Unveiling the Importance of Security Testing in OutSystems Applications
In an era where digital landscapes are battlegrounds, security, and cyber attacks have emerged as pivotal themes. Think of it as modern warfare without gunfire but with equally significant consequences. This unseen battlefront is critical yet shrouded in a veil of mystery with much left to discover and understand.
This article aims to shed light on the crucial role of security testing in applications, emphasizing those developed using OutSystems. We'll explore why it's essential to prioritize these tests in an environment where digital threats are both ever-present and continually evolving.
Understanding Cyber Attacks and the Underlying Motives
A cyber attack is an illicit endeavor by hackers to gain unauthorized entry into a system or network. Their goal? To disrupt, disable, modify, corrupt, seize control, or steal sensitive data. These attacks meticulously target data integrity and often aim to expropriate controlled information.
It all starts stealthily with random attacks across different industries or companies. Hackers or programmed computers scour for weaknesses, exploiting even the smallest system vulnerabilities. Once they identify vulnerabilities, the attacks intensify, burrowing deeper into the network. The end game is usually monetary gain – either through ransom demands from the affected entities or by selling the stolen information.
Sometimes, an attack is detected only a long time after the damage to the infrastructure has been inflicted.
So, what kind of information holds value for cybercriminals? Usually, they steal confidential data, intellectual property, or prototypes of potential products to sell or leverage for ransomware.
OutSystems applications, often central to data management, are likely targets; therefore, particular attention is needed to shield company and customer data.
Internal vs. External Applications: Navigating Security Landscapes
An internal application is confined within a specific domain and is accessible only to users within that domain. While the security risks in such applications are relatively lower, it is essential to remember that this does not make the servers hosting these applications immune to cyber attacks.
Common security breaches in internal applications include unauthorized system or network access, which could occur through hacking or the unauthorized use of account credentials.
Conversely, an external application is accessible to users outside the domain, thus introducing a higher number of vulnerabilities and requiring heightened security measures.
The accompanying image provides a standard schematic of the architecture recommended for different user types. While this architecture does not protect against all risks and vulnerabilities, it delineates the security considerations for internal and external users.
In terms of security measures, firewalls play a crucial role. They identify and filter out the 'DNA' of malware from incoming data packets, thus preventing malicious assembly within systems. On the other hand, Secure Web Gateways (SWGs) operate at the application layer. They are designed to block access to dangerous websites and applications, providing an additional digital domain security layer.

Vulnerability Scanning: A Key to Cybersecurity
Vulnerability scanning is a crucial automated process to identify application, network, and security infrastructure weaknesses proactively. This process is often conducted by third-party security service providers or an organization's IT department. Interestingly, vulnerability scans are also sometimes executed by hackers seeking network entry points.
The core of vulnerability scanning lies in identifying and categorizing system vulnerabilities within communication equipment, networks, and computers. Beyond pinpointing security loopholes, this process also evaluates the necessary countermeasures to thwart potential attacks effectively.
Internal Vulnerability Scanning involves conducting scans from within the internal network. These scans, predominantly performed within the internal network environment, offer in-depth insights into security vulnerabilities. The benefits of internal scans are manifold, providing a proactive defense against various known and unknown threats.
On the other hand, External Vulnerability Scanning, or perimeter scanning, is carried out from outside the network. This type of scan is instrumental in detecting vulnerabilities that pose a risk to assets exposed to the external world, namely the internet. By targeting external IP addresses, external scans reveal potential vulnerabilities and enumerate ports that are openly accessible to the internet, offering a comprehensive view of network security.

Navigating the Threat Landscape: Most Common Cyber-Attacks
Cyber-attacks come in various forms; thus, awareness of what they entail is vital for effective cybersecurity. Here's an overview of the predominant threats:
Phishing
This attack involves hackers sending fraudulent messages to trick victims into revealing sensitive information or installing malicious software. Typically, these messages impersonate reputable brands or entities, misleading the victim into believing they are genuine.
Malware
This term encompasses various types of malicious software, including viruses, worms, trojan horses, Ransomware, spyware, adware, and more. The primary purpose of malware is to infiltrate, damage, or disrupt computers, servers, or networks. While financial ransom is a common motive, especially with Ransomware, malware can also be used to gain unauthorized access to systems, steal sensitive data, or cause disruption and damage without a financial motive. The broad range of malicious intents and types makes malware a particularly pervasive and dangerous cyber threat.
Brute Force
This attack strategy forces entry into a system, site, or server by attempting thousands of possible passwords, user logins, and encryption keys in hopes of finding the correct one to gain full access.
Man-in-the-Middle
As the name suggests, this attack occurs when a hacker intercepts communication between two servers, computers, or systems, potentially impersonating one of the communicating parties to capture confidential information.

Addressing Common Vulnerabilities in OutSystems
Understanding and mitigating common vulnerabilities is crucial in web and application development. Here's how OutSystems effectively addresses these issues:
Broken Access Control
Access control issues occur when attackers can access, modify, delete, or perform unauthorized actions in an application.
The OutSystems platform has this vulnerability protected by implementing role-based access control. Therefore, an administrator defines the roles of specific users and their permissions, so the application is expected to be only reachable by the right people and with the proper responsibilities.

Insecure Design
This vulnerability stems from the absence of integrated security controls throughout the application's development cycle.
OutSystems security checks proactively warn developers of potential security issues as they publish their applications.
Security Misconfiguration
This issue is a vulnerability when different rules are defined in various places for the same component or when the rules are poorly defined, set to default, or even non-existent. Some scenarios are, for example, using accounts/passwords that are already set by default, the software is outdated, flaws are not fixed, a secure password policy is not implemented, files and directories are unprotected, blocklists and allowlists to block or allow some targets, and many other cases.
OutSystems provides system administrators with clear and concise instructions on how to make the platform installation secure. In addition, it includes a set of capabilities that allow you to define and implement the security controls required by your applications.
