CYBER SECURITY AND THEIR THREATS

Cybercrime is defined as any unauthorized activity involving a computer, device, or network. There are three generally recognized classifications of cybercrime: computer-assisted crimes, crimes where the computer itself is a target, and crimes where the computer is incidental to the crime rather than directly related.Here is a list of common cyber threats:

• Cyberterrorism: This threat is a politically-based attack on computers and information technology to cause harm and create widespread social disruption.
• Malware: This threat encompasses ransomware, spyware, viruses, and worms. It can install harmful software, block access to your computer resources, disrupt the system, or covertly transmit information from your data storage.
• Trojans: Like the legendary Trojan Horse of mythology, this attack tricks users into thinking they’re opening a harmless file. Instead, once the trojan is in place, it attacks the system, typically establishing a backdoor that allows access to cybercriminals.
• Botnets: This especially hideous attack involves large-scale cyberattacks conducted by remotely controlled malware-infected devices. Think of it as a string of computers under the control of one coordinating cybercriminal. What’s worse, compromised computers become part of the botnet system.
• Adware: This threat is a form of malware. It’s often called advertisement-supported software. The adware virus is a potentially unwanted program (PUP) installed without your permission and automatically generates unwanted online advertisements.
• SQL injection: A Structured Query Language attack inserts malicious code into a SQL-using server.
• Phishing: Hackers use false communications, especially e-mail, to fool the recipient into opening it and following instructions that typically ask for personal information. Some phishing attacks also install malware. 

• Man-in-the-middle attack: MITM attacks involve hackers inserting themselves into a two-person online transaction. Once in, the hackers can filter and steal desired data. MITM attacks often happen on unsecure public Wi-Fi networks.
• Denial of Service: DoS is a cyber attack that floods a network or computer with an overwhelming amount of “handshake” processes, effectively overloading the system and making it incapable of responding to user requests.

As data breaches, hacking, and cybercrime reach new heights, companies increasingly rely on cyber security experts to identify potential threats and protect valuable data. So it makes sense that the cyber security market is expected to grow from $217 billion in 2021 to $345 billion by 2026, posting a Compound Annual Growth Rate (CAGR) of 9.7% from 2021 to 2026.
