An act of negligence or error in handling the tiniest backend web application could lead to a security breach that jeopardizes your network. Understanding the dynamic of backend security risks, cyber attackers often target the backend of a network when they want to go for the kill.
Read on to discover the most common backend security risks and how to prevent them.
What Is Backend Security?
A standard web application has two parts—the front end and the backend. The front end is the part that’s visible to the public users of the application. The users get to browse and interact on the platform via the front end.
The backend, on the other hand, is where the server of the applications is. It contains the technical components that keep the application running.
A hitch on the backend of a network could render the network incapacitated. Hence, it’s important that you pay maximum attention to the backend of your web applications.
8 Backend Security Risks and Ways to Prevent Them
The backend of web applications has different layers that keep the server functional. Failing to configure, scan, or update any of these layers makes the system vulnerable to risks—an opportunity for cybercriminals to hack your system.
Let us examine some of the most popular backend security risks and what you can do to keep them away.
1. Data Injection
Data injection is the use of queries to hack your web application servers. Cyber attackers initiate a query to your system to retrieve sensitive data. In the absence of measures in place to check the origin and authenticity of the query, your system blindly processes the query and provides the requested information to the attackers.
A great way to prevent data injection is to ensure that your backend applications don’t accept or process inputs from unauthorized and unverified sources. That way, requests from unverified sources will be blocked or go unattended.
2. Access Control Misconfigurations
Access control levels (ACLs) help you to grant different categories of access to users of your web applications. Expectedly, members of your team should have more access to your web applications than the general users. Besides your team, no one has business accessing the sensitive data on your web applications.
Misconfigurations in your ACLs could cause unauthorized access to your system, allowing attackers to come in through windows that should have been locked. This backend security risk is common because people often overlook their ACLs.
To prevent access control-related risks, you need to constantly examine your ACLs to ensure that all parties using your web applications have the right level of access. Prioritize access to your most valuable assets to ward off intruders.
3. Software Misconfigurations
Activities on the front end of your web applications thrive on the functionality of your backend security. Misconfigurations on the backend could cause the front end to malfunction, thereby exposing your sensitive information.
For instance, an error message could pop up on the frontend when a component of your backend web application is down. The error message could contain sensitive information, such as data paths that will aid cybercriminals to hack your system.
Controlling the information displayed in error messages goes a long way in preventing risks from software misconfigurations. Optimize your backend operations, such as coding language and webserver, to block sensitive information from showing in pop-up messages.
4. Lack of Authentication
The components of your backend web applications have authentication requirements in the operating system. Similarly, their console/OS-level access and databases have login credentials in the operating system, too. The slightest vulnerability could expose all the components in the entire operating system to attacks.
Restricting logins to select users and IP addresses helps you to protect your authentication security. You can also deploy HTTP authentication to development areas and use automated systems to detect brute force attacks on your network.
5. Outdated Software Components
A web application is made up of several software components that keep it running. Each component plays a unique role in the successful operations of the web application. The vulnerability of a single component exposes other components in the application.
You need to prioritize the security of each component of your web application, as outdated or end-of-life software is highly prone to risks. Cyber attackers deploy advanced tools to search for outdated software online for their attacks. Ensure that all components of your web applications are updated to their latest versions to reduce their vulnerability to attacks.
6. Sensitive Data Exposure
In a bid to enhance the user experience on your website, your web applications may store some information or data generated by users in temporary locations. Access to such data is supposed to be restricted to the users in question. But, hackers could gain unauthorized access to the folder storing the information if it isn’t well-secured and use the data for their selfish gains.
7. Lack of Vulnerability Scanning
There might be vulnerabilities within your web applications that aren’t visible to you. Your network might be working just fine on the surface while certain risks lie underneath. If left unchecked, these risks could become fully blown to the detriment of your web applications.
Carrying out vulnerability scanning, frequently, helps you to detect any risks that may exist within your web applications.
Review the reports generated from your scanning to determine the safety of your web applications, and take necessary actions based on your findings.
8. Lack of Encryption Between Frontend and Backend Applications
The frontend and backend of your web applications may be on different sides but they work together to keep your web applications in motion. Encrypting the communications between both ends is overlooked sometimes.
Cyber attackers could steal or alter the communication between your frontend and backend with the use of man-in-the-middle attacks—a form of attack that enables spying on communications between two systems.
Leaving the communications between your frontend and backend web applications unencrypted is risky. For all you know, hackers might be spying or eavesdropping on your communications to steal sensitive data. Ensure that both ends are fully encrypted to resist man-in-the-middle attacks.
Prioritizing Your Backend Security Is the Way to Go
Your cybersecurity is only as strong as the measures you put in place to resist attacks.
As far as cybersecurity is concerned, it’s safer to acknowledge that your network is a target for attackers. Bearing this in mind spurs you to be proactive in securing your assets long before an attack manifests.
Prioritizing the backend of your web applications is in your best interest as well as that of your stakeholders because a security breach could cause damages that may be destructive to everyone.
