What Is IT Infrastructure Security?
If you are reading this blog, we would like to assume that you are either an aspiring cybersecurity professional or a business owner looking for ways to improve their network security. A business IT infrastructure includes networks, software, hardware, equipment, and other facilities that make up an IT network. These networks are applied to establish, monitor, test, manage, deliver, and support IT services.
So, IT infrastructure security describes the process of safeguarding the core networking infrastructure, and it is typically applied to enterprise IT environments. You can improve IT infrastructure security by installing protective solutions to block unauthorized access, theft, deletion, and data modification.

Hyper-Converged Infrastructure
Article | September 14, 2023
DApps (sometimes called Dapps) are from the blockchain universe and so, logically, the apps part stands for application (obviously) and the D part stands for decentralised (only obvious once you know that we’re talking distributed immutable language here). According to the guides section at blockgeeks, DApps are open source in terms of code base, incentivised (in terms of who validates it) and essentially decentralised so that all records of the application’s operation must be stored on a public and decentralised blockchain to avoid pitfalls of centralisation. So then, Cartesi is a DApp infrastructure that runs an operating system (OS) on top of blockchains. The company has now launched a more complete ‘platform-level’ offering, which is described as a layer-2 solution

The rollout of 5G networks coupled with edge compute introduces new security concerns for both the network and the enterprise. Security at the edge presents a unique set of security challenges that differ from those faced by traditional data centers. Today new concerns emerge from the combination of distributed architectures and a disaggregated network, creating new challenges for service providers.
Many mission critical applications enabled by 5G connectivity, such as smart factories, are better off hosted at the edge because it's more economical and delivers better Quality of Service (QoS). However, applications must also be secured; communication service providers need to ensure that applications operate in an environment that is both safe and provides isolation. This means that secure designs and protocols are in place to pre-empt threats, avoid incidents and minimize response time when incidents do occur.
As enterprises adopt private 5G networks to drive their Industry 4.0 strategies, these new enterprise 5G trends demand a new approach to security. Companies must find ways to reduce their exposure to cyberattacks that could potentially disrupt mission critical services, compromise industrial assets and threaten the safety of their workforce. Cybersecurity readiness is essential to ensure private network investments are not devalued.
The 5G network architecture, particularly at the edge, introduces new levels of service decomposition now evolving beyond the virtual machine and into the space of orchestrated containers. Such disaggregation requires the operation of a layered technology stack, from the physical infrastructure to resource abstraction, container enablement and orchestration, all of which present attack surfaces which require addressing from a security perspective. So how can CSPs protect their network and services from complex and rapidly growing threats?
Addressing vulnerability points of the network layer by layer
As networks grow and the number of connected nodes at the edge multiply, so do the vulnerability points. The distributed nature of the 5G edge increases vulnerability threats, just by having network infrastructure scattered across tens of thousands of sites. The arrival of the Internet of Things (IoT) further complicates the picture: with a greater number of connected and mobile devices, potentially creating new network bridging connection points, questions around network security have become more relevant.
As the integrity of the physical site cannot be guaranteed in the same way as a supervised data center, additional security measures need to be taken to protect the infrastructure. Transport and application control layers also need to be secured, to enable forms of "isolation" preventing a breach from propagating to other layers and components. Each layer requires specific security measures to ensure overall network security: use of Trusted Platform Modules (TPM) chipsets on motherboards, UEFI Secure OS boot process, secure connections in the control plane and more. These measures all contribute to and are integral part of an end-to-end network security design and strategy.
Open RAN for a more secure solution
The latest developments in open RAN and the collaborative standards-setting process related to open interfaces and supply chain diversification are enhancing the security of 5G networks. This is happening for two reasons. First, traditional networks are built using vendor proprietary technology – a limited number of vendors dominate the telco equipment market and create vendor lock-in for service providers that forces them to also rely on vendors' proprietary security solutions. This in turn prevents the adoption of "best-of-breed" solutions and slows innovation and speed of response, potentially amplifying the impact of a security breach.
Second, open RAN standardization initiatives employ a set of open-source standards-based components. This has a positive effect on security as the design embedded in components is openly visible and understood; vendors can then contribute to such open-source projects where tighter security requirements need to be addressed.
Aside from the inherent security of the open-source components, open RAN defines a number of open interfaces which can be individually assessed in their security aspects. The openness intrinsically present in open RAN means that service components can be seamlessly upgraded or swapped to facilitate the introduction of more stringent security characteristics, or they can simultaneously swiftly address identified vulnerabilities.
Securing network components with AI
Monitoring the status of myriad network components, particularly spotting a security attack taking place among a multitude of cooperating application functions, requires resources that transcend the capabilities of a finite team of human operators. This is where advances in AI technology can help to augment the abilities of operations teams. AI massively scales the ability to monitor any number of KPIs, learn their characteristic behavior and identify anomalies – this makes it the ideal companion in the secure operation of the 5G edge. The self-learning aspect of AI supports not just the identification of known incident patterns but also the ability to learn about new, unknown and unanticipated threats.
Security by design
Security needs to be integral to the design of the network architecture and its services. The adoption of open standards caters to the definition of security best practices in both the design and operation of the new 5G network edge. The analytics capabilities embedded in edge hyperconverged infrastructure components provide the platform on which to build an effective monitoring and troubleshooting toolkit, ensuring the secure operation of the intelligent edge.

1. Introduction
Ensuring Infrastructure as a Service (IaaS) compliance in security is crucial for organizations to meet regulatory requirements and avoid potential legal and financial consequences. However, several challenges must be addressed before and after migration to the cloud. This article provides an overview of the regulatory requirements in cloud computing, explores the challenges faced in ensuring compliance in IaaS, a cloud implementation service and provides strategies for addressing these challenges to ensure a successful cloud migration.
2. 3 Essential Regulatory Requirements
When adopting cloud infrastructure as a service, organizations must comply with regulatory requirements before, during, and after migration to the cloud. This ensures avoiding the challenges, firms may face later and suggest solutions if they do so.
2.1 Before migration:
Organizations must identify the relevant regulations that apply to their industry and geographic location. This includes: Data Protection Laws, Industry-Specific Regulations, and International Laws.
2.2. During migration:
Organizations must ensure that they meet regulatory requirements while transferring data and applications to the cloud. This involves: Ensuring proper access management, data encryption, and data residency requirements.
2.3. After migration:
Organizations must continue to meet regulatory requirements through ongoing monitoring and reporting. This includes: Regularly reviewing and updating security measures, ensuring proper data protection, and complying with audit and reporting requirements.
3. Challenges in Ensuring Compliance in Infrastructureas a Service in Cloud Computing
3.1. Shared Responsibility Model
The lack of control over the infrastructure in IaaS cloud computing is caused by the shared responsibility model of IaaS, where the cloud service provider is responsible for the IaaS security while the customer is responsible for securing the data and applications they store and run in the cloud. According to a survey, 22.8% of respondents cited the lack of control over infrastructure as a top concern for cloud security. (Source: Cloud Security Alliance)
3.2. Data Breach
Data breaches have serious consequences for businesses, including legal and financial penalties, damage to their reputation, and the loss of customer trust. The location of data and the regulations governing its storage and processing create challenges for businesses operating in multiple jurisdictions. The global average total cost of a data breach increased by USD 0.11 million to USD 4.35 million in 2022, the highest it's been in the history of this report. The increase from USD 4.24 million in the 2021 report to USD 4.35 million in the 2022 report represents a 2.6% increase. (Source: IBM)
3.3. Access Mismanagement
Insider threats, where authorized users abuse their access privileges, can be a significant challenge for access management in IaaS. This includes the intentional or accidental misuse of credentials or non-protected infrastructure and the theft or loss of devices containing sensitive data. The 2020 data breach investigations report found that over 80% of data breaches were caused by compromised credentials or human error, highlighting the importance of effective access management.

3.4. Audit and Monitoring Challenges
Large volumes of alerts overwhelm security teams, leading to fatigue and missed alerts, which result in non-compliance or security incidents going unnoticed. Limited resources may also make it challenging to effectively monitor and audit infrastructure as a service cloud environment, including the implementation and maintenance of monitoring tools.
4. Strategies for Addressing Compliance Challenges in IaaS
4.1. Risk Management and Assessment
Risk Assessment and Management includes conducting a risk assessment, including assessing risks related to data security, access controls, and regulatory compliance. It also involves implementing risk mitigation measures to address identified risks, like additional security measures or access controls such as encryption or multi-factor authentication.
4.2. Encryption and Collaboration with Cloud Service Providers
Encryption can be implemented at the application, database, or file system level, depending on the specific needs of the business. In addition, businesses should establish clear service level agreements with their cloud service provider related to data protection. This includes requirements for data security, access controls, and backup and recovery processes.
4.3. Contractual Agreements
The agreement should also establish audit and compliance requirements, including regular assessments of access management controls and policies. Using contractual agreements, organizations help ensure that they are clearly defined and that the cloud service provider is held accountable for implementing effective access management controls and policies.
4.4. Compliance Monitoring and Reporting
Monitoring and Reporting involves setting up automated monitoring and reporting mechanisms that track compliance with relevant regulations and standards and generate reports. They should also leverage technologies such as intrusion detection and prevention systems, security information and event management (SIEM) tools, and log analysis tools to collect, analyze, and report on security events in real time.
5. Conclusion
In accordance with the increasing prevalence of data breaches and the growing complexity of regulatory requirements, maintaining a secure and compliant cloud environment will be crucial for businesses to build trust with customers and avoid legal and financial risks. Addressing these requirements, the cloud helps companies maintain data privacy, avoid legal risks, and build customer trust. Organizations create a secure and compliant cloud environment that meets their needs by overcoming challenges and implementing best practices, working closely with cloud service providers.
