Q261. – (Topic 3)
A data processing server uses a Linux based file system to remotely mount physical disks on a shared SAN. The server administrator reports problems related to processing of files where the file appears to be incompletely written to the disk. The network administration team has conducted a thorough review of all network infrastructure and devices and found everything running at optimal performance. Other SAN customers are unaffected. The data being processed consists of millions of small files being written to disk from a network source one file at a time. These files are then accessed by a local Java program for processing before being transferred over the network to a SE Linux host for processing. Which of the following is the MOST likely cause of the processing problem?
A. The administrator has a PERL script running which disrupts the NIC by restarting the CRON process every 65 seconds.
B. The Java developers accounted for network latency only for the read portion of the processing and not the write process.
C. The virtual file system on the SAN is experiencing a race condition between the reads and writes of network files.
D. The Linux file system in use cannot write files as fast as they can be read by the Java program resulting in the errors.
Q262. – (Topic 4)
The security administrator finds unauthorized tables and records, which were not present before, on a Linux database server. The database server communicates only with one web server, which connects to the database server via an account with SELECT only privileges. Web server logs show the following:
22.214.171.124 â – [08/Mar/2014:10:54:04] âGET calendar.php?create%20table%20hidden HTTP/1.1â 200 5724
126.96.36.199 â – [08/Mar/2014:10:54:05] âGET ../../../root/.bash_history HTTP/1.1â 200 188.8.131.52 â – [08/Mar/2014:10:54:04] âGET index.php?user=<script>Create</script> HTTP/1.1â 200 5724
The security administrator also inspects the following file system locations on the database server using the command âls -al /rootâ
drwxrwxrwx 11 root root 4096 Sep 28 22:45 .
drwxr-xr-x 25 root root 4096 Mar 8 09:30 ..
-rws—— 25 root root 4096 Mar 8 09:30 .bash_history
-rw——- 25 root root 4096 Mar 8 09:30 .bash_history
-rw——- 25 root root 4096 Mar 8 09:30 .profile
-rw——- 25 root root 4096 Mar 8 09:30 .ssh
Which of the following attacks was used to compromise the database server and what can the security administrator implement to detect such attacks in the future? (Select TWO).
A. Privilege escalation
B. Brute force attack
C. SQL injection
D. Cross-site scripting
E. Using input validation, ensure the following characters are sanitized. <>
F. Update crontab with: find / \\( -perm -4000 \\) âtype f âprint0 | xargs -0 ls âl | email.sh
G. Implement the following PHP directive: $clean_user_input = addslashes($user_input)
H. Set an account lockout policy
Q263. – (Topic 5)
A new web based application has been developed and deployed in production. A security engineer decides to use an HTTP interceptor for testing the application. Which of the following problems would MOST likely be uncovered by this tool?
A. The tool could show that input validation was only enabled on the client side
B. The tool could enumerate backend SQL database table and column names
C. The tool could force HTTP methods such as DELETE that the server has denied
D. The tool could fuzz the application to determine where memory leaks occur
Q264. – (Topic 5)
After a security incident, an administrator would like to implement policies that would help reduce fraud and the potential for collusion between employees. Which of the following would help meet these goals by having co-workers occasionally audit another worker's position?
A. Least privilege
B. Job rotation
C. Mandatory vacation
D. Separation of duties
Q265. – (Topic 3)
About twice a year a switch fails in a company's network center. Under the maintenance contract, the switch would be replaced in two hours losing the business $1,000 per hour. The cost of a spare switch is $3,000 with a 12-hour delivery time and would eliminate downtime costs if purchased ahead of time. The maintenance contract is $1,500 per year.
Which of the following is true in this scenario?
A. It is more cost-effective to eliminate the maintenance contract and purchase a replacement upon failure.
B. It is more cost-effective to purchase a spare switch prior to an outage and eliminate the maintenance contract.
C. It is more cost-effective to keep the maintenance contract instead of purchasing a spare switch prior to an outage.
D. It is more cost-effective to purchase a spare switch prior to an outage and keep the maintenance contract.
Q266. – (Topic 5)
Executive management is asking for a new manufacturing control and workflow automation solution. This application will facilitate management of proprietary information and closely guarded corporate trade secrets.
The information security team has been a part of the department meetings and come away with the following notes:
-Human resources would like complete access to employee data stored in the application. They would like automated data interchange with the employee management application, a cloud-based SaaS application.
-Sales is asking for easy order tracking to facilitate feedback to customers.
-Legal is asking for adequate safeguards to protect trade secrets. They are also concerned with data ownership questions and legal jurisdiction.
-Manufacturing is asking for ease of use. Employees working the assembly line cannot be bothered with additional steps or overhead. System interaction needs to be quick and easy.
-Quality assurance is concerned about managing the end product and tracking overall performance of the product being produced. They would like read-only access to the entire workflow process for monitoring and baselining.
The favored solution is a user friendly software application that would be hosted onsite. It has extensive ACL functionality, but also has readily available APIs for extensibility. It supports read-only access, kiosk automation, custom fields, and data encryption.
Which of the following departmentsâ request is in contrast to the favored solution?
D. Quality assurance
E. Human resources
Q267. – (Topic 4)
An administrator has four virtual guests on a host server. Two of the servers are corporate SQL servers, one is a corporate mail server, and one is a testing web server for a small group of developers. The administrator is experiencing difficulty connecting to the host server during peak network usage times. Which of the following would allow the administrator to securely connect to and manage the host server during peak usage times?
A. Increase the virtual RAM allocation to high I/O servers.
B. Install a management NIC and dedicated virtual switch.
C. Configure the high I/O virtual servers to use FCoE rather than iSCSI.
D. Move the guest web server to another dedicated host.
Q268. – (Topic 2)
A business unit of a large enterprise has outsourced the hosting and development of a new external website which will be accessed by premium customers, in order to speed up the time to market timeline. Which of the following is the MOST appropriate?
A. The external party providing the hosting and website development should be obligated under contract to provide a secure service which is regularly tested (vulnerability and penetration). SLAs should be in place for the resolution of newly identified vulnerabilities and a guaranteed uptime.
B. The use of external organizations to provide hosting and web development services is not recommended as the costs are typically higher than what can be achieved internally. In addition, compliance with privacy regulations becomes more complex and guaranteed uptimes are difficult to track and measure.
C. Outsourcing transfers all the risk to the third party. An SLA should be in place for the resolution of newly identified vulnerabilities and penetration / vulnerability testing should be conducted regularly.
D. Outsourcing transfers the risk to the third party, thereby minimizing the cost and any legal obligations. An MOU should be in place for the resolution of newly identified vulnerabilities and penetration / vulnerability testing should be conducted regularly.
