A. FISMA has been around since 2002 and was updated in 2014. It gave certain information security responsibilities to NIST, OMB, and other government agencies, and declared the Department of Homeland Security (DHS) as the operational lead for budgets and guidelines on security matters.
An ethical hacker is hired to test the security of a business network. The CEH is given no prior knowledge of the network and has a specific framework in which to work, defining boundaries, nondisclosure agreements, and the completion date. Which of the following is a true statement? A. A white hat is attempting a black-box test. B. A white hat is attempting a white-box test. C. A black hat is attempting a black-box test. D. A black hat is attempting a gray-boxy test.
A. In this example, an ethical hacker was hired under a specific agreement, making him a white hat. The test he was hired to perform is a no-knowledge attack, making it a black-box test.
Your company has a document that spells out exactly what employees are allowed to do on their computer systems. It also defines what is prohibited and what consequences await those who break the rules. A copy of this document is signed by all employees prior to their network access. Which of the following best describes this policy? A. Information Security Policy B. Special Access Policy C. Information Audit Policy D. Network Connection Policy
A. The Information Security Policy defines what is allowed and not allowed, and what the consequences are for misbehavior in regard to resources on the corporate network. Generally this is signed by employees prior to their account creation.
What are the 7 layers of the OSI model?

What are the four layers of the TCP/IP stack?
Application, Transport, Internet, Network Access
Joe is a security engineer for a firm. His company downsizes, and Joe discovers he will be laid off within a short amount of time. Joe plants viruses and sets about destroying data and settings throughout the network, with no regard to being caught. Which type of hacker is Joe considered to be? A. Hactivist B. Suicide hacker C. Black hat D. Script kiddie
B. A suicide hacker doesn't care about being caught. Jail time and punishment mean nothing to these guys. While sometimes they are tied to a political or religious group or function, sometimes they're just angry folks looking to make an entity pay for some perceived wrongdoing.
Which type of attack is generally conducted as an inside attacker with elevated privileges on the resources? A. Gray box B. White box C. Black box D. Active reconnaissance
B. A white-box attack is intended to simulate an internal attacker with elevated privileges, such as a network administrator.
Brad has done some research and determined a certain set of systems on his network fail once every ten years. The purchase price for each of these systems is $1200. Additionally, Brad discovers the administrators on staff, who earn $50 an hour, estimate five hours to replace a machine. Five employees, earning $25 an hour, depend on each system and will be completely unproductive while it is down. If you were to ask Brad for an ALE on these devices, what should he answer with? A. $2075 B. $207.50 C. $120 D. $1200
B. ALE = ARO x SLE. To determine ARO, divide the number of occurrences by the number of years (1 occurrence /10 years = 0.1). To determine SLE, add the purchase cost (1200) plus the amount of time to replace (5 x 50 = 250) plus the amount of lost work (5 hours x 5 employees x 25 =625). In this case, it all adds up to $2075. ALE = 0.1 x 2075, or 207.50
Which of the following best describes an effort to identify systems that are critical for continuation of operations for the organization? A. BCP B. BIA C. MTD D. DRP
B. The Business Impact Analysis best matches this description. Although maximum tolerable downtime is part of the process, and a continuity plan certainly addresses it, a BIA is the actual process to identify those critical systems.
Sally is a member of a pen test team newly hired to test a bank's security. She begins searching for IP addresses the bank may own by searching public records on the Internet. She also looks up news articles and job postings to discover information that may be valuable. What phase of the pen test is Sally working? A. Preparation B. Assessment C. Conclusion D. Reconnaissance
B. The assessment phase, which EC-Council also likes to interchangeably denote as the "conduct" phase sometimes, is where all the activity takes place--including the passive information gathering performed by Sally in this example.
In which stage of an ethical hack would the attacker actively apply tools and techniques to gather more in-depth information on the targets? A. Active reconnaissance B. Scanning and enumeration C. Gaining Access D. Passive reconnaissance
B. The second of the five phases of an ethical hack attempt, scanning and enumeration, is the step where ethical hackers take the information they gathered in recon and actively apply tools and techniques to gather more in-depth information on the targets.
Elements of security include confidentiality, integrity, and availability. Which technique provides for integrity? A. Encryption B. UPS C. Hashing D. Passwords
C. A hash is a unique numerical string, created by a hashing algorithm on a given piece of data, used to verify data integrity. Generally, hashes are used to verify the integrity of files after download (comparison to the hash value on the site before download) and/or to store password values. Hashes are created by a one-way algorithm.
Which of the following would be the best example of a deterrent Control? A. A log aggregation system B. Hidden cameras on site C. A guard Posted outside the door D. Backup recovery systems
C. If you're doing something as a deterrent, you're trying to prevent an attack in the first place. In this physical security deterrent control, a guard visible outside the door could help prevent physical attacks.
When an attack by a hacker is politically motivated, the hacker is said to be participating in which of the following? A. Black-hat hacking B. Gray-Box attacks C. Gray-hat attacks D. Hactivism
D. Hackers who use their skills and talents to forward a cause or a political agenda are practicing hactivism.
Two hackers attempt to crack a company's network resource security. One is considered an ethical hacker, whereas the other is not. What distinguishes the ethical hacker from the "cracker"? A. The cracker always attempts white-box testing. B. The ethical hacker always attempts black-box testing. C. The cracker posts results to the Internet. D. The ethical hacker always obtains written permission before testing.
