Let us begin by learning about cloud architecture.Cloud ArchitectureCloud Architecture is a combination of elements needed for a Cloud Computing service. A Cloud computing architecture includes multiple elements like a front-end platform, a back-end platform or servers, a network or internet service, and a cloud-based delivery service.Cloud computing allocates the file system that develops over multiple hard disks and machines. Data is not saved in one area only and in case one unit fails the other will take over necessarily. The user disk space is authorized on the distributed file system, while another important element is an algorithm for resource ... Read More
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 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
We can find all XML nodes with Rest Assured using the XMLPath. If the response is in XML format, we need to use the methods under the XMLPath. If the value of the node is an integer, we have to use the method getInt.If the value of the node is a string we have to use the method getString and if the values are in a list, we can obtain its value with the getList method. We shall first send a GET request via Postman on a mock API URL.Using Rest Assured, we shall validate its XML Response containing the ... Read More
We can execute the DELETE requests in Rest Assured. This is done with the help of the http DELETE method. It is responsible for deleting a server resource.Delete request can have a request or response body. The status codes available for a DELETE request are listed below −200 (OK)204 (if there is no content for the record that we want to delete)202 (Accepted, deletion is not a single operation).We shall first send a DELETE request via Postman on an endpoint − https://dummy.restapiexample.com/api/v1/delete/100Using Rest Assured, we shall check if the response body contains the string Successfully! Record has been deleted.ExampleCode Implementationimport ... Read More
We can validate JSON schema in Rest Assured. The schema validation ensures that the Response obtained from a request satisfies a set of pre-built rules and the JSON body in the Response has a specific format.We shall use the method matchesJsonSchema (part of the JSONSchemaValidator class) for verifying the schema. To work with JSON schema validation we have to add the additional JSON Schema Validator dependency in the pom.xml in our Maven project −https://mvnrepository.com/artifact/io.rest-assured/json-schema-validatorWe shall first send a GET request via Postman on an endpoint: https://jsonplaceholder.typicode.com/posts/2 and observe its Response.Generally, a scheme for JSON Response is provided by a developer. ...
