How to secure API with Kong ?

The Unsung Hero in API Security - A Comprehensive GuideIn this new era of interconnectedness, Application Programming Interfaces (APIs) stand as vital conduits that link various software, fostering information exchange and interactivity. Yet, as the importance and usage of APIs magnify, so does the intensity of security battles. This discourse seeks to cultivate an in-depth comprehension of API security and the obstacles it poses.

Consider APIs as the translators and messengers that orchestrate interactions between distinct software platforms. They establish the conventions and formats for information interchange, paving the way for their integration into an array of applications - from web-operated services such as social networks and digital data archives, to smartphone applications and Internet of Things (IoT) gadgets.

However, APIs also pique the interest of cybercrooks. When APIs lack sufficient defenses, they expose potential gaps for unauthorized intrusion, data leaks, and sometimes, interruptions of service. Hence, the need for solid API security - an assembly of methodologies and technologies designed to thwart malignant breaches on inter-application interaction points.

The critical focus points for API security battles often consist of:

1. Identity Verification: This involves ascertaining the identities of parties partaking in the API operation, typically facilitated via API keys, OAuth tokens, or JWT (JSON Web Tokens).

# An illustration of API key identity verification
import requests

access_key = 'your_key'
header_data = {'Authorization': 'Bearer %s' % access_key}

server_response = requests.get
('https://api.example.com/info', headers=header_data)

2. Access Control: It regulates the functionality reach of the verified party, usually administered through an approach based on roles (RBAC) or characteristics (ABAC).

3. Data Protection: This element ensures that the data moving via the API remains safeguarded through encryption methods such as SSL/TLS.

4. Request Regulation: To prevent API misuse, it limits the quantity of requests a user can initiate within a specified duration.

5. Data Scrutiny: It involves the examination of data submitted via the API to ward off attacks such as SQL injection or cross-site scripting (XSS).

6. Tracking and Surveillance: It involves detailed monitoring of API utilization to spot aberrant or dubious activities.

Regardless of these defenses, API security is a rugged territory due to aspects like the escalating intricacy of APIs, the swift momentum of technological progression, and the ever-adapting landscape of cyber hazards.

In the ensuing discourse, we will shed light on Kong - a widely-accepted open-source API gateway that delivers sturdy defenses for API security. We will delve into the methods to fortify API using Kong, outlining a comprehensive procedure to construct impregnable fortresses against API security confrontations.

Commanding Kong: A Brief Guided Tour on API Protection with Kong

Within the dominion of API fortification, Kong emerges as an unignorable power. It exists as an open-source API doorway and foundation functioning as an intermediary between digital clientele and API-based applications. Kong brings to the table an impressive level of adaptability with the possibility of personalization through numerous plugins, solidifying its position as a multifaceted instrument for guarding APIs.

The principal role of Kong is to fortify APIs while overseeing, coordinating, and observing API traffic. To validate the security, efficiency, and dependability of APIs, Kong equips itself with a formidable array of features, encompassing authentication, traffic control, record keeping, among others.

API security finds its first bulwark in authentication. Kong accommodates a myriad of authentication modes, comprising key validation, JWT, OAuth 2.0, etc. Here's a practical demonstration of how to facilitate key verification for an API via Kong:

# Incorporate the API into Kong 
$ curl -i -X POST \
  --url https://localhost:8001/apis/ \
  --data 'name=my-api' \
  --data 'upstream_url=https://my-api.com' \
  --data 'hosts=my-api.com'

# Employ the key-auth plugin for the API 
$ curl -i -X POST \
  --url https://localhost:8001/apis/my-api/plugins/ \
  --data 'name=key-auth'

Traffic control stands as another pivotal facility of Kong. It curbs API exploitation by regulating the volume of requests a client can dispatch in a specific timeframe. Here's an exemplification of instituting traffic control via Kong:

# Employ the rate-limiting plugin for the API 
$ curl -i -X POST \
  --url https://localhost:8001/apis/my-api/plugins/ \
  --data 'name=rate-limiting' \
  --data 'config.minute=100'

The above code restricts the limit to 100 requests per minute. Clients surpassing this limit will encounter a 429 "Too Many Requests" rejoinder.

Moreover, Kong extends comprehensive logging services. It can document API requests and feedbacks to a multitude of locations, including stdout, stderr, file, HTTP, TCP, UDP, etc. This feature comes in handy while scrutinizing API consumption and diagnosing hiccups.

Following is an instance of initiating file logging for an API with Kong:

# Employ the file-log plugin for the API 
$ curl -i -X POST \
  --url https://localhost:8001/apis/my-api/plugins/ \
  --data 'name=file-log' \
  --data 'config.path=/tmp/kong.log'

In this case, the API logs will be recorded in the file /tmp/kong.log.

The agility and expandability of Kong elevate its value as an efficacious armament in API security. Yet, it mandates appropriate utilization to yield desired results. Examination of a step-by-step process to safeguard an API with Kong will unfold in the upcoming chapter.

Remaining in sync with these releases assures that your API is guarded against familiar vulnerabilities, thereby integrating contemporaneous security aspects.

Restrict Rates of Requests

Restricting request rates is an imperative aspect of securing APIs. It bars an individual user or IP from overloading your API with an immoderate volume of requests, thereby potentially paving the path for a Service Denial (DoS) assault. Kong proposes a user-friendly, configurable plugin for request rate restrictions.

# Install rate restriction plugin
$ curl -i -X POST https://localhost:8001/services/{service}
/plugins \
    --data "name=rate-limiting" \
    --data "config.second=5"

Opt for HTTPS

HTTPS should always be preferred over HTTP to guarantee that all client-server data exchanges are encrypted. Kong backs HTTPS and can be adaptively configured to divert HTTP requests to HTTPS.

# Set Kong to employ HTTPS
$ curl -i -X PATCH https://localhost:8001/services/{service} \
    --data "protocol=https" \
    --data "port=443"

Authenticate and Authorize User Access

It's important to verify and authorize users before granting access to your API. Kong puts forward a variety of plugins for the authorization and authentication of users, inclusive of Key Authentication, JWT, and OAuth 2.0. Opt for the one that fits your criteria best.

# Install key-authentication plugin
$ curl -i -X POST https://localhost:8001/services/{service}
/plugins \
    --data "name=key-auth"

Keep an Eye On and Record API Operations

Conducting regular surveillance and maintaining logs of API operations is integral for the timely detection and resolution of security anomalies. Kong lends plugins that log data at multiple destinations such as HTTP, Files, TCP, UDP, and many more.

# Integrate file log plugin
$ curl -i -X POST https://localhost:8001/services/{service}
/plugins \
    --data "name=file-log" \
    --data "config.path=/var/log/kong/kong.log"

Adopt Security Headers

Security headers offer additional security as they help dodge rampant web susceptibilities. Kong offers a plugin to include security headers to your API responses.

# Incorporate security headers plugin
$ curl -i -X POST https://localhost:8001/services/{service}
/plugins \
    --data "name=response-transformer" \
    --data "config.add.headers=X-Frame-Options: 
    DENY, X-Content-Type-Options: nosniff"

Induct IP Whitelisting

IP whitelisting helps you dictate who has accessibility to your API depending on their IP locations. Kong possesses a plugin dedicated to IP whitelisting.

# Incorporate IP whitelisting plugin
$ curl -i -X POST https://localhost:8001/services/{service}
/plugins \
    --data "name=ip-restriction" \
    --data "config.whitelist=192.168.1.1,192.168.1.2"

By sticking to these superior practices, you can largely reinforce the protection of your API utilizing Kong. It's integral to remember that the process of fortifying API security is ceaseless that necessitates perpetual attention and upkeep.
