Dealing with Passwords in Java Applications: 5 Best Practices You Should Follow

In modern Java applications—whether core Java applications or enterprise-level web applications—working with passwords is inevitable. Passwords are sensitive pieces of information, just like Social Security Numbers (SSNs), and if you’re handling real human data in systems such as online banking or healthcare portals, it’s critical to implement best practices for dealing with passwords securely. Below, I’ll share five essential best practices that I’ve learned and recommend for managing passwords, particularly when you are handling authentication and authorization. While these tips are a good starting point, be sure to tailor them to your application’s requirements and security policies. 1) Use SSL/TLS to Transfer Username and Password When users send passwords over the network, it is crucial to use SSL/TLS to encrypt the communication. This ensures that sensitive information is protected from eavesdroppers. Tools like LDAP and Active Directory are commonly used for storing usern...

Fail Fast and Fail Safe Iterator in Java

The concepts of "fail-safe" and "fail-fast" are often discussed in the context of data structures and algorithms, particularly in Java programming. Let's understand what each concept means: Fail-Safe: Fail-safe refers to the property of a system or data structure that guarantees it will not fail, crash, or produce incorrect results, even when it encounters unexpected inputs or concurrent modifications. In the context of Java collections, a fail-safe iterator is an iterator that does not throw a ConcurrentModificationException if the collection is modified while it's being iterated. Instead, it operates on a copy of the original collection or uses some mechanism to handle concurrent modifications safely. For example, the Iterator returned by HashMap or ConcurrentHashMap in Java is fail-safe. If a collection is modified while an iterator is traversing it, the iterator will continue to operate on the original elements that were present when the iteration ...
