VIRTUAL PRIVATE NETWORK SECURITY – IS IT A MYTH?

VPN may not be as secure as you think. If you are targeting overall VPN security, it is not difficult, and the best option is to add an extra security layer to your network. A certified network defender has the ability to plan and secure an organization’s network that includes VPN too. If you are on a virtual private network (VPN) and think that you are playing safe, then you may not be aware of may network security facts on VPN. IPv6 is a new protocol as the internet has exhausted IPv4 addresses and many VPNs have not adopted the change. Before we talk about how secure a VPN is, let us first understand what a virtual private network is. The following video by Android Authority explains what is a VPN is and how it works.

VMware Tanzu Kubernetes Grid Integrated: A Year in Review

Article | May 18, 2023

The modern application world is advancing at an unprecedented rate. However, the new possibilities these transformations make available don’t come without complexities. IT teams often find themselves under pressure to keep up with the speed of innovation. That’s why VMware provides a production-ready container platform for customers that aligns to upstream Kubernetes, VMware Tanzu Kubernetes Grid Integrated (formerly known as VMware Enterprise PKS). By working with VMware, customers can move at the speed their businesses demand without the headache of trying to run their operations alone. Our offerings help customers stay current with the open source community's innovations while having access to the support they need to move forward confidently. Many changes have been made to Tanzu Kubernetes Grid Integrated edition over the past year that are designed to help customers keep up with Kubernetes advancements, move faster, and enhance security. Kubernetes updates The latest version, Tanzu Kubernetes Grid Integrated 1.13, bumped to Kubernetes version 1.22 and removed beta APIs in favor of stable APIs that have since evolved from the betas. Over time, some APIs will evolve. Beta APIs typically evolve more often than stable APIs and should therefore be checked before updates occur. The APIs listed below will not be served with v1.22 as they have been replaced by more stable API versions: Beta versions of the ValidatingWebhookConfiguration and MutatingWebhookConfiguration API (the admissionregistration.k8s.io/v1beta1 API versions) The beta CustomResourceDefinition API (apiextensions.k8s.io/v1beta1) The beta APIService API (apiregistration.k8s.io/v1beta1) The beta TokenReview API (authentication.k8s.io/v1beta1) Beta API versions of SubjectAccessReview, LocalSubjectAccessReview, SelfSubjectAccessReview (API versions from authorization.k8s.io/v1beta1) The beta CertificateSigningRequest API (certificates.k8s.io/v1beta1) The beta Lease API (coordination.k8s.io/v1beta1) All beta Ingress APIs (the extensions/v1beta1 and networking.k8s.io/v1beta1 API versions) Containerd support Tanzu Kubernetes Grid Integrated helps customers eliminate lengthy deployment and management processes with on-demand provisioning, scaling, patching, and updating of Kubernetes clusters. To stay in alignment with the Kubernetes community, Containerd will be used as the default container runtime, although Docker can still be selected using the command-line interface (CLI) if needed. Networking Several updates have been made in regards to networking as well including support of Antrea and NSX-T enhancements. Antrea support With Tanzu Kubernetes Grid Integrated version 1.10 and later, customers can leverage Antrea on install or upgrade to use Kubernetes network policies. This enables enterprises to get the best of both worlds: access to the latest innovation from Antrea and world-class support from VMware. NSX-T enhancements NSX-T was integrated with Tanzu Kubernetes Grid Integrated to simplify container networking and increase security. This has been enhanced so customers can now choose the policy API as an option on a fresh installation of Tanzu Kubernetes Grid Integrated. This means that users will have access to new features available only through NSX-T policy API. This feature is currently in beta. In addition, more NSX-T and NSX Container Plug-in (NCP) configuration is possible through the network profiles. This operator command provides the benefit of being able to set configurations through the CLI, and this is persistent across lifecycle events. Storage enhancements We’ve made storage operations in our customers’ container native environments easier, too. Customers were seeking a simpler and more secure way to manage Container Storage Interface (CSI), and we introduced automatic installation of the vSphere CSI driver as a BOSH process beginning with Tanzu Kubernetes Grid Integrated 1.11. Also, as VCP will be deprecated, customers are advised to use the CSI driver. VCP-to-CSI migration is a part of Tanzu Kubernetes Grid Integrated 1.12 and is designed to help customers move forward faster. Enhanced security Implementing new technologies provides users with new capabilities, but it can also lead to new security vulnerabilities if not done correctly. VMware’s goal is to help customers move forward with ease and the confidence of knowing that enhancements don’t compromise core security needs. CIS benchmarks This year, Tanzu Kubernetes Grid Integrated continued to see improvements that help meet today’s high security standards. Meeting the Center for Internet Security (CIS) benchmarks standards is vital for Tanzu Kubernetes Grid Integrated. In recent Tanzu Kubernetes Grid Integrated releases, a few Kubernetes-related settings have been adjusted to ensure compliance with CIS requirements: Kube-apiserver with --kubelet-certificate-authority settings (v1.12) Kube-apiserver with --authorization-mode argument includes Node (v1.12) Kube-apiserver with proper --audit-log-maxage argument (v1.13) Kube-apiserver with proper --audit-log-maxbackup argument (v1.13) Kube-apiserver with proper --audit-log-maxsize argument (v1.13) Certificate rotations Tanzu Kubernetes Grid Integrated secures all communication between its control plane components and the Kubernetes clusters it manages, using TLS validated by certificates. The certificate rotations have been simplified in recent releases. Customers can now list and simply update certificates on a cluster-by-cluster basis through the “tkgi rotate-certificates” command. The multistep, manual process was replaced with a single CLI command to rotate NSX-T certificates (available since Tanzu Kubernetes Grid Integrated 1.10) and cluster-by-cluster certificates (available since Tanzu Kubernetes Grid Integrated 1.12). Hardening of images Tanzu Kubernetes Grid Integrated keeps OS images, container base images, and software library versions updated to remediate the CVEs reported by customers and in the industry. It also continues to use the latest Ubuntu Xenial Stemcell latest versions for node virtual machines. With recent releases and patch versions, the version of dockerd, containerd, runc, telegraf, nfs-utils had been bumped to the latest stable and secure versions as well. By using Harbor as a private registry management service, customers could also leverage the built-in vulnerability scan features to discover the application images CVEs. VMware is dedicated to supporting customers with production readiness by enhancing the user experience. Tanzu Kubernetes Grid Integrated Edition has stayed up to date with the Kubernetes community and provides customers with the support and resources they need to innovate rapidly.

Virtual Machine Security Risks and Mitigation in Cloud Computing

Article | August 12, 2022

Analyzing risks and implementing advanced mitigation strategies: Safeguard critical data, fortify defenses, and stay ahead of emerging threats in the dynamic realm of virtual machines in cloud. Contents 1. Introduction 2. 10 Security Risks Associated with Virtual Machines in Cloud Computing 3. Best Practices to Avoid Security Compromise 4. Conclusion 1. Introduction Cloud computing has revolutionized the way businesses operate by providing flexible, scalable, and cost-effective infrastructure for running applications and services. Virtual machines (VMs) are a key component of cloud computing, allowing multiple virtual machines to run on a single physical machine. However, the use of virtual machines in cloud computing introduces new security risks that need to be addressed to ensure the confidentiality, integrity, and availability of data and services. Effective VM security in the cloud requires a comprehensive approach that involves cloud providers and users working together to identify and address potential virtual machine security threats. By implementing these best practices and maintaining a focus on security, cloud computing can provide a secure and reliable platform for businesses to run their applications and services. 2. 10 Security Risks Associated with Virtual Machines in Cloud Computing Denial of Service (DoS) attacks: These are attacks that aim to disrupt the availability of a VM or the entire cloud infrastructure by overwhelming the system with traffic or resource requests. Insecure APIs: Cloud providers often expose APIs that allow users to manage their VMs. If these APIs are not properly secured, attackers can exploit them to gain unauthorized access to VMs or manipulate their configurations. Data leakage: Virtual machines can store sensitive data such as customer information or intellectual property. If not secured, this data can be exposed to unauthorized access or leakage. Shared resources: VMs in cloud environments often share physical resources such as memory, CPU, and network interfaces. If these resources are not isolated, a compromised VM can potentially affect the security and performance of other VMs running on the same physical host. Lack of visibility: Virtual machines in cloud environments can be more difficult to monitor than physical machines. This can make it harder to detect security incidents or anomalous behavior. Insufficient logging and auditing: If cloud providers do not implement appropriate logging and auditing mechanisms, it can be difficult to determine the cause and scope of a security incident. VM escape: This is when an attacker gains access to the hypervisor layer and then escapes into the host operating system or other VMs running on the same physical host. Side-channel attacks: This is when an attacker exploits the physical characteristics of the hardware to gain unauthorized access to a VM. Examples of side-channel attacks include timing attacks, power analysis attacks, and electromagnetic attacks. Malware attacks: VMs can be infected with malware, just like physical machines. Malware can be used to steal data, launch attacks on other VMs or systems, or disrupt the functioning of the VM. Insider threats: Malicious insiders can exploit their access to VMs to steal data, modify configurations, or launch attacks. 3. Best Practices to Avoid Security Compromise To mitigate these risks, there are several virtual machine security guidelines that cloud service providers and users can follow: Keep software up-to-date: Regularly updating software and security patches for virtual machines is crucial in preventing known vulnerabilities from being exploited by hackers. Software updates fix bugs and security flaws that could allow unauthorized access, data breaches, or malware attacks. According to a study, 60% of data breaches are caused by vulnerabilities that were not patched or updated in a timely manner.(Source: Ponemon Institute) Use secure hypervisors: A hypervisor is a software layer that enables multiple virtual machines to run on a single physical server. Secure hypervisors are designed to prevent unauthorized access to virtual machines and protect them from potential security threats. When choosing a hypervisor, it is important to select one that has undergone rigorous testing and meets industry standards for security. In 2018, a group of researchers discovered a new type of attack called "Foreshadow" (also known as L1 Terminal Fault). The attack exploits vulnerabilities in Intel processors and can be used to steal sensitive data from virtual machines running on the same physical host. Secure hypervisors that have implemented hardware-based security features can provide protection against Foreshadow and similar attacks. (Source: Foreshadow) Implement strong access controls: Access control is the practice of restricting access to virtual machines to authorized users. Multi-factor authentication adds an extra layer of security by requiring users to provide more than one type of authentication method before accessing VMs. Strong access controls limit the risk of unauthorized access and can help prevent data breaches. According to a survey, organizations that implemented multi-factor authentication saw a 98% reduction in the risk of phishing-related account breaches. (Source: Duo Security) Monitor VMs for anomalous behavior: Monitoring virtual machines for unusual or unexpected behavior is an essential security practice. This includes monitoring network traffic, processes running on the VM, and other metrics that can help detect potential security incidents. By monitoring VMs, security teams can detect and respond to security threats before they can cause damage. A study found that 90% of organizations that implemented a virtualized environment experienced security benefits, such as improved visibility into security threats and faster incident response times. (Source: VMware) Use Encryption: Encryption is the process of encoding information in such a way that only authorized parties can access it. Encrypting data both in transit and at rest protects it from interception or theft by hackers. This can be achieved using industry-standard encryption protocols and technologies. According to a report by, the average cost of a data breach in 2020 was $3.86 million. The report also found that organizations that implemented encryption had a lower average cost of a data breach compared to those that did not (Source: IBM) Segregate VMs: Segregating virtual machines is the practice of keeping sensitive VMs separate from less sensitive ones. This reduces the risk of lateral movement, which is when a hacker gains access to one VM and uses it as a stepping stone to gain access to other VMs in the same environment. Segregating VMs helps to minimize the risk of data breaches and limit the potential impact of a security incident. A study found that organizations that implemented a virtualized environment without adequate segregation and access controls were more vulnerable to VM security breaches and data loss. (Source: Ponemon Institute) Regularly Back-up VMs: Regularly backing up virtual machines is a critical security practice that can help mitigate the impact of malware attacks, system failures, or other security incidents. Backups should be stored securely and tested regularly to ensure that they can be restored quickly in the event of a security incident. A survey conducted found that 42% of organizations experienced a data loss event in 2020 with the most common cause being accidental deletion by an employee (29%). (Source: Veeam) 4. Conclusion The complexity of cloud environments and the shared responsibility model for security require organizations to adopt a comprehensive security approach that spans multiple infrastructure layers, from the physical to the application layer. The future of virtual machine security concern in cloud computing will require continued innovation and adaptation to new threats and vulnerabilities. As a result, organizations must remain vigilant and proactive in their security efforts, leveraging the latest technologies and best practices to protect their virtual machines, the sensitive data and resources they contain.

Managing Multi-Cloud Complexities for a Seamless Experience

Article | July 7, 2022

Introduction The early 2000s were milestone moments for the cloud. Amazon Web Services (AWS) entered the market in 2006, while Google revealed its first cloud service in 2007. Fast forward to 2020, when the pandemic boosted digital transformation efforts by around seven years (according to McKinsey), and the cloud has become a commercial necessity today. It not only facilitated the swift transition to remote work, but it also remains critical in maintaining company sustainability and creativity. Many can argue that the large-scale transition to the cloud in the 2010s was necessary to enable the digital-first experiences that remote workers and decentralized businesses need today. Multi-cloud and hybrid cloud setups are now the norm. According to Gartner, most businesses today use a multi-cloud approach to reduce vendor lock-in or to take advantage of more flexible, best-of-breed solutions. However, managing multi-cloud systems increases cloud complexity, and IT concerns, frequently slowing rather than accelerating innovation. According to 2022 research done by IntelligentCIO, the average multi-cloud system includes five platforms, including AWS, Microsoft Azure, Google Cloud, and IBM Red Hat, among others. Managing Multi-Cloud Complexities Like a Pro Your multi-cloud strategy should satisfy your company's requirements while also laying the groundwork for managing various cloud deployments. Creating a proactive plan for managing multi-cloud setups is one of the finest features that can distinguish your company. The five strategies for handling multi-cloud complexity are outlined below. Managing Data with AI and ML AI and machine learning can help manage enormous quantities of data in multi-cloud environments. AI simulates human decision-making and performs tasks as well as humans or even better at times. Machine learning is a type of artificial intelligence that learns from data, recognizes patterns, and makes decisions with minimum human interaction. AI and ML to help discover the most important data, reducing big data and multi-cloud complexity. AI and machine learning enable more simplicity and better data control. Integrated Management Structure Keeping up with the growing number of cloud services from several providers requires a unified management structure. Multiple cloud management requires IT time, resources, and technology to juggle and correlate infrastructure alternatives. Routinely monitor your cloud resources and service settings. It's important to manage apps, clouds, and people globally. Ensure you have the technology and infrastructure to handle several clouds. Developing Security Strategy Operating multiple clouds requires a security strategy and seamless integration of security capabilities. There's no single right answer since vendors have varied policies and cybersecurity methods. Storing data on many cloud deployments prevents data loss. Handling backups and safety copies of your data are crucial. Regularly examine your multi-cloud network's security. The cyber threat environment will vary as infrastructure and software do. Multi-cloud strategies must safeguard data and applications. Skillset Management Multi-cloud complexity requires skilled operators. Do you have the appropriate IT personnel to handle multi-cloud? If not, can you use managed or cloud services? These individuals or people are in charge of teaching the organization about how each cloud deployment helps the company accomplish its goals. This specialist ensures all cloud entities work properly by utilizing cloud technologies. Closing Lines Traditional cloud monitoring solutions are incapable of dealing with dynamic multi-cloud setups, but automated intelligence is the best at getting to the heart of cloud performance and security concerns. To begin with, businesses require end-to-end observability in order to see the overall picture. Add automation and causal AI to this capacity, and teams can obtain the accurate answers they require to better optimize their environments, freeing them up to concentrate on increasing innovation and generating better business results.

Multi-cloud strategies must safeguard data and applications. Skillset Management Multi-cloud complexity requires skilled operators. Do you have the appropriate IT personnel to handle multi-cloud? If not, can you use managed or cloud services? These individuals or people are in charge of teaching the organization about how each cloud deployment helps the company accomplish its goals. This specialist ensures all cloud entities work properly by utilizing cloud technologies. Closing Lines Traditional cloud monitoring solutions are incapable of dealing with dynamic multi-cloud setups, but automated intelligence is the best at getting to the heart of cloud performance and security concerns. To begin with, businesses require end-to-end observability in order to see the overall picture. Add automation and causal AI to this capacity, and teams can obtain the accurate answers they require to better optimize their environments, freeing them up to concentrate on increasing innovation and generating better business results.

Minimize the Cost and Downtime of Disaster With Scale Computing's Business Continuity/Disaster Recovery Planning Service

PR Newswire | October 25, 2023

Scale Computing, a market leader in edge computing, virtualization, and hyperconverged solutions, today announced its Business Continuity/Disaster Recovery (BCDR) Planning Service, designed to help organizations establish a comprehensive, regulated plan for responding to unforeseen downtime. The service provides Scale Computing customers and partners with the tools, guidance, and resources to create a playbook for data backup and recovery, enabling businesses to endure a disaster scenario with minimal loss. Scale Computing also recently announced that it is a finalist for the Business Continuity/Disaster Recovery Project of the Year in the 2023 SDC Awards for its work with Austrian managed service provider GiGaNet and its long-time partner the Zillertaler Gletscherbahn group. Voting for the SDC Awards is open at sdcawards.com/vote until November 10th, 2023. Data breaches are one of the biggest and most costly contributors to downtime for businesses. In 2023, the average cost of a data breach globally reached an all-time high of $4.45 million, a 15.3% increase from 2020. Simultaneously, the average length of business disruption following a ransomware attack in the United States reached 24 days last year, up 60% from just two years prior — a significant increase when downtime costs exceed $300,000 per hour for over 90% of mid-sized and large enterprises. For more than half of those businesses, the hourly outage costs range from $1 million to over $5 million. Recovery from an outage adds additional expense from which many enterprises are unable to bounce back. "Disaster can strike at any time, and every organization needs a consistently regulated playbook for how the business will respond — from action plans to recovery plans for bringing online the mission-critical servers businesses depend on," said Jeff Ready, CEO and co-founder, Scale Computing. "Knowing what systems need to be protected, planning for the ability to recover them, and having a full action plan for recovery should be at the forefront of every IT department's agenda, at the beginning of any infrastructure addition. With Scale Computing Platform, the plan for disaster recovery starts before equipment is even put into production, so IT leaders have a plan in place from day one that they can enact to ensure their business stays up and running, with minimal loss, should disaster strike. Our Business Continuity/Disaster Recovery Planning Service enables businesses to proactively classify systems based on their importance and implement a robust action plan, ensuring that our customers' and partners' critical systems are protected, validated, tested, and ready for recovery at any time." Whether a minor data loss or a business-wide shutdown, having a well-defined business continuity strategy is crucial to minimize financial impact, ensure continuous employee productivity, meet compliance and regulatory requirements, decrease liability obligations, reduce downtime, and minimize the risk of negative exposure. Scale Computing's BCDR Planning Service includes planning, deployment, documentation creation, and disaster recovery testing, covering every aspect to keep businesses prepared and resilient.
