Users can see data that is not theirs
Changing an ID in a web address or API request shows another customer's order or invoice because the system does not check ownership.

Application Security Engineering for Web Apps, APIs and Business Systems
RDS Innovations helps make the software you build and run harder to misuse. We focus on application security engineering: how users log in, what each role can see and do, how APIs check requests, how passwords and keys are stored, and how deployments are configured. We are not a certified penetration testing or audit firm, and we say so plainly.
- Security review of a web application
- Authentication improvements
- Role-based access control
- API security
IN PLAIN LANGUAGE
Application Security, explained simply.
Many security problems in business software come from ordinary development choices rather than sophisticated attacks. A page that checks whether a user is logged in but not whether they own the record they are viewing. An API key committed to a code repository. A form that trusts whatever is typed into it. An outdated library with a known weakness. Application security engineering is the work of finding and fixing these issues, and building habits that prevent them.
Our work covers secure development practices, authentication (confirming who a user is) and authorization (deciding what they are allowed to do), API security, input validation, secrets handling, dependency updates and hardening of the servers and containers your application runs on. This can be part of a new build, or a focused security review of an existing web application followed by fixes.
We are clear about scope. RDS Innovations is not positioned as a certified penetration testing or security audit firm. Formal penetration tests, compliance audits and certifications are separate engagements carried out by specialist providers. We can help you prepare for them, answer technical questions during them and fix the findings they report.
PROBLEMS IT SOLVES
Why businesses invest in it.
Everyone has admin access
Staff share one login or all have full permissions, so there is no way to limit mistakes or tell who changed what.
Passwords and keys in the wrong places
Database passwords and payment API keys sit in code, shared documents or chat messages, and old keys are never rotated.
Outdated libraries and servers
The application depends on packages and server software that have not been updated in a long time, including versions with publicly known weaknesses.
A customer or partner asks about security
A larger client sends a security questionnaire, and nobody can confidently answer how access, data and updates are handled.
IS IT RIGHT FOR YOU?
Who needs it, and when.
Who it is for
- Businesses running customer portals, admin panels or business systems with sensitive data
- SaaS products preparing for larger customers who ask security questions
- Teams that inherited an application and are unsure how secure it is
- Organizations building new software that want security considered from the start
When it is the right time
- Your application stores personal, financial or business-confidential data
- You are adding user roles, a public API or external partner access
- A security questionnaire, incident or near miss has raised concerns
- You are preparing for an independent penetration test or audit and want to fix obvious issues first
WHAT'S INCLUDED
Features, deliverables and capabilities.
Scope is agreed in writing for every project. These are the building blocks we typically plan with you.
Security review of a web application
A structured review of code, configuration and key user journeys, with findings ranked by risk and explained in plain language.
Authentication improvements
Secure password storage, login rate limiting, session handling, password reset flows and optional two-factor authentication or single sign-on.
Role-based access control
Roles and permissions designed around real job functions, with checks enforced on the server for every screen, record and API action.
API security
Authentication for every endpoint, ownership checks, rate limits, careful error messages and verification of incoming webhooks.
Input validation and safe data handling
Validation of form and API input, protection against common injection and scripting attacks, and safe handling of file uploads.
Secrets handling and dependency updates
Moving keys and passwords into secure configuration, rotating exposed ones, and setting up a routine for library and framework updates.
Deployment hardening
HTTPS everywhere, security headers, restricted server and database access, minimal container images and logging of security-relevant events.
USE CASES
How businesses use it.
Representative examples of the work, described generically. They are not client case studies.
Customer portal ownership checks
A portal is reviewed so every order, invoice and document request checks that the logged-in customer actually owns that record.
Admin panel role redesign
A single all-powerful admin login is replaced with roles such as support, finance and manager, each limited to the actions their job needs.
Exposed key clean-up
API keys found in a code repository are rotated, moved into secure configuration and removed from the code history where practical.
Pre-audit preparation
Before a client's independent penetration test, common issues are fixed so the formal test can focus on deeper findings.
Fixing third-party audit findings
Findings from a specialist provider's report are prioritized, fixed and documented, ready for that provider to retest.
DELIVERY PROCESS
How we deliver it.
Decisions stay visible, important workflows are validated early, and delivery is shaped around the agreed scope.
- 01
Understand what needs protecting
Identify the sensitive data, user types, entry points and external connections, and agree on the scope of the review.
- 02
Review code and configuration
Check authentication, permissions, API handling, validation, secrets, dependencies and server settings against the agreed scope.
- 03
Rank findings and agree fixes
Present findings by risk and effort, and agree which to fix now, which to schedule and which to accept with clear reasons.
- 04
Implement and verify
Apply fixes, add tests where possible so issues do not return, and recheck each finding after the change.
- 05
Document and recommend next steps
Record what was reviewed, what changed and what remains, including when an independent penetration test is advisable.

PLANNING
Considerations, cost and timeline.
Limitations & implementation considerations
- RDS Innovations is not a certified penetration testing or audit firm. Formal penetration tests, compliance audits and certifications should be carried out by specialist providers.
- No review can find every possible weakness. Security work reduces risk but cannot remove it, and needs ongoing attention as software and threats change.
- Legal and regulatory obligations, including under India's Digital Personal Data Protection Act, 2023, must be assessed with your legal advisers. We can implement technical measures they recommend.
- Some fixes affect user experience, such as stronger login steps, and need agreement from the business before rollout.
What affects cost
- Size of the application and number of user roles
- Number of APIs and external integrations
- Condition of the codebase and how outdated its dependencies are
- Whether fixes are included or only the review
- Hosting and deployment complexity
Typical timeline
A focused security review of a single web application typically takes one to a few weeks, depending on its size. Fixes are then scheduled by priority, with high-risk items addressed first.

FAQ
Questions about app security.
Do you provide penetration testing or security certification?
No. RDS Innovations is not positioned as a certified penetration testing or audit firm. We focus on secure engineering and reviews from a developer's perspective, and we recommend a specialist provider when you need a formal test, audit or certificate.
Can you fix issues found in an external security audit?
Yes. We can review the audit report, prioritize the findings with you, implement fixes in the application and infrastructure, and document the changes so the auditing provider can retest.
What is role-based access control?
It means permissions are attached to roles, such as sales, accounts or manager, rather than set individually for each person. Users get a role that matches their job, and the system checks that role on every action. It makes access easier to manage and review.
Will security work make our application slower or harder to use?
Most measures, like server-side permission checks and validation, are invisible to users. Some, like two-factor login, add a step. We discuss these trade-offs with you and apply them where the risk justifies it.
Can you make our application compliant with data protection law?
We do not certify compliance. Your legal advisers should assess your obligations, including under India's Digital Personal Data Protection Act, 2023. We can then implement the technical measures they recommend, such as access controls, data retention rules and consent records.
