A Robust Security Framework against cloud challenges!

  • Cloud is continuing as the go-to solution and a key enabler for organizations to complete their digital transformation. They are also evolving as a top c-suite agenda as organizations are on the path of a more holistic end-to-end digital conversion. Besides the array of benefits that the cloud clings, understanding the security requirements for maintaining data in the cloud is also vital. While third-party cloud computing providers hold the management responsibility of the infrastructure, data asset security and accountability won’t necessarily divert along with it. And that is where cloud security becomes a top ask in front of cloud businesses and users.
  • Cloud security isn’t that far from the prevailing traditional IT systems security. Major security concerns like access control, exposure to attacks, and availability impact both cloud and traditional IT systems. The busy nature of infrastructure management, especially in scaling applications and services, can bring several challenges to organizations when adequately resourcing their departments. To address the concern, organizations need to accurately find possible areas of security concerns and streamline policies and controls according to them.

So, what cloud security challenges are we talking about?

  • Lack of visibility

In the cloud, it is easy to lose track of how an organization’s data is accessed and by whom. The issue occurs because many cloud services get accessed through third parties and lie outside the perimeter of corporate networks. And hence, cloud customers often cannot accurately identify and quantify their cloud assets or picture their cloud environments.

  • Multitenancy

Multitenancy of the cloud is also a critical issue that organizations face. The public cloud environments incorporate multiple cloud infrastructures under the same roof. The scenario lets an organization’s hosted services go compromised (collateral damage) by malicious hackers while targeting other businesses.

  • Access management

Organizations might successfully handle and control access points across on-premises systems. But in cloud environments, it becomes hard to administer the same level of restrictions as in on-premises systems. And if your organization can’t deploy the BYOD (bring-your-own-device) policies, it can trigger unfiltered access to your cloud services from any device.

  • Compliance

Regulatory compliance is another challenge or concern that sticks with hybrid or public cloud deployments. The accountability of data privacy is on the concerned organization’s shoulders. The heavy reliance on third-party solutions to manage this situation can drive numerous compliance issues for businesses.

  • Misconfigurations

What to tell more – misconfiguration of assets continues to be the prime cause for breaches in the cloud. In fact, it is one major issue in cloud computing environments. Lack of appropriate privacy settings and compromise of default administrative passwords are some of the misconfiguration issues.

Now let’s see what a robust cloud security framework tells.

  • Identity & Access Management

Identity| Authentication| Authorization| User Management

Identity & Access Management ensures that the right people and job roles in an organization have the required level of access to the right resources (Hardware, Software and Services).

  • Data Security

Data Classification| Data Control| Data Encryption| Data Availability| Data Life Cycle Management

Cloud Data Security marks the combination of policies, procedures and technology solutions organizations should implement to protect cloud-based applications and systems. It ranges from data classification, control, and encryption techniques to complete data life cycle management.

  • Hardware & Software Security

Physical Protection| Server Hardening| Security Patches

Hardware & Software Security in the cloud include actions like plugging the physical security, enabling biometric access techniques, running frequent scans, performing audits, applying patches & server hardening.

  • Network Security

Firewall| VPN| Internet Gateway| Security Group| Public & Private Subnets| Bastion Hosts| Internet Communication

Cloud Network Security is the ground layer of cloud security and is vital to protecting the data, applications, and IT resources within business cloud environments. It should have well-defined rules and configurations, firewall, and optimized security group specifications to confirm the safe accessibility of the applications in the cloud.

  • Disaster Recovery

Failover Mechanism| Minimal Service Interruption| Replication Mechanism| Data Loss Prevention Strategy| Backup & Restore Strategy

Cloud Disaster Recovery (cloud DR) is a process for restoring critical applications from the cloud in case of a crisis. The Key defining elements in the DR include the RTO (Recovery Time Objective) & RPO (Recovery Point Objective). Based on the agreed parameters, organizations should choose their required CDR strategies.

  • Governance & Compliance

Physical Data Location| Service Level Agreement| Regulatory Compliance| Security Audit| Security Assessments

While coming to the regulatory division, ISO/IEC 27001 and NIST 800–53 mark some of the globally accepted standard controls opted by organizations for managing information security and enabling seamless business operations. Besides these, organizations should conduct frequent security audits and adhere to their assessment requirements.

  • Monitoring & Logging

Traffic Monitoring| Threat Monitoring| Logging & Analytics| Incident Response| Mitigation Strategy

The specific part of the framework involves management of vulnerabilities & attacks, traffic monitoring, log management, analysis and incident response and remediation strategies. Cloud monitoring and logging are essential as it provides the keen observability needed to monitor business cloud infrastructure and applications.

  • Others

Application Security| Service Security Management| Third-party Security Management

There are also areas, including Services Security Management for microservices/API-based architecture, Third-party Security Management, and Application security that fulfil a robust cloud security framework requirement. Again, following secure development practice is essential at every stage of software development.

Final Thoughts

One thing uniting healthcare, banking, government, and any other industry is the critical need for information security beyond transformations. After steering through the cloud security challenges and the defined framework, it would be evident what the cloud brings to the big picture and what security options you harbour. However, there are limits to external help, and at a certain point, organizations should take control of their security practices in the cloud. Here is where pairing with a cloud security service provider creates the worth. ValueMentor is a trusted business choice for cloud security, offering multiple assessment services to industries, be it healthcare, banking, or government.
