In today’s digital age, web applications have become the backbone of online operations for both businesses and individuals. From online shopping and banking to entertainment and social networking, we increasingly rely on web applications to perform critical tasks. This reliance, however, has also attracted malicious actors seeking to exploit vulnerabilities in web applications for their gain.
These malicious actors can steal sensitive data, disrupt services, and damage systems, leading to financial losses, reputational damage, and legal liabilities. Therefore, web application security is paramount to protect data, maintain user trust, and ensure the integrity and continuity of online services.

What is Application Security?
Application security (AppSec) is the process of protecting software applications from external threats. This involves using security software and hardware, as well as implementing secure development practices, procedures, and methodologies. Organizations need application security technology to protect their entire application portfolio, from internal applications to popular external-facing applications.
Historically, software security focused on securing desktop applications and static websites, which were relatively secure and easy to scale. However, the software supply chain has become increasingly complex due to outsourced development, legacy applications, and internal development using software modules from various sources (third-party, open-source, commercial off-the-shelf).
Types of Application Security
Web application security
Web applications are programs that reside on web servers and are accessible over the internet. Clients access web applications using a browser. Due to the inherent need to allow connections from clients over an insecure network, web applications are exposed to a wide range of risks. Many web applications are mission-critical and contain sensitive customer data, making them attractive targets for attackers.
Web applications, due to their exposure to users over the internet, face a wide array of attacks. Common vulnerabilities include:
- Cross-Site Scripting (XSS): Attackers inject malicious code (often JavaScript) into a website, which is then executed on the computers of other users when they visit the site. XSS can lead to cookie theft, session hijacking, or redirecting users to malicious websites.
- SQL Injection: Attackers exploit vulnerabilities in an application to inject malicious SQL code into the database. This can allow them to access, modify, or delete data without authorization, potentially even taking control of the entire system..
- Cross-Site Request Forgery (CSRF): Attackers trick users into performing unwanted actions on a web application that they are already logged into. For example, an attacker could send a malicious link that causes the user to unknowingly transfer money from their bank account.
- Broken Authentication: Vulnerabilities in the user authentication process can allow attackers to gain unauthorized access to user accounts or even take control of the system.
- Sensitive Data Exposure: Sensitive data such as personal information, financial information, or health information is not properly protected, leading to the risk of theft or exposure.
- Security Misconfiguration: Misconfigured web servers, frameworks, or applications can create security vulnerabilities. For example, failing to disable unnecessary features or not updating software regularly can leave an application vulnerable to attack.
- Using Components with Known Vulnerabilities: Using libraries, frameworks, or other components with known security vulnerabilities can make an application susceptible to attack.
API security
APIs contain security vulnerabilities that can lead to serious data breaches. API security vulnerabilities include insufficient authentication, unintentional data exposure, and a lack of rate limiting, which can facilitate API abuse. Sophisticated tools are being developed to detect API vulnerabilities and protect APIs in production environments.
APIs (Application Programming Interfaces) allow different applications to communicate with each other. However, APIs can also contain security vulnerabilities, including:
- Broken Object Level Authorization: Attackers can gain unauthorized access to data objects (e.g., user profiles, orders) that they should not have access to.
- Broken User Authentication: Vulnerabilities in the API authentication process can allow attackers to impersonate legitimate users and gain unauthorized access to resources.
- Excessive Data Exposure: APIs return more data than necessary, including sensitive information, creating a risk of data leakage.
- Lack of Resources & Rate Limiting: Not limiting the number of API requests that a user can send can facilitate denial-of-service (DoS) attacks.
- Broken Function Level Authorization: Attackers can gain unauthorized access to API functions that they should not be able to use.
- Mass Assignment: Attackers exploit vulnerabilities in the input data handling process to modify object properties that they are not authorized to change.
- Injection: Similar to web applications, APIs can also be vulnerable to injection attacks, such as SQL injection, command injection, or NoSQL injection.
Cloud-native application security
The infrastructure and environments of cloud-native applications are typically automatically built based on declarative configurations, also known as Infrastructure as Code (IaC). Shift-left security, which focuses on integrating security early in the development lifecycle, is crucial in cloud-native settings. Specialized cloud-native security solutions are required to inspect containers, clusters, and serverless workloads, and provide rapid feedback to developers.
Cloud-native applications are designed to run on cloud platforms and leverage cloud services. Specific security risks associated with this type of application include:
- Misconfigurations and Inadequate Change Control: Misconfigurations or inadequate change management in the cloud environment can create security vulnerabilities.
- Insecure Interfaces and APIs: Insecure interfaces and APIs can allow attackers to gain unauthorized access to cloud resources.
- Lack of Cloud Security Architecture and Strategy: Lack of a clear cloud security architecture and strategy can lead to inadequate implementation of security measures.
- Insufficient Identity, Credential, Access Management: Inadequate identity, credential, and access management can allow attackers to gain unauthorized access to cloud resources.
- Account Hijacking: Attackers take control of cloud accounts and gain access to sensitive data and resources.
- Insecure Third-Party Dependencies: Using insecure third-party libraries, services, or components can create security vulnerabilities.
- Data Breaches: Data leaks or theft due to misconfigurations, application vulnerabilities, or unauthorized access.
