IIS-IP-block

This script uses a custom 404 page that logs the IP address and amount of times it has loaded the 404_error.pl .If someone loads the 404 page 3 times in succession their IP address is logged to the banned_ip_list.log file. Every 60 seconds build_deny_list.pl opens the banned_ip_list.log file and gets the IP address to block. It then generates some C# code, adds that banned IP to the C sharp code, compiles the C code into an executable binary. This C sharp program is actually what adds the IP to the IIS deny list. After the build_deny_list.pl generates and executes the binary, it deletes the original source and executable file.

VVS, Visitor Verification Script for web forms

Displays an ascii art image of a random sequence of letters/digits and asks the visitor to type the sequence in a field provided. If the typed sequence is the same as in the image, the original form script (action) is invoked. Otherwise, the visitor is asked to go back and correct what he/she typed before. VVS requires Perl with the CGI class. It works for any form script written in Perl, independently of whether the script uses CGI or cgi-lib.pl or etc. It also preserves values of arbitrary variables of the environment for use in the original form script.

IIS_ipblock

This script was written to help stop automated brute force attacks against your website. Are you tired of seeing www.yourdomain.com... ...cmd.exe in your log files? This script uses a custom 404 page that logs the IP address of the person making the 404 requests and after so many requests it adds that IP to the IIS servers deny list. There is some HOWTO information with the download...Be sure to read the README.html file! This script works against requests made via browser, wget, raw HTTP...maybe more. I updated this script to use a safe.log. You can add Ip's you dont want to ban in the safe log. IP's you might not want to ban are those used by Googlebot or Slurp (yahoo bot).

Spot Hackers

Find the most common way of hacking and be notified by email/pager around the clock. Most hackers use /tmp to hack linux servers by writing some file in /tmp directory and call it remotely to play around in your server. If you are offering shared-hosting or web hosting services on your server, then you are making this much easier for hackers to find access to your /tmp directory. There are many ways of closing or limiting their access to this directory such as running PHP with suEXEC Support. I assume you already know all of those and you have a very secure /tmp directory. However, often hackers find newer ways of accessing this directory. Therefore, it is necessary to check this directory often to make sure nothing is going on without you knowing it. Following script was written to check /tmp directory or any other directory and notify the admin if any un-authorized file exists. To keep this example simple, we are looking into each file and look for different keywords such as "perl". Keep in mind that this script can only detect files with source, not executables. This is still very useful as most hackers use wget method to write something into this directory. You could setup a cron-job to run this every few minutes and have it email you as soon as it finds something. Script will also create a log file of what it finds.

PerlSpy

Do you have pages that you want to keep visitors off such as login and security pages? Do you want to know as soon as a visitor lands in a particular page because you're just curious? Well, PerlSpy is a script that sends you an email alert the moment someone visits any "marked" page with all the info you need to know about that visitor such as IP, Host DNS, exact time of visit, the referring URL, the browser, OS, ...etc. You can easily "mark" those pages by inserting one line of HTML in them and the script does the rest. PerlSpy is not really a security system, it's not a counter either; it's something in between. Its applications are countless and depend only on your imagination and curiosity. Just don't flood yourself with emails if you're expecting millions of visitors :)

PassGen

PassGen, an easy way to make sure your users choose secure passwords to cut down on password hackers breaking their accounts open! Set comes with 2 scripts, one that allows them to enter data and generates a password based on that data, and one that randomly chooses a secure password and displays it for them. Both scripts use 2 arrays, 1 for letters(of both capital and lower-case letters) and the other for numbers 0 - 9. It iterates through a loop and picks out random numbers and letters and put them together. Given that they are random, it makes it very difficult to be "cracked" by malicious "hackers". It then returns the password and displays the page, generated_password.html in your templates/ subdirectory.

IPLog

You place an SSI tag on your webpage and then whenever the page is loaded a database is updated with that persons IP in it. This is useful for security purposes especially on credit card orders! The database will log the hostname on the page, the IP on the page and time it was requested - obviosuly the page name and path is logged too. There are two modes of operation, administrators can either choose text based databases or MySQL based databases. This allows for the administrator to have a site ideally suited to him which grows with his/her requirements. The "administration" section of the website contains two pages. The first lists all the IPs and the pages (everything stored in the database in other words), and the second is a page which allows deletion of individual records of IPs or all at once. The "listing" page has links to the deletion page.
