The database might be queried for relatively static information, such as books written by Arthur Conan Doyle, or quickly changing data, such as recent comments on a popular discussion thread.

Databases drive dynamic content, store product catalogs, track orders, maintain user profiles, and perform many other functions behind the scenes. SQL injection vulnerabilities enable an attacker to manipulate the commands passing between the web application and its database. To understand why, let’s first examine the hack in detail. By now, it’s almost inexcusable that sites fall victim to this hack. It means that immunity to SQL injection can be designed into a web application with countermeasures far less complicated than dealing with HTML injection.

This doesn’t mean an Orwellian excision from the history of web security. In spite of the alarming introduction, this chapter shouldn’t exist. Mike Shema, in Hacking Web Apps, 2012 Understanding SQL Injection Thus, the previously mentioned machine could be set with: Note that activation tuples are in hexadecimal, are case insensitive, and don’t require you to start the numbers with Ox. The command activation-key sets the key to the new value. Updating the activation key in version 7.0 of the PIX OS couldn’t be simpler. The flash activation key is the SAME as the running key. This platform has an Unrestricted (UR) license. Alternately, the show activation-key command provides this printout: The activation key enables feature-specific information such as interfaces, HA, and type of encryption.įor more information about the activation key, use the show version command, which provides code version information, hardware information, and activation key information.

The serial number is based on the flash thus, if you replace the flash, you have to replace the activation key. The activation key is computed by Cisco, depending on what you have ordered and your serial number, which is different for each piece of PIX hardware. The activation key allows you to upgrade features without acquiring new software, although the process is similar. Although the hardware is common to all platforms (except certain licenses that can ship with additional memory or hardware accelerators) and the software is common, features differ depending on the activation key. The PIX uses software licensing to enable or disable features within the PIX OS. In Firewall Policies and VPN Configurations, 2006 Software Licensing and Upgrades
