  Select and Place:

  A. Phishing.

  B. Whaling.

  C. Vishing.

  D. Spim.

  E. Social engineering.

  A: Phishing is the act of sending an email to a user falsely claiming to be an established legitimate enterprise in an attempt to scam the user into surrendering private information that will be used for identity theft.

  Phishing email will direct the user to visit a website where they are asked to update personal information, such as a password, credit card, social security, or bank account numbers, that the legitimate organization already has. The website,

  however, is bogus and set up only to steal the information the user enters on the page.

  B: Whaling is a specific kind of malicious hacking within the more general category of phishing, which involves hunting for data that can be used by the hacker. In general, phishing efforts are focused on collecting personal data about users. In

  whaling, the targets are high-ranking bankers, executives or others in powerful positions or job titles.

  Hackers who engage in whaling often describe these efforts as "reeling in a big fish,"applying a familiar metaphor to the process of scouring technologies for loopholes and opportunities for data theft. Those who are engaged in whaling may,

  for example, hack into specific networks where these powerful individuals work or store sensitive data. They may also set up keylogging or other malware on a work station associated with one of these executives. There are many ways that

  hackers can pursue whaling, leading C-level or toplevel executives in business and government to stay vigilant about the possibility of cyber threats.

  C: Vishing is the act of using the telephone in an attempt to scam the user into surrendering private information that will be used for identity theft. The scammer usually pretends to be a legitimate business, and fools the victim into thinking he

  or she will profit.

  D: SPIM is a term sometimes used to refer to spam over IM (Instant Messaging). It's also called just spam, instant spam, or IM marketing. No matter what the name, it consists of unwanted messages transmitted through some form of instant

  messaging service, which can include Short Message Service (SMS).

  E: Social engineering is a non-technical method of intrusion hackers use that relies heavily on human interaction and often involves tricking people into breaking normal security procedures. It is one of the greatest threats that organizations

  today encounter.

  A social engineer runs what used to be called a "con game." For example, a person using social engineering to break into a computer network might try to gain the confidence of an authorized user and get them to reveal information that

  compromises the network's security. Social engineers often rely on the natural helpfulness of people as well as on their weaknesses. They might, for example, call the authorized employee with some kind of urgent problem that requires

  immediate network access. Appealing to vanity, appealing to authority, appealing to greed, and old-fashioned eavesdropping are other typical social engineering techniques.

• Question 1314:

  Task: Configure the firewall (fill out the table) to allow these four rules:

  Only allow the Accounting computer to have HTTPS access to the Administrative server.

  Only allow the HR computer to be able to communicate with the Server 2 System over SCP.

  Allow the IT computer to have access to both the Administrative Server 1 and Administrative Server 2

  

  Correct Answer. Check the answer below
  Check the answer below

  Use the following answer for this simulation task.

  Below table has all the answers required for this question.

  

  Firewall rules act like ACLs, and they are used to dictate what traffic can pass between the firewall and the internal network. Three possible actions can be taken based on the rule's criteria: Block the connection Allow the connection Allow the connection only if it is secured TCP is responsible for providing a reliable, one-to-one, connection-oriented session. TCP establishes a connection and ensures that the other end receives any packets sent. Two hosts communicate packet results with each other. TCP also ensures that packets are decoded and sequenced properly. This connection is persistent during the session. When the session ends, the connection is torn down. UDP provides an unreliable connectionless communication method between hosts. UDP is considered a best-effort protocol, but it's considerably faster than TCP. The sessions don't establish a synchronized session like the kind used in TCP, and UDP doesn't guarantee error-free communications. The primary purpose of UDP is to send small packets of information. The application is responsible for acknowledging the correct reception of the dat a. Port 22 is used by both SSH and SCP with UDP. Port 443 is used for secure web connections? HTTPS and is a TCP port. Thus to make sure only the Accounting computer has HTTPS access to the Administrative server you should use TCP port 443 and set the rule to allow communication between 10.4.255.10/24 (Accounting) and 10.4.255.101 (Administrative server1) Thus to make sure that only the HR computer has access to Server2 over SCP you need use of TCP port 22 and set the rule to allow communication between 10.4.255.10/23 (HR) and

  10.4.255.2 (server2) Thus to make sure that the IT computer can access both the Administrative servers you need to use a port and accompanying port number and set the rule to allow communication between:

  10.4.255.10.25 (IT computer) and 10.4.255.101 (Administrative server1) 10.4.255.10.25 (IT computer) and 10.4.255.102 (Administrative server2)

• Question 1315:

  A business sector is highly competitive, and safeguarding trade secrets and critical information is paramount. On a seasonal basis, an organization employs temporary hires and contractor personnel to accomplish its mission objectives. The

  A. Employ time-of-day restrictions.
  B. Employ password complexity.
  C. Employ a random key generator strategy.
  D. Employ an account expiration strategy.
  E. Employ a password lockout policy
  D. Employ an account expiration strategy.

• Question 1316:

  A penetration tester is checking to see if an internal system is vulnerable to an attack using a remote listener. Which of the following commands should the penetration tester use to verify if this vulnerability exists? (Choose two.)

  A. tcpdump

  C. nmap
  D. nslookup

  A. Network resources have been exceeded.
  B. The software is out of licenses.
  C. The VM does not have enough processing power.
  D. The firewall is misconfigured.
