Special tips and solutions to secure API endpoints
June 18, 2021
What is an API?
The unique term API may refer to either specification or the implementation, and it is an application programming interface that creates a connection between the computers and the computers programs. So, the document or the standards which describe such connections are known as the API specification, and the computer system which meets all these standards is known to implement or expose an API. You may also visit API uses in everyday life.
API and its connection
An API shares a boundary between the system where the communication takes place as it is a type of interface. On a contrary, a user interface can connect a desktop to a person, and an application programming interface connects all the computers of the software. Now, these are not intended, for use directly by an individual, other than the programming on the computer, who is putting it into the software. An API is created with different types of services that are available to all the programmers. So, a programmer who is said to use all these features are known to be a portion of an API, and the calls which make the API are known as the subroutines, the methods, requests, and the endpoints. Hence, the specifications on the APIs may define all these features and implements those.
The basic purpose of API
It has one basic purpose which involves, is the function to hide all the internal details on the process of working of a system, it exposes only a specific part of the programmer that is useful and keeps them consistent even when the internal details change. An API has the feature of customization for only a particular pair of the systems, and sometimes it is also shared by the standard allowing interoperability among all the systems.
The web API
It creates communication between all the computers which are joined by the internet. It has the very common phenomenon of API for today. There are also APIs for many programming languages, software libraries, and computer operating systems, and also computer hardware.
The importance to secure API endpoints
These API endpoints are the basic URL that is exposed by the server, and it also allows the other services to get connected and get consumed with its services. These act as entry points into the corporate networks and are often provided valuable or sensible information and these also make them an attractive target.
The different types of API attacks
The distributed denial of the services
It is quite common for providing a face request to API, which a legitimate denial to the access, this is called the denial of service (DoS) attack. And as it is performed by the compromised machines it is known as the Distributed Denial of Services.
The data exfiltration attacks
It usually mentions extracting a huge amount of information from the API than the user who is authorized to receive it. This usually involves manipulating the search filters to returning out the range records. API is designed with automated access so it is usually easy to carry out these attacks.
The functionality and the different resource attacks
It usually involves some basic functionalities, which are very important for cybercrimes. The attacker sometimes uses the functions given by the API in a very exceptional manner.
The few common areas
The mails– The mails are often used as a means of sending notifications as well as the basic communication by the spammers.
Publish of the content– Few APIs provide the user to edit or publish the content on the web. But this is very dangerous as well as contains high-risk factors.
The upload of the files -To upload the content is sometimes disrupted by many, who want to spread unethical content as well as improve search rankings. But for many years the SEO tried to upload the file on the HTML which contains the link. But, the more severe cases it infects the server and also the devices of the individual who uploads the content.
The best procedures of securing the API
The practices to improve the API endpoint are as follows:
The User authentication with the API
The API key is the most fundamental API security of all time and is often used to have complete access to the REST services. The API keys can also be used by the public operators to rate-limit the calls and deny the service attacks.
When the API endpoint allows the API users to have a better conversation with the HTTP and with the other, unsecured protocols, the private keys, and the credits. These can be easily cheated on as this can be read on plain text by the packet sniffers. So, for security, the API communicates with an option available.
The One-Way Password
The one tips which is always helpful is not saving the password in the cleartext and also to avoid the symmetric encryption methods as it is sufficiently sophisticated.
Applying the rate limits
The best way to have a secured API is to limit the calls that the user makes. This can ultimately prevent the DoS attacks in which hundreds of concurrent requests per second are sent by the bots.
The IP address filter
The API considers adding the layer of security which limits the IP address. In this, it is needed to verify the IP address in every location.
The validated input
A huge number of the API fails to sanitize the inputs which ultimately allows the attackers to perform a range of different code injection attacks. In the process of verification, it should be noted that the data is received in a proper format and the strip characters that be a part of the malicious code.
The API client filtering
Client filtering is a necessary part to minimize the security risk. And it considers the minimum permission and the capabilities to consume the API.
