Cyber threats are multiplying - but so are our defense options. Attackers benefit from AI, exploit supply chain vulnerabilities and target personal identities. To keep pace with cybercriminals, organizations must understand current attack trends and adapt their security strategies.

An intrusion prevention system (IPS) is a security mechanism that protects networks from unauthorized access and attacks. It represents a further development of the Intrusion Detection System (IDS). 

The IPS detects attacks by continuously monitoring network traffic for suspicious activity. It analyzes network packets, protocols and attack signatures.

In contrast to passive systems, an IPS acts proactively to prevent or stop attacks. It automatically takes measures such as blocking network connections.

Real-time response: IPSs work in real-time to respond to threats immediately Detection methods: Use signatures of known attacks and advanced behavioral analysis to identify malicious traffic Logging: Recording events and activities and generating reports

The Norvethian Intrusion Prevention System protects web applications via an upstream security proxy server that filters all incoming traffic before a single request reaches the actual application server. The Admin Console fully controls this server via an encrypted SSH connection. 

The application server is not directly accessible from the public internet. Only the proxy server knows its address and forwards legitimate requests. This two-server approach completely isolates the application from the external network.
