Top Security Threats and Security Analysis Tools for Front-end Developers

That’s not how you’d want to protect your estate, right? You’d want a fence to go with that gate.

In the digital domain, that translates to keeping your website and online data secure and protected from unauthorized access. 

Websites have a front-end and a back-end. They need different security tools. When you hire front-end developers they should be well-versed with these tools. This post focuses on the top security analysis tools that front-end developers must know about and apply. 

Two Levels of Front-end Security

The front-end of a website is the part that your visitors and clients interact with. Even then, there are two dimensions to front-end security :

Keeping Your Clients’ Data Safe

This in itself is a vast topic. A lot of your customers’ personal data will be on your website. It is part of your responsibility to protect such information from leakage or hacking. 

Keeping Your Own Data Safe

You need to prevent customers/visitors to your website from accessing your own data that they do not need to see. This is where front-end-security meshes with back-end security.

The first step for both is to detect the security threats that your front-end may be exposed to.

Top 10 Threats to the Safety of Your Clients’ Data

We briefly describe the security threats from the OWASP (Open Web Application Security Project) Top 10 list. These threats represent a global consensus on the most critical and common front-end vulnerabilities.

Threat 1. SQL Injection Attacks

SQL vulnerability is one of the most prevalent security threats. Many high-level data scams in recent times have been carried out using SQL injections. It is a code injection technique used to conduct attacks against data-dependent applications. 

SQL injection is the technique by which an attacker manages to interfere with the questions the app sends to its database. That is how they gain access to unauthorized data.

A 2017 post says that hackers use this method in 51% of their attacks. 

Threat 2. Broken Authentication

Incorrect implementation of authentication and session management is a serious threat. That allows cyber-criminals to compromise keys, passwords, or session tokens. It may facilitate an attacker to impersonate other users for a while or forever.

A 2019 vulnerability assessment report says 9 out of 10 web applications are vulnerable to hacking attacks. The application code is the location of 82% of the threats.

We invite you to consider the following graph carefully.

A 2019 vulnerability assessment report says

Notice that there has been a considerable reduction in high-level and low-level threats from 2018 to 2019. Medium-level threats have increased, however. 

Now notice the whole graph carefully once more. High-risk threats were high in 2015 and then reduced over the next two years. They shot up again in 2018 and reduced in 2019. 

There’s a clear pattern. 

  • As protection mechanisms improve, cyber-criminals find newer ways of attacking. 
  • When high-level threats decrease, mid-level threats rise, 

These are important points to remember when you decide which threat analysis tool you want to use.

Threat 3. Sensitive Data Exposure

Sensitive data needs special protection like encryption during rest or transit. Exchanging such data with the browser needs special precautions. Web applications and APIs sometimes do not code such special protections. That enables credit card fraud, identity theft, and similar other serious cyber-crimes.

Threat 4. XML External Entities (XXE) Injection

This allows an attacker to interfere with the way an application processes XML data. It happens because of older versions of XML. Also due to poor configuration. XXE facilitates the attacker’s access to the app’s server file-system. 

The attacker can interact with any back-end systems or external systems accessible to the app. This vulnerability includes disclosure of internal files, internal file shares, remote code execution, etc. 

It is also possible to leverage XXE vulnerability to execute Denial of Service (DOS) attacks, or Server-Side Request Forgery (SSRF).

Threat 5. Broken Access Control

Poor enforcement of what authenticated users can and cannot do is a vulnerability. Cyber-criminals can use such gaps to gain unauthorized access to data and/or functionality. The results can be dangerous as it allows the attacker to change other users’ data, modify access rights, or even delete crucial data.

Threat 6. Security Misconfiguration

This is one of the most prevalent vulnerabilities. Ad hoc or incomplete configurations, insecure default configurations, misconfigured HTTP headers, and open cloud storage are the typical examples. 

Wordy error messages also contain sensitive information sometimes. Irregular patching/upgrading is another instance of security misconfiguration.

Threat 7. Cross-site Scripting (XSS)

This is a vulnerability of web applications that allows an attacker to bypass access controls like the same-origin policy. The attacker can vandalize websites, or redirect the user to malicious sites, etc. It also facilitates injecting malicious elements in a benign or trusted website.

Threat 8. Insecure Deserialization

This weakness can cause remote code execution as it allows the attacker’s data to be accepted without verification. Data theft, data modification, injection attacks, privilege escalation attacks, replay attacks, etc, can all happen because of this lapse. 

Threat 9. Using Components Known to be Vulnerable

Using components that are known to be vulnerable weakens the defense of an application. That can lead to attacks ranging from data loss to server hijacking.

Threat 10. Inadequate Logging and Monitoring

This gap allows cyber-criminals to continue attacking systems persistently over a period of time. That creates a scope to access more systems and destroy, mess up, or steal huge amounts of data.

How the Threats Compare

The graph below reflects clearly the relative prevalence of 10 threats we have described above.

The Top 7 Free Security Analysis Tools

Now that you know the most prevalent vulnerabilities, you need to detect if your system is vulnerable to any or all of these. This is where front-end security analysis tools come in.

There are both open-source and commercial tools in the market to analyze security threats. We have selected the best from the free tools only. In-depth research, including user reviews, constitute the basis of our selection. 

We have included tools that can detect the top 10 vulnerabilities we have described, ala OWASP. 

Just one word of caution before we begin. Security testing needs to be a part of the website development process – not an afterthought. 


OWASP Zed Attack Proxy. That’s the full name of ZAP. It is one of the most popular and widely used security analysis tools. Companies like Google and Microsoft use it. 


  • Free to download and easy to use, it supports both manual and automated testing. 
  • Platforms like Linux, Mac OS, and Windows support it. It comes with a wide variety of features that enable efficient penetration testing. 
  • Strong community support is another advantage of ZAP. Also, updates including new vulnerabilities are consistently regular.
  • You can use a number of plugins and integration with tools like Jenkins considerably heightens ZAP capability.


  • According to users, the only area of improvement for ZAP is its reporting. Its reports are not as comprehensive as its security scans. 

Tool 2. Arachni
