The Chief Information Officer (CIO) wants to implement a redundant server location to which the production server images can be moved within 48 hours and services can be quickly restored, in case of a catastrophic failure of the primary datacenter\’s HVAC. Which of the following can be implemented?
A. Cold site
B. Load balancing
C. Warm site
D. Hot site
Correct Answer: C
Warm sites provide computer systems and compatible media capabilities. If a warm site is used, administrators and other staff will need to install and configure systems to resume operations. For most organizations, a warm site could be a remote office, a leased facility, or another organization with which yours has a reciprocal agreement.
A security technician wishes to gather and analyze all Web traffic during a particular time period.
Which of the following represents the BEST approach to gathering the required data?
A. Configure a VPN concentrator to log all traffic destined for ports 80 and 443.
B. Configure a proxy server to log all traffic destined for ports 80 and 443.
C. Configure a switch to log all traffic destined for ports 80 and 443.
D. Configure a NIDS to log all traffic destined for ports 80 and 443.
Correct Answer: B
A proxy server is in essence a device that acts on behalf of others and in security terms all internal user interaction with the Internet should be controlled through a proxy server. This makes a proxy server the best tool to gather the required data.
A security administrator has concerns about new types of media which allow for the mass distribution of personal comments to a select group of people. To mitigate the risks involved with this media, employees should receive training on which of the following?
A. Peer to Peer
B. Mobile devices
C. Social networking
D. Personally owned devices
Correct Answer: C
There many companies that allow full use of social media in the workplace, believing that the marketing opportunities it holds outweigh any loss in productivity. What they are unknowingly minimizing are the threats that exist. Rather than being all new threats, the social networking/media threats tend to fall in the categories of the same old tricks used elsewhere but in a new format. A tweet can be sent with a shortened URL so that it does not exceed the 140-character limit set by Twitter; unfortunately, the user has no idea what the shortened URL leads to. This makes training your employees regarding the risks social networking entails essential.
Which of the following types of risk reducing policies also has the added indirect benefit of cross training employees when implemented?
A. Least privilege
B. Job rotation
C. Mandatory vacations
D. Separation of duties
Correct Answer: B
A job rotation policy defines intervals at which employees must rotate through positions. Similar in purpose to mandatory vacations, it helps to ensure that the company does not become too dependent on one person and it does afford the company with the opportunity to place another person in that same job.
Which of the following is an attack vector that can cause extensive physical damage to a datacenter without physical access?
A. CCTV system access
B. Dial-up access
C. Changing environmental controls
D. Ping of death
Correct Answer: C
Environmental systems include heating, air conditioning, humidity control, fire suppression, and power systems. All of these functions are critical to a well-designed physical plant. A computer room will typically require full-time environmental control. Changing any of these controls (when it was set to its optimum values) will result in damage.
A security engineer is given new application extensions each month that need to be secured prior to implementation. They do not want the new extensions to invalidate or interfere with existing application security. Additionally, the engineer wants to ensure that the new requirements are approved by the appropriate personnel. Which of the following should be in place to meet these two goals? (Select TWO).
A. Patch Audit Policy
B. Change Control Policy
C. Incident Management Policy
D. Regression Testing Policy
E. Escalation Policy
F. Application Audit Policy
Correct Answer: BD
A backout (regression testing) is a reversion from a change that had negative consequences. It could be, for example, that everything was working fi ne until you installed a service pack on a production machine, and then services that were normally available were no longer accessible. The backout, in this instance, would revert the system to the state that it was in before the service pack was applied. Backout plans can include uninstalling service packs, hotfi xes, and patches, but they can also include reversing a migration and using previous firmware. A key component to creating such a plan is identifying what events will trigger your implementing the backout. A change control policy refers to the structured approach that is followed to secure a company\’s assets in the event of changes occurring.
After an assessment, auditors recommended that an application hosting company should contract with additional data providers for redundant high speed Internet connections. Which of the following is MOST likely the reason for this recommendation? (Select TWO).
A. To allow load balancing for cloud support
B. To allow for business continuity if one provider goes out of business
C. To eliminate a single point of failure
D. To allow for a hot site in case of disaster
E. To improve intranet communication speeds
Correct Answer: BC
A high-speed internet connection to a second data provider could be used to keep an up- to-date replicate of the main site. In case of problem on the first site, operation can quickly switch to the second site. This eliminates the single point of failure and allows the business to continue uninterrupted on the second site. Note: Recovery Time Objective The recovery time objective (RTO) is the maximum amount of time that a process or service is allowed to be down and the consequences still be considered acceptable. Beyond this time, the break in business continuity is considered to affect the business negatively. The RTO is agreed on during BIA creation.
Sara, the Chief Security Officer (CSO), has had four security breaches during the past two years.
Each breach has cost the company $3,000. A third party vendor has offered to repair the security hole in the system for $25,000. The breached system is scheduled to be replaced in five years.
Which of the following should Sara do to address the risk?
A. Accept the risk saving $10,000.
B. Ignore the risk saving $5,000.
C. Mitigate the risk saving $10,000.
D. Transfer the risk saving $5,000.
Correct Answer: D
Risk transference involves sharing some of the risk burden with someone else, such as an insurance company. The cost of the security breach over a period of 5 years would amount to $30,000 and it is better to save $5,000.
A company has two server administrators that work overnight to apply patches to minimize disruption to the company. With the limited working staff, a security engineer performs a risk assessment to ensure the protection controls are in place to monitor all assets including the administrators in case of an emergency. Which of the following should be in place?
Correct Answer: B
CCTV are an excellent way to deter unwanted activity and it records the occurrence of the event, in case it does happen. Cameras can be placed to watch points of entry, to monitor activities around valuable assets as well as provide additional protection in areas such as parking areas and walkways.
A company is trying to implement physical deterrent controls to improve the overall security posture of their data center. Which of the following BEST meets their goal?
A. Visitor logs
C. Hardware locks
D. Environmental monitoring
Correct Answer: C
Hardware security involves applying physical security modifications to secure the system(s) and preventing them from leaving the facility. Don\’t spend all of your time worrying about intruders coming through the network wire while overlooking the obvious need for physical security. Hardware security involves the use of locks to prevent someone from picking up and carrying out your equipment.
