Almost all programming language needs the concept of the data type. Since C# is a strongly typed language, it is essential to inform the compiler what kind of data these memory locations will hold. In this chapter, you will learn about the different data types that are supported by C#.
Operators are symbols in a programming language that tell the compiler or interpreter to perform specific operations on operands to produce the final output or result. You will learn about all the operators of C#.
Access modifiers are also known as access specifiers used to preserve the concept of encapsulation of data by specifically restricting the access of variable data using some particular keywords. These are used to specify a specific variable's accessibility or scope and functionality within a C# application.
C# is rich in features and keywords which help in making the language strong and versatile. Keywords are reserved words with special meaning that is known to the compiler. These keywords also have special significance and hence cannot be used as identifier name for variable-name, class-name or interface-name.
C# Classes are user-defined blueprints or prototype that is used to define real-world entities through objects. They bind data and its associated functions or operations into a single unit.
In this chapter, you will get to know about malware and computer viruses and different measures to maintain security and safety.
Maintaining the privacy of some of our real-world stuff is essential. Similarly, each and everyone's personal data on the web also needs some privacy. In this chapter, as a security professional, you must have a fair idea of how different tools, concepts, and technologies are used to preserve privacy.
Firewalls are both software programs and hardware components that preserve our security and maintain safety from unauthorized access to or from the external network. They act as a vital part of a comprehensive security framework for any network.
Network security is one of the essential cybersecurity branches, and protocols play a vital role in securing the network. In this chapter, you will learn about the most prominent network security protocols and their uses.
Ports are another important asset through which security can be breached. In this chapter, you will learn about the different measures you need to take to protect your system through ports.
Physical Penetration testing is the new branch of cybersecurity where the physical security is measured, and its existing strength in an organization, firm, or lab is measured. Weaknesses are uncovered before cybercriminals do these exploitations.
Before getting into the very in-depth of every concept, it is recommended to clear the concepts and terminologies related to cybersecurity and cybercrime. Each of the terms has individual meaning and is used in different scenarios in this security field.
