Cyber Security :-

Cyber Security का अर्थ है Computers, Networks, Mobile Devices, Applications और Digital Data को Unauthorized Access, Attack, Damage, Theft और Misuse से सुरक्षित रखना।

आज के समय में Banking, Education, Healthcare, Business, Government और Personal Communication जैसे लगभग सभी क्षेत्रों में Digital Technology का उपयोग होता है। इसलिए Digital Systems और Data की Security बहुत महत्वपूर्ण है।

Cyber Security का मुख्य उद्देश्य Data और Computer Systems की Confidentiality, Integrity और Availability को बनाए रखना है।

1. Confidentiality (गोपनीयता)

Confidentiality का अर्थ है कि Information को केवल Authorized Person ही Access कर सके।

उदाहरण:

Bank Account की Information केवल Account Holder और Authorized Bank Employees को ही Access करनी चाहिए।

Confidentiality का उद्देश्य → Unauthorized Access को रोकना।

Confidentiality के लिए उपाय

  • Password – Account और Data को Unauthorized Access से बचाने के लिए।
  • Encryption – Data को एक unreadable form में बदलने के लिए।
  • Access Control – यह निर्धारित करने के लिए कि कौन-सा User किस Data को Access कर सकता है।
  • Authentication – User की Identity को Verify करने के लिए।
  • Multi-Factor Authentication (MFA) – User की Identity Verify करने के लिए एक से अधिक Authentication Methods का उपयोग।

2. Integrity (अखंडता)

Integrity का अर्थ है कि Data Accurate, Complete और Unchanged रहे और उसमें Unauthorized Modification न हो।

उदाहरण:

अगर किसी Bank Account में ₹10,000 Balance है और किसी Unauthorized व्यक्ति द्वारा इसे ₹1,00,000 कर दिया जाता है, तो Data Integrity प्रभावित हुई है।

Integrity का उद्देश्य → Data को Unauthorized Modification से बचाना।

Integrity के लिए उपाय

  • Hashing – Data में हुए Changes को Detect करने के लिए।
  • Digital Signature – Data की Authenticity और Integrity को Verify करने के लिए।
  • Access Control – Unauthorized Users को Data Modify करने से रोकने के लिए।
  • Data Validation – Data को Valid और Correct Format में सुनिश्चित करने के लिए।

3. Availability (उपलब्धता)

Availability का अर्थ है कि Authorized Users को आवश्यक समय पर Information और Services उपलब्ध रहें।

उदाहरण:

अगर Banking Website का Server Attack के कारण बंद हो जाए और Customers Banking Service को Access न कर सकें, तो Availability प्रभावित हुई है।

Availability का उद्देश्य → Authorized Users को Data और Services उपलब्ध रखना।

Availability के लिए उपाय

  • Backup – Data की Extra Copy रखना ताकि Data Loss होने पर उसे Restore किया जा सके।
  • Disaster Recovery – Disaster या Major Failure के बाद System को Recover करने की प्रक्रिया।
  • Redundant Systems – Primary System Fail होने पर Backup या Alternative System का उपयोग।
  • Regular Maintenance – Systems को Regularly Update और Maintain करना।
  • DDoS Protection – DDoS Attacks से Server और Online Services को सुरक्षित रखना।

🔐 Cyber Security :- In English

Cyber Security means protecting Computers, Networks, Mobile Devices, Applications and Digital Data from Unauthorized Access, Attacks, Damage, Theft and Misuse.

Today, Digital Technology is used in almost every field such as Banking, Education, Healthcare, Business, Government and Personal Communication. Therefore, the security of Digital Systems and Data is very important.

The main objective of Cyber Security is to maintain the Confidentiality, Integrity and Availability of Data and Computer Systems.

1. Confidentiality

Confidentiality means that Information should be accessed only by an Authorized Person.

Example:

Bank Account information should be accessed only by the Account Holder and Authorized Bank Employees.

Objective of Confidentiality → To prevent Unauthorized Access.

Measures for Confidentiality

  • Password – Used to protect Accounts and Data from Unauthorized Access.
  • Encryption – Used to convert Data into an unreadable form.
  • Access Control – Determines which User can Access which Data.
  • Authentication – Used to Verify the Identity of a User.
  • Multi-Factor Authentication (MFA) – Uses more than one Authentication Method to Verify the User's Identity.

2. Integrity

Integrity means that Data remains Accurate, Complete and Unchanged and is not subjected to Unauthorized Modification.

Example:

If a Bank Account has a balance of ₹10,000 and an Unauthorized Person changes it to ₹1,00,000, then Data Integrity has been affected.

Objective of Integrity → To protect Data from Unauthorized Modification.

Measures for Integrity

  • Hashing – Used to Detect Changes made to Data.
  • Digital Signature – Used to Verify the Authenticity and Integrity of Data.
  • Access Control – Prevents Unauthorized Users from Modifying Data.
  • Data Validation – Ensures that Data is Valid and in the Correct Format.

3. Availability

Availability means that Information and Services should remain available to Authorized Users whenever required.

Example:

If a Banking Website's Server goes down due to an Attack and Customers cannot Access Banking Services, then Availability has been affected.

Objective of Availability → To keep Data and Services available to Authorized Users.

Measures for Availability

  • Backup – Keeping an Extra Copy of Data so that it can be Restored in case of Data Loss.
  • Disaster Recovery – The process of Recovering a System after a Disaster or Major Failure.
  • Redundant Systems – Using Backup or Alternative Systems when the Primary System fails.
  • Regular Maintenance – Regularly Updating and Maintaining Systems.
  • DDoS Protection – Protecting Servers and Online Services from DDoS Attacks.
