Cloud Security Risks
Threats in the Cloud
When you move data and apps to the cloud, there are many risks. Attackers search for weak spots in cloud systems every day. If you do not protect your cloud assets, you might lose control of your data. Here are some common threats you should know about:
Insecure APIs can let attackers steal your data if you do not use strong authentication or encryption.
Misconfigurations happen when you set the wrong permissions or leave storage open. These mistakes cause most cloud security problems.
Data breaches can expose large amounts of sensitive information to the public.
Data loss can happen if you delete files by accident or if a hacker wipes your data.
Denial-of-Service (DoS) attacks can flood your cloud services and make them stop working.
Insider threats come from people inside your company who misuse their access.
Account hijacking happens when attackers steal passwords and take over accounts.
Lack of visibility makes it hard to spot attacks or mistakes in your cloud setup.
Poor identity and access management can give users too much power, making it easier for attackers to move around.
Tip: You can lower these risks by using strong access controls, encrypting your data, and watching your cloud environment.
Access and Data Breaches
It is important to know why data breaches happen so often in the cloud. Attackers often use stolen or weak passwords to get in. In 2025, stolen credentials caused 67% of big cloud data breaches. Weak or missing passwords led to almost half of all cloud attacks. When attackers get in this way, they can stay hidden for months. It takes about 292 days to find and stop these breaches.
If you do not manage your secrets well, you make it easier for attackers. Many companies leave secrets in code or files, forget to change passwords, or give too many people access. These mistakes let attackers steal data, cause downtime, or even break the law. You need a strong, centralized solution to keep your secrets safe and lower the risk of a breach.
Azure Key Vault Features
Azure Key Vault has strong tools to keep your secrets, keys, and certificates safe in the cloud. These features help protect your data and follow security rules. Each feature is important for your cloud security.
Key Management
Cryptographic keys are very important because they unlock your private data. Azure Key Vault uses hardware security modules (HSMs) to keep keys safe. HSMs make sure keys stay inside the secure device. This stops attackers from getting your keys, even if they get into your system.
You can pick software-protected keys or HSM-protected keys. If you want the best security, use Managed HSM. This gives you your own hardware, not shared with others. You do not have to take care of the hardware. Azure Key Vault does it for you.
Note: HSM-backed keys help you follow strict rules in fields like finance and healthcare.
