  • Last Updated : 09 Mar, 2021

Cyber Security is the practice of Protecting computers, mobile devices, Servers, electronic Systems, networks, and data from malicious attacks. It’s also known as Information Security (INFOSEC) or Information Assurance (IA), System Security. Cyber Security is important because the government, Corporate, medical organizations collect, military, financial, process, and store the unpreceded amount of data on a computer and other property, personal information, or exposure could have negative consequences. 

Cyber Security proper began in 1972 with a research project on ARPANET (The Advanced Research Projects Agency Network), a precursor to the internet. ARPANET developed protocols for remote computer networking. Example – If we shop from any online shopping website and shared information like email id, address, and credit card details as well as saved on that website to enable a faster and hassle-free shopping experience then the required information is stored in server one day we receive an email which state that the eligibility for a special discount voucher from XXXXX (hacker use famous website Name like Flipkart, Amazon etc.) website in order to receive the coupon code, and we will be asked to fill the details then we will use saved card account credentials. Then our data will be shared because we think it was just an account for the verification step then they can wipe a substantial amount of money from our account. 

That is why Cyber Security provides Service as a Security Gate-Way to make information more Secure, in today’s time hackers are advance we can’t surely say the data store in my Devices is safe or not by outside threats. With Cybercrime increasing at a rapid pace, it’s crucial to have Cyber Security in place of personal life and our Business.

The importance and challenges of Cyber Security :
Cyber security is important in any organization no matter how big or small is the organization. Due to increasing technology and increasing software across various sectors like government, education, hospitals etc., the information is becoming digital through wireless communication networks. 
The importance of cyber security is to secure our data of various organizations like email, yahoo, etc. which have extremely sensitive information that can cause damage to both our reputation. Attackers target both small and large companies and obtain their important documents and information. 
There are few reasons why it is important which are as follows:

  1. Cyber security is on rising –
    There are 4000 roughly cyber attacks every day. One of the reasons why cyber crime is increasing is because it is cheap, fast, and highly profitable compared to other types of crime which is why cyber criminals are headed.
  2. Damage is significant –

    Cybersecurity affects trust with customers and employees.  When people feel that their information is being properly secured and kept private. They began to lose trust in the brand the product, and the services.
  4. Our identities protect our data –
    User identity now protects billions of points of data. This is the data we are transmitting at work data from the internet of things, devices or a coffee maker or the printers we use and our personal information as more of our data is becoming digitized. Security of these identities helps to reduce the risk of cybercrime to organizations and to individuals alike.
  5. Every organization has vulnerabilities – 
    As organizations evolve, merge, and grow over time their networks and systems naturally get more complicated and things may slip through the cracks. Additionally, end-users can often be the weakest link in an organization’s security, and that requires the organizations to put robust security and compliance protection in place. We should all care about cybersecurity.

  5. Phishing
  6. Denial of service
  7. Privilege escalations
  8. Unpatched/Vulnerable software
