What are the most common cloud security myths and misconceptions?

Perfect Security is imaginary, but it is a common misconception that cloud is inherently less secure than on-premises setup. A well reputed CSP can provide a very secure platform due to the following. 1. Clearly defined Security responsibility – "Security in the Cloud" and "Security of the Cloud" 2. Dedicated team of Security Professionals & Security research team 3. support of Multiple Native Security tools 4. Support for diverse Marketplace tools. 5. Advanced Security Threat Intelligence 6. Compliance to Multiple Regulations/standard 7. Support to Data Encryption and Security Protocols 8. Best Identity and Access Management Support 9. Continuous Audit and Monitoring 10. Native Redundancy built to support Business Continuity

Think of building in Cloud like building a house. Say that you go to Home Depot and ask a representative to build you a house. They may say, look around! We have all the resources e.g., concrete, lumber, nails, paint, and anything else you might need. Depending on your skill level, you may not be able to purchase all the supplies necessary, and construct a home on your own. Maybe, if you tried, there may be foundational issues like roof leaks or insecure door + lock installation. This is like building on the public cloud. All the components are there. The manner in which you plan, build, and maintain those components, is outside the purview of the public cloud provider.

Generalities like more or less secure are inaccurate when describing on premise or cloud operations. The only thing that matters is the ability of the organization to identify and execute the right controls for them. Look in the mirror, that person staring back, and their teammates, are the only ones who can create a safe space for business operations.

Debunk, Clarify, Secure! ☁️🚫 I'd debunk myths by clarifying that cloud security is robust when adequately managed. Providers share responsibility, but customers must secure their data, reflecting shared models in "Cloud Security and Privacy" by Tim Mather. Cloud solutions vary greatly, demanding tailored approaches. While often cost-effective, cloud economics require careful analysis compared to on-premises solutions. Migration necessitates strategic planning, and the cloud's dynamic nature demands continuous monitoring and adaptation, ensuring security evolves with emerging threats and technologies.

• Cloud Breaches are the Result of sophisticated APT Attacks: Not all breaches are sophisticated cyberattacks. Often, simple misconfigurations, weak passwords, or unpatched vulnerabilities lead to security incidents. Organizations should focus on basic security hygiene and best practices. • Security monitoring is easier on the cloud: Cloud environments can be complex, especially when dealing with multiple services, regions, and accounts. Achieving comprehensive visibility requires proper monitoring tools, logging, and continuous assessment of security posture.

Cloud service follows the shared responsibility model, this means the responsibility of cloud service provider and customer is clearly defined. Based on Service Model the responsibility is segregated between the customer and the CSP. In General, among SaaS, PaaS and IaaS service models 1. Storage – In all service models like SaaS, PaaS and IaaS the storge is the responsibility of CSP. 2. Services - In all service models like SaaS, PaaS and IaaS the service is the responsibility of CSP. 3. Networking, Operating System, Database, Virtualization– Other than IaaS the Networking, OS, DB and Virtualization are the responsibilities of CSP 4. Application and Middle ware – Only in SaaS model application and middleware are responsibility of CSP.

The myth that the cloud provider is solely responsible for all aspects of security is incorrect. It is coming from properly not understanding shared responsibility model, where the provider handles infrastructure security, while the customer is accountable for securing their data and applications. Organizations must understand their role in securing their information and work collaboratively with the cloud provider to maintain a secure & compliant cloud environment.

Cloud providers responsibility is to provide the up to date tools and technologies to ensure the security. However, customers responsibility is to build their security posture with the given standards and guidelines. Even though it’s shared responsibility, I would say customer should have better understanding to build robust security standards to their application to adhere to secure platform.

The myth that "The Cloud Provider is Responsible for Everything" is a significant misunderstanding of cloud security. In IaaS, the provider secures the infrastructure, but the user must protect their data, applications, and operating systems. In PaaS, the provider also secures the platform, including the operating system and runtime, yet the user is responsible for the applications and data on that platform. SaaS shifts more responsibility to the provider, covering infrastructure, platform, and software, but users still manage their data and user access. Believing the provider handles all security aspects is not just inaccurate, it's a risky oversight in safeguarding your cloud-based assets.

This is the most common I've ever came across. There is a false sense of belief that clouds are secure by default. Once you deploy something on cloud you don't have to care about its security, its all on the cloud provider, and since cloud provider is spending millions of dollars on their infrastructure so we are completely secure on cloud. NO! There's a shared responsibility model on every cloud provider, you're responsible for security of your app/infra in more areas than you actually think. Pushing a damn vulnerable app to cloud won't make it secure neither does cloud can help in protecting an years old non-patched system. Cloud is no magic.

Cloud Service Models can be many like SaaS, PaaS, IaaS. These three are predominant models and can come in different flavours. There is no one model for all, and organization can choose the right model after due risk assessment and considering following 10 factors. 1. Agility, Flexibility, Scalability and Reliability requirements 2. Performance Vs Availability or Both 3. Collaboration and tie-ups with partners 4. Data Governance 5. Data Security 6. Data Privacy 7. Technology and Business Roadmap 8. Service Level Agreements, Subcontracting 9. Cost, Budget and Commercials 10. Compliance requirements, Locking Period, Exit Criteria and CSP reputation.

In my experience, different organizations have vastly different security needs depending on their industry, regulatory environment, and operational model. For instance, while working with a healthcare organization, it became clear that a public cloud solution didn't provide the necessary controls for managing sensitive patient data. Instead, we opted for a hybrid cloud model, combining private cloud resources for critical data with public cloud for less sensitive workloads. This approach allowed us to tailor the security controls to meet specific compliance requirements, demonstrating that cloud solutions must be customized to fit the unique needs of each organization.

Even with public cloud there are significant differences between providers, and varying cost and quality for their security service offerings. Virtually everybody is multicloud these days (by choice or circumstance) which makes it important to consider both tooling that works across providers, and prepare your workforce for the differences. The CSPs have varying number of secure defaults (or not) but using org level controls to implement guardrails is extremely powerful (and cost effective) to prevent common cloud musconfigurations and implement audit logging that cannot be removed by either threat actors or your cloud admins.

Every organization is in a different state of Cloud Adoption, some simply consume a few SaaS solutions and others deeper into the cloud value proposition. Each type of cloud consumption (SaaS, PaaS, IaaS), and even offerings within, have their own unique attack surfaces and need to be considered in a way that allows adoption and does not stifle agility or business growth. One misconception I see very often is the assumption that traditional on-prem security tools have the coverage for whatever cloud applications may exist. As a very high level, initial view, for IaaS (in most cases) you can use your traditional tools, for PaaS you should investigate CNAPP (ideally with CWPP), for SaaS - CSAB, and in any case you should have a CSPM.

I agree with most of what has been stated, however the adoption of SaaS has blown up and CASB is no longer sufficient for securing SaaS. In many cases users access enterprise SaaS directly through SSO/MFA. SSPM (SaaS Security Posture Management) is the new and improved approach to proactively ensuring the risks of SaaS are managed.

A generalized statement about the cloud cost as compared to On- Premises setup can not be made. While plain vanilla model may be cheaper, but the cost increases significantly if there is security and compliance requirement along with visibility requirement is added to the service model chosen, as the cost of compliance many times can be very high and which added together can make Cloud more expensive. Following are the factor to decide the spend on the cloud: 1. Cloud Service Model 2. Service Usage 3. Sizing requirement 4. Data Governance cost 5. Data Security Cost 6. Data Privacy Cost 7. Egress Cost 8. Data Transfer and Connectivity cost 9. Market Place and Native tools selection 10. Infrastructure and Licensing cost

The cloud has many advantages including scalability, IAM, mobility, and security. For the most part, the company can save money over time if they are in the process of a refresh. There are significant advantages in management, patching, data center infrastructure, networking, and SLA. These features come at a cost. Ultimately you are outsourcing the management of the objects you are sharing, which can cause indirect savings. Things like user CALs, license management, development, data center employees, network load, bandwidth limitations, firewall hardware, physical and virtual server patch management, and more can be handled by the cloud provider. This frees up your IT staff to do more meaningful transformations without having to hire.

The cloud mainly provides scaleability and elasticity and with those speed. The advantage is on the speed side, so that infrastructure can be deployed quicker and business relevant products can be developed quicker. This has a positive impact on revenue but does not reduce cost. There are cases where scalability can reduce cost e.g. if you only pay per use and don't commit on usage you can also scale down. If you have less users, you pay less. With on-prem you would need to "buy" infrastructure if it is used or not.

The cloud can be cheaper or more expensive than on premise. However, this should not be the main reason why an organization uses cloud services. The main advantage of the cloud is agility and the capabilities, if used well, to move faster. In some cases, this agility come at an increase costs to the business, but this cost can be offset if the business is able to deliver new capabilities faster to market.

While cloud services reduce upfront costs and offer scalability, ongoing expenses can be very immoderate. Many organizations don't monitor their resource usage effectively, over-provision VMs, oversize compute resources, leave unused services running, leading to wasted costs. Technical factors like data transfer fees, underutilized reserved instances, and using the wrong storage options also lead to expensive bills. There is also a cost related to ensuring security and compliance in the cloud, often requiring investment and specialized tools like CASB or CWPP, leading to increasing costs.

Whereas on-prem security is very network centric, cloud security is very identity centric. Migrating to the cloud comes with plenty of challenges. The big benefit of cloud is elasticity and scaleability. If a company lift-and-shifts their on-prem servers to the cloud, they won't be elastic or scaleable. With that migration step you do not benefit much from the cloud. It is always better to rebuild in a cloud native way. The workload as well as the security.

In has been my experience that most organizations in a rush to move to the cloud lift their on premise applications, instead of refractor them using cloud native software development practices. This practice leads to disappointment as they are unable to maximize the full benefits of using the cloud. An application that was costly to maintain on premise, could be as or more difficult to do so in a cloud environment when it was not refactored using cloud native software engineering practices.

The reality is, though, that the move to cloud is based on business incentives, making refactoring and a culture change difficult to do before a cloud migration. Therefore a lift-and-shift to get into the cloud is generally stage 1, that should be followed up by refactoring to increasingly cloud-native approaches in a stage 2.

To focus your interpretation of the following, let’s agree the only difference between cloud and your present location is who holds the liability. Cloud just means a bigger data center someone else manages. The hardest step towards cloud migration is the first one. Many companies have lost key knowledge about how their services operate; getting them to operate in a new context (the cloud) can be painful. Complicating migration by requiring refactoring should not be your first choice. Think of migration as a discovery process moving your monolithic service into the light of infrastructure as code (IaC). Once you have services defined as IaC, there are many innovative approaches to modernization.

Organizations must adopt a structured and systematic approach, taking into account various factors to ensure a smooth and secure transition. By recognizing the challenges and implementing thorough planning, organizations can reap the benefits of cloud computing while safeguarding their data and applications.

The cloud security landscape is in constant flux, with new threats, vulnerabilities, and regulatory changes emerging regularly. Adopting a proactive and agile approach to cloud security is essential. Organizations must utilize advanced tools and techniques for timely detection, prevention, response, and recovery from cloud security incidents to maintain a robust security posture. In reality, the cloud is a dynamic and evolving environment. This necessitates that organizations continuously monitor, update, and enhance their cloud security measures

Therefore, don't consider a cloud migration a big project or event that once "done" will be "over" and return to a previous "normal". Cloud transformation is a continuing process, and adopting an agile, cloud-native mindset and practice is therefore critical in order to keep up with constant change.

In essence, the myth of the cloud being static and stable is debunked by the reality of its dynamic and ever-changing nature. Organizations must adopt a proactive approach to cloud security, recognizing that continuous monitoring, regular updates, and improvements are imperative. This perspective ensures that organizations remain resilient in the face of evolving threats, comply with changing regulations, harness new technologies, and meet the dynamic expectations of their customers in the fast-paced and dynamic landscape of cloud computing.

Cloud is definitely not static. As a cloud professional, I renew my Azure certifications every year. To do that, I study the new materials that highlight the delta since last year. It's amazing how fast the cloud evolves; new services and features are added all the time. From AI to data analytics, to cloud security, to platform services, to infrastructure options ranging from networking, storage, and computing. Thanks to the competition amongst the three hyperscalers, they keep improving and updating their cloud.

An example of the cloud constantly changing and requiring hands on management are the plethora of new features being added to all cloud platforms. (LLMs are the latest and greatest new feature coming to many clouds) These new features may not suit the needs of your organization and can also cause numerous security concerns. Default or poor configuration of cloud services should be treated as a vulnerability as this can increase your attack surface. From my experience, I agree with what was said above, you need to have a proactive team that is well researched and equipped to meet any challenge or new features added to your cloud platforms to know and manage your risk.

One prevalent misconception is the assumption that all endpoint security controls operate uniformly across all cloud platforms. The reality is that security controls can vary significantly between different cloud providers. Native security tools such as AWS GuardDuty or Azure Security Center are usually customized for their specific platforms and often offer better integration and performance compared to third-party alternatives. It is crucial for organizations to understand the unique security offerings of their selected cloud platform and choose tools and services that align with their specific requirements and infrastructure.

Cloud security myths & misconceptions often stem from a lack of understanding about the shared responsibility model. The shared responsibility model establishes a collaborative effort between the cloud service provider & the customer. Cloud providers manage the security OF the cloud, customers are responsible for security IN the cloud. This means securing their data, configuring access controls, & implementing best practices within their cloud environment. The responsibility for securing applications & data shifts to the customer. Adherence to regulatory standards also remains a shared responsibility. Understanding the shared responsibility model empowers organizations to make informed decisions, & implement appropriate security measures.

When considering cloud security, it's also important to think about the human element. One real-world example from my career involved conducting a security awareness training for a company transitioning to the cloud. Despite having robust technical controls in place, the organization was still vulnerable due to a lack of employee understanding about cloud security practices. By integrating cloud-specific scenarios into our training, such as recognizing phishing attempts that target cloud credentials, we significantly reduced the risk of human error compromising the cloud environment. This experience underscores the importance of aligning technical security measures with employee education to create a comprehensive cloud security strategy.

Some organizations mistakenly believe that moving to the cloud means they no longer need to worry about security. However, cloud migration introduces new security challenges and considerations, such as data privacy, compliance requirements, and identity management. Security measures must be implemented and maintained throughout the cloud migration process and beyond to mitigate risks effectively.

A clear understanding of data sovereignty laws and regulations is also another key element in the design of an overall security architecture in the cloud. All major Cloud Service Providers (CSPs) are extending their presence to different geographies in an effort to help their customers comply with such regulations.
