There is an old saying that goes something like this: “all anyone really has is their reputation.”

As it relates to security, the same can be said for a server, or, more specifically, for an IP address. That is what other devices on the Internet use to communicate, be they cloud, local, physical, or virtual. Depending on the reputation of that IP address, a system can choose to trust it, block it or redirect to something else (like a honeypot).

When you are establishing the reputation of a person, you can ask other people what they think, sometimes even watch the person for a while. This model works for a small number of people. If you have to do this for a larger group you need to trust someone or something else.

Let’s look at the case of a large corporation’s HR department. They rely heavily on the background check to quickly build a reputation.

In our example of a large corporation, you could assume you might have to check 10s of reputations at once, sometimes 100s, rarely 1000s. But if we change a person to an IP address then we start at 1000s and can go to the 1,000,000s. NetScaler provides this to you via its IP Reputation Service.

The NetScaler IP Reputation Service provides a continuously updated list of malicious IP addresses in near real-time, providing an additional layer of protection and helping to reduce the burden on security teams. It automatically analyzes and correlates feeds from millions of global sensors in real-time and is updated every five minutes. NetScaler IP Reputation Service is FREE with the NetScaler web app firewall solution – no service contract and no yearly renewals necessary.

In today’s rapidly changing cyber landscape, a trusted IP address can become compromised in a matter of seconds. Depending on the security tools in play, that compromise can be mitigated seconds later. Humans can’t keep up with this speed, but NetScaler can.
