Portable TOR Router with Raspberry Pi
Nowadays, internet has become an important part of everyone's lives. The internet has turned out to be a reliable tool for communication, data transfer and many more applications for people from all over the world. An individual's internet activities are being tracked and traced without their knowledge by various means. Thus, online security is a genuine worry for web clients who intend to visit interpersonal interaction locales, make an online transaction, or take an interest in internet diversions, as they need their protection to be ensured. Internet browsing is not anonymized as many Internet Service Providers (ISP's) could legally sell users information without informing users. People's internet activities are being tracked and traced by ISPs. Moreover, network spies and snooping attempts are very hard to be defeated as an ample network snooping tools are available in the market. These issues can be curbed by using a router that has anonymous browsing infrastructure. However, most of the routers that gives anonymous browsing are not portable. From this project, people will be able to browse anonymously without being traced. Besides that, network snooping and spying attempts can be defeated. Finally, a portable The Onion Routing (TOR) router can be created with a Raspberry Pi..
Chapter 5 – Data Hiding Using Encryption Techniques
In this chapter we will list different methods to conceal private data using encryption techniques. As discussed previously, steganography is considered a subbranch of cryptography, which is still considered the most secure method to transmit data in today's digital world. 
 
We begin talking about anonymous operating systems and how we can use them to conceal our identity online using anonymous networks like TOR and I2P. 
 
In the next section we cover disk encryption. This includes full disk encryption, operating system partition encryption, and single file encryption, creating encrypted vaults and encrypting our data before uploading it to the cloud. We also cover major attacks against encryption techniques and how we can mitigate them to achieve maximum security. 
 
In the third section of the chapter, we cover different methods to anonymize our location online. This includes the use of anonymizing networks such as TOR, VPN, proxy servers, and OnionShare to share files online. Readers will explore different web browser add-ons, which make browsers more privacy-friendly while surfing online. 
 
Later we talk about encrypting email communications. We give a brief introduction about the concept of private/public keys and digital signatures. We then present different methods of email encryption using GpG4Win with MS Outlook email client. We also demonstrate how to use a browser extension to send and receive encrypted emails online without installing any software. Finally, we give some free secure web mail providers that offer excellent security features to protect their users. 
 
In the next section readers will discover different services and tools that can be used to conduct private secure IM chat and VOIP communications. There are different services already available for this type of communication; however, the services presented in this section are considered the best in the field. 
 
In conclusion, the reader will find advice on how to select secure passwords for different accounts. Readers will find list of different techniques used to generate passwords automatically. More on some password manager software used to store passwords privately is provided at the end of the chapter.
DESIGN AND IMPLEMENTATION OF SYSTEM AND NETWORK SECURITY FOR AN ENTERPRISE WITH WORLDWIDE BRANCHES
The basic reasons we care about information systems security are that some of our information needs to be protected against unauthorized disclosure for legal and competitive reasons; all of the information we store and refer to must be protected against accidental or deliberate modification and must be available in a timely fashion. We must also establish and maintain the authenticity (correct attribution) of documents we create, send and receive. Finally, the if poor security practices allow damage to our systems, we may be subject to criminal or civil legal proceedings; if our negligence allows third parties to be harmed via our compromised systems, there may be even more severe legal problems. Another issue that is emerging in e-commerce is that good security can finally be seen as part of the market development strategy. Consumers have expressed widespread concerns over privacy and the safety of their data; companies with strong security can leverage their investment to increase the pool of willing buyers and to increase their market share. We no longer have to look at security purely as loss avoidance: in today’s marketplace good security becomes a competitive advantage that can contribute directly to revenue figures and the bottom line. Networks today run mission-critical business services that need protection from both external and internal threats. In this paper we proposed a secure design and implementation of a network and system using Windows environment. Reviews of latest product with an application to an enterprise with worldwide branches are given.
