7 layers of security:

1- Information Security Policies:

One of the main layers of information security is Information Security Policies, which gives users the assurance that you give a value to their information and do your best to protect them, the security plans for people who want to protect information must be prearranged and should have a step-by-step process to strengthen the security of your site.

In general, information security policies reflect the thoughts of the media and show all their efforts to protect information, through this layer of security , information can be secured against all existing threats.

This layer of security has 3 main types that we will mention in the following:

- Organizational (or Master) Policy

- System-specific Policy

- Issue-specific Policy

2- Physical Security:

This layer of security is always an important for many people, and they regularly provide facilities through which they can establish physical security to protect information, in the real world, if you have a valuable object, such as money, jewelry, documents, etc., you maintain this layer of security as fully as possible, for example, if you leave that valuable object in a safe place, or give it to someone who you trust, you are not worried about protecting them.

The same thing is also true for computers, generally, physical security is defined as the protection of hardware and software components, networks, and data from natural physical conditions and events, which may cause serious damage to an organization and the information contained in them, in other words, physical security includes all measures to protect all hardware, information and software available against theft, natural disasters, etc., in order to achieve this kind of security, you must pay attention to some tips which help you keep your information safe.

There may be different tips about the ways of establishing this layer of security which are different from each other, to establish this layer of security, you may choose a safe room with CCTV cameras, or restrict the access of different people to this room, which can also help you in protecting important information and other solutions that exists to ensure you that physical security is set up properly, it should also be noted that different there are different threats for this section, including, abnormal weather conditions, pouring coffee on the computer, people who target your information, etc., to establish security for each of these threats, certain principles are required.

3- Secure Networks and Systems:

This layer of security is very widespread, which includes all measures, equipment, etc., which cause the security of the system and the network to be integrated, and prevent any threatening factors from entering your system, and ultimately provide security for you.

Network security has 3 types, which we are going to discuss in the following.

- Physical Network Security:

This type of network security control is to protect information and prevent illegal access to the system.

- Technical Network Security:

This type is so important and protects all the data that is in the computer, including the one that is being transferred from the computer or the data that is entering the computer, in order to establish the security of this layer, you must pay attention to many points.

- Administrative Network Security:

As you know, the behaviors of users who have access to information, cannot be controlled, and you must provide facilities in advance, so that you can prevent any event that affects the security structure of the network, one of the things that can be done in this section, is restricting people's access to all information, which is an effective way to prevent a series of unfortunate events.

In general, in this layer of security , you can do the following:

- Network Access Control

- Antivirus and Antimalware Software

- Firewall Protection

- Virtual Private Networks

4- Vulnerability Programs:

Despite the spread of cyber attacks and loss of information which they cause, and the daily progress of hackers, security layers have received more attention from users, and they try to study and search in this field to have control over each layer and implement all the necessary strategies to protect their information, hackers are constantly scrutinizing the weaknesses of a system and use these weak points to attack the system and its information, so they get their desired results through them.

In this layer of security, you must pay more attention to the vulnerabilities of a system, all of these weak points have to be identified through various tools, then you should try to do your best to solve the problem because that weak points must be strengthened in order to increase security in general, so you can improve your system security by paying attention to all points.

5- Strong Access Control Measures:

This layer of security has a great impact on establishing security in general, and all the actions that are taken in this layer, ultimately, are aimed at controlling people's access to information, to achieve this goal, various solutions can be taken, including the solution of setting passwords which are hard to be guessed, which should include more than 8 characters, so it is hard for people to guess this password, as a result they cannot access your information easily.

This layer of security contains the following 3 types:

- Discretionary Access Control (DAC)

- Managed Access Control (MAC)

- Role-Based Access Control (RBAC)

6- Protect and Backup Data:

This layer of security helps you to have no worries about the stored information, and it is constantly recommended in this layer to provide backup information, so that in case of unexpected events, your information won’t be damaged and will be protected as much as possible, there are a number of ways you can get help from them in order to implement this layer properly, including keeping information in a safe place other than the current information system that helps you maintain your information safe. It should be noted that it is necessary to establish the security for the information from which you have made a backup.

7- Monitor and Test Your Systems:

In this layer, you should review all the actions you have taken and examine all the aspects, so that you can identify the possible dangers that threaten your information and system, in general, the system monitoring process helps you solve these problems and does not allow a problem to occur, which causes damage to your system or loss of your information.

To implement this layer, there are various tools which will help you achieve your goal, some of which we are going to mention in the following section.

- SolarWinds Server and Application Monitor

- NinjaRMM

- PRTG - OpManager by ManageEngine

- OpenNMS

- WhatsUp Gold

- OpenNMS

Last word:

In general, security layers are of a great importance and each of them has a separate world that in order to be able to create a flawless and integrated security, you must implement all the necessary strategies, we tried our best to provide you with some general information about each of the security layers, as a result, you can finally prevent hackers from accessing your information due to the fact that if they access your personal information, they will try to abuse them which is a big trouble for you, so you can prevent this from happening by mastering all the layers and not let your site be hacked , which help you not to create a bad user experience for your users due to the fact that they are not worried about the loss of their personal information.
