With the increasingly use of computer and explosive growth of the Internet has brought many good things: The improvement of systems security to prevent criminal hacker has become an important concern to society. There are many ways to protect those information systems; it seems that the Ethical Hacking is a better way. Therefore, whether to teach or not teach the "Ethical Hacking" as a course in Tertiary education has become an interesting argument.
We provide details of the systems architecture of the individual components and the common framework within which they operate. Most of the options in the user interface are pretty self explanatory.
At the top, there are fields for you to input the IP address of the system that you are trying to crack, and the port number. There are also a couple of slide bars that allow you to choose how many simultaneous connections you want to make to the remote host and what the timeout period is for a non responding connection.
Both of these options are already set to optimum values and should not be changed under most circumstances. This tool has not been updated for many years. Still, it can be useful. Obi Wan is written to carry out brute force security testing on Web servers.
The idea behind this is web servers with simple challenge-response authentication mechanism mostly have no switches to set up intruder lockout or delay timings for wrong passwords.
In fact this is the point to start from. Like other programs for UNIX systems passwords crack or NT passwords l0phtcrack Obi Wan uses wordlists and alternations of numeric or alpha-numeric characters as possible passwords.
Since Web servers allow unlimited requests it is a question of time and bandwidth to break in a server system. The most interesting targets are web based administration front ends like Netscapes Server Administration.
If you can break in, you are able to create accounts, stop the server and modify its content. It is a Web password cracking tool that can work through a proxy. Obi Wan uses wordlists and alternations of numeric or alpha-numeric characters as possible passwords.
The most popular port scanner for Linux, Nmap, is also available for Windows. Nmap can scan a system in variety of stealth modes, depending upon how undetectable you want to be.
Nmap can determine a lot of information about a target, like what hosts are available, what services are offered and what OS is running.
Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.
It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X.
In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer Zenmapa flexible data transfer, redirection, and debugging tool Ncata utility for comparing scan results Ndiffand a packet generation and response analysis tool Nping.
For example, listing the hosts that respond to pings or have a particular port open. Typical uses of Nmap: Nmap is a tool that can be used to discover services running on Internet connected systems.
Like any tool it could potentially be used for black hat hacking, as a precursor to attempts to gain unauthorized access to computer systems. Nmap is more often used by security and systems administration to assess networks for vulnerabilities. System administrators can use Nmap to search for unauthorized servers, or for computers that do not conform to security standards.
Nmap is related to vulnerability assessment tools such as Nessus, which test for common vulnerabilities in open ports. The included NSE scripts that are packaged with modern versions of Nmap are able to perform vulnerability checks against discovered services.
A number of various sites have been scanned using NMAP. The figure below depicts the results obtained after scanning RTU website. Figure 1 shows the basic details of RTU website including the IP address, number of total ports available, number of open ports discovered, performing RPCGrind scan and much more other relevant details.
It outlays the host details of RTU website which includes the host status that depicts the number of total ports scanned, number of open ports available, number of filtered ports. Further, the type of operating system used and its accuracy of being correct is also illustrated.
It also shows the list of open ports on RTU website. It depicts the port number, protocol used on that port, its state of being open or closed or filtered, type of service provided on that port and the version details.
Exploits take advantage of vulnerability by compromising or destructing the vulnerable system, device, or application. Remediation is the process of repairing or providing a remedy for vulnerability, thereby eliminating the risk of being exploited.
Vulnerability scanning is used to identify and evaluate the security posture of a network. Historically, scanners were developed for specific purposes such as scanning only Windows desktops, applications, or network devices.Without judging the merits of each individual case, it’s clear that reporting on the private data of millions of ordinary Americans that has been stolen by unknown hackers raises serious ethical questions.
Reporters are digging through people’s personal email addresses, home addresses, physical descriptions, and preferences, sexual or otherwise. Hack Essay. Words Nov 1st, 6 Pages. Show More. EXECUTIVE SUMMARY The term ‘keylogger’ itself is neutral, and the word describes the program’s function.
The goal of an ethical hack is neither to do damage nor to download any valuable information –it’s more a service for a client to test his environment on how it would.
Once the contractual agreement is in place, the testing may start as defined in the agreement.
It should be noted that the testing itself poses some risk to the customer, since a criminal hacker seeking the transmissions of the ethical hackers could learn the same information.
Need for Ethical Hacking The process of employing someone to hack ones company is ethical hacking.
Ethical hacking is one of the tools that are used to judge the security programs of the organizations. It is also referred as penetrating testing, red teaming, intrusion testing, vulnerability and even security judgments.
Ethical dilemmas, also known as moral dilemmas, have been a problem for ethical theorists as far back as Plato. An ethical dilemma is a situation wherein moral precepts or ethical obligations conflict in such a way that any possible resolution to the dilemma is morally intolerable.
Included: computer essay content. Preview text: Hacking was a term that originated in s and is associated with the unauthorized use of computer and network resources. By definition, hacking is the practice of altering the features of a system, to accomplish a goal which is not in scope of the.
