Understanding cloud security

Cloud security is top of mind for most organizations leveraging cloud computing.

The concept is simple, but the execution is complex and everchanging. Most importantly, the risks/rewards can be immense and long-lasting.

Let’s jump into cloud security basics.

What is cloud security?

Cloud security is the full scope of people, processes, policy and technical components that go into keeping a cloud environment secure from internal and external threats. A successful cloud security approach is a shared responsibility among customers and providers, and it should protect:

  • Applications and data
  • Equipment
  • Facilities
  • Access to all of the above

Why is cloud security important?

Cloud security is important because it protects organizational assets, which helps ensure the business interests and goals of cloud-enabled organizations are being met. An organization may be motivated to protect its cloud environment for a variety of reasons, all of which revolve around the principle that secure data is good business. Motivations may include:

The benefits of good cloud security

Multiple layers of defense

Standard best practices require cloud security to adopt a defense-in-depth strategy. This well-known approach to securing important assets, such as cloud data, means cloud providers deploy numerous, diverse defense tactics to provide full, dynamic coverage against attacks — both internal or external.

Automated cloud monitoring

Innovative cloud providers use cloud automation to provide best-in-class security. Automation helps detect misconfigurations, monitor and enforce security protocols, drive updates, audit access logs and evolve to continually better meet an organization’s risk management goals.

Disaster recovery preparedness

A cloud provider should protect and back up data so it can be replicated in more than one place. This ensures your data in the cloud is available even if the datacenter site experiences a disaster, such as a flood, power outage or fire, as well as during a cyberattack. Geographically dispersed cloud datacenters help here.

High data availability

Cloud computing security provides redundant configurations for critical systems and makes your critical data and content continuously available, regardless of attacks or disasters.

Data segmentation

Ideally, data segmentation across on-premise and cloud resources can help separate data and/or workflows. This can help prevent lateral attacks and improve compliance efforts. Additionally, it provides the opportunity to assign different security parameter and authentication rules depending on the data segment. In practice, this means data sets or content can only be accessed by users and hosts specifically approved to do so.

Immediate incident response

Cloud infrastructure with incident response capabilities such as automated cloud monitoring can save compliance fines, alert the team to threats before they succeed and speed security responses.

Reputation protection

Data breaches cost organizations more than just time and money to respond to the attack. For those whose data gets exposed, their reputation and customer trust take a hit, too.

Compliance

Cloud security infrastructure should meet all of your compliance needs, from SOC 2 to HIPAA, GDPR and ISO. Most cloud providers leverage a shared responsibility model to deliver cloud compliance.

Scalability

Modern cloud environments can quickly scale security updates and protocols to keep your data safe against emerging or detected threats.

Challenges to cloud security

Misconfiguration/lack of cloud expertise

Cloud misconfiguration is the No. 1 cloud vulnerability, according to the National Security Agency (NSA). While the industry-wide cloud expert shortage contributes to this (there aren’t enough cloud experts to properly service all the cloud needs in the market), misunderstandings around shared responsibility arrangements also impact cloud security.

Unfortunately, cloud misconfiguration is a widespread problem that even unsophisticated bad actors can take advantage of.

Identity and access management

Excessively privileged cloud identities allow bad actors to access the cloud environment and wreak havoc. Least-privilege protocols are needed to limit the systems that users and administrators can access to limit the scope of damage if credentials get compromised.

Cyberthreats

Brute force attacks, ransomware, supply chain attacks, falsified credentials — all these types of cyberattacks can become a threat to cloud security if best practices aren’t followed.

Infrastructure weaknesses

For cloud datacenters, organizations offload the responsibility of facility and server oversight to their cloud provider. Some organizations may feel they are losing control, but proven cloud providers such as Amazon Web Services (AWS) can offer a much greater level of data protection than less specialized organizations trying to do their own cloud management.

Disorganized assets

If organizations lack a clear view of the assets they have in the cloud, it’s difficult to keep them all secure.

Speed of the cloud

Cloud service providers are innovating, modifying, updating and replacing their services with incredible speed. So quickly, in fact, that it can be difficult for even the most skilled cloud expert to keep up. New functionality is typically a strength in your technology, but in this case the added complexity can present as a security challenge as well.

Security differences in SaaS, PaaS and IaaS

Cloud computing is typically delivered via three models — Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).

Security responsibilities differ among the three.

IaaS security

Major cloud infrastructure-as-a-service providers, such as AWS, Microsoft Azure or Google Cloud, lead the industry in cloud security. They have the expertise, physical structures and cloud security best practices in place to secure the cloud infrastructure they provide. IaaS partners, generally, are responsible for datacenters, hardware, network and failover.

PaaS security

PaaS solutions such as AWS Elastic Beanstalk, Salesforce Platform and Hyland’s Alfresco Digital Business Platform are cloud-native. PaaS customers accept a shared security responsibility model in which they, as a customer, must secure their data, application(s) and user accessibility; the PaaS provider is responsible for securing physical infrastructure and operating systems.

SaaS security

A SaaS solution such as Salesforce, SAP or Hyland’s OnBase provides security for the application. If the application is deployed with an IaaS partner, the IaaS partner holds the responsibility for keeping cloud infrastructure safe, as noted above. If the SaaS application is deployed on-premise or in a self-managed cloud environment, the responsibility for cloud security remains with the organization that subscribes to the application.

What to look for in a cloud services provider

Any time an organization partners with a third party, it’s important to vet them carefully. Their track record, customer retainment percentage, reputation in the industry, customer success support and more are all important.

When it comes to cloud security, the vetting is critical to both everyday and long-term success.

Use a universally recognized questionnaire

Luckily, there’s an industry standard for evaluating cloud services partners. The Standardized Information Gathering (SIG) Questionnaire was developed by Shared Assessments, an organization dedicated to developing the best practices, education and products for third-party risk assurance.

Most reputable cloud providers will have this questionnaire completed and ready to share. It covers 19 “domains” within a service provider’s environment:

  • Access control
  • Application security
  • Asset and information management
  • Cloud hosting services
  • Compliance management
  • Cybersecurity incident management
  • Endpoint security
  • Enterprise risk management
  • Environmental, social, governance (ESG)
  • Human resources security
  • Information assurance
  • IT operations management
  • Network security
  • Nth party management
  • Operational resilience
  • Physical and environmental security
  • Privacy management
  • Server security
  • Threat management

Cloud security for digital transformation

Cloud security requirements and importance will only grow as more organizations migrate to and operate in the cloud, whether with IaaS, PaaS or SaaS deployments.

Organizations must take due diligence to prevent unauthorized access, data theft and other security issues. Selecting the right solution partners and providers is paramount.
