Cybersecurity refers to the protection of Internet-connected systems from cyber threats. It is used to protect data centers and other computerized systems against unauthorized access. Also known as computer security or information technology security, cybersecurity is important in ensuring sensitive data — whether it belongs to one individual or an entire organization — is properly protected from cyber attacks. Many attackers often aim to hack into your PCs, networks, servers, or mobile devices in order to access, delete, or extort sensitive data stored on such gadgets. As such, it’s vital to always keep your connections secure. This is especially when private data is involved.

As technologies evolve, so do the complexities of cybersecurity mature. However, in contrast, the evolution of technology also provides new methods and approaches to cyber attacks. It’s also worth noting that anyone can be a target of cyber attacks. Whether you are a large corporation or a small organization, you can fall victim to even the most common of cyber attacks. Thus, it’s important to keep your cybersecurity systems up to date to ensure the safety of your data or that of the people around you.

Types of Cyber Attacks

It can be quite a challenge to keep up with new the changes in technology and security. Nevertheless, it’s important to stay updated on the different cyber attacks that can damage you or your business. Educating yourself will help prepare you better for any potential vulnerabilities in your cybersecurity that you may be unaware of. Some of the most common types of cyber attacks include:


Short for ‘malicious software,’ malware is a software that gives any file or program the ability to harm a computer, server, or computer network. Several types of malware exist and can range from computer viruses to Trojan horses. Spyware and adware are also considered forms of malware. Antivirus softwares and firewalls are some common approaches to protecting and preventing malware from infecting your computer.

Password Attack

Simply put, a password attack involves a third party trying to forcefully gain access to a user’s password. A password attack can be particularly harmful, as it can compromise your online accounts. Not only can this lead to stolen identities, but it can also lead to blackmail and even financial exploitation.

Social Engineering

This type of cyber threat relies on using human interaction to trick users into breaking their company’s security procedures. This, in turn, gives the attacker access to confidential information.


Phishing allows attackers to obtain or steal sensitive data by sending fraudulent emails. Often, these fake emails resemble ones that are sent from reputable sources. Thus, the emails can fool users into providing personal data that can be later used to access their accounts. Notably, phishing is similar to social engineering. However, phishing involves more technical trickery — such as fabricated emails — to deceive users.

In order to properly protect your network, it’s important to stay up to date on the different types of cybersecurity. This can help you determine which type works best for you or your line of work. The different types of cybersecurity include the following:

Network Security

Network security protects network traffic by controlling connections. This can help prevent threats from intruding or spreading on your internal networks. By protecting the infrastructure and gaining access to it, network security ensures that your internal networks are secure. In order to flag abnormal traffic and be alerted of threats, the security team uses machine learning to manage network security monitoring.

Network administrators implement policies and procedures so that no unauthorized access, modification, and exploitation of networks can occur. Network security implementations are extra logins, new passwords, application security, antivirus programs, firewalls, and so on.

Cloud Security

Cloud security is a security tool that is software-based. It helps in protecting and monitoring data in your cloud-based services and applications. For enterprise users to better secure their data, new security tools are being created and implemented by cloud providers.

Application Security

Application security is a security measure that involves finding and fixing security vulnerabilities in an application. It uses hardware and software methods to help tackle external threats that can arise in an application’s development stage. Developers make use of application security in order to prevent different threats that may attack their application. Some types of application security are firewalls, encryption programs, antivirus programs, and so on.

Critical Infrastructure Security

Critical infrastructure security can be considered a particularly important form of cybersecurity. It involves the protection of systems and networks that are considered vital in the security of a nation, its people, and its economy. Critical infrastructures include electricity grids, water purification, traffic lights, and hospitals. Cyber attacks that target these systems can cause harm and damage to a society. But, it’s worth noting that many of these systems are not only owned by the private sector, but controlled by this sector as well. This can make it much more challenging to adequately control and update the security required for such infrastructures.

Internet of Things (IoT) Security

The Internet of Things pertains to the integration of Internet connectivity to different digital and mechanical devices. Therefore, IoT security deals with the protection of connected networks and devices in the IoT. Appliances, sensors, televisions, WiFi routers, and printers are some examples of such devices.

It’s worth noting that IoT devices do not have the best of security. This is due to device manufacturers neglecting IoT security. There continues to be a lack of prioritizing for IoT security. As such, IoT devices pose security challenges for their users, as the lack of patching often places them in a state of vulnerability.

Elements of Cybersecurity

Information Security

This involves preventing the loss of sensitive information to illegal sources. It refers to the assurance that personal data will not be lost when issues like system malfunctions, theft, or other critically damaging situations arise.

Network Security

Network security refers to thorough security policies and measures to monitor your network and data. It entails checking through users and granting them access to a network’s data to allow the exchange of information. Users are assigned IDs and passwords, or other forms of authentication, to further enhance a network’s security.

Application Security

Application security involves adding security features in an application, particularly during its development. This can help protect applications and websites from cyber attacks and other security vulnerabilities. Moreover, weak application security can become a point of interference for cyber attacks.
