Timing is an element of port-scanning that can catch one unaware. If scans are taking too long to complete or obvious ports are missing from the scan, various time parameters may need to be adjusted.
Which one of the following scanned timing options in NMAP’s scan is useful across slow WAN links or to hide the scan?
Which one of the following scans starts, but does not complete the TCP handshake sequence for each port selected, and it works well for direct scanning and often works well through firewalls?
Transmission control protocol accepts data from a data stream, divides it into chunks, and adds a TCP header creating a TCP segment. The TCP header is the first 24 bytes of a TCP segment that contains the parameters and state of an end-to-end TCP socket. It is used to track the state of communication between two TCP endpoints.
For a connection to be established or initialized, the two hosts must synchronize. The synchronization requires each side to send its own initial sequence number and to receive a confirmation of exchange in an acknowledgment (ACK) from the other side
The below diagram shows the TCP Header format:
Michael works for Kimball Construction Company as senior security analyst. As part of yearly security audit, Michael scans his network for vulnerabilities. Using Nmap, Michael conducts XMAS scan and most of the ports scanned do not give a response. In what state are these ports?
Which of the following documents helps in creating a confidential relationship between the pen tester and client to protect critical and confidential information or trade secrets?
The first phase of the penetration testing plan is to develop the scope of the project in consultation with the client. Pen testing test components depend on the client’s operating environment, threat perception, security and compliance requirements, ROE, and budget.
Various components need to be considered for testing while developing the scope of the project.
Which of the following is NOT a pen testing component to be tested?
Black-box testing is a method of software testing that examines the functionality of an application (e.g. what the software does) without peering into its internal structures or workings. Black-box testing is used to detect issues in SQL statements and to detect SQL injection vulnerabilities.
Most commonly, SQL injection vulnerabilities are a result of coding vulnerabilities during the Implementation/Development phase and will likely require code changes. Pen testers need to perform this testing during the development phase to find and fix the SQL injection vulnerability.
What can a pen tester do to detect input sanitization issues?
Vulnerability assessment is an examination of the ability of a system or application, including the current security procedures and controls, to withstand assault.
What does a vulnerability assessment identify?
What is a good security method to prevent unauthorized users from "tailgating"?
What are placeholders (or markers) in an HTML document that the web server will dynamically replace with data just before sending the requested documents to a browser?
You are the security analyst working for a private company out of France. Your current assignment is to obtain credit card information from a Swiss bank owned by that company. After initial reconnaissance, you discover that the bank security defenses are very strong and would take too long to penetrate. You decide to get the information by monitoring the traffic between the bank and one of its subsidiaries in London.
After monitoring some of the traffic, you see a lot of FTP packets traveling back and forth. You want to sniff the traffic and extract usernames and passwords. What tool could you use to get this information?
A framework for security analysis is composed of a set of instructions, assumptions, and limitations to analyze and solve security concerns and develop threat free applications.
Which of the following frameworks helps an organization in the evaluation of the company’s information security with that of the industrial standards?
A firewall protects networked computers from intentional hostile intrusion that could compromise confidentiality or result in data corruption or denial of service. It examines all traffic routed between the two networks to see if it meets certain criteria. If it does, it is routed between the networks, otherwise it is stopped.
Why is an appliance-based firewall is more secure than those implemented on top of the commercial operating system (Software based)?
Larry is an IT consultant who works for corporations and government agencies. Larry plans on shutting down the city's network using BGP devices and Zombies? What type of Penetration Testing is Larry planning to carry out?
Rules of Engagement (ROE) document provides certain rights and restriction to the test team for performing the test and helps testers to overcome legal, federal, and policy-related restrictions to use different penetration testing tools and techniques.
What is the last step in preparing a Rules of Engagement (ROE) document?

What will this search produce?
Simon is a former employee of Trinitron XML Inc. He feels he was wrongly terminated and wants to hack into his former company's network. Since Simon remembers some of the server names, he attempts to run the AXFR and IXFR commands using DIG.
What is Simon trying to accomplish here?
Harold wants to set up a firewall on his network but is not sure which one would be the most appropriate. He knows he needs to allow FTP traffic to one of the servers on his network, but he wants to only allow FTP-PUT.
Which firewall would be most appropriate for Harold?
Firewall is an IP packet filter that enforces the filtering and security policies to the flowing network traffic. Using firewalls in IPv6 is still the best way of protection from low level attacks at the network and transport layers.
Which one of the following cannot handle routing protocols properly?
HTTP protocol specifies that arbitrary binary characters can be passed within the URL by using %xx notation, where 'xx' is the
