Learn about the security-relevant characteristics of IDS and IPS data and how it can contribute to improving network security.
- [Instructor] As you know…firewalls log rejected packets as errors.…On the other hand,…IDSes or IPSes produce security alerts as their data.…They use signature files that define…what should be examined in packets…to recognize an impending attack.…More recently offenders are attempting…to identify intrusion attempts…by comparing the normal and abnormal behaviors…of a network under watch.…In fact, a newly emerging approach seeks a combination…of both signature and behavior-based detection.…
To accomplish behavior-based detection,…IDSes or IPSes need to be able to analyze…a large quantify of data.…Coincidentally many breakthroughs…in information technology and data science…such as Cloud computing and big data analytics…are now occurring.…And they're acting as enablers used…for more efficiently implementing…the behavior-based IDSes and IPSes.…Cloud computing is essential to hold and process…an enormous amount of packets captured by IDSes and IPSes.…
To improve the processing efficiency in the Cloud setting,…distributed computing and file systems like Hadoop and Spark…
