Easy Practices to Get Rid of DoS Attacks

By CIOReview | Monday, September 26, 2016

Network breaching has been one of the favorite pastimes of hackers. On the other hand, enterprises are continually in pursuit to prevent the illegal Denial of Service (DoS) attacks which are encountered frequently. Some organizations recognize such attacks and modify their system to make it immune, while others just dump their networks. Preventing DoS attacks has been a great concern of enterprise network administrators and only the best practices, written below, can make help in relinquishing them:   

Compile and keep track of audit reports: An enterprise network entails various necessary changes in the designs and these are updated in the audit reports. During any network collapse, these compiled reports can walk through enterprise network operators through the details of current changes made and its purpose. This method can also prevent network configurations form occasional errors.

Develop standards or Emergency Operation Plan: An enterprises biggest concern is the outage which occurs occasionally without any alerts. When network cripples down, system administrators begin to identify the cause of breakdown which takes a longer time as the same procedure needs to be completed for every failures encountered.

The important lesson to be learnt here is, instead of following all the procedures as a standard practice—Standard Operating Procedures (SOPs) and Emergency Operating Procedures (EOPs) should be developed. This will reduce the time taken to identify the errors by specifically designing the operating plans.  

Be ready to dodge a bullet: Encountering smaller problems and succeeding in eliminating them will make the systems and network team complacent. But this complacency will come to an end during any major emergency as network administrators will be engaged in other minor issues running in the network. To build a secure network it becomes vital for network controllers to envisage the areas where breaches can’t reach and conceive areas where failure occurs.

Know the network configuration in detail: Apart from network monitoring, it is very important for a network administrator to know about the configuration in detail. Also by knowing the network configurations, reports generated can be shared and accessed swiftly between network administrators.

Test the network: As the created network serves the customer, it must be tested locally within the enterprise and also tested online. The result may draw a clear picture of what problems the customer is facing and this may help to rectify the error to give better customer experience.  

Check whether process can harm like hackers: Frequent skeptical evaluation of the process helps to skip the harmful effects of the network crashes. There are many concepts that an enterprise can implement to their existing network system—design for failure. The fundamental of design for failure is to modify a system according to the breakdowns encountered.

Record old configurations: Develop and maintain the records of the changes made in the old network configurations. These records will help to gain settings whenever required in the future and the records can be retained by auditing annually.

Unleash the hacker in you: In order to become proactive, companies should conduct networking hacking drills to measure prominence of their networks. This ironical practice will allow admins to measure their network’s vulnerabilities and weak spots and take the necessary steps to put an end to the cyber breaches.
