What is Cloud Security?

Cloud security is a set of technologies designed to protect data, apps, and cloud computing infrastructure. Policies and controls also form a part of cloud security. 

You need cloud security to stop unauthorized access and data breaches from leaking sensitive information. Preventing potential business disruptions and safeguarding trust are critical aspects of security.

The shared responsibility determines that cloud service providers (CSPs) and customers are responsible for security. CSPs look after the security “of” the cloud (e.g., underlying infrastructure, physical data centers, networking, and software/hardware). 

Customers, meanwhile, are responsible for the security “in” their SaaS cloud. Responsibilities include: 

• Data: Customers control who has access to applications, how apps/data are used, and where these are stored. 
• Access Controls: Manage permissions, user accounts, and authentication methods to limit access to only authorized individuals. 

The main areas to consider when using SaaS are:

1. Data Breaches: Protect yourself against financial/reputational damage by addressing data loss, sensitive information exposure, and unauthorized access early.  
2. 配置管理对于确保安全控制和设置得到正确配置至关重要，从而减少漏洞和潜在攻击。

客户拥有存储在SaaS应用程序中的数据，组织应采取以下措施来保持控制： 

• 了解SaaS提供商的数据处理实践：查看您的提供商的服务条款和数据处理协议。了解他们如何保护、存储和处理数据。 
• 实施强大的访问控制：多因素身份验证 (MFA)、访问审查审计和基于角色的访问控制 (RBAC) 至关重要。 
• 数据加密：加密传输中和静态数据。这样做应该可以阻止未经授权的访问。 
• 数据备份：执行独立的SaaS数据备份，以便在出现问题时可以恢复信息。

使用以下方法来确保SaaS云安全： 

• Strong Passwords/MFA: Use strong passwords (and make employees regularly change these). Use MFA, such as two-factor authentication, for an additional layer. 

• 定期更新和补丁：保持SaaS更新，并尽快下载安全补丁。 
• Employee Education: Train employees so they know about cloud security practices. They should understand how to set strong passwords, handle data safely, and identify phishing emails. 
• Regular Audits & Assessments: Perform audits to find and address possible risks; vulnerability assessments are also essential in this regard. 
• Incident Response Plan: Know what you’ll do to take action quickly if something goes wrong.
