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: 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: IT Compliance

IT compliance refers to businesses meeting all legal requirements, standards and regulations for the all the technology their company uses. Achieving these standards means following all industry regulations, government policies, security frameworks and customer terms of agreement to ensure the security and appropriate usage of software in business. In addition to protecting the security of businesses and customers, compliance standards promote the availability and reliability of services, and it ensures businesses use technology as per the industry standard

IT Simplified: Zero Trust

Zero Trust is a security framework requiring all users, whether in or outside the organization’s network, to be authenticated, authorized, and continuously validated for security configuration and posture before being granted or keeping access to applications and data. 

Execution of this framework combines advanced technologies such as risk based multi-factor authentication, identity protection, next-generation endpoint security, and robust cloud workload technology to verify a user or systems identity, consideration of access at that moment in time,  and the maintenance of system security. Zero Trust also requires consideration of encryption of data, securing email, and verifying the hygiene of assets and endpoints before they connect to applications.

IT Simplified: ISO 27001

What is ISO 27001?

ISO 27001 is the international standard that describes best practices for an Information Security Management Systems(ISMS). It’s based on a set of controls and measures, which organizations can use to achieve information security. 

The ISO 27001 standard requires that you have procedures in place to cover aspects of the ISMS, including:

Information security risk management (What are the risks you face and how do you treat those risks?)

Monitoring, measurement, analysis, and evaluation (How is the effectiveness of the information security management system evaluated?)

Improvement (How are nonconformities evaluated and corrected?)

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.

IT Simplified: Virtual Private Networks

VPNs or Virtual private networks are essential additions to organizational networks that allow companies of any size to easily and safely access their resources, whether they’re hosted locally or in the cloud. The primary purpose of an enterprise VPN is to fortify these sensitive assets and resources – which might include internal customer and sales systems, SaaS applications, and local file storage for employees who are now accessing them from many different devices and on unfamiliar (and potentially unsafe) Wi-Fi connections.

IT Simplified: Unified Endpoint Management

What is Unified Endpoint Management? 

Unified endpoint management is the method of centrally managing endpoint devices from a single location. These endpoints include mobile devices, desktops, laptops, tablets, wearables and other smart devices used for accessing networks or resources within an organization. 

With a UEM solution, organizations are able to unify the applications of data protection, device configuration, and usage policies. It provides a single view of users who use multiple devices and also helps in gathering workplace analytics regarding them. UEM also acts as the apex endpoint management solution in an organization by orchestrating related endpoint technologies such as identity services, client management tools, etc.
