How blockchain helps to reduce cybercrimes ?

As the world goes online and people relays on the Internet for their routine processes and habits, it is essential to maintain the security of online data. Blockchain, a notable buzzword of recent days has taken charges to secure online data.

Cyber Security - What is it?

Cyber Security is the collections of techniques or methods to protect computers, data, coding, and networks,etc., from access or attack by unauthorized sources. Cyber Security is also known as Information Technology Security or Computer Security that protects data or information.

In short, the protection against the theft of data in computers and the Internet is termed as Cyber Security.

Cyber Criminals: A person who commits cybercrimes ie., using a computer or online medium as a tool and target to steal data.

Cyber Crime: A process of hacking that involves computer or internet.

Types of Cyber Security

The major types of cybersecurity involve the following
1. Cloud security
2. Application security
3. Critical infrastructure security
4. Internet of things (IoT) security
5. Network security and so on.

Major Cyber Attacks

The most common types of cyber attacks that happen often are as follows:
1. Phishing attacks
2. Cross-site scripting (XSS) attack
3. Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks and a lot more.

Challenges in Cyber Security

1. Protecting centralized Data
As data is stored in a centralized medium, it becomes a big challenge for cyber security industry to protect all the data from hackers.
2. Preventing Data Theft
Current cyber security faces a lack of trust among business individuals as it finds much difficult to prevent data theft.
3. False Data Entry Prevention
As storage is centralized, it requires many verification steps by the human to prevent false data entry or data modifications.
4.  Dos and DDoS attacks
Prevention of major cyber attacks namely, DoS and DDoS attacks on business data by hackers becomes a tedious process for cyber security industry.
5. Serverless Apps Vulnerability
Server-less applications can be a way for cyber attacks to happen which is also sometimes beyond the control of cyber security.

There are also some other challenges of that cyber security finds hard to overcome which involves Ransomware, malicious applications and lot more.

Blockchain In Cyber Security

Blockchain is a booming technology that boosts every business and industry verticals. As the count of cybercriminals increases complex and are endlessly trying to steal valuable data like financial data, health records, intellectual property, and personal identifiable information, so on.

So, Blockchain could potentially enhance cyber-defense that prevent fraudulent activities through consensus mechanisms and detect data theft depending on utilizing its characteristics such as data encryption, auditability, operational resilience, immutability, and transparency.
