Security & Surveillance in Tanzania

The widespread adoption of powerful network computers for business and personal use has spawned entire branches of computer and network security. Companies need the knowledge and skills of security experts to conduct audits and make decisions that are consistent with their requirements. And since many companies are inherently dynamic, and their employees access information resources both locally and remotely, the need to create a secure computing environment increases even more. Unfortunately, in many companies (and many ordinary users), security issues are second to the tasks of increasing performance, productivity, and financial issues. The necessary security measures are often taken after the fact - when a malicious intrusion has already occurred. Security experts agree that the right measures, taken before the internal network connects to an open network (such as the Internet), will stop most intrusion attempts. Computer security is a general term that encompasses a wide area of ​​computer and information technology. In areas where co Security & Surveillance in Tanzania mputer systems and networks are used on a daily basis to perform business transactions and access vital information, data constitutes a significant part of all assets. Certain concepts and assessments have become firmly established in everyday business vocabulary, such as total cost of ownership (TCO) and quality of service (QoS). These assessments assess data integrity, high availability, and other aspects in terms of planning and process management costs. In some industries, such as e-commerce, data availability and trust can be critical. Many readers may recall the movie Wargames, starring Matthew Broderick, in which a student hacked into a US Department of Defense (DoD) supercomputer and accidentally created the threat of nuclear war. In this film, Broderick's character used a modem to connect to a military computer (called WOPR) and play with an artificial intelligence program that controls all of the rocket launchers. The film was released during the Cold War between the USSR and the USA in 1983 and had some success. This film inspired many to implement some of the tricks used by the young protagonist to break closed systems, including war dialing - scanning phone numbers with modems for a given combination of region code and prefix. More than 10 ten years later, after four years of legal proceedings involving the Federal Bureau of Investigation (FBI) and computer professionals from around the country, the famous hacker Kevin Mitnick was arrested. He was charged with 25 computer and access device crimes and $ 80 million in damages resulting from the loss of intellectual property and software source code from Nokia, NEC, Sun Microsystems, Novell, Fujitsu and Motorola. Then the FBI called this case the largest computer-related case in the entire history of the United States. He was convicted and sentenced to 68 months in prison, of which he spent 60 and was released early on January 21, 2000. But he was still prohibited from using computers or consulting with them until 2003. Researchers say Mitnick was a master in social engineering, exploiting human weakness to gain unauthorized access to passwords and systems. As the use of open networks for the secure storage of personal, financial and other classified information has expanded, information security has evolved over the years. There are many striking examples, for example, the cases of Mitnik and Vladimir Levin (for more information, see section 1.1.2 History of Computer Security), forcing a variety of organizations to think about how to transfer and store information. In many ways, it was the popularity of the Internet that caused the rapid development of data protection technologies. The number of people using their personal computers to access Internet resources is constantly growing. The Internet, which gave the world from information retrieval systems to e-mail and e-commerce, is deservedly considered one of the most important achievements of the 20th century. However, the Internet and early protocols were designed as trust-based systems. That is, the Internet Protocol (IP) was originally designed to be insecure. The TCP / IP connection stack lacks approved security standards, making it open to malicious users and programs running on the network. Modern developments have made interaction over the Internet more secure, but still a number of cases of wide interest suggest that nothing is completely secure.
