Though the WordPress platform is secure enough, it is vulnerable to attacks. The popularity of the platform makes it a favourite target for the hackers. You need to take precautions to make it more secure. Securing the platform is named Hardening. Though those steps do not ensure 100% safety, you can stay protected.
Here are a few tips to make your platform more secure -
1. Update your plug-ins
Keep your core files of WordPress and the plug-ins updated. These updates contain security patches.
In fact, it would be more advisable to restrict the usage of plug ins. Use them only when absolutely necessary.
2. Restrict access to admin area
Provide access to your admin area only to people you trust. More so, give access to only those who are actually needed. Limit the incorrect login attempts.
3. Do not use "admin" password
Name your admin username differently than the usual. Most of the hackers assume that you are using "admin" username. By changing it to some other name, you block majority of hacking attempts.
4. Use stronger passwords
Use a stronger password. Do not use easily guessable ones. Using longer sentences makes it better to secure you from hacking attempts.
5. Keep track of Your dashboard activity
If you have a huge number of members on your dashboard, make it a habit to keep track of what they are doing. Your members may not be doing something wrong to hack your site, but a wrong step by any one of them - even though not deliberate - can make your site vulnerable.
6. Keep your computer clean
An infected system can result in making your WordPress installation prone to hacking attacks. Protect your computer from viruses and malware. Invest in a good anti virus and anti malware solution.
Live....and Let Live!
