Auditor provides two tools that are perfect for this. 9.ĭue to its ability to determine associated client information, Kismet is the perfect wireless enumeration tool for penetration testers.ĭetermining the encryption type is one of the best ways to ascertain the vulnerability status of a wireless network. There are two WLAN scanning tools included with Auditor. Just like on any penetration test, Internet search engine queries and USENET newsgroup searches are perfect for intelligence gathering. GPSMap is a tool, included with Kismet, that is perfect for determining the wireless footprint of your target organization.
These are ways of not only setting up and running the scans in your environment but also for interpreting the feedback. Finally, the chapter will close with information related to advanced Nmap scanning techniques. We’ll dig into a section devoted to securing and optimizing. Ten short Internet-years have passed since the release of Nmap and we’ll discuss how Nmap has evolved and where it continues to help us with current enterprise scanning needs. We’ll properly introduce Nmap in this chapter, talking a bit about its history and some of the scanning ideas that the author, Fyodor, integrated into that first release. However, the neat thing about Nmap is both the ease with which it can be installed and utilized, as well as how advanced you can get with the tool as you become more familiar with it and learn more about how it can meet your own scanning needs. Having a background in IT audit, information security or even system administration will definitely help as you start to learn about this tool. Now we’re going to start our deep dive into one of the most popular network scanning tools of all time, Nmap, which can be found at. In the first chapter, we learned about network scanning at a high level and discussed some of the different technologies and methodologies available to perform scans.
A list of some of the scanning and enumeration tools targeted at VoIP can be found in the VoIP Scanning and Enumeration Tools section of the VoIPSA VoIP Security Tools List available at Scanning and Enumeration Tools.Īngela Orebaugh, Becky Pinkard, in Nmap in the Enterprise, 2008 Introduction There are, of course, tools that automate this process by scanning an IP address range, identifying the device found at each target IP address and then attempting to compromise that device. Once the attacker has identified UC endpoints, he or she can then move on to attacking each endpoint with specific attacks outlined in the next sections. There are also tools that are specifically focused at finding SIP endpoints such as the svmap tool that is a part of the SIPVicious tool suite. Other variations of nmap commands could further probe and identify, for instance, other services running on the endpoints. You'll notice that the nmap identified each of the examples as, in this case, Mitel and Polycom IP phones. For example, if your UC system is SIP-based, you can scan the network for any device with services listening on port 5060, the default SIP port, as shown in this command sample:īash-3.2# nmap -p 5060 -open 172.20.12.0/24 If an attacker has access to your internal network, perhaps through an unsecured Wi-Fi wireless network or a compromised device on the network edge, he or she can use a network-scanning tool such as “nmap” F to scan your network. When the hacker group has an overview of those, they can commence with weaponization and delivery of the first attacks while still scanning the other services.ĭan York, in Seven Deadliest Unified Communications Attacks, 2010 Enumerating Endpoints It is recommended that the hacker group configures their network scanning tools in such a way that they first scan the most important services, for example, the services that are known to contain security issues. Networks consisting of 16 million IP addresses, with every IP address potentially having more than 100,000 network services available, are not unusual. Often the guerilla band will find themselves in the position where they have to scan a large network in a short amount of time. The challenge in using network scanning tools is to decrease the scanning time. These tools do nothing more than enumerate systems and services, and in doing so, they can quickly give an overview of connected systems, especially when the hacker group encounters a new, unknown network. To perform external and internal reconnaissance of available infrastructure components, network scanning tools can be used. van Haaster, in Cyber Guerilla, 2016 Network scanning tools
