——————————— Computer Crimes and Security——————————
As the technology is increasing day by day, many people fall victim to cyber theft. This high development of technology and the availability of internet to most of the public, broadens the pathway of cyber-crime. Cyber-Security was once not a serious issue. But, now many people are complaining about their credit card information getting stolen or sudden drop of credits in their bank account.
The internet has become the integral part of today’s generation of people. Many people share their information out in the web through social networking sites like Facebook, Twitter, Instagram etc. Internet has touched every aspect of life right from the beginning to the present. As people share their personal information online; most of their accounts get hacked by cyber-criminal or in other word's black hat hackers. And, trusting internet nowadays isn't a wise thing to do.
With the growing use of the internet by people, protecting sensitive information has become something which must be taken into consideration, quite seriously. Otherwise, the internet can be one of the dangerous places to visit if one's sensitive information isn't being protected. If a computer doesn't have proper security controls then it has high chances of getting infected by malwares, malicious logics and hence, any type of information in that computer can be accessed easily within moments. And, there are many millions of websites on internet which are infected with malwares and spy-programs. Which allows a hacker to gain illegal access to the specific computer, once the computer has browsed the domain name of the malicious website or if the spy-program is downloaded into the computer. It is very important to stay secure while you are online or else it might be very risky to lose your personal information.
Cyber-attacks can be caused due to negligence and vulnerabilities. One can be a victim of cyber-attack due to his own ignorance of the vulnerabilities which his system shows. Which also means that one can stay secure online by blocking ways by which a hacker can come. He can do this by installing an anti-virus (such as, Avira, Norton, Macafee, Kaspersky etc.), updating the application which he uses for browsing internet etc. Few other ways are, not surfing websites that isn't secure. Well, this might sound a minor thing. But, it's one of the most important thing which must be followed in order to stay secure online. According to a study conducted on 2012, most of the internet users don’t bother whether the website they visit is secured or not. Due to this, many of the information registered on the website gets duplicated. Such as, credit card initials while making a purchase, their official e-mail password while linking their account. All these can prove fatal if the hacker gets all this personal information.
One more thing what a person can do to stay secure is; by not clicking a link or downloading an application, which is sent via mail to him by an un-authorized person. If the e-mail shows up in spam folder then also he shouldn't open it. In case, if the person downloads the application then his anti-virus must be turned on, in order to scan the downloaded application. Otherwise, his PC could be vulnerable to viruses and malware program. If he doesn't have an anti-virus and he downloads the application then what's going to happen is; his monitor screen suddenly flashes and shuts down. And, when he restarts his PC, he notices that it doesn't function as it used to before. These symptoms are cause of the presence of virus inside his desktop.
We as a human tend to ignore things most of the time. And, this can be very dangerous when it comes to surfing web online and downloading applications. Hackers make use of paths which we tend to ignore. And, most of the attacks which we receive from them can be brutal. In earlier this year, there were a team of black hat hackers who created a ransomeware ware called Wannacry. Within moments of its release to the internet, many multi-million companies including FedEx and Amazon faced huge loss. This ransomeware is so powerful that it spreads through a connected network.
Normally, what firewalls do is; they block the data coming from outside the network. They pretend as a thick layer of filter that denies the penetration of un-wanted or harmful data that comes from the internet. So, in order to have a strong firewall, all you need to do is block all the outbound connection and allow all the inbound connection. This makes sure that the data on the internet can be accessed through inbound connection. But, no user will be able to penetrate into you network unless and until he is connected to your network. Meaning, blocking the outbound connection, you make the firewall stronger in such a way that other users who aren't connected to your network won't be able to access your files or see the devices connected to your network.
Hope this helps :)
