DMZ is a network designed to give the public access to the specific internal resources and you might want to do the same thing for guests visiting organizations without compromising the integrity of the internal resources. In general, attacks on the wireless networks fall into four basic categories.
Identify the attacks that fall under Passive attacks category.
SQL injection attack consists of insertion or "injection" of either a partial or complete SQL query via the data input or transmitted from the client (browser) to the web application. A successful SQL injection attack can:
i) Read sensitive data from the database
iii) Modify database data (insert/update/delete)
iii) Execute administration operations on the database (such as shutdown the DBMS)
iV) Recover the content of a given file existing on the DBMS file system or write files into the file system
v) Issue commands to the operating system
Pen tester needs to perform various tests to detect SQL injection vulnerability. He has to make a list of all input fields whose values could be used in crafting a SQL query, including the hidden fields of POST requests and then test them separately, trying to interfere with the query and to generate an error.
In which of the following tests is the source code of the application tested in a non-runtime environment to detect the SQL injection vulnerabilities?
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.

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?
Wireless communication allows networks to extend to places that might otherwise go untouched by the wired networks. When most people say ‘Wireless’ these days, they are referring to one of the 802.11 standards. There are three main 802.11 standards: B, A, and G.
Which one of the following 802.11 types uses DSSS Modulation, splitting the 2.4ghz band into channels?
Internet Control Message Protocol (ICMP) messages occur in many situations, such as whenever a datagram cannot reach the destination or the gateway does not have the buffering capacity to forward a datagram.
Each ICMP message contains three fields: type, code, and checksum. Different types of Internet Control Message Protocols (ICMPs) are identified by a TYPE field.
If the destination is not reachable, which one of the following are generated?
Which of the following is NOT related to the Internal Security Assessment penetration testing strategy?

In the process of hacking a web application, attackers manipulate the HTTP requests to subvert the application authorization schemes by modifying input fields that relate to the user ID, username, access group, cost, file names, file identifiers, etc.
They first access the web application using a low privileged account and then escalate privileges to access protected resources. What attack has been carried out?
SQL injection attacks are becoming significantly more popular amongst hackers and there has been an estimated 69 percent increase of this attack type.
This exploit is used to great effect by the hacking community since it is the primary way to steal sensitive data from web applications. It takes advantage of non-validated input vulnerabilities to pass SQL commands through a web application for execution by a back-end database.
The below diagram shows how attackers launched SQL injection attacks on web applications.
Which of the following can the attacker use to launch an SQL injection attack?
External penetration testing is a traditional approach to penetration testing and is more focused on the servers, infrastructure and the underlying software comprising the target. It involves a comprehensive analysis of publicly available information about the target, such as Web servers, Mail servers, Firewalls, and Routers.

Variables are used to define parameters for detection, specifically those of your local network and/or specific servers or ports for inclusion or exclusion in rules. These are simple substitution variables set with the var keyword.
Which one of the following operator is used to define meta-variables?
ARP spoofing is a technique whereby an attacker sends fake ("spoofed") Address Resolution Protocol (ARP) messages onto a Local Area Network. Generally, the aim is to associate the attacker's MAC address with the IP address of another host (such as the default gateway), causing any traffic meant for that IP address to be sent to the attacker instead.
ARP spoofing attack is used as an opening for other attacks.
What type of attack would you launch after successfully deploying ARP spoofing?
Many security and compliance projects begin with a simple idea: assess the organization's risk, vulnerabilities, and breaches. Implementing an IT security risk assessment is critical to the overall security posture of any organization.

Which one of the following functions is used as a programspecific signal and the handler for this calls the DropStats() function to output the current Snort statistics?
After passively scanning the network of Department of Defense (DoD), you switch over to active scanning to identify live hosts on their network. DoD is a large organization and should respond to any number of scans. You start an ICMP ping sweep by sending an IP packet to the broadcast address.
Only five hosts responds to your ICMP pings; definitely not the number of hosts you were expecting. Why did this ping sweep only produce a few responses?
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:
You are assisting a Department of Defense contract company to become compliant with the stringent security policies set by the DoD. One such strict rule is that firewalls must only allow incoming connections that were first initiated by internal computers.
