Over the years, the online business landscape has evolved due to rapid advancements in technology and the adoption of assets that offered feasible IT environments to organizations that made them more secure and efficient for running their operations online.
However, while expanding online, cyber risks also increased with more targeted attacks against organizations ranging from small to large to disrupt their businesses and revenue. Since the last decade, there has been a steady increase in cybercrimes and newly introduced hacking techniques.
Today, we are seeing thousands of businesses getting targeted with malware, DDoS attacks, and whatnot. According to a recent report by the FBI, during this COVID-19 pandemic, cyberattacks on businesses have increased by 300% more. Another report by IBM states that the average cost of a data breach reached $4.24 million in 2021 from $3.86 million in 2020.
Performing an IT security audit can help organizations by providing information related to the risks associated with their IT networks. It can also help in finding security loopholes and potential vulnerabilities in their system. Thereby patching them on time and keeping hackers at bay.

Emphasizing the importance of security, Bill Gates once remarked,
Security is, I would say, our top priority because for all the exciting things you will be able to do with computers – organizing your lives, staying in touch with people, being creative – if we don’t solve these security problems, then people will hold back.
So, let’s dig deep and find out what is an IT security audit, how to do it, and its benefits for online businesses:
What is IT Security Audit?
An IT security audit is a comprehensive assessment of an organization’s security posture and IT infrastructure. Conducting an IT security audit helps organizations find and assess the vulnerabilities existing within their IT networks, connected devices, and applications. It gives you the opportunity to fix security loopholes, and achieve compliance.
This includes things like vulnerability scans to find out security loopholes in the IT systems. Or conducting penetration tests to gain unauthorized access to the systems, applications, and networks. Finally, the penetration testing reports generated after performing all the necessary procedures are then submitted to the organization for further analysis and action.
An IT security audit also comprises the physical part. In which, the auditor verifies physical hardware access for security and other administrative issues. However, this article only covers the non-physical part of an IT security audit.

Benefits of IT Security Audit
As we mentioned, an IT security audit reveals underlying vulnerabilities and security risks in an organization’s IT assets. Identifying risks, however, has a positive rippling effect on the organization’s overall security. How? We discuss them point by point below:
- Weighs your current security structure and protocols and helps you define a standard for your organization with the audit results.
- Mitigates hacker-risks by discovering potential hacker entry points and security flaws well in advance.

Types of IT Security Audit
There is more than one way to categorize an IT security audit. Generally, it’s been categorized on the basis of approach, methodology, etc. Some of the common categorizations are:
- Black Box Audit: Here, the auditor only knows about the info that is publicly available regarding the organization that is to be audited.
- White Box Audit: In this type of security audit, the auditor is provided with detailed info (i.e. source code, employee access, etc) regarding the organization that is to be audited.
- Grey Box Audit: Here, the auditor is provided with some info, to begin with, the auditing process. This info can also be gathered by the auditors themselves but is provided to save time.
- Penetration Tests: The auditor tries to break into the organization’s infrastructure.
- Compliance Audits: Only certain parameters are checked to see if the organization is complying with security standards.
- Risk Assessments: An analysis of critical resources that may be threatened in case of a security breach.
- Vulnerability Tests: Necessary scans are performed to find possible security risks. Many false positives may be present.
- Due Diligence Questionnaires: Used for an analysis of existing security standards in the organization.

How to conduct an IT security audit for your business? [With tools]
Before beginning with the process of security audits, it is important to use the right set of tools. Kali Linux is one such OS that is customized and contains a bundle of tools to conduct a security audit. This OS can be used by installing on a separate machine or making the present machine dual-booted or on a virtual machine. To install it on a virtual machine, follow this article.
Once everything is set, let’s begin!
1. Recon Dog
While doing a black box IT security audit, it is necessary to gather some info about the target like CMS being used, etc. This would help in narrowing down and targeting the precise security weak points. Recon dog is just the right tool for this purpose. This tool requires no installation so download it from here and start using it as a normal script.
Alternatively, you can open up your terminal in Kali and type:
git clone https://github.com/s0md3v/ReconDog
This will save it into a directory called ReconDog. Now navigate to the directory and run it using the following commands:
Thereafter, an interface will open asking you for the type of recon you wish to perform. Once you enter the recon option, it will ask for the target URL. After typing it, press enter and the scan will start.
Another great tool to conduct an IT security audit is Nmap. It can be used to discover open port vulnerabilities and to fingerprint the network internally as well as over the internet. To use this tool, open the terminal in Kali and type:
nmap -v -sS -A -T4 target
Replace target with the IP address you wish to scan. This command runs a stealth scan against the target and tries to detect the Operating system and its version. For more help type:

Nikto is another great tool to find vulnerabilities in the server. Use it to discover all kinds of potential server misconfigurations. However, it also generates a lot of false positives so they need to be verified by exploiting. To scan your site using Nikto, open the terminal in Kali and type:
nikto -h www.your-site.com
For more help type:
4. Metasploit Framework
Metasploit is perhaps one of the most powerful exploitation frameworks used to conduct an IT security audit. All the potential vulnerabilities discovered using Nikto can be checked using Metasploit as it contains a large number of exploits. To use them, open the terminal in Kali and type:
This will load the Metasploit framework. For further using Metasploit, read this article.
Is your website often hacked? Secure my website now!
While conducting an IT security audit, it is important to check for common web injection vulnerabilities like SQL injection and cross-site scripting. To tool used to check for XSS vulnerabilities in your website is Xsser. To use it, open the terminal in Kali and type:
This will open a graphical interface like the one in the image given below. Just set the necessary options and start hunting for XSS bugs!
To check for SQLi bugs on your site, there is no better tool than Sqlmap. Firstly select a parameter you wish to test. Thereafter, open the terminal in your Kali and type:
sqlmap -u "www.your-site.com/page?param=1" --dbs --random-agent --batch
Replace the URL part with the URL of your site and page with the name of the page you wish to test for SQLi and param with the parameter you wish to check. Thereafter, this command will automatically try to exploit SQLi bugs and enumerate the database names to you. For more info type:
