Let us understand what hashing is.HashingHashing is a numerical operation that modifies data into a specific number created from a string of text. The output is referred to as message digest or hash. It is possible to implement hashing on any element of data. The input data can have an arbitrary length but the output is always constant.In hashing, data goes through the hashing algorithm and supports a unique output but it is not possible to modify it back to the original information. A unique element of data will always make the same hash. Hashing is simpler to implement, but ... Read More

Let us understand what the solution architecture is.Solution ArchitectureSolution architecture (SA) is an architectural representation of a particular solution. Solution architecture associates direction from different enterprise architecture viewpoints (business, data, and technical), and enterprise solution architecture (ESA).A solutions architect is important for computing an organization’s business requirements and deciding how IT can provide those needs leveraging software, hardware, or infrastructure. Aligning the IT method with business goals has become superior, and a solutions architect can help regulate, develop, and execute technical solutions in support of business goals.A solutions architect also traverses communication between IT and business services. This architect is ... Read More

Let us understand what penetration testing is.Penetration TestingPenetration testing is a security which is applied where a cyber-security expert tries to discover and handle vulnerabilities in a computer system. Penetration testing is carried out to powerful an enterprise's security framework to defend its IT base from potential cyber-attacks.The tests work to identify any weakness, malicious content, errors, and vulnerabilities in the system. Penetration testing is an element of ethical hacking, where the main objective is to penetrate the data system.Penetration Testing is a legal, structured procedure to compute the security posture of an organization. This practice simulates an attack against ... Read More

Let us begin by understanding what DWDM is.DWDMDWDM represents Dense Wavelength Division Multiplexing. It is a technology in which several optical signals (laser light) of multiple wavelengths or colors are combined into one signal and are sent over the connecting channel to a lengthy area.When the optical signal transmission distance changes into thousands of kilometers, it results in loss of few signals. It can satisfy this signal loss, optical fibre amplifiers are used in the DWDM transmission system.The DWDM technology requires this gain bandwidth to send multiple optical signals together effectively. DWDM can address up to 80 channels (80 optical ... Read More

Let us begin by understanding what software security is.Software SecuritySoftware security is produced to protect and secure servers, computers, cellular devices, and networks from unauthorized access, intrusions, viruses, and several threats. Software security can defend information, users, systems, and organization from a broad range of risks.Software systems can be linked to stealing information, monitor content, enter vulnerabilities, and damage the behavior of the application. Malware can generate DOS (denial of service) or crash the framework itself. Buffer overflow, stack overflow, command injection, and SQL injections are the most common attacks on the software.Software security can represent the software that is ... Read More

Let us begin by learning about encryption.EncryptionEncryption can scramble the information so that only authorized persons can unscramble the conversation records. Encryption operates by encoding the original data or plaintext with the support of sophisticated algorithms that transform it to unreadable text or ciphertext.A decryption key would be required to revert to a readable structure. Encryption is best adapted for unstructured fields or databases that are not transformed regularly or saved in multiple systems. It can be used to protect sensitive information including payment card information (PCI), personally identifiable information (PII), financial account numbers, etc.Types of EncryptionThere are two types ...

Let us begin by learning about keyloggers.KeyloggerA keylogger is a technology that tracks and data consecutive keystrokes on a keyboard. Because sensitive data including usernames and passwords are often introduced on a keyboard, a keylogger can be a very fatal technology.There are several types of keyloggers based on diverse keylogging methods. These contain hardware and software keyloggers. Software keyloggers can be constructed into rootkits or other less detectable forms and can infiltrate a computer in various methods.Hardware keyloggers can be appropriated into the line from a keyboard to a device. There are different, more obscure structures of keyloggers that depend ... Read More

Let us begin by learning about tokenization.TokenizationTokenization is the phase of restoring sensitive data components (including a bank account number/credit card number) with a non-sensitive substitute, referred to as a token.Unlike encrypted data, tokenized information is illegible and irreversible because there is no numerical relationship between the token and its original number. No key or algorithm that can be used to change the original information for a token. Rather than, tokenization uses a database, referred to as a token vault, which stores the relationship among the sensitive value and the token. The actual data in the vault is then secured, ...

Firstly, let us understand what cryptography is.CryptographyCryptography is the technique of sending secured data and connections via some programs so that only the destined person understands the actual records that is shared. This mode of process intercepts unauthorized accessibility for the information.Encoding of data in cryptography follows numerical hypotheses and few computations defined as algorithms. The encoded information is transmitted so that it makes it difficult to find the original information. These sets of rules are used in the process of digital signing, authentication to secure information, cryptographic key development, and safeguard all your financial transactions.Types of CryptographyThere are various ...

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 ...
