Hacking, which has been a neighborhood of computing for over 50 years, maybe a very broad discipline, which covers a good range of topics. the primarily reported hacking was in 1960 at MIT and therefore the term ‘Hacker’ was used.
For non-geeks, there may be a short introduction. Computer software consists of computer programs, which give instructions on how the hardware should perform certain tasks. This software is often prepared by programmers, who have full access to the whole program. The programs are then sold to users with strict rules or protocols by which they’re accessible only to certain authorized persons (usually with passwords) for reasons of security. Theoretically, nobody except these authorized persons has access to use these.
How can others obtain unauthorized access?
- the first programmers, who have prepared the ASCII text file , and have invariably provided their own entry points trap-doors and passwords.
- Earlier users who are not any longer authorized users, but whose passwords haven’t been deleted.
- Other unscrupulous persons who wish to access the system for ulterior motives.
- Since there’s such a lot activity and business travel by computers, and most computers are connected by the web , they’re hospitable be accessed by various persons via the web .
- Computers also are susceptible to attack by malicious software (mal-ware) and virus attacks, which leaves them hospitable attack by hackers and mal-ware. These ‘virus infections’ and ‘worms’ are introduced by persons who wish to hack into the system and steal information or make entire systems crash or destroy the whole data stored.
Just as virus attacks in computers are prevented by anti-virus software like MacAfee, etc. companies protect themselves from hacking by employing ethical hackers. EC Council defines an ethical hacker as ‘an individual who is typically employed with a corporation and who are often trusted to undertake an effort to penetrate networks and/or computer systems using an equivalent methods and techniques as a malicious hacker.’
It refers to the act of locating weaknesses and vulnerabilities of computer and knowledge systems by duplicating the intent and actions of malicious users.
It is also referred to as penetration testing, intrusion testing, or red teaming. It requires them to check out client networks as potential malicious attackers, then devises the proper safeguards to guard clients against attacks. |
So why are ethical hackers needed?
- they’re needed to spot and seal all possible points of access by hackers, which might be individuals or sophisticated software, including ‘worms’.
- In simple language, an ethical hacker thinks and works like an unethical hacker to seek out and exploit vulnerabilities and weaknesses in various systems, and the way they will be breached.
- Then he devises methods to guard the vulnerable points by erecting firewalls, stronger passwords, frequently changing passwords, using iris scans or fingerprints additionally to passwords, encryption, and so on.
4 They also got to prevent ingress (entry) by the first programmers who created the software and by persons who are not any longer authorized to log into the system.
- they’ll also suggest VPN (Virtual Private Network), a secure tunnel between a computer and destinations visited on the web . It uses a VPN server, which may be located anywhere within the world, and provides privacy. VPN will do the work to stop someone snooping your browsing history, or spying on you. VPN will cause you to browsing from the server geo-location not your computer’s location so we’ll remain anonymous.
With most personal data being available today over the web for a price, Data Privacy may be a serious concern; hackers can easily buy your personal data and steal your data using your passwords for other sites (since most people have an equivalent weak password for various applications and infrequently change passwords). they’re going to educate users on the way to choose difficult passwords, where to record or not record the passwords, and the way frequently you would like to vary passwords.
