Business Problem

Unauthorized traffic is a problem for many organizations because it often compromises their network's security, impacts the use of their existing resources and affects their customer service level agreements (SLAs). As the Internet becomes more expansive and complex, different kinds of trafic orginate from different types of servers and proxies. Name servers (NS), mail proxies, social media proxies, web proxies and even PCs posing as servers can send malicious traffic over networks. Even companies with existing policies and dedicated service providers experience intrusions, threats and unauthorized traffic. 

Organizations need solutions that successfully counteract these problems. Technology coupled with specific policies and continuous monitoring will help maintain a network's health and security. 

Who is Affected

Network and security managers of all sizes and types of organizations are affected by unauthorized and malicious traffic, but larger and more geographically distributed organizations such as governmental entities, critical network infrastructures and large enterprises are more susceptible to anomalous and unauthorized traffic. 

Solution

In order for organizations to keep their network safe, they must:

•  Determine and implement acceptable network policies and identify acceptable server types.
•  Continuously monitor network servers and applications.
•  Create a dynamic list of servers on the network.
•  Make corrections based on the policies set.
•  Create a whitelist (or blacklist) of rogue servers and applications or shut them down.
