2 Outline  Introduction  Snort  MySQL Server  CommView  Activeworx Security Center  IDS Simulation  Demonstration

March 29, Introduction  Intrusion Detection System (IDS) Collect data from network traffic coming into a system Tries to match it against known pattern of attack signatures Blocked the matched data and logged detail of attack into database  Snort A very popular and open source IDS Can be configured to run in Sniffer mode, Packet Logger mode, Network IDS mode A number of Snort Add-ons are available for monitoring Snort, analyzing result and writing Snort rules

March 29, Introduction  Simulation of IDS The following tools and OS are used in this Project Snort : Intrusion Detection System MySQL : Database Server CommView : Packet Generator & Sniffer Activeworx Security Center (ASC) : Snort’s Add-on.Net Framework : Additional software for ASC Desktop Windows XP : Operating System

March 29, Snort

March 29, Snort  WinPcap WinPcap is required to be installed to access Snort The latest WinPcap version is 3.1 for Windows 95/98/ME/NT4/2000/XP/2003 WinPcap is free and can be downloaded from Download the executable file “winPcap_3_1.exe” of size 456 KB and run to install

March 29, Snort  Snort is an open source IDS  Can be configured to run in three modes: Sniffer mode : Simply reads the packets off of the network and displays them./snort -vd Packet Logger mode : Logs the packets to disk./snort -dev -l c:\snort\log -h /24 Network IDS mode : Allows Snort to analyze network traffic for matches against a user-defined rule set and performs several actions./snort -dev -l c:\snort\log -h /24 -c c:\snort\etc\snort.conf

March 29, Snort  Install Snort version 2.4.3, available at  Download the executable file “Snort-243- Installer.exe” file of size 1.43 MB  Select “typical” installation that installs Snort at C:\Snort directory.

March 29, Snort  Important files and their locations Snort configuration file - C:\Snort\etc\snort.conf Snort executable file - C:\Snort\bin\snort.exe Snort log files are - C:\Snort\bin\log\alert.ids and C:\Snort\bin\log\snort.log., and Snort rules file (included project 10 rules only) - C:\Snort\rules\local.rules

March 29, Snort  Snort Configuration : The file Snort.conf has to be edited before running Snort The following steps can be taken to create a custom configuration - Set the variables for network Configure preprocessors Configure output plugins Add any runtime config directives Customize the rule set

March 29, Snort We took the following steps to configure Snort Set the HOME_NET variable as var HOME_NET /24 Set the RULE_PATH variable as var RULE_PATH c:\Snort\rules Uncommented the following lines: output alert_syslog: LOG_AUTH LOG_ALERT output log_tcpdump: snort.log include c:\Snort\rules\classification.config include c:\Snort\rules\reference.config

March 29, Snort Changed the database format as - output database: alert, mysql, user=root password=wazed dbname=ids host=localhost output database: log, mysql, user=root password=wazed dbname=tcpdump host=localhost Include the relevant rule sets (for this project) – include $RULE_PATH/local.rules Comment out all other include rules

March 29, MySQL Server

March 29, MySql Server  Download MySQL Database Server 5.0 from

March 29, MySql Server  Install MySQL Server

March 29, MySql Server  Configure MySql Server

March 29, MySql Server  Choose Detailed Configuration

March 29, MySql Server  Choose for Dedicated Server

March 29, MySql Server  Choose for Multifunctional Database

March 29, MySql Server  Configure Network support

March 29, MySql Server  Change root password

March 29, MySql Server  MySQL Connector/ODBC ODBC is a standardized API that allows connections to SQL database servers. ODBC usually is used when database independence or simultaneous access to different data sources is required. MyODBC 3.51 (installed in this project) is a 32-bit ODBC driver, also known as the MySQL ODBC 3.51 driver and it is available for download from:

March 29, MySql Server  Using MySQL Followings are some of the examples how to use the different databases and tables using commands from the DOS prompt : C:\mysql\MySQL Server 5.0\bin>mysql -u root –p Enter password: ***** Welcome to the MySQL monitor. Commands end with; or \g. Your MySQL connection id is 18 to server version: nt Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

March 29, MySql Server  Using MySQL: mysql> show databases; | Database | | information_schema | | aef | | aw_aef | | aw_asc | | aw_fw | | ids | | mysql | | sebek| | syslog | | tcpdump| | test | | vuln | rows in set (0.19 sec)

March 29, MySql Server  Using MySQL: mysql> use ids; Database changed mysql> show tables; | Tables_in_ids | | data | | detail | | encoding | | event | | icmphdr | | iphdr | | opt | | reference | | reference_system | | schema | | sensor | | sig_class | | sig_reference | | signature | | tcphdr | | udphdr | rows in set (0.00 sec)

March 29, MySql Server  Using MySQL: mysql> describe event; | Field | Type | Null | Key | Default | Extra| | sid | int(10) unsigned | NO | PRI | | | | cid | int(10) unsigned | NO | PRI | | | | signature | int(10) unsigned | NO | MUL | | | | timestamp | datetime | NO | MUL | | | rows in set (0.19 sec)
