Cloud Security Posture Management (CSPM)

Why is CSPM Important?

CSPM is important because cloud environments are highly dynamic, with more users deploying resources and services through self-service access. 毫无疑问，保护云基础设施免受网络罪犯的侵害是一个非常复杂的过程. This complexity continues to increase as enterprises now leverage a mix of public, private, hybrid, and multi-cloud architectures.

Needless to say, old cybersecurity paradigms largely don’t apply to the cloud. 例如，由于云环境不像旧的网络设计那样有明确的边界， identity and access management (IAM) is infinitely more challenging. Additionally, manual SecOps processes become inefficient at scale. Also, 传统网络的去中心化特性使管理员难以监控活动和潜在威胁.

Simply put, complex cloud architectures remain difficult to configure and manage. 事实上，高德纳指出，95%的网络安全漏洞是由配置错误造成的. So, 正确配置任何云环境在保护其免受各种威胁方面起着关键作用 threats, whether in the form of deliberate attacks or unintended mistakes.

CSPM工具提供了必要的云可见性，可以在配置错误造成破坏之前检测和防止配置错误. 自动化功能可确保尽快识别和处理威胁. 在未来，一些CSPM解决方案甚至可以利用人工智能来预测可能出现的风险. Ultimately, CSPM tools offer organizations visibility, protection, and remediation as part of an overarching cloud security strategy.

What are the Benefits of CSPM?

在多云基础设施即服务(IaaS)环境中使用时，CSPM的优势最为有效. 公司在其云环境中受到保护，避免因配置错误而导致安全漏洞. Let's take a look at some key benefits: 

• CSPM platforms provide unified visibility 跨多云环境，因此可以自动检测和修复配置错误. 
• CSPM tools provide a single source of truth for administrators monitoring enterprise cloud infrastructure. Alerts are transmitted using one common system, as opposed to separate ones for each cloud service provider. 
• Automated remediation helps reduce the likelihood of false-positive alerts. This feature helps administrators work more efficiently and effectively. 
• Continuous monitoring 使用CSPM工具对云进行管理，确保遵循所有公司安全策略. 同时，这些工具在没有用户干预的情况下修复任何检测到的问题. 
• Valuable context is delivered via mapping interdependencies between cloud infrastructure, services, and abstraction layers to fully understand the source and scope of risk. 
• CSPM tools help to identify workload issues and potential attack surfaces/exposures by detecting configuration issues/deviation from best practices. 它们与本地监视和警报进行互操作，以提供有效的事件识别和升级.

How Does CSPM Work?

CSPM通过部署工具来工作，这些工具为使用它们的公司带来了各种各样的好处. By learning how the technology actually works, 用户和组织可以更深入地了解它在其他方面的适用范围 cybersecurity platforms. Ultimately, this is critical knowledge for IT, cloud, SecOps, and compliance and risk management teams. 

Of course, security automation plays a key role in boosting the efficiency of SecOps teams, cloud or not. CSPM利用自动化来识别和修复任何不利影响之前的威胁. These potential threats include those dangerous configuration errors, open IP ports, unauthorized activity, and more. It’s a proactive approach that operates on a 24/7 basis, ensuring a company’s cloud infrastructure is always protected.  

Companies successfully adopting DevSecOps understand the importance of seamlessly integrating tools from different vendors. CSPM definitely helps in this process, 为IT团队和DevSecOps团队提供了一个关于当前云安全状况的真实来源. 所有云资产的安全策略都是从单个控制台管理和执行的, which makes this tool an effective and efficient choice for many enterprises.

Key Capabilities of CSPM

CSPM工具可以提供公司整个云基础设施的全面视图. This real-time visibility includes configuration of applications and workloads, as well as other assets and configurations. 

As new cloud deployments and connections are implemented, CSPM工具会自动发现它们并分析它们的潜在威胁级别. It should be able to offer detection, logging, reports, 自动化处理与遵从性和法规标准相关的安全性. 

在严格监管的行业(如医疗保健)部署云架构的组织, energy, 和财务——应该发现CSPM解决方案能够持续实时监控，有助于解决与错误配置相关的安全问题, as well as multi-cloud governance issues across the sectors mentioned above.

Differences Between CSPM and Other Cloud Solutions

云基础设施安全态势评估(CISPA)为云安全提供了一个较早的选择. However, 它更侧重于报告功能，而不是CSPM引入的自动主动方法. As such, it’s an obsolete solution not suitable for complex cloud architectures.

Cloud workload protection platforms (CWPPs) 拥有识别和分析云环境中的工作负载的单一目标. Obviously, this approach differs from CSPM solutions, 谁负责分析基于云的基础设施的所有安全方面. Using the two tools in tandem provides an integrated solution, which takes full advantage of CSPM’s automation.

云访问安全代理(casb)在云服务提供商及其客户之间提供了一个安全层. They analyze all incoming traffic, verifying policy compliance before permitting access to the network. 典型CASB的特性集包括防火墙、恶意软件保护和数据安全性. 因为CSPM解决方案在其其他功能中具有自动策略遵从性监视功能, integrating both tools as part of a common cloud security strategy is a wise choice. 

Best Practices for Adopting CSPM

Integrating CSPM with a SIEM 平台为管理员提供了跨公司云资产的所有活动的单一视图. 这种方法可以更容易地识别和修复云环境中配置错误的资产和其他潜在漏洞.

任何CSPM解决方案与其他DevOps工具的适当集成对于成功采用新的云安全原型起着至关重要的作用. All SecOps, DevOps, 技术基础设施团队从报告和实时仪表板的通用方法中受益.

来自互联网安全中心的云基准是任何公司采用CSPM的一个有价值的目标. 这种方法有助于确保组织策略继续满足不断变化的全球云环境的不断发展的标准.

重点分析各种云安全风险，目标是优先考虑最关键的风险. Let the CSPM automatically remediate lower-priority issues, only sending alerts when critical threats are detected. 这种方法可以防止警报疲劳降低云管理团队的效率，并使他们能够专注于无法通过自动化解决的问题.
