In the realm of cybersecurity, these terms help describe different stages and levels of potential harm to an organization's digital assets:

Security Threat

A security threat is an intentional act that compromises the confidentiality, integrity, or availability of information security threat to an organization's data, systems, or operations. These acts are usually malicious, including attempts to steal sensitive data or information, corrupt data, disrupt services, or gain unauthorized access.

Security Event

A security event is an occurrence that might indicate a potential security breach or compromise. It refers to any observable action or behavior that could affect the security of an organization's digital environment. Events could include unauthorized remote access or attempts, unusual patterns of network traffic, or suspicious user behavior.

Security Incident

A security incident is a confirmed occurrence with unauthorized access, disclosure, alteration, or destruction of the data that breaches an organization's data or information systems. In other words, it's a breach in security that has resulted in actual harm or compromise.

As cybersecurity threats become more advanced and sophisticated, organizations must constantly be vigilant to safeguard their critical data and networks. To effectively protect company data against these threats, enterprise IT teams must understand the dangers and potential attack vectors they might encounter.

This awareness and understanding enable them to implement appropriate security measures, strategies, and technologies to mitigate risks and ensure their digital assets' safety and network security.

Security Threats That Can Gain Access To Your Business Information

Insider Threats

An insider threat happens when someone already part of an organization, like an employee, contractor, or even a partner, uses their unique access to the entire organization's systems and data to do something harmful. This harm can be done intentionally, like stealing vital information, or accidentally, like making a mistake that causes a big problem.

Cyber Threats

Cybersecurity threats are attempts by malicious individuals or groups to gain unauthorized access to data, disrupt digital operations, or cause damage to information. These threats can come from different sources, including various threat actors with other motives.

For example, some corporate spies might try to steal valuable business secrets, hacktivists who use hacking as a form of protest or activism, terrorist groups, nation-states engaging in cyber espionage or cyber warfare, criminal organizations seeking financial gain, individual hackers, government agencies and even disgruntled employees who have insider knowledge.

Malware (Malicious Software) Attacks

Malware, a term used to describe malicious software, encompasses a variety of harmful programs like spyware, ransomware, viruses, and worms. When triggered, the malware takes action through a user's interaction, such as clicking on a harmful link or attachment, resulting in the installation of dangerous software. Once activated, malware has the potential to:

  1. Block Access: Ransomware, for instance, can restrict entry to crucial network components.
  2. Install Harmful Software: Malware might introduce more damaging software onto the affected system.
  3. Covert Data Retrieval: Spyware, a type of malware, can secretly collect information by sending data from the device's hard drive.
  4. Disrupt Operations: Some malware strains can disrupt system components, rendering the system inoperable.

Viruses and Worms

Worms and viruses are harmful malware that target an organization's computer systems and data. A computer virus replicates by copying itself into other files, while a worm spreads independently, often using automatic system functions.

Once activated, both can cause widespread damage by infecting other computers operating systems and networks. It's crucial to have robust cybersecurity measures to defend against these threats.


Phishing attacks employ deceptive communication, often in emails, intending to deceive the recipient into opening the message and following the enclosed instructions. These instructions can involve actions like sharing a credit card number.

The intention behind phishing is to either extract valuable data such as credit card details and login credentials or to introduce malicious software onto the victim's device. Here you can find excellent cybersecurity professionals and solutions for businesses.


Smishing is similar to phishing but operates through SMS (text messages) rather than email. In smishing attacks, the attacker pretends to be trustworthy and sends deceptive messages to mobile devices. The goal is to trick recipients into revealing sensitive information.

The attacker can access the web if these compromised mobile devices are connected to a company network. This leads to customer and other data access, business email compromise, employee data theft, and potential exposure to an organization's source code. It's essential to be cautious of smishing attempts to protect personal and company information.

Man-in-the-middle (MITM) attacks

Man-in-the-middle (MITM) attacks are a type of cyber threat. In these attacks, an unauthorized individual intercepts and possibly alters the communication between two parties who believe they are directly communicating with each other. The attacker positions themselves between the two parties, essentially eavesdropping on the transmission without the parties' knowledge.

This technique enables the attacker to potentially steal sensitive information, such as login credentials, financial data, or other confidential information being exchanged between the parties. MITM attacks can occur in various scenarios, including public Wi-Fi networks or compromised cloud storage systems.


A botnet attack is a type of cyber attack that exploits a botnet, which is a network of compromised computers and devices, all controlled by a single entity called the "bot-herder." These compromised machines, also known as bots, are connected to perform coordinated actions on a large scale.

Cybercriminals utilize botnet attacks for various purposes, such as aggressive web scraping, Distributed Denial of Service (DDoS) attacks, and other extensive cybercrimes. In a botnet attack, the bot-herder can issue commands to all the infected devices from a central point, causing them to engage in criminal activities simultaneously.

The term "botnet" comes from "robot network," where each infected machine acts like a robot under the attacker's control. The bot-herder can modify the infected devices' behavior remotely, allowing them to adapt to changing circumstances or carry out new attacks. This flexibility and scale enable botnet attacks to be highly effective and damaging.

Due to the potential of these attacks, bot-herders can even rent out segments of their botnet on the black market for financial gain. Individuals and organizations must take measures to prevent their devices from becoming part of a botnet and to implement cybersecurity practices to protect against these attacks.

DDoS (Distributed denial-of-service) attacks

A Distributed Denial-of-Service (DDoS) attack is a type of cyber attack where the attacker overwhelms a server or network with a massive volume of internet traffic. This attack aims to disrupt the normal functioning of the target server or computer network, rendering it unavailable to users trying to access online services or websites.

In a DDoS attack, the attacker uses a network of compromised computers, a botnet, to flood the target with enormous traffic. This surge in traffic makes it extremely difficult for the server to handle legitimate user requests, effectively denying access to the services.

The term "Distributed" in DDoS signifies that the attack comes from multiple sources, making mitigating even more challenging. DDoS attacks can have significant impacts, causing websites and online services to become slow or completely inaccessible to users. Organizations need robust cybersecurity measures to detect and mitigate DDoS attacks to ensure their services remain available to legitimate users.

Weak Password Attacks

Weak password attacks involve exploiting passwords that are easy to guess or crack. These passwords are typically short, standard, default (as set by the system), or easily thought through brute force attacks.

Brute force attacks involve trying all possible password combinations until the correct one is found. In the case of weak passwords, hackers can use techniques like using words from the dictionary, common names, variations based on the user's name, or easily guessed themes. These weak passwords become an easy target for cybercriminals who can sell compromised information on the dark web or use it to launch more attacks.

Even more sophisticated versions of attacks involve dictionary attacks. These attacks leverage our tendency to use common words as passwords. Hackers compile lists of these common words into "cracking dictionaries" and use them to guess passwords. Additionally, they might personalize attacks by using words personally significant to the user, such as birthplaces, children's names, or pet names.

It's crucial to use strong, unique passwords for user accounts and consider multi-factor authentication to bolster the security of online accounts and protect against these types of attacks.


In a ransomware attack, cybercriminals use malicious software (malware) to carry out various harmful actions like encrypting, deleting, or manipulating data and intellectual property or personal information. Ransomware is malware that aims to steal information or prevent a user or organization from accessing their files.

Both actions are achieved by encrypting the files on the victim's computer and demanding a ransom payment for the decryption key. The attackers lock the victim's files and demand payment to unlock them. This puts the targeted organization or individual in a difficult position, often leading them to consider paying the ransom as the quickest and most cost-effective way to regain access to their files.

Ransomware operators often use phishing emails and social engineering to initiate attacks. They might send deceptive emails that trick recipients into clicking on malicious links. The ransomware is introduced onto their device once the victim clicks such a malicious link.

Preventing ransomware attacks requires a combination of robust cybersecurity practices, employee training to recognize phishing attempts, and keeping software up to date to minimize vulnerabilities that attackers might exploit.

Domain Name System (DNS) attack

DNS, which stands for Domain Name System, is a crucial part of how the internet works, translating human-friendly domain names into IP addresses that computers can understand. DNS attacks exploit weaknesses in this system to carry out malicious actions.

A DNS attack involves cybercriminals exploiting vulnerabilities within a server's Domain Name System. This system's primary role is to convert user-provided domain names into IP addresses through a DNS resolver. In a DNS attack, the attacker compromises a DNS server by substituting a valid IP address in the server's cache with a fraudulent one. This alteration redirects traffic to a malicious website, where the attacker can collect information or initiate further attacks.

Cache poisoning, or DNS poisoning, is a DNS attack where attackers manipulate the DNS cache to associate legitimate domain names with incorrect IP addresses, redirecting users to malicious sites.

In addition to these attacks, there are Denial of Service (DOS) attacks, which are intended to disrupt the availability of a network or website by overwhelming it with a flood of traffic.

Preventing DNS attacks requires implementing security measures such as using secure DNS resolvers, regularly updating DNS software, and monitoring suspicious DNS behavior.

Drive-by download attacks

A drive-by download attack is a cyberattack in which malicious code is downloaded and executed on a target device without the user's awareness or consent. This attack is commonly used to install and distribute various types of malware, including worms, trojans, and ransomware.

Specifically, drive-by download attacks involve installing malicious programs on a user's device without their explicit permission or knowledge. These attacks can lead to unintentional downloads of files or bundled software onto a computer or mobile device.

A user might visit a compromised website, and in the background, malicious code is downloaded and executed on their device without any visible indication.

Zero-Day Attacks

A zero-day attack occurs when hackers take advantage of a software vulnerability before the developers or vendors know it. The term "zero-day" signifies that the developers have just learned about the flaw and have "zero days" to fix it before the attack occurs.

When cybercriminals exploit a vulnerability on the day it's discovered ("day zero"), it minimizes the chances that an organization can detect and respond to malicious attacks effectively. Security measures and updates must still be implemented to address the newly discovered vulnerability. The attackers use this window of opportunity to compromise systems or steal sensitive customer data anyway.

Protecting against zero-day attacks requires a proactive approach to cybersecurity, including regular software updates, intrusion detection systems, and other security measures that can help identify and mitigate unknown system vulnerabilities before they are exploited.

IoT (Internet of Things) attacks

An IoT attack targets vulnerabilities in internet-connected devices, like smart home gadgets, industrial systems, or medical devices. Attackers can take control, steal data, or use devices maliciously, like forming botnets.

Critical differences from IT attacks:

1. Attack Surface: IoT devices lack robust security features due to limited resources, making them easier to exploit than traditional IT systems.

2. Diverse Devices: IoT devices vary in type, OS, and connectivity, complicating standardized and security controls.

3. Physical Impact: Unlike most IT attacks on data or services, ioT attacks can harm critical infrastructure or life-dependent systems.

4. Legacy Devices: Older IoT devices without updates are vulnerable to cyber attacks, a rarity in traditional IT.
