When data is stored in the cloud, organizations may feel they have less visibility and control over their data. This can make it difficult to monitor and manage security effectively.
Compliance Complications
Maintaining compliance with industry regulations can be more complex in the cloud due to the dynamic nature of the cloud environment and the involvement of third-party service providers.
Data Privacy
Protecting the privacy of sensitive data in the cloud can be challenging. Data may be stored in different locations around the world, each with its own privacy laws and regulations.
Threat Detection and Response
The cloud environment can be more complex and dynamic than traditional IT environments, making threat detection and response more challenging. Cloud-based TDR solutions have been growing to answer the demands of the industry.
Misconfigurations
As per the statements of 59% of cloud users, misconfigurations pose a significant risk to public cloud security. Nineteen percent of cloud users who had a security problem in the past year did so because of an incorrectly configured resource or account.
Insufficient Cloud Security Expertise
There is a global capacity shortage in cybersecurity (specialists and throughout the wider workforce), and as new technologies emerge, the skills gap in delivering cybersecurity will widen.
Insecure APIs
APIs are often used to interact with cloud services, making them a potential target for attackers.
Account Takeovers
Account takeover (ATO) is an increasingly popular attack style in the cloud realm. It’s when an attacker tries to gain access to a user so that it may receive more access over time or infiltrate another part of the organization using the account.
Cloud Vulnerabilities
As companies move their workloads to the cloud, these environments contain larger volumes of sensitive data, making them more vulnerable to attacks.
14 Cloud Security Management Best Practices
Security management in cloud computing is a broad field that encompasses various aspects. Here are some best practices for each of the key components:
Access Control and Identity Management
Access control and identity management are crucial aspects of cloud security best practices. They ensure that only authorized individuals have access to your cloud resources. Best practices include adopting a Zero Trust approach to security, identifying and protecting high-value data, enforcing a strong password policy, using Multi-Factor Authentication (MFA), automating workflows, adopting the principle of least privilege, enforcing just-in-time access where appropriate, and leveraging both role-based access control and attribute-based access control policies.
Data Encryption
Data encryption is another essential aspect of cloud security best practices. To stop unwanted access, data must be transformed into a code. Best practices include using robust encryption algorithms like AES, RSA, and Twofish, keeping encryption keys secure, and using multi-factor authentication.
Regular Auditing and Monitoring
Regular auditing and monitoring are necessary to identify any potential security threats or breaches. Best practices include configuring tables used for debugging, troubleshooting, and auditing as Basic Logs, configuring data retention and archiving, and regularly analyzing collected data to identify trends and anomalies.
