Remote Authentication Dial-In User Service defines the meaning of the term RADIUS. It is a networking protocol that assists client servers. It is a UDP-based protocol that mainly utilizes a mysterious secret to verify the user's activities. 802.1 X wi-fi authentication is a verification protocol that authenticates the user's identity whenever they try to access the network resources for working purposes. The user identity is directly linked to the Radius Server. The term Freeradius was discovered in June 1999 by two personalities, Miquel van  Smoorenburg and Alan Dekok. More than 100 million people use freeradius to access the internet daily. It has been discovered that Freeradius is responsible for verifying approx. 1/3 of the users on the internet. By cross-referencing the user's credentials with a database, the RADIUS server validates their identity. The Radius Server   receives the credentials from the RADIUS client and checks them against an authentication database t...

A database that is designed specifically for reading, browsing, and searching is called a directory. Directories frequently offer advanced filtering options and comprehensive, attribute-based information. The elaborate transaction or roll-back techniques used in database management systems built to handle high-volume, complex modifications are typically not supported by directories. If directory modifications are permitted, they are often straightforward all-or-nothing changes.  Directories are configured to respond quickly to frequent lookup or search activities. They could be able to extensively reproduce information to improve availability and dependability and shorten reaction times. Temporary discrepancies between duplicacy of directory information may be acceptable if they finally synchronize. To access information centrally stored via a network, utilize the lightweight client-server protocol known as LDAP . Unfortunately, an operating model for a directory service cannot be ...

Cybersecurity is one of the most important issues in today's world. It has become a global concern with frequent, sophisticated, and costly cyberattacks. The focus was at an all-time high because there were many attacks with increased costs which made them more harmful than before. Such situations happened due to the pandemic forcing people to work remotely, making organizations implement Zero Trust architectures, reducing chances for breaches whenever implementing these technologies. The Zero Trust Model can be simply explained. It's not one technology or solution but rather an approach on which you must build your security ecosystem for the most part; however it does have some strategies in place such as assumption of harm ( assume evil ), filtering traffic through sensors that detect malicious code before allowing access to devices protected by these technologies - this helps protect against outside threats like phishing emails sent from legitimate accounts belonging to cow...

Role based access control (RBAC) is a way to restrict network traffic based on individual users' roles within an enterprise. Users are given only the permissions necessary for them, ensuring employees can't view or edit sensitive information unless it pertains specifically to their job description while also preventing low-level staff from accessing high-up stuff! Working of Role Based Access Control RBAC is a system that naturally fits into companies who want to analyze their security needs and job duties.  Employees are grouped into roles according to the function within an organization, with access permissions aligned accordingly for users of similar functions performing identical tasks, such as accountants or insurance agents. It's also useful if you have many people doing very similar jobs like customer service representatives. Every employee will need some level of permission on certain types of files (though not all) because they're responsible for certain portf...

When it comes to information security, identity and access management are vital. IAM provides an interface that ties into the organization's governance policies for managing user accounts, with different levels of privilege misuse being one prevalent threat actor in most ransomware attacks today. It provides the framework to manage users' Identity Lifecycle, but what are some other benefits? IAM helps organizations adopt an appropriate level for each person within its walls - whether they're privileged or not!  Identity and access management describes various protection mechanisms to prevent unauthorized access. IAM uses different types of controls, these controls can be implemented in several ways, and the effectiveness depends on how seriously you take your data regulations. Let's have a look at some of these control systems. 1. Mandatory Access Control: This system enforces strict rules for what employees are allowed to see when it comes down to their clearance lev...

RBAC or Role Based Access Control is a network security system  designed to restrict system access depending on the designation/ role of a person in an organization.  The working mechanism of RBAC involves setting permissions and privileges, which defines the user access to the systems and automatically restricts it. The main idea behind using role based access control is to safeguard sensitive and crucial information. When using RBAC, the leading authorities of an organization assign each working employee a role and determine their position in the functional space, hence deciding how much data access needs to be provided to them. However, this security system is mostly used in big institutions.   Depending on a role one has occupied in the RBAC, one can read, edit, or delete articles in a writing application. Role-based access control has two roles, namely: Writer: A writer has the right to edit, delete and read.  Reader: A reader can only read the documents....

In the digital era, with everybody in need of wifi access all the time, the market to be connected with a secure internet system has increased more than ever. And, so in order to secure one’s data while using public wifi, it is always suggested and advised to use VPN. VPN stands for virtual private network, and it is a network security system that encrypts your data and hides your IP address by simply misguiding the location of a person using the data. Hence, securing your online identity. These days  VPN for business is not just the only use left of it, but commoners have too started using VPN for their own purposes. Let’s have a look at some of the reasons why one should use a VPN. 1. Security on public wifi There’s no doubt that public and open wifi are easy and very convenient to use, but at the same time, they are a risk to one’s data.  Anyone who is using open wifi is at higher risk of data breaches and ensuring you don’t encounter any such unfortunate event, VPN is adv...

Lightweight Directory Access Protocol, or we can refer to it as LDAP , is a security software system that is designed to store and arrange the data to make it easily searchable.  Sort of information that can be stored by LDAP is - 1) Information about organizations 2) Devices 3) Users stored in directories Servers mainly use LDAP to speak with on-premise directories. The information stored in an LDAP system is framed in a hierarchical structure, and it is known as Directory Information Tree (DIT). All the organizing, and structuring of data, which make it easier to navigate directories, find specific data, and administer user access policies is done by DIT.  LDAP functions to serve as the central hub, or we can source for authentication and authorization. Apart from data and information, LDAP also stores user credentials (username/password) and then accesses them later to authenticate the user. LDAP is based and functions on a client-server interaction.  Let us talk abou...

The main difference between an LDAP server and an Active Directory is that one of them, i.e Active directory has a much more complex network to operate compared to, though both are used to secure and safeguard the network. LDAP does not come with any complexities and functionalities like an active directory.  Let’s have a detailed look at both LDAP and active directory. LDAP LDAP is an abbreviation for Lightweight Directory Access Protocol. An LDAP server is a lightweight cross-platform software protocol that is used for directory service authentication.  LDAP is one of those security network systems that allow anyone to communicate with the directory service providers. It also allows locating data related to the organization, users, devices, and other resources such as files in a network.  Directory services are a storehouse of user account details, including username, password, and computer account; hence, LDAP acts as a common central place for authentication in such...
