Are you a Java web developer and want to write secure code? Do you want to learn Ethical hacking and Web application security? With this hands-on injection attacks course you will start learning web security using one of the top vulnerabilities of OWASP Top 10 list. Injection attack is still listed in top 3 attacks in the OWASP Top 10 and it is important to prevent against injection attacks to develop secure web applications. Krzysztof Telka: "Nice examples, where the host is presenting step by step how to exploit the application and then how to prevent. Lot of nice tools, features to check and examine the web page in case of hackers attack. CSV/Log4J/SQL made big wow effect on my face. The atendeers they will not be dissapointed Great job Ali, Thank you!"You can always use the latest versions for spring boot, and other dependencies in this course. I will be constantly updating the dependency version in the last section's lectures. You may check that to see the required code and configuration changes for updated versions. Also if you would like to use subtitles during the course, you can turn on the captions on videos. I suggest using subtitles to make it easier to follow the lectures.

Lecture 1- Introduction of servo motor and servo drive hardware- Setting up a Servo systemIn this training lecture, you will get acquainted with servo motors and servo drives. What are the parts of a servo drive and servo motor and what models of PLCs do we need to control the servo drive through pulse?Lecture 2- Set up a Servo with pulse output- Show PLC wiring- Differences in types of pulse outputs- How to connect PLC and Servo- How to choose a servo- Introducing servo Inputs and outputsIn this lecture, you will get acquainted with some of the servo settings and we will explain servo drive cabling. You will also learn about different types of pulse outputs and then work with the inputs and outputs of a servo drive. Finally, we will teach you how to choose a serving system for your specific application.Lecture 3- Servo wiringIn this chapter, you will learn wiring between PLC and ServoLecture 4- Introducing the ACC instructionIn this chapter, you will get acquainted with the ACC instruction.In this chapter, you will get acquainted with the ACC instruction.ACC(888) outputs pulses to the specified output port at the specified frequency using the specified acceleration and deceleration rate.ACC(888) starts pulse output on the port specified in P using the mode specified in M using the target frequency and acceleration/deceleration rate specified in S. The frequency is increased every pulse control period (4 ms) at the acceleration rate specified in S until the target frequency specified in S+1 and S+2 is reached.The pulse output is started each time ACC(888) is executed. It is thus normally sufficient to use the differentiated version (@ACC(888)) of the instruction or an execution condition that is turned ON only for one scan.Lecture 5
