Computer security , cybersecurity or information technology security IT security is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware , software , or electronic data , as well as from the disruption or misdirection of the services they provide. The field is becoming increasingly significant due to the increased reliance on computer systems , the Internet [2] and wireless network standards such as Bluetooth and Wi-Fi , and due to the growth of "smart" devices , including smartphones , televisions , and the various devices that constitute the " Internet of things ". Owing to its complexity, both in terms of politics and technology, cybersecurity is also one of the major challenges in the contemporary world.

The history of cyber security began with a research project. A man named Bob Thomas realized that it was possible for a computer program to move across a network, leaving a small trail wherever it went. A man named Ray Tomlinson yes, the same guy who invented email saw this idea and liked it. He tinkered with the program and made it self-replicating—the first computer worm.

An information system can be defined as a set of interrelated components that collect, manipulate, store data, distribute information to support decision making and provide a feedback mechanism to monitor performance. It may also help the manager and workers to analyse problems, visualize complex subject, and create new products.

Software, Hardware, information system users, computer system connections and information, and the system's housing are all part of an Information System. People: Peoples are the most essential part of the information system because without them the system cannot be operated correctly.

Hardware: It is the part of a physical component of an information system which we can touch. The information system hardware includes the computer, processors, monitors, printer, keyboards, disk drives, iPads, flash drives, etc. Software: It is a set of instruction that tells the hardware what to do. It can be used to organize, process and analyse data in the information system. Data: Data is a collection of facts. Information systems work with data. These data can be aggregated, indexed, and organized into tables and files together to form a database.

These databases can become a powerful tool for every businesses information system. Network: It includes internet, intranet, extranet to provide successful operations for all types of organizations and computer-based information system. Procedures: It specifies the policies that govern the operation of an information system.

It describes how specific method of data are processed and analysed to get the answers for which the information system is designed. Feedback: It is the component of an information system which defines that an IS may be provided with feedback. It is a strategic-level information system which is found at the top of the Pyramid.

Its primary goal is to provide information gathered from both internal and external sources to the senior executives and management to analyse the environment in which the organization operates, and to plan appropriate courses of action for identifying the long-term trends. It can also be used to monitor organization performance as well as to identify opportunities and problems. EIS is designed in such a way that it can be operated directly by executives without the need for intermediaries.

A DSS or Decision Support System is a computer application program used by senior managers to analyse the business data and presents it in that form in which the users can make business decisions more easily. These systems are usually interactive and can be used to solve ill-structured problems in an organization. It helps in exchanging the information within the organization. MIS or Management Information System is the use of information technology, people, and business processes to record, store, manipulate, and process data to produce meaningful information.

These information helps decision makers to make day to day decisions correctly and accurately. It is used to make a tactical decision middle-term decision to ensure the smooth running of an organization. It also helps to evaluate the organization's performance by comparing previous outputs with current output. TPS or transaction processing system is a type of information processing system for business transactions that involve the collection, storage, modification and retrieval of all data transaction of an enterprise.

The characteristics of a Transaction Processing System includes reliability, performance, and consistency. A TPS is also known as real-time processing. An Information System Development is a set of activities, methods, best practices, deliverables and automated tools that every organization use to develop and continuously improve information systems and its related software. The purpose of the first step is to find the scope of the problem and determine solutions.

This phase also includes and considered resources, time, cost, and other items for the requirements of the information system. The purpose of this steps is to find a path to the solution determined by system analysis. In this phase some solution require modification in the existing system, some solution does not require an information system, and some solution requires a new system.

The purpose of the third step is to evaluate the feasibility issues related to financial, technical, and organizational. It measures the time and cost to design an information system. It evaluates the business value of a system and finds the best solution for developing an information system.

The purpose of the last step is to create the detailed design specification for an information system. This phase provides complete implementations for-. JavaTpoint offers too many high quality services. Mail us on hr javatpoint. Please mail your requirement at hr javatpoint.

Components of Information System The components that must be combined together in order to produce an information system are: People: Peoples are the most essential part of the information system because without them the system cannot be operated correctly.

Types of Information system The information systems can be categorized into four types. These are: 1. Executive Information Systems It is a strategic-level information system which is found at the top of the Pyramid. The role of Executive Information Systems are: It is concerned for ease of use.

It supports unstructured decisions. It concerned with predicting the future. It is highly flexible. It is effective. It uses both internal and external data sources. It is used only at the higher levels of authority. Decision Support Systems A DSS or Decision Support System is a computer application program used by senior managers to analyse the business data and presents it in that form in which the users can make business decisions more easily.

The role of Decision Support System are: It supports ill-structured or semi-structured decisions. It is used by senior managerial levels. It is concerned with predicting the future. Management Information Systems MIS or Management Information System is the use of information technology, people, and business processes to record, store, manipulate, and process data to produce meaningful information.

The role of Management Information Systems are: It is based on internal information flows. It supports relatively structured decisions. It is inflexible and has a little analytical capacity. It is used by lower and middle managerial levels.

It deals with the past and presents rather than the future. Transaction Processing Systems TPS or transaction processing system is a type of information processing system for business transactions that involve the collection, storage, modification and retrieval of all data transaction of an enterprise.

The role of Transaction Processing System are: It produces the information for other systems. It is used by operational personnel plus supervisory levels. It is efficiency oriented. Development of Information System An Information System Development is a set of activities, methods, best practices, deliverables and automated tools that every organization use to develop and continuously improve information systems and its related software.

There are four steps which can be used to develop an information system. Define and understand the problems The purpose of the first step is to find the scope of the problem and determine solutions.

Develop an alternative solution The purpose of this steps is to find a path to the solution determined by system analysis.

Evaluate and choose the best solution The purpose of the third step is to evaluate the feasibility issues related to financial, technical, and organizational. Implement the solution The purpose of the last step is to create the detailed design specification for an information system. This phase provides complete implementations for- Hardware selection and acquisition Software development and programming Testing such as Unit, System, Acceptance testing Training and documentation Online practice, step-by-step instruction Conversion, i.

Secure Sockets Layer SSL is a protocol developed by Netscape for establishing an encrypted link between a web server and a browser. SSL is an industry standard which transmits private data securely over the Internet by encrypting it. It is used by many websites to protect the online transactions of their customers. Description: SSL functions around a cryptographic system which uses three keys t. Cross-site scripting XSS is a type of computer security vulnerability. Description: Cross-site scripting XSS exploits the 'same-origin-policy' concept of web applications to allow hackers to extract information from the system.

It represents a broad consensus about the most critical security risks to web applications. Globally recognized by developers as the first step towards more secure coding. Companies should adopt this document and start the process of ensuring that their web applications minimize these risks. Using the OWASP Top 10 is perhaps the most effective first step towards changing the software development culture within your organization into one that produces more secure code. Thanks to Aspect Security for sponsoring earlier versions. To collect the most comprehensive dataset related to identified application vulnerabilities to-date to enable analysis for the Top 10 and other future research as well.

It is a general principle that well-managed audit trails are key indicators of good internal business controls. Audit trails have transitioned from manual to automated electronic logs that make this historical information more accurate, readily accessible, and usable. Successful audit trails demand a top down commitment by upper management, affected departments, and IT personnel. This article will define an audit trail, what should be included, the importance of tracking this information, and how to best manage audit trail data. Audit trails are the manual or electronic records that chronologically catalog events or procedures to provide support documentation and history that is used to authenticate security and operational actions, or mitigate challenges.

A cyber security risk assessment is about understanding, managing, controlling and mitigating cyber risk across your organization. Together we can end cyber attacks at the endpoint, across the enterprise, to everywhere the battle moves. Address both individuals and organizations. Asset restriction AR That is primarily because, to qualify any cybersecurity interview, just searching for Ans: An article on cybersecurity analyst interview questions and answers is incomplete without having this question.
