What are the Top 10 Web Application Security Vulnerabilities (The OWASP 10)

Application Security - Blog

A web application security check is becoming increasingly essential as more transactions have occurred online and a lot more people are accessing information through the web.

Applications Security focuses on protecting software from cyber attacks. Applications should apply software security throughout the entire development phase, including development, design, and deployment. List some ways of ensuring software security in the software development lifecycle:

What Are the 3 Types of Penetration Testing?

For detecting vulnerabilities in web apps, there are three kinds of pen tests available: black boxes testing, and white and gray boxes testing. Utility companies must assess risks for ICS systems / SCADA systems and substations. A call center must determine a patient’s health information. Health care facilities must ensure patient health and information cannot be violated. Schools should review safety protocols.

Retailers can evaluate whether an attack is imminent on their retail premises. A financial institution should assess the risk of an attacker at a branch. Organisation must upgrade physical protection and assess the effectiveness of the latest security updates.

  1. Test for Dynamic Application Security (DAST). Internally facing, low-risk apps that have to pass regulatory security evaluations are the ideal candidates for our automated application security test. The optimal approach is to combine DAST with some manual web security testing for common vulnerabilities for medium-risk apps and important applications going through minor modifications.
  2. Test for Static Application Security (SAST). Both automated and manual testing methodologies are available with this application security strategy. It works best for finding flaws without requiring users to run programs in a real-world setting. Additionally, it gives programmers the ability to scan source code for security flaws in software and systematically detect and fix them.
  3. Penetration test. For essential applications, especially those undergoing significant modifications, this manual application security exam works well. Business logic and adversary-based testing are used in the evaluation to find sophisticated attack scenarios.

Finding security flaws in Web applications and their settings is the goal of web security testing. The application layer is the main target (i.e., what is running on the HTTP protocol). Sending various inputs to a Web application to elicit errors and cause the system to react unexpectedly is a common practice for testing its security. These so-called “negative tests” check to see if the system is performing tasks that it wasn’t intended to.

It’s also critical to realise that testing for web security encompasses more than just the login and authorisation mechanisms that may be included in the application. It is similarly crucial to verify that other features—such as business logic and the usage of appropriate input validation—are implemented safely. The objective is to guarantee the security of the functionalities exposed in the Web application.

Security for Web Applications

Software that is available over the Internet and is hosted on a web server is referred to as a web application. In a web browser, the client is used. Applications are compelled to allow connections from users over insecure networks by nature. They become vulnerable to several threats as a result.

A primary priority for any cyber security program is to protect online apps, which are frequently business-critical and contain sensitive customer data, making them an attractive target for attackers.

The advent of HTTPS, which establishes an encrypted communication channel and defends against man in the middle (MitM) attacks, is one example of how the Internet’s growth has addressed web application weaknesses.

However, there are still many weaknesses. The Open Web Application Security Project has a list of the most serious and widespread flaws (OWASP), as represented by the OWASP Top 10.

Numerous security companies have released solutions specifically tailored to safeguard online applications in response to the rising challenge of web application security. One example is the web application firewall (WAF), a security technology intended to identify and prevent threats at the application layer.

API Safety

The significance of application programming interfaces (API) is increasing. Modern microservices apps are built on top of them, and a whole API market has sprung up that enables businesses to share data and get access to third-party software capability. In light of this, API security is essential for contemporary businesses.

Major data breaches are caused via APIs that have security flaws. They may reveal private information and cause disruptions in business activities.

OWASP Top 10 Web Application Security Risks

Numerous dangers may damage software programs. Critical application risks that are most likely to have an impact on applications in production are included in the Open Web Application Security Project’s (OWASP) Top 10 list.

Ineffective Access Control

Threats and users can get privileges and access that are not allowed due to faulty access control. These are the most typical problems:

It gives attackers the ability to enter user accounts without authorisation and pretend to be administrators or normal users.

Users are given illegal access to privileged functions.

Strong access mechanisms that guarantee each role is precisely specified with isolated privileges can be used to address this problem.

Failures in Cryptography

When data is improperly secured while being transported and there are cryptographic failures.

This application security risk may result in noncompliance with financial requirements like PCI Data Security Standards and data privacy laws like the EU General Data Protection Regulation (GDPR) (PCI DSS).

Injection (Including XSS, LFI, and SQL Injection)

Threat actors can deliver harmful data to a web application interpreter thanks to injection vulnerabilities. It may result in the compilation and execution of this data on servers. A typical type of injection is SQL injection.

Many application flaws introduced by inefficient or absent security safeguards are covered by the insecure design. Applications that lack fundamental security measures are vulnerable to critical

Failures in Authentication and Identification

Any security issue involving user identities is referred to as identification and authentication failures. By implementing secure session management and setting up authentication and verification for all identities, you can defend against identity attacks and vulnerabilities.

Failures in Data Integrity and Software

When infrastructure and code are susceptible to integrity violations, software and data integrity problems arise. It can happen during software upgrades, the alteration of sensitive data, and any unvalidated CI/CD pipeline modifications. Supply chain attacks and illegal access are both possible outcomes of insecure CI/CD pipelines.

Failures in Security Logging and Monitoring

When application flaws prevent applications from adequately detecting and responding to security incidents, security logging and monitoring failures (also known as “insufficient logging and monitoring”) occur.

In summary, the OWASP top 10 are:

  1. Injection
  2. Sensitive data exposure
  3. Broken authentication
  4. XML external entities
  5. Security misconfiguration
  6. Broken access control
  7. Cross site scripting
  8. Insecure deserialisation
  9. Using components that have known vulnerabilities
  10. Insufficient monitoring and logging

Web security application security testing techniques vary depending on the needs of your business and the foundation of your website application. Security testing for websites ensures you identify security threats your website application might face. Mobile application security testing is also another crucial part of ensuring all your applications are secure.
