Security

Checklist Item
Category
Make class final if not being used for inheritance
Fundamentals
Avoid duplication of code
Fundamentals
Restrict privileges: Application to run with the least privilege mode required for functioning
Fundamentals
Minimize the accessibility of classes and members
Fundamentals
Document security related information
Fundamentals
Input into a system should be checked for valid data size and range
Denial of Service
Avoid excessive logs for unusual behavior
Denial of Service
Release resources (Streams, Connections, etc) in all cases
Denial of Service
Purge sensitive information from exceptions (exposing file path, internals of the system, configuration)
Confidential Information
Do not log highly sensitive information
Confidential Information
Consider purging highly sensitive from memory after use 
Confidential Information
Avoid dynamic SQL, use prepared statement
Injection Inclusion
Limit the accessibility of packages,classes, interfaces, methods, and fields
Accessibility Extensibility
Limit the extensibility of classes and methods (by making it final)
Accessibility Extensibility
Validate inputs (for valid data, size, range, boundary conditions, etc)
Input Validation
Validate output from untrusted objects as input
Input Validation
Define wrappers around native methods (not declare a native method public)
Input Validation
Treat output from untrusted object as input
Mutability
Make public static fields final (to avoid caller changing the value)
Mutability
Avoid exposing constructors of sensitive classes
Object Construction
Avoid serialization for security-sensitive classes
Serialization Deserialization
Guard sensitive data during serialization
Serialization Deserialization
Be careful caching results of potentially privileged operations
Serialization Deserialization
Only use JNI when necessary
Access Control

General Programming
Refer to objects by their interfaces
General Programming
Adhere to generally accepted naming conventions
General Programming
Avoid finalizers
Creating and Destroying Objects
Always override hashCode when you override equals
General Programming

General Programming
Use enums instead of int constants
Enums and Annotations
Use marker interfaces to define types
Enums and Annotations
Synchronize access to shared mutable data
Concurrency
Prefer executors to tasks and threads
Concurrency
Document thread safety
Concurrency
Valid JUnit / JBehave test cases exist
Testing
