What is Cybersecurity? [In-Depth Explanation]

cybersecurity, what is cybersecurity

Cybersecurity simply means the protection of Internet-connected systems from cyber threats. It is used to protect data centers and other computerized systems against unauthorized access. Cybersecurity helps in protecting or providing good security positions from possible attackers with bad intentions for your PCs, networks, servers, mobile devices (or cell phones), and data stored on these gadgets.

Cybersecurity is important in ensuring user’s or organization’s sensitive data are properly protected from cyber attacks designed to access, delete, or extort them. It experiences changes with the advancement of technologies on a regular basis, thereby creating new ways for cyber attacks. Security breaches are what get published regularly. Small organizations also have to be bothered about their security being breached since they’d be the target of viruses and phishing.

As technologies evolve, organizations and services should ensure they implement cybersecurity tools, training, risk management approaches, and continually update systems so as to ensure the safety of organizations, employees, and individuals.

Types of Cyber Threats

It can be quite a challenge to keep up with new technologies, security trends, and threat intelligence can be a really challenging task but it is important in protecting information and other assets from different cyber threats. Types of cyber threats include:


This is a form of malicious software that gives any file or program the ability to harm a computer user. Malicious software such as computer viruses, Trojan horses, spyware, keyloggers, and so on.

Ransomware attack

This cyber threat involves the attacker locking or encrypting the files of his victim’s computer system and then demanding a ransom to decrypt or unlock the files.

Social Engineering

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


This is a way of obtaining or stealing sensitive data by sending fraudulent emails that resemble emails sent from reputable sources. The attacker can as well use phone calls and text messages to obtain those sensitive data. Some of these sensitive data that can be obtained are credit card or login details.

Types of Cybersecurity

Network Security

Network security protects network traffic by controlling connections to 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 alert 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 would 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 everyone must have to help protect their computer systems. Software and hardware methods are used by application security to help tackle external threats that can arise in an application’s development stage. During the development phase, the adoption of security measures is an imperative phase of the project since applications are more accessible over networks. Some types of application security are firewalls, encryption programs, antivirus programs, and so on.

Critical Infrastructure Security

Critical Infrastructure Security comprises cyber physical systems that are relied on by modern societies. When an electricity grid’s infrastructure is on the internet, it will be vulnerable to cyber attacks. Organizations responsible for critical infrastructures are to perform with diligence and understand the vulnerabilities and also try their best to protect their business against those vulnerabilities. This critical infrastructure’s security and resilience are vital for the safety and well-being of our society. Even organizations that are not responsible for the security of any critical infrastructure but still rely on it for part of their business must develop a contingency plan on how an attack on the critical infrastructure they depend on would directly affect them. The critical infrastructures include electricity grid, water purification, traffic lights, hospitals, shopping centers, and so on.

Internet of Things (IoT) Security

Internet of Things Security deals with different critical and non-critical cyber-physical systems. Appliances, sensors, televisions, WiFi routers, and printers are some of the cyber-physical systems. The core technology of the internet of things security market is the Internet of Things data center, consumer devices, networks, legacy embedded systems, and connectors. The Internet of Things devices poses a unique security challenge for its users since they are frequently sent in a vulnerable state and also offer barely any security patching.

Elements of Cybersecurity

Information Security

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

Network Security

Network security refers to thorough security policies and measures adopted by a network administrator to frustrate and monitor illegal access, intentional misuse of service for a computer host, and other interaction related resources. It entails checkmating the freelage rights of users and granting them cyber access to the network’s data and allow the exchange of information. Users are assigned ID and password or other forms of authentication to further enhance cyber security and entry of unauthorized domains.

Application Security

This involves steps rolled in an information application protocol to halt any attempts to bypass authorization limits set by the security policies of the basic system. Applications are concerned with dictating the use of resources allotted to them. The designated use of resources is decided via application users through application security.

End-User Education

This is the weakest link that has to be trained properly to lessen its vulnerability to cyber attacks. Regular end-user education and reviews are essential to underscore system vulnerabilities to cyber threats and computer security loopholes to the user.

Why is Cybersecurity Important?

Increase of IoT

A lot of smart devices are connected to the internet. These are known as the Internet of Things (IoT) devices and they are increasingly common in homes and offices. Normally, these devices can simplify tasks, they can offer the desired level of control on our environment. Their proliferation presents a problem.

If not handled properly, each IoT device that is connected to the internet can open a pathway to cyber threats leading to cyber attacks with a way into a business. With the use of IoT devices introducing a wide range of Computer security weaknesses, it is wise to conduct imperative vulnerability checks to help address risks presented by these devices.

Increase In Available Hacking Tools

The vast availability of hacking tools and programs on the internet means there is also a growing threat from individuals. The ill dividends of cyber attacks have made it easy for anyone to obtain the resources they need to launch damaging attacks on cybersecurity.

Rising Cost Of Breaches

Being a cybersecurity breach can cause customers to lose trust in a business. Having a reputation for poor cybersecurity can also lead to a failure to win new business.

Advantages of Cybersecurity

Cybersecurity comprises lots of plus points. Just like the term says, it offers security to the system or network and it is popularly known that keeping things secure has numerous advantages. Some cybersecurity benefits are:

Security Organization

Cybersecurity revolves around securing an organizations’ networks from external attacks. It helps ensure that the organization performs really well and feels safe about its important data.

Safeguarding Sensitive Data

Cybersecurity helps to protect sensitive data like patient data, student data, sales data, and so on from unauthorized access so that it wouldn’t be misused.

Hamper unauthorized access

It helps shield the system from being accessed by an unauthorized person. The data can be fetched by only authenticated users and is securely kept.

Ensuring Data Reliability

Data or information from organizations protected by cybersecurity are known to be highly reliable and can be utilized without the slightest hesitation.

Cybersecurity Challenges

Cyber Securities tend to get challenged regularly by cyber attackers, hackers, loss of data, breach of privacy, risk management, and the continuous changes in cybersecurity. Although nothing currently shows that the rate of cyberattacks will decrease, with the increase in cyber attacks the more cybersecurity you would be needing to secure networks and devices. Some cybersecurity challenges are:

Continually Evolving Nature of Security Risks

With the emergence of new technologies and the different ways in which they’re being used, new ways for cyber attacks are being developed too. With the new changes and advances in cyber attacks as well as updating their practices can be pretty hard or challenging to keep up with the new changes. This means that cybersecurity elements should be regularly changed and updated to protect against potential vulnerabilities. This whole process can be truly challenging for small organizations.

Cybercriminals Stealing Personal Information

Organizations today tend to gather a lot of potential data on individuals that take part in their services. The more data these organizations collect, the more vulnerable they are to attacks by cybercriminals who would want to steal personally identifiable information. For instance, an organization that stores personally identifiable information of their clients in the cloud would likely be subjected to attack by ransomware, and they should try to find a way to protect their cloud from being breached.

End-user Education

Another challenge is end-user education. If employees are not given the right orientation or educated on cybersecurity, they would accidentally bring viruses into their work computer, laptop, or smartphone.

Job Shortage

Job shortage is another cybersecurity challenge. As development in data from organizations turns out to be progressively significant, the requirement for more cybersecurity personnel to analyze, oversee, and respond to incidents increases. It is estimated that there are 2,000,000 vacant cybersecurity jobs around the world. Cybersecurity Ventures also gave an estimation on the vacancy rate in cybersecurity and according to their estimations, by 2021 there will be up to 3.5 million vacancies. To help in arranging and overseeing data, the new advances in Artificial Intelligence (AI) and machine learning are developed.

Cybersecurity Vendors

Cybersecurity vendors use the endpoint, network, and developed security measures for protection against threats and prevention of loss of data. Cisco, McAfee, and Trend Micro are the top three notable cybersecurity vendors.

Cisco’s main focus is on the network and it permits its clients to use firewalls, VPNs, and advanced malware protection alongside supporting email and endpoint security. Real-time malware blocking is supported by Cisco.

McAfee ensures that they produce cybersecurity products for their consumers and enterprise users. They offer services like data protection and encryption.

Trend Micro deals on anti-malware offering services for protection from cyber threats for systems like mobile, hybrid clouds, SaaS, and the IoT. Trend Micro offers to its user’s endpoint, email, and web security.
