Hyper-Converged Infrastructure
Article | July 13, 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

Businesses are depending more and more on information technology to accomplish daily objectives. The viability and profitability of a firm are directly impacted by the necessity of putting the appropriate technological processes in place. The misunderstanding that "the Internet is down" is often associated with poor internet connectivity shows how crucial network maintenance is since troubleshooting should always begin and conclude with a network expert. In actuality, though, that employee will spend time out of their day to "repair the Internet," and the money spent on that time is the result of the company's failure to implement a dependable network monitoring system. The direct financial loss increases with network unreliability.
Because expanding wide area network (WAN) infrastructure and cloud networking have now become a significant component of today's enterprise computing, networks have grown much more virtualized and are no longer restricted to either physical location or hardware. While networks themselves are evolving, there is a growing need for IT network management. As organizations modernize their IT infrastructure, they should think about purchasing a network management system for several reasons.
Creating More Effective, Less Redundant Systems
Every network has to deal with data transfer through significant hubs and the flow of information. In order to avoid slowing down data transfer, not using up more IP addresses in a network scheme than necessary, and avoiding dead loops, networking engineers have had to carefully route networking equipment to end devices over the years. An effective IT management solution can analyze how your network is operating and provide immediate insights into the types of changes you need to make to cut down on redundancy and improve workflow. More productivity and less time spent troubleshooting delayed data transfers result from increased efficiency.
Increasing Firewall Defense
Given that more apps are being utilized for internal and external massive data transfers, every network must have adequate firewalls and access control setup. In addition to screen sharing and remote desktop services, more companies require team meeting software with live video conferencing choices. Programs with these features can be highly vulnerable to hackers and other vulnerabilities; thus, it's crucial that firewalls stop attackers from utilizing the software to access restricted sections of corporate networks. Your network management tools can set up your firewalls and guarantee that only secure network connections and programs are used in critical parts of your system.
The bottom line is that your company network will constantly require security and development, and your underlying network must be quick and dependable to satisfy demands for both workplace productivity and customer experience. Which IT network management system, nevertheless, is best for your company? Effectiveness doesn't require a lot of complexity, and if it works with well-known network providers, there's a good chance the cost will be justified. Rock-solid security will be the most crucial factor, but you should also search for a system that can operate on physical, cloud, and hybrid infrastructure.

1. Introduction
Infrastructure as a Service has become an increasingly popular way of deploying and managing applications, and containerization has emerged as a leading technology for packaging and deploying these applications. Containers are software packages that include all the necessary components to operate in any environment. While containers offer numerous benefits, such as portability, scalability, and speed, they also introduce new security challenges that must be addressed.
Implementing adequate IaaS container security requires a comprehensive approach encompassing multiple layers and techniques. This blog explores the critical components of IaaS container security. It provides an overview of the techniques and best practices for implementing security measures that ensure the confidentiality and integrity of containerized applications. By following these, organizations can leverage the benefits of IaaS and containerization while mitigating the security risks that come along.
2. IaaS Container Security Techniques
The increasing IAAS security risks and security issues associated with IAAS these days are leading to a massive data breach. Thus, IAAS security concerns are taken into consideration, and seven best techniques are drafted below.
2.1. Container Image Security:
Container images are the building blocks of containerized applications. Ensuring the security of these images is essential to prevent security threats. The following measures are used for container image security:
Using secure registries: The registry is the location where container images are stored and distributed. Usage of centrally managed registries on campus, the International Organization for Standardization (ISO) can scan them for security issues and system managers may simply assess package gaps, etc.
Signing images: Container images can be signed using digital signatures to ensure their authenticity. Signed images can be verified before being deployed to ensure they have not been tampered with.
Scanning images: Although standard AppSec tools such as Software Composition Analysis (SCA) can check container images for vulnerabilities in software packages and dependencies, extra dependencies can be introduced during the development process or even at runtime.
2.2. Host Security:
Host security is a collection of capabilities that provide a framework for implementing a variety of security solutions on hosts to prevent attacks. The underlying host infrastructure where containers are deployed must be secured. The following measures are used for host security:
Using secure operating systems: The host operating system must be safe and up-to-date with the latest high severity security patches within 7 days of release, and others, within 30 days to prevent vulnerabilities and security issues.
Applying security patches: Security patches must be applied to the host operating system and other software packages to fix vulnerabilities and prevent security threats.
Hardening the host environment: The host environment must be hardened by disabling unnecessary services, limiting access to the host, and applying security policies to prevent unauthorized access.
2.3. Network Security:
Network security involves securing the network traffic between containers and the outside world. The following measures are used for network security:
Using Microsegmentation and firewalls: Microsegmentation tools with next-gen firewalls provide container network security. Microsegmentation software leverages network virtualization to build extremely granular security zones in data centers and cloud applications to isolate and safeguard each workload.
Encryption: Encryption can protect network traffic and prevent eavesdropping and interception of data.
Access control measures: Access control measures can restrict access to containerized applications based on user roles and responsibilities.
2.4. Data Security:
Data stored in containers must be secured to ensure its confidentiality and integrity. The following measures are used for data security:
Using encryption: Data stored in containers can be encrypted, using Transport Layer Security protocol version 1.1. (TLS 1.1) or higher, to protect it from unauthorized access and prevent data leaks. All outbound traffic from private cloud should be encrypted at the transport layer.
Access control measures: Access control measures can restrict access to sensitive data in containers based on user roles and responsibilities.
Not storing sensitive data in clear text: Sensitive data must not be stored in clear text within containers to prevent unauthorized access and data breaches. Backup app data, atleast weekly.
2.5. Identity and Access Management (IAM):
IAM involves managing access to the container infrastructure and resources based on the roles and responsibilities of the users. The following measures are used for IAM:
Implementing identity and access management solutions: IAM solutions can manage user identities, assign user roles and responsibilities, authenticate and provide access control policies.
Multi-factor authentication: Multi-factor authentication can add an extra layer of security to the login process.
Auditing capabilities: Auditing capabilities can monitor user activity and detect potential security threats.
2.6. Runtime Container Security:
To keep its containers safe, businesses should employ a defense-in-depth strategy, as part of runtime protection.
Malicious processes, files, and network activity that deviates from a baseline can be detected and blocked via runtime container security.
Container runtime protection can give an extra layer of defense against malicious code on top of the network security provided by containerized next-generation firewalls.
In addition, HTTP layer 7 based threats like the OWASP Top 10, denial of service (DoS), and bots can be prevented with embedded web application and API security.
2.7. Compliance and Auditing:
Compliance and auditing ensure that the container infrastructure complies with relevant regulatory and industry standards. The following measures are used for compliance and auditing:
Monitoring and auditing capabilities: Monitoring and auditing capabilities can detect and report cloud security incidents and violations.
Compliance frameworks: Compliance frameworks can be used to ensure that the container infrastructure complies with relevant regulatory and industry standards, such as HIPAA, PCI DSS, and GDPR.
Enabling data access logs on AWS S3 buckets containing high-risk Confidential Data is one such example.
3. Conclusion
IaaS container security is critical for organizations that rely on containerization technology for deploying and managing their applications. There is likely to be an increased focus on the increased use of AI and ML to detect and respond to security incidents in real-time, the adoption of more advanced encryption techniques to protect data, and the integration of security measures into the entire application development lifecycle.
In order to stay ahead of the challenges and ensure the continued security of containerized applications, the ongoing process of IaaS container security requires continuous attention and improvement. By prioritizing security and implementing effective measures, organizations can confidently leverage the benefits of containerization while maintaining the confidentiality and integrity of their applications and data.
