlSet\LSA. b.Choose edit > add value. Value name: RestrictAnonymous Data Type: REG_WORD Value: 2

FISMA defines the following three security objectives for information and information systems: Confidentiality: It means that the data should only be accessible to authorized users. Access includes printing, displaying, and other such forms of disclosure, including simply revealing the existence of an object. Integrity: It means that only authorized users are able to modify data. Modification admits changing, changing the status, deleting, and creating. Availability: It means that the data should only be available to authorized users. Answer: A is incorrect. Authenticity is not defined by the FISMA as one of the security objectives for information and information systems.
