Developers have to be alert as there are chances of attacks, URL hacking, etc. To lower the security risks developers must have to take care of some factors. It is not that, you just use 3rd party plug-ins to lower the security risk. To lower the security risk, developers take help of some actions, tools and procedures to overcome some risk factors or at least minimize them. The Content Management Systems are not security hardened as many third party themes and different plug-ins are utilized. Follow the instructions & developers can ease the risk.
Software updates:
The new versions of software load with extended features, bug fixes, security vulnerabilities, etc. WordPress developers must develop each site by keeping Wordpress coding standards in mind. If the site goes down with the update, then it must not be compatible with the upgraded version. Hence, developer must research on each Plug-in and ensure to integrate the plug-ins or themes those are supported by author. If developer is not having enough knowledge about right theme or Plug-in, and include any incompatible stuff, then it may cause many problems in future.
Each users require access control for different features. Provide them access to accomplish their tasks and do their job. Give the access on the basis of user's roles and responsibilities. There must be an administrative account for handling the tasks such as, Wordpress upgrade, add/remove plug-ins & themes. Developers are suggested to include two-factor authentication on WorPress admin. Many times, there are possibilities of brute force attacks on login page wp-admin or wp-login.php. WordPress web developers must try Google Authenticator plug-ins. Don't forget to limit login attempts.
Bugs in Wordpress Plugin:
Any developer can build or expand the plug-ins or functionality to facilitate other developers with ease operations. Sometimes, when developer use badly written or intentionally malicious plug-ins that create many problems.
Passwords:
Don't use small passwords. Experts suggest to add the long pass-phrases in the passwords. For different logins, use varied pass-phrases to decrease the chances of hacking. Another best option is, you can optimize the tool like LastPass, which stores your password secretly. The tool does heavy lifting & changes a password completely that even you don't know. This reduces possibilities of hacking completely. The Wordpress web development company builds many websites and in general, the companies use same combination of username & password to manage multiple sites. This is a big security game that all development companies must take care of. After the deployment also, this user account will be active. Hence, if any unauthorised person or seasonal hacker comes to know your password setting pattern or password, it becomes easy to interrupt the site.
Sometimes, WorPress developers include some plug-ins for testing purpose & forget to remove them at the end. When the sites are deployed, then it is necessary to remove disabled themes/plug-ins. In the shared servers, root account owners upload multiple sites. Attackers are always in search of the site weaknesses & infect the weak places. So, if one site on server is infected, then others may too. Hence, don't allow dummy WordPress instances to be there in site after deployment.
A quick close:
There are many security vectors in CMS. But, as the WordPress is most popular CMS and easy to implement, we can't stop using it. At some cost, we can minimize risk factors. Keep the updated version of technology. Have the long passwords those can not be guessed easily. Only integrate solid plug-ins without any vulnerability.
