How to Make Security for Web Applications Ironclad

Table Of Contents

    Around 51% of organizations are planning to increase their investments in improving security for web applications, as per recent research from IBM.

    However, it is important to note that application security is not a one-time purchase or investment but an ongoing and long-term process. It's a combination of the right tools, used by people with the right skills while applying the right processes.

    In short, web app security needs you to build a culture of software security best practices in your development team. Otherwise, you could be missing an opportunity to catch on with the rest of the leading software development companies.

    While adhering to the security framework and best practices is helpful, adding security testing tools or working with a web app pentest services company is actually what the top decision-makers in your shoes are focusing on.

    By leaving your web apps with weak security controls you are literally inviting attackers through your front door to conduct cyber-attacks and data theft.

    As you know, data theft restoration usually costs millions of dollars, which is money that would otherwise have been spent on growth initiatives and building your team. The unquantifiable aspect of software or application security security neglect is the damage to your personal and corporate reputation in the long run.

    After all, being associated with a company that values software security and makes the effort to include the right automated testing tools in their SDLC and CI/CD pipelines is noteworthy mention. Be it on your LinkedIn or in your next interview.

    To protect applications from ever-evolving security risks, such as using components with known vulnerabilities, your developers must adopt a multifaceted approach to application security that combines manual security testing techniques and automation software testing tools and follow SaaS security best practices.

    Would it help to give your devs a cheat sheet of application security controls they must build into your SaaS and web apps?

    Let me tell you about the common web application security threats caused by vulnerabilities in web applications and what you can do to protect your applications.

    Top 10 Common Web Application Security Risks

    Injection Attacks

    Injection attacks like remote code execution involve cybercriminals inserting malicious code or SQL queries into input fields, exploiting vulnerabilities in web applications that can lead to data breaches or unauthorized access.

    They often target applications that handle user-generated content. The key to mitigating these software security risks is thorough input validation and the use of prepared statements or parameterized queries.

    Cross-Site Scripting (XSS)

    XSS attacks occur when hackers embed malicious scripts into web app pages that unsuspecting users execute within their browsers.

    This common web application security misconfiguration can lead to the theft of sensitive user data or session hijacking. You can prevent cross-site scripting (XSS) by ensuring proper input validation on the server side and escape output so that your application treats the content as data, not code.

    XSS vulnerabilities in web applications are often introduced when using vulnerable and outdated components.

    Broken Authentication

    Weak authentication mechanisms can open the door to unauthorized access. Inadequate password policies, session management flaws, and improper credential storage can lead to broken access control that makes your application vulnerable.

    To protect your application security> against this risk, you can employ strong authentication practices, implement multi-factor authentication, and regularly review session management mechanisms.

    Insecure Direct Object References

    Attackers can exploit insecure direct object references by manipulating input parameters and gaining access to unauthorized data or files. Securing authorization mechanisms, access control lists and careful handling of user inputs for web servers can help you mitigate this web application security risk and minimize the chance of data integrity failures.

    Security Misconfiguration 

    Improperly configured security settings can expose web application vulnerabilities. You must review and configure security settings properly. This includes permissions, encryption, and error handling for your applications. You also need to conduct regular audits of your application's configuration to prevent this security misconfiguration.

    Sensitive Data Exposure 

    Not protecting sensitive data, such as credit card numbers and personal information, on your apps can lead to data theft. To prevent sensitive data exposure, you can employ encryption, strong access controls, and secure data storage at rest and in transit. Compliance with data protection regulations like GDPR and PCI DSS for your applications is also necessary.

    XML External Entity (XXE) Attacks 

    External entity attacks usually happen when internal secrets attackers leverage vulnerable XML processors and can gain access to internal files, potentially revealing sensitive information. To protect your software against XXE attacks you need to disable external entity processing and employ proper validation of XML input.

    Broken Access Control

    When access controls are improperly implemented, unauthorized users can access restricted resources. To prevent identification and authentication failures, you need to implement fine-grained access control and conduct thorough testing to ensure that users only have access to what they should.

    Security Through Obscurity

    Relying on secrecy rather than robust security measures for web app API vulnerability threats detection is a very dangerous gamble.

    Security through obscurity can lead to vulnerabilities being overlooked or underestimated. Always follow software security best practices, OWASP Top 10 guidelines and employ automated security testing tools that allow you to document security incidents.

    Inadequate Logging and Monitoring

    You lack visibility into security events and breaches without adequate logging and monitoring. You can prevent this by implementing comprehensive logging and monitoring solutions to detect and respond to security incidents promptly.

    If you're building API-based applications, an important aspect of proper logging and monitoring comes from the use of an end-to-end API security tool that automatically discovers your API endpoint and helps you identify and remove shadow APIs.

    Ideally, any automation tools should run straight from your CI/CD pipelines.

It's imperative to document and track your progress to ensure that web application security issues are addressed.

    Step 4: Verification

    After implementing the remediation plan for web app risks, it's not enough to assume that your web application security is now impervious to threats. You need to verify that the security risks have truly been fixed. This involves retesting the application to check that the code changes are effective and have not introduced new security issues.

    This will help you to confirm that your security posture has improved and doesn't affect the functionality of your website.

    Step 5: Monitoring & Maintenance

    Web application protection is not a one-time affair; it's an ongoing process. To ensure web application security, you must continuously monitor them for security issues and threats, while responding to any new emerging threats.

    Regular updates and security patches are vital for maintaining a secure web application. Furthermore, proactive monitoring can help detect new vulnerabilities, allowing you to take action promptly.

    These five critical steps of vulnerability management, from identification to ongoing monitoring and maintenance, provide a strategic roadmap for organizations that protects applications against potential attacks and maintains a resilient web application security posture.

    Whether you're safeguarding your SaaS platform or want a safer online experience, implementing web application security protocols that include automated testing tools for security scanning for broken access control is crucial towards improving security for your applications.
