Cyber Security Facts App Developers Need to Know

Cyber security is a critical aspect of any app development project. It's important to understand the best practices for security before you start building your app and to maintain these practices throughout the lifecycle of your app's development.

One of the best ways to protect your app is by testing regularly. This can be done with emulators, threat modeling, and penetration testing.

XML Injection

XML Injection is a vulnerability that can allow an attacker to perform unauthorized actions within a web application. It occurs when an attacker injects malicious code into input fields that are used by a web application to process data. The code can be used to execute commands, expose sensitive data, or perform unauthorized actions on the system.

XML injection is a common security threat that can affect a wide range of applications, including web services and mobile applications. The level of damage an XML injection can cause depends on the information that is stored in a database and how that data is being used by the application.

The simplest way to protect against XML Injection is to make sure all user input is properly sanitized and validated. This will help prevent attackers from injecting XML tags, entities, and comments into the application’s input fields.

Another important step in protecting against XML Injection is to use parameterized queries instead of relying on raw input. Parameterized queries are safer because they eliminate the possibility of using raw input without any validation or sanitization.

This is because the raw input can contain any data that the application does not understand, allowing an attacker to inject malicious code into the query string and resulting XML document. This attack has the potential to reveal sensitive XML data, which could include passwords, credit card numbers, and more.

However, it is still crucial to sanitize user input and validate it before sending it to the server for processing. This will help to ensure that any XML Injection vulnerabilities aren’t able to occur in the first place.

XML External Entity Injection is a weakness in the way XML parsers handle XML documents that allow a reference to an external URI to be included in the document. This attack can be exploited to obtain information or access a system’s memory resources, which can lead to system compromise.

This type of vulnerability is commonly found in XML-based protocols, such as SOAP, and applications that process XML input. It can be exploited to gain access to a computer network, gather sensitive information, perform port scans, and more.

Code Injection

Code Injection is an exploitation technique where hackers exploit a software bug in order to inject malicious code into an application. This allows the attacker to gain access to restricted information and manipulate it in ways that they otherwise cannot.

It is important for app developers to understand what a Code Injection vulnerability looks like, and how it affects their application and users. This is important, as these vulnerabilities can be abused to execute arbitrary code, which can lead to serious consequences for users and their data.

There are a number of reasons for applications to be vulnerable to code injections. First, they may lack proper input validation or don't sanitize the data they store. Second, a user could be able to exploit an underlying security vulnerability in the third-party software or service used by the application.

One of the most common vulnerabilities that can occur in an application is Cross-site Scripting (XSS). This vulnerability happens when a web page accepts data from a user and includes it without properly validating or sanitizing the input.

Another common type of XSS vulnerability is Template Injection. This can happen when a web application replaces a template with unvalidated user input.

Injections also can be caused by developers using functions like eval() that interpret data as PHP codes. These functions are dangerous and should be avoided unless they are absolutely necessary.

If a developer must use these functions, it is best to restrict the use of these functions to specific types of user input. Some languages have built-in validation rules or packages, which can make this process much easier.

The most common way to prevent Code Injection is to make sure that all data is validated prior to processing it. This is especially true for file uploads, form fields, cookies, and query string parameters.

Finally, there are a variety of other ways to secure your application and mitigate this risk. Some of these include:

Object Deserialization

Deserialization is the process of converting a state of an object into a byte stream. This can be stored in a file, transferred over a network, or transmitted between processes on the same machine. It is an essential part of object persistence, which helps you re-create the same data when the user opens the app again.

In most modern applications, the state of an object is serialized and stored in a data store, such as a database or storage device. This allows the data to be retrieved when needed, for example when the application is started again or when a user leaves the game.

Objects can be serialized in a variety of ways, depending on the programming language. Some languages provide native support, while others use syntactic sugar or a standard interface to perform this encoding.

Java, for instance, has a default way of serializing objects; however, you can override this and define your own serialization method. This will allow you to control the way an object's state is serialized, and prevent it from being manipulated by other developers.

When serializing an object, you must ensure that all data members are also serializable. If an object does not have serializable data members, then the serialization will fail.

You can also prevent some data members from being serialized by marking them as transient. In this case, the value of these data members will not be included in the serialized state of an object when it is deserialized later on.

Another way of preventing insecure deserialization is to implement some type of object validation. This can be done by either blacklisting certain classes from being deserialized or by allowing objects of approved classes to be deserialized.

Insecure deserialization is a common security vulnerability in many types of websites and applications. It is a serious problem and can lead to a wide range of attacks, including remote code execution.

It is best to avoid deserializing user-controllable data from untrusted sources, as this can be dangerous for both users and your application. It can lead to exploits that are extremely difficult to block or defend against and can result in the loss of sensitive information.

Remote Code Execution

RCE, or remote code execution, is a type of vulnerability that allows an attacker to execute malicious code on a target device. These attacks are not only dangerous for users, but they can also wreak havoc on business operations.

As an app developer, you need to understand how to prevent this form of malware from affecting your customers. To do this, you need to learn about the different types of vulnerabilities that can lead to RCE.

One of the most common kinds of RCE attacks is exploiting a web server flaw. This flaw can allow an attacker to run a command on the website and potentially gain access to all of the user’s information and files on the site.

Another common form of RCE is the use of Trojan viruses, which allow criminals to remotely install malware on an individual’s computer. This malware can do everything from disabling parts of the operating system to holding data hostage until payment is made.

In order to avoid these threats, you need to keep your apps up-to-date with the latest patches and updates. In addition, you should ensure that you have a reliable network security solution in place.

When it comes to protecting your business and customers, cyber security is everyone’s responsibility. From C-suite executives to janitors, you have to make sure that you are taking all of the necessary steps to protect your company and the data you store.

A simple way to do this is by keeping your employees educated and informed about the latest threats and vulnerabilities. This will help them spot fraud, scams, and phishing.

For example, if an employee is browsing the Internet using an unsupported version of Windows XP, they could be exposed to an attack that will run a ransomware virus on their computer. This malware is set up by a criminal who has hacked the employee’s computer and will allow them to gain control of their files.

To prevent these attacks, it is important to update all your systems with the latest patches and updates from Microsoft. The company offers monthly patches to fix critical vulnerabilities that can lead to a successful RCE attack, so be sure to keep your business up-to-date on the latest patches to safeguard against this threat.
