WordPress security guide

This article of WordPress aims at beginner’s guide for new webmasters especially those who deal with WordPress. It runs with highly successful and popular PHP scripts. Most important considerations of WordPress are that it runs with open source software and supported by a wide range of enthusiastic who always indulge in finding out a newer way to secure WordPress. Still, it has many security issues as there are some people who take advantage of the open source movement and put forward newer ways to hack WordPress sites. This article helps users to find out such critical security issues and help webmasters to wipe out such problems completely.

This article showcases how to prevent common types of attacks on WordPress by sanitizing input and output. It helps you to increase security of files. Databases and sessions of WordPress Administration login so that users will not be feeling helpless and puzzled while working with hosting of WordPress. Webmasters must learn to validate entire PHP strings, numbers and dates so that there would be the way sign of day light saving times.

Most newer webmasters must be familiar with regular expression of PHP and different security extensions through which WordPress works. PHP is famous because it provides wide arrays of procedures to completely integrates the entire range of outside applications into host of WordPress sites. WordPress runs with PHP so for this in order to master functioning of WordPress one should learn in detail about PHP and its strings and functions.

Remember once insecure PHP application could put forward huge degree of external pressure on the host server and its different input standards in order to make server down due to use of extreme resources. These vulnerabilities and different functioning of websites could lead to significant corruption of data due to extreme pressure on its CPU and makes it more prone to end of the entire database which you should not be aiming when you start any website.

As a web developer and web master you should always be in the midst of the difficult path that at some point at times one could enter into different codes of your application and could stop the entire application from running smoothly. At any point of time someone would find fault in your coding standards and slowly entire bit of coding would become a bunch of malicious codes. These are practical realities one should always be live it with.

Most common forms of malicious attack are known as ‘SQL injection attack’ which is done through MY SQL database of yours article repository and then put forward attacks on website single handedly without waiting for response. The injection query is embedded inside SQL query and when such query is initiated the injection code runs along with such query to make entire database corruption and entire website unable to function. Most of times developers by mistake rest some special character of symbols inside PHP or MY SQL database and for this entire code mechanisms needs to be sanitized and such codes needs to be removed at first hand in order to provide a safer place for developers to work it out.

Most of times, in order to make WordPress website nice and good many developers install third party themes and most of these are free to use but in this world nothing is as such free and one needs to understand that developers of theme make it free only because when you install such theme on your website it uses hosting space of yours website and this put extra pressure on hosts. Through the process of hot liking of articles, most of times, hosting space and server is used by known bots and this makes entire hosting to use additional central processing units and that creates much difficult space for webmasters as most of times website stays with resource full due to highly use of resources of central processing units.

Within PHP coding of WordPress one could go for adding ‘add slashes’ function to escape from such by mistake characters which could have provided heavier impact on web performances. If you are good at handling MY SQL functionalities, then you could introduce ‘real_escape_string’ method in order to sanitize database. WordPress works in both ways, it could act as website as well as a brilliant content management system.

Most times, while performing commenting hackers put forward some malicious characters which could easily be stripped for HTML and PHP tags through ‘strip_tags’ functions. WordPress runs with its database just like a content management system and for this it is important to secure the entire database. Most of times many website offers ‘code guard’ as database back up system and it is important to remember that, whatever be the situation and environment at some point of times due to potential outrage of server one could find that entire database could have been in the stage of corrupt and for this it is important to stay nearer to find and secure entire database for convenience of users.

One should remember any files that are located inside server document root, can easily be found and in use by remote users. So do not store sensitive files inside document root of WordPress. One should not use HTTP documents processing too much for sensitive areas which is meant exclusively for the web administrator. One should always provide call to files in terms of ‘require’ and ‘include’ functions so that third party applications and users could not import such files by using remote procedure call functions.

Another way to stop such trespassing into document root by third party applications and visitors to introduce ‘Nix development system’ so that every file must go through specific paths through particular web server processes. Most of times WordPress runs with database MY SQL and it is a relational database management system and for this in order to secure database one must go through such stricter database principle so that with these simple steps MY SQL database becomes secure and stops all signs of attacks before they are properly executed.

WordPress provides access to different users in terms of subscriber and moderator. One should grant users just to the level of access that they need in actual. It deals with privilege levels of users and these could be restricted and marginalized through the process of ‘GRANT’ and ‘REVOKE’ commands. It is important to grant such users to the level of the database which you permit users to use that database, so when attackers attack through such users, the extent of the level of damage could be minimal.

Use secure passwords to stop all signs of attacks as most of these attacks come from a weak password and in, this way root directory could be properly configured. Thirdly, the single most important functions to stop attackers from intruding into the system are to do away with remote access. Only allow local access to remote server and this would only allow an administrator to access website and its host. If you are comfortable with MY SQl functions then you can use ‘—strip-networking’ option at start up server times to remove all signs of remote logging and controlling of database.

WordPress is best known for its cache management system and this is done with securing of sessions and all these remain in cache so that website runs most times even during partial outrage of server. Hackers take advantage of this and used to hijack a session in order to increase high central processing unit and make it almost down for longer hours. By completely hijacking users session and creating recreating such sessions most times downtime of website increases considerably.

Create ‘User-Agent’ PHP function within theme function files of WordPress so that at starting of session remote agent such as browser agent is being recognized, with http user agent and that echo of remote user agent is being echoed, with session id and informs server that session has now started. Before applying ‘User-Agent’ function it is important to login to WordPress back end of administration and then a user profile and then remove all instances of logging so that there would not be any confusion regarding the way different logging into the system goes on.

Now, all such instances are recorded within function files and when administrator logs into, it starts another session and then verify remote agent and its http user agent and then allow the remote user to login and most of times only one user such as administrator is allowed into it. If session is verified and proves to be correct then codes are processed and the dashboard open from there. This method is simple but not full proof, when entire hosting sessions are being hijacked then it is difficult to rectify this.

Many web masters prefer to go for, converting redirecting functions of WordPress administration in order to provide stricter control of the back end of WordPress to remove all signs of bots and hackers from entering into sight. This proves to be difficult to implement and many a time, real administrators also faces stiffer problems as well as stricter time and again trying out logging into the system in order enter into the dashboard of WordPress.

Many a time, at various instances MY SQL database does consist of some empty records, which run regularly with database systems. It is important to do away such empty records in order to create one of stricter access of the database. Most of programmers do reach to find out such empty records and then fill out such records and manipulated them and succeed in entering into the database completely.

Delete all non-empty and non-zero values from database. Initiate ‘empty’ function inside PHP to find out such traces inside WordPress content directory and then reach to live theme function from there. Some web hosting do introduce the concept of Gzipping of website through add on or allowing modifications through .httaccess files and this removes all traces of empty spaces inside PHP scripts when such codes are executed inside web browser and converted into HTML to turn into visible website from there. Here the variable is simple compared with leading and trailing spaces of existing space there.

The ‘trim’ function of PHP runs deep into website and then it squeezes such spaces in order to secure WordPress and execute nicely within deeper security environment. Always try to use PHO scripts instead of Javascript or HTML codes as most of times, when visitor uses ad blocker as most users use it, it simply removes such traces of script as PHP validate within client side and it depends upon modifications of server in order to perform excellently and for this when user stops these scripts such flow of scripts stops from there completely.
