1. Artificial Intelligence & Machine Learning: 

Artificial Intelligence: Artificial Intelligence is the simulation of human Intelligence into the machines that are programmed to think as humans do and imitate their actions. This term can also be used for any machine which exhibits characteristics related to the human mind, like learning and problem-solving. The ideal feature of AI is its ability to simplify and undertake actions that are most likely to achieve a particular goal. Artificial Intelligence allows machines to learn from experience, adapt to new inputs, and carry out tasks similar to those of man.

Machine Learning: Machine Learning is a branch of artificial Intelligence that focuses on building intelligent computer systems using statistical techniques to learn from the data, determine the patterns and make decisions. Machine Learning makes use of complex algorithms that continuously iterate on large datasets, analyzing the patterns in the data and making it easier for machines to respond to the different situations where they have not been specifically programmed.

People you may know' suggestions on Facebook is one of the best examples for the use of Artificial Intelligence and Machine Learning. Did you ever wonder how you get 'People you may know' suggestions on Facebook? Facebook constantly notices which friends you connect with, which profiles you visit quite often, your workplace, your interests, etc. Based on continuous learning, a Facebook users list is suggested with whom you can become friends. 

2. Internet of Things:

The Internet of Things is about connecting any device with the Internet or other connected devices. The IoT is a huge network of connected objects and people who gather and share data about how they are used and the environment around them. It includes a number of objects of various sizes and shapes, from smart microwaves to self-driving cars, to wearable fitness devices. 

 Devices and objects equipped with integrated sensors are connected to an Internet of Things platform, which integrates the data of individual devices and implements analyses to share the most valuable information with applications that are designed to meet unique needs. 

 Smart homes are the best examples of the use of the Internet of things. Anyone would love it if we could switch on or off the lights even after we leave our home or unlock your door for your relatives or friends when you are not available at home. All these are possible with the help of smart homes. They make our life convenient and simple. With the help of the Internet of things, companies are building new products to satisfy our needs and make us comfortable.

3. Blockchain:

Blockchain is a system for storing information in such a way that it is very difficult and impossible to hack, cheat or change the system. A blockchain is basically a digital ledger of transactions which is duplicated and distributed throughout the whole network of computer systems on the blockchain. Every block in the chain holds certain amounts of transactions, and whenever a new transaction occurs on the chain, a record of this transaction will be added to all the participant's ledgers. The decentralized database handled by a number of participants is referred to as Distributed Ledger Technology. Blockchain technology is used for developing a standard security protocol because this is the most robust alternative to end-to-end encryption. It is also used for securing private messaging by setting up a unified API framework to support messaging capabilities between the messengers.

How is blockchain helping cyber security?

Blockchain has in-built transparency immutable and DTL features that can help solve today's cybersecurity problems. These features of blockchain help to handle the integrity, confidentiality, and availability of the information. Moreover, Blockchain systems are decentralized. So, the failure of one node does not affect the whole network.

4.Cloud Computing:

Cloud Computing is the provision of a number of services over the Internet. This resource contains applications and tools such as databases, servers, data storage, software, and networking. Instead of retaining the files on a local storage device or proprietary hard disk, cloud-based storage allows them to be stored in a remote database till the electronic device has access to the Web; it can access information and software programs for executing it.

Companies are moving towards cloud technologies by initial screening and analysis, Planning and designing, implementing the migration, tuning the target environment, final testing, and go-live.

Many factors of cloud computing are encouraging People and companies to move towards the cloud. They are increased productivity, scalability, environmentally friendly, cost-saving, performance, speed, efficiency, better data recovery, and security.

Potential risks of moving to the cloud:

Although cloud technology is the future of many technologies, without any doubt, there are certain risks that should be understood before migrating. Some of the risks to be considered are 

  • Migration may take time
  • Possibility of loss of existing data
  • Data architecture may be modified
  • Reduced control of data control through the third party
  • Visibility issues
  • New information stored on the cloud may be lost
  • Technical assistance is outsourced.

5. Web security:

Essentially, the Internet is an excellent way to connect to the whole world. We use the Internet as a means of connecting with others for sharing information, files for entertainment, socializing, and so on that might be helpful to us. Mobile technology, however, has enabled a much wider spread of the Internet, increasing the number of Internet users all over the world. The Internet remains the most democratic mass media. With very little investment, everyone can get a Web page on the Internet.

The number of Internet users worldwide has increased by 222 million in the last 12 months or over 600,000 new users per day. Globally, the number of Internet users is growing by nearly 5% a year, but annual growth is significantly greater in many developing economies.

Evolution of new technologies:

Technology continues to progress every day, resulting in new industries being created that have a significant impact on each industry. Technologies which are presently developing or which should be available in five to ten years and that are normally reserved for technologies which create, or are supposed to produce important social or economic impacts.

New technologies play an important role in modernizing industries. Emerging technologies may lead to further progress in the business. New technologies are helping companies to become a digital world. It is essential for every business to stay abreast of new technologies as we try to offer customized software solutions that meet the exact needs of our customers. Emerging technologies comprise various technologies like information technology, education technology, biotechnology, nanotechnology, robotics, cognitive science, and artificial Intelligence. Clearly, in the next decade, emerging technologies will advance and proliferate from 5G to advancements in artificial intelligence, the Internet of things, edge computing, machine learning, and others. They will bring major changes to our economy and transform whole industries.

Vulnerabilities in the Web:

Weaknesses that can result in an Internet user at risk of becoming a victim of Internet crime, for example, lack of knowledge of system vulnerability and current threats, are called vulnerabilities. Web application vulnerabilities have existed for years, largely because they do not validate or sanitize forms entries, incorrectly configured web servers, and application design defects and may be used to compromise the security of the application. How a computer vulnerability is used is dependent upon the vulnerability's nature and the attacker's motives. These vulnerabilities may exist due to unexpected interactions between various system components, software programs, or basic defects in an individual program. Some of the most common website security vulnerabilities are SQL injections, security misconfiguration, cross Site Scripting, Broken authentication & Session Management. Cross-site Request Forgery, Insecure direct object references.

With the evolution of technology, vulnerabilities in the web increases. So, Protective measures and protocols are to be adopted for protecting the organization from threats and cybercriminals which use the web channels. This is called web security. Web security is essential for the continuity of business and the protection of data, users, and companies against risks.

6. Application Security:

Applications are software's that allow the user to carry out specific tasks on a mobile device or computer. People look to apps to make life easier for them, and they are most likely to use them if it serves a particular purpose. Our research has shown that 2 out of 3 people will use an app frequently as it makes their lives easier. Mobile applications provide the ultimate convenience. You can order dinner, take a ride, and do many things from your phone. Some research suggests that revenues from global applications are projected to rise steadily from year to year. Applications that are likely to increase among users include food delivery, health care, transportation, social media, and gaming applications.

Data leaking through the apps 

Unauthorized data transmission from an organization to a receiver or an external destination is referred to as data leakage. Data leakage is also called slow data theft. It is a huge issue for data security, and damage to any organization, whatever its size or industry, may be serious. Apps are the main sources through which data leaks occur. What happens when your data gets leaked? Data leakage is when sensitive data is exposed physically or accidentally over the Internet or in some other form, that includes lost hard drives or laptops. It means that a cybercriminal can obtain unauthorized access to sensitive information effortlessly. Depending on the concerned data, the consequences may include corruption or destruction of databases, leakage of confidential information, theft of the intellectual property, and regulatory requirements for notifying and potentially compensating affected individuals.

Sometimes we find bugs in the applications. Most bugs are due to errors and mistakes made either in the design of a program, in its source code, or in the components and are used by these programs. Bugs can result in subtle effects, crash the program, or freeze the computer.

So, Developing, adding, and testing security features in applications for preventing security vulnerabilities from threats like unauthorized access and modification is very important. This is called application security.

7. Intrusion Detection System (IDS) and Intrusion Prevention System

IDS refers to the Intrusion Detection System. An IDS is intended to detect and monitor intrusions, and it requires human assistance or automated systems for interpreting the results and deciding whether to act or not. 

IPS refers to the Intrusion Prevention System. An IPS may choose to accept or reject packages depending on the rules. It must be updated to recognize the most recent threats.

IDS analyses network traffic to find signatures that correspond to known cyber attacks. IPS also analyzes packets but may prevent the packet from being delivered depending on the type of attacks it senses, which stops the attack.

How can IDS & IPS avoid potential risks?

Any company with an Internet connection has the potential to be vulnerable to network intruders. The easiest way to stop them is for blocking the services you don't need, neither at the entry point of your network nor on your computer. 

An IPS will prevent attacks by depositing malicious packets, blocking offensive IP addresses, and alerting security staff to potential threats. Such a system typically uses an existing database for signature recognition and may be programmed to recognize traffic-based attacks and behavioral anomalies.

When a security policy breach, virus, or configuration error is detected, an IDS may remove an offensive user from the network and send an alert to security staff. In addition, an IDS detects only continuous attacks and not incoming aggressions. In order to prevent them, an intrusion prevention system is needed.

8. Data loss prevention (DLP) & Data encryption:

Data loss happens when precious or sensitive information on the computer is compromised as a result of theft, software corruption, viruses, malware, human error, or power failure. It can also be caused by mechanical failure, physical damage, or building equipment. It is frequent for the data to obtain "lost" data to get corrupted or deleted unintentionally. For example, dropping the laptop hard drive may easily result in data loss or corruption, like malicious software or computer virus.

In order to avoid data loss, data must be encrypted. Data encryption is the security method in which information is encrypted and is accessed or decrypted by the user who has the appropriate encryption key. This is a wise choice for the protection of organizational information. A number of technologies for encrypting data are available. Some of them are AES, RSA, and DES. However, there are various encryption methods, choosing the right one is important. 

9. Firewalls:

A network security device which monitors the incoming and outgoing network traffic and chooses if it can allow or block specific traffic according to the set of security rules defined. A firewall may include software, hardware, or both. Firewalls are very important as they have had an enormous influence on modern security techniques and continue to be widely used. Most devices utilize firewalls or associated tools to monitor traffic and mitigate threats.  

Overview about different technologies:

When categorizing through what they protect, both kinds are host-based and network-based. Network-based firewalls protect whole networks together and are often physical. Host-based firewalls protect the individual peripherals called hosts and are software.

When categorizing through the filtering method, they are as follows:

Packet-filtering

Stateful inspection firewall

Proxy firewall

Next-Generation Firewall
How do firewalls protect against threats?

Firewalls protect against external cyber attackers by keeping your computer or network safe from malicious or unwanted network traffic. It can also prevent malicious software from accessing a computer or network over the Internet.

Firewalls block any unauthorized connections to your computer and even allow you to choose what programs may access the Internet so that you are never logged in without knowing it.

10. Social engineering or insider threat:

Social engineering is a manipulative technique which uses human error for the purpose of obtaining access, personal information, or valuables. In cybercrime, "human hacking" scams tend to attract unsuspecting users to expose data, spread malicious software infections, or give restricted systems access.

A malicious attack by a person or organization that attempts to corrupt data, access a network, or steal sensitive information will be a threat. No company is immune from cyber-attacks and the resulting data breaches, and certain cyberattacks may even destroy computer systems. As cyber threats become more sophisticated, a company needs to put in place the security necessary to protect its data and networks.
