In 2023, go over the fundamentals of cyber security with students


The world of cybersecurity is growing quickly as a result of new technology and rising data demand. You can find out how students can learn about this field in the article that follows. To assist people comprehend what cyber security is and why it is crucial, it provides some concrete instances. Some people think that the topic of cyber security is highly technical and obscure. However, you must be aware of the value of being well-versed in the field of information technology because if you don’t understand what cyber security is and why it is so important for your company or organisation, you risk falling behind more advanced businesses and people who make use of these technological advancements. Understanding cyber security necessitates knowing not just what it is but also why it is crucially important. Password protection, computer system encryption, firewalls, access control methods, intrusion detection systems (IDS), antivirus software, malware detection, and many other topics will be covered. We hope that this article gave you a head start.

In addition, I gained another category of knowledge known as “basic facts and definitions.” These explanations give details on terms like “hacking,” “phishing,” “identity theft,” “fraud,” and many others. They must to assist students in thoroughly comprehending the fundamentals of cyber security.

Why Do People Hack?

When someone tries to do anything improper or “out of place,” they typically utilise an assailant. American mathematician Frank Jelinek initially used this phrase while working at MIT. “If a guy has a secret key, he may break into any number of organisations and cause trouble,” he said. Any device, including PCs, laptops, cellphones, tablets, etc., can be hacked at any time in a given workplace. By preventing the hacking of their online accounts, users may defend themselves from hackers. Hackers can assume the identities of companies, websites, or other people in order to access a company’s or an individual’s data. Strong passwords can help with this. Even if you constantly change your passwords, hackers will still find you and try to steal your credentials before anybody else can enter your private site. Logging into your account with a stolen password is one way to accomplish this. What should you do if someone emails you requesting that you sign them up for an account but you already have your own login details? If you start to feel uneasy, look over our comprehensive guide to social engineering.

What Exactly Is Phishing?

An attack is one that uses phishing. They may be people you’ve heard of previously. Unfortunately, not everyone is aware of what this means. A message purporting to be from the holder of a specific email address appears to be sent by an actual person. Your acquaintance sent you an email stating that they had forgotten their password for your email account. In any case, if you read the email and click the link, you would be selling all of your private information. You will be immediately redirected to the hacker’s website if you click the link. In exchange for your details and/or banking password, they will offer you money or something of value. This method of deceiving people into providing their financial information and credit card data is very popular today. Additionally, this con artist will probably gain access to your bank data. They would attempt to verify your ownership of this website as soon as you provide your login and password, and then send an email to an authorised bank requesting your consent to open an account in your name. Unless you are taken by surprise, there is no reason to panic. Although the FBI cautions against responding to spam emails, occasionally getting such texts can lead users to believe that they are communicating with a legitimate email account. After you open the attachment, hackers will elicit information from you, like your Social Security number, birthdate, and birthday, in order to steal your customer or personal information. However, as you are obtaining the answers, the hacker may already be planning where to put everything so that, if you’re lucky, they may sell it for more money or gather more data on your Facebook and Twitter activities. Remember: Never divulge your private bank or credit card details out of politeness. Never open any attachments that contain links like the ones below, either.

I trust you now have a clearer understanding of what hacking and phishing are. Don’t touch the button once you see emails with harmful attachments. Even if the sender identifies themselves as a friend via an unidentified contact, don’t respond to anything. Simply ignore it entirely and move on to the following email.

Passwords: How Do Criminals Use Them?

Everyone uses a laptop or desktop computer to communicate in the modern world. The majority of work and communication is done through computer programmes called software applications. Software engineers are skilled at creating safe algorithms and programmes that defend against malicious attacks. Therefore, it is strongly advised that each user instal security software programmes such as antivirus, antispyware, firewalls, VPN, security cameras, Internet browsing blockers, password managers, virus scanners, etc. on their computers and other electronic devices. For instance, Microsoft Windows 10 offers the choice to enable virus and spyware protection on your computer, smartphone, tablet, and online browser. Many companies and consumers choose to purchase goods with integrated security apps and programmes. They also add additional levels of security to keep their private information safe while using the internet. Employees also utilise digital assets like Apple Pay cards, Google Wallets, PayPal, Amazon Pay, Bitcoin payments, the Nando’s mobile app, the Shopify payment gateway, the Samsung Pay wallet, PayPal, Zelle transfers, the iTunes and Spotify mobile music players, Adobe Photoshop, Evernote notes and screenshots, etc. Passwords, credit card information, medical records, and other sensitive information are all stored on all of these devices. Each user must utilise the best password manager and passcode generator tool to safeguard these details. Remember that weak passwords are simple to exploit and lose. You must therefore retain a copy of the same password in backup form in several locations. If you have a physical device with a USB drive, for instance. Make sure to create a disc image backup of it. Having a backup drive means that nobody else will ever have access to this material! Because this kind of vulnerability is now seen as a severe problem, you should always retain your backups.

Various Attacks

One or more of the aforementioned attack types may have happened to you. The truth, however, goes beyond that. Let me discuss a few actual events so you may have a better idea of the kinds of crimes hackers are capable of committing. One out of every seven breaches of personal data, according to the U.S. Department of Justice, involved password failures. Therefore, it is crucial for all enterprises to use authentication and encrypted files to secure their networks. It is not sufficient to only demand secure passwords. Regular audits and verification of the current operating system version are equally important.

Users Are Involved in Negligent Activities (Threatening Viruses, Fraudulent Phishing URLs, Stealing Information From Organizations)


Malware is typically developed automatically and without your input. Malware can appear anywhere, from your web browser’s start screen to a background activity. Once turned on, they may have a variety of effects on your online experience. Here are a few examples of malware from several categories:

Web scraping: Pop-up ads from unauthorised sources are shown on a website or web page. It can be a URL that contains data from your browser’s cookies. This website downloads and runs a piece of code whenever you visit it. It’s possible that the malware has infected your device every time you attempt to close it. The likelihood that you may experience this issue is great if your browsers have not been updated. Another risk is if you unintentionally save the downloaded file or copy it to your clipboard without taking into account the possibility that it contains malicious software. vulnerable OSes It may be anything, from Linux-powered servers to older operating systems like Windows 95. Misconfigured server ports, weak network connections, unsafe Wi-Fi connections, and slow download speeds are further possible issues. Hackers frequently construct websites where they post stuff meant to pass for original because there are no updates for internet security standards and technologies. The most recent danger has raised a number of concerns about the reliability of websites and web pages. Attackers have full access to the victim’s personal information when they use this type of website, and they can place orders or make transactions without the victim’s knowledge. False QR Codes — In places where QR codes aren’t accepted, fake QR codes are frequently used. A reader can scan any part of the screen while scanning the code. These codes can have false images or wrong text printed on them. User experience issues – Your website may have issues with UX, design, and loading times. Users may quit your website as soon as they can if your user interface or user experience is poorly done. Data loss – Given the number of parties engaged in the transaction, hackers frequently get access to the server and instal malicious software, such as ransomware, on the victim’s computer. Users’ information is locked by ransomware for days or weeks. Attacks on a distributed denial of service (DDoS) are frequently carried out by bots or hackers who take advantage of the network infrastructure already in place. As a result of each bot spreading its own traffic over the network,
