Automating the User Interface

Unfortunately, not every Mac app has scripting support, and those that do may not always have scripting support for every task you want to automate. You can often work around such limitations, however, by writing a user interface script, commonly called a UI or GUI script. A user interface script simulates user interaction, such as mouse clicks and keystrokes, allowing the script to select menu items, push buttons, enter text into text fields, and more.

Enabling User Interface Scripting

User interface scripting relies upon the OS X accessibility frameworks that provide alternative methods of querying and controlling the interfaces of apps and the system. By default, accessibility control of apps is disabled. For security and privacy reasons, the user must manually enable it on an app-by-app (including script apps) basis.

1. Launch System Preferences and click Security & Privacy.

2. Click Accessibility. https://softmommy.mystrikingly.com/blog/the-fall-itch-sofia-kroob-mac-os.

3. Choose an app and click Open.

When running an app that requires accessibility control for the first time, the system prompts you to enable it. See Figure 37-1.

Attempting to run an app that has not been given permission to use accessibility features results in an error. Charlies adventures in the heart kingdom mac os. See Figure 37-2.

Note

To run a user interface script in Script Editor, you must enable accessibility for Script Editor.

Admin credentials are required to perform enable user interface scripting.

Targeting an App

User interface scripting terminology is found in the Processes Suite of the System Events scripting dictionary. This suite includes terminology for interacting with most types of user interface elements, including windows, buttons, checkboxes, menus, radio buttons, text fields, and more. In System Events, the process class represents a running app. Listing 37-1 shows how to target an app using this class.

APPLESCRIPT

1. tell application 'System Events'
2. tell process 'Safari'
3. -- Perform user interface scripting tasks
4. end tell
5. end tell

To control the user interface of an app, you must first inspect the app and determine its element hierarchy. This can be done by querying the app. For example, Listing 37-2 asks Safari for a list of menus in the menu bar.

APPLESCRIPT

1. tell application 'System Events'
2. tell process 'Safari'
3. name of every menu of menu bar 1
4. end tell
5. end tell
6. --> Result: {'Apple', 'Safari', 'File', 'Edit', 'View', 'History', 'Bookmarks', 'Develop', 'Window', 'Help'}

Accessibility Inspector (Figure 37-3) makes it even easier to identify user interface element information. This app is included with Xcode. To use it, open Xcode and select Xcode > Open Developer Tool > Accessibility Inspector.

Once you know how an element fits into an interface, you target it within that hierarchy. For example, button X of window Y of process Z.

Clicking a Button

Use the click command to click a button. Listing 37-3 clicks a button in the Safari toolbar to toggle the sidebar between open and closed.

APPLESCRIPT

1. tell application 'System Events'
2. tell process 'Safari'
3. tell toolbar of window 1
4. click (first button where its accessibility description = 'Sidebar')
5. end tell
6. end tell
7. end tell
8. --> Result: {button 1 of toolbar 1 of window 'AppleScript: Graphic User Interface (GUI) Scripting' of application process 'Safari' of application 'System Events'}

Choosing a Menu Item

Menu items can have a fairly deep hierarchy within the interface of an app. A menu item generally resides within a menu, which resides within a menu bar. In scripting, they must be addressed as such. Listing 37-4 selects the Pin Tab menu item in the Window menu of Safari.

APPLESCRIPT

1. tell application 'System Events'
2. tell process 'Safari'
3. set frontmost to true
4. click menu item 'Pin Tab' of menu 'Window' of menu bar 1
5. end tell
6. end tell
7. --> Result: menu item 'Pin Tab' of menu 'Window' of menu bar item 'Window' of menu bar 1 of application process 'Safari' of application 'System Events'

Note

Scripting the user interface of an app can be tedious and repetitious. To streamline the process, consider creating handlers to perform common functions. For example, Listing 37-5 shows a handler that can be used to choose any menu item of any menu in any running app.

APPLESCRIPT

1. on chooseMenuItem(theAppName, theMenuName, theMenuItemName)
2. try
3. -- Bring the target app to the front
4. tell application theAppName
5. activate
6. end tell
7. -- Target the app
8. tell application 'System Events'
9. tell process theAppName
10. -- Target the menu bar
11. tell menu bar 1
12. -- Target the menu by name
13. tell menu bar item theMenuName
14. tell menu theMenuName
15. -- Click the menu item
16. click menu item theMenuItemName
17. end tell
18. end tell
19. end tell
20. end tell
21. end tell
22. return true
23. on error
24. return false
25. end try
26. end chooseMenuItem

Listing 37-6 calls the handler in Listing 37-5 to select the Pin Tab menu item in the Window menu of Safari.

APPLESCRIPT

Choosing a Submenu Item

Some menus contain other menus. In these cases, it may be necessary to select a menu item in a submenu of a menu. Listing 37-7 demonstrates how this would be done by selecting a submenu item in Safari.

APPLESCRIPT

1. tell application 'System Events'
2. tell process 'Safari'
3. set frontmost to true
4. click menu item 'Email This Page' of menu of menu item 'Share' of menu 'File' of menu bar 1
5. end tell
6. end tell
7. --> Result: {menu item 'Email This Page' of menu 'Share' of menu item 'Share' of menu 'File' of menu bar item 'File' of menu bar 1 of application process 'Safari' of application 'System Events'}

Nmap is a network mapper that has emerged as one of the most popular, free network discovery tools on the market. Nmap is now one of the core tools used by network administrators to map their networks. The program can be used to find live hosts on a network, perform port scanning, ping sweeps, OS detection, and version detection.

A number of recent cyberattacks have re-focused attention on the type of network auditing that Nmap provides. Analysts have pointed out that the recent Capital One hack, for instance, could have been detected sooner if system administrators had been monitoring connected devices. In this guide, we’ll look at what Nmap is, what it can do, and explain how to use the most common commands.

Get the Free Pen Testing Active Directory Environments EBook

Ideally, Nmap should be used as part of an integrated Data Security Platform. Once Nmap has been used to map a network, a platform such as Varonis’ Datadvantage can then be used to implement advanced access control.

What is Nmap?

At its core, Nmap is a network scanning tool that uses IP packets to identify all the devices connected to a network and to provide information on the services and operating systems they are running.

The program is most commonly used via a command-line interface (though GUI front-ends are also available) and is available for many different operating systems such as Linux, Free BSD, and Gentoo. Its popularity has also been bolstered by an active and enthusiastic user support community.

Nmap was developed for enterprise-scale networks and can scan through thousands of connected devices. However, in recent years Nmap is being increasingly used by smaller companies. The rise of the IoT, in particular, now means that the networks used by these companies have become more complex and therefore harder to secure.

This means that Nmap is now used in many website monitoring tools to audit the traffic between web servers and IoT devices. The recent emergence of IoT botnets, like Mirai, has also stimulated interest in Nmap, not least because of its ability to interrogate devices connected via the UPnP protocol and to highlight any devices that may be malicious.

What Does Nmap Do?

At a practical level, Nmap is used to provide detailed, real-time information on your networks, and on the devices connected to them.

The primary uses of Nmap can be broken into three core processes. First, the program gives you detailed information on every IP active on your networks, and each IP can then be scanned. This allows administrators to check whether an IP is being used by a legitimate service, or by an external attacker.

Secondly, Nmap provides information on your network as a whole. It can be used to provide a list of live hosts and open ports, as well as identifying the OS of every connected device. This makes it a valuable tool in ongoing system monitoring, as well as a critical part of pentesting. Nmap can be used alongside the Metasploit framework, for instance, to probe and then repair network vulnerabilities.

Thirdly, Nmap has also become a valuable tool for users looking to protect personal and business websites. Using Nmap to scan your own web server, particularly if you are hosting your website from home, is essentially simulating the process that a hacker would use to attack your site. “Attacking” your own site in this way is a powerful way of identifying security vulnerabilities.

How To Use Nmap

Nmap is straightforward to use, and most of the tools it provides are familiar to system admins from other programs. The advantage of Nmap is that it brings a wide range of these tools into one program, rather than forcing you to skip between separate and discrete network monitoring tools.

In order to use Nmap, you need to be familiar with command-line interfaces. Most advanced users are able to write scripts to automate common tasks, but this is not necessary for basic network monitoring.

How To Install Nmap

The process for installing Nmap is easy but varies according to your operating system. The Windows, Mac, and Linux versions of the program can be downloaded here.

• For Windows, Nmap comes with a custom installer (namp<version>setup.exe). Download and run this installer, and it automatically configures Nmap on your system.
• On Mac, Nmap also comes with a dedicated installer. Run the Nmap-<version>mpkg file to start this installer. On some recent versions of macOS, you might see a warning that Nmap is an “unidentified developer”, but you can ignore this warning.
• Linux users can either compile Nmap from source or use their chosen package manager. To use apt, for instance, you can run Nmap –version to check if Nmap is installed, and sudo apt-get install Nmap to install it.

Nmap Tutorial and Examples

Once you’ve installed Nmap, the best way of learning how to use it is to perform some basic network scans.

How To Run a Ping Scan

One of the most basic functions of Nmap is to identify active hosts on your network. Nmap does this by using a ping scan. This identifies all of the IP addresses that are currently online without sending any packers to these hosts.

To run a ping scan, run the following command:

This command then returns a list of hosts on your network and the total number of assigned IP addresses. If you spot any hosts or IP addresses on this list that you cannot account for, you can then run further commands (see below) to investigate them further.

How To Run A Host Scan

A more powerful way to scan your networks is to use Nmap to perform a host scan. Unlike a ping scan, a host scan actively sends ARP request packets to all the hosts connected to your network. Each host then responds to this packet with another ARP packet containing its status and MAC address.

To run a host scan, use the following command:

Famous fables: read learn and play mac os. This returns information on every host, their latency, their MAC address, and also any description associated with this address. This can be a powerful way of spotting suspicious hosts connected to your network.

If you see anything unusual in this list, you can then run a DNS query on a specific host, by using:

This returns a list of names associated with the scanned IP. This description provides information on what the IP is actually for.

How To Use Nmap in Kali Linux

Using Nmap in Kali Linux can be done in an identical way to running the program on any other flavor of Linux.

That said, there are advantages to using Kali when running Nmap scans. Most modern distros of Kali now come with a fully-features Nmap suite, which includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).

Nmap Commands

Most of the common functions of Nmap can be executed using a single command, and the program also uses a number of ‘shortcut’ commands that can be used to automate common tasks.

Here is a quick run-down:

1. Ping Scanning

As mentioned above, a ping scan returns information on every active IP on your network. You can execute a ping scan using this command:

2. Port Scanning

There are several ways to execute port scanning using Nmap. The most commonly used are these:

The major differences between these types of scans are whether they cover TCP or UDP ports and whether they execute a TCP connection. Here are the basic differences:

• The most basic of these scans is the sS TCP SYN scan, and this gives most users all the information they need. It scans thousands of ports per second, and because it doesn’t complete a TCP connection it does not arouse suspicion.
• The main alternative to this type of scan is the TCP Connect scan, which actively queries each host, and requests a response. This type of scan takes longer than a SYN scan, but can return more reliable information.
• The UDP scan works in a similar way to the TCP connect scan but uses UDP packets to scan DNS, SNMP, and DHCP ports. These are the ports most frequently targeted by hackers, and so this type of scan is a useful tool for checking for vulnerabilities.
• The SCTP INIT scan covers a different set of services: SS7 and SIGTRAN. This type of scan can also be used to avoid suspicion when scanning an external network because it doesn’t complete the full SCTP process.
• The TOP NULL scan is also a very crafty scanning technique. It uses a loophole in the TCP system that can reveal the status of ports without directly querying them, which means that you can see their status even where they are protected by a firewall.

3. Host Scanning

https://lastlex969.weebly.com/blog/countless-ceilings-mac-os. Host scanning returns more detailed information on a particular host or a range of IP addresses. As mentioned above, you can perform a host scan using the following command:

4. OS Scanning

OS scanning is one of the most powerful features of Nmap. When using this type of scan, Nmap sends TCP and UDP packets to a particular port, and then analyze its response. It compares this response to a database of 2600 operating systems, and return information on the OS (and version) of a host.

To run an OS scan, use the following command:

5. Scan The Most Popular Ports

If you are running Nmap on a home server, this command is very useful. It automatically scans a number of the most ‘popular’ ports for a host. You can run this command using:

Tey Al Tool Mac Os Catalina

Replace the “20” with the number of ports to scan, and Nmap quickly scans that many ports. It returns a concise output that details the status of the most common ports, and this lets you quickly see whether you have any unnecessarily open ports.

6. Output to a File

Tey Al Tool Mac Os 11

If you want to output the results of your Nmap scans to a file, you can add an extension to your commands to do that. Simply add:

To your command to output the results to a text file, or:

To output to an XML.

7. Disable DNS Name Resolution

Finally, you can speed up your Nmap scans by using the -n parameter to disable reverse DNS resolution. This can be extremely useful if you want to scan a large network. For example, to turn off DNS resolution for the basic ping scan mentioned above, add -n:

Nmap FAQ

The commands above cover most of the basic functionality of Nmap. You might still have some questions though, so let’s run through the most common ones.

Q: What Are Some Nmap Alternatives?

There are some alternatives to Nmap, but most of them are focused on providing specific, niche functionality that the average system administrator does need frequently. MASSCAN, for instance, is much faster than Nmap but provides less detail. Umit, by contrast, allows you to run several scans at once.

In reality, however, Nmap provides all the functionality and speed that the average user requires, especially when used alongside other similarly popular tools like NetCat (which can be used to manage and control network traffic) and ZenMap (which provides a GUI for Nmap)

Q: How Does Nmap Work?

Nmap builds on previous network auditing tools to provide quick, detailed scans of network traffic. It works by using IP packets to identify the hosts and IPs active on a network and then analyze these packets to provide information on each host and IP, as well as the operating systems they are running.

Q: Is Nmap Legal?

Yes. If used properly, Nmap helps protect your network from hackers, because it allows you to quickly spot any security vulnerabilities in your systems.

Whether port scanning on external servers is legal is another issue. The legislation in this area is complex and varies by territory. Using Nmap to scan external ports can lead to you being banned by your ISP, so make sure you research the legal implications of using the program before you start using it more widely.

The Bottom Line

Taking the time to learn Nmap can dramatically increase the security of your networks because the program offers a quick, efficient way of auditing your systems. Even the basic features offered by the program – such as the ability to perform port scanning – quickly reveal any suspicious devices that are active on your network.
