John works as a professional Ethical Hacker. He has been assigned the project of testing the security of www.we-are-secure.com. He finds that the We-are-secure server is vulnerable to attacks. As a countermeasure, he suggests that the Network Administrator should remove the IPP printing capability from the server. He is suggesting this as a countermeasure against __________.
Correct Answer: B
Explanation/Reference: Explanation: 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. AnswerD 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. AnswerA 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 AnswerC 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
Question 132
There are seven risks responses that a project manager can choose from. Which risk response is appropriate for both positive and negative risk events?
Correct Answer: A
Explanation/Reference: Explanation: Only acceptance is appropriate for both positive and negative risk events. Often sharing is used for low probability and low impact risk events regardless of the positive or negative effects the risk event may bring the project. Acceptance response is a part of Risk Response planning process. Acceptance response delineates that the project plan will not be changed to deal with the risk. Management may develop a contingency plan if the risk does occur. Acceptance response to a risk event is a strategy that can be used for risks that pose either threats or opportunities. Acceptance response can be of two types: Passive acceptance: It is a strategy in which no plans are made to try or avoid or mitigate the risk. Active acceptance: Such responses include developing contingency reserves to deal with risks, in case they occur. Acceptance is the only response for both threats and opportunities. Answer: C is incorrect. Sharing is a positive risk response that shares an opportunity for all parties involved in the risk event. Answer: B is incorrect. Transference is a negative risk event that transfers the risk ownership to a third party, such as vendor, through a contractual relationship. Answer: D is incorrect. Mitigation is a negative risk event that seeks to lower the probability and/or impact of a risk event.
Question 133
Which of the following sections come under the ISO/IEC 27002 standard?
Correct Answer: A,B,D
Explanation/Reference: Explanation: ISO/IEC 27002 is an information security standard published by the International Organization for Standardization (ISO) and by the International Electrotechnical Commission (IEC) as ISO/IEC 17799:2005. This standard contains the following twelve main sections: 1.Risk assessment: It refers to assessment of risk. 2.Security policy: It deals with the security management. 3.Organization of information security: It deals with governance of information security. 4.Asset management: It refers to inventory and classification of information assets. 5.Human resources security: It deals with security aspects for employees joining, moving and leaving an organization. 6.Physical and environmental security: It is related to protection of the computer facilities. 7.Communications and operations management: It is the management of technical security controls in systems and networks. 8.Access control: It deals with the restriction of access rights to networks, systems, applications, functions and data. 9.Information systems acquisition, development and maintenance: It refers to build security into applications. 10.Information security incident management: It refers to anticipate and respond appropriately to information security breaches. 11.Business continuity management: It deals with protecting, maintaining and recovering business-critical processes and systems. 12.Compliance: It is used for ensuring conformance with information security policies, standards, laws and regulations. AnswerC is incorrect. Financial assessment does not come under the ISO/IEC 27002 standard.
Question 134
Which of the following areas of information system, as separated by Information Assurance Framework, is a collection of local computing devices, regardless of physical location, that are interconnected via local area networks (LANs) and governed by a single security policy?
Correct Answer: D
Explanation/Reference: Explanation: The areas of information system, as separated by Information Assurance Framework, are as follows: Local Computing Environments: This area includes servers, client workstations, operating system, and applications. Enclave Boundaries: This area consists of collection of local computing devices, regardless of physical location, that are interconnected via local area networks (LANs) and governed by a single security policy. Networks and Infrastructures: This area provides the network connectivity between enclaves. It includes operational area networks (OANs), metropolitan area networks (MANs), and campus area networks (CANs). Supporting Infrastructures: This area provides security services for networks, client workstations, Web servers, operating systems, applications, files, and single-use infrastructure machines
