This may not be the right forum ( if so please point me to the right
location) but here goes:
I am working on a project where we are integrating a SIEM into our
environment and I need to create a monitoring and alerting standard.
If I can explain some more:
- There are specific "isolated" suspicious behaviour that we would
want the SIEM to alert on e.g e.g Admin logon at specific times of
the day, mid night for instance.
- There are also specific "combination" of suspicious behaviour that
we should alert on: e.g
I have a simple 3-tier web app behind a firewall, and four event
sources for SIEM: a firewall, system events from
whatever daemon running on your servers and an (D)IDS
Event 1 : IDS says I have an SQL injection. Taken alone, this is
false, it's just an attempt at an SQLi and I have no idea whether or
not it has succeeded.
Event 2 : system daemon says I have a file creation on a temp folder
in your DB server
Event 3 : system daemon says said dropped file is ran under the DBserver user
Event 4 : firewall says I have outbound connection created to blah
server on port 80
Event 5 : IDS says blah server is hosted on an IP with a bad
reputation (I assume that's the D in DIDS)
Based on the above, I would say that i have been hacked.
The query that I have is: are there specific set of malicious
behaviour or "use cases" similar to the above that I can use as the
basis for configuring my SIEM to detect against malicious patterns of
behaviour.
Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate. We look at how SSL works, how it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
