Almost everything we are doing today is happening on the internet. Sometimes we take help from Google for making our college projects, we chat with friends on the internet or in our free time, we just scroll on the social media apps. While the internet is making our lives easier, it also brings some risks and that’s where cyber security comes in. Cybersecurity is the process of protecting systems, networks, and programs from digital attacks or unauthorized access.
Let’s discuss more about cyber security, like what it is, and what are the different types of cyber security? Also, we will take a short discussion over the different types of cyber threats.
What Is Cyber Security?
Cybersecurity is the process of protecting the device’s data and networks from things like online attackers, hackers, viruses and online scams. It is like putting up a strong lock on your online activities so that nobody can invade your privacy and see your data.
It is not like setting up any kind of antivirus software on your laptop, but it is more than that, it is about taking important steps to ensure that your stuff, like your passwords, photos, and even school assignments, stays safe from people who want to steal or mess with it.

What Are The Different Types Of Cyber Security?
Now that we know what cybersecurity is, let’s now know what are the different types of cyber security: –
1. Application Security
Application security is about making sure the apps are developed in a way that prevents hackers from exploiting any security. For instance, there is a bug or gap in the app’s code so that hackers could sneak in. Application security works to stop that by using encryption, and regular updates, so that when you are using your banking app or you are logging into an online class, you can trust the application to protect your data.
2. Cloud Security
Cloud security is about keeping your data safe in the cloud. It ensures that no one can steal your data. It scrambles your files so that only you can read them, and by making sure you log in securely with things like a password and a code sent to your phone. So, when you are saving your assignments or important notes in Google Drive or iCloud, cloud security is making sure no one else can get to them.
3. Critical Infrastructure Security
Our lives are deeply reliant on electricity, water, and transportation, and so these are called the critical infrastructure. The Critical infrastructure security is about keeping these important systems safe from hackers and different kinds of digital damage. It ensures that these important services stay updated and keep running smoothly. It is like putting a security system on the most important parts of a country or city’s infrastructure to keep them safe from cyber threats.
4. Data Security
Data security keeps the information safe from any kind of stealing or hacking, to secure data it uses encryption (means locking your data in a secret box so that only you can open it) firewalls (it is a digital wall stops unwanted visitors) and secure backups so that you don’t lose your important data. For instance, when we use any UPI app to transfer money online, the data security ensures that no one can sneak into your details.
5. Endpoint Security
To perform our daily tasks, we use many electronic gadgets like phones, laptops, tablets, these devices are known as endpoints because they are the end points with which we connect to the internet. Endpoint security work to keep all these devices safe from threats like malware, viruses, and hackers. Also, it uses antivirus software, firewalls and regular updates to keep everything protected.
6. Iot (Internet Of Things) Security
Now we have experienced many smart gadgets like smart speakers, fitness trackers, smart bulbs, and even Amazon’s Alexa, which all come under the Internet of Things (IoT). While these devices make our lives easier, they also need protection. IoT security protects these things from any kind of hacking. It puts security locks on all smart gadgets in your home, so that no one can invade the data.
7. Mobile Security
Mobile phones are part of our lives, from checking emails and social media to mobile banking, our phones use a lot of personal data. Now you probably have understood that mobile security is all about making sure your phone stays safe from hackers, viruses, and any other threats. It includes things like strong passwords, enabling fingerprints or face recognition and installing apps from trusted sources.
8. Network Security
Every single time when we use the internet, we connect to a network. Network security protects the network from unauthorized access, data breaches and attacks. It uses firewalls, encryption, and other tools to keep everything safe and makes sure that your data is protected while it’s being transferred.
9. Operational Security
Operational security, also known as OpSec, talks about how you handle your information every day. Which methods do you use to protect your sensitive data so that it doesn’t fall into the wrong hands? To help you protect your data, it involves things like choosing strong passwords, not sharing your account details and being alert about your every click. In short, it forges little habits in you to protect your important information safely even when you are just doing normal stuff.
10. Zero Trust
Zero trust simply says “Never trust anyone even if they are inside the network”. With Zero Trust, every time someone inside the company or an outsider tries to access the system, they must prove they are legit. This uses things like multi-factor authentication (MFA), instead of trusting everyone automatically, it keeps verifying that the access by an individual is authentic. Zero Trust ensures there’s no free access, and everything stays secure.
11. Identity And Access Management (IAM)
Identity and Access Management (IAM) is like a gatekeeper who checks your ID every time you need access to something important just to make sure only authorized people can get it. It also includes things like strong passwords, biometrics and multi-factor authentication. For example, when you log in to the student portal to check your grades, it asks for roll number and password just to ensure that only you can access your personal information.
12. Penetration Testing
Penetration testing, also known as ethical hacking, is when a penetration tester acts like a hacker to find weaknesses in a system before the real hackers can exploit it. They use the same methods as cybercriminals use to get into systems, but they do it with permission. They identify weaknesses like weak passwords or outdated software and fix them before they can be used unlawfully.
What Are The Different Types Of Cyber Threats?
- Malware: Malicious software designed to harm your device or steal data.
- Phishing: Fake attempts to steal personal information by pretending to be a trusted source.
- Ransomware: A type of malware that locks or encrypts files and demands payment to unlock them.
- Denial-of-Service (DoS): Overloading a system or network with traffic, making it crash and stop functioning.
- Man-in-the-Middle (MitM): Intercepting communication between two parties to steal or alter the data.
- SQL Injection: Injecting malicious code into a website’s database to steal or manipulate data.
- Password Attacks: Attempts to guess or steal your password to access accounts.
- Social Engineering: Manipulating people into sharing confidential information, often through psychological tricks.
- Advanced Persistent Threats (APTs): Long-term, targeted cyberattacks where hackers infiltrate systems to steal information or disrupt operations, often remaining undetected for a long time.
- Zero-Day Exploits: Attacking a software vulnerability that is unknown to the software maker, so there’s no patch available yet.
