CompTIA CompTIA Certifications SY0-501 Questions & Answers

• Question 1401:

  DRAG DROP

  Determine the types of attacks below by selecting an option from the dropdown list. Determine the types of Attacks from right to specific action.

  Select and Place:

  

  Correct Answer:

  

  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 1403:

  DRAG DROP

  A forensic analyst is asked to respond to an ongoing network attack on a server. Place the items in the list below in the correct order in which the forensic analyst should preserve them.

  Select and Place:

  

  Correct Answer:

  

  When dealing with multiple issues, address them in order of volatility (OOV); always deal with the most volatile first. Volatility can be thought of as the amount of time that you have to collect certain data before a window of opportunity is gone.

  Naturally, in an investigation you want to collect everything, but some data will exist longer than others, and you cannot possibly collect all of it once. As an example, the OOV in an investigation may be RAM, hard drive data, CDs/DVDs, and

  printouts.

  Order of volatility: Capture system images as a snapshot of what exists, look at network traffic and logs, capture any relevant video/screenshots/hashes, record time offset on the systems, talk to witnesses, and track total man-hours and

  expenses associated with the investigation.

• Question 1405:

  Drag the items on the left to show the different types of security for the shown devices. Not all fields need to be filled. Not all items need to be used.

  Select and Place:

  

  Correct Answer:

  

  For mobile devices, at bare minimum you should have the following security measures in place: Screen lock, Strong password, Device encryption, Remote wipe/Sanitation, voice encryption, GPS tracking, Application control, Storage

  segmentation, Asset tracking as well as Device Access control.

  For servers in a data center your security should include: Fire extinguishers such as FM200 as part of fire suppression; Biometric, proximity badges, mantraps, HVAC, cable locks;

  these can all be physical security measures to control access to the server.

• Question 1406:

  A security administrator discovers that an attack has been completed against a node on the corporate network. All available logs were collected and stored.

  You must review all network logs to discover the scope of the attack, check the box of the node(s) that have been compromised and drag and drop the appropriate actions to complete the incident response on the network. The environment is

  a critical production environment; perform the LEAST disruptive actions on the network, while still performing the appropriate incident responses.

  Instructions: The web server, database server, IDS, and User PC are clickable. Check the box of the node(s) that have been compromised and drag and drop the appropriate actions to complete the incident response on the network. Not all

  actions may be used, and order is not important. If at anytime you would like to bring back the initial state of the simulation, please select the Reset button. When you have completed the simulation, please select the Done button to submit.

  

  Once the simulation is submitted, please select the Next button to continue.

  Correct Answer:

  Database server was attacked; actions should be to capture network traffic and Chain of Custody.

  (The database server logs shows the Audit Failure and Audit Success attempts)It is only logical that all the logs will be stored on the database server and the least disruption action on the network to take as a response to the incident would be

  to check the logs (since these are already collected and stored) and maintain a chain of custody of those logs.

• Question 1407:

  DRAG DROP

  Drag and drop the correct protocol to its default port.

  Select and Place:

  

  Correct Answer:

  

  FTP uses TCP port 21.

  Telnet uses port 23.

  SSH uses TCP port 22. All protocols encrypted by SSH, including SFTP, SHTTP, SCP, SExec, and slogin, also use TCP port 22. Secure Copy Protocol (SCP) is a secure filetransfer facility based on SSH and Remote Copy Protocol (RCP).

  Secure FTP (SFTP) is a secured alternative to standard File Transfer Protocol (FTP).

  SMTP uses TCP port 25.

  Port 69 is used by TFTP.

  SNMP makes use of UDP ports 161 and 162.

• Question 1408:

  The security administrator has installed a new firewall which implements an implicit DENY policy by default. Click on the firewall and configure it to allow ONLY the following communication.

  1.

  The Accounting workstation can ONLY access the web server on the public network over the default HTTPS port. The accounting workstation should not access other networks.

  2.

  The HR workstation should be restricted to communicate with the Financial server ONLY, over the default SCP port

  3.

  The Admin workstation should ONLY be able to access the servers on the secure network over the default TFTP port.

  Instructions: The firewall will process the rules in a top-down manner in order as a first match The port number must be typed in and only one port number can be entered per rule Type ANY for all ports. The original firewall configuration can

  be reset at any time by pressing the reset button. Once you have met the simulation requirements, click save and then Done to submit.

  Correct Answer:

  

  

  Section: Network Security Implicit deny is the default security stance that says if you aren't specifically granted access or privileges for a resource, you're denied access by default. Rule #1 allows the Accounting workstation to ONLY access the web server on the public network over the default HTTPS port, which is TCP port 443. Rule #2 allows the HR workstation to ONLY communicate with the Financial server over the default SCP port, which is TCP Port 22 Rule #3 and Rule #4 allow the Admin workstation to ONLY access the Financial and Purchasing servers located on the secure network over the default TFTP port, which is Port 69.

  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 data.

  Port 22 is used by both SSH and SCP with UDP.

  Port 443 is used for secure web connections
