Today, the use of computer systems and Internet networks is prevalent. Therefore, these valuable systems and their information, which are very important in this century, must be protected.

Unfortunately, various harms threaten our information security; So we need a smart and robust protector against these dangers.

Cyberattacks are attacks carried out by computers and computer networks to disclose, destroy, alter or steal and gain unauthorized access to information.

Governments, individuals, or organizations carry out these cyberattacks. Unfortunately, these attacks can cause significant damage and destroy the credibility of individuals or companies.

Indeed, the vulnerability of the systems makes it easier for these attackers. Therefore, using multilayer security is very necessary and wise.

 Today we talk about multilayer security, its importance, and how to create it. So stay with us.

The importance of multilayer security

About seven billion people worldwide are present on the web and enjoy this fast and attractive communication space. Therefore, they need security, which means that their information is honest, confidential, and accessible. But unfortunately, in addition to all the fantastic benefits of this magical space, there are many dangers and risks.

The widespread violation of users’ privacy in cyberspace and the misuse of people’s identities in this space cause many scams. Cyber-attacks are evil and can completely shut down a computer. Other targets include stealing information and setting the stage for a larger attack. Statistics show that only 40% of businesses exposed to these attacks have been able to recover, and the rest have been shut down within six months.

If you question why hackers carry out such attacks, answer this question: Why do thieves steal ?! Financial needs, psychological problems, evil nature. Hackers also commit such acts of sabotage for various reasons, and the number of these attacks is increasing every day.

Just as a crime in the real world comes in many forms, including wallet, pickpocketing, extortion, cyber-attacks come in many shapes.

A high number of cyber police cases are related to banking, cybercriminals, and cyber revenge. All because of the safety deficiencies of these systems.

So, it is necessary to create a strong shield against these dangers to get the most out of this environment with the least damage. Because in the 21st century, old battles have given way to a new style of fighting and profiteering. It is a scientific battle. So, it is essential to take the necessary and smart measures to deal with various threats and cyber attacks.

 Types of cyber threats

Internal and external attacks:

Cyber threats can be internal. It is done from within the organization and by one of the members, or it is external. What should be done now?

 Indeed, by closing the various ways of intrusion, you will not achieve sufficient security. You can not stop the combined attacks carried out through multiple ways such as phishing, middle man attacks, or attacks with the help of malware and loggers and spam, etc. We recommend using a multilayer security system.

Multi-layered security areas

People who attack your information systems. They first look for security vulnerabilities in your system and then quickly enter your system.

Defense against attacks is related to three areas:

  1. Physical
  2. technical
  3. administrative

Therefore, it is necessary to consider protection programs for all three areas.

Security layers

We can protect pieces of information in various ways, which, of course, work together and complement each other, forming multilayer security.

The remarkable thing is that these different layers of security and strategies unite and integrate and mutually destroy and repel saboteurs’ actions. They complement each other and all come together to achieve the same goal and cover each other’s shortcomings because each has different strengths and weaknesses.

The five layers of security are:

  1. Inactive attacks
  2. Endpoint security
  3. Data security
  4. Security of the local environment
  5. Network security (antivirus, application security, data loss prevention, email security, behavioral analysis, firewall, network sharing, mobile security, security information and data management, virtual private network)

Things to take care of:

Data security provides more protection against harmful downloads.

Given the importance of data retention, it is necessary to identify and implement the following accurately:

  1. Controlling the use of data and protecting its circulation: means who has the right to access the system and information.
  2. Data protection: means preventing the destruction of information or its dissemination. In this way, the story remains quarantined, protected, and confidential.
  3. Classification and archiving of information: It means that the data is marked and stored. It gives them access.
  4. Encryption of sensitive and confidential data: not to hinder the use of this information.
  5. Secure file sharing: which causes user cooperation and file sharing, and synchronization and distribution are also supported.

Multilayer security or in-depth defense

Layered security refers to security systems that use several components and levels to combat these cyber-attacks. Of course, it also means in-depth defense, in which several strategies and resources are used to slow down, delay, or block the threat to neutralize and neutralize it completely.

Multilayer security performance

Unfortunately, no security way can fully resist various attacks, but it can minimize them.

But these layers, like a stronghold with several strong walls, surround your information all around. It uses several technologies that have different strengths and weaknesses. These barriers make it difficult for cybercriminals to access your data.

This strategy can include a spam filter, a web filter or anti-malware, and so on.

Use of cloud computing

Multilayer security of your system and information protects against various attacks in different ways. This work acts by blocking traffic inside the cloud. The cloud computing company manages all incoming and outgoing emails and web traffic of the company and the client. The provider of these cloud services scans, examines, tests, and transfers or blocks traffic.

It is wise to use cloud services and get help from them; Because costs such as infrastructure costs and bandwidth are shared between customers. The same is valid for mass security, meaning that security enhancements can be made for all cloud users.

It is enough for companies to find a reliable cloud service provider to protect their small or large business and manage their data and protection.

High-volume attacks require fast and accurate management; Because it has done its job quickly and before the device can filter it. Therefore, it is necessary to block traffic inside the cloud with multilayer security so that these attacks do not reach the systems.

Cloud Security

In short, cloud security does the following steps to protect user information:

In the first stage:

Threats are detected and investigated and prevent damage to users’ information because they return automatically.

In the second stage:

Threats are analyzed, and threats and suspicious behaviors investigate to take appropriate action.

In the third stage:

Sound protection and counter-threat. That is, it automatically backs up data against suspicious and unknown activity.

In the fourth stage:

Backup and restore are done. Thus, even if a malicious object succeeds in entering and performing its action, the data needs to be encrypted and backed up and restored to its original state and malware to be returned.


So far, there have been several attacks on computer networks, all of which divides into three main groups:

 Detection attacks: In this type of attack, attackers collect and identify information to destroy and damage them.

 Access attacks: In this type of attack, the primary purpose of attackers is to infiltrate the network and gain access to email addresses, information stored in databases, and other sensitive information. 

Services disabled attacks: In this type of attack, attackers try to harass to gain access to all or part of the facilities available on the network for authorized users.

 The above attacks are carried out in different forms and using various technologies. Sending large amounts of unrealistic data to a machine connected to the Internet and creating false traffic on the network are examples of this type of attack. All of these attacks can cause irreparable damage to people and their businesses.

Therefore, we recommend that you stop using traditional security tools and use multilayer security to avoid various threats. Because multiple security solutions include prevention, identification, and treatment and controls the situation well. Using a cloud computing system will help you and your business in this regard because it takes on security and brings you peace, security, credibility, and cost savings.
