Application Gateway is a type of firewall that supports application-level control over network traffic. Application gateways can be used to deny access to the resources of private networks to distrusted clients over the web.An application gateway is an application program that runs on a firewall system between two networks. When a client program creates a link to a destination service, it connects to an application gateway, or proxy. The client then compromise with the proxy server to interact with the destination service. In effect, the proxy creates the connection with the destination behind the firewall and acts on behalf of ... Read More
Application-level GatewayAn application gateway or application level gateway (ALG) is a firewall proxy which offers network security. It filters incoming node traffic to certain specifications which define that only transmitted network application information is filtered. Such network applications such as File Transfer Protocol (FTP), Telnet, Real Time Streaming Protocol (RTSP) and BitTorrent.An application layer gateway also known as an application proxy gateway. It can perform a several functions at the application layer of an infrastructure, generally known as layer 7 in the OSI model. These functions can include address and port translation, resource allocation, software response control, and synchronization of ... Read More
strings.IndexAny is a built-in function in Golang which is used to get the index of the first instance of any Unicode code point from the input substring. If the substring is found, it returns the position starting from 0; else it returns -1.Syntaxfunc IndexAny(s, chars string) intWhere, s – The original given string.chars – It is the substring that is to be checked in the given string.Example 1Take a look at the following example.package main import ( "fmt" "strings" ) func main() { // Defining the Variables var str string var charstring string var ...

A firewall can be represented as a special type of network security device or a software program that monitors and filters incoming and outgoing network traffic based on a represented group of security rules. It facilitate as a barrier between internal private networks and external sources (including the public Internet).The objective of a firewall is to enable non-threatening traffic and prevent malicious or unwanted data traffic for securing the computer from viruses and attacks. A firewall is a cybersecurity tool that filters network traffic and provide users block malicious application from accessing the web in infected computers.Firewalls can be executed ... Read More
Strings.Index is a built-in function in Golang that returns the index of the first instance of a substring in a given string. If the substring is not available in the given string, then it returns -1.SyntaxThe syntax of Index() is as follows −func Index(s, substring string) intWhere, s – Original given stringsubstring – It is the string whose Index value we need to findExample 1Let us consider the following example −package main import ( "fmt" "strings" ) // Main function func main() { // Initializing the Strings x := "Learn Golang on Tutorialspoint" ...

Asymmetric cryptography is a second form of cryptography. It is called a Public-key cryptography. There are two different keys including one key is used for encryption and only the other corresponding key should be used for decryption. There is no other key can decrypt the message and not even the initial key used for encryption. The style of the design is that every communicating party needs only a key pair for communicating with any number of other communicating parties.Asymmetric cryptography is scalable for use in high and ever expanding environments where data are generally exchanged between different communication partners. Asymmetric ... Read More
Golang has a built-in string function called Compare() that we can use to compare two strings. Here strings are compared using the lexicographical order.Syntaxfunc Compare(a, b string) intReturn TypesIf the strings (a == b), it returns 0.If the strings (a > b), then it returns 1If the strings (a < b), then it returns -1ExampleLet us consider the following example −package main // importing fmt and strings import ( "fmt" "strings" ) func main() { // Intializing the variables var a1 = "a" var a2 = "b" var a3 = "welcome" var a4 ...

RBAC stands for Role-based access control. It also known as role-based security. It is an access control method that creates permissions to end-users depends on their role within the organization. RBAC supports fine-grained control, providing a simple, controllable method to access administration that is less error-prone than individually assigning permissions.Role-based access control (RBAC) is the notion of securely managing access by creating and restricting user access depends on clearly established roles. Organizations rely on RBAC to put solid, pre-defined, and pre-approved access policies in place that recognize which access privileges each user required and which access to grant or delete.Roles ...

RBAC stands for Role-based access control. It also known as role-based security. It is an access control method that creates permissions to end-users depends on their role within the organization. RBAC supports fine-grained control, providing a simple, controllable method to access administration that is less error-prone than individually assigning permissions.This can decrease cybersecurity risk, protect sensitive information, and provides that employees can only access information and perform actions they required to do their jobs. This is referred to as principle of least privilege.Roles are based on multiple elements in RBAC, such as authorization, responsibility, and job specialization. Organizations generally designate ...

There are several types of memory card which are as follows −SD Card − It is the most common types of memory cards, and it stands for Secure Digital card that is designed to support high-capacity memory in a small size. Mainly, it is used in several small portable devices including handheld computers, digital video camcorders, digital cameras, mobile phones, etc.Approximately, more than 8000 multiple models and over 400 brands of electronic equipment use SD technology. It measures 32 x 24 x 2.1 mm and weighs approximately 2 grams and is treated a standard for the industry because of widespread ... Read More
