TechGYD | What is Cybersecurity? Definition and What you Need to Know About it

Many businesses and individuals are using the internet today to transact their business. This is evolving cyber threat at an alarming rate, with an increasing number of data violations every year. As a result, the majority of the companies are increasing their spending on cybersecurity protection to deal with the rising cyber threats. So, what is cybersecurity? Read on to know more.

Cybersecurity is a practice that involves different techniques to protect data, servers, computers, mobile devices, networks, and electronic systems, from unauthorized access or malicious attacks. Cybersecurity protection practices should be put into practice by big and small organizations, workers, and individuals too. Among the most challenging parts of cybersecurity is the continuously developing nature of security risks as well as the advanced continual threats.

What is cybersecurity? Types of cybersecurity threats

Some of the most common methods that are used to threaten cybersecurity include:

Ransomware

This is a form of malware whereby an attacker locks the computer system files of the victim generally through encryption. The attacker then demands a fee to decrypt and also to unlock them.

Malware

Malware is a type of malicious software wherein any program or file can be used to damage a computer user, like computer viruses, worms, spyware Trojan, and horses.

Social engineering

Social engineering is an attack which relies on human contact to trick the users into breaking the security procedures to get sensitive information which is protected.

Phishing

This is a type of fraud whereby false emails are sent, and these emails resemble those from trustworthy sources. The purpose of these emails is, however, to steal sensitive information, like login or credit card information.

Importance of cybersecurity

Cybersecurity is critical since it helps to protect the data assets of an individual or organization from digital attacks. These attacks can result in significant damage if (when) the data lands in the wrong hands. Security incidents might lead to considerable losses in terms of theft of data, erased  data, fraud, and even reputation. Everybody relies on vital infrastructure such as hospitals, financial service companies, power plants and others. These organizations usually collect and store large amounts of data on their computers and other devices too. Protecting the data of these organizations' is crucial in keeping our society working.

What does cybersecurity prevent?

Cybersecurity helps to prevent identity theft, data breaches, as well as ransomware attacks. It also aids in risk management. When a business has stable network security along with an efficient incident response plan, it is suitable for it to be capable of preventing and mitigating cyberattacks. The practice of keeping up with the new technologies, threat intelligence, and security trends is a demanding task for any organization and individual too.

The risks of having poor cybersecurity

There are lots of risks, and some of the risks are more serious. Among the risks is malware deleting your whole system, an attacker gaining access into your system and altering with your data, or an attacker stealing your credit card data and making illegal purchases. Though there might be no assurance that even with the most extraordinary safety measures, several of these things won't occur to you, there are, however, some steps you can take to reduce the chances.

Elements of cybersecurity

Network Security

Network security involves protecting the integrity, safety of all networks that are associated with your data. By securing the network from potential threats, the attacker gets blocked when trying to access any content from that particular network.  Network security measures include the use of antivirus, anti-spam, and other similar applications. Firewall blocks all unauthorized entry into the system, while a particular configured virtual private network (VPN) is used to access the network in a secure way remotely.

Cloud security

This is a software-based tool which monitors and protects your data in the cloud, so as to help reduce the risks that are related to on-premises attacks

Data loss prevention: 

This entails developing processes and policies for managing and preventing data loss as well as developing recovery strategies in case of a cybersecurity infringement. This incorporates setting network authorization and systems for storing data.

Application security: 

It uses software and hardware to protect against outside threats, which might present themselves in the development stage of an application. Some of the examples of application security are firewalls, encryption, and antivirus programs.

End-user education: 

What is cybersecurity in end-user education? This entails teaching the users how to follow the best practices such as discouraging clicking of unknown links or downloading uncertain attachments in emails. Suspicious attachments and unknown links might allow in malware along with other malicious software. 

Cybersecurity is continuously being challenged by hackers, privacy, risk management, data loss, and the altering of cybersecurity protection policies. There is nothing that currently shows that cyberattacks will lessen soon. Besides, with the high number of access points for attacks, additional strategies for protecting digital assets are required to protect devices and networks. Individuals and organizations should know what is cybersecurity and how helpful it is.
