COMPUTER NETWORKS AND THEIR SECURITY

This article provides a detailed analysis of modern methodologies and technologies for ensuring network security. The main security elements of our research are cryptographic methods, network monitoring systems (IDS/IPS), VPN technologies, and security policies. This article examines the effectiveness and existing weaknesses of each technology. Cryptographic methods, such as AES and RSA algorithms, play an important role in protecting the network, but due to some threats and attacks, their effectiveness decreases over time. Although IDS/IPS systems are effective in detecting dangerous actions in the network, their high efficiency requires constant updating of the system. VPN technologies increase network security, but their use by some services without sufficient data encryption can pose a risk. The article emphasizes the importance of developing and implementing effective methodologies for ensuring network security.
