WHAT'S CHANGING
Application Risk Is Moving With the Technology
Modern applications are distributed acrossdevelopment pipelines, APIs, cloud environments, identities, and runtimeinfrastructure. Security therefore has to move beyond traditional applicationtesting and address risk throughout how applications are built, connected,deployed, and operated.
01
Shift-Left Security
Securitytesting and controls move earlier into development.
02
API Security
Protect the interfaces that connect applications, systems, and services.
03
Cloud-Native Application Security
Extend application protection across containers, microservices, and cloud-native architectures.
04
Zero Trust Application Access
Apply identity- and context-based controls rather than assuming trusted access.
05
Continuous Security Testing
Validate security continuously as applications and code change.
06
Runtime Application Protection
Detect and respond to threats while applications are running.
07
AI-Driven Application Security
Use AI-assisted analysis and automation to improve vulnerability discovery, detection, and response.
WHY THESE SHIFTS MATTER
Security That Keeps Pace With Application Change
As applications evolve across development, cloud, APIs, and runtime environments, security needs to evolve with them. These approaches help organizations reduce exposure, strengthen protection, and maintain security without slowing application delivery.
02
API Protection & Mobile App Security
Protect the Connections Behind Your Applications
APIs and mobile applications extend your digital environment beyond the application itself. They connect users, systems,services, and sensitive data—creating additional paths that need to be secured. Netrust helps organizations protect these connections with controls for identity, data, application integrity, threat detection, and continuous monitoring.
SIX SECURITY PRIORITIES
Protect Every Connection and Interaction
01
Authentication and Authorization
Control who can access your applications and APIs.
Strengthen identity verification and enforce appropriate permissions to reduce unauthorized access and privilege abuse.
02
Data Encryption
Keep sensitive data protected wherever it moves.
Encrypt data in transit and at rest to reduce exposure if communications or application environments are compromised.
03
Threat Detection
Detect suspicious activity before it becomes a larger incident.
Identify abnormal requests, attack patterns, and malicious behavior across APIs and mobile applications.
04
Secure Coding Practices
Build security into the application from the start.
Apply secure development practices to reduce vulnerabilities before code reaches production.
05
Monitoring and Logging
Maintain visibility across application activity.
Monitor requests, events, and user activity to detect anomalies, investigate incidents, and support faster response.
06
App Integrity Protection
Make sure applications haven't been altered or compromised.
Protect application code and mobile binaries against tampering, reverse engineering, and unauthorized modification.
HOW PROTECTION IS APPLIED
ProtectionThat Works Across Every Request
Every interaction is evaluated through multiplesecurity controls—from access and encryption to validation, monitoring, and response—helping prevent malicious activity from reaching applications or sensitive data.
01
Access Control
Verify before granting access.
Authenticate users and applications and enforce appropriate permissions before they can reach APIs or mobile applications.
02
Secure Communication
Protect data while it moves.
Encrypt communications to reduce the risk of interception or exposure.
03
Request Validation
Stop malicious input at the entry point.
Validate API requests and application inputs to detect and block malicious or unexpected content.
04
Continuous Monitoring
Maintain visibility as activity happens.
Monitor requests, usage, and behavior to identify anomalies and emerging threats.
05
Threat Response
Act when suspicious activity is detected.
Block, contain, or flag suspicious activity for investigation and response.
REQUEST VERIFIED
Every Request, Protected at Every Layer.
Access control, encryption, validation, monitoring, and response work together to reduce exposure.
SECURITY BUILT INTO EVERY INTERACTION
Strong identity, protected data, secure development, and continuous visibility work together to reduce application exposure.
IMPLEMENTATION PRIORITIES
Build Protection Into Every Layer
Effective API and mobile app security combines strong identity controls, protected communications, secure development, and continuous visibility. The goal is to reduce exploitable paths while keeping applications usable and resilient.
01
Strengthen Identity & Access
Verify every user, application, and request.
Use strong authentication such as OAuth, secure tokens, and MFA, while applying least-privilege access to limit what each identity can reach.
02
Protect Data & Communications
Keep sensitive information protected wherever it moves or resides.
Use HTTPS/TLS for data in transit and appropriate encryption for sensitive data stored on devices, servers, and application environments.
03
Validate & Control Application Traffic
Prevent malicious input and abusive requests from reaching your applications.
Validate API requests and user inputs, secure API keys, and apply rate limiting to reduce abuse and denial-of-service risks.
04

Address vulnerabilities before they reach production.
Apply secure coding practices, code reviews, vulnerability scanning, and penetration testing throughout the application lifecycle.
05
Maintain Visibility & Respond
Know what your applications are doing and act when behavior changes.
Monitor and log API activity and application behavior to detect suspicious activity, investigate incidents, and support timely response.
06
Secure API Keys
Avoid hardcoding keys in mobile apps. Store them securely and rotate them regularly.
07
Use Secure Coding Practices
Regularly test and review code to prevent vulnerabilities.
08
Monitor and Log Activity
Track API usage and app behavior to quickly detect suspicious actions.
09
Regular Security Testing
Perform penetration testing and vulnerability scans to identify weaknesses.
COMMON THREATS
Where Application Exposure Begins
Attackers typically look for weaknesses in identity, data protection, API controls, and application interfaces. These gaps can provide unauthorized access, expose sensitive information, or be used to disrupt services.
01
Weak Authentication
Weak or poorly implemented authentication can allow attackers to bypass access controls and compromise accounts.
02
Data Exposure
Insufficient encryption or protection can expose sensitive information in transit, storage, or application workflows.
03
API Abuse
Excessive, automated, or malicious requests can exploit APIs, consume resources, or disrupt services.
04
Insecure API Endpoints
Poorly protected API endpoints can expose functions or data to unauthorized users and applications.
COMMON USE CASES
Where API & Mobile Protection Matters
01
Digital Banking & Financial Services
Protect transactions, credentials, and sensitive financial data across mobile and API-driven services.
02
Web & mobile APIs
Secure the interfaces connecting applications,users, systems, and third-party services.
03
Sensitive Data Flows
Protect data as it moves between applications, APIs, devices, and backend systems.
04
Application to Backend Connections
Secure communication between mobile or web applications and the systems behind them.
05
CreIdentity & Credential Protection
Protect authentication data and user credentials from theft, exposure, and misuse.
WHY IT MATTERS
Secure the Connections That Keep Your Applications Moving
APIs and mobile applications extend your securityboundary beyond the application itself. Protecting the connections, identities, data, and interactions behind them helps reduce exposure, prevent abuse, and keep digital services secure as they scale and evolve.
