Overview: Web Application Security

Web application protection entails a multifaceted approach to defend against a plethora of vulnerabilities and attack vectors. It involves hardening the fortress walls with robust authentication and authorization mechanisms. Thereby ensuring only the worthy gain access to your application’s inner sanctum. Input validation, the noble art of scrutinizing user input with unwavering scrutiny, fends off dastardly injection attacks and cross-site scripting shenanigans.

Spoke technically, for web applications security solutions to deliver the desired content, a user must be able to communicate with the hosts’ network. If the web app is not hardened with security, it is possible to trick it to go back to the host database on which it is built. Thereby sending you any data that you or an attacker request, even if it involves transmitting confidential information.

Like any other software, when we build web apps from scratch, it is implied that the app would have a share of flaws. Few of these flaws represent genuine issues that can be employed against businesses. Web application security guards against these flaws. It involves utilizing secure development methodologies and Web AppSec through SDLC, making sure that both implementation and design-level glitches are fixed.

Ultimately, web application security is all about enabling web apps to operate smoothly and securely even when they are being attacked. This makes it essential for businesses to build different types of web applications that can sustain any notorious act of hackers.

How Does Web Application Security Work?

We hope that you got what you were looking for - the answer to why web application security is important. Now, let’s focus the lens on how it works. Developers use different strategies to fix vulnerabilities. Check out a few major ones here -

1. Web Application Firewall Solutions:

WAF Firewalls make use of both hardware and software. This preventative strategy is quite successful in stopping web app attacks. Typically, developers implement the firewall without changing your current application.

There are 3 primary web application firewall types that businesses consider on a frequent basis, namely, software-based WAF, hardware-based WAF, and cloud-based WAF. Firewall analyzes the incoming traffic – if it finds a cyberattack coming its way – it instantly turns up the BLOCK option.

Implementing a WAF security is crucial for securing applications, regardless of whether they are web apps or cloud apps

2. DDoS Protection:

DDoS restricts users from accessing the website by disrupting the normal function of your network or service. DDoS protection software could help your server fend off these attacks by defending your network and the relays that direct traffic to your site. Let’s check the specific considerations for DDoS protection in web apps vs websites -

Web applications often have complex functionalities and interaction points compared to websites. Hence, DDoS protection for web apps requires granular analysis and an understanding of application behavior.

Websites, on the other hand, are typically more straightforward and serve static or dynamic content to users. DDoS protection for websites focuses on traffic filtering and rate limiting at network level. Thus, efficiently mitigating high-volume attacks and ensuring uninterrupted availability of the website.

3. DNS Filtering:

Domain Name System (DNS) is similar to a directory for the internet. It analyzes prohibited websites using their IP addresses, thereby preventing you from accessing specific websites that may endanger your web application.

These were the major ways of how web application cybersecurity works. There are other web application security techniques as well, such as web application vulnerability scanner, cookie management, traffic visibility, user authentication and access management, and IP denylists.

After how to prevent web application attacks!? It’s time to learn about the different types of web app security that could help you leverage the best of both worlds.

Major Types of Web Application Security

One of the most common questions that organizations and developers ask these days is – How to ensure security in a web application? And our straight point is towards the various types of web application security that helps ensure that your web app is apt enough to combat any cyber threats. Let’s check out the major web app security types in brief -

1. Dynamic Application Security Test (DAST):

DAST dynamically tests digital assets for security vulnerabilities. It is a reliable web app and API security testing method that can discover vulnerabilities most accurately. The optimal approach is to combine DAST with some mechanical web security testing. This should be done in case of typical vulnerabilities for medium-risk apps going through minor changes.

2. Static Application Security Testing (SAST)

SAST concentrates on the application’s real code. It is a type of white box testing because you’re quite familiar with the way the code was created. SAST is majorly used by developers as it works best for finding bugs without requiring users to run programs in a real-world setting. Furthermore, it empowers programmers to scan source code for security flaws in software, systematically detect them, and fix them.

3. Interactive Application Security Testing (IAST)

IAST is the hybrid strategy comprising SAST and DAST. Its tools can determine whether the existing web application security vulnerabilities from SAST can be exploited in a running program DAST or not. These tools integrate data flow and application flow knowledge. This way, they visualize sophisticated attack scenarios using test cases. These use-cases are then used to construct new test-cases by iteratively utilizing DAST results.

4. Run-time Application Security Protection (RASP)

RASP technology makes it possible to assess runtime application traffic and user behavior. It seeks to assist in detecting and preventing cyber threats by gaining visibility into application source code, such as that for progressive web app development, and examining the vulnerabilities. To offer proactive security, RASP can spot security flaws that have already been exploited, stop such sessions, and send out alerts.

5. Manual Application Penetration Testing

Web application penetration testing is used in conjunction with automated application security testing to mimic an attack on an active application. It is a critical component of securing enterprise web application development and one of the most widely accepted methods for verifying the security of web applications. Open Web Application Security Project considers that web application penetration testing has 6 phases – planning and investigation, scanning, unintended access, permanent state of access, reporting, and retesting.

Interesting Facts

“Open Web Application Security Project (OWASP) is a globally recognized non-profit organization dedicated to improving the security of web applications. It provides valuable resources, tools and guidelines to help organizations and developers understand and address the most critical web application security risks.”

10 Common Web Application Security Risks

Web application cyber security is the art and science of safeguarding from the relentless onslaught of cyber adversaries. Picture it as an intricate web of defensive strategies, meticulously woven to thwart the malicious schemes of hackers, bots, and ne’er-do-wells.

But what are the main vulnerabilities of any web application?

Check out the major types of web application attacks reported by the OWASP -

1. Broken Access Controls:

The process through which an application limits access to data or functionality is referred to as broken access controls. When limitations on what users can do are not adequately enforced, BAC vulnerabilities arise.

2. Cryptographic Failures:

Cryptographic failures frequently result in the exposure of sensitive data or system breaches. Hence, exposing data such as session tokens or user credit card details on online applications and APIs.

3. Injection Flaws:

Under injection attacks, a web app accepts unverified data from an input variable without proper assessment. The most common injection issues include SQL, NoSQL, OS, and LDAP.

4. Insecure Design:

It focuses on dangers associated with design faults. Its inclusion emphasizes the value of reference architectures, web application security framework, secure design patterns, and threat modelling.

5. Security Misconfiguration:

It is used to characterize open cloud storage, inadequate configurations, and insecure default settings. Even a seemingly insignificant setup issue, like showing too much information in error messages, might pose a problem.

6. Poor Application Maintenance:

Applications and APIs that make use of outdated components could weaken application defenses and give attackers a point of entry. Maintaining the most recent versions of all web applications’ components parts is necessary to mitigate against such vulnerabilities.

7. Identification and Authentication Failures:

Broken Authentication is any security flaw that interferes with an application’s login process. Attackers are free to compromise user passwords and session tokens when authentication is breached. They can also take undue advantage of application defects. Systems may become susceptible to brute force assaults, in which hackers utilize computerized techniques to guess user account passwords.

8. Software and Data Integrity Failures:

Serialization is the process used in planning to turn an object into a stream of bytes for storage or transmission in memory, a file, or a database. The opposite of this process, deserialization, turns bytes back into an object that may be moved or transferred. Applications that execute deserialization on data that isn’t trusted such as data sent by an attacker to an application, are susceptible to this kind of vulnerability.

9. Security Logging and Monitoring Failures:

Failures in this category can directly affect visibility, incident alerting and forensics even though they are difficult to test for and aren’t adequately represented in the CVE/CVSS data. Serious breaches may go unnoticed, or action may be taken too late as a result of inadequate tracking and monitoring paired with a delayed or poor incident response.

10. Server-side Requests Forgery:

SSRF has been introduced as a new addition from the top 10 community survey. Despite being a new entry in the OWASP Top 10, the data reveals a low incidence rate, above average testing coverage, and above average scores for impact and exploit potential.
