We live in globally connected world which faces globally distributed cyber threat. These threats are not restricted by geographical boundaries and target at all technologies, Hardware, Software, service providers and the user Consumer, the private and public sector. The threats are all time high in terms of experience and volume and continue trend upward. Now days we can see that cyber security is popularly discussed topic among all I.T and Non- I.T firms due to increasing percentage of cyber-crime so every government and private organization are concerned about the security of their data, system, hardware, software etc. from being the victim of cyber-crime so all top mnc’s and government organization such as army have installed high security system so that no one reach their data and hardware etc. Now days we can see that security system are getting upgraded with high security so that any attacker or hacker cannot reach your computer or your content easily. We can take the example google.com in terms of security how they have made secured e-mail system as the user login their account they are not able to directly access their account first google identify whether right person is accessing the account or not by just sending 6 digit code to their hand phone via text message then user enter that code then they are able to access they account this security system of google prevent user from getting their email account hacked some time we have some confidential mails such as credit card number, company meeting details etc. so user don’t want these discussion to be published publically so that why security of email account is necessary.

• PC Maintenance Functionality: Good security software functionality doesn’t end on virus protection. The software need to check whether users pc is working properly or not such as speed testing , proper memory utilization etc. if pc is not working properly need to rectify all those errors to bring back user pc to prefect working state such as proper memory utilization.
HARDWARE SECURITY:
Basically Hardware Consist of physical devices such as server mainframes, external or portable memory, storage devices, computers etc. one of the important measures in hardware security from many businesses is the network security and server security.
The NSA is a U.S. intelligence agency responsible for providing the government with information on inner and foreign affairs, particularly for the prevention of terrorism and crime. The NSA maintains several database networks in which they receive private information on American citizens. The agency has access to phone calls, emails, photos, recordings, and backgrounds of practically all people residing in the United States. Started in 1952 by President Harry Truman, the NSA is tasked with the global monitoring and surveillance of targeted individuals in American territory. As part of the growing practice of mass surveillance in the United States, the agency collects and stores all phone records of all American citizens. People argue that this collected information is very intrusive, and the NSA may find something personal that someone may not have wanted anyone to know. While this intrusion's main purpose is to avoid events of terrorism, recent information leaks by Edward Snowden, a former NSA contractor, show that the agency may actually be infringing upon the rights of the American citizen. Whether people like it or not, it seems that the NSA will continue to spy on the people of the United States in an attempt to avert acts of terrorism. Although there are many pros and cons to this surveillance of American citizens, the agency is ultimately just doing its job to protect the lives of the people. Unless a person is actually planning on committing a major crime, there is no real reason for citizens to worry about the NSA and it's invasion of our privacy. The agency is not out to look for embarrassing information about its citizens, rather, only searches for and analyzes information which may lead to the identification of a targe...
We all have heard the quote “Life, Liberty, Land, and the Pursuit to Happiness” and that is the promise of a life here in America. As Americans we pride ourselves on these freedoms that allow us to live everyday. We are one of the only countries that have this promise and it is what draws people from all of over the world to come here. Our founding fathers of the United States of America wrote these words, having no idea the impact that they would have for the rest of this countries history. Those words were the foundation for government, and it wasn’t perfect at first but slowly it matured into what we have today, strong and powerful. To other nations America is seen as the World Power, and a somewhat perfect nation to live in. Unfortunately corruption, scandals and controversies have tainted our once golden glow, and other nations are weary of watching their steps. One of the most controversial elements to our government is the NSA. Hidden in the shadows from American and global knowledge is what the NSA is actually doing and watching out for. Only very recently has the NSA been ripped from the shadows and brought to light what exactly is going on inside those walls. They are “spying” on not only America’s personal data, but foreign leaders as well. The NSA says it’s for the safety for everyone against terrorism and attacks. However, it has gone way to far and violates a constitutional right, privacy. The NSA has overstepped their boundaries, and spying doesn’t seem to make a difference in safety.
These types of montitoring have a good side and a bad side. The Patriot Act is an Act of Congress that was signed into law by President George W. Bush in 2001 after 9/11. Its backronym, U.S.A.

A hardware firewall is used most often when multiple devices on a network need to be protected by a firewall. Hardware firewalls are a necessity if you need to have a centralized point for protection and easy management of the firewall. You can purchase hardware firewalls as just a physical device or as part of broadband router that already has the firewall built into it. Hardware firewalls can be some-what effective with very little, and sometimes no, effort on the users part in terms of actually configuring the device. Most hardware firewalls come already set with predefined rules on what is ok to pass through onto the network and what is not ok to pass through onto the network. Almost any computer user can plug in a hardware firewall, adjust a few settings and be on their merry way. But being how this device is made to protect your computer(s), your network, and possibly your assets, it would behoove you to learn the specific features of the firewall, what it allows and what it doesn’t allow, and how to enable and disable those features. Once you know how everything works you should test your firewall for optimal security and protection. Firewalls are not all created equally so it is important that your read all documentation that came with the device and go over the manual to get a full understanding of what exactly you have gotten yourself into. Your hardware firewall should always sit on the outermost portion of your logical network. This is known as the perimeter of ...
Network Security is the protection of the computer’s network though out the entire infrastructure. It can protect very important information and computer files to help prevent theft, spyware, malware, viruses, and more. Depending on if you have a public or private network, can determine what type of security settings you need for your network. All people are different on what they want to have secured or not, but most people do not know how to prevent people or things from getting in their network. “You must have a general understanding of security terminology and specifications as it relates to configuring hardware and software systems.”(Roberts, Richard M. 599). That quote states that by knowing and understanding security terms and specifics, you can
Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help to stop unauthorized users or intruders from accessing any part of a computer system. Detection helps one to determine whether or not someone attempted to break into a computer system, if they were successful, and what they may have done.
To understand the term Cyber Physical System, first we should know what is Cyber and physical. So, Cyber term related with the calculation, control and communication that are discrete, logical and switched. Physical term related with natural and man-made systems governed by the laws of physics and operating in continuous time.
When the entire body of knowledge concerning passwords is evaluated a few things become abundantly clear. First, passwords are going to be around for some time yet. There simply are no present alternatives that are cost competitive with passwords or that users can adopt in a successful manner. While it is certainly a noble effort to explore replacements for passwords, we cannot refuse to acknowledge their continued existence in the foreseeable future.
In today’s society technology is used for everything. With the invention of computers and the internet this open doors to the cyber world. Today you can do almost anything without having to leave your home. The internet gives us the opportunity of shopping online, ordering food online, working from home and video chatting with friends and family across the world. Everyone has a computer and internet access in their homes. While the internet is really convenient it also opens doors for cybercrimes, loss of privacy and the need for computer security.
To combat those threats and ensure that e-business transactions are not compromised, security technology must play a major role in today's networks. Why Networks Must Be Secured? Attacks: -. Without proper protection, any part of any network can be susceptible to attacks or unauthorized activity. Routers, switches, and hosts can all be violated by professional hackers, company competitors.
Technology has revolutionized the world. Nowadays, people depend on technology to modify, store, and organize their data and information. Therefore, it is significant that users consider the risks and protect their computers, electronic devices, and data. The data information from online purchase is valuable and important for users. Digital security risk has become a serious problem in the society.It could lead up to a loss of or damage to computer or mobile device. Digital security risks include unauthorized access and use of electronic device, internet and network attacks, hardware theft, software theft, information theft, and system failure. The common examples for digital security risks are intercepting wireless communications, virus attack,
The internet and other telecommunications technologies are encouraging advances in virtually every feature of society and all over the world. For instance, promoting commerce, improving education and health care, fostering participating in democracy in the United States and abroad, and facilitating communications among family and friends, whether in the neighborhood or around the globe. Regrettably, may of the attributes of this technology, low cost, ease of use, and anonymous nature, among others, make it an appealing medium for fraudulent scams, child sexual exploitation, and increasingly, a new concern referred as cyberstalking.
A computer system consists of hardware and software. Hardware is the slang word for the physical components?keyboards, mice, circuit boards, monitors and cables. Hardware needs some maintenance, such as appropriate, safe cleaning, and must be protected from dust and heat. Dust buildup can even cause overheating. Some maintenance, especially moving computers, is best done while the equipment is off. Keep track of your hardware instruction manuals. Use a notebook to keep track of your equipment?serial numbers, dates of purchase, and problem logs. Don?t mix in your personal, social information with this technical tool. Be careful with the routing and attachment of cables. Bringing food, drink, and magnets around computers invites trouble.

Internet technology is accelerating the rate of globalization. Email, in particular, is now one of the fastest ways for us to communicate with each other, and to do business, making our world much smaller and more immediate. This same technology that can enhance our lives and accelerates the pace of global change can also destroy our personal privacy at the same rate.
