Construction of an information security system (ISS)

[mehadihasan123456]

The information security system of an information system is a set of technical and organizational measures designed to ensure the security and confidentiality of information stored and processed within a given information system. The main goal of such a system is to prevent unauthorized access, leakage or damage to data, as well as to minimize the risks of security incidents and other threats to information security .

The information security system must be developed taking into account the requirements of legislation and the specific needs and threats that the information system faces or may face. It is maintained and updated over time to adequately respond to new threats and technological developments. The main principle is to create a complex barrier to unauthorized access, ensuring the confidentiality, integrity and availability of data in the information system.

The full list of requirements for the information security system of an information argentina email list system, depending on its class, is listed in order No. 195 of the OAC dated November 12, 2021 .

The process of building an information security system includes the following stages:

Threat and risk analysis. Evaluation of existing threats and vulnerabilities of the information system, as well as identification of potential risks and consequences of security breaches.
Developing security policies and strategies. Defining the basic principles, goals, and strategy for ensuring system security. This includes establishing rules for access, encryption, authentication, monitoring, and other security measures.
Selection of technologies and tools. Selection of necessary tools and technologies for implementation of protection, such as firewalls, antiviruses, intrusion detection systems and others.
Development of security measures. Creation of specific security measures and policies, including setting up access rights, data encryption, authentication mechanisms, backups, etc.
Implementation and configuration. Implementation and configuration of selected technical means and software tools in accordance with the developed security measures.
Training and awareness. Train employees and users of the system in security rules and measures, and inform them of current threats and protection methods.
Monitoring and Administration. Installation of monitoring and administration systems for continuous monitoring of system security, detection of anomalies and response to incidents.
Security audit. Periodically check the effectiveness of security measures, identify new threats and adjust the security strategy.
Ensuring compliance. Continuous compliance of the information security system with legislation and security standards.
Incident Response: Developing plans to respond to incidents and recover from attacks, breaches, or other security breaches.
Data encryption. The use of encryption to protect sensitive data in transit and in storage. Encryption provides an additional layer of protection against unauthorized access to sensitive information.
Physical security. Ensuring the security of physical equipment and access to server rooms, data centers and other infrastructure resources.
Vulnerability management. Regularly updating and patching software, operating systems, and other system components to eliminate known vulnerabilities.
Backups: Regularly back up your data and system to enable recovery from incidents such as attacks, failures, or leaks.
Authentication and authorization. Use strong authentication methods (passwords, two-factor authentication, etc.) to establish the legitimacy of users, and strictly manage their access rights to resources.
Network security. Protecting network infrastructure, including network devices (routers, switches) and applying methods to prevent attacks, interception of data, and maintaining network privacy.
Web Application Security. Protect web applications from vulnerabilities such as injections, cross-site scripting (XSS), cross-site request forgery (CSRF) and others.
