QUESTION 51
An insurance company has two million customers and is researching the top transactions on its customer portal. It identifies that the top transaction is currently password reset. Due to users not remembering their secret questions, a large number of calls are consequently routed to the contact center for manual password resets.

B. Customer ID sent via push notification
C. SMS with OTP sent to a mobile number
D. Third-party social login

Answer: CE

QUESTION 52
A security architect is implementing security measures in response to an external audit that found vulnerabilities in the corporate collaboration tool suite. The report identified the lack of any mechanism to provide confidentiality for electronic correspondence between users and between users and group mailboxes. Which of the following controls would BEST mitigate the identified vulnerability?

A. Issue digital certificates to all users, including owners of group mailboxes, and enable S/MIME
B. Federate with an existing PKI provider, and reject all non-signed emails
C. Implement two-factor email authentication, and require users to hash all email messages upon receipt
D. Provide digital certificates to all systems, and eliminate the user group or shared mailboxes

Answer: A

QUESTION 53
The Chief Executive Officer (CEO) of an Internet service provider (ISP) has decided to limit the company’s contribution to worldwide Distributed Denial of Service (DDoS) attacks. Which of the following should the ISP implement? (Select TWO).

A. Block traffic from the ISP’s networks destined for blacklisted IPs.
B. Prevent the ISP’s customers from querying DNS servers other than those hosted by the ISP.
C. Scan the ISP’s customer networks using an up-to-date vulnerability scanner.
D. Notify customers when services they run are involved in an attack.
E. Block traffic with an IP source not allocated to customers from exiting the ISP’s network.

Answer: DE
Explanation:
Since DDOS attacks can originate from nay different devices and thus makes it harder to defend against, one way to limit the company’s contribution to DDOS attacks is to notify customers about any DDOS attack when they run services that are under attack. The company can also block IP sources that are not allocated to customers from the existing SIP’s network.

QUESTION 54
The latest independent research shows that cyber attacks involving SCADA systems grew an average of 15% per year in each of the last four years, but that this year’s growth has slowed to around 7%. Over the same time period, the number of attacks against applications has decreased or stayed flat each year. At the start of the measure period, the incidence of PC boot loader or BIOS based attacks was negligible. Starting two years ago, the growth in the number of PC boot loader attacks has grown exponentially. Analysis of these trends would seem to suggest which of the following strategies should be employed?

A. Spending on SCADA protections should stay steady; application control spending should increase substantially and spending on PC boot loader controls should increase substantially.
B. Spending on SCADA security controls should stay steady; application control spending should decrease slightly and spending on PC boot loader protections should increase substantially.
C. Spending all controls should increase by 15% to start; spending on application controls should be suspended, and PC boot loader protection research should increase by 100%.
D. Spending on SCADA security controls should increase by 15%; application control spending should increase slightly, and spending on PC boot loader protections should remain steady.

Answer: B
Explanation:
Spending on the security controls should stay steady because the attacks are still ongoing albeit reduced in occurrence Due to the incidence of BIOS-based attacks growing exponentially as the application attacks being decreased or staying flat spending should increase in this field.

QUESTION 55
A small company is developing a new Internet-facing web application.
The security requirements are:
Users of the web application must be uniquely identified and authenticated.
Users of the web application will not be added to the company’s directory services.
Passwords must not be stored in the code.
Which of the following meets these requirements?

A. Use OpenID and allow a third party to authenticate users.
B. Use TLS with a shared client certificate for all users.
C. Use SAML with federated directory services.
D. Use Kerberos and browsers that support SAML.

Answer: A
Explanation:
Users create accounts by selecting an OpenID identity provider, and then use those accounts to sign onto any website which accepts OpenID authentication. OpenID is an open standard and decentralized protocol by the non-profit OpenID Foundation that allows users to be authenticated by certain co-operating sites (known as Relying Parties or RP) using a third party service. This eliminates the need for webmasters to provide their own ad hoc systems and allowing users to consolidate their digital identities. In other words, users can log into multiple unrelated websites without having to register with their information over and over again. Several large organizations either issue or accept OpenIDs on their websites according to the OpenID Foundation: AOL, Blogger, Flickr, France Telecom, Google, Hyves, LiveJournal, Microsoft (provider name Microsoft account), Mixi, Myspace, Novell, Orange, Sears, Sun, Telecom Italia, Universal Music Group, VeriSign, WordPress, and Yahoo!. Other providers include BBC, IBM, PayPal, and Steam.
