The Four Fundamentals of Cybersecurity

• Protect the device. Smartphones, laptops, pads, tablets, and about anything that connects online should be protected using state-of-the-science device protection solutions.
• Protect the connection.
• Protect email communication.
• Protect and back up electronic documents and files.

Essential steps in protecting web apps from attacks include applying up-to-date encryption, setting proper authentication, continuously patching discovered vulnerabilities, avoiding data theft by having secure software development practices.

Examples of Network Security includes Antivirus and Antispyware programs, Firewall that block unauthorized access to a network and VPNs (Virtual Private Networks) used for secure remote access.

Transport Layer Security (TLS) is the successor protocol to SSL. TLS is an improved version of SSL. It works in much the same way as the SSL, using encryption to protect the transfer of data and information. The two terms are often used interchangeably in the industry although SSL is still widely used.

An intruder is someone who enters a place or situation despite not being invited.

This is known as nonrepudiation. In addition, information assurance extends to systems of all kinds, including large-scale distributed systems, control systems, and embedded systems, and it encompasses systems with hardware, software, and human components.

These goals form the confidentiality, integrity, availability (CIA) triad, the basis of all security programs.

Which four applications are used as Web security applications?…What is the most dangerous hacker tool?

• Acunetix.
• Nmap.
• Metasploit.
• Wireshark.
• Nikto.
• John the Ripper.
• Kismet.
• SQLninja.

Insecurity is however not fundamental to the web platform. As a matter of fact, the modern web offers a variety of powerful security features that help stop a hacker. Unfortunately, not many developers have the knowledge and skills to leverage these security features to their full potential.

In this course, you’ll learn from experts in the field about the fundamentals of web security and some of the latest threats and their defenses. You’ll gain a deeper, technical understanding of cybersecurity, the Internet’s common and emerging vulnerabilities, and techniques for addressing those vulnerabilities.

Web applications are inherently insecure, as aptly illustrated by a pile of recent events. Insecurity is however not fundamental to the web platform. As a matter of fact, the modern web offers a variety of powerful security features that help stop a hacker.

Damn Vulnerable Web Application (DVWA): A web app full of vulnerabilities to exploit. Students use it to learn the art of web application security. To specialize in web application security assessments, you need to be experienced in writing and reading multiple programming languages.
