How does peer-to-peer networking impact network security?

Peer-to-peer (P2P) networking fundamentally alters the way resources are shared and accessed between computers, significantly impacting network security. In a P2P network, each participant (or peer) has equal responsibilities and capabilities in sharing resources. This decentralized approach can lead to moderate security levels due to several factors.

In traditional client-server models, security can be more easily enforced and managed through centralized controls, allowing for robust authentication and access permissions. However, in a P2P environment, each peer must maintain its own security measures. This can result in varying levels of security across the network, as not all users may implement the same standards or practices. Without central oversight, it becomes more challenging to establish consistent security policies, leading to potential vulnerabilities.

The decentralized nature of peer-to-peer networking means that there is no central authority managing security. This can expose individual peers to risks, including malware or unauthorized access, if they are not vigilant. Since the security relies on the practices of each peer, we can say it offers only moderate network security, as there are opportunities for weaknesses in this model.

Therefore, while peer-to-peer networking provides a flexible and convenient way to share files and resources, it does not inherently offer higher levels of security and often requires more
