Find Your Security Vulnerability Before Hackers Find It For You

Every Network Has A Security Vulnerability - Where Is Yours?

One of the top questions on the minds of network security personnel is "how do I reduce my security risk?"  Even for smaller organizations this is important because every network has a weakness.  But, do you know WHERE you are the most vulnerable?  Wouldn't you like to fix the problem now, before a hacker exploits it?

Here is a three-point plan that works to expose intrusions and decrease network security risk:

  1. Reduce as many attacks from entering the network as possible
  2. Find and quickly remediate intrusions that that are discovered within the network
  3. Periodically test your defenses to make sure they are actually detecting and blocking threats

Network Security - It All Starts With Prevention

Inline security solutions are a high impact technique that businesses can deploy to address security threats. These solutions can eliminate 90% or more of incoming security threats before they even enter your network. While an inline security architecture will not create a foolproof defense against all incoming threats, it provides the crucial data access that security operations (SecOps) teams need to make the real-world security threat load manageable.

It is important to note that an inline security solution is more than just adding a security appliance, like an intrusion prevention system (IPS) or a web application firewall (WAF). The solution requires external bypass switches and network packet brokers (NPBs) to access and deliver complete data visibility. This allows for the examination of ALL data for suspect network traffic.

Hunt Down Intrusions

While inline security solutions are absolutely necessary to lowering your risk for a security intrusion, the truth is that something bad will make it into your network for whatever reason. This is why you need a second level of defense that helps you actively search for threats. To accomplish this task, you need complete visibility into all segments of your network.

At the same time, not all visibility equipment is created equal. For instance, are your security tools seeing everything they need to? You could be missing more than 60% of your security theats and not even know it. This is because some of the vendors that make visibility equipment (like NPBs) drop packets (without alerting you) before the data reaches critical security tools, like an intrusion detection system (IDS). This missing data contributes significantly to the success of security threats.

Keysight Technologies has the solution to the problem. Our taps, bypass switches, and NPBs provide the visibility and confidence you need that you are seeing EVERYTHING in your network - every bit, byte, and packet. Once you have this level of visibility, threat hunting tools and security information and event management (SIEM) systems can proactively look for indicators of compromise (IOC).

Stay Vigilant and Constantly Validate Your Security Architecture

The third level of defense is to periodically validate that your security architecture is working as designed. This means using a breach and attack simulation (BAS) solution to safely check your defenses against real-world threats. Routine patch maintenance and annual penetration testing are good security techniques; but they don't replace weekly or monthly BAS-type functions. For instance, maybe a patch wasn't applied or was applied incorrectly - how do you? And penetration tests are only good for a specific point in time. Once a few weeks or months have passed, new weaknesses will probably exist. And crucially, were the right fixes applied if a vulnerability was found? For these reasons and more, you need to use a BAS solution to determine the current strength of your defenses.
