APIs (Application Programming Interfaces) are deeply embedded in modern daily life. Connecting services like online operations, bank transactions, transportation apps and social networks, the security of APIs is a crucial aspect in the development and implementation of systems, since these interfaces are often targets of cyber attacks and vulnerabilities.
"APIs function as a gateway in companies", and that is why they must have a specific level of security. For being connection points between different applications and services, APIs can expose sensitive data and critical functionalities if not properly protected, comment Filipe Torqueto, Head of Solutions at Sensedia, global technology company reference in modern integration solutions based on APIs
According to the OWASP API Security Project report, developed by security specialists from around the world, among the most common vulnerabilities for APIs, unrestricted access to sensitive business flows; request forgery on the server; incorrect security configuration; inadequate inventory management and unsafe consumption of APIs. Another study, carried out by F5, global security and multicloud application delivery company, it raised that the average number of APIs managed by organizations is over 400, many of them with significant gaps in protection
To help minimize the risks of attacks, the executive of Sensedia lists 5 tips to ensure the protection of APIs in companies
1) Define Responsibilities
Normally, an API does not have a specific owner, and the responsibility for it can be shared among the team that developed it, the time that keeps it, or even a security team.
It is necessary to clearly define the roles and responsibilities of each one, even if this responsibility is shared among everyone. Furthermore, I recommend the use of some 'Guardrail', or 'protective barrier', fundamental to ensure safety, the efficiency and governance in the development and operation of these interfaces. They are guidelines and practices that help teams maintain safety and quality standards, minimizing risks and avoiding common mistakes, says Torqueto
2) Attention to good governance practices
Governance practices in the use of APIs are essential to ensure security, compliance and efficiency.
They establish clear guidelines that promote standardization and interoperability, facilitating the integration between systems. Furthermore, governance allows for effective control of access and use of APIs, protecting sensitive data and mitigating risks
I recommend that the company have an established and centralized API catalog, visible and easily accessible to the designated responsible parties. This can work, inclusive, for reuse, avoiding rework in the development of new APIs that may have already been created, explain Torqueto
"Furthermore, it is essential to use the correct form of authentication and authorization, specific to what the API aims to solve. In the case of applications, for example, with APIs exposed to the general public, and that often undergo various attempts of breach, it is necessary not only to follow a very robust authentication and authorization model, how to conduct penetration testing frequently, identifying possible attack vectors and ensuring that the model is functioning, adds the executive
3) Use AI as another layer of protection
The use of artificial intelligence (AI) in API security has become an increasingly effective strategy for detecting and mitigating threats in real time.
Machine learning algorithms can analyze traffic patterns and identify anomalous behaviors, allowing early detection of attacks, such as code injection attempts or unauthorized access.
It is necessary to think of API security layers like the layers of an onion, one after another, making the striker's life difficult. This includes the implementation of protective measures such as authentication, authorization, encryption, traffic monitoring, use of HTTPS, and even Artificial Intelligence, that can be a great ally in this regard, says Torqueto
AI can automate authentication and authorization processes, improving efficiency and incident response. With the ability to adapt to new threats and learn from historical data, AI-based solutions make API security more proactive and robust, ensuring the integrity and confidentiality of the information exchanged between systems, complete
4) Invest in automation
Automation in APIs is crucial for increasing efficiency and agility in the development and management of systems.
When automating processes such as testing, continuous integration and deployment, teams can reduce human errors, accelerate development cycles and ensure faster delivery of new features
Still, automation facilitates the monitoring and management of APIs, allowing organizations to identify and resolve problems in real time, improving the reliability and performance of applications, and freeing developers to focus on more strategic and creative tasks, driving innovation and competitiveness in the market
"There is no security scale at the necessary standard without automation". Considering that the average number of APIs managed by organizations is over 400, it is recommended that companies have a platform team that automates whatever is necessary to keep the security of their APIs up to date, says Torqueto
5) Be careful when choosing an API provider
Choosing the right API provider is a critical decision that can directly impact the performance and security of a company's systems
Some factors that should be considered when choosing an API provider are the reputation and reliability of the company, security and compliance practices, support, scalability and performance. These precautions will help ensure the choice of an API provider that meets your needs and contributes to the success of your company, concludes
