Cybersecurity means the measures taken to protect a computer or computer system (as on the internet) against unauthorized access. This is how Merriam Webster dictionary defines it.
To make it even more simple for you, Cybersecurity involves techniques that help in securing various digital components, networks, databases, and computer systems from unauthorized access or cyber-attacks from hackers.
1. What is a Cyber Attack?
A cyber attack means the techniques used by hackers with the intention of stealing or causing harm in any way to various digital components, networks, databases, and computer systems.
2. What is the importance of Cybersecurity?
With the highly increasing rate of the utility of digital assets in various fields of daily life, there is also a highly increased rate of threat to such digital assets in the form of different types of cyber attacks. These cyber attacks can cause financial losses and destroy the privacy of people and even the most confidential data of the state can be stolen. The only solution to all these matters is to employ the best cybersecurity techniques.
3. What is the purpose of Cybersecurity?
The sole purpose of Cybersecurity is privacy, anonymity, and protection against different types of cyber threats.
Privacy means you are living in your home and people know that you are in your home but they don’t know what you are doing in your home.
Anonymity means your identity is completely hidden and nobody knows who is doing that specific thing because it could be anyone.
Cyber threats mean any kind of threat to our digital assets in any form.
4. What are the 6 different types of Cybersecurity?
Cybersecurity can be further classified into different types and the success of a Cybersecurity system strategy depends greatly on the collaboration between all these types. Following are the 6 different types of Cybersecurity:
- Application Security
- Information Security
- Disaster Recovery
- Network Security
- Website Security
- End-point Security
You can learn in detail about all these types of Cybersecurity from another article of mine here.
5. What is an asset in Cybersecurity?
In Cybersecurity all those digital things are assets that you value the most and which you want to protect e.g. photos, videos, confidential files, etc.
6. How does Cybersecurity work?
It works by applying a strategy accompanying some of the best practices to protect our assets.
You can never have 100% security of your assets neither you can have a 0% risk of threats because even going on the internet is a risk and moving forward in your life is accompanied by many risks. So, we need to take a risk-based approach to apply the right type of security. Practices like installing a firewall, implementation of honey pots, and adopting difficult alphanumeric passwords, etc. could be a part of a Cybersecurity strategy.
7. What are the different elements of Cybersecurity?
There are the following 9 elements of Cybersecurity:
8. What are the different types of Cybersecurity threats?
There are the following types of Cybersecurity threats:
Malware means all the programs that are written with malicious intent to either steal confidential data or disrupt the privacy of a person, organization, or even a state.
2) Macro Viruses:
These are the viruses that are written in macro languages like VBS/VBA that are mainly platform independent and they could be embedded into word documents.
3) Stealth Viruses:
They usually try to hide any modifications made and try to trick the antivirus software by providing false and bogus information.
4) Polymorphic Viruses:
It produces varied operational copies of itself and such a virus may have no paths that remain identical between infections that make it very difficult to detect directly using signatures in antivirus software
5) Self-Garbling Viruses:
They work by attempting to hide from antiviruses by modifying their code that does not match pre-defined antivirus signatures.
6) Bots and Zombies:
That are a collection of hacked devices under a commandant control of a hacker. So, if your machine just get compromised it could be a part of a bot network or been a zombie.
These are viruses that simply spread from one machine to another.
Rootkits are the worst software-based malware that you can get as they are usually embedded in the kernel of the operating system and it can hide its existence completely from the operating system.
9) Firmware Rootkits:
These are worst of all type of malware. They can exist in the firmware chip of your hard drive and even formatting the hard drive or reinstalling the operating system won’t fix it.
10) Key Loggers:
They do as they sound and they actually log your key strokes.
11) Trojan Horses:
These are actually programs that appear to be one thing but they are actually malware. For example, you download a software and it acts as one but at the back it’s also a malware.
12) Remote Access Tools(RAT):
These are malicious programs that run on your system and allow intruders to access your system remotely and it is like TeamViewer for the hacker.
It is actually a malware taking control of your pc in some way and then behind the scenes covertly encrypt all your personal files with a decryption key only the hacker knows.
It is an online advertisement that is infected with virus or malware.
15) Drive-by attacks:
It is strange name given to simply visiting a website that contains code that can actually exploit your machine.
As the name suggests its main purpose is to gather information and send it back to the attacker but to spy the attackers don’t generally want to cause damage directly but want to compromise your privacy and anonymity based on some agenda they have got.
They can take control of your search engine even and the browser also and start forcing to show adds and defends itself against attempts to remove it.
It is a type of social engineering attack to trick a person into believing in a threat that isn’t really real.
19) Potentially Unwanted Programs (PUPs):
PUPs are applications that have legitimate uses but have functions and behaviors that can be exploited against the user without the user’s consent.
Phishing is a type of attack that typically attempts to trick the victim into clicking on a link or executing malwares someway and it can be an attempt to compromise a device to steal some sensitive information, passwords, usernames, pins, credit card numbers, as well as try to gain access to online accounts.
21) Vishing and SMShing:
Vishing and SMShing are both forms of Phishing. Vishing is basically a voice form of Phishing and SMShing is SMS Phishing or sending Text messages. So, this is an attempt to call or text you in order to compromise your device in the same way as you do with phishing.
9. What are the benefits of Cybersecurity
There are the following main benefits of Cybersecurity:
- Protection for businesses against different cyber threats.
- Security of digital assets.
- An effective Cybersecurity strategy can help build a secure environment which ultimately increases confidence and trust in a company.
- An encrypted conversation b/w two officials of a company help in keeping the privacy and confidentiality of the private matters of a business or a company.
- Having properly adopted a Cybersecurity strategy is like going outside wearing a bulletproof jacket. It is so powerful that it can even protect an entirely digital environment from almost any kind of cyber attack.
10. What are Top Cybersecurity Challenges?
There are the following top Cybersecurity challenges:
- Protection against the advanced types of malware
- Protection against different kinds of viruses

- Contrast Security
- Digital Guardian
- Cofense Triage
12. Awareness of Cybersecurity
We all spend most of our time on the internet via different devices and it won’t be wrong to say that in some way we are all dependent on the internet and so are prone to hundreds of Cyber threats.
All of us should have at least a basic knowledge about cybersecurity and some basic practices that could help us in taking preventive measures against various cyber threats.
13. What are Cybersecurity Risks?
In Cybersecurity, risks are the calculation of the probability of happening of an event and the amount of loss caused by that event.
14. Who needs Cybersecurity?
There are now written programs and automatic bots available for attacking vulnerable software without needing human beings to waste their valuable time.
We often face hacking attacks online sometimes in the form of emails, websites, malware, etc. As users, we want better and better technology, and the more we rely on it the more complex it becomes and thus gets more prone to cyber threats.
So, all of us need Cybersecurity to some degree in order to protect our privacy, businesses, and confidential data.
15. Is it hard to study Cybersecurity?
