IT Systems and many other networking technologies have controlled a large section of our lives. A substantial amount of people rely on a form of these technologies in day to day life. Communication, transport, leisure, workplace, health and many other areas are now very reliant on these newer networking technologies. This has now become a threat to civil framework and has shown us how vulnerable the systems in place have become. For example as the use of emails has grown there has been an evolution in malware and viruses which attach to emails without the receiver even noticing. In this modern day e-commerce which relies on computer systems for transactions to take place and has become a virtual marketplace and allows businesses to have online stores which makes it accessible for the customer. Customers can now buy services and goods without having to leave their homes. “While many computer systems collect audit data, most do not have any capability for automated analysis of that data” [Anderson, et al, 1995]. “The Internet is becoming increasingly dangerous; not only for large companies, but smaller networks are also being targeted by malicious activity” [Overall statistics for 2014]. Many of the technologies used within these systems are now being exploited by criminals trying to access information and perform other criminal activities. The main reason for this is because most of the infrastructure in place is controlled by IT systems and the security systems in place
Cyber security threats change quickly as Internet increases, and also the related dangers are getting to be progressively international. Being covered against cyber security threats requires almost all end users, actually the most complex versions, to know the particular threats in addition to enhance their particular safety measures with a continuing foundation. On April 28, 2014 President Obama has declared that the “cyber threat is one of the most serious economic and national security challenges we face as a nation” and that “America 's economic prosperity in the 21st century will depend on cyber security.” The internet enables and also helps people in a many ways and a example is collect, store, process huge amounts of data, which includes vulnerable data of small business, transactional and personal. Everything in this world is based on internet now a days.
The growth of the internet has allowed cyber criminals to attack any target anywhere and not even have to be local. Capabilities in internet speed and the out reach of the world wide web make this crime more desirable and easy to accomplish.
Cyber threats have increased dramatically over the past few years, with large companies such as Amazon, Netflex, PayPal, Wikipedia and most recently Equifax, experiencing high profile breaches. Traditional tools, defenses and responses have been strained with keeping up with the level and sophistication of an very organized and ubiquitous hacking community, which has coalesced into organized crime syndicates that the FBI and law enforcement continues to battle.
The world is becoming more and more digital everyday, things as simple as the lights in our houses can be linked to a network. Nevertheless, these networks can be a window of opportunity for cyberterrorist groups, or hacktivists to exploit. Technology has also given the resources needed for these groups to become more efficient at what they do, like increasing bandwidth speeds or more efficient computers for example, but also the same technologies can be used to strengthen security measures against these attacks.
The destructiveness of cybercrimes. The severity of incidents with the intent to damage and disable critical information network systems will increase.
The advancement of computer technology and networking has rapidly expanded communications but as we progress with the wage of the new world technology comes with it own costs. The same technology that provides useful services can be used against its users and benefit computer terrorist to get our information, take our identity and preview our personal lives without many of us knowing what has happened until it is too late. Continuous advancing technology provides criminals and terrorists with a variety of new tools and opportunities to conduct their agendas against current technology.
Terrorist cyber-attacks on national institutions will result in greater devastation than a cyber-crime directed against an individual. At the current rate in which technology is increasing, establishments must constantly upgrade their system’s security. If the national institutions fail to be vigilant to the present day cyber threats, they will become victims of terrorist cyber-attacks. “Our nation's government, military, scientific, commercial and entertainment sectors all operate on the same networks as our adversaries” (Alexander 18). A terrorist cyber-attack that is successful, has the potential to put people at risk, by allowing sensitive information to get into the wrong hands, disrupting resources, or by altering system information in corporations, to cause harm or confusion. Since a terroristic attack is focused on causing violence or chaos, the targets at risk would be “energy sources and electric grids, water and sewer systems, manufacturing, banks, transportation and communication networks” (Brenner 15).
It takes time and money to adjust IT security measures in response to evolving attack tactics. As defenders gradually update their security measures, attackers respond accordingly. Such arms-race dynamics lead to threats of increasing sophistication and efficiency. Today’s cybercriminals often have a long-term interest in their targets and often employ social engineering to get inside a protected environment. Their tactics commonly include malicious payload that attempts to compromise the victim’s system and may continue spreading within the organization. They also increasingly focus on weaknesses at the application, rather than system or network levels, to obtain data that provide the most value.
Digital communications technologies, such as the Internet, mobile smartphones and WiFi-enabled devices, have become part of everyday life. By dramatically improving access to information and real-time communication, innovations in communications technology have boosted freedom of expression, facilitated global debate and fostered democratic participation. The security risk assessment is an on-going process of discovering, correcting and preventing security problems. The risk assessment is an integral part of a risk management process designed to provide appropriate levels of security for information systems. The threat from cyber criminals and hackers has increased; as our dependent develop, prospect for them to prey on us are boosted. The cyber fraud is among the fastest growing form of crime in the world
The Internet has extended its reach over the last 15-20 years, so is malware (malicious software). Also it has evolved and become more complex and applying new tricks every day. Early forms of malware sought to generate attacks on basic areas of computer systems, but today its aims are increasingly evil, focusing on theft and other illicit activities. Malware has become much more of a concern for organizations; Today, in addition to individual computers and the networks of organizations both large and small, Internet connectivity also extends to devices such as gaming consoles and smartphones. And as computing architectures shift, protecting organizations, governments, and citizens from malware has become even more of a challenge for network experts.
Since the late 1980’s, cyber security has been a growing industry. Viruses such as the Morris Worm proved to the world that the internet was not a safe and secure architecture. In later years the Michelangelo virus, Melissa, and Concept began to push the IT industry for research on cyber security and antivirus protection.
There have been recent innovations in protecting the most important resources of the network. More advanced security technologies are employed on the network in order to take advance precautionary measures to avoid various security threats. According to various situations companies adopt the required security measure in order to address different types of unethical activities on the network.
The modern technology in the world is growing day by day. So to enable faster and simpler networking, the countries are developing and expanding their technology. Currently there are billions of Internet user and mobile phone connections all over the world. People all around the world are very much depended on consistent access of these channels. Popularity for Internet based networking is growing exponentially, but it come at a cost. The cost is the cyber attack and crimes are increasing rapidly around the world. The attacks like email staking, hacking computers, virus attacks, etc. There was one major cyber attack in year 2000, where around 45 million computer were attacked by the computer virus all around the world[1]. There are
Internet use has skyrocketed since 2000 to over 2.4 billion users worldwide, with 70% of those users logging on every day (The Culturist, 2013).These days it takes merely minutes for news to travel around the globe. Our airwaves are filled with tiny nuggets of information whooshing past us undetected; that is, until it is detected. In the 21st century, cyber security is an international issue. The threat of cyber warfare is very real and would be devastating beyond any conventional weapon imaginable. With the entire globe becoming more interconnected, an attack on online infrastructure could ground airplanes, control information access, hijack nuclear facilities, and perhaps most terrifyingly, bring the global economy to a
Nuts and bolts of computer networks. Computer networks consist of end systems, packet switches, and communication links. End systems—also called hosts—include desktop PCs, laptops, hand-held network devices (including cell phones, PDAs, and BlackBerries), sensors, and servers (such as Web and mail servers). Just as cities are interconnected by a network of roads and intersections, end systems of a computer network are interconnected by a network of communication links and packet switches. Communication links can be wired or wireless. Distributed applications. A computer
