describe the need for information security

The rapid growth and widespread use of electronic data processing and electronic business conducted through the internet, along with numerous occurrences of international terrorism, fueled the need for better methods of protecting the computers and the information they store, process and transmit. The ISOC hosts the Requests for Comments (RFCs) which includes the Official Internet Protocol Standards and the RFC-2196 Site Security Handbook. 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. Below is a partial listing of governmental laws and regulations in various parts of the world that have, had, or will have, a significant effect on data processing and information security. Research has shown that the most vulnerable point in most information systems is the human user, operator, designer, or other human. As of 2013[update] more than 80 percent of professionals had no change in employer or employment over a period of a year, and the number of professionals is projected to continuously grow more than 11 percent annually from 2014 to 2019.[13]. They also monitor and control access to and from such facilities and include doors, locks, heating and air conditioning, smoke and fire alarms, fire suppression systems, cameras, barricades, fencing, security guards, cable locks, etc. The availability of smaller, more powerful and less expensive computing equipment made electronic data processing within the reach of small business and the home user. It is part of information risk management. 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. ISO/IEC. One of management's many responsibilities is the management of risk. Cryptographic solutions need to be implemented using industry-accepted solutions that have undergone rigorous peer review by independent experts in cryptography. Authentication is the act of verifying a claim of identity. If the photo and name match the person, then the teller has authenticated that John Doe is who he claimed to be. [37], The terms "reasonable and prudent person," "due care" and "due diligence" have been used in the fields of finance, securities, and law for many years. [24] Procedures evolved to ensure documents were destroyed properly, and it was the failure to follow these procedures which led to some of the greatest intelligence coups of the war (e.g., the capture of U-570[24]). However, for the most part protection was achieved through the application of procedural handling controls. Cryptography provides information security with other useful applications as well, including improved authentication methods, message digests, digital signatures, non-repudiation, and encrypted network communications. (2008). 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. [47] The reality of some risks may be disputed. The foundation on which access control mechanisms are built start with identification and authentication. In 2011, The Open Group published the information security management standard O-ISM3. Attention should be made to two important points in these definitions. Information security analysts generally need to have previous experience in a related occupation. High availability systems aim to remain available at all times, preventing service disruptions due to power outages, hardware failures, and system upgrades. This means the computing systems used to store and process the information, the security controls used to protect it, and the communication channels used to access it must be functioning correctly. ACM. Information security professionals are very stable in their employment. Knowing local and federal laws is critical. A prudent person takes due care to ensure that everything necessary is done to operate the business by sound business principles and in a legal, ethical manner. 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. Information security is a set of practices intended to keep data secure from unauthorized access or alterations. Using strong antivirus software is one of the best ways of improving information security. An applications programmer should not also be the server administrator or the database administrator; these roles and responsibilities must be separated from one another. Without executing this step, the system could still be vulnerable to future security threats. Information security, sometimes shortened to infosec, is the practice of protecting information by mitigating information risks. Wireless communications can be encrypted using protocols such as WPA/WPA2 or the older (and less secure) WEP. However, debate continues about whether or not this CIA triad is sufficient to address rapidly changing technology and business requirements, with recommendations to consider expanding on the intersections between availability and confidentiality, as well as the relationship between security and privacy. With this approach, defense in depth can be conceptualized as three distinct layers or planes laid one on top of the other. For the individual, information security has a significant effect on privacy, which is viewed very differently in various cultures. Experience. The business environment is constantly changing and new threats and vulnerabilities emerge every day. Information security policy is a set of policies issued by an organization to ensure that all information technology users within the domain of the organization or its networks comply with rules and guidelines related to the security of the information stored digitally at any point in the network or within the organization's boundaries of authority. If it has been identified that a security breach has occurred the next step should be activated. For example, a lawyer may be included in the response plan to help navigate legal implications to a data breach. The basic principle of Information Security is: Attention reader! [18][19] Sensitive information was marked up to indicate that it should be protected and transported by trusted persons, guarded and stored in a secure environment or strong box. During this phase it is important to preserve information forensically so it can be analyzed later in the process. However, the implementation of any standards and guidance within an entity may have limited effect if a culture of continual improvement isn't adopted. develops standards, metrics, tests and validation programs as well as publishes standards and guidelines to increase secure IT planning, implementation, management and operation. Analysis of requirements, e.g., identifying critical business functions, dependencies and potential failure points, potential threats and hence incidents or risks of concern to the organization; Specification, e.g., maximum tolerable outage periods; recovery point objectives (maximum acceptable periods of data loss); Architecture and design, e.g., an appropriate combination of approaches including resilience (e.g. [25] These computers quickly became interconnected through the internet. It provides leadership in addressing issues that confront the future of the internet, and it is the organizational home for the groups responsible for internet infrastructure standards, including the Internet Engineering Task Force (IETF) and the Internet Architecture Board (IAB). The access control mechanism a system offers will be based upon one of three approaches to access control, or it may be derived from a combination of the three approaches.[37]. The policy should describe the different classification labels, define the criteria for information to be assigned a particular label, and list the required security controls for each classification. The International Organization for Standardization (ISO) is a consortium of national standards institutes from 157 countries, coordinated through a secretariat in Geneva, Switzerland. Calculate the impact that each threat would have on each asset. 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. The remaining risk is called "residual risk.". It also implies that one party of a transaction cannot deny having received a transaction, nor can the other party deny having sent a transaction.[40]. [38] This means that data cannot be modified in an unauthorized or undetected manner. For any information system to serve its purpose, the information must be available when it is needed. Creating a new user account or deploying a new desktop computer are examples of changes that do not generally require change management. 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. Change management is a tool for managing the risks introduced by changes to the information processing environment. One way that hackers gain access to secure information is through malware, which includes computer viruses, spyware, worms, and other programs. The sophistication of the access control mechanisms should be in parity with the value of the information being protected; the more sensitive or valuable the information the stronger the control mechanisms need to be. Most security and protection systems emphasize certain hazards more than others. After a person, program or computer has successfully been identified and authenticated then it must be determined what informational resources they are permitted to access and what actions they will be allowed to perform (run, view, create, delete, or change). Norms: Perceptions of security-related organizational conduct and practices that are informally deemed either normal or deviant by employees and their peers, e.g. We use cookies to ensure you have the best browsing experience on our website. Need-to-know helps to enforce the confidentiality-integrity-availability triad. A computer is any device with a processor and some memory. Using this information to further train admins is critical to the process. This stage could include the recovery of data, changing user access information, or updating firewall rules or policies to prevent a breach in the future. This can involve topics such as proxy configurations, outside web access, the ability to access shared drives and the ability to send emails. The three types of controls can be used to form the basis upon which to build a defense in depth strategy. IT security specialists are almost always found in any major enterprise/establishment due to the nature and value of the data within larger businesses. Disaster recovery planning includes establishing a planning group, performing risk assessment, establishing priorities, developing recovery strategies, preparing inventories and documentation of the plan, developing verification criteria and procedure, and lastly implementing the plan.[71]. Building upon those, in 2004 the NIST's Engineering Principles for Information Technology Security[28] proposed 33 principles. 72. [64], In this step information that has been gathered during this process is used to make future decisions on security. Cryptography is used in information security to protect information from unauthorized or accidental disclosure while the information is in transit (either electronically or physically) and while information is in storage.[37]. Internet security is a branch of computer security specifically related to not only Internet, often involving browser security and the World Wide Web [citation needed], but also network security as it applies to other applications or operating systems as a whole. The building up, layering on and overlapping of security measures is called "defense in depth."
