These test scripts, or in simple terms, a short program written either using functional GUI test tools or in programming languages are focused on testing functionalities of a software system. Moreover, this testing can either be executed manually or using an automated pattern. Also, since we live in an era where machines are taking over manual labour, automation seems like the better option. A simplified process of developing a program to test software, automation testing reduces human effort.

An automation testing program or script, written by developer uses test data. The data is automatically entered to generate output.

This further creates an analysis of the entire data, measuring the efficiency of the program. As the name itself implies, automating specific tasks can profoundly reduce the effort required in addition to the investment of time and money. Automating a process means, no more human interaction for long hours to verify the working.

It slashes the scope of human error, increases efficiency, and the scope of work. Network traffic, in simple terminology, is the amount of data travelling through a network. Precisely put, the network traffic includes the entire exchange of data between a browser and server. For instance, when opening a website, downloading images, text and any other templates are included in the network traffic. For any web, application efficiency is the most critical factor. Also, one would like to keep a check on network usage and any possible data drain.

Analyzing the traffics gives us such insights, making it easier to find solutions. The process of inspecting traffic is simple.

Once all the requests have been triggered on a web page, it is easy to collect the responses which in turn help the user find out the shortcomings if any. This will help measure all the functioning and create reports to analyze the statistics.

Whenever traffic monitoring is done, several parameters need special attention to get maximum accuracy. Capturing network traffic requires specialized tools that monitor the network in which it is deployed. These tools aggregate, segregate, apply user-provided rules and visualize various aspects related to network traffic.

Here are some of the most popular tools used for this purpose. Wireshark is one of the most widely used network monitoring tools today. A free and an open source tool, Wireshark equips you with a packet analyzer that can go to microscopic levels of networking monitoring. It has some powerful features such as a feature-rich GUI for monitoring, a pluggable interface to monitor a new type of protocol, live data connection to ports, multi-protocol scalable dissectors, and more. You can learn more about Wireshark through their official video guides.

If you are on a windows machine, you can use the inbuilt network monitoring tool to capture and analyze your network traffic. Apart from the broader capabilities of capturing traffic through the adapters or even the subnets, this tool can be used for much finer operations. When the goal of traffic monitoring is to have an eye on the health of the network, it becomes imperative to monitor each device state and the communication that occurs within the network.

For such purposes, this multi-OS network monitoring tool Observium performs extremely well.

Script or Program Monitor – network monitoring using scripting

Observium will help you to improve visibility within your network. With features such as device auto-discovery, health checks of existing devices and reporting features makes it one of the most sought-after tools for discovery and status check use cases. Now that you have the required parameters and the resources to fetch the data and get results, traffic monitoring seems simple, right?

Well, it might. However, would it be as good as an automated process? With an automated traffic monitoring model, the automation script enables sample data to be pitched in to generate situation based results. Moreover, the use of automation scripts and tools can reduce the expenses involved as well as manual effort.

An automated script not only reduces cost but also cuts down on the scope of human error.The broadcast packet monitor script developed with Python and Tsharkanalyzes the number of broadcast packets on the network within a certain period of time. This can be used for analyzing network traffic congestion due to broadcast issues. The tool writes all broadcast packets received during the specified time to an output file. The execution and output of the code is shown below. The script is developed using Python and tshark.

The tool writes the IP address of the initiators of the ping requests by capturing their source IP addresses and writing it to an output file.

The source code is shown below. The code captures all packets which has the destination address of To demonstrate the functionality of the code, the system on which the script is installed The HTTP Connection monitoring script developed with Python and netsat, displays the http connections on a Windows system and prints it to the output.

The following scripts are developed using Pythonthsark and netstat. Setup Python and Tshark on the system on which monitoring has to be performed. Python source code.It is used to run an external program or script and interpret its return code and printed output as data to check and raise alert when necessary.

Since it is possible to run almost any type of program available to Windows users, this kind of monitor is a universal tool to provide data when built-in monitors cannot be used. Since IPHost Network Monitor expects known return code and printed output values, such a program script usually can be created by a sysadmin to get data otherwise unavailable through built-in tools.

As in all the cases, the lack of monitoring, as well as incorrect usage of such a monitor may result in unexpected service failure, data loss etc. Creation of Program or Script Monitor is a simple process. Locate program executable or script file to run. Provide required command-line parameters if anydo not forget to quote parameters values if necessary.

Finally, provide, if required, credentials domain name, user and password to run the program as default is to use credentials IPHost Network Monitor uses to run. Optionally, a value can be used to divide the result, if necessary. If a program executes as expected, it should return zero as return code and print an integer to the standard output. The printed value is used to calculate performance state. In case of an error, program returns non-zero return value and prints error message.

Since running external programs can be inefficient and lead to undesired consequences such as memory leaks, other monitors types should be considered if possible, such as WMI monitor.

Developers can use Program or Script Monitor to check whether the development process building a program has passed as expected e. System administrators can check Smart monitors values in this way. It is recommended to contact IPHost Network Monitors developers and propose a monitor type missing in the distributed version. Consider setting those lighter monitors as dependencies.

Monitoring Features.In the 12 years since Microsoft released PowerShell, it has become the de facto tool to dependably administer servers. In August ofit was made open-source and cross-platform with the introduction of PowerShell Core.

Microsoft also purchased Github in Junemaking it the home of the increasing catalog of PowerShell scripts. You can use some of the scripts below to add security. Some let you review the security status of a network. Others allow you to see what an attacker would do to a system. These 10 PowerShell scripts should not be considered standalone, but as a much larger collection of tools needed to manage workstations and servers.

Even attackers acknowledge that PowerShell is key to controlling workstations making PowerShell a key way that attackers pivot and do lateral movement on a network once they gain access. As always, remember that if you have not run PowerShell scripts on a system, you have to adjust the settings to allow them to run. If Execution-Policy is not already set to allow running scripts, then manually set it as below and then use the readiness script: Set-ExecutionPolicy Unrestricted, and then adjust the Execution policy to the setting desired in your firm.

For any edge based system or public-facing web server, I strongly recommend installing and configuring Sysmon to better track future attacks. You should anticipate that you will be attacked and thus plan accordingly.

However, configuring each system independently can be a hassle. You can then analyze them and then identify malicious or anomalous activity and understand how intruders and malware operate on the network. As noted in the bloga sample event that can be tracked using the ProcessAccess filter for Local Security Authority Subsystem Service LSASS to detect if a malicious process is trying to extract credentials from memory.

One way that attackers can exploit Office is to obtain access to the credentials of an Office user and then set up a silent rule in Outlook to forward financial or attack emails to the attacker. Thus, you should determine if you can block all forwarding rules proactively. However, you can use individual PowerShell commands to review if there is a forwarding set up and disable it accordingly.

One key way to reduce lateral attacks in a network is to remove common local administrator passwords. A longstanding script you can use is the Remove-LocalAdmins Masive scriptwhich is still a key tool to look at all the computers specified in a text file for all the users listed in another file, and then remove those users.

The Local Administrator Password LAPS toolkit allows you to set random local administrator passwords in a domain to ensure that pass-the-hash attacks do not occur.

The new kid on the block is the cloud, and PowerShell brings new meaning to both secure and understand how attackers use PowerShell in attacks. MicroBurst is a collection of PowerShell scripts that support Azure Services discovery, weak configuration auditing, and post exploitation actions such as credential dumping. It is intended to be used during penetration tests where Azure is in use.

In a YouTube video from an October session at Derbycon, Karl Fosaaen presents techniques on how attackers can go after Azure resources. By understanding how attackers go after Azure resources, you can better protect your setup.Network monitoring is something that every company should be doing.

In fact, this system has a range of monitors, including server and application monitors.For the most repetitive task most of the administrator write a script to automate their day-to-day repetitive task.

Here we have written a shell Script that do not aims to automate the task of a typical system admin, but it may be helpful at places and specially for those newbies who can get most of the information they require about their System, Network, Users, Load, Ram, host, Internal IP, External IP, Uptime, etc. We have taken care of formatting the output to certain extent. In-fact it is recommended to run this script as user and not as root.

We have tried to customize the output to the extent that nothing other than the required output is generated. We have tried to use those variables which are generally not used by Linux System and are probably free. There is no dependency required to use this package for a standard Linux Distribution. However if you want to Install it, you need to enter root password once. We have taken care to ensure security of the system. No root access required to run.

Moreover code has been released under Apache 2. It is strongly advised to install the script as user and not as root. It will ask for root password and will install the necessary components at required places. Enter root password when prompted. If everything goes well you will get a success message like shown below.

After installation, you can run the script by calling command 'monitor' from any location or user. This script is working out of the box on a few machines I have checked.

It should work the same for you as well. If you find any bug let us know in the comments. This is not the end. This is the beginning. You can take it to any level from here.

An Overview of Networking Monitoring Tools

Because many organizations need their network to be up and functioning to generate revenue, having the right set of tools to monitor and manage the one you so lovingly created is critical.

But how do you find the best network monitoring tools when there are hundreds of commercial products, freeware tools, and open-source software to choose from? While the debate about free versus commercial goes on, there are tried and tested, free network monitoring tools that many network admins swear by.

network monitoring scripts

Below, we will share some of our favorites with you. Open-source choices are good and can even match commercial tools, but you should know that using open-source monitoring requires a high level of involvement with the tool, which may not perfectly suit your needs.

Open-source monitoring solutions often require a significant investment in time and resources. Missing features may have to be built with the help of community support or an in-house IT team. Additionally, immediate custom fixes may not be available unless you spend time developing and maintaining them yourself.

NPM acts as a single pane of glass to provide complete and comprehensive network monitoring capabilities that complement some of the essential free tools you may already use. Nagios is popular due to its active development community and external plug-in support. It allows you to collect data from almost any network element, including routing and switching systems as well as firewalls, and put that data into robust graphs.

Cacti supports SNMP polling, which itself covers a wide range of network devices. Cacti also allows you to add multiple users and give them access with or without edit permissions, which is perfect for service providers and enterprises with a large NOC team. You can install ntopng on a server with multiple interfaces and use port mirroring or a network tap to feed ntopng with the data packets from the network for analysis.

This level of traffic analysis helps you make informed decisions about capacity planning and QoS design and helps you find bandwidth-hogging users and applications in the network. Icinga was created in by the same group of devs that made Nagios, so they knew their stuff.

Since then, the developers have made great strides in terms of expanding both functionality and usability since then. As the Nagios pedigree might imply, its primary focus is monitoring infrastructure and services. You can also set up customizable notifications and restart services from within the app. Note that Spiceworks is free because most of its revenue comes from the sale of ad displays in its network. This is bolstered by the fact that the free version cannot scale past a single server.

Run this on your corporate network at your own risk! The free version also enjoys a 6-month patch and update cycle. One of the most painful features held back from the free version is the lack of alerting capabilities. Those caveats aside, you get a full auto-discovery of your devices and metrics using SNMP and standard protocols, as usual. It lets users capture traffic at wire speed or read from packet dumps and analyze details at microscopic levels.

Wireshark supports almost every protocol, and has functionalities that filter based on packet type, source, destination, etc. It can analyze VoIP calls, plot IO graphs for all traffic from an interface, decrypt many protocols, export the output, and lots more.

Wireshark provides unlimited opportunities to study packets, which makes it a solid go-to for network, system, and security admins.
