Policy file grant statements can now optionally include one or more Principal fields. Inclusion of a Principal field indicates that the user or other entity represented by the specified Principal, executing the specified code, has the designated permissions. A Principal field looks like the following: A Principal class is a class that implements the java.
You want to know who is using your app, so you require some form of user authentication and authorization. If your client app is tightly coupled with your API back end, then you probably know and are authenticating the end users of your client.
For example, you could be providing a bike sharing API, and an independent local transportation app is booking one of your bikes on behalf of a local commuter. In addition, to identifying and authorizing users, you are going to want to identify which app is calling your API so you can monitor API usage and possibly enforce API usage policies on a per app basis.
Typically, you will have the app developer register the app with you and you will assign him an API key which acts as a unique app identifier. The API calls have provided valid user access tokens, so you have been letting them through, but users are starting to complain.
A significant number of users are asking for billing audits. They are claiming you are charging them for API calls they did not make. Additionally, some users are complaining that your service is sluggish.
Your back-end costs are increasing, and you are noticing another trend where some users are making expensive search calls which tax your back end, but the percentage of those users who are following through with a monetizing API call, such as a full purchase, is dropping off substantially.
Reluctantly, you conclude that you are under attack. So you decide to start dropping API calls with missing or unrecognized API keys, and you tighten up your rate limiting and behavioral analysis controls, hoping that you are not rejecting too many valid users making valid API calls.
Things improve briefly, but a key without a secret is kind of like requiring a user name without a password. You might require both key and secret to be passed with each call, or you might send the key but use the secret to sign each API call.
Either way, the API key and secret must be kept confidential. Unfortunately, your API security is now dependent, not on you, but on each app developer Are you really comfortable with that?
Instead of embedding a static secret inside each app, you periodically challenge the app to ensure it is authentic. Once verified, you issue it an app authorization token that can be passed with each API call.
Like a user access token, an app authorization token has a limited lifetime and is signed and verified using a secret which is not in the app nor sent through an API call. You previously required an app developer to register his app at the beginning of development.
You can use secure app identity to: By authenticating instead of just identifying your apps, the quality of your traffic has increased. By countering the attacks, your traffic has become more predictable, so your back-end costs are under control, users are no longer complaining about sluggish response times, and you are not losing revenue through unauthorized API usage.Oct 04, · Many grapple with the concept of authentication in information security.
What tends to happen is that they confuse authentication with identification or leslutinsduphoenix.com Of Birth: San Francisco, CA. Identification and Authentication Methods Let’s look into most common Identification and Authentication Methods: User Id: It is the most standard form of identification and is used most often by organizations as a mode of identification to distinguish a user amongst others.
Identification and authentication mechanisms shall be implemented at the application level, as determined by a risk assessment, to provide increased security for the information system and the information processes.
Identification, Authentication, and Authorization Posted by Darril in CISSP, Security+, SSCP | 2 comments If you’re studying for one of the security certifications like CISSP, SSCP, or Security+ it’s important to understand the difference between identification, authentication, and authorization.
Identification, authentication, and authorization. We all face these three concepts every day, but not everyone knows the difference. Since these terms are essential in data protection, they deserve to .
