When it comes to preventing unauthorised access to, destruction of, or inspection of confidential data, information security has always been a major factor. Multimedia information is now used in every field throughout the world. The confidential information that is used in these areas must be kept secure. There are a variety of methods for keeping data secure. One of these is steganography, which is concealing information within other data into a format that the cover information remains unchanged. Cryptography, an encryption process that scrambles data into a written form that is sometimes referred to as a hash, is an auxiliary approach for securing information. Steganography and cryptography each have their own set of benefits and drawbacks. Even though both technologies give security, it is usually a good practise to combine Cryptographic algorithms to create additional layers of security. When cryptographic with steganography are combined, a multi-layer security paradigm is created. The proposed work's main goal is to add an additional layer of protection by using cryptography and steganography to encrypt and embed secret data conveyed across an insecure channel.

Using Data

Information security using data hiding in video provides high embedding capacity and security. Steganography is one of the oldest data protecting methodologies deals with the embedding of data. Video Steganography hides secret information file within a video. Present day communications are treated to be “un-trusted” in terms of security, i.e. they are relatively easy to be hacked. The proposed technique is invented to hide secret information into a video file keeping two considerations in mind which are size and security of the cover video file. At the sender side, the secret information which is to be hidden is encoded into cover video file. Double layered security for the secret data can be achieved by encrypting confidential information and by embedding confidential information into cover video file frames using encrypted embedding technique.

Information security is a huge trending topic in recent year. Many technique and algorithm were designed and developed toachieve the security of information and/or network across the world. Cryptography is one of the most common tools to provide suchsecurity. Nevertheless, steganography also provide a good security by hiding data within a media in a way that an attacker can't sensethe presence of the secret data. Compression don't normally imply any security , however , it messes up the original encoding of the dataand reduces its size by a measureable amount which makes it perfect for hiding .In this paper a system was proposed where a secretimage is compressed before encryption and hiding. JPEG algorithm was used for the compressing, while at the encryption stage RC4algorithm was used due to its fast processing speed. LSB (Least Significant Bit) technique then applied to hide the secret data within thecover image.

According to many business publications, firms that experience information security breaches suffer substantial reputational penalties. This paper examines incidents in which confidential information, for a firms customers or employees, is stolen from or lost by publicly traded companies. Firms that experience such breaches suffer statistically significant losses in the market value of their equity. On the whole, the data indicate that these losses are of similar magnitudes to the direct costs. Thus, direct costs, and not reputational penalties, are the primary deterrents to information security breaches. Contrary to many published assertions, on average, firms that lose customer information do not suffer reputational penalties. However, when firms lose employee information, we find significant reputational penalties.

Achievements in the sphere of automatization and telecommunication are an essential component of transformation of the international peace and security system. This article presents, that consequences of changes are of a dual character. On the one hand, new technologies are becoming an important component of society modernization strategies in developing countries, on the other hand, they can be used for armament modernization or creation of new means of confrontation in modern international relations. APR countries face the most relevant issue of information technologies usage. The article deals with the process of discussion of new challenges and threats to international security, emerging as a result of development and large-scale implementation of information-communication technologies. Positions of states regarding the adoption of resolution in the sphere of international information security were studied through examples of Japan, India, and China. It is proved in the article, that information technologies have become an important component of the security system in the world. Technologies usage may lead to steady international development as well as to information arms race. That is why working out a common position on international information security issues is of crucial importance. It is within the framework of the UN, that different states of the world are given an opportunity to express their visions of the problem of international information security and work out common approaches to its solution. The article shows, that states’ positions have similar as well as different features. For instance, all states express concern regarding possible limitation of technology transfer for the establishment of a more controlled international political environment. But states’ positions have major differences as to mechanisms of information security provision. Thus, Japan and India strive to achieve a balanced system of international information security, which should at the same time have preventive mechanisms against the emergence of threats in the information and science and technology spheres and guarantee continuation of scientific-technological development, which is a crucial component of development and modernization strategies in many countries of the world. China came forward with position of strong regulation of international information security issues and suggested framing of corresponding regulations of the states’ conduct in the cyberspace.

Information Security Policy

The necessity of formation of an effective information security system of the enterprise is substantiated. It is emphasized that when designing an information policy, the firm must comply with the requirements of the current legislation, take into account the level of technical support, especially the regulation of employees' access to confidential information, etc. It is stated that the costs of organizing information security measures should be appropriate to its value. The article identifies major threats that could be breached by confidential information. The list of the main normative legal acts aimed at bringing to civil, administrative and criminal responsibility for illegal collection, disclosure and use of information constituting a trade secret. The main stages of building an information security policy are summarized, the most common types of information threats related to the use of modern computer technologies are described. The necessity of developing a domestic original accounting (management) program that could be used in the long term by the vast majority of Ukrainian enterprises is pointed out. There are three groups of tools that are applied in the theory and practice of information security of the enterprise (active, passive and combined), emphasizing the need for planning and continuous monitoring in real time of all important processes and conditions that affect data security. It is noted that even if the information security system is built taking into account all modern methods and means of protection, it does not guarantee one hundred percent protection of the information resources of the enterprise, but a well-designed information security policy allows to minimize the corresponding risks. Key words: information security, information policy, information security, confidential information, information threats, information and communication technologies, software.
