Understanding Cybersecurity:

Cybersecurity is the protection of internet-connected systems, including hardware, software and data, from cyberattacks.

The goal of cybersecurity is to limit risk and protect IT assets from attackers with malicious intent.

Information security, which is designed to maintain the confidentiality, integrity and availability of data, is a subset of cybersecurity.

Cybersecurity measures should always be implemented to protect the data of small and large organizations and individuals.

Even though significant security breaches are the ones that often get publicized, small organizations still have to concern themselves with their security posture, as they may often be the target of viruses and phishing.

Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks.

These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.

What are the Cybersecurity best practices?

Cybersecurity best practices can, and should, be implemented by large and small organizations, employees and individuals.

One of the most problematic elements of cybersecurity is the continually evolving nature of security risks and advanced persistent threats (APTs).

The traditional approach has been to focus resources on crucial system components and protect against the biggest known threats, which meant leaving components undefended and not protecting systems against less dangerous risks.

To deal with the current environment, advisory organizations are promoting a more proactive and adaptive approach.


Types of Cyber Attacks:

Denial of Service Attack (DoS)

Hacking: What is Hacking?

During the 1990s, the term “hacker” originally denoted a skilled programmer proficient in machine code and computer operating systems.

In particular, these individuals could always hack on an unsatisfactory system to solve problems and engage in a little software company espionage by interpreting a competitor’s code.

Unfortunately, some of these hackers also became experts at accessing password-protected computers, files, and networks and came to known as “crackers.”

Of course, an effective and dangerous “cracker” must be a good hacker and the terms became intertwined.

Hacker won out in popular use and in the media and today refers to anyone who performs some form of computer sabotage

Malware.: what is the malware?

Malware (a portmanteau for malicious software) is any software intentionally designed to cause damage to a computer, server, client, or computer network (by contrast, software that causes unintentional harm due to some deficiency is typically described as a software bug).

A wide variety of types of malware exist, including computer viruses, worms, Trojan horses, ransomware, spyware, adware, and scareware.

Programs are also considered malware if they secretly act against the interests of the computer user.

For example, at one point Sony music Compact discs silently installed a rootkit on purchasers’ computers with the intention of preventing illicit copying, but which also reported on users’ listening habits, and unintentionally created extra security vulnerabilities.

A range of antivirus software, firewalls and other strategies are used to help protect against the introduction of malware, to help detect it if it is already present, and to recover from malware-associated malicious activity and attacks.


Phishing. What is phishing?

Phishing is a cyber attack that uses disguised email as a weapon.

The goal is to trick the email recipient into believing that the message is something they want or need — a request from their bank, for instance, or a note from someone in their company — and to click a link or download an attachment.

What really distinguishes phishing is the form the message takes:

the attackers masquerade as a trusted entity of some kind, often a real or plausibly real person, or a company the victim might do business with.

It’s one of the oldest types of cyberattacks, dating back to the 1990s, and it’s still one of the most widespread and pernicious, with phishing messages and techniques becoming increasingly sophisticated.

Spoofing. What is Spoofing?

In the context of information security, and especially network security, a spoofing attack is a situation in which a person or program successfully identifies as another by falsifying data, to gain an illegitimate advantage.

Spoofing is the act of disguising a communication from an unknown source as being from a known, trusted source.

Spoofing can apply to emails, phone calls, and websites, or can be more technical, such as a computer spoofing an IP address, Address Resolution Protocol (ARP), or Domain Name System (DNS) server.


Ransomware. What is ransomware?

Ransom malware, or ransomware, is a type of malware that prevents users from accessing their system or personal files and demands a ransom payment in order to regain access.

The earliest variants of ransomware were developed in the late 1980s, and payment was to be sent via snail mail.

Today, ransomware authors order that payment be sent via cryptocurrency or credit card.


Spamming.what is the Spamming?

An email inbox containing a large number of spam messages

Spamming is the use of messaging systems to send an unsolicited message (spam), especially advertising, as well as sending messages repeatedly on the same website.

While the most widely recognized form of spam is email spam, the term is applied to similar abuses in other media:

instant messaging spam, Usenet newsgroup spam, Web search engine spam, spam in blogs, wiki spam, online classified ads spam, mobile phone messaging spam, Internet forum spam, junk fax transmissions, social spam, spam mobile apps, television advertising and file sharing spam.

It is named after Spam, luncheon meat, by way of a Monty Python sketch about a restaurant that has Spam in every dish and where patrons annoyingly chant “Spam” over and over again.


What is cybersecurity all about?

A successful cybersecurity approach has multiple layers of protection spread across the computers, networks, programs, or data that one intends to keep safe.

In an organization, the people, processes, and technology must all complement one another to create an effective defence from cyber attacks.

A unified threat management system can automate integrations across select Cisco Security products and accelerate key security operations functions: detection, investigation, and remediation.


Why is cybersecurity important?

In today’s connected world, everyone benefits from advanced cyber defence programs.

At an individual level, a cybersecurity attack can result in everything from identity theft, to extortion attempts, to the loss of important data like family photos.

Everyone relies on critical infrastructures like power plants, hospitals, and financial service companies.

Securing these and other organizations is essential to keeping our society functioning.

Everyone also benefits from the work of cyber threat researchers, like the team of 250 threat researchers at Talos, who investigate new and emerging threats and cyber attack strategies. They reveal new vulnerabilities, educate the public on the importance of cybersecurity, and strengthen open source tools.

Their work makes the Internet safer for everyone.



Cybercrimes have become the latest battles to look forward to by the enterprises.

Whether it is a company, a healthcare system, a university, a government office or a military system, cyber crimes can creep in any of them to grab data and information.

This data is then used with malicious intention to either hack the site or rob money out of them. This makes any ecosystem on the web, quite vulnerable to the bot attacks.

In fact, the cost of a malware attack on a company is on average estimated at $2.4 million. Due to this risk, more and more company owners are investing in technology that prevents the war on the web.

“Global Risks Report 2019 suggests 80% disruption of operation and infrastructure due to cyber attacks.

82% risk is posed by the theft of data and money owing to cyber attacks.

How does Blockchain help to cybersecurity?

2018 was a rocky year security-wise.

Governments, universities, power companies and ‘big name’ enterprises became victims of elaborate hacks.

This year, 75% of CEOs and board members name cybersecurity and technology acquisitions among their top priorities.

Recently, NASA decided to implement blockchain technology in order to boost cybersecurity, and prevent denial of service and other attacks on air traffic services.

They will do this by using the same distributed ledger technology that is often associated with bitcoin and other cryptocurrencies.

How Does Blockchain Technology Impact Cyber Security?

Blockchain technology has trickled into every domain of our lives from banking to healthcare and beyond.

Cybersecurity is an industry which has been remarkably affected by this technology with scope for more in the future.

In short, blockchain can be used to protect our data from cyber-attacks and improve cybersecurity across industries.

Blockchain, a Distributed Ledger Technology (DLT), is focused on creating trust in an untrusting ecosystem, making it a potentially strong cybersecurity technology.

All members (or nodes) can record, pass along and view any transactional data that is encrypted onto their blockchain.

Blockchain is a distributed network that might have millions of users all around the world.

Each user can add information to the Blockchain and all data in the blockchain is secured by cryptography.

Another member of the network is responsible for verifying that the data inserted in the blockchain is real or not.

It is done by using a system of three keys i.e., public, private, and receiver’s key that enables members to check the accuracy of the data and also confirms from where does it come.

Moreover, blockchain users are also able to store all the data in their network on their computer system.

It results in two things. Firstly, they can earn more money for giving their extra storage space and, secondly, they assure that the chain will not collapse.

Like for instance, if a hacker attempts to tamper with a block, the entire system will analyze every single block of data to find that one block which differs from the rest.

If the system detects such a block, it only excludes it from the chain and identifies it as false.

Blockchain technology is designed in a way that there is no primary storage location.

Every user present on the network plays an essential role in storing some or all of the blockchain.

Everyone is solely responsible for verifying the data that is stored or shared to assure that the fake data can’t be added and any of the existing data cannot be removed.


One such way is to boost cybersecurity!

 Ways through Which Blockchain Technology Boosts Cybersecurity

DDoS Protection

A DDoS attack is an attack in which several compromised computer systems attack a target, like a server, website, or some network resources, and cause a denial of service for users of the targeted support.

The attack is rated as the most troublesome security threats that can easily compromise businesses.

Attackers can use several ways to initiate an attack, particularly sending tons of junk requests to a site, increasing traffic to the website that can no longer keep up with the applications.

The offence continues until the site gets subjugated with unwanted requests.

DDoS attacks have been taking place at an increasingly rapid rate and are affecting more prominent companies such as SoundCloud, Spotify, and Twitter.

Blockchain Saves Cybersecurity

By implementing blockchain technology, the Domain Name System (DNS) becomes fully decentralized and disturbs the contents to a large number of nodes and make it impossible for hackers to attack.

However, Domain editing rights are granted to only those who own them and no other person can make changes.

This reduces the risks of data being accessed or changed by unauthorized parties.

By using this advanced technology, a system can also make sure that it becomes invulnerable to hackers unless every single node is wiped out simultaneously.


Fraud & Identity Theft Protection

Identity theft is becoming a severe problem in the present age.

The cyber-criminals are using this identity to commit crimes, but with the incorporation of blockchain technology, this practice can be prevented.

Within the decentralized environment, the activities and the transactions will get accessed from your device by using the Decentralized Identity App.

By doing so, every completed transaction will keep on record and everyone will have access to either approve or disapprove it. If there is disapproval, the transaction will not be legal and acceptable.


Proving the Validity of Software Updates and Downloads

Trojan horses, worms, and viruses that invade computers appear in different forms. These are becoming challenging to identify with an untrained eye.

In recent times, ransomware and malware are also masquerading as legal apps. Blockchain steps in to allocate exclusive hashes for updates and downloads.

It makes a lot easier for users to compare the mixture of an intended download with that of the developer.

This significantly reduces the chances of infecting your system with viruses that are well masked.


IoT Security

IoT is making new opportunities and is providing a competitive benefit for businesses in new and existing markets. It traces everything- not just the data, but also how, when, where, and why you collect it.

The technologies that have resulted in the Internet of Things are not changing the internet but instead changing the things connected to the internet.

This includes the devices and gateways on the edge of the network that are now able to request a service without human interference at certain levels.

But the question has emerged at once on the dangers and possible risks of implanting the IoT in all aspects.

With hackers becoming better at hacking, they’re often gaining access to systems by exploiting the weakness in edge devices.

With the help of blockchain technology, it can be used to secure systems and methods from attacks.

Blockchain technology can protect the data exchanges which happen among the IoT devices. Moreover, it can also be used to gain real-time secure data transmissions and ensure timely communication between devices located miles apart.

Incorporating Security in Private Messaging Apps

Since conversational commerce is becoming more popular day by day, a lot of metadata is being obtained from customers during exchanges on social media.

While several messaging systems are using end-to-end encryption, others are starting to use blockchain to keep that information secure and protected.

At present, most of the messaging apps lack a standard set of security protocols along with a unified API framework for allowing cross-messenger communications.

The emerging secure blockchain communication ecosystems face this issue and work towards the creation of a unified interface.

Blockchain technology is an excellent solution for this as it protects all data exchanges and enables the connectivity between different messaging platforms, and newer networks like Bitcoin Cash promise to transmit far more information per block, moving us closer to a system of decentralized communication.


Blockchain Saves Cybersecurity

Final Thoughts

From all the above discussion, it is clear that no industry is safe from the clutches of hackers. As there is no foolproof method to curb hackers, blockchain technology has come to the rescue and has gone a long way to prevent data from getting into the wrong hands.

Hopefully, by carefully understanding the points mentioned above, you’ll also be successful in boosting cybersecurity with the help of blockchain technology.
