IT Simplified: Network Firewall

A firewall is a network security device, either hardware or software-based, which monitors all incoming and outgoing traffic and based on a defined set of security rules it accepts, rejects or drops that specific traffic.A firewall establishes a barrier between secured internal networks and outside untrusted network, such as the Internet.

History and Need for Firewall

Before Firewalls, network security was performed by Access Control Lists (ACLs) residing on routers. ACLs are rules that determine whether network access should be granted or denied to specific IP address.But ACLs cannot determine the nature of the packet it is blocking. Also, ACL alone does not have the capacity to keep threats out of the network. Hence, the Firewall was introduced.

How Firewall Works

Firewall match the network traffic against the rule set defined in its table. Once the rule is matched, associate action is applied to the network traffic. For example, Rules are defined as any employee from HR department cannot access the data from code server and at the same time another rule is defined like system administrator can access the data from both HR and technical department. Rules can be defined on the firewall based on the necessity and security policies of the organization.

From the perspective of a cooperate business, network traffic can be either outgoing or incoming. Firewall maintains a distinct set of rules for both the cases. Mostly the outgoing traffic, originated from the server itself, allowed to pass. Still, setting a rule on outgoing traffic is always better in order to achieve more security and prevent unwanted communication.

IT Simplified: Software Define Storage

What Is Software-Designed Storage?

Software-designed storage (SDS) is a storage architecture that decouples storage software from its hardware, giving you greater scalability, flexibility, and control over your data storage infrastructure.

Why Decouple Storage Software from Data Storage Infrastructure?

IT Simplified: Intel vPro Technology

Intel vPro is an integrated suite of business-class technologies with built-in stability, performance, and security tools. This platform helps businesses of all sizes to scale quickly, pivot faster and manage the IT environment of the company. 

Intel vPro is a amalgamations of the below technologies:

1.    Security Powered by Intel® Threat Detection Technology (TDT) within Intel Hardware Shield: 

•    Identify threats, detect abnormal activities and remediate them while off-loading security workloads to the GPU.
•    Identify unauthorized changes to hardware and firmware by providing visibility into how the OS and BIOS use hardware protection.
•    Prevent memory corruption and malware injection by isolating different workspaces and reducing attack surfaces.

IT Simplified: Cloud Native

Cloud-native is a term used to describe applications that are built to run in a cloud computing environment. These applications are designed to be scalable, highly available, and easy to manage.

By contrast, traditional solutions are often designed for on-premise environments and then adapted for the cloud. This can lead to sub-optimal performance and increased complexity.

As enterprises move more of their workloads to the cloud, they increasingly looking for solutions that are cloud-native. Cloud-native solutions are designed from the ground up to take advantage of the unique characteristics of the cloud, such as scalability, elasticity, and agility.
Because cloud native applications are architectured using microservices instead of a monolithic application structure, they rely on containers to package the application’s libraries and processes for deployment. Microservices allow developers to build deployable apps that are composed as individual modules focused on performing one specific service. This decentralization makes for a more resilient environment by limiting the potential of full application failure due to an isolated problem.

Container orchestration tools, like Kubernetes, allow developers to coordinate the way in which an application’s containers will function, including scaling and deployment.

Cloud native app development requires a shift to a DevOps operating structure. This means development and operations teams will work much more collaboratively, leading to a faster and smoother production process.

IT Simplified: Service Catalogue

IT departments are facing pressures to align their IT services with business needs, develop standardized processes and improve the IT customer experience and IT customer satisfaction, all while keeping costs low.  Arguably one of the best ways to achieve this is through a Service Catalog.

A Service Catalog is the store front (or directory) of services available to the enterprise user. This includes setting expectations (what you get, when, how, at what cost) and proper measurement of those expectations to determine if they have been met or exceeded In essence, a Service Catalog helps IT departments demonstrate the value and innovation they deliver to the business and help enterprise users to access the right services at the right time, to be more productive and do their job more effectively.

IT Simplified: Business Continuity and Disaster Recovery

A business continuity and disaster recovery plan is a broad guide designed to keep a business running, even in the event of a disaster. This plan focuses on the business as a whole, but drills down to specific scenarios that might create operational risks. With business continuity planning, the aim is to keep critical operations functioning, so that your business can continue to conduct regular business activities even under unusual circumstances.

IT Simplified: SASE

SASE (pronounced “sassy”), is an emerging cybersecurity concept that Gartner’s Andrew Lerner defines as “the convergence of wide area networking (WAN) and network security services like CASB, FWaaS and Zero Trust (ZTNA) into a single, cloud-native service model.The shift to a secure access service edge (SASE) solution is rapidly increasing as hybrid work and cloud computing continue to excel.

SASE combines software-defined wide area networking (SD-WAN) capabilities with a number of network security functions, all of which are delivered from a single cloud platform. In this way, SASE enables employees to authenticate and securely connect to internal resources from anywhere, and gives organizations better control over the traffic and data that enters and leaves their internal network. In this SASE architecture definition, users are provided modern cloud-first architecture for both WAN and security functions, all delivered and managed in the cloud.

IT Simplified: Remote Display Technologies

Remote access technology refers to any IT toolset used to connect to, access, and control devices, resources, and data stored on a local network from a remote geographic location. 

This makes remote access crucial for businesses of all sizes which have not moved to a cloud-first model, or which require access to on-premises machines or resources. Three of the most common remote access technologies – Remote Desktop Services, Remote Access Software, and Virtual Private Networks – are examined in brief.
