Network Security - Business and Personal

-

 

            Network security is important not only for businesses and organizations, but for individuals, as well. According to Vahid & Lysecky, over 178 million records were exposed due to security breaches in 2017, roughly 1.5 billion data breaches, and the cost in the US caused by cybercrime in 2016 was 1.3 billion dollars. Cybercrimes pose a very real threat to companies and individuals across the world. Companies and individuals must practice safety when using the internet, like changing passwords frequently, installing firewalls for personal and business servers to block unwanted traffic, and using the least amount of information necessary when entering personal information online.

            Information travels throughout the world via networks. The internet is a global network of information. Using ping methods or trace routs, a user can follow the path of the packets of information across the network. The information leaves a footprint along the way through each point in the network, making the information vulnerable to cyberattacks from various points in the network (Vahid & Lysecky 8). If the network is vulnerable, this could cause security holes that allow malicious hackers to steal private information or hack accounts.

            Spam is a form of unsolicited information being sent to users in large quantities. Awati points out, though, that spam is often sent through botnets and not by actual humans (2023). Spam mail is usually sent out with financial motivation and intended to persuade readers to purchase goods or services. While most users delete spam, there is a small percentage of people that still follow through with the junk mail and will make a purchase.

            Phishing is another form of hacking, usually through email. However, as technology progresses scammers are using phone, video, and text-messaging to attempt to “phish” for information (Palmer 2023). Phishing generally entails tricking a user into entering their personal information, like logins and passwords, into a site that the user believes is a trustworthy website. Phishing can occur with large organizations and individuals, and everyone needs to be aware of what to look for when opening emails that are from unknown users.

            Checking for the name of the website in the address is one easy way to make sure that websites are legitimate. Hackers will often make spelling mistakes or errors. Also, if being asked to log in to an account, a user could go directly to the website themselves instead of using the link in the email. Phishing can be detrimental to someone’s personal information and should always be kept in mind when opening emails.

Employee Management System - Simple Project

  The employee management system project is designed to take user input and store the information as variables for later use. As Miller, Vahid, and Lysecky point out, a variable “is used to remember a value for later use" (2015). Creating the variables of employeeName, employeeSSN, employeePhone, employeeEmail, and employeeSalary were to hold the information to display later in the program. Variable types were string with the exception of the salary input that was set as an integer.             Repetition was very useful in writing this code. Each line was the same just changing the variable name and type in the string. Employee salary was the only line that had an addition with the sep= function to remove the space after the $ sign in the code. This was used for appearance purposes. Setting the variables to strings allowed the user to enter dashes if needed and parenthesis if desired for the phone number. Setting the variabl...

Explicit and Implicit Variables

-
  What is a Variable? Using implicit or explicit variables is an important decision when choosing what language to use when writing a program or starting to code. In simplest terms, a variable is used to remember a value for later use. The way different programming languages use variables is important for programmers to keep in mind when choosing how to code variables. Implicit variables are when the compiler chooses the type of output and explicit variables are when the programmer pre-assigns variables to have a specific output. Examples of Variables Each can be useful depending on the program that is being written. Boudreau points out that implicit variables can often be easier to use in programming and that sometimes the results can be just fine. However, leaving the compiler making that decision making on an assumption can often lead to problems. Explicit assigning of variables gives a more specific output and result and can be much more reliable. Depending on the lan...

Creating Tables in MySQL

  Creating Tables in MySQL           Creating tables in MySQL is important so that a user can add information, delete information, and update an entry using SQL statements. Also, a final statement was created to join all three tables demonstrating the relationships between the three tables. The INSERT function was used to add rows to the first table named tbldvdtitles. The information was inserted and the code and the results are pictured below: MySQL instructions were used by Oracle to guide the use of MySQL. The next table was a table called tbldvdActors with the information inserted and results below: Updating and deleting rows were part of the requirements for the interactive assignment and the following code was used: A third table was created to describe the relationships between actor ID and the ASIN number for each movie and the results were as follows: Joining all three tables was the last step and the results were as follo...
