Trusted Systems in Network Security

 The term “Trusted system” means that it provides the user with an assurance that no malicious or harmful software affects the computer system. Network Security plays a vital role in many organizations, to keep the data safe and secure from being attacked by cyberattacks or malware. Now Companies are using cloud storage, Wireless network, and remote application, so the challenges in protecting them are also increased. Here the Trusted systems provide Multi-layered security (MLS) for securing the networks. The trusted applications will not allow any changes in the policy. In this article, the models of network security to have trusted systems are discussed here.

Network Security

Network Security is designed to protect the data and the network of our system or for business applications. It also protects hardware and software technologies. When using network security, it will oppose the threats to entering the system.

Multilayered Security

The main tool used by network security is Multilayered Security (MLS). The Multilayer approach targets the places that are more prone to cyberattacks. It will help the user by educating them about the threats and their causes, the antivirus software for security, and the process of removing the threat from the system. These are the benefits of Multilayered Security (MLS). By using this approach, we can improve the efficiency of the ability to defend the threats.

Responsibilities of Trusted Systems

The computer system comprises standard protocols and hardware devices then the Trusted Network architecture is implemented for safeguarding the systems. Some of the Security services it provides are user authentication, checking for regular updates of the system and policy-based access control, and also check the status of end devices. Traditionally the user can log in to the system without checking for any security protocols.

  • User Authentication − The Main Responsibility of the Trusted System is to grant the user to access the system based on the security protocol. When the user first connects, the hardware and the software are checked for secured connection. Based on the user’s details, the identification of the user is made and access is granted.
  • Role-Based Access control − The Algorithm allows only authorized persons to access using the permission and privileges and other systems are restricted.
  • Private Networks − When the system is connected to the trusted network then Virtual Private Network (VPN) is established. So, all the actions carried out in the system are captured.
  • Firewall − It is a type of device installed in the system to protect incoming data.

Examples of Trusted Systems

Some examples of trusted systems are −

  • Harmony Endpoint − It protects the system at the endpoint from threats such as phishing, ransomware, and malware.
  • Digital Guardian − It provides data protection and monitors data movement and also secures cloud storage.

Objectives of Multilayered Security

The main objective is to maintain the confidentiality of the data. The networks are secured according to preference or importance. For example, Top secret, Secret, Confidential, and not mentioned data.

To protect the network, there are two ways namely

  • Access Control
  • Threat Control

Data Access Control

In every Organization, Employees are given login credentials to make a secure connection. It is a method of identifying whether the right person has logged in to this work, based on the identification of profiles the associated ones with the company are authenticated. Then Finally letting the person access the data they want. Data Access control is the process of allowing the employees or the customers to use the data, cloud storage, folder, software, slide, or related information.

Models of Data Access Control

Logically they are further classified to access the data as Access control lists, Access capability lists, passwords, Group Policy, and Access matrix.

Access Control List

It consists of a table namely the spreadsheets, that check for the permissions attached to its object. It will either throw “Access denied” or allows the user to the spreadsheet in read-only mode.

Capability List

In this Data access control model, the permission is accessed by using a ticket, token, or key. Here the user is associated with the list of objects and actions.

Group Policies

In this, it provides an environment where all the data are grouped and managed from a single directory called the active directory. So, the time taken to go to each computer is eliminated. The pieces of information are stored in Group Policy objects by which we can configure the related data.

Threat Control

The Data access control protects the system from threats but not completely. For that, threat control is used, in which the hackers may get the credentials from the employers and access them.

To prevent this threat technologies like firewalls and load balancers are used. These technologies protect the network from the Denial of service (DoS) attack.

Many Organizations are moving to cloud storage, so the risks are also rising to secure the data. The Data access control and Threat control of multilayered security provide a solution to the network’s secured functions. Educating the Employees about the threats, and the causes helps them to be aware of the malware or attacks.
