Applied Microsoft NET Framework Programming or Network Security Foundations

Applied Microsoft .NET Framework Programming

Author: Jeffrey Richter

The Microsoft® .NET Framework allows developers to quickly build robust, secure ASP.NET Web Forms and XML Web service applications, Windows® Forms applications, tools, and types. Find out all about its common language runtime and learn how to leverage its power to build, package, and deploy any kind of application or component. APPLIED MICROSOFT .NET FRAMEWORK PROGRAMMING is ideal for anyone who understands object-oriented programming concepts such as data abstraction, inheritance, and polymorphism. The book carefully explains the extensible type system of the .NET Framework, examines how the runtime manages the behavior of types, and explores how an application manipulates types. While focusing on C#, it presents concepts applicable to all programming languages that target the .NET Framework. Topics covered include:

. The .NET Framework architecture

. Building, packaging, deploying, and administering applications and their types

. Building and deploying shared assemblies

. Type fundamentals

. Primitive, reference, and value types

. Operations common to all objects

. Type members and accessibility

. Constants, fields, methods, properties, and events

. Working with text

. Enumerated types and bit flags

. Array types

. Interfaces

. Custom attributes

. Delegates

. Error handling with exceptions

. Automatic memory management

. AppDomains and reflectionIncludes coverage of C#

Network Security Foundations

Author: Matthew Streb

The world of IT is always evolving, but in every area there are stable, core concepts that anyone just setting out needed to know last year, needs to know this year, and will still need to know next year. The purpose of the Foundations series is to identify these concepts and present them in a way that gives you the strongest possible starting point, no matter what your endeavor.

Network Security Foundations provides essential knowledge about the principles and techniques used to protect computers and networks from hackers, viruses, and other threats. What you learn here will benefit you in the short term, as you acquire and practice your skills, and in the long term, as you use them. Topics covered include:

• Why and how hackers do what they do

• How encryption and authentication work

• How firewalls work

• Understanding Virtual Private Networks (VPNs)

• Risks posed by remote access

• Setting up protection against viruses, worms, and spyware

• Securing Windows computers

• Securing UNIX and Linux computers

• Securing Web and email servers

• Detecting attempts by hackers
