So, what is the most important step you can take to keep your WordPress blog secure?
- Keep the software up-to-date
This may sound almost patronizingly obvious, but hold on a second. Every day hackers use unpatched servers or services of one kind or another as the bread and butter of their trade (stealing data, creating Bot networks, selling hacked server access to phishers, etc.).
- Lack of awareness that a patch or update is available or needed
- Lack of urgency regarding maintenance
- Attitude that you are immune to these types of problems, and don’t need to worry about them
Step four would also be to make sure that your operating system is up-to-date. Automating that is almost always possible, but is dependent on what operating system you are using. Google “X automated security update”, where X is your OS.
BTW, I found the jump to 2.5 very smooth and have encountered no problems – Thanks, WordPress!
