Internet users are vulnerable and exposed to different online threats. Many users are prone to cyber attacks each day. Cybersecurity has become one of the most important aspects at the moment. A group known as OurMine hacked HBO’s social media accounts and leaked unwatched episode of Game of Thrones Season 7. This is a major blow for the satellite TV network. Recently HBO was hacked by another group, hackers entered HBO’s servers and browsed through its internal documents and unreleased TV shows.
Hackers who name themselves “Mr Smith Group” have also threatened to leak the finale of Game of Thrones Season 7 before its air date after they released HBO social media passwords. The group is demanding a huge payout amounting to $6.5 million as ransom. On the other hand, reports from the Pentagon states that cyber threat to national security is growing. Pentagon is looking into an option of using cyber security shield to safe guard its military information. This shield is called Blockchain Technology.
The Blockchain Technology is regarded as a secure firewall for networks, especially where a lot of financial transactions take place like internet gambling services. Blockchain Technology is a technological innovation of Bitcoin. Bitcoin uses this technology to protect its accounts from hacks. It records valuable information especially transaction between two parties into incorruptible blocks not only financial information but any essential information. Once the block is created it is stored into permanent data and another new block is created. Blockchain is designed to be secure and these blocks are resistant to any changes without altering all the blocks.
Therefore make information safe from any threat. Blockchain is useful in recording health information, events, financial transaction processing, and records management including documentation and identity management. It is designed to protect the company’s units and departments. It is also usable on aeroplanes, connected vehicles, and satellites.
