SECURITY While SNEZ is tested with web vulnerability scanners, do not allow SNEZ to be accessed from the Internet or an untrusted or insecure network. REQUIREMENTS and PRE-REQS Ubuntu (tested on 14.04) or RedHat-based (tested on Centos 6) Linux. Versions prior to 1.11 provide installation scripts and program code for Centos and RedHat only. Snort, Apache, MySQL, PHP. For https connection (default), mod_ssl and openssl. README.SSL contains information to a aid in the generation of a digital certificate. When configuring Snort, output type must be MySQL or barnyard2 to MySQL. NEW INSTALL (See below for upgrades) Create SNEZ database and install package- 1. mkdir /opt/SNEZ 2. cd /opt/SNEZ 3. cp [download location]/SNEZ-[ver].[rel].tar.gz ./ 4. tar -xzvf SNEZ-[ver].[rel].tar.gz 5. cd SNEZ-[ver].[rel] 6. ./SNEZcreate or bash SNEZcreate (This will create and populate your SNEZ db. Supply password for root@localhost when prompted; then supply a password for access to your SNEZ DB when prompted. You will enter this password in the config file in the next step). 7. vi ./SNEZconfig.php. Add the SNEZ database password selected in the previous step to the line SNEZ.password= Modify other parameters as needed, especially your sniffer interface (See CONFIG FILE later in the README) 8. ./SNEZinstall or bash SNEZinstall (Answer prompt with C for Centos, else Ubuntu is assumed) 9. Create logins and populate malware active ip list- a. In a browser- http://[ip address of server]/SNEZ/SNEZlogin.php b. Login as 'admin' using password of 'admin' c. Click on the Admin Functions tab and add an administrator that can add users (be sure to check the box) d. From the browser, log off and log on with the new administrator id from step 3. e. Go to Admin Functions and delete user admin. 10. Click on the box to load malware active ip list from malwaredomainlist.com 11. Use visudo to make the additions and changes so certain root commands can be executed. (Caution! Read the sudo and visudo documentation. Mistakes here can render your system inoperable. Never edit the sudoers file with vi or another editor. You skip this if you don't want to use the tcpdump or logrotate-on- demand capabilities of SNEZ, or are uncomfortable making the changes, or concerned about security implications of allowing a non-root user running tcpdump or logrotate). hostname (get hostname of your system) visudo (add the following lines, adjusting for your system appropriately; some systems may use apache as http server user, Centos for example) www-data hostname=NOPASSWD:/usr/sbin/tcpdump (substitue your host name for hostname) www-data hostname=NOPASSWD:/bin/ps www-data hostname=NOPASSWD:/bin/kill www-data hosthame=NOPASSWD:/usr/sbin/logrotate (comment out the following lines if present) Defaults requiretty Require !visualpwd !wq (or q! if you make mistakes and want to start over) CONFIG FILE (after install, the config file can be changed at any time, and then run SNEZconfiginstall from /opt/SNEZ/SNEZ-v.r.m) Settings in the SNEZconfig.php file- [settings] encrypt = none none or an existing, installed php hash function for password NOTE: if you change this on a running system, login first, run SNEZconfiginstall, and immediately add new users https = enforced all connections https; change to unenforced for http (NOT RECOMMENDED) inactive = 900 page timeout SNEZ.password password to the SNEZ database chosen at install time; must be set gmt= -5 GMT offset; default to USA Eastern max.rowlimit=10000 default maximum db rows read before page displayed dns.rowlimit=1000 default max db rows read before page displayed when DNS resolution used;(can be lowered for speed) summary.rowlimit = 10000 number of db rows to read before fully collapsed summary view php.max.execution.time = 120 overrides php.ini max execution time sniffer.interface = eth1 sniffer interface for optionaluse of tcpdump (*Note) min.user.pwd.len = 8 minimum password length for users pwd.complexity = strong default is strong, letter, number, caps, special chars; can change to simple whois = SNEZdoc.php?page"="whois whois or reputation lookup site; select your personalfavorite * (whois2 through whois9 can be added to for up to 10 reputation or lookup sites) * You can cut from the SNEZ page and paste into the lookup site, however, keyword substitution is also provided for ip address and domain lookup information. Use keyword SNEZip to substitute ip address, and SNEZdns for domain lookup. You will need to manually visit the site to determine the path and the proper location in the URI for the parameters.
