This document is only a brief synopsis of the ever-expanding and demanding field of information security. It contains explanations, screenshots or visual cues, and tips on multiple subjects such as system defenses, reducing vulnerabilities, and the presence of malicious threats. Smaller areas, such as vulnerability assessment and penetration testing, are also covered because they are very significant in the security of information. While vulnerability assessment is a necessity, penetration testing is purely an option to the security engineer.
What is Information Security ?
Information security is often defined as the security or assurance of information and it requires the ability to maintain the authenticity of the information. The three common components of information security are confidentiality, integrity, and availability and they form an essential base for the overall picture of information security. Confidentiality is perhaps one of the most common aspects of information security because any information that is withheld from the public within the intentions to only allow access to authorized individuals is confidential. Encryption is often used to maintain the confidentiality of information as encryption is one of multiple methods of access control and Microsoft BitLocker is an example of access control-encryption feature. Although TrueCrypt is no longer a secure method of protecting data, I will discuss it further in the
Data confidentiality is one of the three main IT security components which are data confidentiality, integrity, and availability (CIA). To keep your data confidential means to protect your data from unauthorized access. In other words, sensitive data are stored in a protected system that keep these information and data away from attackers and here the data confidentiality will measure the ability of the system to protect its data.
An effective information security program should include, periodic assessments of risk, including the magnitude of harm that could result from the unauthorized access, use, disclosure, disruption, modification, or destruction of information and information systems that support the operations and assets of the organization. Policies and procedures should be based on risk assessments, cost effective reduced information security risk, and it should ensure that the information security is addressed throughout the entire life cycle of each and every organizational information system. Subordinate plans for providing sufficient information security for groups of the information system, facilities, networks, or information systems.
Data can be characterized as helpful information for an examination, choice or undertaking. Data should dependably, be ensured legitimately, paying little respect to how it is put away, introduced, or imparted. The fundamental points of data security are to protect:
Information Security and the breaches are the major concerns for any organization. Maintaining the data safely against the unauthorized access, data loss and modification of data is very important. Because any organization runs on the credibility of the customers.
Data security is not just imperative to consumers whose information is stored; it is also significant to the organizations who store this information. A failure to secure information can impede a business in a number of ways. Losing information that gives an organization a competitive advantage can lead the destruction of; and cause consumers to abandon the organization and seek out another organization to do business with.
Information security involves the protection of information regardless of whether it is in digital form, being stored on computers, or in transit over a network. It is a set of strategies for managing the processes, tools, and policies necessary to prevent and detect threats to
Also the information systems where the data or information is stored have to be protected from unauthorised access, use or disclosure. Also one needs to be careful not to disrupt the system, modify or destruct data or information as they are highly sensitive and cause disastrous effects for the organisation and the individual related to it. These type of data are confidential and used my governments, hospitals, military and other highly sensitive secure organisations. Information security is a business requirement and also a legal requirement.
With that being said, the focus of the paper will divert from the whole and focus on a specific protection, Confidentiality. Confidentiality is an important concept at the tip of the CIA Triad. The question becomes, how do business, organizations, and individuals protect their information and “ensure that only authorized parties can view information” (Ciampa, 2012, p.12)? A significant characteristic of ensuring confidentiality revolves around the concepts of cryptography and encryption. These two terms are not interchangeable. Encryption is a form of cryptography; while cryptography is “the science of secret communication, encryption refers to one component of that science” (Forlanda, 2015). More specifically, encryption is a practice that uses a mathematical algorithm to create a secure and secret message that can only be read by select individuals who are given access, in the form of a key, to decrypt and decipher the information. Encryption works by taking unaltered data that is ready to be encrypted, also known as plaintext data, and placing that data through an encryption algorithm that converts the text into scrambled data, otherwise known as ciphertext. Based on the mathematical algorithm used to scramble the data, a key is used to decrypt the data based on a decryption
Any time a new security system is implemented it needs to be tested thoroughly. Part of the tests that are performed to ensure that the new or prosed system meets the goals set forth by the organization, is penetration testing. Penetration testing involves security professionals simulating “attacks by a malicious external source” (Whitman & Mattord, 2012, p. 551). These tests allow the security professionals to determine points of failure that may not have been identified in vulnerability testing, as well as the criticality of the items defined in the vulnerability tests. These tests can be performed in one of two ways, either with or without knowledge of the organizations information technology infrastructure. These two tests are known
The confidentiality of the information is one of the most important element in the transaction security. It can be defined as the protection of a user’s information, personal and financial, from other parties than the recipient.
Introduction:- in, business or in any sector relating trading, banking etc., information security is an important factor in which it is necessary to secure or hide the important business details such as client detail etc. So in information system technology, data storage management should be extremely secure & the security conditions or security policies would be hard and there should be no flaw or weakness in information security system. Although, no computer system is 100% efficient to stop security flaws but the effectiveness of the information system should be so high so that it would be very hard for a person or intruder to hack the security management of the information system. In information systems risk can be physical e.g.: from an employee which work in the organization and logical e.g. from an intruder that can remotely access the system from outside without permission.
Answer: Information Security is the practice of defending (guiding) information by considering the CIA Triad Principles which are Confidentiality (Authorize access), Integrity (Accuracy and Completeness) and Availability.
Computer security has been creating issues in the news lately. Almost every week, corrupt forces try to take down high-profile websites. Companies lose millions of dollars and suffer damage to computer systems. As a result, large companies spend thousands of dollars on security systems and products to protect the doors to their corporate networks.
Present era is a “technological era”. Technological revolution is an inevitable concept that has brought drastic changes in the concept of communication, networking, IT etc. Information technology is growing at an alarming rate day by day. Corporate sectors, businesses tend to use complex technological and network environments. MANET is one such variant for technological revolution which is in a strong pace to gain popularity as they provide wireless connectivity irrespective of their geographic position. Apart from this there are numerous other privileges provided by this adhoc networking that has acted as a boon in the field of networking.
