Application Security Engineer: What You Need to Know

Today, applications are used across various aspects of life, from social media to industries. This widespread use has created a need for implementing security measures for these programs. One of the professionals responsible for this is the Application Security Engineer. 

In this article, we will cover the most important aspects of the engineer job for an application security engineer. In addition to discussing their functions, we will analyze the skills and knowledge required to successfully fulfill their responsibilities.

Role Description of an Application Security Engineer 

As the job title suggests, an application security engineer is responsible for protecting applications and computer systems. To ensure security in these programs, they must identify risks, evaluate them, and implement measures to mitigate them. 

The engineer’s job begins right from the application development process. Therefore, they must ensure that the design and development incorporate security measures that can withstand potential attacks and help the apps recover from them. 

From the above, we can say that the work of application security engineers is closely related to that of software developers. The functions of both professionals complement each other to ensure that the creation, launch, and operation of applications are characterized by security. 

Functions of an Application Security Engineer 

Given the role's objective, the functions of an application security engineer must ensure the professional contributes to the protection of information security within an application. The responsibilities of this engineer include the following: 

Identification of Security Vulnerabilities 

In most cases, the first step for application security engineers is to identify vulnerabilities in software. To detect these, specialized techniques are used to uncover security flaws that could be exploited by cybercriminals. 

The methodologies used by application security engineers to fulfill this function include static code analysis, configuration reviews, and program scanning. The goal of this function is the early identification of security vulnerabilities to prevent attacks. 

Risk Assessment 

After identifying the vulnerabilities, it is crucial to evaluate the risks they represent. To do this, dynamic testing can be conducted to analyze the severity of the vulnerabilities and determine how they would impact both the application itself and the organization as a whole. 

Risk assessment enables the engineer to determine the best corrective actions and prioritize them. Additionally, it allows them to develop an effective strategy for mitigating the risks. 

Implementation of Security Measures 

To fulfill this function, it is necessary to adhere to the previously described steps. Once vulnerabilities are identified and their risks are assessed, security measures can be designed and implemented to mitigate potential issues throughout the software development lifecycle. 

When completing this function, it is necessary to carry out additional tasks that affect the efficiency of implementing security measures. These tasks include applying patches, configuring supplementary security controls, and even modifying the application's architecture. 

Code Review and Penetration Testing 

To ensure that security measures are maintained throughout the application development process, it is essential to review the code. To fulfill this role, the application security engineer must analyze the code in detail, identifying aspects such as: 

• Unsafe practices 

• Lack of entry-level validation 

• Inadequate handling of sensitive information 

It is also necessary to conduct security testing focused on penetration, where attacks are simulated. This way, the methods by which cyber attackers might exploit vulnerabilities in an application are identified. 

Education and Training for Company Staff 

Unlike the previous functions, the presentation of this role varies from one organization to another. In some companies, application security engineers are asked to train team members in security practices. This training helps foster a culture of security within the company. 

What Education is Needed to Become an Application Security Engineer? 

The academic training required for this type of engineer must provide a solid and professional foundation. It should include not only technical knowledge but also preparation to help students face the challenges of this role once they are working professionally.  

The foundation of the education received by an application security engineer should be a university degree related to computer science and technology. Common degrees in this profession include Computer Engineering, Information Systems, and Data Science. 

If your university education is complemented by a professional certification, your profile will be more attractive to recruiters. Some of the most recognized and relevant certifications in this field are CISSP, CEH, and OSCP. 

The career in application security is worthwhile! 

Those considering academic preparation to become application security engineers should know that it is a highly valuable profession. Moreover, the technology sector is constantly growing, so there is no doubt that this career has a bright future. 

In application security engineering, professionals face exciting and challenging opportunities while fulfilling a key role. This role focuses on protecting systems that are fundamental in the digital age we live in.
