In a survey report in March 2022, 80% of organizations store sensitive data in the cloud, 53% of respondents faced a cyber attack on their cloud infrastructure within 12 months, and 49% of cyber professionals believe that cyberattack leads to unplanned expenses to fix. Nowadays, businesses adopt the cloud rapidly due to its several benefits, such as cost savings, scalability, and flexibility. Adopting cloud infrastructure also includes some cyber threats and other risks. It is essential to use the comprehensive Cloud Security Strategy and Managed Cloud Security to cover all the aspects of cloud security. Physical Security, network security, data security, application security, compliance and regulatory Security, disaster recovery, and business continuity planning are a few of the several aspects of cloud security. There are specific best practices, instruments, and methods for securing cloud resources for each security type. This article will give an in-depth description of the many types of cloud security and analyze best practices for implementing such security measures. Additionally, we will look at common cloud security concerns, discuss how to mitigate them, and highlight new advances and trends in cloud security. After reading this article, you should better understand how to safeguard the cloud resources used by your Company and maintain the Security and privacy of your data. Physical Security secures physical assets, such as data centers, servers, and other hardware, from theft. Additionally, physical security measures in the cloud frequently include access control systems, surveillance cameras, motion detectors, and other physical barriers to prevent illegal data center or server room access. These precautions can prevent physical assaults like theft, vandalism, and sabotage and identify and address security issues. Watch the video below on how Google Cloud Platform and other Cloud Providers prevent these types of assaults: Happily, physical Security is the responsibility of cloud service providers such as Amazon Web Service, Microsoft Azure, Google Cloud, etc..… However, you are responsible for which physical location you want to store your data. Network security prevents unwanted access, manipulation, disruption, or destruction of the network infrastructure and communication channels. Network security in cloud computing implies protecting both user and cloud provider networks. A secure, reliable, and scalable network infrastructure is a requirement for cloud service providers. They must also employ firewalls, intrusion detection and prevention systems, virtual private networks (VPNs), and other security technologies to defend their network from threats. Network isolation for each customer is the most effective way cloud providers ensure network security. Implementation of VPC (Virtual Private Cloud), VPN (Virtual Private Network), using NACL (Network Access Control Lists), and security groups that act as a firewall to control inbound and outbound traffic are some ways to isolate the network. On the other hand, Users are responsible for their networks being safe and that they can safely connect to the cloud provider’s network. To safeguard their data and stop illegal access, they must install security measures, including encryption, authentication, access control, and monitoring. Data security in cloud computing refers to protecting the data processed, sent, or stored there. Cloud providers must adopt several security measures to secure their client’s data, including encryption, access control, backup and recovery, and data loss prevention (DLP). Additionally, they provide a robust and resilient infrastructure to prevent data loss. To ensure the high availability and durability of client data, Cloud providers have built their infrastructure with many layers of redundancy and data security mechanisms, such as Data Replication, Backup, and Restore, Data Encryption, Multiple Availability Zones (Multi AZs), Multi-Region Replication, Disaster Recovery, Monitoring and Logging, Compliance and Regulatory.

In order to safeguard their data in the cloud, users must also employ data security procedures. Companies must use access control to restrict who can access their data, encrypt it before uploading it to the cloud, and watch for unwanted access or alteration. User identities and their access to resources and services are managed by Identity and Access Management (IAM). IAM in cloud computing refers to administering user accounts, roles, privileges, and authentication protocols. Cloud providers must implement IAM to guarantee that only authorized users can access their resources and services. They must also support single sign-on (SSO) and multi-factor authentication (MFA) to increase Security. To control user identities and access, users must adopt IAM. Users must be authenticated via Multi-Factor Authentication (MFA), have roles and permissions assigned, and have user accounts created. Regarding applications, cloud computing has many security threats, such as malware, viruses, and hackers. Application security is the responsibility of both Cloud Service Providers and Users. Cloud Service Providers implement firewalls, intrusion detection and prevention systems, and code-scanning tools to detect and prevent application-level attacks. Similarly, you or the users must use secure coding practices and code-scanning tools to detect vulnerabilities and implement security controls such as firewalls and access control. Critical company operations are guaranteed to continue during a disruption or disaster thanks to business continuity and disaster recovery (BCDR). In cloud computing, BCDR refers to the preparation and execution of measures to avoid, lessen the impact of, and recover from interruptions or disasters. Cloud service providers must put BCDR policies into place to guarantee that their services continue to be accessible and dependable even in the event of catastrophes like natural disasters or cyberattacks. To ensure that their business activities can continue during a disruption or disaster, users must also create BCDR plans. Companies must consider failover, redundancy, and data backup and recovery to ensure their organization can run smoothly. Compliance and Regulatory Security Comply with separate regulations that control data privacy and security, including HIPAA, PCI-DSS, and GDPR. Cloud computing compliance and regulatory security ensure that the cloud provider and the user comply with various laws and regulations. Cloud providers must adopt various security controls and procedures to guarantee that their services meet various requirements. When using cloud services, users must abide by several rules. To ensure their operations and data conform, they must implement security controls and procedures after fully understanding the compliance requirements. As we already mentioned earlier, there are lots of security threats in cloud computing. The security responsibilities are divided into Cloud Service Provider and Customer based on the threats. Cloud Service provider’s responsibilities are: Responsible for Infrastructure and Physical Security Securing the hypervisor and host operating system Responsible for Network infrastructure protection Responsible for the Availability and durability of Cloud services Responsible for data encryption in transit and at rest between cloud services In the event of a security issue, incident response, and forensics Similarly, Users’ responsibilities include: Responsible for their data and application protection Establishing network access control lists and security groups (ACLs) Roles and permissions configuration in identity and access management (IAM) Responsible for Monitoring and logging AWS resources and applications Adherence to applicable laws and requirements Keeping track of and managing the workloads’ and applications’ security Although cloud computing has numerous advantages, security is still a major issue for many businesses. In this article, we covered the seven forms of cloud computing security that businesses should be aware of to keep their data secure. These security categories include compliance and regulatory security, identity and access management, network security, data security, application security, physical security, business continuity and disaster recovery, and data security. By implementing these security measures, organizations may guarantee their cloud operations are safe, dependable, and legal.1: Physical Security
