In the digital world, where businesses rely heavily on software and websites, the first line of defense is ‘security testing.’

As the saying goes, ‘One Single Vulnerability Is all An Attacker Needs.’ ‘Be Secure and Protect Your Data.’

Moreover, for the same reasons we lock our houses and valuables for their safety in the physical world, our businesses and customers must do the same in the digital world.

Now, it’s more important than ever since cyber threats are rising. 

In this blog, we will explore the amazing tools and best practices we use at ThinkPalm to ensure everything stays safe online. Let’s jump in!

What Is Security Testing?

Security testing is like checking a car before it hits the road.

We want to ensure it’s in the best possible condition.

In the digital world, we do the same for software and websites.

We look for any weak points that could be trouble, like easy-to-guess passwords or parts of the system that aren’t set up quite right.

But here’s the fun part: we don’t wait until the software is live for everyone to use.

We do this check while it’s being built, just like inspecting a bridge before cars drive on it.

This way, we catch and fix problems early before they cause any potential harm.

It’s like making sure your home is safe and secure before anyone tries to break in.

That’s why security testing is so important.

Why Security Testing Really Matters?

Have you ever wondered why we do security testing?

Here are some key reasons:

  • Spotting Hidden Threats: Think of security testing as a digital detective. It helps us find potential threats lurking in our systems.
  • Hunting for Weak Spots: We use security to find vulnerabilities, threats, and risks in apps and websites. Moreover, it’s like finding weak spots in a fortress.
  • Helping Developers Build Safely: Security testing is like a guide for developers. In addition, it shows them how to make their code secure while they’re building it.
  • Detecting Issues Early: We believe in finding security problems as soon as possible, like finding a small leak before it floods the whole house.
  • Tools for Everyone: We ensure all developers can use security tools, like giving everyone a shield to protect their work.
  • Preventing Future Troubles: By tackling security issues before we finish and release our software, we ensure a smoother journey without unexpected storms later on.

3. Nmap Tool

Nmap, the open-source network scanning tool, is a powerful asset in our toolkit.

Nmap Tool

It helps us manage our network effectively by discovering devices, finding open ports, and identifying vulnerabilities. Here’s an overview of how it works and the key scan types:

Tool Overview:

  • Device Discovery: Nmap assists us in finding devices operating on our network.
  • Port Detection: It discovers open ports and services running on those ports.
  • Vulnerability Detection: Nmap helps us identify potential vulnerabilities in our network.
Scan Types:
  • TCP Scan: We use this when we need a detailed analysis of a host. TCP scans are thorough and use a connection-based protocol.

Command: sudo nmap -sT -T4 -Pn -p1- <host>

  • UDP Scan: For faster results and to detect open UDP ports, we opt for UDP scans. Also, since UDP is a connectionless protocol, it makes this scan quicker.

Command: sudo nmap -sU -T4 -Pn –max-retries 2 -p1- <host>

  • Service Scan: This scan type helps us identify the services running on a host. Moreover, It’s vital for understanding the software and versions in use, which is crucial for security assessments.

Command: sudo nmap -sV -T4 -Pn -p1- <host>

Broad Capabilities of Nmap

Here’s a breakdown of the primary uses and capabilities of Nmap:

  • Scan Every Active IP Address: Nmap enables you to gather detailed information on every active IP address on your network to determine whether an IP has been compromised. The Nmap tool will let you know whether the IP address is being used by a legitimate service or by an external hacker.
  • Perform Entire Network Scanning: Nmap provides comprehensive information about your entire network, including a list of live hosts, open ports, and the operating system of every connected device. Due to this, Nmap does an excellent job at monitoring your ongoing system and helping perform pen-testing.
  • Identify the Vulnerabilities of the server: You can use the Nmap tool to scan your web server for any security breaches or gaps to protect personal and business websites. Also, Nmap helps simulate the process a malicious agent typically uses to attack your website.
  • Develop Visual Mappings: Nmap includes a graphical user interface known as Zenmap. You can also use it to build visual mappings of your network to improve usability and reporting.
  • Automate System and Vulnerability Scans: Nmap has an incredible “Nmap Scripting Engine” (NSE) feature. It’s a scripting engine that lets you use a predefined set of scripts and automate networking features.

Penetration Testing (Pen Testing)

Penetration Testing, or Pen Testing for short, is another crucial security testing method used to identify vulnerabilities, threats, and risks in software applications, networks, or web applications. It’s like having ethical hackers simulate attacks to discover security weaknesses that need fixing.

Here’s the basic idea:

  • Purpose: We do it to find and fix security issues in our software.
  • Ethical Hacking: We have friendly hackers who try to break into our systems to see if they can find any weaknesses.
  • Part of Security Strategy: Pen Testing is important to our overall security plan.

Although pen testing is mostly manual, pen testers use automated scanning and testing tools.

They not only utilize tools but also apply their knowledge of the latest attack techniques to perform more comprehensive testing than what a vulnerability assessment, primarily relying on automated testing, can offer.

Manual Pen Testing

Manual penetration testing goes beyond the scope of popular vulnerability lists like the OWASP Top 10.

It identifies vulnerabilities and weaknesses that automated testing may miss, particularly in areas such as data validation and integrity checks, which involve intricate business logic.

Additionally, manual penetration tests help in distinguishing false positives that automated testing tools might report inaccurately.

Due to the expertise of penetration testers who emulate adversarial thinking, they can analyze data to tailor their attacks, assessing systems and websites in ways that automated testing solutions cannot replicate.

Automated Testing

Automated testing offers the advantage of producing results more rapidly and requiring fewer specialized professionals compared to a fully manual penetration testing process.

These automated testing tools automatically track results and often allow for easy export to a centralized reporting platform.

In contrast, manual penetration tests can yield varying results from one test to another, while running automated testing consistently on the same system will consistently produce the same results.

Penetration testing, whether manual or automated, is essential to our security strategy. It helps us proactively identify and address security vulnerabilities, ultimately strengthening our security posture and protecting our software, networks, and web applications from potential threats.

Burp Suite Tool

Burp Suite, often referred to as Burp, is a versatile toolkit designed for web application penetration testing.

Burp Suite Tool

This tool includes an intercepting proxy that allows users to view and modify the content of requests and responses while they are in transit.

It streamlines the process of sending requests and responses to other tools within Burp Suite, eliminating the need for manual copy-pasting.

The proxy server can be configured to run on a specific loop-back IP address and port, and it can also be customized to filter specific types of request-response pairs.

Why Use Burp Suite in Security Testing

Burp Suite serves as a comprehensive framework for various security testing activities, including:

  • Web Crawling: Burp Suite can crawl web applications, systematically exploring their structure.
  • Web Application Testing: It facilitates both manual and automated testing of web applications.

Additionally, Burp Suite seamlessly integrates with the Chrome browser, enhancing its usability.

Using Burp Suite in Security Testing

To use Burp Suite in security testing:

  1. Open Burp and start a new project. Access the proxy settings and open your web browser.
  2. Burp Suite offers two scanning options: automatic scanning and manual exploration for broader coverage.
  3. Burp Suite acts as an interceptor between your browser and the web application (cluster). It handles requests (GET) and responses (POST) throughout the cluster’s API.
  4. Explore all clusters by navigating through each tab and adding items such as VMs, MFA, users, SNMP, policies, protection, recoveries, etc.
  5. After thoroughly exploring all clusters, initiate an attack using the Active Scan feature.
  6. The scan typically takes around 1 to 2 hours to complete. Once finished, you can export the scan report.
  7. Review the Burp report. If there are false positives, you can disregard them. However, if security issues and vulnerabilities are identified, you can flag them for developers through Jira.

View Alerts And Alert Details

Security testing is not just about running tests and scans; it’s also about understanding and acting upon the results.

In our security testing process, the left-hand side of the Footer contains a count of the Alerts found during the test, categorized by risk.

These risk categories serve as a guide to help us prioritize and address vulnerabilities effectively.

These risk categories are:Burp suite tool (View Alerts And Alert Details)

Forensics Tool

Forensics Tool is a special software developed for advanced data management solutions.

It helps gather logs and important data from a local computer system so that experts can investigate digital issues.

Here’s what it does:

  • Provides detailed insights into user actions, including logins and command usage.
  • Vigilantly monitors for any potentially malicious activities, such as password alterations.
  • Detects and lists active network connections, secure shell logins, and alterations to files and data.


To install the tool, follow these steps:

  • Download the package to one of the nodes using scp or wget.
  • Use to transfer the RPM to all nodes of the cluster ( <rpm-package-location> /tmp).
  • Install the RPM package on all nodes using ‘sudo rpm -U /tmp/<rpm-package-name>’.


The tool requires execution with sudo privileges. Otherwise, it will fail with an error.


[-node-1 ~]$ sudo ./forensics/crux/bin/forensics_exec -h

Copying Results

The tool generates a .tgz bundle at the path specified by the ‘output_dir’ parameter, which is typically stored in timecapsules.”

Uninstall and Cleanup

To uninstall the tool on all nodes and clean up:

Forensics bundles are stored in either “timecapsules” or “output_dir” as specified by the user. Users can copy the .tgz bundle remotely using scp. Afterwards, they can clean up the bundle on the node. The tool does not automatically clean up previous bundles to prevent accidental deletion of important forensics.

To uninstall the tool on all nodes, use the following command:

# Uninstalling the tool

# The RPM name can be found using the “rpm -qa” command. ‘sudo rpm -e <rpm-name>’

To delete the RPM package from all nodes (if it was copied to /tmp on all nodes), use the following command: ‘rm /tmp/<rpm-package-name>’

Data stored in each directory are as follows:

  • Software Directory:
    • Contains changes to device protos (UserProto and ConfigProto).
    • Stores metadata related to software, including binaries and config files.
  • DataBackupIntegrity Directory:
    • Captures information about the stability of data processes.
  • LinuxSW Directory:
    • Tracks the integrity of files specific to Linux systems using last modified dates and RPM database to detect tampering/modifications.
  • LogBundle Directory:
    • Captures command outputs useful for forensics.
    • Preserves system log files with their original directory structure.
  • ShellLogins Directory:
    • Records all shell logins (e.g., ssh, teleport) that occurred within a specified time interval.
  • UserActivity Directory:
    • Captures user activities, including host shell interactions.
    • Logs IRIS CLI command history for a specific node.
  • NodeAnalysis.csv:
    • Contains information about suspicious events found in log files for a specific node.
