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.

The success of 5G technology is a function of both the infrastructure that supports it and the ecosystems that enable it. Today, the definitive focus in the 5G space is on enterprise use cases, ranging from dedicated private 5G networks to accessing edge compute infrastructure and public or private clouds from the public 5G network. As a result, vendor-neutral multitenant data center providers and their rich interconnection capabilities are pivotal in helping make 5G a reality. This is true both in terms of the physical infrastructure needed to support 5G and the ability to effectively connect enterprises to 5G.
Industry experts expect 5G to enable emerging applications such as virtual and augmented reality (AR/VR), industrial robotics/controls as part of the industrial internet of things (IIoT), interactive gaming, autonomous driving, and remote medical procedures. These applications need a modern, cloud-based infrastructure to meet requirements around latency, cost, availability and scalability. This infrastructure must be able to provide real-time, high-bandwidth, low-latency access to latency-dependent applications distributed at the edge of the network.
How Equinix thinks about network slicing
Network slicing refers to the ability to provision and connect functions within a common physical network to provide the resources necessary to deliver service functionality under specific performance constraints (such as latency, throughput, capacity and reliability) and functional constraints (such as security and applications/services). With network slicing, enterprises can use 5G networks and services for a wide variety of use cases on the same infrastructure.
Providing continuity of network slices with optimal UPF placement and intelligent interconnection
Mobile traffic originates in the mobile network, but it is not contained to the mobile network domain, because it runs between the user app on a device and the server workload on multi-access edge compute (MEC) or on the cloud. Therefore, to preserve intended characteristics, the slice must be extended all the way to where the traffic wants to go. This is why we like to say “the slicing must go on.”
The placement of network functions within the slice must be optimized relative to the intended traffic flow, so that performance can be ensured end-to-end. As a result, organizations must place or activate the user plane function (UPF) in optimal locations relative to the end-to-end user plane traffic flow.
We expect that hybrid and multicloud connectivity will remain a key requirement for enterprises using 5G access. In this case, hybrid refers to private edge computing resources (what we loosely call “MEC”) located in data centers—such as Equinix International Business Exchange™ (IBX®) data centers—and multicloud refers to accessing multiple cloud providers from 5G devices. To ensure both hybrid and multicloud connectivity, enterprises need to make the UPF part of the multidomain virtual Layer 2/Layer 3 interconnection fabric.
Because a slice must span multiple domains, automation of UPF activation, provisioning and virtual interconnection to edge compute and multicloud environments is critical.
Implementing network slicing for interconnection of core and edge technology
Equinix partnered with Kaloom to develop network slicing for interconnection of core and edge (NICE) technology within our 5G and Edge Technology Development Center (5G ETDC) in Dallas. NICE technology is built using cloud-native network fabric and high-performance 5G UPF from Kaloom. This is a production-ready software solution, running on white boxes built with P4 programmable application-specific integrated circuits (ASICs), allowing for deep network slicing and support for high-performance 5G UPF with extremely fast data transfer rates.
With NICE technology in the 5G ETDC, Equinix demonstrates:
5G UPF deployment/activation and traffic breakout at Equinix for multiple slices.
Software-defined interconnection between the 5G core and MEC resources from multiple providers.
Software-defined interconnection between the 5G core and multiple cloud service providers.
Orchestration of provisioning and automation of interconnection across the 5G core, MEC and cloud resources.

This demonstrates the benefit of having the UPF as a feature of the interconnection fabric, effectively allowing UPF activation as part of the virtual fabric configuration. This ultimately enables high-performance UPF that’s suitable for use cases such as high-speed 5G fixed wireless access.
Combining UPF instances and MEC environments into an interconnection fabric makes it possible to create continuity for the slices and influence performance and functionality. Equinix Fabric adds multicloud connectivity to slices, enabling organizations to directly integrate network slicing with their mobile hybrid multicloud architectures.
Successful private 5G edge deployments deliver value in several ways. Primarily, they offer immediate access to locally provisioned elastic compute, storage and networking resources that deliver the best user and application experiences. In addition, they help businesses access a rich ecosystem of partners to unlock new technologies at the edge.
Secure, reliable connectivity and scalable resources are essential at the edge. A multivendor strategy with best-of-breed components complemented by telemetry, advanced analytics with management and orchestration—as demonstrated with NICE in Equinix data centers—is a most effective way to meet those requirements. With Equinix’s global footprint of secure, well-equipped facilities, customers can maximize benefits.”
- Suresh Krishnan, CTO, Kaloom
Equinix and its partners are building the future of 5G
NICE technology is just one example of how the Equinix 5G and Edge Technology Development Center enables the innovation and development of real-world capabilities that underpin the edge computing and interconnection infrastructure required to successfully implement 5G use cases. A key benefit of the 5G ETDC is the ability to combine cutting-edge innovations from our partners like Kaloom with proven solutions from Equinix that already serve a large ecosystem of customers actively utilizing hybrid multicloud architectures.

We’re all hoping that 2022 will finally end the unprecedented challenges brought by the global pandemic and things will return to a new normalcy. For IT infrastructure and operations organizations, the rising trends that we are seeing today will likely continue, but there are still a few areas that will need special attention from IT leaders over the next 12 to 18 months.
In no particular order, they include:
The New Edge
Edge computing is now at the forefront. Two primary factors that make it business-critical are the increased prevalence of remote and hybrid workplace models where employees will continue working remotely, either from home or a branch office, resulting in an increased adoption of cloud-based businesses and communications services.
With the rising focus on remote and hybrid workplace cultures, Zoom, Microsoft Teams, and Google Meet have continued to expand their solutions and add new features. As people start moving back to office, they are likely to want the same experience they had from home. In a typical enterprise setup, branch office traffic is usually backhauled all the way to the data center. This architecture severely impacts the user experience, so enterprises will have to review their network architectures and come up with a roadmap to accommodate local egress between branch offices and headquarters. That’s where the edge can help, bringing it closer to the workforce.
This also brings an opportunity to optimize costs by migrating from some of the expensive multi-protocol label switching (MPLS) or private circuits to relatively low-cost direct internet circuits, which is being addressed by the new secure access service edge (SASE) architecture that is being offered by many established vendors.
I anticipate some components of SASE, specifically those related to software-defined wide area network (SD-WAN), local egress, and virtual private network (VPN), will drive a lot of conversation this year.
Holistic Cloud Strategy
Cloud adoption will continue to grow, and along with software as a service (SaaS), there will be renewed interest in infrastructure as a service (IaaS), albeit for specific workloads. For a medium-to-large-sized enterprise with a substantial development environment, it will still be cost-prohibitive to move everything to the cloud, so any cloud strategy would need to be holistic and forward-looking to maximize its business value.
Another pandemic-induced shift is from using virtual machines (VMs) as a consumption unit of compute to containers as a consumption unit of software. For on-premises or private cloud deployment architectures that require sustainable management, organizations will have to orchestrate containers and deploy efficient container security and management tools.
Automation
Now that cloud adoption, migration, and edge computing architectures are becoming more prevalent, the legacy methods of infrastructure provisioning and management will not be scalable.
By increasing infrastructure automation, enterprises can optimize costs and be more flexible and efficient—but only if they are successful at developing new skills. To achieve the goal of “infrastructure as a code” will require a shift in the perspective on infrastructure automation to one that focuses on developing and sustaining skills and roles that improve efficiency and agility across on-premises, cloud, and edge infrastructures. Defining the roles of designers and architects to support automation is essential to ensure that automation works as expected, avoids significant errors, and complements other technologies.
AIOps (Artificial Intelligence for IT Operations)
Alongside complementing automation trends, the implementation of AIOps to effectively automate IT operations processes such as event correlation, anomaly detection, and causality determination will also be important. AIOps will eliminate the data silos in IT by bringing all types of data under one roof so it can be used to execute machine learning (ML)-based methods to develop insights for responsive enhancements and corrections.
AIOps can also help with probable cause analytics by focusing on the most likely source of a problem. The concept of site reliability engineering (SRE) is being increasingly adopted by SaaS providers and will gain importance in enterprise IT environments due to the trends listed above. AIOps is a key component that will enable site reliability engineers (SREs) to respond more quickly—and even proactively—by resolving issues without manual intervention.
These focus areas are by no means an exhaustive list. There are a variety of trends that will be more prevalent in specific industry areas, but a common theme in the post-pandemic era is going to be superior delivery of IT services. That’s also at the heart of the Autonomous Digital Enterprise, a forward-focused business framework designed to help companies make technology investments for the future.
