Cybersecurity Concepts Every Beginner Must Know
In the modern era, most businesses depend on reliable internet access for their daily operations. Students almost always use the internet to help them with their schoolwork, research papers, and homework. Most people cannot imagine going without the internet for even a single day. Therefore, everyone needs to make sure they protect their internet access with the right cybersecurity measures. When it comes to cybersecurity, there are a few important points that everyone has to keep in mind.
An Introduction to Cybersecurity
Today, technology plays a significant role in the success of companies all over the world. To maintain an edge on their competition, they need to ensure that they maximize their efficiency and productivity using the internet with cybersecurity jobs. Simultaneously, this technology has also made companies more vulnerable than they ever were in the past. Therefore, it is critical to employ advanced cybersecurity measures. With this in mind, you must understand what cybersecurity is, why this technology is essential, and how it can be used to protect employees, businesses, customers, and data. By paying a high salary for cybersecurity to someone with a cybersecurity degree or the right cybersecurity certifications, companies can protect themselves against some of the biggest threats.
What Is Cybersecurity?
First, it is important to cover what cybersecurity and information technology security are. This is a large, broad term that encompasses practices, processes, and technology designed to protect an organization, company, or business's devices, data, networks, and programs from attacks, unauthorized access, and other types of damage. While cybersecurity is used to protect people against malware and viruses, it is also used to protect businesses from natural disasters.
There are numerous types of cybersecurity involved. For example:
Network security is designed to protect a company’s networks and servers from harm.
On the other hand, application security is usually employed for computer and mobile web applications.
Informational security is also used to ensure that information is protected as it moves from place to place.
Finally, operational security often involves physical systems that are used to prevent cyber attacks from taking place.
Also, it is important to notice some of the most common reasons why cybersecurity is so critical. Government, corporate, military, financial, and even medical organizations process and store tremendous amounts of information daily. Much of this information is incredibly sensitive. Besides top-secret files that are likely on government and military devices, even healthcare organizations need to protect patient information under HIPAA laws. If consumer information is not protected, then this will undermine consumer confidence in organizations of all types. Therefore, it is important to ensure that all information is adequately protected using cybersecurity measures.
If correct measures are not employed, then there is a significant risk that hackers or cyber criminals could end up stealing information and using it for personal gain. For example, they could use this information to open up accounts in other people’s names or even steal bank account records directly. With this in mind, it is critical to employ the right cybersecurity professionals to ensure that this information is protected from harm. Because cyber threats come in many shapes and forms, everyone needs to stay up-to-date on the cybersecurity field’s latest developments. By working hard to remain ahead of hackers, it is possible to prevent these attacks from taking place, which is always preferable to cleaning up the results of these attacks after they have already happened.
Elements of Cybersecurity
During the past few years, there have been significant advancements in the world of cybersecurity, cyber crime, and cyberterror. As a result, these systems have become more complicated than they ever have been. With this in mind, a comprehensive cybersecurity system must ensure that information and equipment are protected from end-to-end. Therefore, some of the most important elements of cybersecurity include:
- Endpoint Security: Many organizations store their data remotely today; however, this can also be a vulnerable location. Remember that if employees and staff can access information remotely, then it could also be accessed by criminals. Endpoint security focuses on protecting remote access to sensitive files. Some of the most common endpoint security measures include VPNs, firewalls, and other tools.
- Data Security: Data security is a broad term that encompasses all forms of data protection. For example, this could be something as simple as a username and password that restricts access only to those who have the right credentials. This could also include encryption methods that protect data as it is transferred from place to place. Data security is one of the foundational pillars of cybersecurity as a whole.
- Identity Management: This critical part of cybersecurity ensures that everyone has access to the right information. Specifically, nobody should ever have access to something that they do not need to do their job. Reducing the number of people who have access to specific files minimizes the risk of company data being compromised if one set of credentials is stolen.
- Database and Infrastructure Security: This area of cybersecurity focuses on physical barriers that are in place. These barriers are used to prevent criminals from accessing hardware or stealing it. This could include something as simple as a lock or something as advanced as a comprehensive security system.
- Cloud Security: The cloud has become an integral part of internet use. Employees can upload information to the cloud, allowing others to access it without generating a long email chain. At the same time, the cloud also makes organizations more vulnerable. Cloud security focuses on protecting information that is stored on the cloud from harm.
- Mobile Security: Every day, more sensitive information is uploaded to phones. Therefore, all phones need to be protected appropriately. In addition to having a strong password, mobile security also focuses on making sure no information is stored on a phone unless it has to be and teaches others how to safely connect to a mobile network.
- Disaster Recovery and Business Continuity Planning: In addition to hackers, natural disasters are also a significant threat. This could take the form of a fire, a hurricane, or a tornado. If a natural disaster strikes a physical location, it is crucial to ensure the business can continue operating. This is where a business continuity plan comes into play. With the right disaster recovery services, the damage can be cleaned up quickly, and files can be restored.
- End-User Education: When it comes to cybersecurity, it is always more effective when everyone is pitching in. This is where end-user education is essential. In this manner, employees will be educated on the current best practices, ensuring they can keep themselves and their peers safe from harm.
- Data Loss Prevention: If companies lose their data, this could set them back years. Therefore, the data needs to be protected. This is where the 3, 2, 1 rule is important when it comes to data backup. Ideally, there should be three separate sets of data stored on two different media types, with one location being off-site. By protecting data from being lost, businesses can solidify their operations.
- Intrusion Detection System: Lastly, it is essential to cover an intrusion detection system. The system is put in place to alert key professionals if unauthorized access to the company's system is detected. For example, this might include a text message sent to the IT department or an email sent to a manager. The goal is to lock down the system after this intrusion has taken place and trace the signal to see where it came from.
This represents just a couple of the key elements that go into a comprehensive cybersecurity plan. It is important to ensure that every cybersecurity strategy includes these elements so that employees and their data can be protected from harm.
Cybersecurity Threats and Attacks
To prevent a cyber threat or a cyber attack from taking place, it is important to understand what they are. There are several key types of cybersecurity threats and attacks that everyone should know, often covered by the National Institute of Standards and Technology or NIST. They include:
There are several ways criminals might aim to gain access to a business network and compromise its sensitive data. If employees can understand these attacks and how they take place, it could prevent them from unfolding. Some of the most common types of threats in the world of cybersecurity include:
- Hacking: Without a doubt, this is the most common type of cybersecurity threat. The goal of hacking is to gain authorized access to the company's system. In some cases, hackers possess credentials that they have stolen. In other cases, hackers might seek to execute a brute force attack, where they simply try to go through combinations as quickly as possible until the network is unlocked.
- Trojans: A trojan horse attack is a traditional type of cybersecurity threat. With this type of attack, a hacker will seek to email a file to a company or an individual containing a virus but disguising it as legitimate. When the file is opened, the virus is released, and the attack unfolds.
- Phishing: A phishing attack is a prevalent type of cybersecurity threat. With this type of attack, a hacker seeks to disguise themselves as a company member, trying to convince someone to surrender login credentials. Then, with these credentials, the hacker can execute an attack on the company's system.
- Spear Phishing: This is a variation on the traditional fishing attack. A phishing attack usually targets many people at once; however, a spear phishing attack typically leverages social media accounts and other information to individually target a single person. Then, once that person surrenders their credentials, the hacker can gain access to the network.
- Malware: Malware is a generic term used to describe a wide variety of viruses and cybersecurity threats. Several significant issues could be caused by malware. For example, some types of malware simply act to slow down the network, making it impossible for the network to keep moving. In other situations, malware might seek to steal sensitive information before releasing it to the public. Malware detection is critical and strong security programs can help.
- Social Engineering: This is just another name that is used to describe spear phishing attacks. These attacks turn to social engineering because they leverage social interaction to get people to surrender their login information. The best way to prevent these attacks from taking place is to educate employees on how these attacks unfold, the threats they pose, and what they should do if they think someone has targeted them.
- Cross-Site Scripting: This is usually shortened to XSS. This is a common vulnerability in specific scripts that hackers can exploit. Found in web applications, client-side scripts are injected into popular webpages. Then, using these scripts, hackers can access sensitive information when people visit the website.
- Ransomware: One of the most terrifying types of cyber attacks out there, a ransomware attack, is used to lock up a company’s network or server completely. When a ransomware attack is executed, everything on the system is encrypted, rendering it unusable. Companies are then asked for a ransom by the hackers, who will not release the network until the ransom is paid. Even though companies can try to unlock the network themselves, time is costing them money. If this attack is executed on a healthcare system, it can even take down critical life support systems.
- DNS Spoofing: Often, this attack is also referred to as DNA cache poisoning. In this attack, a corrupt data code is introduced into the resolver of the DNS system. When this malicious code reaches a server, the server ends up returning incorrect information. As a result, hackers can gain access to sensitive data that is owned by the company.
These are a few of the biggest threats that companies need to keep in mind when it comes to the world of cybersecurity today. Also, there are other types of cybersecurity attacks that could be launched as well.
When developing a cybersecurity framework, it is vital to know the cybersecurity attacks that could take place. Some of the most common attacks that everyone should know include:
- Drive-By Attack: In a drive-by attack, a hacker looks for insecure websites that could be vulnerable. Then, when this website is identified, the hacker will upload malicious scripts onto the pages. As a result, once a person visits the site, this malware reaches their computer and provides the hacker with access.
- SQL Injection Attack: Using an SQL query that is taken from the database, commands are inserted into the data plane itself. Then, the hacker will be rewarded with admin privileges, which he or she can use to steal information, steal login credentials, and shut down the database itself.
- Secure Sockets Layer Attack: In a secure sockets layer attack, a hacker seeks to exploit a gap between the user’s commands and where the website receives the commands. As a result, the hacker can intercept data as it moves from place to place.
- Eavesdropping Attack: This is another attack that hackers can use to intercept data that is in transit. By eavesdropping on individuals who send data back and forth, hackers can read this information as it flows through cyber space.
- Password Attack: This is a term used to describe any attack used to steal someone's password. For example, this could include a phishing attack or a brute force attack that is often used to access a company’s network.
- Birthday Attack: In a birthday attack, hackers will replace a legitimate message with a fake one, using something called a hash function. As a result, this type of attack is used to abuse communication privileges reserved for two parties.
- Man in the Middle Attack: Typically, data is encrypted once it leaves the computer. It also gets encrypted when it arrives at its destination. Along the way, the data might not be encrypted. Therefore, someone in the middle could steal it, which takes place in this attack.
- Denial or Distributed Denial of Service Attack: One of the most devastating cybersecurity attacks out there, the goal of this attack is to completely overwhelm a network or a system of so many commands that it cannot possibly handle all of them. Therefore, it does not respond to any of these commands and the network ends up completely shutting down.
These are just a few of the most common types of cyber attacks that might take place. Therefore, everyone needs to be prepared for these attacks and understand how to deal with them appropriately.
Threats of Having Poor Cybersecurity in Place
Many organizations are looking for ways to save money. As a result, they may not invest in proper cybersecurity resources. Some of the biggest threats of having for cybersecurity include:
- Customers are going to lose faith in the company because they do not think the company is protecting their data.
- When a company does not invest in appropriate cybersecurity measures, they end up losing a lot of their resources when they get hacked, which costs a tremendous amount of time and money.
- In some cases, particularly when it comes to severe ransomware attacks, the company might be forced to close completely.
For these reasons, it is important to invest in strong cybersecurity measures.
Cybersecurity in the Workplace
It is essential to take a look at cybersecurity in the workplace. The only way cybersecurity is going to work is if everyone is involved.
Why is Cybersecurity Important to Employees?
There are several reasons why this is so important when it comes to cybersecurity training for employees. These include:
- Cyber attacks often target those who do not have a lot of education in the world of technology, which includes standard staff and employees.
- Often, cyber threats are first detected by employees, so they need to be trained to recognize them.
- When employees are properly trained, they are more likely to invest in appropriate cybersecurity measures, protecting the company's data as well as their data from harm.
When everyone is involved in cybersecurity, there is a greater chance of data being protected.
Cybersecurity Best Practices
Finally, it is essential to cover the best cybersecurity practices. To execute a comprehensive cybersecurity strategy, some of the key best practices include:
- All data has to be protected at all times. This includes guarding against viruses and malware that are also protecting against natural disasters.
- All employees need to be taught the basics of cybersecurity themselves. This includes avoiding pop-ups, not opening unknown emails, and not clicking on mysterious links.
- Practice data backup and hygiene by following the 3, 2, 1 rule.
- Encourage all employees to practice proper password hygiene by changing their passwords regularly.
- All Wi-Fi connections have to be secured all the time.
- Everyone has to be trained on the rule of accessing remote files from various locations, ensuring that their connection is encrypted.
- When possible, try to employ two-factor authentication to reduce the chances of gaining access to the network with one set of credentials.
- Follow ICA or integrity, confidentiality and availability, which is critical to risk management.
Following these best practices can go a long way toward protecting the company from harm. By employing continuous monitoring as a part of cybersecurity management, it is possible to detect advanced persistent threats using general data protection regulation and protect businesses from harm.
