Hey YALL…. Typically, we will always start off informally. So, we can keep it very light when talking about complex topics. We can make it simple and light. Cyber security cover a wide range of sections from packet capturing to root causes analysis, metrics and KPIs.

First and foremost, lest give a little context on cyber security. Just in is basic form, cyber references computers, computer networks, and/or virtual environments. Then when you get into the specifics, you can talk about cybersecurity, which is defending our networks, our devices, and the data from people who shouldn’t have access, cyber-attacks, or from criminal use. It ensures privacy, integrity, and you being able to access your information readily. Cyberspace is to be considered “The virtual world”. It is the interrelated environment that connects all computer networks and the internet. Communication, commerce, and all digital interactions take place in “The virtual world”.  Cyber-attacks are Malice acts by threats actors. Hackers or crime syndicates to just name 2. The purpose of cyber-attacks is to harm, interrupt, or gain unauthorized access to computer systems or computer networks. The last would-be cyber hygiene. Yes, I know cyber hygiene is a thing. Cyber hygiene is simply routine maintenance. Group policy updates, windows updates. Yes, every time your system needs to update, it is highly recommended that you do it.   Multifactor authentication is another form of the concept as well.  

Let’s first talk about the command line. CMD if you see it somewhere. You can access all programs and folders from here. The command line is just the black screen with your host name. and your host name is who you are signed in as on that specific computer. So just two command that you can learn to use on the command line is “hostname” and “gpupdate /force”. The hostname will show on any computer you are signed into. However, group policy update will only show if your computer is connected to an organization. Depending on their policy you may not be able to update your group policy. It could only be done by an employee with administration credentials. Just the surface of executing syntax on the command line is very simple and easy. There are hundreds of commands/syntaxes. Too many to memorize. At any given time, you will only have to use a hand full of them. Most employers will give you a playbook. And a playbook as just the standard operating procedures of the organization. They will list all the syntax that are needed to operate the job efficiently. Every job has a different type of playbook. This is a great question to ask during the employment process.

WireShark is another great tool to utilize to capture network traffic. Wireshark is free, so you don’t have to worry about paying a monthly or annual fee. It is technically called an open-source network packet analyzer. So what Wireshark specifically does is intercept, capture, and decodes current network traffic flowing through your network, breaking it down into a format that is legible to you.
