- How to Change MySQL Storage Engines

MySQL 5.0 and higher offers nine storage engines and more are likely to be added in the future. The most commonly used are MyISAM, InnoDB, and Berkeley DB (BDB). Each storage engine offers special features and advantages. You can even use different formats for each table in your database, though it may be harder to manage a mixed format database. Better is to keep all tables in a database using the same storage engine, but use different engines for different databases.

To determine which storage engines your server supports, run following SHOW ENGINES; statement. The value in the Support column indicates whether an engine can be used. A value of YES, NO, or DEFAULT indicates that an engine is available, not available, or available and currently set as the default storage engine.

- Automatic Web Browser Proxy Configuration using PAC file

The Web Proxy Auto-Discovery Protocol (WPAD) is a method used by clients to locate a URL of a configuration file using DHCP and/or DNS discovery methods. Once detection and download of the configuration file is complete it can be executed to determine the proxy for a specified URL. The WPAD protocol only outlines the mechanism for discovering the location of this file, but the most commonly deployed configuration file format is the Proxy auto-config (PAC) format originally designed by Netscape.

A PAC file is a specialized JavaScript function definition that a browser calls to determine how requests are handled. Clients must specify (in their browser settings) the URL from which the PAC file is loaded. You can store a PAC file on web Server (or on any server in your network) and then provide the URL for this file to your clients.

- Basic MySQL performance tuning using Query Cache

The query cache stores the text of a SELECT statement together with the corresponding result that was sent to the client. If an identical statement is received later, the server retrieves the results from the query cache rather than parsing and executing the statement again. The query cache is shared among sessions, so a result set generated by one client can be sent in response to the same query issued by another client.

The query cache can be useful in an environment where you have tables that do not change very often and for which the server receives many identical queries. This is a typical situation for many Web servers that generate many dynamic pages based on database content.

- Extract individual file(s) from rpm package using rpm2cpio

As the name implies, rpm2cpio takes an RPM package file and converts it to a cpio archive. Because it's written to be used primarily as a filter, there's not much to be specified. rpm2cpio takes only only one argument.

The optional argument is the name of the package file to be converted. If there is no file-name specified on the command line, rpm2cpio will simply read from standard input and convert that to a cpio archive.

- A Complete Guide to Securing a Website - White Paper

To secure a website or a web application, one has to first understand the target application, how it works and the scope behind it.  Ideally, the penetration tester should have some basic knowledge of programming and scripting languages, and also web security.

A website security audit usually consists of two steps.  Most of the time, the first step usually is to launch an automated scan.  Afterwards, depending on the results and the website’s complexity, a manual penetration test follows.  To properly complete both the automated and manual audits, a number of tools are available, to simplify the process and make it efficient from the business point of view.  Automated tools help the user making sure the whole website is properly crawled, and that no input or parameter is left unchecked.  Automated web vulnerability scanners also help in finding a high percentage of the technical vulnerabilities, and give you a very good overview of the website’s structure, and security status.  Thanks to automated scanners, you can have a better overview and understanding of the target website, which eases the manual penetration process.
