We’re connected to the web 24/7 and we’re becoming more and more dependent on the internet. Almost everything we do in our daily lives is in one way or another related to the internet. So, online security should also become a major part of our lives. Cyber security is crucial in data protection as it protects devices and networks from unauthorized access or attack.

Individuals, businesses, and governments need to invest in cyber security services to protect themselves and their clients from outside attacks. Everyone should understand cyber security, its importance, and what you can do to protect yourself online. 

Let’s start with this guide on the importance of cyber security in the digital age. 

What is Cyber Security?

Cyber security is the act of protecting online information by minimizing information risks and vulnerabilities. Common cyber security issues include unauthorized access to data, use of data, disclosure, interception, or destruction of data. 

Protecting personal information and data online is absolutely crucial in today’s time. Especially because the volume and the severity of cyber attacks are constantly increasing. 

Online security practices help in securing data and sensitive information from outside threats. 

Importance of Cyber Security in Today’s Age

It is almost impossible to ignore the importance of Cyber-Security in today’s time. As everything is connected, a single attack can have huge consequences. The 2017 Equifax data breach exposed personal information of 145+ million individuals. The 2018 Marriott breach exposed information of 500+ million individuals. 

Not just the loss of personal data, it also leads to huge financial losses. Moreover, it impacts the customer's trust level in big organizations. Therefore, Cyber Security is essential to keep businesses and individuals safe from hackers.

Key Components of Cyber Security

For data protection and online security, every business needs to follow some basic steps. Here are some things businesses can keep in mind while building a cyber security plan:

#1. Network Security

Focus on firewalls, intrusion detection and prevention systems, and other measures to protect organizations from external threats.

#2. Data Encryption

Encrypting data protects it from falling in the wrong hands even if the network is somehow breached. Protecting sensitive information such as customer information and financial records should be a business’s priority.

#3. Endpoint Protection

Online attackers often use endpoints to enter a system. Endpoints are devices connected to an organization’s network, such as laptops, computers, mobile devices, and more. 

Protecting these devices and the network with an additional layer of security is a great way to prevent data breaches. 

#4. Incident Response

Even if you have the best cyber security measures in place, it is possible to run into these attacks every now and then. Having a clear and robust incident response plan in place can help you with data recovery protocols. 

#5. Staying Vigilant

Nothing works better in online security than staying vigilant. Train your employees to look out for possible spam emails, fake links, and other suspicious online activities.

Plus, make sure your organizational cybersecurity plan is up to date and has all the latest protocols in place. 

Importance of Cyber Security for Businesses

The importance of cyber security for businesses is to protect against data breach. Data breaches can potentially bankrupt a business. One of the biggest reasons to implement a cyber security plan is to protect against data breaches. 

One of the most severe data breach examples in today’s time is WannaCry ransomware attack, which attacked businesses and organizations globally. This attack resulted in the loss of data and money for a lot of organizations. Some businesses even had to shut down.

Importance of Cyber Security in Banking

One of the biggest reasons why cyber security is important in cyber security is the breach of 2014 of JPMorgan Chase. During this breach, hackers stole personal identifiable data such as names, addresses, phone numbers, and email addresses of 76 million households and 7 million small businesses. 

That’s not all, hackers also gained access to account information, including account numbers and balances, or 83+ million JPMorgan customers. 

For customer and business data protection, cyber security is of utmost importance in the banking sector. If account information and personal information falls into the wrong hands, it can be catastrophic.

Most Common Types of Cyber Attacks

Cyber attacks have grown exponentially in recent years and their flow doesn’t seem to be stopping any time soon. Cyber attacks leave a devastating impact on businesses and individuals.

Theft of social security numbers, bank accounts, and personal information can leave an individual broken. Storing data on cloud services such as Dropbox or Google Drive is one of the biggest reasons why data gets hacked. 

Some of the most common cyber attacks include:

1. Phishing Attacks

Phishing is a type of cyber attack that involves tricking users into clicking on malicious links or attachments. Clicking on such links can lead to the theft of sensitive information, such as login credentials or financial data. 

1. Malware Attacks

Malware is basically a type of software that can infect computers and devices. Some software can even stop the device from working completely. The goal of a malware is to steal personal information, hijack devices, or launch an attack on the entire system. 

1. Denial-of-service Attacks

A denial-of-service attack is a type of attack that prevents users from accessing a software or a service. This is done by overloading the system with traffic or requests or damaging it so the device doesn’t work properly.

1. Ransomware Attacks

Ransomware is a malware that encrypts files or systems and demands a ransom to fix the device. It can lead to the loss of crucial data, or the entire system shutting down completely.

1. SQL Injection

A SQL Injection is a special type of cyber attack, in which a hacker exploits vulnerabilities in a web app and injects malicious SQL code into the database.

This code can view, delete, or modify data in the database. SQL injections can take over servers and also carry out other malicious activities.

How Individuals Can Protect Themselves Against Cybercrime

Protecting personal information online has become a part of our lives. Most individuals don’t know how to protect their information online. So, here are some tips to try out.

#1. Use Strong Password

Almost every password should be at least 8 characters long and include a mix of uppercase and lowercase letters, numbers, and symbols. Avoid using words like your name, your pet’s name, your date of birth, etc.

#2. Use a Password Manager

If you think keeping track of all these complicated and different passwords is a chore, then using a password manager can be a great option. Some password managers not only store your passwords, they can also generate strong passwords for you.

#3. Don’t Reuse Passwords

Reusing passwords is one of the worst ways to protect multiple accounts. If a hacker gains access to one account, they gain access to all your accounts. 

#4. Keep Your Software Up-To-Date

Software updates often include security patches that help user information and user data. 

#5. Use Multi-Factor Authentication

Two-Factor Authentication adds an additional layer of security to all the accounts. Even if a hacker gains access to your accounts, they won’t be able to log in as you’ll receive a one time password to access the account. 

#6. Be Vigilant About Phishing Emails

Phishing emails are one of the biggest ways scams happen today. Scammers act as a legitimate company and send you emails to try and get you to divulge your personal information. 

FAQs

Q. What is cybersecurity?
