Adaptive Access Control

Few weeks back I went to attend Oracle Openworld in San Francisco and while I was on the demo grounds to see what oracle has to offer in the Identity and Access Control I met one product group which is building a "Adaptive Access Control" product.

This product builds the intelligence based on your previous access controls and compare them on next logon. This can be configured to make the metrics over a predefined period of time and freeze the statistics for next access requests.

For example if you are accessing the system between 8AM and 5PM on a daily basis and one day it gets the request at 10PM then it will deny the access.

This seems a good idea to me except for the reason that how long it takes to capture the metrics and how it handles the exceptions.

Another scenario could be that you access the system from North America reason and one day it sees the request from India then it has a valid reason to suspect the request.

Open Source identity and Access management : VELO

Fortunately I got a chance to directly talk to Asaf Shakarchi (father of VELO) and I asked him why you named it VELO.

Asaf: It was taken by "velo binding". You can read about it in wiki.

My understanding: I then read about it in the Wiki and tried to link it with the identity and access control and realized the name is so true as the product is also trying to link and bind and control the identities.

I also asked him what is the function of remote performer and below is what I understood from his explanation

Remote performer is a kind of load balancer which can be used to delicate the responsibility of the VELO server. For example if the environment has many resources and you don't want to wait for the responses from the resource once you provision, you can use VELO remote performer. All the requests will be delegated to the remote performer and VELO server can perform other important tasks.

Remote performer is not a must for deploying VELO but it can give additional flexibility to distribute the load.

Hub and Switch and Router
