Latest Technologies for Cyber Defence.

We have been hearing about cybersecurity vulnerabilities at every other organization in every newspaper we've opened in recent days. Even well-known technology companies ensure that their cybersecurity defences are up to date in order to prevent the leakage of any type of information, whether classified or non-classified. Cyber defence is a mechanism for defending a computer network that includes a quick response to breaches and the construction of a wall in the firm's infrastructure that acts as a security layer and guards the firm's sensitive information.

Cybercrime is no longer considered a minor offence. They've grown in lockstep with technological advancements. Gone are the days when cybercrime was used to steal a tiny sum of money from someone's bank account. Top-tier government organizations, such as the Pentagon, which is regarded the safest network, are now using cybersecurity. The fundamental reason for the progress in cyber defence is that fraudsters have advanced. Cybercriminals have access to technology that is far more advanced than any government has ever envisioned. Furthermore, as knowledge of the dark web has grown on the internet, cybercriminals have been able to disappear underground even before anyone detects them.

A the shared network connects all of the company activities. In reality, all commercial activities are now conducted online, in a digital format, with everything reliant on the system and its networks. This makes it easier for hackers to gain access to sensitive information. When data is breached, it casts a doubt on the company's integrity, and the firm's entire goodwill suffers as a result. When Facebook's data breach was revealed in 2018, it wreaked havoc on social media, prompting the #quitfacebook trend, which pushed the company to make significant revisions to its privacy policies. It even had an impact on the number of users Facebook had previously and now has. The legitimacy of all social media networks has been questioned as a result of one data breach.[1]

Governments and internet websites are not the sole targets of cyber-attacks; a city's electrical grid can also be hacked. This causes widespread public inconvenience. It has an impact on the revenues generated by local governments. Because the system is so badly damaged, the costs of repairing the entire electrical grid should be a major expense for the state government. Such cyber-attacks have an influence that extends beyond an individual to the country's economy and even political processes.

Artificial Intelligence (AI):

AI is currently the most talked-about term in the country. Artificial intelligence (AI) has a lot of potential in the field of cyber defence. Google is the best example of this type of technology. There is two-factor authentication whenever we try to log in to our Google account on a new device. This authentication confirms the user's identification on the basis of two or three separate grounds. These grounds could be something they already know, are, or possess.[2]

Deep learning is an advanced AI concept. The data is verified using deep learning. It keeps track of all transactions, including real-time communications, in order to detect any viruses or other malicious activity on your network.

Behavioural analytics:

Following the Facebook-Cambridge Scandal, one is fully aware of the exploitation of data for behavioural analysis. This strategy is commonly used to target the proper demographic on social media platforms and in online marketing. This form of technology, on the other hand, is still being researched and developed for sophisticated cyber defence systems. This method aids in determining a system's pattern and tracking network activity in order to detect a real-time threat or the likelihood of a threat in real time. A user's device, for example, may show an unusual rise in data transmission, which could signal a cybersecurity breach. While this type of technology is most commonly associated with networks, it can also be found in apps and devices is now also developing.

External Hardware Application:

A password or a numbered pin is insufficient to safeguard our devices against corruption. Embedded authenticators are proving to be one of the safest methods of confirming a user's identification. Intel, the world's leading chip manufacturer, has released the 6th Generation vPro Chips. These chips are extremely powerful user authentication chips that are built right into the hardware, eliminating the need for external storage. These chips, according to the business, will transform the structure of ‘Authentication Security,' since they are designed to work at various levels and authentication techniques in unison.

Blockchain Cybersecurity:

One of the most recent cybersecurity solutions is rapidly gaining traction and receiving the attention it deserves. The two parties to the transaction are identified using blockchain technology. This type of cybersecurity is based on the basics of peer-to-peer networks. The basic goal of blockchain is to establish trust in a distrustful environment. Every blockchain participant is completely responsible for verifying the veracity of the data they submit. Blockchains erect an impenetrable wall around the network that cannot be penetrated, ensuring that there are no chances of compromise.[3] To keep possible cyber risks at bay, blockchains normally establish a rigorous verification system. Consider the case of Mobilecoin.

Zero - Trust Model:

The name says it all: under this paradigm of cyber defence, it's considered that the network has already been compromised. As a result, the network can no longer be trusted, forcing a person to improve the network's internal and exterior security. The most important aspect of this type of cybersecurity approach is that it requires someone to improve both internal and external networks.[4] Even before the network is breached, it is presumed that it has already been breached, implying that the necessary protection will be provided. This includes identifying a company's key data, tracking the flow of that data, separating the logical and physical components, and ensuring that the company's policies are constantly reviewed and modified as needed.

India has almost 560 million internet users, making it the world's second-largest internet user. According to reports, because to the epidemic, this figure is likely to surpass 600 million users by the end of the year. On the other hand, these enormous figures necessitate the development of robust cyber defence technology. Though cybersecurity is improving every day, hackers are always improving their skills and seeking for new ways to get access to new systems. To ensure that cybercrime is reduced and that fraudsters' efforts are not in vain, certain regulations must be in place, and lawmakers must anticipate cybersecurity flaws and enact laws appropriately.
