Cloud Security

Organizations of all sizes are increasingly reliant on cloud computing. This increased usage makes cloud computing platforms a target for cyber-attacks.

Integrating cloud into your existing enterprise security program is not just adding a few more controls or point solutions. It requires an assessment of your resources and business needs to develop a fresh approach to your culture and cloud security strategy.

Cybersecurity in cloud computing environments is a multi-faceted endeavor, involving best practices in user access and privileges, hardware and software security, virtualization, firewalls, and other processes used to protect data and infrastructure.

What is Cloud Security?

Cloud computing security or, more simply, cloud security refers to a broad set of policies, technologies, applications, and controls utilized to protect virtualized IP, data, applications, services, and the associated infrastructure of cloud computing.


A common misconception with cloud security is that cloud service providers are responsible for security. That’s simply not the case. A good rule of thumb is while cloud providers are responsible for the security of the cloud, companies must secure what’s in the cloud. To put it another way, cloud security is a shared responsibility. And as many in the security community put it, your responsibilities vary by your cloud service model, whether software-as-a-service (SaaS), platform-as-a-service (PaaS), or infrastructure-as-a-service (IaaS).

Best Practices

Cloud security is constantly evolving, but a handful of best practices have remained constant for ensuring the security of cloud environments. Organizations that have existing cloud solutions in place or are looking to implement them should consider these tips and tools to ensure that sensitive applications and data don’t fall into the wrong hands.

  • Understand Your Shared Responsibility Model
    In a private data center, the enterprise is solely responsible for all security issues. But in the public cloud, things are much more complicated. While the buck ultimately stops with the cloud customer, the cloud provider assumes the responsibility for some aspects of IT security. Cloud and security professionals call this a shared responsibility model.
  • Ask Your Cloud Provider Detailed Security Questions
    In addition to clarifying shared responsibilities, organizations should ask their public cloud vendors detailed questions about the security measures and processes they have in place. It’s easy to assume that the leading vendors have security handled, but security methods and procedures can vary significantly from one vendor to the next.
  • Deploy An Identity And Access Management Solution
    The fourth-biggest threat to public cloud security identified in CloudPassage’s report is unauthorized access. While hackers’ methods of gaining access to sensitive data are becoming more sophisticated with each new attack, a high-quality identity and access management (IAM) solution can help mitigate these threats.
  • Train Your Staff
    To prevent hackers from getting their hands on access credentials for cloud computing tools, organizations should train all workers on how to spot cybersecurity threats and how to respond to them. Comprehensive training should include basic security knowledge like how to create a strong password and identify possible social engineering attacks as well as more advanced topics like risk management.
  • Establish And Enforce Cloud Security Policies
    All organizations should have written guidelines that specify who can use cloud services, how they can use them, and which data can be stored in the cloud. They also need to lay out the specific security technologies that employees must use to protect data and applications in the cloud.
  • Secure Your Endpoints
    Using a cloud service doesn’t eliminate the need for strong endpoint security—it intensifies it. New cloud computing projects offer an opportunity to revisit existing strategies and ensure the protections in place are adequate to address evolving threats.
  • Encrypt Data In Motion And At Rest
    Encryption is a key part of any cloud security strategy. Not only should organizations encrypt any data in a public cloud storage service, but they should also ensure that data is encrypted during transit—when it may be most vulnerable to attacks.
  • Use Intrusion Detection And Prevention Technology
    Intrusion prevention and detection systems (IDPS) are among some of the most effective cloud security tools on the market. They monitor, analyze, and respond to network traffic across both on-premises and public cloud environments. When they encounter signature-based, protocol-based, or anomaly-based threats, IDPS solutions add them to a log, alert administrators to unusual activity, and block the threats so admins have enough time to take action.
  • Double-Check Your Compliance Requirements
    Organizations that collect personally identifiable information (PII) like those in retail, healthcare, and financial services face strict regulations when it comes to customer privacy and data security. Some businesses in certain geographic locations—or businesses that store data in particular regions—may have special compliance requirements from local or state governments as well.
  • Consider A CASB Or Cloud Security Solution
    Dozens of companies offer solutions or services specifically designed to enhance cloud security. If an organization’s internal security staff doesn’t have cloud expertise or if the existing security solutions don’t support cloud environments, it may be time to bring in outside help. Cloud access security brokers (CASBs) are tools purpose-built to enforce cloud security policies. They have become increasingly popular as more organizations have started using cloud services. Experts say that a CASB solution may make the most sense for organizations that use multiple cloud computing services from several different vendors. These solutions can also monitor for unauthorized apps and access too.
  • Conduct Audits And Penetration Testing
    Whether an organization chooses to partner with an outside security firm or keep security teams in-house, experts say all enterprises should run penetration testing to determine whether existing cloud security efforts are sufficient to protect data and applications.
  • Enable Security Logs
    In addition to conducting audits, organizations should enable logging features for their cloud solutions. Logging helps system administrators keep track of which users are making changes to the environment—something that would be nearly impossible to do manually. If an attacker gains access and makes changes, the logs will illuminate all their activities so they can be remediated.
