that case, it might be a better idea to forgo installing parental controls. Methods to bypass parental controls Several methods of bypassing parental controls can be used. If the filtering software is located locally within the computer, all Internet software can be easily bypassed by booting up the computer in question from alternative media, with an alternative operating system or (on Windows) in Safe Mode. However, if the computer's BIOS is configured to disallow booting from removable media, and if changes to the BIOS are prohibited without proper authentication, then booting into an alternative operating system is not available without circumventing BIOS security by partially disassembling the computer and resetting BIOS configuration using a button or jumper, or removing and replacing the internal button cell battery. Using external proxy servers or other servers. The user sends requests to the external server which retrieves content on the user's behalf. Filtering software may then never be able to know which URLs the user is accessing, as all communications are with the one external server and filtering software never sees any communications with the web servers from which content really originated. To counter this, filtering software may also block access to popular proxies. Additionally, filtering systems which only permit access to a set of allowed URLs (whitelisting) will not permit access anything outside this list, including proxy servers. Resetting passwords using exploits Modifying the software's files Brute-force attacks on software passwords 'Incognito/InPrivate' modes with the 'image' tab: Users, parental control software, and parental control routers may use 'safe search' (SafeSearch) to enforce filtering at most major search engines. However, in most browsers a user may select 'Incognito' or 'InPrivate' browsing, enter search terms for content, and select the 'image' tab to effectively bypass 'safe search' and many parental control filters. See below for router based considerations and solutions. Filtering that occurs outside of the individuals computer (such as at the router) cannot be bypassed using the above methods (except for 'Incognito/InPrivate' modes). However, The major search engines cache and serve content on their own servers. As a result, domain filters such as many third party DNS servers, also fail to filter the 'Incognito/InPrivate' with 'image' tab. Most commercially available routers with parental controls do not enforce safe search at the router, and therefore do not filter the 'Incognito/InPrivate' with 'image' tab.
