![]() Information security - Wikipedia. Information security, sometimes shortened to Info. Sec, is the practice of preventing unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction of information. It is a general term that can be used regardless of the form the data may take (e. The chief area of concern for the field of information security is the balanced protection of the Confidentiality, Integrity and Availability of data, also known as the CIA Triad, while maintaining a focus on efficient policy implementation and no major hampering of organization productivity. To standardize this discipline, academics and professionals collaborate and seek to set basic guidelines and policies on Password, Antivirus software, Firewall (computing), Encryption software, legal liability and user/administrator training standards. Overview[edit]IT security. Sometimes referred to as computer security, information technology security (IT security) is information security applied to technology (most often some form of computer system). It is worthwhile to note that a computer does not necessarily mean a home desktop. A computer is any device with a processor and some memory.Such devices can range from non- networked standalone devices as simple as calculators, to networked mobile computing devices such as smartphones and tablet computers.IT security specialists are almost always found in any major enterprise/establishment due to the nature and value of the data within larger businesses.They are responsible for keeping all of the technology within the company secure from malicious cyber attacks that often attempt to breach into critical private information or gain control of the internal systems.Information assurance. . The act of providing trust of the information, that the Confidentiality, Integrity and Availability (CIA) of the information are not violated, e.These issues include, but are not limited to: natural disasters, computer/server malfunction or physical theft. Since most information is stored on computers in our modern era, information assurance is typically dealt with by IT security specialists.A common method of providing information assurance is to have an off- site backup of the data in case one of the mentioned issues arise.

Threats[edit]Information security threats come in many different forms.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.Most people have experienced software attacks of some sort.Viruses,[4]worms, phishing attacks, and Trojan horses are a few common examples of software attacks.

The theft of intellectual property has also been an extensive issue for many businesses in the IT field. 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. Theft of equipment or information is becoming more prevalent today due to the fact that most devices today are mobile.[citation needed]Cell phones are prone to theft and have also become far more desirable as the amount of data capacity increases. Sabotage usually consists of the destruction of an organization′s website in an attempt to cause loss of confidence on the part of its customers. 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. There are many ways to help protect yourself from some of these attacks but one of the most functional precautions is user carefulness. Governments, military, corporations, financial institutions, hospitals and private businesses amass a great deal of confidential information about their employees, customers, products, research and financial status. Most of this information is now collected, processed and stored on electronic computers and transmitted across networks to other computers. 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. From a business perspective, information security must be balanced against cost; the Gordon- Loeb Model provides a mathematical economic approach for addressing this concern.[5]For the individual, information security has a significant effect on privacy, which is viewed very differently in various cultures. The field of information security has grown and evolved significantly in recent years. It offers many areas for specialization, including securing networks and allied infrastructure, securing applications and databases, security testing, information systems auditing, business continuity planning, electronic record discovery, and digital forensics.

History[edit]Since the early days of communication, diplomats and military commanders understood that it was necessary to provide some mechanism to protect the confidentiality of correspondence and to have some means of detecting tampering. Julius Caesar is credited with the invention of the Caesar cipher c. B. C., which was created in order to prevent his secret messages from being read should a message fall into the wrong hands, but for the most part protection was achieved through the application of procedural handling controls.[7][8] 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. As postal services expanded, governments created official organizations to intercept, decipher, read and reseal letters (e. UK Secret Office and Deciphering Branch in 1. In the mid- 1. 9th century more complex classification systems were developed to allow governments to manage their information according to the degree of sensitivity. The British Government codified this, to some extent, with the publication of the Official Secrets Act in 1. 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. In the United Kingdom this led to the creation of the Government Code and Cypher School in 1. Encoding became more sophisticated between the wars as machines were employed to scramble and unscramble information. The volume of information shared by the Allied countries during the Second World War necessitated formal alignment of classification systems and procedural controls. An arcane range of markings evolved to indicate who could handle documents (usually officers rather than men) and where they should be stored as increasingly complex safes and storage facilities were developed. The Enigma Machine which was employed by the Germans to encrypt the data of warfare and successfully decrypted by Alan Turing can be regarded as a striking example of creating and using secured information. 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. U- 5. 70). The end of the 2. 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. These computers quickly became interconnected through the Internet. 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.
