Within this chapter, we'll traverse these missteps and put forth appropriate fixes to assist in their evasion.

Misstep 1: Overlooking the Application of OAuth2

OAuth2, an essential protocol, furnishes constrained access to user accounts on an HTTP service to applications. Despite its significance in API fortification, several developers erroneously bypass its proper incorporation or disregard it entirely.


public class OAuth2 {
    public static void main(String[] args) {
        // Incorrect usage of OAuth2
        OAuth2Service oAuth2Service = new OAuth2Service();
        oAuth2Service.authorize("username", "password");
    }
}

The afresh code piece reveals the inappropriate usage of OAuth2. Hardcoding the username and password pose a significant risk to security. Alternatively, utilize a locked-down approach to preserve and fetch these essential credentials.

Misstep 2: SSL/TLS Configuration Mismanagement

The protocol, SSL/TLS, is employed to establish a secure link between a server and its client. Still, any mismanagement in its configuration might result in potential safety weak points.
