An IT specialist is consulted about setting up a peer-to-peer network. What would the specialist say about security risk in this type of network?
A. Peer-to-peer networks limit outside network access, so there is no security risk.
B. Peer-to-peer networks use a central server to provide security measures.
C. The peer-to-peer network is the most secure network available.
D. There are many separate points of access that pose a security risk.
The correct answer and explanation is:
The correct answer is D. There are many separate points of access that pose a security risk.
In a peer-to-peer (P2P) network, each device or node acts both as a client and a server, sharing resources directly with other devices. This setup leads to several potential security concerns. Unlike centralized networks, which rely on a single server to control and secure communication, P2P networks have multiple points of access because each device can communicate with any other device. This decentralization increases vulnerability because if one device is compromised, it can potentially affect the entire network.
Each device in a P2P network needs to be properly configured to ensure security, as there is no central authority monitoring or enforcing security policies. Without proper security measures, such as firewalls, encryption, and antivirus software, devices in a P2P network can easily be targeted by attackers. In addition, the lack of centralized control means there is no single point to apply consistent security protocols or updates, which can leave the network exposed to various threats like malware, data breaches, and unauthorized access.
Furthermore, P2P networks are often used for file-sharing, which can open doors for malicious files to be shared across devices. Since devices are directly connected to each other, once one device is infected, it can spread malware to others within the network.
To minimize the risks in a P2P network, it’s crucial for each device to have strong security measures in place. This includes implementing robust authentication, encryption for data transmission, and ensuring all devices have up-to-date antivirus and firewall protection. While P2P networks can be efficient for certain uses, they require more attention to security than other network types.
