Hacking is a broad term that describes an approach to discovering secure systems by means of various techniques and strategies. A hacker, also known as a Penetrator, is a skilled and trained computer hacker who usually breaks into computer systems without permission through several different means. Some of the most common attacks include:
A computer hacker may choose to hack a computer system through a vulnerability or exploit – that is, to find out whether there are ways to gain access to a protected system without appropriate authorization. A penetration, on the other hand, is the illegal or unethical pursuit of such an action. Cyber criminals exploit or find holes in a computer system that are not known to the users and can be used to gain access to and/or make changes to the systems.
Hacking can be done for either ethical or malicious reasons. While ethical hackers hack for the public good, those who are engaged in this activity may do so for profit, planning unethical attacks, or as means of gaining illegal access to private data. In cases of public or corporate computer networks, the hacking tools used are generally the same. However, in more sensitive personal data (such as credit card numbers), it may be necessary to develop and maintain highly specialized hacking teams.
It’s often difficult to tell the difference between ethical hacking and malicious hacking. While both types of hacking attempt to gain access and control systems for the purpose of sabotage, they do so in different ways. For instance, the most common and widely recognized form of ethical hacking is the so-called “cyber attacks.” In these instances, hackers break into a system without authorization from owners or users in order to test the security of that system. Cyber criminals use software programs that perform remote system administration functions – essentially, taking over control of a computer or server remotely via the Internet and using that control to execute destructive or annoying programs.
More sophisticated than just a basic hacking effort are what are known as “phishing” and “malware” attacks. Phishing involves sending fake emails that appear to be coming from legitimate businesses, such as banks, websites, or other websites that consumers trust. Malware attacks, on the other hand, are typically performed by computer hackers who search for passwords and other information that can be used to completely takeover a victims system. Both of these types of attacks rely on stolen personal information. Because of this, it’s important to make sure that you’re keeping your anti-spyware up-to-date at all times and that you’re not allowing attackers to gain access to your computer’s operating system.
The methods used by cyber criminals are becoming increasingly sophisticated and many hackers have become experienced in executing attacks using such tactics. In the past, many hackers were operating covertly, undetected, and unseen, but as more attention is devoted to increasing the security of computer networks, more black hat techniques are being used by cyber criminals. With a more tight knit community for digital security experts, it has become much easier for them to find weaknesses in network security and carry out their attacks. For many companies, the cost of a company’s IT staff and the potential financial harm done to them through a successful attack is far greater than the cost of stopping a potential hack. As long as a company’s firewall is up and running and they regularly monitor their network, however, they will be able to protect themselves from cyber attacks.
