This presentation on Cyber Security training will help you understand what is Cyber Security, basic terminologies, how an email works, common types of attacks, functions of malware and various sources of malware. Cyber Security is the technology and process that is designed to protect networks and devices from attack, damage, or unauthorized access. .Now, let us get started and understand Cyber Security in detail. Below topics are explained in this Cyber Security training presentation: 1. What is Cyber Security? 2. Basic terminologies 3. How do you get internet? 4. Common types of attacks 5. Functions of malware 6. Sources of malware Simplilearn’s Introduction to Cyber Security course is designed to give you a foundational look at today’s cybersecurity landscape and how to evaluate and manage security protocol in information processing systems. You will learn about information security concepts and technologies, the principles behind security architecture, how to mitigate vulnerabilities and threats to your systems, and how to implement risk and incident management to protect your infrastructure from cyber attack. What are the course objectives? In this Introduction to Cyber Security training course, you will gain a comprehensive overview of cybersecurity principles and concepts and learn the challenges of designing a security program. You will hear about evolving new threats such as social engineering attacks and learn how to mitigate their impact on organizational security. And you will be taught to develop and manage an Information Security Program, perform business impact analysis, and carry out disaster recovery testing. What are the career benefits of this course? The demand for cybersecurity experts has increased significantly over the last few years as companies become more dependent on the Internet and its vast facilities, and as data breaches, hacking and cyber crime reach new heights. The cyber security market is expected to grow from USD 152.71 billion in 2018 to USD 248.26 billion by 2023, at a compound annual growth rate (CAGR) of 10.2 per cent. The annual average salary of cybersecurity professionals ranges from $110,000-170,000 (Source: Glassdoor), and there are currently more than 43,000 cybersecurity positions available in the U.S. (Souce: Indeed.com) Upon completion of this course, you will become familiar with cybersecurity methodologies and be able to: 1. Leverage an enhanced awareness of cybersecurity principles and concepts 2. Analyze appropriate types of controls to counteract various threats 3. Combat social engineering attacks such as phishing, malware, spyware, adware, ransomware, and Bluetooth attacks 4. Determine and analyze software vulnerabilities and security solutions to reduce the risk of exploitation Learn more at https://www.simplilearn.com/introduction-to-cyber-security-course

As the name suggests, keylogger records all the hits on the keyboard
Most people use it to get passwords and account details

84. Password attack – Shoulder surfing
As the name suggests, the attackers observe the user’s keyboard by looking
over the user’s shoulder

85. Password attack – Rainbow table attack
There are rainbow tables that contain precomputed hash values
Attackers use this table to find the password of the user
