Blockchain as a driver for cybersecurity

With an increased sophistication of technology, the onslaught of cyber attacks is on a dramatic rise.
Today, almost every business is under threat from online attacks. Cyber attack ranges from data theft to disruption of the hardware infrastructure. The investment in cyber defense systems has also witnessed a surge, both for government and private entities. Blockchain technology is widely being adopted by these companies to boost their online security systems. With advanced cryptography, companies can stay safe from most cyber-attacks today.

Key reasons for the success of blockchain in boosting up cybersecurity are:

1. Blockchain is permanent and transparent

The information storage mechanism offered by blockchain is decentralised in nature. Traditional databases are centralized, in all IT and non-IT companies. Here, each and every line of coding is concentrated in a single place. Therefore, they are prone to cyber threats. Even if the companies make back-ups of the information regularly, they are not completely secure from threats. As blockchain is more extensive, synchronised across multiple systems, it is impossible for the hackers to tamper with the information. These blocks of information are linked to each other. As they are not concentrated in a particular place, hackers are unable to steal data. It is the key reason why more and more organizations are switching to blockchain-based security system.

2. Versatile use

The increasing incorporation of Blockchain in different industries is due to its versatility. As evident in Bitcoin cryptocurrency, blockchain can be used in monetary transactions. Therefore, a number of companies are using the technology to secure their online fund’s transfer mechanism. From electronic voting to verification of bank accounts, the technology is compatible with various types of use. In a nutshell, blockchain can protect the entire business infrastructure.
The versatility of blockchain is evident in the healthcare industry as well. Different healthcare organizations are trying to utilize this concept for easy transaction of patient-related data. Apart from this, other industries are using it to track the movement of money and assets through the supply chain of manufacturers. Retailers are also using this technology to deal with their suppliers electronically. The easy identification process offered by blockchain makes the entire system fool-proof.

3. Protection of data integrity

CISA dumps He stood there 300-320 Dumps PDF for a long ADM-201 Practice Exam time. Tami Joan and John desperately retreated until they reached the other side of the 300-320 Dumps PDF door, holding two sweaty bodies tightly together. The drivers hand bent into the shape of a cup, blocking the lights shone on the street light, looked Learnguidepdf at them more carefully. Suddenly, a loud 300-320 Dumps PDF noise echoed in the air. Tameron could not help but constricted a while, and John made a short, screaming scream. Behind the driver, the air in the distance was filled with bright red and blue flame stripes instantly. Then again is ADM-201 Practice Exam a few roar and scream. The driver Testprepwell turns 300-320 Dumps PDF and looks up, just to see a huge, orange-red cobweb over the city. It was a fireworks, and Tamie remembered the news read in the newspaper.

Therefore, there is no other way to pour back into the past to understand what the reporter said is a piece of open space. The headquarters radio said He said it was on the 37th Street near Eleventh Street. Those at the Notification Center never figured out where the ADM-201 Practice Exam exact location of CISA dumps the murder was. Although it is nine oclock in the morning, it has made people sweat more than 300-320 Dumps PDF hot. Emilia Shakes lay aside a tall grass thatch. She is conducting a search of light – a jargon of crime scene investigators – searching for suspicious objects with an S-shaped route. Nothing at all She looked down at the intercom on the dark 300-320 Dumps PDF blue uniform shirt. Patrolman 5885 calls headquarters without any notice. Do you have Learnguidepdf any further news Testprepwell The dispatcher replied in a bumpy noise 5885, there is no more information about the scene of the crime at the moment, but one thing The informant said he 300-320 Dumps PDF hoped the victim was dead. Please say it again, headquarters. The complainant said he hoped the victim was already dead. He said it would be best if so. Finished. Hopefully the victim Dead Shakes struggled across a Testprepwell broken barbed wire Learnguidepdf and began searching 300-320 Dumps PDF for another piece ADM-201 Practice Exam of open Learnguidepdf Testprepwell space. Still not found. She wants to leave. Just call CISA dumps 10-90, report that without any discovery, you can return to the CISA dumps Si Si area, it is her daily patrol area. Her knees hurt and Testprepwell CISA dumps she felt as if she had been roasted on CISA dumps a terrible August day. She just wanted to slip to the Port Authority and get stuck with the Little Furrier there and come back to a large can of Arizona iced tea. Then, at eleven thirty CISA dumps – just two hours now – she was able to clear the drawers in the south section of Midtown and go to the lower town for training. But she finally did not do this. She can not leave this briefing without answering the phone call. As she continued to move on, she walked along the hot sidewalk through Learnguidepdf CISA dumps the path between the two abandoned apartments and into another covered, planted Testprepwell area. She slid her slender forefinger down into her flat-top hat and scratched it with irresistible restraints through layers of long, red hair on her head. In order to scratch Testprepwell more scalp, ADM-201 Practice Exam she simply faded her cap side, while crazy scratch. Sweat streaming down her forehead, itchy, Learnguidepdf so she fiercely blew a few brows.

He hurriedly recorded his conversation ADM-201 Practice Exam in a black book with a sweaty pen. Oh, just do it. Now, go to those trash cans, stay there and direct the traffic until the entire Learnguidepdf street is clear. Did you hear that She turned ADM-201 Practice Exam and left without saying anything good or not, A ADM-201 Practice Exam street, began to slowly move a few ADM-201 Practice Exam trash cans. Every driver who passed by her glared at her, and some mumbled in her mouth. Shakes glanced at the watch. 300-320 Dumps PDF Another hour Learnguidepdf I can hold on. 3 The peregrine falcon gently waving a few wings, landing in the edge of the windowsill. CISA dumps Outside the window, noon the sun bright and dazzling, the weather seems Learnguidepdf to be extremely hot. Finally, the man murmured, turning ADM-201 Practice Exam his head to the buzzing doorbell ADM-201 Practice Exam and looking at the door to the downstairs. Is ADM-201 Practice Exam he He shouted at the staircase, is it Lincoln Lyme turned his head to the window CISA dumps again without hearing any answer. The peregrine falcons head turned a little and moved very fast, just like a spasm, immediately returning to the original elegant gesture of keeping. 300-320 Dumps PDF Lyme noticed the blood Testprepwell stained its paw, and a piece of yellowish flesh was pulled by its small, black, nut shell-like beak. It stretches short neck, move slowly to the nest, the action is reminiscent of not a bird, but a 300-320 Dumps PDF ADM-201 Practice Exam snake. The peregrine 300-320 Dumps PDF Falcon dropped the meat into the small mouth of a blue-winged bird. CISA dumps What I now see is the only Testprepwell Testprepwell creature in New York City without any natural enemies, CISA dumps Lyme thought. Maybe God except God. He heard footsteps, and someone was walking up the stairs. Is he He asked Thomas. The young man answered, No. Who is that The doorbell rang, CISA dumps is not it Thomass eyes looked at the window. Learnguidepdf The bird is back.Look, ADM-201 Practice Exam theres blood on your windowsill.Do you see them The female peregrine faltered slowly into Lymes gaze. A blue-gray feather, gorgeous Testprepwell like fish. It is looking up, looking back and forth toward the sky. They are always together, Testprepwell will they be with them for life Exclaimed Thomas. Testprepwell Like a geese Lymes eyes returned to Thomas. The latter was bowing his strong, young waist Learnguidepdf forward, looking through the window, which was splashed with rain. Testprepwell Who is here Lyme asked again. He was annoyed by the deliberate delay of young people. Visitors. Visitors Ha 300-320 Dumps PDF Lyme snorted. He tried to 300-320 Dumps PDF recall when the last guest visit was. That is at least three months ago. Who was the guest last visited Maybe those reporters, or a distant relatives. Thats CISA dumps right, its Peter Chter, a spine neurologist in Lyme. Blaine has been here several times, but she certainly can not be a Learnguidepdf visitor. Its so cold here, complains Tommy, reaching out to Learnguidepdf open the window at the same time. Young typical performance. Lyme thought. Do not open the window, he ordered, ADM-201 Practice Exam well, tell me whos coming Its 300-320 Dumps PDF cold. Youre going to scare the bird.You can turn off the air conditioner.Ill be closed. Lets open again, said Tangmajas forcefully to lift the thick wooden frame of the window. The two birds got accustomed to playing CISA dumps since they moved in. Learnguidepdf Hearing the noise, the two peregrine falcons turned their heads and widened their eyes to the source of the noise. But they were just wide-eyed, still on the edge of the bay Learnguidepdf windows, overlooking monarchs overlooking the collapsed ginkgo trees in their territory and the Learnguidepdf car parked on both sides of the street. Lyme asked again Whos coming Leon Salet. Leon What did he do Thomas looked back and forth at the room.

Blockchains can maintain the integrity of data better than the ordinary systems. In normal conditions, files and documents are signed with private keys. The source of data is verified by the users. It is difficult to prove that no tampering has been made with the private keys. Altogether, the process is too complicated. In Blockchain technology, no secrets are to be maintained. It is a transparent process which makes it easy to be adopted by the professionals. A startup company, called GuardTime, is developing a project that will replace data authentication based on keys. It is known as KSI or Keyless Signature Structure. It stores original data hashes and files in the system and eases up the process. In brief, it can detect any change made to the original data. With these technologies coming up, it is obvious that blockchain is the future of cybersecurity.
The concept of blockchain rests on the integrity of the system.

People have not yet focussed on its availability and confidentiality. These are more important areas to think about. The concept is still new and a lot has to be explored to reap the benefit of the technology. If it can be incorporated wisely, it will revolutionize cybersecurity in the near future. It has a lot of potentials to be incorporated within a peer to peer transactions in different industries.
