With ever-increasing incidents of data thefts and security breaches, it has become essential for companies to use efficient endpoint security for all their endpoints to prevent any loss of data. Security breaches can lead to billions of dollars worth of loss, not to mention the negative press in the business world.

This is why it is vital for companies to use cutting-edge endpoint security technology for their cloud computing systems. If you are working with cloud systems in any capacity, you must also use cloud security to safeguard data breaches.

However, before you develop a good understanding of cloud security, the first and most important step is learning about cloud computing and its essential properties.

What is cloud computing?

Cloud computing can be best described as a range of hosted services offered through the internet. It replaces the need to store all computing infrastructure in a physical server environment, a physical computer or an on-premises data center. Cloud computing works with off-site hardware for hosting different types of services and encompasses software systems and storage solutions.

This flexible cloud model offers a range of strategic benefits for the users, including:

  • Easy scalability
  • Quick start deployment
  • Reduced costs for initial setup and long-term use.

When an organization has extensive privacy and compliance requirements, it can work with hybrid cloud infrastructure, which makes use of both cloud and physical computing ecosystems.

Because cloud computing works very differently from on-site hosting systems, it is necessary to protect the cloud environment using cloud security infrastructure. Through cloud security, it is possible to deal with the privacy and cybersecurity challenges posed by the cloud environment.

Cloud security involves everything used to safeguard sensitive data stored within the cloud. Using a variety of techniques, procedures, methods and controls, cloud security protects cloud applications and infrastructure from any kind of online abuse or unauthorized access.

Some cloud security aspects require more effort by the cloud customer than what cloud service providers can offer. This is particularly true for zero trust cloud architecture.

Endpoint security

Endpoint security has to do with the processes used for securing endpoints like desktops, laptops, servers and mobile devices from possible malware, unauthorized access and all other kinds of cybersecurity threats. As more and more companies work with cloud computing, endpoint security has increased in importance as it allows users to protect their cloud-based applications and data.

Critical security risks in the cloud environment?

The importance of cloud security has increased over the years. In that time, numerous enterprises have opted for cloud adoption when managing their data and applications. Unfortunately, many types of security challenges emerge while companies invest in cloud solutions. Some of these challenges include:

A more widespread threat landscape

Since many people use public cloud environments nowadays, this has increased the vulnerability of the cloud environment to data breaches as well as other critical security risks. When business entities fail to do their due diligence for security needs, they may leave their data open to criminal exploitation. In many instances, companies may not even realize their data has been stolen.

Lack of control over cloud security services

A major reason for the popularity of cloud adoption is that cloud service providers often handle security management, maintenance and upgrades. Even though this is a major benefit, it can severely limit the scope of an organization to exercise control over the way security is implemented and monitored.

Automation in DevOps

Cloud hosting brings with it the option to automate most of the continuous integration/continuous delivery (CI/CD) processes and DevOps that organizations employ to streamline their operations.

Weak access management

When organizations opt for cloud adoption, it is vital that they have a dedicated framework for managing access control. In most cases, they use a standard free-for-all arrangement that allows users more access than they actually need for their work. This can enhance the chances of security risks both internally and externally as cyber criminals may have access to the privileges of the users.

Inconsistent security features in complex environments

Numerous organizations work with a hybrid cloud environment or a multi-cloud environment, which uses several public and private cloud providers along with on-premise solutions. Such a situation can give rise to inconsistent use of security protocols, thus enhancing the chances of successful cyberattacks.

Compliance requirements

Even though a majority of the well-known cloud providers have tried to get security certifications for well-known cybersecurity frameworks, customers are still accountable for ensuring that their security systems and processes comply with major security protocols.

Six pillars of cloud security

Even though there are numerous differences between traditional security and cloud security, organizations can boost their security parameters against cyber threats in the cloud. This is why companies need to exercise due diligence when securing their cloud systems, just like in on-premises environments.

These six pillars of cloud security are crucial for securing the cloud:

  1. Secure access controls. Implementing secure IAM protocols creates a robust security framework. Team members should only have the level of access to assets, systems and application programming interfaces they need to carry out their job responsibilities. When privileges increase, there should be higher levels of authentication needed to gain access. The employees need to take ownership of security and also use better password policies.
  2. Zero trust network security controls. The mission-critical applications and assets used by the organization should be kept within strategically isolated parts of the cloud network. These can be virtual private cloud systems. By segregating the sensitive workloads from the ones that do not need data security protocols, it is possible to enforce micro-segmentation with strict security policies.
  3. Change management. By working with change management protocols offered by the cloud security providers, it is possible to manage change and use compliance controls whenever changes are requested. This should also be done when new servers are provisioned or sensitive assets get changed or moved. Change management applications offer auditing functionality to users, which can help in monitoring unusual behavior and possible deviations from the protocol. This means the organization can investigate the problem and trigger automatic mitigation to correct the issue.
  4. Web application firewall. A web application firewall (WAF) makes it easier to scrutinize traffic going in and out of servers and web applications. By monitoring and alerting administrators regarding any suspicious behavior, a WAF can strengthen endpoint security to avoid breaches.
  5. Data protection. Enhanced data security is possible when an organization encrypts its data at all layers. There should also be security protocols for communication applications, file sharing and other areas within the environment where the organization stores, uses and transmits data.
  6. Continuous monitoring. Numerous cloud security providers offer valuable insight into cloud-native logs, enabling comparison with internal logs taken from other security tools like asset management tools, vulnerability scanners, change management tools and insights from external threat intelligence. Such efforts increase the chances for rapid incident response and make it easier to implement remediation workflows.

Cloud-based endpoint security keeps your business secure

Cyber criminals are always looking for ways to attack endpoints and infiltrate servers while avoiding notice. Therefore, it is crucial that businesses invest in endpoint security so that they are able to prevent breaches.

Through endpoint security, it is possible to benefit from better data protection and encryption features that prevent criminals from achieving their nefarious purposes. Implementing cloud security features can secure data access, prevent infiltration and deliver benefits like better monitoring of user activity.
