Single point of failure là gì


Every IT professional is aware of the serious nature of leaving network & security systems vulnerable via single point of failure (SPOF) weaknesses. A single point of failure can take down an entire system — everything from a single computer lớn a company-wide network. Measures are taken to prevent system failures & secure business information; yet many SPOFs are overlooked. Understanding what a SPOF is và how you can protect against it is pivotal in eliminating the critical risk of single point of failure vulnerabilities.

Defining Single Points of Failure

For a dictionary definition, TechTarget defines a single point of failure as: “A potential risk posed by a flaw in the thiết kế, implementation or configuration of a circuit or system in which one fault or malfunction causes an entire system lớn stop operating.”1 In other words, if one thing breaks, it all goes down.

It’s an IT Death Star.

Why This Is a Problem

Here’s an example where a single point of failure can bring work lớn a grinding halternative text. Let’s say there’s only one server phối up khổng lồ run a particular application. If that server fails, users are unable lớn access the application. This single point of failure (the server) has brought access to the application khổng lồ a halt. People can’t work without access to the network. TechTarget reports: “a single point of failure can compromise the availability of workloads — or the entire data center — depending on the location & interdependencies involved in the failure.”2 Productivity suffers when a system with SPOFs goes down. Security is compromised.

To Add Insult to Injury

Not all businesses can afford extensive IT departments, equipment and redundancies. The threat of SPOFs is greakiểm tra in these businesses.3

Protecting Against SPOFs

The first step in protecting against SPOFs is identifying where the problems are. In making sure your network is secure, you should be looking at these three main areas: hardware, services/providers và people. For each of these categories, IT professionals should look for any data that isn’t backed up, any hardware or software systems that have sầu no redundancy and any unmonitored devices on the network. For every part of your network, identify what you would stand to lớn chiến bại if this particular “link” were lớn go down.

Another option khổng lồ identify areas of weakness is to hire outside help to lớn identify potential SPOF vulnerabilities. Groups or individuals with experience in this area can help immensely.

Even Security Tools Can Be SPOFs

Even security tools can be SPOF hazards! Security tools designed for inline threat prevention, such as intrusion prevention systems (IPS), website application firewalls (WAF) và advanced threat protection (APT) solutions are susceptible khổng lồ failure during power failures, link or NIC failure, when they bloông xã good traffic, or when they pass bad traffic. Redundant security measures are a must, because even the tools designed lớn protect your network can fail.

So, what options do IT professionals have sầu if security tools can be SPOFs?

One option is khổng lồ adopt an inline bypass solution.

Gigatháng Inline Bypass

An inline bypass solution eliminates the single point of failure in inline security systems by allowing traffic to continue khổng lồ flow through a fail-safe access port. Inline Bypass is a svào option for those looking khổng lồ protect against security SPOFs.

How It Protects Against SPOFs

More specifically, Gigatháng Inline Bypass protects against SPOFs in the following areas:

Heartbeats. Gigatháng Inline Bypass issues heartbeat packets that verify the tool is passing traffic. If the heartbeat has trouble going through, the bypass can react accordingly. By fine tuning the heartbeat settings, network engineers can ensure that a tool does not impact network latency requirements. Physical bypass protection. In the sự kiện of a Gigatháng visibility node power failure, the integrated physical bypass protection provides fail-to-wire resiliency for the network. In other words, the node is not itself a SPOF.

Inline Flow Mapping™. A healthy tool may become a SPOF if it is trying too hard khổng lồ inspect too much traffic. By selectively forwarding the most important traffic for inspection and bypassing low-risk traffic, the Inline Bypass solution helps tools operate at peak performance.

Eliminate the Risk of Single Point of Failure in Network Security

Gigatháng Inline Bypass protection helps eliminate the risk of single points of failure in network security systems. It is one of the most powerful, intelligent tools out there. With industry-leading traffic intelligence monitoring và physical/logical bypass protection, ensures a single point of failure in one area of security won’t take down the entire network. With Gigatháng Inline Bypass, the risk of a single point of failure in network security is nearly eliminated.
