Cyber security has been a growing issue in recent years. The need for businesses to protect themselves against cyber-attacks has become increasingly important. Businesses can take steps to protect themselves through a number of means, including employee training and using software that detects potential threats before they start.
Phishing is a form of online fraud where attackers send emails or create websites that look like they come from a legitimate company. The messages and sites try to trick people into giving up personal information, such as passwords and credit card details.
Phishers often target large companies because they have access to lots of personal data on their customers, which can be useful for identity theft. They even go so far as to set up fake phone numbers so you think you’re calling the real company’s customer service line—but it’s actually just a phishing scammer trying to steal your credentials.
Malware is a general term for any software used to disrupt computer operations, gather sensitive information, or gain access to private computer systems. Malware includes computer viruses, worms, Trojan horses, ransomware, and spyware.
A virus is a program that can replicate itself and spread from one system to another without user intervention. A worm spreads itself over the Internet by exploiting security holes in operating systems like Windows or Linux. The most famous of these types of malware was the Morris worm created by Robert Tappan Morris at Cornell University in 1988.
This program caused massive disruption on the Internet when it was released into the wild and infected thousands of computers connected to the internet at that time.
A Trojan horse (or just “trojan”) is a program that appears harmless but hides malicious functionality so as not to be detected by antivirus software. Ransomware is malware that encrypts files on an infected computer and then demands payment for them to be decrypted. Spyware records keystrokes or other activity on infected computers so it can retrieve sensitive information such as passwords and credit card numbers.
Let’s take a closer look at what makes up a virus:
• It is a program that can replicate itself and spread from one computer to another.
• It is designed to spread from one computer to another.
Viruses are programs that spread themselves by attaching themselves to other programs or files, or by directly attacking your computer’s operating system (Windows, Mac OS X, and Linux). Viruses can also be introduced into your system via external media such as floppy disks, CDs, or USB drives.
Ransomware is a type of malware that infects a computer, encrypts its data, and restricts access to it until a ransom is paid. The word “ransom” refers to the demand made by the attacker for money in exchange for unlocking the system. Ransomware attacks may be carried out using file-encrypting ransomware or logic bomb ransomware. They may also be propagated via any kind of media: on infected websites, through spam email attachments (usually PDF documents), or by exploiting security vulnerabilities in browsers.
A URL (uniform resource locator) is the unique address of a page on the internet. The URL format includes a protocol, such as http:// or https://, followed by the hostname and optionally other information that identifies the specific page you want to view.
• Protocol: This is a standard way for computers to communicate over the Internet—for example, HTTP stands for HyperText Transfer Protocol. When you open a website like this one in your browser (e.g., Chrome), your browser will automatically start connecting with that website using its protocol (http://). You can also see where this connection takes place by looking at your address bar; it’ll say something like “http://www.cybersecurityagencyofamerica”.
• Hostname: This part of an Internet address tells you where exactly on the internet you’re going—like if I said “google” instead of “www.” That would tell me where exactly I was going without having to look at my address bar! For example, if my friend sent me an email saying “let’s meet up at Starbucks” their email might look like this: @gmail. That Gmail thing means they’re sending it through Google’s email service called Gmail so we know which account we should expect emails from and what sort of server recognizes them as valid accounts when logging into websites etcetera…
A Trojan horse is a program that appears harmless but is actually used to gain access to your computer and steal information.
A Trojan horse can be downloaded from the Internet, but it can also be hidden on a Flash Disk or external hard drive. Sometimes a Trojan horse will be disguised as an email attachment, so if you ever receive an email claiming to be from someone in your address book and asking for personal information (such as passwords), don’t open the attachment!
Cyber security is a very important topic and one that should be taken seriously. It can affect everyone no matter what their profession or interests are. The best way to protect yourself is by always being cautious when it comes to emails, links, and attachments.
