The article discusses various means of protection that can ensure the security of information systems (IS) of government agencies. When considering security measures to ensure the security of information systems, it is important to consider the possibility of successful implementation of distorted information. This makes it possible to identify the most significant threats and risks for the authorities in order to develop the most effective protection measures. Among the security tools under consideration will be access control systems, firewalls, antiviruses, intrusion detection systems and data encryption. Each of these tools has its own features and functionality that need to be studied and analyzed. By analyzing these security measures, we will be able to determine which of them may be most effective for ensuring the security of information systems in various scenarios. This approach will allow government agencies to develop and implement comprehensive and tailored security strategies, minimizing vulnerabilities and risks. The basic principles of the choice and implementation of security tools are also considered and the main domestic information security management systems are proposed, as well as the necessary organizational measures after the introduction of these tools. Thus, our analysis of IP security protections offers a study of various tools and helps government agencies make informed security decisions
