The technique of protecting internet-connected systems like computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks is known as cybersecurity. We are able to divide cybersecurity into two parts cyber, and the other is security. Cyber refers to the technology that includes systems, networks, programs, and data. And security is concerned with the protection of systems, networks, applications, and information. In some cases, it's also called electronic information security or information technology security. Cyber Security Classes Online is a basic tutorial where we can quickly understand the topics discussed if we have a basic understanding of how a firm or organization handles computer security. It's also helpful for us to have some prior experience with computer updates, firewalls, antiviruses, and other security measures.
"Cyber Security is the body of technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, theft, damage, modification or unauthorized access."
"Cyber Security is the set of principles and practices designed to protect our computing resources and online information against threats."
Cybersecurity is the protection of Internet-connected systems, including hardware, software, and data from cyber attackers. It's primarily about people, processes, and technologies working together to encompass the full range of threat reduction, vulnerability reduction, deterrence, international engagement, and recovery policies and activities, including computer network operations, information assurance, law enforcement, etc.
Cyber-attack is now an international concern. It's given many concerns that could endanger the global economy. As the volume of cyber-attacks grows, companies and organizations, especially people who deal with information related to national security, health, or financial records, need to take steps to protect their sensitive business and personal information.
This Cyber Security tutorial provides basic and advanced concepts of Cyber Security technology. It'll cover the most popular concept of Cyber Security, like what is Cyber Security, Cyber Security goals, types of cyber-attacks, types of cyber attackers, policies, digital signatures, Cyber Security tools, security risk analysis, challenges, etc.
With an immense number of companies and entities climbing onto the digital bandwagon, cybersecurity considerations have come up as limelight. Besides, new technologies such as Big Data, IoT, and Artificial Intelligence/Machine Learning are gradually more making inroads into our everyday lives, the threats related to cybercrime are mounting as well. Additionally, the usage of mobile and web apps in transacting financial information has put the complete digital stuff exposed to cybersecurity breaches. The inherent risks and vulnerabilities found in such apps can be exploited by attackers or cybercriminals to draw off crucial information data counting money. Internationally, cyber-security breaches have caused a yearly loss of USD 20.38 million in 2019 (Source: Statista). Plus, cybercrime has led to a 0.80 percent loss of the entire world’s Gross domestic product, which sums up to approx. USD 2.1 trillion in the year 2019 alone (Source: Cybriant.com).

Cybersecurity will, without a doubt, be one of the foremost influential areas of technology in 2019. But if you’re within the world of recruitment, it might be both your meal ticket and your ruin, simultaneously growing and killing your business.
Over the last 12 months, the planet has seen a number of the most important data breaches and cyber attacks in history, including Facebook. Recruitment agencies have long been a target for attacks. Why? Because recruiters hold the one thing that hackers love: data, and much of it.
But there’s a silver lining: there’s the business to be made within the cybersecurity.
The average salary for a cybersecurity professional rose by 7% from 2017 to 2018. the world is lucrative for both candidates and recruiters, but there’s a catch; there simply aren’t enough people to fill these roles. If this skills gap persists, who will come to your rescue once you become the victim of a cyber attack?
Getting your head out of the sand
Recruiters got to be bold and stop ignoring the glaringly obvious potential that cybersecurity brings to the staffing sector. Grab the prospect to grow your business through cybersecurity before you lose the chance because the market is there for those that are able to take it. Identifying, targeting, and placing the simplest cybersecurity talent are going to be the most important growth enabler for your recruitment business in 2017, but getting there requires addressing a number of the subsequent points:
Cybersecurity: the double-edged sword
The proverb ‘ life by the sword, die by the sword’ couldn’t be more apt when it involves recruitment and cybersecurity. Yes, there’s huge potential for business growth and development in cybercrime, but if you’re not careful you’ll find yourself being your candidate’s future client.If you are intrested to became expert in Cyber Security then join online cyber security course class and improve your skills.
If you think that your recruitment consultancy is immune from cyber attacks, you’re wrong. Recruitment agencies are keepers of a number of the world’s largest collections of knowledge – perfect fodder for gluttonous cybercriminals. Suffering a knowledge breach or hack isn’t only a logistical nightmare, but a significant dent in their credibility. Neither candidates nor clients want to figure with a recruiter that’s an information security risk and therefore the damage from such an attack might be costly.
For those businesses who haven’t yet acknowledged the severity of cybercrime, it’s time to awaken and prepare yourself for what might be a business-critical event and implement security measures that will keep your data safe.
Throughout 2019 and into 2020, cybersecurity will still be an enormous pressure that will come down hit businesses of all sizes sort of a tonne of bricks. So, grab the chance that this UK-wide skills gap presents and be a part of the subsequent wave of talented cybersecurity professionals just in case you would like their assistance at some point.

Everything around us has become smart, like smart infrastructures, smart cities, autonomous vehicles, to name a few. The innovation of smart devices makes it possible to achieve these heights in science and technology. But, data is vulnerable, there is a risk of attack by cybercriminals. To get started, let’s know about IoT devices.
The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.
Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.
When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.
When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.
Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.
The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.
Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.
If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.
When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.
Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.
Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.
Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.
There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.
Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.
Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.
Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.
When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.
However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.
If you have any, feel free to share them in the comments! I’d love to know them.

Cyber security is a human issue before it is technological. This is why all companies — whatever their size — must work on bringing awareness of these issues to their employees. Today, companies are targeted, because hackers ultimately are looking to access their customers and suppliers. Cyber security is therefore no longer a niche activity and, above all, is no longer something that can be ignored or put aside.
Today’s hackers have changed since the early days of the Internet. Cyber attacks have become sneakier, and hackers no longer try to take on company security systems head on. Instead, one option for them is Social Hacking.
Social Hacking is a technique used by business employees via mailing (for example) to penetrate the business network. This is why a quarter of the attacks recorded target employees.
Another technique often used is a rebound attack. This makes it possible to reach companies with sensitive information, such as those in the medical or defense fields. Hackers go through one of the company’s suppliers or customers to attack by rebound, taking advantage of the links maintained between these companies.
Another important point: hackers don’t just steal data. For example, the vast majority of international trade is done by boat. Hackers can hijack entire ships. And they already have! How? After cutting off communications to the vessel, they directed it to a safe place, and the cargo was not seen again until the ransom was paid. This type of cyber-attack could cost the target business hundreds of million dollars!
Agricultural equipment (tractors, harvesters, riding mowers, etc.), which is now connected to the internet, is another target of choice. It becomes possible to deviate from their initial trajectory. Hijacked, coordinated, and controlled, this material becomes a potentially dangerous weapon.
In the same vein, by simply buying a virus from the darknet for a few hundred dollars, a single individual can block a factory, a road, or even an entire city.
Depending on the type of business attacked and the type of information stolen, the solution is not the same across the board. Some industries are forced to give in to blackmail by cyber criminals, while others categorically refuse.
Take, for example, the Rouen hospital. In November 2019, the Rouen University Hospital was the target of a cyber attack. The extreme sensitivity of the stolen information and the lack of backup forced the entity to pay to recover the data. The aim here was to save lives in intensive care, to plan the right operations at the right time for the right patient, to communicate the right health data to the doctors who will prescribe treatment, among others. Quickly retrieving patient data was therefore essential.
In contrast, we can look at the seaside resort of La Croix-Valmer. The municipality’s computer servers were attacked at the end of July 2018. The files were encrypted and the hackers demanded a ransom. According to the municipality, no amount of money has been paid.
Indeed, despite the immobilization of services for a week, the municipality has managed to keep the personal data of the inhabitants safe from attack. This time, the hackers did not gain anything.
1. Develop adequate technical means
The first key step to secure a network is to acquire a firewall that allows partition networks. A typical business generally has several of them: the document network, the accounting network, etc.
This compartmentalization technique makes it possible to cope with an attack, preventing it from spreading to other networks than the one through which the hackers entered. The IT systems manager adds anti-virus, anti-spam, and other services and solutions to optimize network protection.
2. Never ignore awareness
When securing your network, it is also essential to educate your users about cyber security through events, conferences, webinars, etc. An informed user—aware for example that 40% of attacks take less than 30 seconds for the virus to take possession of the entire network—fwill think of disconnecting his computer quickly if he finds that it is under attack.
3. Achieve the security targets required to obtain certifications
Some industries need to prove their level of cybersecurity. This can be established by pursuing certifications. The term “security target” also designates the minimum security required by the industry to achieve a certain protection result. By reaching these security targets, the business can host sensitive data.
