What is cyber security?

Cyber Security

Cyber security measures are designed to combat threats against networked systems and applications, whether those threats originate from inside or outside of an organization. You know today’s world is all about computerized work or the digital world whether we shop online, make payments online, or book any tickets. Government companies or the public sector also do everything online nowadays. Even they make payments online with the help of the Internet and some applications. It means all types of data are transferred here and there.

People become smart nowadays due to these advanced technologies available in the market but it is also important to keep the data safe because there are many frauds, hacking, virus attack, and data theft happening in the market. People should secure their data and it is very important to secure your data before you face any loss. So, anyone can secure their data with the help of cyber security.

Cyber Means

Cyber means anything related to the internet, information, applications, technology, computer, networks, data, etc. and security means the safety of anything related to system security, application security, network security, information security, etc., Cyber Security secures the data, information, networks in computer systems. 

Let’s understand what is cyber security and how it works with the help of an example –

There’s one girl named Harshita who wants to shop online. She usually shops from Amazon or Urbanic sites. She has information like email id, home address, mobile number, and credit or debit card details saved on the website so she can easily do shopping every time without putting the same details, again and again, every time she shops and she will experience faster and hassle-free shopping.

All information is stored on a server. One day, she received an email in which she receives a special discount voucher from a shopping cart she has to fulfill all details that are required for eligibility for a special discount voucher. To receive that code, she asked to fill out some account credentials. She thought that it was just an account verification process but then she realized that a huge amount of her account has been debited from her account.

So, what do you think that how this happened? Yes, the email she received was fake. This process is known as a cyberattack in which a third party (unauthorized access) has all the details and the person who did all this is known as a hacker. 

She can save herself from this all fraud or fake email messages with help of cyber security. Cyber Security secures all the data, information, and network in computers.  It is a technique that secures digital networks, data, and computer systems from all unauthorized access. There are many techniques to apply to cyber security. It just depends on what kind of network you are connected to and the type of cyber attacks in which you suffer losses. 

Now let’s see an example of how she can save herself from a cyber attack with the help of cyber security. 

She installed a firewall in which the firewall filters the incoming and outgoing traffic from your device and safeguards your network. It can be a software application. And then implemented honey pots which are used to attract attackers. In addition, she can also put unique alphanumeric passwords to use antivirus software. Then started avoiding emails from unknown senders.

Many big companies/organizations or people face lots of money loss due to these cyber-attacks but since then cyber security has come, and there’s not that much loss of people or companies’ money. There’s improvement in the digital market in many ways and people can save themselves from the loss because of cyber-attacks with the help of cyber security.

Types of Cyber-Attacks-

  1. Malware Attacks-
    • Malware attacks are one type of malicious software. It causes damage to any computer, server, or network without end-user knowledge. It’s had many types like viruses, trojans, ransomware, etc.
  1. Phishing Attacks-
    • In phishing attacks, hackers send fraudulent emails to anyone. This is done to install malware or to steal data like credit or debit card information and login credentials. 
  1. Man-in-the-middle Attacks-
    • Here the hackers gain access to the information path between anyone’s devices and their websites (which usually they use). The hackers try to take over the IP addresses and the website intercepted them. This can be happening because of an unsecured Wi-Fi network and can be through malware too.
  1. Password Attacks-
    • This is the easiest attack anyone can do. Anyone’s password can be cracked or tried by using common passwords like ABC123.So, this is the most common type of cyber-attack people are facing nowadays. You must be thinking that which companies provide security against it.

Now let’s discuss the name of big companies which provide security against cyber-attacks-

  1. AppTrana – This company provides services like web application firewall, web application scanning, mobile application scanning, etc.
  1. Perimeter 81 – This company provides services like zero-trust network access, networking monitoring, and management, VPN alternative, etc.
  1. Checkpoint Software – This company provides services like network security management, endpoint security, etc.
  1. CISCO – This company provides services like Firewalls, Malware protection, Email security, multi-factor authentication, etc.
  1. Cipher CIS – This company provides services like Managed Security Services, Managed Detection, and Response, Cyber Technology Integration, Governance Risk and Compliance, etc.

So, this is a list of just a few companies who do their best every day to provide security against cyber attacks and the annual turnover of all these companies is millions of dollars. Now you must be thinking about those countries where cyber security is strong. 

Well, China is ranked number one in providing the best cyber security services. And the second one is Netherlands and France. And then the united states and Canada also provide the best cyber security services. But India is not the best in providing cyber security services as compared to other countries so India needs to update its cyber security and here’s why?

  • As you know, India has become a digitalization India. People in India do everything online nowadays and there’s also fraud everywhere. There are lots of benefits to digitalization but in India, many people take benefit of it and do fraud with other people. So, there’s a need for very strong cyber security to stop these all things. 
  • In India, there are many people like billions who are non-education and semi-skilled workers. Hackers know how to make these people crazy(pagal) and transfer all amounts to themselves. India is a shortage of cyber security professionals so people in India need to learn about it deeply and also how to save from any losses. So those who are planning to do a course in cyber security then please learn it as much as you can, this is the correct time to switch your professional. You can save billions of people from losses.
  •  India has used outdated software for so many years. India doesn’t have strong links provided to people. They are ignoring it due to cost issues and they do not understand that if you use outdated software, then there will be a loss of billions of rupees and ruin of business systems.  If data is not secure, then obviously many people take benefit from it. So, it is necessary to use updated software and provide very strong links to people.
  • Even the Government of India does not feel safe about data and networks because smart people can do fraud with them too. India needs to invest in research and development (R&D), and develop skills for the Internet of Things (IoT) and security. This will not only help protect citizens or govt from cyber-attacks but there will be an improvement in the economy too and investors will invest in India.

  3. Thanks for the suggestions you have discussed here. On top of that, I believe there are several factors that keep your motor insurance premium down. One is, to consider buying cars and trucks that are within the good listing of car insurance organizations. Cars that happen to be expensive tend to be more at risk of being snatched. Aside from that insurance is also in accordance with the value of your car, so the more expensive it is, then higher this premium you spend.

  5. I have learned a number of important things as a result of your post. I’d personally also like to say that there may be a situation where you will apply for a loan and do not need a cosigner such as a National Student Support Loan. But when you are getting that loan through a classic finance company then you need to be made ready to have a co-signer ready to assist you to. The lenders will certainly base their very own decision over a few factors but the main one will be your credit ratings. There are some lenders that will in addition look at your work history and decide based on this but in many instances it will depend on your score.
