In the last decade, mobile security technology has gained traction to counter cyber threats in the industry. Mobile technologies such as cell phones, tablets are heavily used to surf the web, run apps, read email, post to social media, conduct financial & banking transactions, etc. There has been a tremendous surge in the use of mobile devices for both personal and business uses. The advent of mobile devices and the proliferation of mobile applications have facilitated mobility on a large scale. Because of this, concerns have arisen about the issues of preserving security when traveling across the digital realm.

According to Statista’s report, there are 6.378 billion-plus mobile phone users in the globe- comprising 95% of the entire world's population.

With cases of frequent user privacy breaches, mobile device security continues to grow in importance. Although businesses are concerned about mobile security and data privacy, the use of applications from the internet causes serious problems in terms of addressing threats and vulnerabilities while securing a user's data privacy. Most software apps are built to do a certain activity and are aimed at a specific set of devices, such as smartphones and tablets. Mobile device data protection is a risky endeavor due to the various threats and vulnerabilities involved.

Difficulties with Mobile Device Security

The mobile market is growing as wireless technology advances and mobile device usage improves. The growth in the development and maintenance of secure identities for mobile devices has created a huge challenge for individuals, society, and businesses, particularly in mobile added-value services such as mobile banking, and mobile ticketing. The following are a few of the most notable difficulties with mobile devices as a result of threats and vulnerabilities.

Sensitive Data & Information leaks

When sensitive data and information such as password credentials, secret keys, access tokens, sensitive business logic, are defined/hardcoded into the application code, it opens the door for an attacker to discover this information by reverse engineering it. Once such information is in the hands of an attacker, the situation might become very chaotic.

Unguarded Data Storage

General non-encryption, caching of information that is not intended for long-term storage, and a lack of platform best practices can lead to exposure of sensitive information.

Weak Authentication and Authorization

When it comes to security, weak authorization and authentication techniques that depend on device-identifiers such as the International Mobile Equipment Identity (IMEI) and universally unique identifier (UUID) values are a perfect recipe for disaster.

Server-Side Control

On the backend side, failure to apply effective security measures like patches/updates & secure configs can result in a massive data breach.

Brute Force Attack

There are several mobile applications today that use password-based authentication as single-factor authentication. Because of this, the proprietors of these programs don't enforce strong passwords or the protection of valuable credentials. User's credentials can be stolen, and automated brute force assaults can be launched against them.

Improper Session Handling

Session handling has been flagged as a security problem for web applications on mobile devices. When using internet apps on any platform, such as mobile devices or PCs, improper session handling creates risks. When executing financial transactions, sessions with long expiry durations create vulnerabilities. Such session hijacking on mobile devices can be traced back to poor session management.

Lack of Transport Layer Protection

In mobile applications, it is common to see no encryption for sent data. However, disregarding certificate validation issues or reverting to plain text communication after failures can put security in peril and have significant consequences such as data tampering and can even encourage man-in-the-middle attacks if they are not addressed immediately.

Client-Side Injection

On mobile devices, malicious applications are executed via application or web browsing client-side injections. Client-side injections can take the form of HTML injections or SQL injections. It's possible for hackers to launch a text-based assault and take advantage of a targeted user. By using this method hackers can inject any data source, including resource-targeted files or software, into the system.
