A collection of procedures and tools that reduce security risks from the outside as well as the inside of the company are included in cloud security. This is particularly crucial as companies integrate cloud services and tools into their infrastructure.

With the same objective of promoting innovation, phrases like “cloud computing” and “digital transformation” have proliferated in business discourse. Organizations must, however, strike a balance between infrastructure security and productivity when they use these technologies to streamline their operations. Even while contemporary technologies offer more scalability than on-premises infrastructure, if cloud computing is not safely adopted as the primary environment, there may be repercussions.

Businesses must have a thorough understanding of how to integrate cloud computing with the finest security technologies for their infrastructure in order to strike the correct balance.

What makes cloud security crucial?

According to the Shared obligation Model, cloud security falls into distinct areas and is a shared obligation between the consumer and the service provider. These include particular obligations of the client and provider under various service types (IaaS, PaaS, SaaS). These service models assist firms in lessening the burden of managing IT infrastructure, which is a challenge for many organizations.

It is crucial to comprehend the security needs in order to safeguard data when implementing cloud computing infrastructure. Organizations are still in charge of data security even though cloud providers place a high priority on server data integrity. Cloud service providers must take proactive steps to reduce governance and compliance risks related to customer information as security threats continue to rise.

What makes cloud security crucial?

No matter the size of the company, cloud security is a crucial subject. Many sectors are benefiting from cloud technology, but widespread adoption requires robust security measures. To guarantee business continuity, it is essential to install best-in-class cloud security solutions, regardless of whether the environment is public, private, or hybrid.

Top Cloud Security Challenges

The absence of security corridors in public clouds, particularly when using contemporary strategies like serverless architectures, CI/CD, and transient assets. The following are the main cloud security issues that enterprises are now facing:

• Increased attack surface: Public cloud settings with inadequate protection for ingress ports attract hackers and can result in threats including malware, ATOs, and Zero-Day assaults.
• Absence of monitoring and visibility: The Infrastructure layer in the IaaS paradigm is entirely in the authority of cloud service providers, which restricts client visibility. This restriction prevents the efficient identification and measurement of cloud assets and is prevalent in both PaaS and SaaS cloud models.
• Changing workloads: Traditional security methods are challenged by the rapid and scalable dynamic provisioning and decommissioning of cloud assets, which makes them unable to enforce protection requirements in a complex environment with dynamic workloads.
• Automation, DevOps, and DevSecOps: Adopting a fully automated DevOps CI/CD process requires organizations to incorporate suitable security measures into code and templates as soon as they are created. Making security-related adjustments after deployment can prolong product launch delays and jeopardize an organization’s security.
• Privilege and Security Key Management: Inadequate management of cloud service users can result in the granting of needless privileges, which can be dangerous for security. Login sessions are vulnerable to security threats due to improperly set security keys and privileges at the application level. Complex settings: Methods and solutions that smoothly connect public and private cloud providers with on-premises infrastructure, including edge security for organizational branches, are necessary for consistent cloud security management in hybrid and multi-cloud environments.
• Compliance and governance: Customers are also in charge of regulatory compliance, even if cloud providers are required to adhere to national (Decree 53/2022/ND-CP, Decree 13/2023/ND-CP) and international (PCI-DSS, ISO 27001/27017/27018) standards. Compliance auditing is more challenging due to manageability issues and complicated cloud infrastructures, necessitating the use of technologies for ongoing audits and real-time misconfiguration notifications. Shadow IT and Access Management: Access point management in cloud environments can be difficult, particularly in the absence of stringent BYOD (Bring Your Own Device) regulations, which increases the possibility of unauthorized access from personal devices and access points.
• Misconfiguration: A large percentage of breaches in cloud systems are caused by unintentional insider threats resulting from improperly configured assets. Not changing default passwords or avoiding the proper privacy settings are examples of misconfigurations.

Essential Components of a Sturdy Cloud Security Solutions

Although top cloud service providers like AWS, Google Cloud, and VNG Cloud frequently offer a variety of security capabilities, third-party security solutions are also crucial for shielding companies against intrusions, data leaks, and targeted attacks. In accordance with industry standards, centralized management and granular control based on policies are provided by integrated cloud/third-party security solutions.

Essential Components of a Sturdy Cloud Security Solutions

• Granular Authentication Management and Identity and Access Management (IAM): Implement granular IAM controls in a variety of intricate settings. Roles and groups that facilitate simpler IAM modifications in accordance with business needs. Use strong IAM features to implement least privilege access controls, including provisioning timeouts and strong passwords.
• Model of Zero-Trust Network Security: Use virtual private clouds (VPCs) to deploy important resources in different settings. Implement granular security policies on subnet ports and use subnets for micro-segmentation. To personalize access, use static UDR (User-defined Routing) setups and dedicated WAN links in hybrid architectures.
• Policies and Procedures for VM Protection: During virtual machine deployment, use Cloud Security Posture Management (CSPM) to ensure uniform administration and rule enforcement. Look for configuration deviations and, if you can, automatically fix them using procedures like software upgrades and change management.
• New WAF Firewall Technology: Use a new generation of WAF engines to safeguard all applications, particularly cloud-based distributed apps. Deploy closer to microservices applications, automatically update WAF rules based on traffic, and thoroughly inspect and manage traffic to and from web application servers.
• Superior Data Security: Put advanced data security mechanisms in place, such as secure file sharing, ongoing legal risk monitoring, encryption at all transit tiers, and data storage upkeep. Find and remove isolated groups and resources that are not configured correctly.
• Real-time Threat Detection: Gather intelligence using third-party cloud security solutions to identify and address known and new threats instantly. Combine cloud logs and contrast them with information from both internal and external sources. For quick remediation, use AI anomaly detection to identify unknown threats. This should be followed by real-time forensic investigation and alerts about intrusions and policy violations.

4 Common Types of Cloud Security

• The implementation of policy-based security procedures for user access, including on-premises and cloud services, is made possible by Identity and Access Management (IAM) technologies and services. IAM’s primary duties include establishing user digital identities, closely monitoring them, and enforcing limitations on data exchanges.
• Cloud data security tools are offered by Data Loss Prevention (DLP) services. DLP safeguards data while it is in use or in transit by using remediation warnings, data encryption, and other preventative measures.
• SIEM Solutions: In cloud environments, SIEM (security information and event management) offers a complete security orchestration solution that automates threat detection, monitoring, and response. SIEM assists IT teams in implementing network security protocols and promptly addressing possible attacks by using AI technology to analyze log data across various platforms.
• Business continuity and disaster recovery: Data breaches and outages can still happen even with precautions. In cloud computing security, backup and disaster recovery solutions are crucial because they give businesses the resources, services, and procedures they need to quickly recover data and carry on with regular business activities in the case of a system breach or other disruption.

How to Approach Cloud Security?

Every firm will have a different approach to cloud security, which is dependent on a variety of criteria. Nonetheless, a set of best practices for creating a safe and robust cloud computing paradigm has been delineated by the National Institute of Standards and Technology (NIST).

Organizations can self-evaluate their security readiness and put the right procedures and recovery in place by following NIST’s suggested actions. The five fundamental components of cybersecurity identified by NIST—Identify, Protect, Detect, Respond, and Recover—are in line with these guidelines.

CSPM is the state-of-the-art technology that facilitates the use of the NIST cybersecurity paradigm. Misconfiguration is a prevalent issue in cloud computing environments that is addressed by CSPM solutions. Enterprise or cloud provider-based misconfigured cloud infrastructure might expose users to security risks. In order to overcome these obstacles, CSPM assists businesses in putting essential cloud security components into place and deploying them, such as IAM, traffic monitoring, threat response, risk mitigation, regulatory compliance management, and digital asset management.

Zero-Trust Cloud Security Model

John Kindervag’s 2010 introduction of the Zero Trust concept, which challenges the conventional method of automatically trusting objects within or outside the network, has completely changed the field of cloud security. Verification-authorization, ongoing auditing, and safeguarding everything are instead encouraged by Zero Trust.

By restricting user access to only the resources required for the job, Zero Trust places a strong emphasis on the Least Privilege governance approach. Additionally, it motivates programmers to consistently protect web-based applications. For instance, an application may become susceptible to hackers and illegal database access if port blocking is not applied regularly or if superfluous permissions are granted.

Additionally, to improve the granularity of cloud network security, Zero Trust networks employ micro-segmentation. Micro-segmentation isolates workloads, secures content inside each zone, and applies policies to safeguard traffic between zones by establishing secure zones in the data center and implementing it on the cloud architecture.
