Modern Network Security An Overview, Threats, and Prevention

As life revolves around digital services and wearable gadgets, web security is important in securing data and away from potential dangers.

Explore this Network Security Guide to know more about the possible threats and preventive measures.

Real World Statistics

While network security remains a prominent concern to individuals and organizations, major businesses are impacted by threats in the real world.

The numbers stand as a piece of evidence to safeguard the network and prevent the dangerous theft of vital information.

  • According to a survey, more than two Lakh cyber fraud incidents are reported in the first two months of 2022. Strangely, only some of them have been resolved to date.
  • Organizational cyberattacks see an increase of 32% year-over-year, according to Check Point Research.
  • Most organizations are significantly affected by Ransomware attacks, with an unbelievable rise of 59% year-over-year.
  • Spain’s radioactivity alert network (RAR) is affected by cyberattacks wherein attackers attempted to delete the entire web application, suspecting 300 sensors (June 2021).
  • According to IBM Reports, the Healthcare sector is majorly affected by data breaches leading to nearly $1 million in financial damages since 2020.
  • Out of 550 organizations, 83% experienced at least one data breach in operations.
  • An 11% decline in revenue due to a critical cyberattack affects tenet in 2022.

Top Network Security Threats

Businesses and young entrepreneurs may face any security threat as attackers have multiple ways to damage business operations. Check out the top and the most common network security threats.


A form of ransomware malware threatens to permanently control access to or publish the victim’s personally identifiable information unless a ransom is paid.

The biggest threat to networks is undoubtedly ransomware since it delivers attackers the most value for their money and has a low likelihood of being discovered.

Due to its obscurity and possibly large payment, ransomware has become one of the world’s most lucrative criminal industries.

More complicated malware implements cryptoviral extortion, although other simple ransomware may just restrict the system without damaging any files.


Software containing malicious activity classified as spyware aims to obtain data on a business or individual and transfer it to a third party inappropriately.

It has the opportunity to monitor which websites a person visits and gather confidential credit card information and credentials.

However, spyware that is operated maliciously is hard to distinguish since it is concealed in the computer’s system files.

Phishing attacks

Attacks referred to as “phishing” include sending error information that seems to be from a trustworthy source.

A person is misled into opening an email, instant message, or SMS by an attacker who pretends as a trusted provider.

It has been designed such that the information appears to have originated from a credible source.

Phishing is commonly implemented as a part of broader cyberattacks to establish a base in industrial or governmental networks.

In addition to experiencing substantial economic losses, a corporation that is the victim of such an attack frequently experiences a loss of its market share, prestige, and customer confidence.

Botnet Attacks

Botnets are clusters of Internet-connected spamware machines that rapidly and correctly conduct our everyday activities.

They are built to transport certain malicious operations, including keylogging, bombarding, and distributed denial-of-service (DDoS) threats.

Each device in a botnet is described as a “zombie” since neither it nor its operator knows that the device is automatically performing terrible actions.

Through spam campaigns, botnets typically disseminate Trojans and other malware. Although all botnets are competent and confident of causing serious damage, some have a far more dangerous impact than others do.

Computer Virus

Computer viruses interfere with systems, lead to serious functional problems, and cause loss of information and leakage.

Computer viruses are made to transmit between systems and programs is an important fact to be aware of.

Its poor performance, redundant pop-up windows, and self-execution of applications on a computer or in an internet browser can identify a computer virus.

Computer viruses are a serious worry for individuals around the globe since they can damage profitability by trillions of dollars.

How to Prevent Network Attacks

While network attacks can be made at any given point, certain important steps can help you avoid harmful threats.

Check out the below ways regarding how to prevent network attacks and save your hard-earned money through it.

#1. Install an SSL Certificate

SSL protects and transmits sensitive information shared between the web server and browser using encryption across open networks to maximize the quality of confidentiality.

By utilizing three independent layers of security—encryption, data integrity, and authentication—SSL certificates resist data spying and MiTM attacks.

It activates the HTTPS protocol when implemented on a web server, enabling secure connections from a web server to a browser.

Therefore, it is necessary to buy SSL to secure your website and enjoy encrypted transactions.

#2. Set Strong Passwords

A secure password should be challenging for a person and a computer program to comprehend.

The objective of a password is to guarantee that only authorized individuals can access it. The use of dictionary terminology should be avoided.

Using the same password across all of your platforms might be hazardous because it makes it simple for hackers to access your data.

Never use the same passcodes twice, and modify them periodically. Try to include upper- and lowercase characters, numerals, and symbols.

#3. Access Control

Who is authorized to access and use firm information and resources is set by access control, a central component of data security.

Control over who can access your network is crucial because one of the attacks can be physical. Controlling who has access to the systems is significant.

Anyone can easily access or infect the entire infrastructure by approaching the workplace or business and connecting a harmful device with contaminated data.

#4. Create Employee Awareness

An insider threat can occasionally make an external threat successful. Your workforce may be the biggest liability in the data protection chain.

Hackers may send spam emails posing as employees of the organization and demand personal information and access to certain files.

Set strong policies and procedures in the light of network security to ensure employees are not only aware but also alert about the possible threats.

#5. Update Software

It is more challenging for cyber criminals to identify weak links in the system to target when the software is modified and up to date.

The systems are better protected from assaults when individuals apply software patches and updates as recommended.

Individuals can take preventative precautions by reading the terms of agreement before downloading and installing, eliminating pop-up commercials, and only downloading software from trustworthy sources.

Additional Ways to Prevent Network Attacks

  • Individuals should undergo training on how to recognize attempts to access sensitive information from them via emails, phone calls, or other channels.
  • It is crucial to keep anti-malware software up to date to safeguard information systems from the greatest malware attacks.
  • One of the easiest ways to protect yourself from cyber threats is to place your networks behind a firewall.
  • The responsible thing you can do is to secure and encrypt Wi-Fi networks.
  • You can lessen the number of attack when you provide unique login credentials to each staff member.

Final Word

While it is crucial to safeguard the organization from potential hackers and cybercriminals, getting started with defending your company from cybercrime and cyberattacks can be challenging.

Trust the professionals for effective network security who work on your solid vision towards high-end network safety.

All you require is a workable solution to prevent network attacks, data theft, and loss of vital business operations.
