Critical security risks in the cloud environment?

The importance of cloud security has increased over the years. Numerous enterprises then opted for cloud adoption when managing their data and applications. Unfortunately, many 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, the cloud environment’s vulnerability to data breaches, as well as other critical security risks, has increased. Business entities may leave their data open to criminal exploitation when they fail to do their due diligence for security needs. 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 how security is implemented and monitored.

Automation in DevOps

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

Weak access management

Organizations must have a dedicated framework for managing access control when they adopt the cloud. In most cases, they use a standard free-for-all arrangement that allows users more access than they need for their work. This can enhance the chances of internal and external security risks as cyber criminals may have access to the user’s privileges.

Inconsistent security features in complex environments

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

Compliance requirements

Even though most 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. Companies must 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, higher levels of authentication are needed to gain access. Employees need to take ownership of security and use better password policies.
   
2. Zero-trust network security controls. The organization’s mission-critical applications and assets should be kept within strategically isolated parts of the cloud network, such as virtual private cloud systems. By segregating sensitive workloads from those 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 monitor 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 (WAF). A WAF makes scrutinizing traffic from servers and web applications easier. It can also strengthen endpoint security to avoid breaches by monitoring and alerting administrators regarding suspicious behavior.
   
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 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

Cybercriminals always seek ways to attack endpoints and infiltrate servers while avoiding notice. Therefore, businesses must invest in endpoint security 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 user activity monitoring.
