Why Is Cybersecurity Important?

A good cybersecurity system protects against a full range of cybersecurity threats, such as malware, spam, phishing, ransomware, DDoS (distributed denial of service) attacks, and corporate takeover (CATO). Using cybersecurity solutions benefits a company, its employees, and its customers because their confidential data can stay safe from unauthorized access.

Cybersecurity is also critical because it mitigates and responds to threats and detects them. As a result, when attackers try to access confidential information, the firewalls stop them from entering the database. However, if a hacker can enter and steal data, the cybersecurity system uses advanced technologies to recover it.

Who Is Cybersecurity Important for?

Using cybersecurity solutions is a must-have for:

  • Individual Internet Users: To gain protection for their data
  • Government Departments and Agencies: To safeguard the state’s secrets
  • Profit and Non-Profit Companies: To secure their client’s and employees’ private information
  • Educational Institutes: To prevent financial loss and student privacy breaches

Tailgating is a physical security breach that allows an unauthorized person to gain entry into a secure network. The unauthorized person forces their way in after an authorized user access the server. That is why it is also known as piggybacking. It is one of the most commonly used security breach techniques because the security system does not detect unapproved entries.

  • Threat Assessment

Threat assessment is a process of formally evaluating and verifying perceived threats that can harm a network system of an enterprise. It also describes the nature of the threat to ensure it is contained within time. The process starts by initially assessing the threat and learning which system vulnerability it targets. Then a follow-up assessment is carried out to create a mitigation plan.

  • Threat Hunting

Threat hunting, also referred to as cyber threat hunting, is a proactive cybersecurity search of networks, databases, data sets, and endpoints. It is carried out to discover and hunt unidentified malicious and suspicious activities that are difficult to detect with other security tools. It is a passive threat-detecting approach for monitoring data and systems for potential and existing security risks.

  • Threat Intelligence

Threat intelligence is a process of analyzing collected and processed data to detect cyber threats. It also facilitates understanding the threat’s motive and main target by checking attack behaviors. During the threat intelligence process, cybersecurity professionals sift through data and examine it to spot issues. Then they deploy specific problem-solving solutions to contain and eliminate the threat.

  • Traffic

 Traffic or network traffic is the total amount of data that transfers in and out of a network during a specific timeframe. The traffic is constantly monitored to identify malicious activities, security issues, operational problems, and anomalies. This practice allows you to learn about your network performance and minimize security attacks to strengthen network security.

  • Trojan Horse

Trojan horse or Trojan is a type of malware that disguises its malicious nature by presenting itself as a legitimate code or software. When the Trojan horse gains access to a network, it creates a way for attackers to carry out any action in the network. As a result, attackers can export files, modify data, delete important files, and alter the stored information according to their liking.

  • Two-factor Authentication (2FA)/Two-Step Authentication

Two-factor authentication (2FA) or two-step authentication is an identity and access management program that provides an additional layer of security. To access a 2FA system, users must provide two identification forms to acquire access to the data source. This increases server safety and allows businesses to monitor who is entering their databases and using their information.

  • User Authentication

User authentication is a security process that verifies the user’s identity before providing them access to a network or computing resource. Whenever a person tries to access a system, they must insert the correct credentials to obtain entry permission.

  • USB

A universal serial bus (USB) is a flash drive for storing, sharing, and transferring files from one device to another. If a USB is connected to an infected device, the virus or malware enters and corrupts the flash drive. When you insert a virus-infected USB into your computer system, the virus spreads and makes the files and data stored in your device unreadable.

  • VPN

A virtual private network (VPN) is a service that uses cryptography to create a safe encrypted online connection. People use VPNs while using the internet to hide their IP addresses to increase their privacy. VPN blocks geographical location, censoring the real identity and replacing it with an anonymous user.

  • Vulnerability

Vulnerability is a weakness in an organization’s IT system and infrastructure that can potentially be exploited by an attacker. A vulnerability can form due to a system flaw or feature error. Most attackers target more than one weak point to ensure the success of an attack. A successful attack provides attackers with unauthorized access to a network system.

  • WAF (Web Application Firewall)

A WAF or web application firewall is a protective software for web applications. It filters and monitors an app’s HTTP traffic from the internet. When WAF is deployed, it forms a protective barrier between the internet, the app, and the end user. This filters legitimate traffic from malicious ones, stopping the threat from infiltrating the central server.

  • Whaling

Whaling is a highly targeted spear phishing attack created for a company’s senior executives. It is a digitally enabled fraud that is disguised as a legitimate email. Whaling uses social engineering to trick people, convincing victims that they are representatives of a financial institute, such as a bank. Then attackers convince victims to transfer money into their accounts.

  • Whitelist / Allowlist

Whitelist or allowlist is a cybersecurity strategy in which you create a catalog of approved email addresses, IP addresses, applications, and domain names. Everyone on this list is digitally allowed to contact you. Meanwhile, everyone is denied permission to send emails or messages. This way, spammers and hackers cannot reach your network.

  • Wi-Fi

Wireless fidelity (Wi-Fi) is a technology that helps electronic computer devices (computers, smartphones, laptops, tablets) connect with the internet. It sends radio signals from a router to devices, translating them into usable data. Companies use Wi-Fi security protocols based on encryption technology only to receive protected data to keep their network safe.

  • Zero-day Exploit

A zero-day (0-day) exploit is a cybersecurity attack that targets a system’s vulnerabilities unknown to the program developer and injects malware. As a result, the antivirus vendor or software developer cannot mitigate the risk and protect their sensitive data.

  • Zero-Touch Provisioning or Deployment

Zero-touch provisioning or zero-touch deployment are interchangeable terms that refer to the automatic installation of organization-specific computer files, programs, and program settings. It also automatically updates the organization’s operating and security systems by uploading patches, fixing bugs, and implementing additional features.

What Are The 4 Pillars of Cybersecurity Awareness?

You must rely on the four pillars of cybersecurity awareness to ensure complete protection. The four pillars of cybersecurity awareness are:

Phishing Button

The phishing or phishing report button is an effective IT security tool that allows users to alert and report suspicious emails and network activity. When installed in the organization’s network, the employees only have to push this button to activate the cybersecurity system. This feature also helps identify whether employees are dedicated to the network’s cybersecurity.

IT Security Trainings

IT security training is conducted to teach employees what to do in real-life security crises. During these training modules, employees are provided with theoretical knowledge of cybersecurity. These models are then tested through various learning assessments. Providing this training pays off if the company’s network is under attack.

Infrastructure Assessments

Cybersecurity awareness also revolves around the workplace computers of employees. When giving cybersecurity awareness to workers, teach them how deeply malware or virus can infect a computer. Moreover, it informs which emails and links should be clicked on to maintain the security of the company’s network.

Attack Simulations

Attack simulations are fake cybersecurity attacks to raise awareness of cybercrimes. During simulations, you create false attacks that resemble phishing, smishing, and vishing attacks. These attack attempts are written in the “company’s language” to remain recognizable.

What Are The 7 Types of Cybersecurity?

Cybersecurity is a vast term that is a combination of several types of disciplines, which are:

Application Security

Application security is providing security measures for web applications and other software directly connecting to the internet. It prevents critical web application security flaws, such as malware injection, broken authentication, misconfiguration, bot attacks, and cross-site scripting.

Cloud Security

Cloud security focuses on securing cloud computing servers. This type of cybersecurity creates policies, solutions, and controls that protect an organization’s cloud deployment from external threats and attacks.

Endpoint Security

The Endpoint security model or zero-trust security model creates micro-segments around data packets. Companies can use it for securing end-user devices (desktop and laptop computers). This prevents ransomware and phishing attacks, as the security system is equipped with endpoint detection and response solutions.

IoT Security

Internet of Things (IoT) security seeks out vulnerabilities in IoT devices. As these devices connect to the internet, malware can use them as a pathway to infect an organization’s network. IoT security uses discovery, classification, auto-segmentation, and virtual patches to prevent IoT vulnerability exploitation.

Mobile Security

Mobile devices, such as tablets, smartphones, and laptops, can attract threats and malware from the internet and lead to corporate data. Mobile security stops these attacks and secures operating systems, reducing the risks of rooting and jailbreaking.

Network Security

Most cybersecurity attacks are directly carried out on the leading network as it contains sensitive data of the organization and its clients. Therefore, network security solutions identify and prevent attacks from infection the network. This cybersecurity type works on data loss prevention, network access control, and firewall generation while enforcing web use security policies.

Zero Trust

The zero trust security model creates a perimeter around a company’s operational systems to protect them from all external threats. This is also a drawback of this cybersecurity type as it does not protect from insider threats. Moreover, the network perimeters also dissolve rapidly with some attacks, leaving the network completely vulnerable. Therefore, you should use it to protect individual resources and combine them with micro-segmentation.

Wrapping Up

Cybersecurity is quickly becoming a much-needed profession because companies are shifting most of their operations to digital servers. This makes them vulnerable to viruses, malware, and other cybersecurity threats. When working as a cybersecurity expert, you will be working to protect servers and sensitive information. To effectively do this, you will also have to communicate with company heads for debriefing. Therefore, bookmark this glossary of cybersecurity terms to keep your knowledge updated.
