2. Blockchain in Cyber Security
• Maintaining the security of online data is crucial as more and more
individuals use the Internet for daily activities and routines.
• Due to centralized network , the current internet infrastructure is vulnerable
to cyber attacks, which causes fraud and data theft.
• Blockchain is the best option for enhancing cyber security across business
and safeguarding our data
Primary categories of cyber security-
• Application security
• Cloud security
• Network security
• Critical infrastructure security
• IoT security
3. Cont..
Most frequent types of cyberattacks-
• Cross-site scripting attack
• Phishing attack
• Denial if service attack(DoS), DDoS
• Ransomeware attack
• Man-in Niddle attack
Challenges in cybersecurity-
• Preventing data theft
• False data entry prevention
• Protecting centralized data
4. Cont..
Cybersecurity using Blockchain-
• The three fundamental characteristics of blockchain that help to avoid
cyber attacks are that they are trustless system, immutable and have
network consensus.
• Consensus mechanism like proof of work make sure that even if this
occurs, the network will still carry out its intended duties without human
interferrence.
• Any attempt to tamper with blockchain database would be detected and
stopped by network consensus
• Blockchain offers decentralize security and distribute digital information
• Blockchain technology can be used to stop cybercrimes like identity theft,
fraud and data theft.
