Ground zero of mobile app security

Why is mobile application security important?

Before we dive into the technical deets, let's start by asking the fundamental question:

Why is mobile application security important for your organization?

This is as straightforward as it gets: neglect mobile app security, and you're essentially leaving your organization's digital assets unguarded, available for the taking by cyber bullies. 

Today, it's not a matter of 'if' but 'when' your vulnerabilities will be exploited. 

The consequences? Stolen sensitive data, financial devastation, and a tarnished reputation that's often impossible to fully recover. 


Understanding the risk factors associated with mobile app vulnerabilities

Consider mobile app vulnerabilities as the unlocked doors in a building. They provide the opportunity that attackers seek. But understanding these risks is the first step to defending against them. To put it in the words of Mike Assante, a renowned cybersecurity expert: "The cost of securing a system is inversely proportional to the cost of a breach."


Key players in mobile appsec

It's a collaborative effort, with the CISO leading the charge, the CTO, and security experts working together to fortify your organization's defenses. While these security leaders may lay the groundwork, the responsibility of 'who stands guard' responsibility extends to every team member. 

Consider a scenario where a team member, unaware of security best practices, unknowingly introduces mobile app vulnerabilities during a rushed development phase. These vulnerabilities may go unnoticed within the organization until a vigilant hacker seizes the opportunity to exploit them. 


The changing face of mobile app security — then vs. now

A. Historical perspective: lessons from the past

In the early days of mobile app development, security was often an afterthought. Developers focused more on functionality and aesthetics, often leaving vulnerabilities wide open. This laid the groundwork for the first wave of security breaches, where hackers exploited these weaknesses with relative ease.

Learning from these past incidents, the mobile app security landscape underwent a significant transformation. Organizations began recognizing the importance of robust security measures and mobile app vulnerability assessments. Encryption, authentication, and authorization became standard practices. The adoption of secure coding and regular security audits also gained momentum.


B. Current state of mobile app security: navigating modern challenges

Fast forward to the present, and the mobile app security landscape has witnessed dramatic changes. Emerging trends and challenges continually shape our approach to safeguarding our digital assets.

The current state of mobile app security is marked by a dynamic interplay of factors. The rise of remote work and the bring-your-own-device (BYOD) trend have expanded the attack surface, making device and data protection more complex. Moreover, the ever-evolving threat landscape keeps mobile app security teams on their toes.

Regulatory requirements have also left a lasting mark. Regulations like GDPR and CCPA have compelled organizations to prioritize data protection and user privacy within their mobile apps. Compliance has become not just a matter of legal adherence but a symbol of trust and accountability in the eyes of consumers.

Mobile application security - the Achilles' heel of modern businesses

As businesses are evolving, the very technology that fuels their progress is becoming a source of vulnerability. Thus, in their ubiquity as the catalysts of efficiency and innovation, mobile apps are also the Achilles' heel of modern business, where vulnerability and necessity intertwine.

This isn't exclusive to a single industry or sector. Look at the examples of these industries, for instance:

Protecting your most valuable asset — data

Your organization's most valuable asset is not the physical infrastructure or the intellectual property locked away in vaults. It's the data – the lifeblood of your operations, the key to your customer trust, and the target of insatiable cyber threats. You need to implement stringent mobile app security measures to protect your business from data and application vulnerabilities.

How to protect your data through data encryption?

One of these would be data encryption.

Where data is gold, encryption acts as the Fort Knox – an impenetrable fortress protecting your digital treasures. It's not just a precaution; it's an absolute necessity. Data encryption ensures that even if your mobile app's security is compromised, the data within remains a jigsaw puzzle for unauthorized access. It's the digital equivalent of sealing your data in an unbreakable safe.

Another one might sound like a saying, “Trust but verify." Authentication and authorization are the gatekeepers of your digital space. Robust authentication ensures only authorized users access your mobile app, while fine-grained authorization controls who can access what.

However, how can you guarantee comprehensive app security coverage beyond these fundamental practices? Let's delve into the five essential pillars that leave no room for security gaps and help you fulfill all security requisites.

But what are the other benefits of mobile app security?

Paying heed to mobile app security in your development phase lets you resolve security issues early, enabling you to cut down on unwanted disruption in operations. Besides, you don’t need to worry about spending extra bucks on recovering from cyber attacks or fixing the loose ends of your security framework.

So, to sum up, mobile app security is much more than mitigating the immediate threats. Investing in app security has a ripple effect as it positively impacts your business’s operations, reputation, and relationships with your customers and stakeholders. 


Building a business-grade mobile app security strategy - 5 key areas

A holistic security strategy against mobile app vulnerabilities is imperative for the complete protection of your business growth. While it comprises numerous intricate elements, here's a concise checklist of five pillars to kick-start your efforts.

How to protect your data through data encryption?

1. Mobile app security testing & continuous monitoring

A. Automated app vulnerability scanner tools for known vulnerabilities

Automated mobile app scanning tools play a pivotal role in maintaining robust business security. They assess your security posture, especially for known vulnerabilities. This includes Static Application Security Testing (SAST) to scrutinize the code, Dynamic Application Security Testing (DAST) to test the running app, and API testing to ensure secure data exchange. 

Additionally, Software Bill of Materials (SBOM) is an indispensable security solution that tracks every component within your mobile apps. It empowers you to stay ahead of potential exploits, maintaining a secured mobile application.

B. Penetration testing for unknown vulnerabilities

Penetration testing is the digital stress test, simulating real-world attacks to uncover the hidden weak links in your security chain. Pentesters specifically target unknown vulnerabilities, making it a crucial component in your mobile app security strategy.

C. Continous monitoring

Additional solutions, such as store monitoring, help security managers ensure that only tested and secured versions of applications go online.


2. Safeguarding the mobile app ecosystem

A. Mobile Device Management (MDM) and Mobile Application Management (MAM)

MDM and MAM are responsible for ensuring that mobile devices used within your organization are secure. They help set up and enforce security policies on these devices, such as password requirements, data encryption, and remote wipe capabilities. These tools also help in enforcing policies related to app usage, data access, and device configurations. 


B. Third-party APIs and integrations

Many mobile applications integrate with third-party services or APIs to expand their functionality and offer additional features. These integrations can introduce potential risks, such as security vulnerabilities, data breaches, or privacy concerns, especially if the third-party service is not trustworthy or adequately secured.


3. Advanced mobile app security strategies

A. Secure mobile app development lifecycle (shift-left approach)

In traditional development approaches, security might be considered an afterthought, but now, it's a fundamental component right from the beginning. This means that security measures are not added on as a patch but are built into the app's architecture, design, and development stages. This is the shift-left movement from DevOps to DevSecOps. 


B. Runtime Application Self-Protection (RASP)

RASP can detect and respond to security threats in real time, preventing attacks from causing harm before they even begin. It offers a level of protection that is impossible with traditional security measures that may only identify threats afterward. RASP understands the behavior of the application it protects. It can differentiate between normal operations and suspicious activities, allowing it to take appropriate action when an anomaly is detected.

It can defend against previously unknown or "zero-day" attacks because it focuses on abnormal behavior rather than relying on known attack signatures.

4. User education and awareness

User education and awareness are about ensuring that end-users are informed and equipped to make secure choices when using mobile apps. For instance, users are often targeted by phishing attempts, where malicious actors try to trick them into revealing sensitive information like passwords or personal data. Educating users on recognizing and avoiding phishing attempts helps prevent data breaches and unauthorized access.

Overall, it reduces the risk of human errors and promotes a culture of security, ultimately contributing to a safer mobile app ecosystem.


5. Road to recovery: mobile app security incident response

A. Crafting a mobile app security incident response plan

A well-crafted incident response plan is your shield against the potential fallout of a security breach. This plan should be tested and refined through simulations to ensure that your organization can effectively mitigate the impact of a security breach when it occurs.


B. Learning from mobile app security breaches

Post-incident analysis is not just a routine but a strategic necessity, offering crucial insights to elevate your security posture. Post-incident analysis aims to pinpoint the vulnerabilities and weaknesses in your mobile app security infrastructure that allowed the breach to occur. This goes beyond the immediate breach and extends to the overall security strategy.

Within the mobile app security niche, you'll find a wealth of case studies on real-world breaches. These cases, whether involving a major data breach at a financial institution or the exploitation of a vulnerability in a popular social media app, offer tangible examples of security measures faltering. Explore some of these recent data breaches in our blog.

Maximise ROI: strategic budgeting and resource allocation

Strategic budgeting and resource allocation

The ROI conundrum in mobile app security often presents a challenge for organizations. How can you achieve the highest level of protection for your digital assets without breaking the bank? 

Here, the fundamental principle is clear - you should invest wisely rather than extravagantly. You can consider the following:


1. Security investments against the potential cost of breach

A fundamental starting point is understanding the potential costs of a security breach.

● According to IBM's 2021 Cost of a Data Breach Report, the global average data breach cost was $4.24 million. 

● Violations of data protection regulations, like GDPR, can result in fines of up to €20 million or 4% of global annual turnover, whichever is higher.

With these figures in mind, let's do some calculations:

Suppose your organization has a yearly revenue of $100 million. A data breach that leads to regulatory penalties could result in a fine of $4 million. This alone would represent a 4% loss of annual revenue, not to mention the costs associated with the breach itself, the loss of business, and the legal expenses.


2. Resource allocation: build vs. buy

Building security solutions in-house can seem cost-effective but often involves significant hidden expenses. For instance, developing and maintaining proprietary security software may require a team of specialized experts, ongoing training, and constant updates to keep up with evolving threats.

In contrast, buying established security solutions can prove more efficient even with initial licensing costs. For instance, a security software license might cost $100,000 per year, while the equivalent in-house team's salaries, benefits, and ongoing training could easily exceed $500,000 annually.


3. Scalability and future-proofing

Consider the scalability of your chosen security solutions. Mobile app security requirements change over time, and what works today may not suffice in the future. For instance, investing in scalable cloud-based security solutions ensures you can adapt without extensive additional costs.


To conclude

As a business owner, you know the investment in time and resources that goes into building your mobile apps. Yet, it all hangs in the balance when the security of your creations is overlooked.

So, it is safer and wiser to invest in a more proactive approach to your mobile app security threats than a reactive one when the damage would already have been done.

Whether you're running a startup or steering the ship of a Fortune 500 business,  prioritizing and investing in mobile app security remains crucial. To ensure that every dollar invested in your mobile app security finds its best worth, we offer not just security but clarity.
