B. Federate identity management systems.
C. Install firewalls between the businesses.
D. Re-image all end user computers to a standard image.

Answer: E, F

QUESTION NO: 2
A trucking company delivers products all over the country. The executives at the company would like to have better insight into the location of their drivers to ensure the shipments are following secure routes.
Which of the following would BEST help the executives meet this goal?
A. Install GSM tracking on each product for end-to-end delivery visibility.
B. Implement geo-fencing to track products.
C. Require drivers to geo-tag documentation at each delivery location.
D. Equip each truck with an RFID tag for location services.
Answer: B
Explanation:
A Geo-fencing solution would use GPS to track the vehicles and could be configured to inform the executives where the vehicles are.
Geo-fencing is a feature in a software program that uses the global positioning system (GPS) or radio frequency identification (RFID) to define geographical boundaries. A geo-fence is a virtual barrier.
Programs that incorporate geo-fencing allow an administrator to set up triggers so when a device enters
(or exits) the boundaries defined by the administrator, a text message or email alert is sent.
Many geo-fencing applications incorporate Google Earth, allowing administrators to define boundaries on top of a satellite view of a specific geographical area. Other applications define boundaries by longitude and latitude or through user-created and Web-based maps.
Incorrect Answers:
A: GSM tracking tracks a mobile phone by detecting the phone's radio signals between radio towers.
This solution would require there to be radio towers within range of the phone at all times. This is not always the case when travelling across country. GPS uses satellites which is a better solution.
C: Requiring drivers to geo-tag documentation at each delivery location would provide information when the driver is at a delivery location. However, it would not provide information when the driver is travelling between delivery locations.
D: An RFID tag requires an RFID reader to read the tag. This could work within a building where RFID readers could be installed. However, it is not a practical solution out on the open road as there would be no RFID readers.

QUESTION NO: 3
A security engineer is responsible for monitoring company applications for known vulnerabilities.
Which of the following is a way to stay current on exploits and information security news?
A. Update company policies and procedures
B. Subscribe to security mailing lists
C. Implement security awareness training
D. Ensure that the organization vulnerability management plan is up-to-date
Answer: B
Explanation:
Subscribing to bug and vulnerability, security mailing lists is a good way of staying abreast and keeping up to date with the latest in those fields.
Incorrect Answers:
A: Updating company policies and procedures are not staying current on the topic since attacks are generated from outside sources and the best way to stay current on what is happening in that particular topic is to subscribe to a mailing list on the topic.
C: Security awareness training serves best as an operational control insofar as mitigating risk is concerned and not to stay current on the topic.
D: Making sure the company vulnerability plan is up to date is essential but will not keep you up to date on the topic as a subscription to a security mailing list.

QUESTION NO: 4
A security administrator is tasked with increasing the availability of the storage networks while enhancing the performance of existing applications. Which of the following technologies should the administrator implement to meet these goals? (Select TWO).
A. LUN masking
B. Snapshots
C. vSAN
D. Dynamic disk pools
E. Multipath
F. Deduplication
Answer: D, E
Explanation:
We can use dynamic disk pools (DDP) to increase availability and improve performance compared to traditional RAID. Multipathing also improves availability by creating multiple paths to the storage (in case one path fails) and it improves the performance by aggregating the performance of the multiple paths.
DDP dynamically distributes all data, spare capacity, and protection information across a pool of drives.
Effectively, DDP is a new type of RAID level, built on RAID 6. It uses an intelligent algorithm to define where each chunk of data should reside. In traditional RAID, drives are organized into arrays, and logical drives are written across stripes on the physical drives in the array. Hot spares contain no data until a drive fails, leaving that spare capacity stranded and without a purpose. In the event of a drive failure, the data is recreated on the hot spare, significantly impacting the performance of all drives in the array during the rebuild process.
With DDP, each logical drive's data and spare capacity is distributed across all drives in the pool, so all drives contribute to the aggregate 10 of the logical drive, and the spare capacity is available to all logical drives. In the event of a physical drive failure, data is reconstructed throughout the disk pool.
Basically, the data that had previously resided on the failed drive is redistributed across all drives in the pool. Recovery from a failed drive may be up to ten times faster than a rebuild in a traditional
RAID set, and the performance degradation is much less during the rebuild.
In computer storage, multipath 1/0 is a fault-tolerance and performance-enhancement technique that defines more than one physical path between the CPU in a computer system and its massstorage devices through the buses, controllers, switches, and bridge devices connecting them.
As an example, a SCSI hard disk drive may connect to two SCSI controllers on the same computer, or a disk may connect to two Fibre Channel ports. Should one controller, port or switch fail, the operating system can route the 1/0 through the remaining controller, port or switch transparently and with no changes visible to the applications.
Incorrect Answers:
A: LUN masking is used to control which LUNs are visible to specific servers. It does not improve the availability of the storage networks or the performance of existing applications.
B: A snapshot is a point in time image of the data on a SAN used for backup or recovery purposes. It does not improve the availability of the storage networks or the performance of existing applications.
C: A vSAN is local storage on hypervisor servers combined together to create a "virtual SAN". A vSAN does not improve the availability of the storage networks or the performance of existing applications.
F: Deduplication is the process of eliminating multiple copies of the same data to save storage space.
It does not improve the availability of the storage networks or the performance of existing applications.

QUESTION NO: 5
An insurance company has an online quoting system for insurance premiums. It allows potential customers to fill in certain details about their car and obtain a quote. During an investigation, the following patterns were detected:
Pattern 1 - Analysis of the logs identifies that insurance premium forms are being filled in but only single fields are incrementally being updated.
Pattern 2 - For every quote completed, a new customer number is created; due to legacy systems, customer numbers are running out.
Which of the following is the attack type the system is susceptible to, and what is the BEST way to defend against it? (Select TWO).
A. Apply a hidden field that triggers a SIEM alert
B. Cross site scripting attack
C. Resource exhaustion attack
D. Input a blacklist of all known BOT malware IPs into the firewall
E. SQL injection
F. Implement an inline WAF and integrate into SIEM
G. Distributed denial of service
H. Implement firewall rules to block the attacking IP addresses
Answer: C, F
Explanation:
A resource exhaustion attack involves tying up predetermined resources on a system, thereby making the resources unavailable to others.
Implementing an inline WAF would allow for protection from attacks, as well as log and alert admins to what's going on. Integrating in into SIEM allows for logs and other security-related documentation to be collected for analysis.
Incorrect Answers:
A: SIEM technology analyses security alerts generated by network hardware and applications.
B: Cross site scripting attacks occur when malicious scripts are injected into otherwise trusted websites.
D: Traditional firewalls block or allow traffic. It is not, however, the best way to defend against a resource exhaustion attack.
E: A SQL injection attack occurs when the attacker makes use of a series of malicious SQL queries to directly influence the SQL database.
G: A distributed denial-of-service (DDoS) attack occurs when many compromised systems attack a single target. This results in denial of service for users of the targeted system.
H: Traditional firewalls block or allow traffic. It is not, however, the best way to defend against a resource exhaustion attack.
