Information security is a group of practices designed to perform data capture from unauthorized access and variation for the period of storing or broadcasting from one position to another.Information security is designed and required to secure the print, digital, and other private, susceptible, and personal information from unauthorized persons. It is generally used to secure information from being obsolete, recognition, destruction, modification, and disruption.Information security is the prevention and security of computer assets from unauthorized access, use, alteration, deterioration, destruction, and various threats.There are two main sub-types such as physical and logical. Physical information security includes tangible security devices. Logical ... Read More

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

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

Symmetric Key Cryptography In symmetric key cryptography, an individual key is used for both encryption and decryption. The sender needs the key to encrypt the plaintext and sends the cipher document to the receiver. The receiver used the similar key (or ruleset) to decrypt the message and recover the plaintext. Because an individual key is used for both functions, symmetric key cryptography is also known as symmetric encryption. Symmetric key cryptography schemes are usually categorized such as stream ciphers or block ciphers. Stream ciphers works on a single bit (byte or computer word) at a time and execute some form ...

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

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

Memory CardA memory card is a type of storage device that can store videos, photos, or other data files. It provide a volatile and non-volatile medium to save data from the inserted device. It is also defined as a flash memory. Generally, it is used in devices like phones, digital cameras, laptops, digital camcorders, game consoles, MP3 players, printers, etc.A memory card is generally used as a primary and portable flash memory in mobile phones, cameras and other portable and handheld devices. PC Cards (PCMCIA) were a predecessor of modern memory cards that were introduced for commercial goals. Besides supporting ... Read More
