Apart from all this, you also get to learn to secure The Web and its components, like patching flaws and preventing malicious exploitation.

These is amazing books for those who want to start learning Kali Linux from scratch. In this book, you will find very basic things about Linux, All about Linux commands. Before you start to learn Ethical hacking, you must get comfortable using the command line and that is just what this book focuses on.

Finding Vulnerability Assessment and Exploitation Techniques are very important things to start with ethical hacking or bug hunting. The only goal of this book is to provide very basic to advance techniques of gathering information on the target.

You can get this book if you want to be a master in Kali Linux. These were some of the most amazing books you will ever find to learn Kali Linux. Beginners, as well as professionals, can look up to these books to expand their knowledge. These books are helpful if you get stuck at anything or if you wish to learn something new in Kali Linux. If we have missed out on any such helpful book to learn Kali Linux from then, please let us know in the comments section.

Knowing all the potential weak points is more complete for the realization of pene- our goal. To do this the first thing that we are going tration test. This is accompanied by many to do is to conduct a port scan with nmap. In this tools of all kinds.

We will focus on the following: Information Gath- ering, search vulnerabilities, exploitation and Post exploitation. It is important to know that: in this article you are working with a series of tools for a specific pur- pose, but this does not mean that the tool can only be used for this purpose.

The vast majority of the tools have multiple uses. Nmap: Information gathering When we are ready to perform an attack, the first and most important step is the collection of infor- Figure 1. Result of scan with Zenmap. The Some of the services that are attacked : scan showed a few open ports on the server, and this may give us some clues as to where to find Port 21 FTP potential vulnerabilities.

The information which has Port pop3 taken us back is quite juicy, the server that we are Port mysql attacking has more of a role assigned, therefore more points to that attack. These protocols and their connec- tion, have a very robust encryption, which is why it is more complex to obtain a key using brute force, or crack a password snifing the trafic on a LAN.

As an example; both by the port 21 as the could be attempting to perform a brute-force at- tack. On the other hand, we have port that tells us that mysql installed. We will do some checking typical to perform a pen- etration test, such as trying to access an anonymous Figure 2. Acces denied for mysql backend user FTP, or verify access to mysql is enabled. However, having a mysql installed and see so many open ports makes us think that the web that we are attacking have more than one database dedicated to various services, for example, for the main page, a database, for the blog other, and so on for each part of the web.

This can mean that some of the parts of the web page is vulnerable. The first of them nerabilities is doing a full scan of the web site. This option is intercepting and all the connections that are made less advised that the previous one, however, can with Firefox, Chrome, or any other browser.

It is less advisable to use gle point, that is to say, possibly the web to which this method, or better said, the handicaps of using we are attacking has multiple URL, between the as a proxy is, that if you do a full scan on a web- BLOG, the main page, the access to the extranet, site, OWASP runs through all the URL of the page access to suppliers, and so on using as a proxy and tries to find vulnerabilities in each of the par- OWASP interceptions exclusively part of the web ties of the web.

This implies that the IDS or firewall server that we want to attack. OWASP when perform a full scan, launches all possible attacks, grouping the vulnerabilities found based on their criticality. Once that we already have the result of the scan- ning, the most advisable is to perform a first look Figure 5.

Figure 4 is the result already exported and in de- tail on the vulnerabilities found. Figure 5, is the result of XSS. Figure 6. Showing the databases with sqlmap Figure 7. Results of the table containing the users Figure 8. Among other vulnerabilities, we found a possible failure of SQL injection.

Sometimes the users and passwords are in dif- ferent tables, however this is not a problem, we cannot continue with the process of intrusion. Fig- ures 7 and 8 show the users and passwords in dif- ferent tables. And as we saw earlier, one of the open ports was precisely the Thus, we tried to enter and Figure 9.

Also, we have had access to the FTP server where are housed all of the files of the web site, and where we could get a remote shell. These 3 tools are in the Top Ten of Kali Linux. These are without doubt the tools to be considered in order to make hacking attacks and penetration testing.

The final solution must scale with grow- ing business demands for security assessments so automation of distributed scanners was a primary consideration. Additionally, the scanners must be cost-effective to deploy, easy to manage more on this later , and enable centralized reporting. Figure 1.
