Data-hungry workloads in your VMware vSAN based data center?

One of the questions that comes up often when I meet architects around the world designing data center modernization with Hyper Converged Infrastructure (HCI) is, “How important is the hardware for HCI deployment?” Given HCI solutions are software-defined and the software magically virtualizes and manages all of the compute, storage and networking features, users sometimes forget that it can only virtualize hardware that is actually there. HCI has matured over the years and is now deployed in mission critical data centers because of its ability to offer various storage features on par with traditional arrays, while scaling-out storage as needed. HCI software, no matter how optimized, needs to have the right hardware configurations to support the software optimizations in order to optimize performance. The HCI software storage features, when enabled, take significant compute and storage cycles. Proper consideration must be taken to understand this when choosing the right hardware components to design HCI clusters.

Why Are Businesses Tilting Towards VDI for Remote Employees?

Article | April 28, 2023

Although remote working or working from home became popular during the COVID era, did you know that the technology that gives the best user experience (UX) for remote work was developed more than three decades ago? Citrix was founded in 1989 as one of the first software businesses to provide the ability to execute any program on any device over any connection. In 2006, VMware coined the term "virtual desktop infrastructure (VDI)" to designate their virtualization products. Many organizations created remote work arrangements in response to the COVID-19 pandemic, and the phenomenon will continue even in 2022. Organizations have used a variety of methods to facilitate remote work over the years. For businesses, VDI has been one of the most effective, allowing businesses to centralize their IT resources and give users remote access to a consolidated pool of computing capacity. Reasons Why Businesses Should Use VDI for their Remote Employees? Companies can find it difficult to scale their operations and grow while operating remotely. VDI, on the other hand, can assist in enhancing these efforts by eliminating some of the downsides of remote work. Device Agnostic As long as employees have sufficient internet connectivity, virtual desktops can accompany them across the world. They can use a tablet, phone, laptop, client side, or Mac to access the virtual desktop. Reduced Support Costs Since VDI setups can often be handled by a smaller IT workforce than traditional PC settings, support expenses automatically go down. Enhanced Security Data security is raised since data never leaves the datacenter. There's no need to be concerned about every hard disk in every computer containing sensitive data. Nothing is stored on the end machine while using the VDI workspace. It also safeguards intellectual property while dealing with contractors, partners, or a worldwide workforce. Comply with Regulations With virtual desktops, organizational data never leaves the data center. Remote employees that have regulatory duties to preserve client/patient data like function because there is no risk of data leaking out from a lost or stolen laptop or retired PC. Enhanced User Experience With a solid user experience (UX), employees can work from anywhere. They can connect to all of their business applications and tools from anywhere they want to call your workplace, exactly like sitting at their office desk, and even answer the phone if they really want to. Closing Lines One of COVID-19's lessons has been to be prepared for almost anything. IT leaders were probably not planning their investments with a pandemic in mind. Irrespective of how the pandemic plays out in the future, the rise of remote work is here to stay. If VDI at scale is to become a permanent feature of business IT strategies, now is the moment to assess where, when, and how your organization can implement the appropriate solutions. Moreover, businesses that use VDI could find that the added flexibility extends their computing refresh cycles.

Metasploitable: A Platform for Ethical Hacking and Penetration Testing

Article | June 8, 2023

Contents 1. Overview 2. Ethical Hacking and Penetration Testing 3. Metasploit Penetration Test 4. Why Choose Metasploit Framework for your Business? 5. Closing remarks 1. Overview Metasploitable refers to an intentionally vulnerable virtual machine that enables the learning and practice of Metasploit. Metasploit is one of the best penetration testing frameworks that helps businesses discover and shore up their systems' vulnerabilities before hackers exploit them. Security engineers use Metasploit as a penetration testing system and a development platform that allows the creation of security tools and exploits. Metasploit's various user interfaces, libraries, tools, and modules allow users to configure an exploit module, pair it with a payload, point it at a target, and launch it at the target system. In addition, Metasploit's extensive database houses hundreds of exploits and several payload options. 2. Ethical Hacking and Penetration Testing An ethical hacker is one who works within a security framework and checks for bugs that a malicious hacker might use to exploit networks. They use their experience and skills to render the cyber environment. To protect the infrastructure from the threat that hackers pose, ethical hacking is essential. The main purpose of an ethical hacking service is to report and assess the safety of the targeted systems and networks for the owner. Ethical hacking is performed with penetration test techniques to evaluate security loopholes. There are many techniques used to hack information, such as – Information gathering Vulnerability scanning Exploitation Test analysis Ethical hacking involves automatic methods. The hacking process without automated software is inefficient and time-consuming. There are several tools and methods that can be used for ethical hacking and penetration testing. The Metasploit framework eases the effort to exploit vulnerabilities in networks, operating systems, and applications and generates new exploits for new or unknown vulnerabilities. 3. Metasploit Penetration Test Reconnaissance: Integrate Metasploit with various reconnaissance tools to find the vulnerable spot in the system. Threat Modeling and Vulnerability Identification: Once a weakness is identified, choose an exploit and payload for penetration. Exploitation: The payload gets executed at the target if the exploit, a tool used to take advantage of system weakness, is successful, and the user gets a shell for interacting with the payload (a shellcode is a small piece of code used as the payload).The most popular payload, a set of malicious codes to attack Windows systems, is Meterpreter, an in-memory-only interactive shell. (Meterpreter is a Metasploit attack payload that provides an interactive shell for the attacker to explore the target machine and execute code.)Other payloads are: Static payloads (it enables port forwarding and communications between networks) Dynamic payloads (to evade antivirus software, it allows testers to generate unique payloads) Command shell payloads (enables users to run scripts or commands against a host) Post-Exploitation: Metasploit offers various exploitation tools for privilege escalation, packet sniffing, keyloggers, screen capture, and pivoting tools once on the target machine. Resolution and Re-Testing: Users set up a persistent backdoor if the target machine gets rebooted. These available features in Metasploit make it easy to configure as per the user's requirements. 4. Why Choose Metasploit Framework for your Business? Significant advantages of the Metasploit Framework are discussed below: Open-source: Metasploit Framework is actively developed as open-source software, so most companies prefer this to grow their businesses. Easy usage: It is very easy to use, defining an easy-naming conversation with the commands. This also facilitates the building of an extensive penetration test of the network. GUI Environment: It mainly provides third-party instances that are friendly. These interfaces ease the penetration testing projects by providing the facilities with services such as button clicks, over-the-fly vulnerability management, and easy-to-shift workspaces, among others. Cleaner Exits: Metasploit can cleanly exit without detection, even if the target system does not restart after a penetration test. Additionally, it offers various options for maintaining persistent access to the target system. Easy Switching Between Payloads: Metasploit allows testers to change payloads with the 'setpayload' command easily. It offers flexibility for system penetration through shell-based access or meterpreter. 5. Closing remarks From DevSecOps experts to hackers, everyone uses the Ruby-based open-source framework Metasploit, which allows testing via command-line alterations or GUI. Metasploitable is a vulnerable virtual machine ideally used for ethical hacking and penetration testing, in VM security. One trend likely to impact the future of Metasploitable is the increasing use of cloud-based environments for testing and production. It is possible that Metasploitable could be adapted to work in cloud environments or that new tools will be developed specifically for cloud-based penetration testing. Another trend that may impact the future of Metasploitable is the growing importance of automation in security testing. Thus, Metasploitable could be adapted to include more automation features. The future of Metasploitable looks bright as it continues to be a valuable tool for security professionals and enthusiasts. As the security landscape continues to evolve, it will be interesting to see how Metasploitable adapts to meet the community's changing needs.

Rising Importance of Network Virtualization

Article | July 26, 2022

Network virtualization combines network resources to integrate several physical networks, segment a network, or construct software networks among VMs. IT teams can construct numerous separate virtual networks using network virtualization. Virtual networks can be added and scaled without changing hardware. Teams can start up logical networks more rapidly in response to business needs using network virtualization. This adaptability improves service delivery, efficiency, and control. Importance of Network Virtualisation Network virtualization entails developing new rules for the delivery of network services. This involves software-defined data centers (SDDC), cloud computing, and edge computing. Virtualization assists in the transformation of networks from rigid, wasteful, and static to optimized, agile, and dynamic. To ensure agility and speed, modern virtual networks must keep up with the needs of cloud-hosted, decentralized applications while addressing cyberthreats. You can deploy and upgrade programs in minutes thanks to network virtualization. This eliminates the need to spend time setting up the infrastructure to accommodate the new applications. What is the Process of Network Virtualization? Several network functions that were previously done manually on hardware are now automated through network virtualisation. Network managers can construct, maintain, and provide networks programmatically in software while employing the hardware as a packet-forwarding backplane. Physical network resources, such as virtual private networks (VPNs), load balancing, firewalling, routing, and switching, are pooled and supplied in software. To do this, you merely require Internet Protocol (IP) packet forwarding from the hardware or physical network. Individual workloads, such as virtual machines, can access network services that have been distributed to a virtual layer. There are several kinds of virtual machines accessible. The finest virtual machines enable network administrators to access all parts of a network from a single point of access. Closing Lines Network virtualization will remain a critical component in both business and carrier network architectures. Network virtualization projects in the future will inevitably incorporate zero trust, automation, and edge and cloud computing.

How managed network services are evolving to simplify the global WAN

Networkworld | February 20, 2019

The managed network services market has traditionally been dominated by telcos that provide a common MPLS network, but that is slowly changing as new approaches are developed. Fundamentally, the way that carriers (i.e. telcos) deliver managed network services hasn’t changed in decades. The core architecture of this network, known as hub and spoke, consists of branches talking to the data center over a managed network with a separate firewall in the middle. However, this type of legacy WAN can’t support today’s business needs, which include a seminal shift to the cloud, as well as mobile users that need network access from anywhere, not just from the branch.
