describe the need for information security

(Pipkin, 2000), "...information security is a risk management discipline, whose job is to manage the cost of information risk to the business." Authorization to access information and other computing services begins with administrative policies and procedures. Most people have experienced software attacks of some sort. Without executing this step, the system could still be vulnerable to future security threats. (2008). Responsibilities: Employees' understanding of the roles and responsibilities they have as a critical factor in sustaining or endangering the security of information, and thereby the organization. [63], In this phase, the IRT works to isolate the areas that the breach took place to limit the scope of the security event. Building upon those, in 2004 the NIST's Engineering Principles for Information Technology Security[28] proposed 33 principles. These include:[60], An incident response plan is a group of policies that dictate an organizations reaction to a cyber attack. Older, less secure applications such as Telnet and File Transfer Protocol (FTP) are slowly being replaced with more secure applications such as Secure Shell (SSH) that use encrypted network communications. Attention should be made to two important points in these definitions. This requires that mechanisms be in place to control the access to protected information. The standard includes a very specific guide, the IT Baseline Protection Catalogs (also known as IT-Grundschutz Catalogs). The Drivers of the Information Security Business . Security tea… Top Information Security Threats. The first step in information classification is to identify a member of senior management as the owner of the particular information to be classified. According to Merriam-Webster Dictionary, security in general is the quality or state of being secure, that is, to be free from harm. It is worthwhile to note that a computer does not necessarily mean a home desktop. Furthermore, these processes have limitations as security breaches are generally rare and emerge in a specific context which may not be easily duplicated. [citation needed] The establishment of Transfer Control Protocol/Internetwork Protocol (TCP/IP) in the early 1980s enabled different types of computers to communicate. Use qualitative analysis or quantitative analysis. However, their claim may or may not be true. In 1998, Donn Parker proposed an alternative model for the classic CIA triad that he called the six atomic elements of information. The information must be protected while in motion and while at rest. Cloud computing security standards are needed before … [47] The reality of some risks may be disputed. The NIST Computer Security Division [46] U.S. Federal Sentencing Guidelines now make it possible to hold corporate officers liable for failing to exercise due care and due diligence in the management of their information systems.[57]. By the time of the First World War, multi-tier classification systems were used to communicate information to and from various fronts, which encouraged greater use of code making and breaking sections in diplomatic and military headquarters. The alleged sender could in return demonstrate that the digital signature algorithm is vulnerable or flawed, or allege or prove that his signing key has been compromised. Please write to us at contribute@geeksforgeeks.org to report any issue with the above content. Therefore, information security analysts need strong oral and written communication skills. Against that backdrop, highly personal and sensitive information such as social security numbers were recently stolen in the Equifax hack, affecting over 145 million people. [10] These issues include but are not limited to natural disasters, computer/server malfunction, and physical theft. The ISOC hosts the Requests for Comments (RFCs) which includes the Official Internet Protocol Standards and the RFC-2196 Site Security Handbook. In 1992 and revised in 2002, the OECD's Guidelines for the Security of Information Systems and Networks[30] proposed the nine generally accepted principles: awareness, responsibility, response, ethics, democracy, risk assessment, security design and implementation, security management, and reassessment. Confidentiality limits information access to authorized personnel, like having a pin or password to unlock your phone or computer. The Information Security Forum (ISF) is a global nonprofit organization of several hundred leading organizations in financial services, manufacturing, telecommunications, consumer goods, government, and other areas. And, [Due diligence are the] "continual activities that make sure the protection mechanisms are continually maintained and operational.". Here's a broad look at the policies, principles, and people used to protect data. Behaviors: Actual or intended activities and risk-taking actions of employees that have direct or indirect impact on information security. Get hold of all the important CS Theory concepts for SDE interviews with the CS Theory Course at a student-friendly price and become industry ready. It can be concluded from the discussion above that the fulfillment of the CIA principles and the compliance with the goal of information security is not a goal with a clear end but an open goal that continually changes with time and the development of technology, the means of information security and the emergence of new threats and vulnerabilities. The IT-Grundschutz approach is aligned with to the ISO/IEC 2700x family. develops standards, metrics, tests and validation programs as well as publishes standards and guidelines to increase secure IT planning, implementation, management and operation. [90] The BSI-Standard 100-2 IT-Grundschutz Methodology describes how information security management can be implemented and operated. Should confidential information about a business' customers or finances or new product line fall into the hands of a competitor or a black hat hacker, a business and its customers could suffer widespread, irreparable financial loss, as well as damage to the company's reputation. [70], Whereas BCM takes a broad approach to minimizing disaster-related risks by reducing both the probability and the severity of incidents, a disaster recovery plan (DRP) focuses specifically on resuming business operations as quickly as possible after a disaster. It’s important because government has a duty to protect service users’ data. The Enigma Machine, which was employed by the Germans to encrypt the data of warfare and was successfully decrypted by Alan Turing, can be regarded as a striking example of creating and using secured information. Communication: Ways employees communicate with each other, sense of belonging, support for security issues, and incident reporting. Retrieved from. Logical controls (also called technical controls) use software and data to monitor and control access to information and computing systems. Ensure the controls provide the required cost effective protection without discernible loss of productivity. Most security and protection systems emphasize certain hazards more than others. Access control is generally considered in three steps: identification, authentication, and authorization.[37]. This ensures the overall security of internal systems and critical internal data protection. The Institute of Information Security Professionals (IISP) is an independent, non-profit body governed by its members, with the principal objective of advancing the professionalism of information security practitioners and thereby the professionalism of the industry as a whole. The need to maintain information privacy is applicable to collected personal information, such as medical records, financial data, criminal records, political records, business related information or website data. Part of the change management process ensures that changes are not implemented at inopportune times when they may disrupt critical business processes or interfere with other changes being implemented. Clustering people is helpful to achieve it, Operative Planning: create a good security culture based on internal communication, management buy-in, security awareness and training programs, Implementation: should feature commitment of management, communication with organizational members, courses for all organizational members, and commitment of the employees, Post-evaluation: to better gauge the effectiveness of the prior steps and build on continuous improvement. In general, information security can be defined as the protection of data that owned by an organization or individual from threats and or risk. A newer version was passed in 1923 that extended to all matters of confidential or secret information for governance.[23]. Wired communications (such as ITU‑T G.hn) are secured using AES for encryption and X.1035 for authentication and key exchange. Some of the most common threats today are software attacks, theft of intellectual property, identity theft, theft of equipment or information, sabotage, and information extortion. (McDermott and Geer, 2001), "A well-informed sense of assurance that information risks and controls are in balance." Organizations have a responsibility with practicing duty of care when applying information security. According to Oxford Students Dictionary Advanced, in a more operational sense, security is also taken steps to ensure the security of the country, people, things of value, etc. This step is crucial to the ensure that future events are prevented. Recall the earlier discussion about administrative controls, logical controls, and physical controls. Typically the claim is in the form of a username. Information technology – Security techniques – Information security management systems – Overview and vocabulary. Information extortion consists of theft of a company's property or information as an attempt to receive a payment in exchange for returning the information or property back to its owner, as with ransomware. Its objective is to establish rules and measures to use against attacks over the Internet. (ISO/IEC 27000:2009), "The protection of information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction in order to provide confidentiality, integrity, and availability." It is important to note that there can be legal implications to a data breach. ISO is the world's largest developer of standards. A set of security goals, identified as a result of a threat analysis, should be revised periodically to ensure its adequacy and conformance with the evolving environment. The framework consists of a number of documents that clearly define the adopted policies, procedures, and processes by which your organisation abides. ... organizations must balance the need for security with users’ need to effectively access and use these resources. Controls can vary in nature, but fundamentally they are ways of protecting the confidentiality, integrity or availability of information. Identity theft is the attempt to act as someone else usually to obtain that person's personal information or to take advantage of their access to vital information through social engineering. This happens when employees' job duties change, employees are promoted to a new position, or employees are transferred to another department. In some cases, the risk can be transferred to another business by buying insurance or outsourcing to another business. Administrative controls form the framework for running the business and managing people. Describing more than simply how security aware employees are, information security culture is the ideas, customs, and social behaviors of an organization that impact information security in both positive and negative ways. "Preservation of confidentiality, integrity and availability of information. 2. Information security is information risk management. reduce/mitigate – implement safeguards and countermeasures to eliminate vulnerabilities or block threats, assign/transfer – place the cost of the threat onto another entity or organization such as purchasing insurance or outsourcing, accept – evaluate if the cost of the countermeasure outweighs the possible cost of loss due to the threat. The change management process is as follows[67]. Identifying information and related assets, plus potential threats, vulnerabilities and impacts; Deciding how to address or treat the risks i.e. ISO/IEC 27001 has defined controls in different areas. Organizations can implement additional controls according to requirement of the organization.
