Ddos prevention best practices

Developing this anticipation comes from facing the reality of being hacked. The real knowledge of the network must be something shared and accessible to all administrators so that the reports generated by monitors can be interpreted quickly and correctly. Practice 5 - Test yourself both locally and over the Internet When your network serves customers on the Internet you need to test its availability by simulating their activity.

Before making changes to the registry, you should back up any valued data on the computer.

Best Practices for Preventing DoS/Denial of Service Attacks

During this time, you may have grown comfortable with the high availability of your network and become complacent toward the potential for emergencies. Still, such an analysis would lack the business logic behind configurations and the needs of customers using the services on the network.

Often, it takes people far too long to realize that everyone in the company is working on the same problem. Practice 3 - Understand that success can result in complacency For your network team, it may have been a few years since a challenge of considerable magnitude has occurred.

While we do not want to say anything which could infer that hackers do anyone a service, to develop this intuitive awareness you need to "hack" your network yourself by imagining what a hacker would do to attack it.

Recommended Registry key configuration to thwart DoS attacks Caution: Without this type of training, you may do a disservice to your personnel by putting them in a position where they could damage their network and possibly their reputation unknowingly.

You can make the assumption that because you have not experienced serious network outages your current processes are fine.

While there is truth behind this approach, you must also consider the affect that simplicity can have on being able to support unforeseen problems. You can also use the Last Known Good Configuration startup option if you encounter problems after manual changes have been applied. The following registry key settings can be implemented to enable protection against DoS attacks: In order for this to work, this knowledge share must become part of the process of running your network.

With this method, both the common and uncommon configurations of your network are protected from the occasional error. The practice to develop is to go further in developing an inquisitive culture amongst your administrators and, in contrast, to discourage the rote or mechanical routine of processing network changes.

Keep this potential cause of emergencies on the minds of your new administrators and you will go a long way to encouraging that they investigate configurations before changing them.

You need to know that administrators in your segment are aware of the implications their changes have on other segments of the network, and who to contact at other segments when any emergency occurs.

Practice 7 - Keep people aware of old configurations and their purpose To develop and maintain an awareness of older, and often trusted, network configurations you need to pay special attention to your personnel changes during the development of your business and the expansion of your network infrastructure.

Granted, the error may be in a single segment, but the evidence that will lead you to diagnose a problem may be across your Intranet and the Internet. Considerations for Your Network The following information is provided to help you take a close look at your network and protect it from DoS attacks.

The lesson to learn here is to revisit your auditing trail and ensure that it encompasses both the details of your current changes and the reasoning behind your current infrastructure.

Practice 10 - Protect yourself against hackers Can you predict where a hacker will attack your network? To change this attitude, you must look for the strongest components of your network and conceive of scenarios where their failure transpires.

For any change to the network to be made, the document should be consulted and updated. Practice 6 — Your processes can harm you just like hackers Are your processes an enemy from within? Because it is unlikely that you will redesign your entire network infrastructure annually, configurations performed one year may stay around in your network until someone stumbles upon them.

In designing your network in a simplified manner, you leave yourself open to the repercussions of a simple mistake. Practice 2 - Create interdepartmental Standard and Emergency Operating Procedures One of the reasons why network outages take so long to diagnose is because many network admins begin by only looking for errors in their own segments.

It can be a difficult change to make because network administrators are so often engaged in firefighting comparatively minor issues within an overall network of high availability. Practices Details Practice 1 - Keep an audit trail that describes what was changed and why Locked in a file cabinet somewhere may be a document explaining the original purpose of your network design and its interdependencies.

When we simplify the way business information travels across our network, we need to consider whether or not we are serving our administrative needs second and our customers and users business first. You will be slow to respond because you responded to our own servers first.

A complex design can benefit the complex business needs you are trying to support.The best protection against DDoS attacks is a purpose-built device or service that scrutinizes inbound traffic before it can hit your firewall or other components of the IT infrastructure.
