Analysis of ESET Smart Security 6 personal firewall’s thresholds and detectio...Andrej Šimko
The main goal of this project is to observe attacks on ESET Smart Security 6’s firewall, to discover the ability to detect various attacks coming from the same LAN, and find out thresholds of triggering warning/detection relevant to those attacks.
This document discusses how the nmap scanner performs host discovery by default and explores customizing its behavior. It examines nmap's default discovery method which sends ICMP echo requests and TCP packets to target hosts and looks for responses. The document uses a DMZ network with varying firewall rulesets to demonstrate how the default method works in different scenarios. It shows that while the default method is sufficient when rules are very open, more specific rules may require customizing nmap's options to more accurately discover live hosts on the network.
Lab-5 Scanning and Enumeration Reconnaissance and inform.docxLaticiaGrissomzz
Lab-5: Scanning and Enumeration
Reconnaissance and information gathering methods were passive methods, meaning that they did not cause any alarm, alerts, and log file creation on the target systems: franklin.edu computers. In Lab-5, you will actively scan and enumerate target systems. These actions would cause some log files and probably trigger alerts if the target systems were used by a sensitive organization, such as a military or financial institution.
You will perform Lab-5 by using the Netlab environment provided by Franklin University. Netlab environment is an isolated environment with no Internet connection so that none of your actions will cause anything harmful for you or the target system. Section-1: Scan the Network Using nbtscan Tool
nbtscan is used for scanning networks to obtain NetBIOS names, file shares, and other information. It is one of the tools that come with Kali Linux. Nbtscan is a convenient tool to scan the active computers on the network quickly.
Windows machines have NetBIOS names by default. Linux/Unix computer may also have NetBIOS names if the Samba interoperability suite is installed.
Before starting scanning the network from Kali Linux, you have to learn the network address first.
1) Enter the Netlab environment
2) Open Kali Linux and enter the password (password: toor)
3) Open a terminal window
4) Type this command:
ifconfig
The IP address of your computer is 192.168.2.10, and the netmask is 255.255.255.0. That means the network address is 192.168.2.0/24. You will use this in your nbtscan.
5) Run a nbtscan by typing
nbtscan 192.168.2.0/24 to the terminal window. You will see all active computers along with IP addresses, NetBIOS names, and MAC addresses. That is an essential piece of information for a pentester and can be regarded as your initial attack surface.
Take a screenshot of the terminal window.
Section-2: Scan the Network by Using Nmap
You will perform another network scan by using a more versatile tool called Nmap. Nmap is one of the swiss knives of the pen-testers. It is a free and open-source tool and comes with Kali Linux. Nmap has many different scanning options; it can even perform vulnerability scanning in addition to network and host scanning. In this lab, you will first use Nmap's network/host scanning features, and then you will perform vulnerability scanning with Nmap.
1) Type in
nmap 192.168.2.0/24 -n -sn in the terminal window.
Take a screenshot of the terminal window.
Type in
mannmap in the terminal window to see the help page of the Nmap tool. Find why you used n and sn options.
Section-3: Perform a Port Scan Against a Host
In the previous section, you scanned the network by using Nmap. In this section, you will scan a specific host for open ports.
1) Type in
nmap 192.168.2.14 -n in the terminal window.
Take a screenshot.

3. Agenda
• Hisotry
• Introduction
• Purpose of a Graphical Frontend for Nmap- Features
• Screenshots
• Results
• Conclusion
• References
4. History:
An Nmap GUI created during the Google-sponsored Nmap
Summer of Code in 2005 and 2006. The primary author of Umit
was Adriano Monteiro Marques. When Umit was modified and
integrated into Nmap in 2007, it was renamed Zenmap.
5. Introduction
• Zenmap is the official Nmap Security Scanner GUI.
• It is a multi-platform free and open source application which aims to make
Nmap easy for beginners to use.
• It provides advanced features for experienced Nmap users.
• Frequently used scans can be saved as profiles to make them easy to run
repeatedly.
• Saved scan results can be compared with one another to see how they
differ.
• The results of recent scans are stored in a searchable database.
6. The Purpose of a Graphical Frontend for Nmap
• The nature of a frontend is that it depends on another tool to do its
job.
• Therefore the purpose of Zen-map is not to replace Nmap, but to
make Nmap more useful
7. Feature overNmap
• Interactive and graphical resultsviewing:
• In Addition to showing Nmap's normal output, Zenmap can arrange its display
to show all ports on a host or all hosts running a particular service.
• Zenmap can draw a topology map of discovered networks.
• The results of several scans may be combined together and viewed at once.
• Comparison
• Zenmap has the ability to show the differences between two scans.
• You can see what changed between the same scan run on different days, between
scans of two different hosts, between scans of the same hosts with different options,
or any othercombination.
• This allows administrators to easily track new hosts or services appearing on their
networks, or existing ones goingdown.
8. Features overNmap
• Convenience
• Zenmap keeps track of scans until deleted.That means you can run a scan, see the results,
and then decide whether to save them to a fileor delete.
• Repeatability
• Zenmap's command profiles make it easy to run the exactsame scan more than once.
• There's no need to set up a shell script to do a common scan.
• Discoverability
• Nmap has literally hundreds of options, which can be confusing for beginners.
• Zenmap's interface is designed to always show the command that will be run, whether it
comes from a profile or was built up by choosing options from a menu.
9. SCANNING
• Clicking the Zen-map icon in the desktop environment. The main window,
as shown in
• One of Zen map's goals is to make security scanning easy for beginners
and for experts
• Scan Aggregation
• Zenmap has the ability to combine the results of many Nmap
scans into one view, a feature known as scan aggregation
10. Network Inventory:
• When one scan is finished, you may start another in the same
window. When the second scan is finished, its results are merged
with those from the first. The collection of scans that make up an
aggregated view is called a network inventory.
11. Interpreting Scan Results
Scan Results Tabs:
Each scan window contains five tabs which each display different aspects of
the scan results. They are: “Nmap
Output”, “Ports / Hosts”, “Topology”, “Host Details”, and “Scans”.
The “Nmap Output” tab
The “Nmap Output” tab is displayed by default when a scan is run. It shows
the familiar Nmap terminal output .
12. The “Ports / Hosts” tab
The “Ports / Hosts” tab's display a host or a service is currently selected. When a host is selected, it shows all the interesting
ports on that host, along with version information when available.
13. The “Topology” tab
The “Topology” tab is an interactive view of the connections between hosts in a network.
14. The “Host Details” tab
The “Host Details” tab breaks all the information about a single host into a hierarchical display. Shown are the host's
names and addresses, its state (up or down), and the number and status of scanned ports
15. The “Scans” tab
The “Scans” tab shows all the scans that are aggregated to make up the network inventory. From this tab you can add
scans (from a file or directory) and remove scans.
While a scan is executing and not yet complete, its status is “Running”. You may cancel a running scan by clicking
the “Cancel Scan” button.
16. Intense scan:
Command: nmap -T4 -A -v <target>
Should be reasonable quick, scan the most common TCP ports. It will make an effort in determining the OS
type and what services and their versions are running.
This comes from having a pretty fast timing template (-T4) and for using the -A option which will try determine
services, versions and OS. With the verbose output (-v) it will also give us a lot of feedback as Nmap makes
progress in the scan.
Intense scan plus UDP:
Command: nmap -sS -sU -T4 -A -v <target>
Same as the regular Intense scan, just that we will also scan UDP ports (-sU).
The -sS option is telling Nmap that it should also scan TCP ports using SYN packets. Because this scan includes
UDP ports this explicit definition of -sS is necessary.
17. Intense scan, all TCP ports:
Command: nmap -p 1-65535 -T4 -A -v <target>
Leave no TCP ports unchecked.
Normally Nmap scans a list of 1000 most common protocols, but instead we will in this example scan
everything from port 1 to 65535 (max). The 1000 most common protocols listing can be found in the file called
nmap-services.
Intense scan, no ping
Command: nmap -T4 -A -v -Pn <target>
Just like the other intense scans, however this will assume the host is up. Usefull if the target is blocking ping
request and you already know the target is up.
Ping scan;
Command: nmap -sn <target>
Do only a ping only on the target, no port scan.
Quick scan:
Command: nmap -T4 -F <target>
Scan faster than the intense scan by limiting the number of TCP ports scanned to only the top 100 most
common TCP ports
18. Quick scan plus:
Command: nmap -sV -T4 -O -F –version-light <target>
Add a little bit of version and OS detection and you got the Quick scan plus.
Quick traceroute:
Command: nmap -sn –traceroute <target>
Use this option when you need to determine hosts and routers in a network scan. It will traceroute and ping all hosts
defined in the target.
Regular scan:
Command: nmap <target>
Default everything. This means it will issue a TCP SYN scan for the most common 1000 TCP ports, using ICMP Echo request
(ping) for host detection.
19. The options:
-T4 This is an option for timing template. Numbers range from 0-5 where 5 is the fastest and 0 is the slowest.
-A This options makes Nmap make an effort in identifying the target OS, services and the versions. It also does
traceroute and applies NSE scripts to detect additional information.
-v Increased verbosity. This will give your extra information in the data outputted by Nmap.
-sS Perform a TCP SYN connect scan. This just means that Nmap will send a TCP SYN packet just like any normal
application would do.
-sU Perform an UDP scan. Because UDP is unreliable it is not as easy to determine if ports are open as it is with TCP.
The UDP scan sends an UDP packet with an empty header to the target port. If the port is closed the OS should reply
with an ICMP port unreachable error, however if the port is open it does not necessarily mean that the service will
reply with anything.
-sN TCP Null scan. This option sends TCP packets with none of the TCP flags set in the packet. If the scan is returned a
RST packet it means the port is closed, however if nothing is returned it is either filtered or open
-sV Actively probe open ports to try determine what service and version they are running. When running this scan
against my webserver it resulted in 14 packets being transmitted between client and server, in contrast to just 2
packets as with a regular SYN scan.
20. The options:
-Pn Assume the host is up thus skipping the host discovery phase.
-sn Only send ping packet to the target, no port scanning. This is usefull if you need to determine what hosts
are in the vicinity, but do not want to scan them yet. Do not mistake this for the TCP Null scan (-sN); Nmap is
case sensitive.
-PY Very much like a TCP SYN scan, this just utilizes the SCTP (Stream Control Transmission Protocol) instead.
-PS Also used for host discovery. This option simply relies on a port (default 80) to reply to an empty SYN
packet, as is with default TCP behaviour. Simple is often good.
21. 1.
Basic Nmap Scan against IP or host
nmap 1.1.1.1
Now, if you want to scan a hostname, simply replace the IP for the host, as you see below:
nmap cloudflare.com
These kinds of basic scans are perfect for your first steps when starting with Nmap.
2.
Scan specific ports or scan entire port ranges on a local or remote server
nmap -p 1-65535 localhost
In this example, we scanned all 65535 ports for our localhost computer.
31. Conclusion
• Network monitoring is a crucial activity to prevent any network from
intrusions.
• Scanning of network issues will make us aware of the potential
network attacks and helps us to prepare a prevention plan to avoid
them.
• Zenmap provides a simple and easy interface for novice users.
• Zenmap also provides interfaces for viewing multiple scan results at
once.
