6. Account Hijacking
Another major security risk in cloud applications is account hijacking. In this, hackers breach an individual user’s or organization’s cloud account (for example, a bank account, email, or social media account). They use these accounts for unauthorized access and perform fraudulent activities.
7. Insider Threats
Another main threat to cloud applications is insiders. These can be current or former employees of the organization, workers who are negligent in their actions, or attackers who have gained the trust of innocent employees. The risk of insider threats has increased recently, mostly due to the rise of remote workers, policies like Bring Your Own Device (BYOD), or former employees whose jobs were affected by the pandemic.
Best Practices of Cloud Application Security Testing
Organizations need robust security measures during the development and deployment of cloud applications. Here are the best practices to ensure effective cloud application security testing:
