A Brief Note On Professional Seminar : Network Security

In the early days of computing, a hacker was primarily referred to as a computer guru, someone who is extremely technical with a high expertise in computer also known as “Expert Programmers”. Nevertheless, as technology is advancing at a face pace, hacking has adopted a completely different definition. The modern definition is someone who access a computer system primarily to steal or destroy information. Hacking has caused major harm in the realm of technology. Over the years, hackers have become much more lethal in their craft. They manage to break into complex information systems from entities such as banks, government agencies, and private businesses. Furthermore, they often manipulate their victims through social engineering in order to obtain financial benefits. Hackers hold different label such as: black hat hacker and white hat hacker in which all have their own motives.

A computer is secure if you can depend on it and its software to behave as you expect I this assignment I will writer about how Linux provides security to you information. The major technical areas of computer security are usually represented by CIA confidentiality, integrity, and authentication or availability. It means that information cannot access by unauthorized people.

Attack: An assault on the system security that is derived from an intelligent threat. An attack is any action that violated security.

Hacking: Hacking is a type of crime which involves gaining unauthorized access to a computer and changing the system in such a way as to permit continued access without the knowledge or approval of the systems owners.

It is important to be familiar with the sometimes odd terms surrounding computer security. Use your textbook and the Web to look up definitions for the following terms. Write a clear definition for each item using your own language.

A security breach is one of the earliest stages of a security attack by a malicious intruder, such as a hacker, cracker or nefarious application. Security breaches happen when the security policy, procedures and/or system are violated. Depending on the nature of the incident, a security breach can be anything from low-risk to highly critical. In an organization, security breaches are typically monitored, identified and mitigated by a software or hardware firewall. If an intrusion, abnormality or violation is detected, the firewall issues a notification to the network or security

I am Professor Kirk Mooring and I will be your instructor for this class. In this class, you will learn the fundamental core theories of information and network security. In this course, you will learn and use technology skills that are in demand in today’s job market. With so many threats and vulnerabilities created daily that we have to learn to work as a team in order to protect our data with the appropriate security safeguards. You will study the concepts that will help you evaluate and mitigate risk by selecting the appropriate security controls and technologies.

Due to the time restraint and the increasing focus on vulnerabilities in your security structure, this document only covers four of the areas that will eventually have written security policies.

SubBytes—a non-linear substitution step, where each byte is replaced with another according to a lookup table.

With the development of computer technology especial Internet skills, computer has become an important part of human life. On the same time, there are more and more attacks appearing. Hackers attempt to explore the vulnerability of the host to gain unauthorized access privilege and make unauthorized use. However, no all attack can be considered as an incident. Attacks can be classified as incidents only if they meet the following characteristics (Torres, Alissa. Aug, 2014):

To learn more about how most people are defining the terms "security orchestration," "security workflow" and "security automation" in the real world, I decided to

Hacking is the process of gaining unauthorized access to information through various means like systems or computers. In the context of computer security, a hacker is that person who looks for weakness in a system so that they can gain access to unauthorized information. They are motivated by various reasons like protest, profits or evaluating the entire system weaknesses.

Identify and describe the six components of an information system. Which are most directly affected by the study of computer security? Which are most commonly associated with its study?

-The technical definition of computer crimes is an act performed by a knowledgeable computer user, sometimes referred to as a hacker that illegally browse or steals a company 's or individual 's private information, but in general terms, it is the unauthorized use of a computer for personal gain, as in the illegal transfer of funds or to alter the data or property of others (Computer Crime, 2016). There are four major categories of computer crimes, first we will discuss using the computer as a target. When using the computer as a target, they must do two things: intrusion meaning to gain access to the computer and deny the owner of the computer access to the service and data. Intrusion is when the individual alters the data. To use the computer as a target, the hacker must alter the password and/or login and by doing this he is denying the owner access to the data. If a hacker makes a copy of data they are denying the owner rights to privacy of his or her data. The hacker will use that information to intrude upon another computer. One popular method that can be used to deny service is to
