Securing API's

-

Securing APIs , every one talking about development of API using spring boot, python,.net,java...etc. but no  one talks about how to secure the APIS.

Here I'm talking about security in 5 ways

BASIC

This works by providing your credentials i.e userId and password works by setting "Authorization" request header with the value as Base64Encode(username:password)

curl -X GET \

http://localhost:8080/hellow \

-H 'Authorization: Basic a12dksl32weld2sdld3d2dsd='\

-H'Postman-Token:

30befeb9-83e4-46e8-8633-cf4ad2400936'\

-H 'cache-control:no-cache'

API KEY

Random string (e.g. UUID) is assigned to each API consumer

This key is passed either as query PARAM or as a request header

usually "X-API-KEY" is used as query PARAM or request header


curl -X GET \

http://localhost:8080/hellow \

-H 'Postman-Token:

30befeb9-83e4-46e8-8633-cf4ad2400936'\

-H 'X-API-KEY: 21312332133adada-1231asd-123a-123131312313' \

-H 'cache-control:no-cache'

Bearer Token

This involves giving access to the "bearer of the token" Normally we pass this in the "Authorization" request header with value as "Bearer<token>".

Bearer token scheme was originally created as part of OAuthr2.0

curl -X GET \

http://localhost:8080/hellow \

-H 'Authorization: Bearer 21231231daddadadadadadaadads'\

-H 'Postman-Token:

30befeb9-83e4-46e8-8633-cf4ad2400936'\

-H 'cache-control:no-cache'


TLS/Mutual TLS

TLS is a standard that keeps an internet connection private and checks that the data sent between client and a server, or a server and a client i.e whether it is encrypted and unmodified

Mutual TLS, also called as bi-directional TLS where both Client and Server validates the authenticity of each other.

Client Verifying the Server

The Server sends its digital x.509 certificate(and any intermediate certificates) to the client. The client verifies the server's certificate by using one of its pre-trusted root certificates. Most clients use the Microsoft or Mozilla set of trusted root certificates. At the end of ths process, the client knows the exactly who the server is.

Server verifying the client

The TLS handshake Certificate Request message is optionally sent by the server to the client. The certificate request message includes a list of distinguished names of root certificates that the server trusts.

It tell the client(DocuSign in our case) to respond with it own certificate and any needed intermediate certificates.

Email Sending through O365 using OAuth Protocol

-
  Microsoft Office365 EWS servers have been extended to support authorization via the industry-standard OAuth 2.0 protocol. Using OAUTH protocol, user can do authentication by Microsoft Web OAuth instead of inputting user and password directly in application Microsoft / Office 365 OAuth + EWS We can use the OAuth authentication service provided by Azure Active Directory to enable our application to connect with IMAP, POP or SMTP protocols to access Exchange Online in Office 365. To use OAuth with our application we need to register application on Azure Active directory and other steps also we need to do to get the access token back. Below are the steps   To use Microsoft/Office365 OAUTH in your application, you must create an application in  https://portal.azure.com . Sign into the Azure portal using either a work or school account or a personal Microsoft account. If your account gives you access to more than one tenant, select your account in the top right corn

IISRESET vs App Pool Recycling ?

-

 I think most IIS administrators know IISRESET command, and why they use it. One of possible reasons can be to restart IIS services to initialize web applications, or to apply some changes of applications & IIS settings .There’re just a few conditions those need your IISRESET command. In most situations, you don’t need this. I have a concern if you always run this command for applying any changes, or release system resource – memory – regularly, or frequently. Because it’s much more cost than what you really need to take – there’re side effects Recycling App Pool’ has been introduced from IIS6 in Windows2003. It’s designed to restart only application pools(=worker processes). It can be done in a command prompt(run ‘IISAPP /?’ in a command prompt for details), as well as in the IIS manager What IISRESET does? When you run IISRESET, many things will happen. In order to understand them, I think I need to show you how IIS looks like – about IIS core components. The below shows you role

Deploy .Net6.0 Web api with docker

  What is Docker? Docker is a containerization platform, meaning that it enables you to package your applications into images and run them as “containers” on any platform that can run Docker. It negates the classic: “It works on my computer” argument as Docker images contain everything needed for the app to run. Are Containers the same as Virtual Machines? They are similar, but not the same. In short: Virtual Machines provide OS Level Virtualization Containers provide App Level Virtualization This concept is depicted below: Why Would You Use it? In short you would use Docker, (and hence containers), for the following reasons: Portability.  As containers are self- contained  they can run on any platform that runs Docker, making them easy to stand up and run on a wide variety of platforms. Scalability.  With the use of additional “orchestration” you can spin up multiple container instances to support increased load. Performance.  Containers generally perform better than their VM counterp
