Businesses moving to the cloud must take on new responsibilities, develop new skills, and implement new processes. The first step to improving the security of cloud computing is to assume that there is no security.
Cloud computing has changed the way companies work and will continue to disrupt traditional business models. According to research firm IDC, public cloud spending will more than double by 2023, from $ 229 billion this year to nearly $ 500 billion.
It's no secret that companies moving their businesses to the cloud can significantly reduce costs and increase efficiency. Users can launch cloud computing instances in minutes, and can expand or reduce computing resources as needed, while paying only for the products and resources they use, while avoiding high upfront hardware costs and maintenance costs.
Opportunities and risks will multiply
But don't forget. Businesses are storing their data on third-party servers, which, although under control, are still owned by third parties. Even if the cloud computing service provider's environment is highly secure, the content (applications and data) in the cloud remains the responsibility of the enterprise itself.
Many companies have put cloud computing security on the board's agenda because its impact can have a serious impact on corporate reputation and shareholder value. Enterprise data moved to the cloud platform beyond traditional boundaries, resulting in an expanded attack surface. As more and more sensitive information is stored in the cloud platform, the resources in the cloud platform become more and more the target of cyber criminals.
Prepare for new threats
As businesses move to the cloud, they will have to assume new responsibilities, develop and adjust processes to deal with many unknown threats. The secret to improving cloud computing security is to assume that there is no security at all when assessing the overall security posture.
Public cloud security involves multiple elements, so it's difficult to figure out where to start. If your business is already on a cloud platform or is planning to migrate to a cloud platform, there are five best practices you can follow to protect its public cloud adoption.
1. Know your responsibilities
The security of cloud computing is based on a shared responsibility model. Cloud computing providers have a responsibility to protect the physical network and secure the infrastructure, and businesses have a responsibility to protect their data, applications, and content, including elements such as user access and identity. Keep in mind that businesses need to be responsible for managing and protecting everything placed on the cloud.
2.Integrate compliance
Compliance is one of the main drivers of the demand for next-generation cloud computing security services. The only way to ensure compliance with new and forthcoming regulations is to integrate regulatory compliance into the day-to-day operations of the enterprise, taking into account real-time snapshots of the network topology and real-time alerts on policy changes. From the auditor's standpoint, consider all the items they require when reviewing the network and actively incorporate these reports into their daily work.
3.Automated defense
Automation is a key component of cloud computing security. Security audits, controls, patches, and configuration management, all of which can be automated and can help reduce risk. As long as the right tools and processes are in place, automation can significantly reduce the risk of human error, which is critical for managing change on a large scale and preventing security breaches. A secure, automated cloud platform can help monitor the network in real time and provide businesses with the ability to respond quickly to threats.
4. Protect the environment as soon as possible
For organizations, strict security controls must be maintained even in a development and quality assurance (QA) environment. By embedding appropriate controls in application development, early adopters are introducing security early in the life cycle. The new security approach promotes the concept of security by design, checking source code for vulnerabilities even during development. Regardless of the security measures the company takes, it needs to be ensured that a similar approach is adopted in its internal environment.
5.Implement on-premises learning
Although cloud computing is a major change in technology and may look like a completely different environment, the basic principles of security remain the same. As with traditional on-premise networks, it is also important to adopt the same approach on cloud platforms. For enterprises, using firewalls, servers, and endpoint protection solutions to protect the network, servers and endpoints are critical. These solutions can monitor corporate traffic, prevent unauthorized access, and protect corporate data assets on the cloud platform from destruction, infection, or data loss. Endpoint and email security keeps corporate devices current while preventing unauthorized access to cloud computing accounts. As businesses migrate to the public cloud, they must maintain their own on-premise experience.
