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: 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: 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: Vulnerability Assessment & Testing.

Vulnerability Assessment and Penetration Testing is a security testing method  that examines an application, network, endpoint, or cloud for flaws  A VAPT audit is designed to test the overall security of a system by performing an in-depth security analysis of its various elements.Vulnerability Assessment and Penetration Testing serve different purpose but they are typically used together to generate a comprehensive security analysis.

The goal of a VAPT audit is to identify the overall vulnerabilities present in the software, which hackers can exploit. VAPT security audit is carried out through a systematic process involving various tools, techniques, and methodologies.

What is the purpose and benefits of VAPT?

Because hackers’ tools, strategies, and processes for breaching networks are constantly improving, it’s critical to assess the organization’s cyber security frequently.VAPT assists in the security of your organization by offering insight into security flaws as well as advice on how to remedy them. For organizations wishing to comply with standards such as the GDPR, ISO 27001, and PCI DSS, VAPT is becoming increasingly crucial.There are many benefits to conducting regular VAPT audits, including:

– Identifying and fixing security vulnerabilities before they can be exploited

– reducing the risk of data breaches and other cyber security incidents

– improving compliance with industry regulations such as PCI DSS

– demonstrating to customers and partners that your organisation takes security seriously

IT Simplified: IPsec

What is IPsec?

IPsec is a group of protocols that are used together to set up encrypted connections between devices. It helps keep data sent over public networks secure. IPsec is often used to set up VPNs, and it works by encrypting IP packets, along with authenticating the source where the packets come from.

Within the term “IPsec,” “IP” stands for “Internet Protocol” and “sec” for “secure.” The Internet Protocol is the main routing protocol used on the Internet; it designates where data will go using IP addresses. IPsec is secure because it adds encryption* and authentication to this process.
