What is RASP?

RASP stands for Runtime Application Self-Protection. It's a security technology that works from inside your application to protect it against attacks in real-time.

Basic concepts

RASP is like having a security guard living inside your app. This guard:

• Watches everything that happens in the app
• Checks all inputs and outputs
• Keeps an eye on the app's internal state

When RASP spots something fishy, it can take action right away. This could mean blocking an attack, alerting the security team, or even shutting down the app if needed.

Main features

RASP has some key features that set it apart from other security tools:

• Deep visibility: RASP sees everything happening inside the app. This means it can spot a wider range of potential attacks.

• Context awareness: RASP understands how the app works. This helps it tell the difference between normal behavior and actual threats.

• Zero-day protection: RASP can catch new, unknown attacks by spotting unusual behavior.

• Low false positives: Because RASP knows the app so well, it's less likely to raise false alarms.

• Easy deployment: RASP is designed to be simple to add to existing apps.

Here's a quick look at how RASP compares to a traditional Web Application Firewall (WAF):

RASP isn't just for web apps. It can work with different types of applications, including those using XML or RPC standards. It's also a good fit for cloud apps, providing strong security that moves with your app.

For developers, RASP fits nicely into modern DevOps practices. You can add it to your continuous integration and deployment (CI/CD) pipeline, making security a natural part of your development process.

How RASP works

RASP operates by embedding itself directly into your application's runtime environment. This unique approach allows it to monitor and protect your app in real-time, without needing to alter your existing code.

Adding RASP to apps

Implementing RASP is surprisingly straightforward:

1. Upload your app: Send your application to a RASP-enabled security build system.

2. Build protection: The system adds RASP features to prevent code tampering.

3. Certify: Verify the RASP functionality in your mobile app.

This process integrates RASP seamlessly, requiring no extra development work or delays in your release cycle.

Always-on protection

Once activated, RASP acts like a vigilant security guard inside your app. It:

• Watches all app activities
• Analyzes inputs and outputs
• Monitors the app's internal state

This constant surveillance allows RASP to spot and stop threats immediately, often before they can cause any damage.

Spotting unusual behavior

RASP's strength lies in its ability to detect anomalies. It does this by:

• Analyzing runtime behavior patterns
• Comparing current actions to known safe behaviors
• Identifying deviations that might signal an attack

For example, if RASP notices an unusual database query that looks like SQL injection, it can block the query before it reaches the database.

RASP vs. older security tools

Let's compare RASP to older security methods, like Web Application Firewalls (WAFs). While both aim to protect applications, they work quite differently.

RASP and WAF differences

RASP operates from inside your app, while WAFs work from the outside. Here's how they stack up:

WAFs act as the first line of defense, blocking common attacks. But RASP goes deeper, tackling complex threats that slip past WAFs.

RASP benefits

RASP shines in several areas:

• Real-time protection: RASP spots and stops threats as they happen.
• Context understanding: It knows how your app works, reducing false alarms.
• Zero-day defense: RASP can catch new, unknown attacks.

RASP vs. WAF table

Here's a quick look at how RASP and WAF compare:

While WAFs are easier to set up, RASP offers deeper protection. But here's the kicker: you don't have to choose. Using both creates a strong, layered defense.

"Over 180,000 attacks bypass WAFs every week but are successfully blocked by RASP solutions like Contrast Protect."

This stat shows why many companies now use both WAF and RASP. WAFs catch the obvious threats, while RASP handles the sneaky ones.

Main RASP benefits

RASP offers several key advantages that make it a powerful tool for application security. Let's explore these benefits:

Better threat detection

RASP excels at identifying threats in real-time. Unlike traditional security tools, RASP operates from within the application, giving it unparalleled visibility into runtime behavior. This inside view allows RASP to spot and stop attacks as they happen, even zero-day threats that might slip past other defenses.

For example, RASP can effectively address many of the OWASP Mobile Top 10 risks, including SQL injection and cross-site scripting (XSS). Its ability to analyze application behavior and trace inputs to their execution points leads to more accurate threat identification.

Fewer false alarms

One of RASP's standout features is its low rate of false positives. By understanding the application's inner workings, RASP can distinguish between genuine threats and harmless actions that might appear suspicious to other tools.

This precision is crucial for security teams. It reduces alert fatigue and allows them to focus on real issues rather than chasing down false leads. For instance, in a scenario where a user submits a name change request, RASP would analyze the input, trace it to the SQL execute command, and allow the request if it determines no actual threat exists.

Understanding app context

RASP's deep integration with the application gives it a unique advantage: context awareness. It uses a technique known as Language Theoretic Security (LangSec) to detect threats by understanding how the application will use incoming data.

This context-sensitive approach allows RASP to:

• Provide specific information about attacks down to the code level
• Identify true threats while ignoring benign actions
• Offer insights that can be used to improve software security continuously

Easy to add

Despite its sophisticated capabilities, RASP is designed for seamless integration into existing software setups. Developers can leverage SDKs or agents specifically designed for various platforms to add RASP to their applications.

RASP fits naturally into the DevOps model, making security part of the Continuous Integration / Continuous Delivery pipeline. It can protect both new and legacy applications without requiring significant changes to the codebase or development process.

Common RASP uses

RASP technology has found its place in various application security scenarios. Let's look at some common uses:

Protecting websites

RASP guards web apps from threats like SQL injection and cross-site scripting (XSS). It analyzes app behavior in real-time, stopping attacks as they happen.

For example, if a malicious user tries to inject SQL code into a login form, RASP can:

1. Detect the unusual input
2. Block the execution of the harmful code
3. Log the attempt for further analysis

This real-time protection helps keep websites safe from both known and unknown threats.

Securing APIs

APIs are often targets for attackers due to their direct access to backend systems. RASP improves API safety by:

• Monitoring API calls for unusual patterns
• Blocking requests that could lead to data breaches
• Providing insights into API usage and potential vulnerabilities

Cloud app security

Cloud apps face unique security challenges. RASP helps by:

• Providing portable security that moves with the app
• Offering protection regardless of the underlying infrastructure
• Adapting to dynamic cloud environments

RASP's ability to secure cloud apps without relying on network-level controls makes it a good fit for modern cloud architectures.

Older app protection

Legacy apps often lack modern security features. RASP can protect these apps without changing their code. This is helpful for organizations with:

• Apps that can't be easily updated
• Systems running on outdated platforms
• Limited resources for app rewrites
