4. Introduction – Why Security?
Security is one of the most important part of any Website or a Web
Application.
There are various ways to exploit a website/ web application: -
● Brute Force
● Sniffers
● Spoofing
● Social Engineering
● SQL Injection

5. How?
● Design application in good way
● Encrypt sensitive data while storing
● Validate input data before processing
● Force users to give strong password
● Implement Authentication and Authorization technique

6. Authentication and Authorization
Authentication is a process where a user's credential is checked.
e.g. - gmail, facebook etc.
Authorization is a process where a user access the resource based
on his/her role.
Authentication always precedes Authorization.

7. What is a Provider in Asp.Net?
ProviderBase class is an "Abstract Class" which follows the
"Provider Model".
This class is very simple and contains very few methods which is
inherited from the "Object" Class.This class is a part of the
System.Configuration.Provider namespace.
This ProviderBase class implements a 2 step process.
● Feature-specific Providers (Membership/ Role/ Profile
Providers)
● Implementation-specific Providers (SqlMembership Provider)

8. MembershipProvider in ASP.NET
● ASP.NET membership gives us a built-in way to validate and store
user credentials. ASP.NET membership therefore helps us manage
user authentication in web sites.
● ASP.NET Membership provides two types of Membership
providers:-
- SQLMembershipProvider
- ActiveDirectoryMembershipProvider
● ASP.NET provides us to configure our own Custom Membership
Provider. (Oracle Data Source, Other data source)
● This class inherits from the abstract ProviderBase class and
contains various methods and properties to Create, Delete, Update,
Validate, Get User information, Change Password

9. Problems with ASP.NET
Membership
● Requires full SQL server for default cases
● Custom Membership Providers have to work with a SQL-Server-
Centric API
● Designed around a specific view of users, roles, profiles
● Requires specific schema, overflow in blob columns

10. SimpleMembership
● Works with our schema
● Broaden database support to the whole SQL server family
● Easy to use with Entity Framework Code First

11. SimpleMembership integrates
with ASP.NET Membership
