Salesforce Security

Salesforce limits exposure of data to the users that act on it. It implements security controls that you think are appropriate for the sensitivity of your data. Your data is protected from unauthorized access that may happen from outside your company. Also safeguards it from inappropriate usage by your users.

Difference between security and protection :

  • Security means an environment which is open to all
  • Protection means a restricted environment

Why security?

  • SFDC works in multi – tenant architecture

Why protection?

  • All responsibilities are provided by the system administrator
  • The administrator has to provide the required level of security
    → The various levels of security are
  1. Application level
  2. Object / tab
  3. Field level
  4. Record level
    All these above levels of securities are provided through “profile”
    Which is narrow that security will be working


Means which is giving tight security

Process flow

→ There are multiple means of providing the security for eg., a field level security can be achieved through profiles and page layouts.
→ Whichever provides tighter security, those settings will override the other.
→ For every organization a basic level of security is predetermined and is specified through “organization wide defaults” (owd)
→ Owd security settings

  • There are various ways to override these settings, the most popular mechanism is “sharing rules”
  • By using sharing rules we can specify which records can be accessed by which user and in which mode.
  • A collection of users is known as “group”.
  • A single group may custom multiple users as well as other groups.
  • The sharing rule provides secure access to the group.

→ Here are four permissions for sharing rules
1. Private: Only the owner of the record can access it.
2. Public read: Other members in the group can only read the data
3. Public read/ write: Other members can read and edit the data
4. Public read/ write & transfer: All users can view, edit, transfer, and report on all records. Only available for cases or leads. Means we can transfer permissions. Transfer means changing the ownership, through which further permissions can be generated for that user
→ We can override OWD with sharing rules
→ Own user can exist in one profile
→ One role can be accessed to only one user
→ IP address range   ↓
We will restrict
→ Fiscal year  → years financial year
Starting month & ending month, will form a year

Various definitions of customization :

  • Any feature or functions which are not available as a part of  the application and the application need to extend refers to customization.  
  • Despite of configuring the things, there are few actions which are not achievable, thus it results in adding some custom code, which results in Customization.
  • Adding triggers on the object to perform some action is called also termed as customization.
  •  Adding Apex Code, which will generate a vCard from a given Contact is called Customization.

It is used for :

  • To map end user requirements
  • SFDC provides the CRM, details that it has to customize
  • Multi talent architecture is for system architecture
  • Model view collector (mvc) is a development architecture

→ Sales force development architecture is designed by MVC
MVC → design pattern   ↓



A view is a set of search conditions that display items that match the search conditions. By default, includes a number of views for each category of items.
Every time we will get a different page view when we click on the pages.
For every click, the page will give us different page views.

A Visualforce controller is a set of instructions that specify what happens when a user interacts with the components specified in associated Visualforce markup, such as when a user clicks a button or link.
