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.
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:
Cloud computing offers several benefits for the financial sector, such as:
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:
There are different types of cloud computing based on the deployment model, service model, or functionality. Some of the common types are:
The deployment model refers to how the cloud infrastructure is provisioned for use by users. There are four main types of deployment 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.
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:
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.
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.
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.
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.
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.
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 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:
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.
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:
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. In this article, we will explore some of the advantages of incorporating cloud computing into your professional activities, especially in the areas of accounting, collaboration, automation, data storage, security, and scalability.
One of the most common applications of cloud computing is accounting software. Cloud-based accounting software enables you to manage your finances online, without having to install or update any software on your device. You can access your accounting data from anywhere, at any time, and on any device, as long as you have an internet connection. You can also share your data with your accountant, bookkeeper, or colleagues in real-time, and collaborate on financial reports and statements. Cloud-based accounting software also offers features such as automatic backups, encryption, tax compliance, invoicing, and integration with other cloud services.
Another advantage of cloud computing is that it facilitates collaboration and remote work. Cloud computing allows you to access and edit documents, spreadsheets, presentations, and other files online, and sync them across multiple devices. You can also use cloud-based tools such as video conferencing, chat, email, and project management to communicate and coordinate with your team members, clients, and partners. Cloud computing enables you to work from anywhere, as long as you have an internet connection. This can increase your flexibility, mobility, and productivity.
Cloud computing also helps you automate and integrate your workflows. Cloud computing allows you to use software as a service (SaaS), which means that you can access applications online without having to install or maintain them on your device. You can also use platform as a service (PaaS), which means that you can create and deploy your own applications online without having to manage the underlying infrastructure. You can also use infrastructure as a service (IaaS), which means that you can rent servers, storage, network, and other resources online without having to buy or maintain them. These services allow you to automate tasks such as data processing, backup, recovery, security, and scaling. They also allow you to integrate different cloud services and applications using APIs (application programming interfaces) or connectors.
Cloud computing also offers advantages in terms of data storage and backup. Cloud computing allows you to store your data online, rather than on your device or server. This can save you space, cost, and time. You can also access your data from anywhere, at any time, and on any device, as long as you have an internet connection. You can also backup your data online automatically or manually, and restore it in case of loss or damage. Cloud computing also provides redundancy and replication of your data across multiple locations and servers, which can enhance its availability and reliability.
