Designing Applications

Designing Applications
Designing Applications for Multiple Users
Design Considerations
need to know the users or actors of the app
need to identify
data that can be accessed by users
data restrictions and revoke access from such sensitive data
users who should be allowed to customize the app and assign the necessary permissions
Managing your user’s experience
Types of licenses
every user must have a user license
defines the fucntionality permitted for the user and determines the profile available to the user
can have only type of user license, but may have many feature licenses
Two types of license
full access to CRM, appexchange apps, standard or custom apps
full access to CRM, appexchange apps, standard or custom apps
Salesforce Platform
custom apps, appexchange apps, no access to CRM functionality, can still use accounts, leads, contacts, reports, dashboards and documents
can have add-on features, such as apex mobile user, sf crm content user, marketing user
can have more than one type of feature license
define user permissions to perform different functions
each profile is associated with a license type
profile work with sharing models or role hierarchy
profiles control permissions, access to data and the UI
define all actions that a user in a profile can perform
access to data
controlled by field level security settings which allow to define object and field level permissions
user interface
page layouts, tabs, applications available for each user, record types for each profile determine what the users will see when they login
two types of profiles
can’t be created or deleted and permissions cannot be customized
create or clone the standard profile and modify the settings
types of permissions
can grant some administrative permissions to custom profile
General User
control the ability that standard user can do like editing tasks
Standard Object
control read, create, edit and delete action on standard objects
Custom Object
control read, create, edit and delete actions on custom objects
View All Data allows administrators to view all records regardless of all other security settings
Modify all Data – allows administratos to modify all records
Customize Application permits administrators to administer the application
API only user cannot login to such users can only use the application through API calls
Password Never Expires prevents password expiring
Permission Sets
collection of settings and permissions
represent a concept like job title
handle the system requirements that previously existed on the profiles
user can have only one profile, but can have multiple permission sets
while assigning permissiosn to users, use profile to assign most restrictive settings and assign additional permissions using permission sets
an org can have upto 1000 permission sets
permission sets can be used assign additional permissions, but not to deny permissions
permissions can be revoked by
removing permission from permission set
changing a user’s profile
disabling a permission set
use permission sets to grant permissions for
applications, objects, fields, tabs, apex classes, service provider, visual force pages
permissions that are not available in permission sets must be set through profiles (login hours, ip access, etc)
revoking delete permission for a child object in master child relationship will not prevent deleting the child record if parent record is deleted
Field-Level Security
restricts access to fields
list views, reports,, conenct offline, custom links, mail merge, related lists
overrides less restrictive page layout settings
set at profile level
each profile can have different level of access to object
doesn’t allow conditional security of records
all users can edit any accessible fields
Customizing UI and Profiles
Record types
define the manner in which data is displayed according to business needs
determine the page layout and limit the picklist options based on the profile
not security tools – do not subclass or partition the data, they work at the UI level and not at the data level
users can change the record type of an existing record and it does not affect the values in the record
Controlling access to records
Record ownership
has a owner, sharing based on owner of a record, can be transferred to any user who atleast has read access
child records in master detail relationship do not have owner, they inherit from parent record
Types of owners
users – full access if a user is owner. if read permission revoked, then they can’t see their own record
queues – allows multiple ownership, assigned manually or thru assignment rules
Record Access
read only access, read-write access, full access
Ways to obtain record access
Full access: owner, above the owner in role hierarchy, contains modify all data permission in profile
Read/Write or Read only: owd, role hierarchy, sharing rules, manual sharing, apex sharing, view all data
Profiles vs Sharing Models
control access to objects and fields
whether user can view positions
which fields the user can view
Sharing models
control access to records
control the positions to view
security settings that define the base line level of access to records that the user doesn’t own
only way to restricts access to data in sharing model
3 level of settings
public read-write
public read only
Determining OWD
identify the most restricted user of this object
will there be an instance of object that this user is not allowed to view
if yes, then owd is private
will there be an instance of object that this user is not allowed to edit
if yes, then owd is public read only
else, then owd is public read-write
setting owd for child records in master-detail relationship – child inherits owd from parents
child records in lookup will not inherit owd
it is possible to change owd any time, but it may have consequences
owd can be set for both standard & custom objects
control the level of visibility to org data
every user associated to role
assuming no sharing rules created, users in the same role cannot access each other’s records
Role Hierarchy
defines data access rights granted to users at higher roles
users access to all records they own and their sub-ordinates
record access rolls up with role hierarchy with all standard objects
with custom objects, a setting named ‘Grant Access using Role Hierarchy’, this can be prevented
Public Groups
Roles are two dimensional structures. Public groups are way of grouping users together to grant them record access.
Groups are good way to extend access across the nodes in hierarchy tree
‘All Internal users’ is a default public group. Public groups can be made up of any combination of users, roles and subordinates and other public groups.
Can use public groups in a sharing rule to reduce the number of sharing rules
Public groups can also be used for folder access.
Sharing rules
are created to grant access to records between users when access does not roll up
Using sharing rules, read only and read/write access can be granted to users
Sharing rules cannot be more restrictive than owd settings.
Manual Sharing
used to grant access to records on a one-off basis when randon users require record access.
Access rights can be granted by the owner of a record, anyone above the owner in the role hierarchy and by the system adminsitrator
It is granted at the record level and is not used to grant access at the organization level
Apex sharing reasons
allow developers to define the reason why a user or group of users have access to record
apex sharing reasons exist only for custom objects and they are defined for individual objects.
each object can have up to 10 apex sharing reasons
sharing rule has to be created manually using new manual sharing rules
deleting apex sharing reasons will delete all manual sharing rules associated with it
Users with ‘Modify all data’ permission can change sharing using apex sharing reasons
apex sharing reasons should be used programatically and not through the application
Designing Data Access Security
Establishing Data Access
When you want to determine data access for a object,
consider the OWD default
the owner of the records
uses who need access
rules governing data access
When determining access to sensitive data, you need to analyze the access requirements and restrictions for each profile
