Question No: 101 – (Topic 1)

Two universities are making their 802.11n wireless networks available to the other university’s students. The infrastructure will pass the student’s credentials back to the home school for authentication via the Internet.

The requirements are:

The following design was implemented:

WPA2 Enterprise using EAP-PEAP-MSCHAPv2 will be used for wireless security RADIUS proxy servers will be used to forward authentication requests to the home school The RADIUS servers will have certificates from a common public certificate authority

Question No: 104 – (Topic 1)

A developer has implemented a piece of client-side JavaScript code to sanitize a user’s provided input to a web page login screen. The code ensures that only the upper case and lower case letters are entered in the username field, and that only a 6-digit PIN is entered in the password field. A security administrator is concerned with the following web server log:

10.235.62.11 – – [02/Mar/2014:06:13:04] “GET

/site/script.php?user=adminamp;pass=pass or 1=1 HTTP/1.1″ 200 5724

Given this log, which of the following is the security administrator concerned with and which

fix should be implemented by the developer?

  1. The security administrator is concerned with nonprintable characters being used to gain administrative access, and the developer should strip all nonprintable characters.

  2. The security administrator is concerned with XSS, and the developer should normalize Unicode characters on the browser side.

  3. The security administrator is concerned with SQL injection, and the developer should implement server side input validation.

  4. The security administrator is concerned that someone may log on as the administrator, and the developer should ensure strong passwords are enforced.

Answer: C

Question No: 105 – (Topic 1)

A new internal network segmentation solution will be implemented into the enterprise that consists of 200 internal firewalls. As part of running a pilot exercise, it was determined that it takes three changes to deploy a new application onto the network before it is operational. Security now has a significant effect on overall availability. Which of the following would be the FIRST process to perform as a result of these findings?

  1. Lower the SLA to a more tolerable level and perform a risk assessment to see if the solution could be met by another solution. Reuse the firewall infrastructure on other projects.

  2. Perform a cost benefit analysis and implement the solution as it stands as long as the risks are understood by the business owners around the availability issues. Decrease the current SLA expectations to match the new solution.

  3. Engage internal auditors to perform a review of the project to determine why and how the project did not meet the security requirements. As part of the review ask them to review the control effectiveness.

  4. Review to determine if control effectiveness is in line with the complexity of the solution. Determine if the requirements can be met with a simpler solution.

Answer: D

Question No: 106 – (Topic 1)

The Chief Information Security Officer (CISO) at a company knows that many users store business documents on public cloud-based storage, and realizes this is a risk to the company. In response, the CISO implements a mandatory training course in which all

  2. Accept

  3. Mitigate

  4. Transfer

Answer: C

Question No: 107 – (Topic 1)

A security administrator notices a recent increase in workstations becoming compromised by malware. Often, the malware is delivered via drive-by downloads, from malware hosting websites, and is not being detected by the corporate antivirus. Which of the following solutions would provide the BEST protection for the company?

  1. Increase the frequency of antivirus downloads and install updates to all workstations.

  2. Deploy a cloud-based content filter and enable the appropriate category to prevent further infections.

  3. Deploy a WAF to inspect and block all web traffic which may contain malware and exploits.

Question No: 110 – (Topic 1)

The Information Security Officer (ISO) believes that the company has been targeted by cybercriminals and it is under a cyber attack. Internal services that are normally available to the public via the Internet are inaccessible, and employees in the office are unable to browse the Internet. The senior security engineer starts by reviewing the bandwidth at the border router, and notices that the incoming bandwidth on the router’s external interface is maxed out. The security engineer then inspects the following piece of log to try and determine the reason for the downtime, focusing on the company’s external router’s IP which is 128.20.176.19:

11:16:22.110343 IP 90.237.31.27.19 gt; 128.20.176.19.19: UDP, length 1400

11:16:22.110351 IP 23.27.112.200.19 gt; 128.20.176.19.19: UDP, length 1400

11:16:22.110358 IP 192.200.132.213.19 gt; 128.20.176.19.19: UDP, length 1400

11:16:22.110402 IP 70.192.2.55.19 gt; 128.20.176.19.19: UDP, length 1400

11:16:22.110406 IP 112.201.7.39.19 gt; 128.20.176.19.19: UDP, length 1400

Which of the following describes the findings the senior security engineer should report to the ISO and the BEST solution for service restoration?

  1. After the senior engineer used a network analyzer to identify an active Fraggle attack, the company’s ISP should be contacted and instructed to block the malicious packets.

  2. After the senior engineer used the above IPS logs to detect the ongoing DDOS attack, an IPS filter should be enabled to block the attack and restore communication.

  3. After the senior engineer used a mirror port to capture the ongoing amplification attack, a BGP sinkhole should be configured to drop traffic at the source networks.

  4. After the senior engineer used a packet capture to identify an active Smurf attack, an ACL should be placed on the company’s external router to block incoming UDP port 19 traffic.
