+* Proposal: 0001-brute-force-attack-detection
+* Authors: [Simon Berry](https://github.com/simonaberry)
+* Review Manager: TBD
+* Status: **Awaiting review**
+
+## Introduction
+## Motivation
+
+Cyberthreats are a real problem. Any servers running Parse Server are susceptible to hack attacks. The simplist would be a brute force attack - as there are no in built limits to login attempts. This is particulaly relevant as the default ACL on any new user added is Public Read - so it is fairly straight forward to get the usernames for all the users on a vanilla Parse Server (unless the developer has been good about changing teh User class ACLs). 
+
+## Proposed solution
+
+* Introduce a paramater that allows the developer to specify the maximum number of incorrect attempts (configurable) on a specific username before 'freezing' the account for a given time frame  (configurable)
+
+OR
+
+* Introduce an 'AfterLogin' hook in cloud code that resolves a promise if login was successful or rejects a promise if login was unsuccessful. This would allow the user to write his own logic to implement an account freeze if a certain number of incorrect logins were attempted
+
+## Detailed design
+
+Don't know the Parse Server code well enough to suggest detailed implementation
+
+## Alternatives considered
+
+could also possibly monitor the log files using a library like this https://github.com/rfxn/brute-force-detection
