To begin with, let us understand what hardware encryption is.Hardware EncryptionHardware Encryption uses hardware tools to encrypt information. A separate processor is dedicated to the function of authentication and encryption and is provided with a random number generator.Hardware encryption is self-contained within the device itself and doesn’t need any extra software. This can be established on external hard drives or solid-state drives called Self-Encrypting Drives (SEDs), and on smartphones; Apple’s Touch ID and ace ID are examples of hardware encryption.Advantages of Hardware EncryptionThe advantages of hardware encryption are as follows −The encryption process is separate from the host device and ...

A device that can bridge multiple network structures is known as a gateway. Therefore gateways can connect two dissimilar LANs. The major difference between gateways and routers is that routers work at the OSI model’s network layer. In contrast, gateways work from the lowest to the topmost layer, i.e., the application layer to the OSI model’s network layer.Gateways and routers are used correspondingly. It can transform data packets from one protocol architecture to another before forwarding them to connect two multiple networks. Therefore it includes protocol conversion services at the application layer. A gateway is a connecting device that can ... Read More
Let us understand what GSM is.GSMGSM represents Global Systems for Mobile Communications. It is the fundamental standard-bearer of 2G technologies. It is generally used in mobile communication. Short Messaging System (SMS) was introduced into GSM networks along with the capability to download content from multiple service providers. The content can ringtone, logos, and image messages. It can provide Voice telephony and data however the data cost is only 9.6Kb/s that is a very low bit cost for date communication.GPRSGPRS represents General Packet Radio Service. It can be used to provide higher information speed over GSM. It is not the restoration ... Read More
Data Communication is a phase of swapping data or information. This process contains a communication system that is created from hardware and software. The hardware part contains the sender and receiver devices and the intermediate devices through which the data moves. The software element includes specific rules which determine what is to be connected, how it is to be connected, and when. It is also referred to as a Protocol.The primary standards organizations for data communication are as follows −International Standard Organization (ISO)ISO is the international organization for standardization on a broad range of subjects. It includes mainly members from ... Read More
Antivirus software is a program that operates against virus protection. It can find or perceive the virus, and afterward, subsequent to discovering the nearness of the virus, it operates on expelling it from the computer system. Antivirus software operates as a prophylactic with the objective that it takes out a virus and keeps any potential virus from infecting your computer in the future.Antivirus software is one of the important levels of our internet security, be it on our PC or mobile devices. It is becoming important to have trustworthy protection on our smartphones, because it can do so much through ... Read More
Hacking is the art of examining the private things that are being private from general usage and discovering loopholes in the security and facilitating them to benefit others. Hacking is the procedure of discovering vulnerabilities in a system and using these found vulnerabilities to boost unauthorized access into the system to implement malicious activities ranging from eliminating system files to stealing sensitive data.Types of HackingThe types of hacking are as follows −Network Hacking − Network hacking defines gathering data about a network with the determination to harm the network system and hamper its services using multiple tools such as Telnet, ...

Simplified Data Encryption Standard (S-DES) is equivalent to the DES algorithm. The SDES encryption algorithm produces an 8-bit block of plaintext (example: 10111101) and a 10-bit key as input and makes an 8-bit block of ciphertext as output. The S-DES decryption algorithm takes an 8-bit block of ciphertext and the same 10-bit key can develop that ciphertext as input and makes the initial 8-bit block of plaintext.These algorithms generate a key and thus encapsulate the message with this key. There are two types of encryptions: asymmetric and symmetric, which are in vogue.Presentation LayerThe presentation layer in S-DES manages the translation, ... Read More
Cyber Security defines the technologies, procedures, and practices created to protect networks, devices, apps, and data from any type of cyber-attacks. Cyber security can be defined as information technology (IT) security.Cyber Security is all about preserving your devices and network from unauthorized access or alteration. The internet is not only the essential source of data, but it is also a channel through which people do business.The goal of cyber security is to protect computers, networks, and software programs from such cyber attacks. Most of these digital attacks are aimed at assessing, altering, or removing sensitive data; extracting money from victims; ... Read More
Let us begin by understanding what SNAT is.SNATSNAT represents Source NAT. Source NAT is used when an internal user starts a connection with an external Host. Therefore, the layer 3 device on which we already configured NAT, interprets the private IP address of the Host to Public IP. It can also interpret the source port in the TCP or UDP protocol headers.It can create an outbound connection, an ephemeral port is used to support the destination with a port on which to communicate and keep a distinct traffic stream. When these ephemeral ports are used for SNAT, they are known ... Read More
In Cloud Computing, Virtualization is creating a virtual platform of server operating framework and storage devices. This will support the client by supporting various machines simultaneously. It also enables sharing an individual physical example of a resource or an application to several clients.Cloud Virtualizations also handles the workload by changing traditional evaluation and developing it more scalable, economical, and adequate. Virtualizations in Cloud Computing promptly link the essential method of computing. The feature of virtualization is that it enables the distribution of applications to several clients and companies.Cloud Computing can also be referred to as services and applications delivered to ...
