Unlocking Financial Agility with Cloud Solutions

Cloud computing is a term that has gained popularity in recent years, especially in the financial sector. But what is cloud computing and why is it important for the emerging financial environment? In this article, we will explore the definition, benefits, risks, and types of cloud computing, and how it can help financial institutions achieve their goals in a dynamic and competitive market.

What is Cloud Computing?

According to the National Institute of Standard and Technology (NIST), cloud computing is a model that enables pervasive, efficient, and on-demand connectivity to a shared collection of adaptable computing assets (e.g., channels, servers, retrieval, implementations, and systems), which can be based on growth and economic development, and is issued with little managerial or managed service communication. In simpler terms, cloud computing allows users to access computing resources over the internet without having to own or manage them.

Cloud computing has some key characteristics, such as:

  • Self-service on demand: Users can request and obtain computing resources as needed without human intervention.
  • Broad network connectivity: Users can access computing resources from anywhere and on any device through the internet or a private network.
  • Virtualized resources: Computing resources are pooled and shared among multiple users, and can be dynamically allocated and released according to demand.
  • Rapid elasticity: Computing resources can be scaled up or down quickly and easily to meet changing needs.
  • Metered service: Users pay only for the amount of computing resources they use, based on a predefined measure.

Why is Cloud Computing Important For The Emerging Financial Environment?

Cloud computing offers several benefits for the financial sector, such as:

  • Lower IT costs: Cloud computing reduces the need for investing in and maintaining expensive hardware and software, as well as hiring IT staff. Users can save money by paying only for what they use and avoiding upfront capital expenditures.
  • Flexibility: Cloud computing enables users to adapt to changing business needs and customer expectations by providing access to a variety of computing resources and services. Users can also scale their resources up or down as needed without affecting performance or availability.
  • Business continuity: Cloud computing enhances the reliability and resilience of IT systems by providing backup and recovery options, redundancy, and fault tolerance. Users can also access their data and applications from anywhere in case of a disaster or disruption.
  • Accessibility: Cloud computing allows users to access their data and applications from anywhere and on any device, as long as they have an internet connection. This improves customer service, collaboration, and productivity.
  • Efficiency and security: Cloud computing improves the efficiency and security of IT systems by providing automated updates, patches, and maintenance, as well as encryption, authentication, and monitoring.

Users can also benefit from the expertise and best practices of cloud service providers.

Cloud Computing Risks

However, cloud computing also entails some risks that need to be considered before adoption, such as:

  • Data privacy and security: Cloud computing involves transferring sensitive data to thirdparty providers who may have different policies and standards for data protection. Users need to ensure that their data is encrypted, anonymized, or masked when stored or transmitted over the cloud, and that they comply with relevant regulations and laws.
  • Vendor lockin: Cloud computing may create dependency on a single or a few providers who may have different service levels, pricing models, or technical capabilities. Users need to ensure that they have the flexibility to switch providers or migrate their data and applications if needed.
  • Performance and availability: Cloud computing relies on the internet or a private network for accessing computing resources, which may be affected by bandwidth limitations, latency issues, or network failures. Users need to ensure that they have adequate connectivity and backup plans in case of outages or disruptions.
  • Compliance and governance: Cloud computing involves delegating some control and responsibility over IT systems to external providers who may have different policies and standards for compliance and governance. Users need to ensure that they have visibility and accountability over their cloud operations, and that they adhere to relevant regulations and laws.

Types of Cloud Computing?

There are different types of cloud computing based on the deployment model, service model, or functionality. Some of the common types are:

Deployment Model

The deployment model refers to how the cloud infrastructure is provisioned for use by users. There are four main types of deployment models:

  • Private cloud: The cloud infrastructure is exclusively used by a single organization or a group of organizations that share common goals or interests. The infrastructure may be owned, managed, or operated by the organization itself or by a thirdparty provider. The infrastructure may be located on premise or off-premise.
  • Community cloud: The cloud infrastructure is shared by several organizations that have common goals or interests. The infrastructure may be owned, managed, or operated by one or more of the organizations or by a thirdparty provider. The infrastructure may be located onpremise or offpremise.
  • Public cloud: The cloud infrastructure open to a wider audience for utilization. This infrastructure could be owned, controlled, and operated by various entities such as organizations, educational institutions, public bodies, or a hybrid combination of these. Essentially, it provides accessibility to the general public and is hosted on the facilities of the service provider.
  • Hybrid cloud: In the realm of hybrid cloud architecture, a composition of several separate cloud environments—private, communal, or public—exists. Each of these environments retains its distinct components. What makes hybrid cloud unique is its interconnection through standardized or patented technology. This connectivity facilitates the mobility of both information and applications across these diverse cloud environments.

Cloud service models

There are different types of cloud service models that provide different levels of control, responsibility, and functionality to the users. In this article, Three main types of cloud service models, as defined by the National Institute of Standards and Technology (NIST), and give some examples of each.

  • Infrastructure as a Service (IaaS): This is the most basic type of cloud service model, where the user can provision and manage the physical and virtual resources of the cloud infrastructure, such as servers, storage, network, and operating systems. The user can install and run any software applications on these resources, without having to worry about the maintenance and administration of the underlying hardware and software platforms. The user only pays for the resources that they use, and can scale them up or down as needed. Some examples of IaaS providers are Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and IBM Cloud.
  • Platform as a Service (PaaS): This is a type of cloud service model where the user can develop and deploy their own applications on a cloud platform, using various tools, frameworks, and languages provided by the cloud provider. The user does not have to manage the underlying infrastructure, such as servers, storage, network, or operating systems, but only has control over the configuration and settings of their applications and development environments. The user only pays for the platform services that they use, and can benefit from the scalability, reliability, and security of the cloud platform. Some examples of PaaS providers are Heroku, Salesforce, Google App Engine, and AWS Elastic Beanstalk.
  • Software as a Service (SaaS): This is a type of cloud service model where the user can access and use the software applications that are hosted and managed by the cloud provider. The user does not have to install or maintain any software on their own devices, but only needs a web browser or a mobile app to access the cloud applications. The user does not have any control over the underlying infrastructure or software platforms, but may have some customization options for the software features and functions. The user pays for the software subscription or usage fee, and can enjoy the convenience, performance, and security of the cloud applications. Some examples of SaaS providers are Gmail, Microsoft Office 365, Dropbox, Netflix, and Zoom.
  • Cloud computing is a rapidly growing technology that offers many benefits for businesses of all sizes and industries. However, it also comes with some challenges and risks that need to be addressed and mitigated. In this article, we will discuss some of the common cloud security risks, how to ensure data security in cloud computing, and the advantages of incorporating cloud computing into professional workflows.

Cloud Security Risks

Cloud security risks are the potential threats and vulnerabilities that can compromise the confidentiality, integrity, and availability of cloud services and data. Some of the common cloud security risks are:

Cloud Misconfigurations:

One of the most prevalent cloud security risks is cloud misconfiguration. This occurs when cloud resources are not properly configured or secured, leading to unauthorized access, data leakage, or service disruption. For example, a cloud storage bucket may be left open to the public, exposing sensitive data to anyone who can find it. Or, a cloud user may have elevated privileges that allow them to perform actions that they should not be able to do, such as deleting or modifying data.To prevent cloud misconfigurations, organizations need to implement best practices for cloud security, such as following the principle of least privilege, enforcing role-based access control, applying encryption and authentication, and using tools that can automatically detect and remediate configuration errors.

Third-Party Threats:

Another cloud security risk is third-party threats. This refers to the risk posed by third-party software-as- a-service (SaaS) providers that organizations use to enhance their cloud capabilities. For example, a SaaS provider may offer a cloud-based email service, a CRM system, or a collaboration platform. While these services can provide many benefits, they also introduce new attack vectors for hackers who may target the SaaS provider or its customers.

To reduce third-party threats, organizations need to conduct effective third-party risk assessment processes, such as verifying the security posture and reputation of the SaaS provider, reviewing the terms and conditions of the service agreement, and monitoring the performance and availability of the service.

Supply Chain Attacks:

A related cloud security risk is supply chain attacks. This is when hackers exploit weaknesses in the distribution chain of software or hardware components that are used by cloud providers or customers. For example, a hacker may compromise a software update that is delivered to a cloud server, or a hardware device that is connected to a cloud network. By doing so, they can gain access to the cloud environment and launch further attacks.

To prevent supply chain attacks, security professionals need to proactively identify and fix vulnerabilities in their software and hardware components, as well as in their suppliers' components. They also need to implement security measures such as code signing, integrity checking, and patch management.

 

Zero-Day Vulnerabilities:

  A zero-day vulnerability is an unsecured flaw in a technology that is unknown to the vendor or the public until it is       exploited by hackers. Zero-day vulnerabilities can affect any type of technology, including cloud platforms and services.   For example, a zero-day vulnerability may exist in a cloud operating system, a cloud application, or a cloud API. Hackers   can use these vulnerabilities to bypass security controls and execute malicious code on the cloud. To mitigate zero-day vulnerabilities, organizations need to swiftly discover and remediate them before they are exploited. They can do this by using tools that can scan and test their cloud systems for vulnerabilities, as well as by subscribing to security alerts and advisories from vendors and researchers.

Inadequate Due Diligence:

One of the most avoidable cloud security risks is inadequate due diligence. This is when organizations fail to conduct comprehensive vendor evaluations before choosing a cloud provider or service. For example, an organization may select a cloud provider based on price or convenience, without considering its security capabilities, policies, or track record. This may lead to severe breaches if the provider turns out to be unreliable, untrustworthy, or compromised.To avoid inadequate due diligence, organizations need to perform thorough vendor assessments before signing any contracts or agreements with cloud providers or services. They need to verify the provider's credentials, certifications, compliance status, references, and reviews. They also need to review the provider's security architecture, controls, processes, and incident response plans.

Non-Compliance:

This is when organizations fail to adhere to the regulatory and industry norms that govern their data and operations in the cloud. For example, an organization may store personal data in the cloud without obtaining consent from the data subjects or complying with data protection laws. Or, an organization may use a cloud service that does not meet the standards or requirements of its industry sector or domain. To ensure compliance in the cloud, organizations need to continuously monitor their SaaS providers' compliance status and performance. They also need to implement compliance controls and policies in their own cloud systems and processes. They need to be aware of the applicable laws and regulations in their jurisdiction and sector and follow them accordingly.

Data Security in Cloud Computing

Data security in cloud computing is the protection of data from unauthorized access, use, disclosure, modification, or destruction while it is stored, processed, or transmitted in the cloud. Data security in cloud computing can be achieved by implementing various cloud security controls, such as:

  • Use multistep authentication. This means that you need more than just a username and password to access your cloud account or service. You may also need a code sent to your phone, an email confirmation, a biometric scan, or a physical token. Multistep authentication adds an extra layer of security and prevents unauthorized access to your data.
  • Encrypt your data. Encryption is the process of transforming data into an unreadable format that can only be decrypted with a key. Encryption protects your data from being stolen or tampered with by hackers or malicious insiders. You can encrypt your data before uploading it to the cloud, or use a cloud service that offers encryption as a feature.
  • Update your software regularly. Software updates often contain patches and fixes for security vulnerabilities and bugs that could compromise your data. You should update your operating system, browser, antivirus, firewall, and any other software that you use to access the cloud. You should also enable automatic updates whenever possible.
  • Monitor your cloud infrastructure. You should keep track of who is accessing your cloud account or service, what they are doing, and where they are located. You can use tools like logs, alerts, dashboards, and reports to monitor your cloud activity and detect any suspicious or abnormal behavior. You should also review your cloud provider's security policies and procedures and make sure they meet your standards.
  • Plan for business continuity. Business continuity is the ability to resume normal operations after a disruption or disaster. You should have a plan for how to recover your data in case of a cloud outage, breach, or loss. You should consider factors like recovery time objective (RTO), which is the maximum amount of time you can afford to be without your data, and recovery point objective (RPO), which is the maximum amount of data you can afford to lose. You should also backup your data regularly and test your recovery plan periodically.
  • Control your cloud access. You should limit who can access your data in the cloud and what they can do with it. You can use a cloud access control list (ACL) to specify the permissions and privileges for each user or group. You can also use rolebased access control (RBAC) to assign roles and responsibilities based on job functions. You should also revoke access when it is no longer needed or when a user leaves the organization.

By following these best practices and tips, you can improve your data security in the cloud and protect your data from unauthorized access, theft, or loss.

Cloud Security Controls: Data at Rest and Data in Motion

Data security in the cloud involves protecting two types of data: data at rest and data in motion.

Data at rest is data that is stored and inactive in the cloud, such as files, databases, backups, archives, etc. Data at rest is vulnerable to unauthorized access, theft, or deletion by hackers or malicious insiders.

Data in motion is data that is actively transmitted over the internet or within the cloud network, such as emails, chats, video calls, web browsing, etc. Data in motion is vulnerable to interception, modification, or redirection by hackers or malicious actors.

To protect both types of data, you need to implement different types of cloud security controls:

  • Data at rest: To protect data at rest, you need to use encryption and access control. Encryption transforms data into an unreadable format that can only be decrypted with a key. Access control limits who can access data and what they can do with it.
  • Data in motion: To protect data in motion, you need to use encryption and secure protocols. Encryption protects data from being intercepted or modified by hackers or malicious actors. Secure protocols are rules and standards that govern how data is transmitted over the internet or within the cloud network.

Advantages of Incorporating Cloud Computing into Professional Workflows

Cloud computing is a technology that allows users to access and process data over the internet, rather than on their own devices or servers. This has many benefits for professionals who want to improve their workflows, productivity, and efficiency.
