Penetration Testing is a method of testing the security of your organization’s infrastructure and architecture. If you are unfamiliar please view what is penetration testing?
By analyzing the attacks in an organization there might be either internal threats or might be External one which may be different methods of Penetration testing
What is External Penetration Testing?
Testing the organization infrastructure which can be externally accessed from the internet
Example: A website, a router etc.
What is Internal Penetration Testing?
Minor internal security flaws may create organization’s internal infrastructure vulnerable thus the testing of an internal device in an organization is an Internal penetration Testing
Example: LAN, internal database server
From the above figure, we can analyze that
Internal penetration testing is related to the internal part of an organization which includes domain controller, database server and organizations infrastructure like routers, systems etc. these are not connected to an external source
Ex- Database relating to the Employees, clients, and projects handling are Internal
External penetration testing is related to the external part of the organization which is connected to external network i.e. Internet. The device which is tested with accessing the internet can be classified into external penetration testing.
Ex- Database relating to the products they are sold online
Now let’s discuss the difference between an Internal Penetration Testing and External Penetration Testing?
|INTERNAL PENETRATION TESTING||EXTERNAL PENETRATION TESTING|
|Source||Internal infrastructure security testing||External infrastructure security testing|
|Devices||Device and services like servers, system, database, network, source code are tested||Device like firewall, cloud, network, external database connection, website and web applications are tested|
|Security breach||Security breach is due to coding errors, system infrastructure mismanagement, database insecurity, personal authentication loss, unprotected authorization||Security breach is due to the configuration error of firewall, coding error on website and authentication or insecure cloud service, unprotected authorization|
|Area of protection||It protects internally protected infrastructure||It protects External environment and also examines the defect of internal|
|Attacking problem ratio||Fewer numbers of attack||MoreNumber of attacks|
|Testing problems||It is confined within limits of accessibility||All the resource need to be tested thus can be more problematic|
|Duration||Testing cause less time as Testing infrastructure is confined or limited||Testing cause more time when comparing to internal as every Infrastructure connected to internet need to be tested|
