Nowadays we are witnessing a total convergence towards a digital world where information is digitized, conveyed and processed using highly developed techniques and tools. The development of broadband networks, including the internet, has made easy the manipulation, transmission and sharing of information. However, new security issues arise and they are particularly related to integrity, confidentiality and traceability of data. Facing this situation, network security has become very important and challenges related to the protection of exchanged data over the internet against unauthorized access and use have increased. In the current work, we propose to implement an optimized steganography technique over TCP/IP protocol [1]. We have also tested it against well-known security equipment using latest versions. We will see that they are inefficient to stop this kind of cover channels. Our work is like an alarm to every IT administrator to change their thinking about data lost prevention (DLP) and exfiltration of sensitive information.

Security Problem

With the “Internet +” era of arrival, the major colleges and universities are in the construction of the wisdom of the campus, students and teachers living with the campus network is more and more closely related, Campus network security has become the protection of the wisdom of the campus construction. Campus network security issues become increasingly serious; a single security protection has been unable to meet the current security needs. This paper analyzes the major security threats facing the campus network, and presents the campus network security protection measures from the physical layer, network layer, system layer, application layer and management of five aspects, thus constructing the campus network's overall security defense system. The system has multiple security protection for Campus Network, thus improving the security of the campus network.

Blockchain-based technology is becoming increasingly popular and is now used to solve a wide range of tasks. And it's not all about cryptocurrencies. Even though it's based on secure technology, a blockchain needs protection as well. The risks of exploits, targeted attacks, or unauthorized access can be mitigated by the instant incident response and system recovery. Blockchain technology relies on a ledger to keep track of all financial transactions. Ordinarily, this kind of master ledger would be a glaring point of vulnerability. Another tenet of security is the chain itself. Configuration flaws, as well as insecure data storage and transfers, may cause leaks of sensitive information. This is even more dangerous when there are centralized components within the platform. In this chapter, the authors will demonstrate where the disadvantages of security and privacy in blockchain are currently and discuss how blockchain technology can improve these disadvantages and outlines the requirements for future solution.

Numerous organizations are using aspects of the cloud to store data, but as sensitive data is placed on the cloud, privacy and security become difficult to maintain. When users upload data to the cloud, they may become increasingly vulnerable to account hijacking, unauthorized access, and the data may become unavailable because of various technical reasons. Questions remain about the security of sensitive data in the cloud, and in this chapter, the authors perform an analysis of 36 peer reviewed publications describing 30 observations of cloud computing technology (2010-2017). In the articles, applications of cloud computing include, for instance, business (26%) and the internet of things (IoT; 2%), and the result suggests that some issues are unique to a particular domain (such as business, education, health) and some issues cross all domains. The results suggest that data integrity issues have the highest number of solutions whereas data breaches have the lowest number of solutions.

Malware (malicious software) is software designed to disrupt computer operation, gather sensitive information, or gain unauthorized access to a computer system. Most malwares propagate themselves throughout the Internet by self-relocation. Self-relocation is a built-in module in most malwares that gets the base address of the code to correctly infect the other programs. Since most legitimate computer programs do not need the self-relocate module, the detection of malware with self-relocation module can be viewed as a promising approach for malware detection. This paper presents a self-relocation based method for both known and previously unknown malwares. The experiments indicate that the proposed approach has better ability to detect known and unknown malwares than other methods.

In the process of implementing the Internet of Things, the object itself has identity information and identification equipment and encounters difficulties in communication security during the process of entering the network communication. Just like the Internet and wireless sensor networks, there are security issues in information transmission. Therefore, it is of great significance to study the mobile Internet of Things network security technology depression to protect the communication information in the mobile Internet of Things. This paper mainly studies the network security technology of intelligent information terminal based on mobile Internet of Things. This article will analyze and compare the mainstream encryption algorithms of the current mobile Internet and choose a safer and more secure HASH algorithm. We study the flow of key management, key generation, key distribution, verification key distribution, key update, key storage, key backup, and key validity time setting for mobile Internet of Things, using an existing identity cryptosystem. Based on encryption, the design technology of key management and authentication in this paper is improved. Compared with other methods, the storage consumption of this method on GWN is relatively medium. In the initial stage, the storage is 32 bytes, then in registration stage 1, it reaches 84 bytes, in registration stage 2, it is 82 bytes, and then, in the login authentication phase, the number of bytes rose and reached 356 bytes in authentication phase 3. Experimental results show that this protocol has certain advantages in ensuring safety performance.

This chapter describes how security is an important aspect in today's digital world. Every day technology grows with new advancements in various areas, especially in the development of web-based applications. All most all of the web applications are on the internet, hence there is a large probability of attacks on those applications and threads. This makes security necessary while developing any web application. Lots of techniques have been developed for mitigating and defending against threats to the web based applications over the internet. This chapter overviews the important region of web application security, by sequencing the current strategies into a major picture to further the future research and advancement. Firstly, this chapter explains the major problem and obstacles that makes efforts unsuccessful for developing secure web applications. Next, this chapter distinguishes three basic security properties that a web application should possess: validation, integrity, accuracy and portray the comparing vulnerabilities that damage these properties alongside the assault vectors that contain these vulnerabilities.
