Brute force attacks, where hackers systematically guess usernames and passwords in an attempt to gain access, remain one of the top security threats facing WordPress websites today. As the world‘s most popular CMS, with a 36% global market share, WordPress remains an attractive target for automated attacks seeking administrator access.
In this comprehensive 2800+ word guide, we will explore multiple methods and best practices site owners can employ to protect against brute force attacks on WordPress, some easy to set up, others more advanced and layered for maximum security.
Hiding the WordPress Login Area
One of the easiest first steps to securing WordPress is to obscure where the login page resides from hackers and bots scanning your site for vulnerabilities. By default WordPress installations have a login URL at:
- /wp-login.php
- /login
- /wp-admin
- /admin
Bad actors know to probe these locations when scanning WordPress sites. Plugins like WPS Hide Login and iThemes Security can change the login URL to anything you want, hiding it from unwanted attention. They can also disable directory listings and return 404 errors if default admin locations are accessed.
This simple step instantly makes your site more secure from automated tools looking exclusively for wp-login.php pages. It also protects against human hackers trying common paths first before turning to credential stuffing or brute force attacks.
Major security plugins like Wordfence and Sucuri offer similar login obscuring features along with added site firewalls, malware detection and other key protections.
Additional Plugins for Login Security
While the plugins mentioned above are potent options, there are some alternative and lesser known tools for hiding and protecting WordPress login pages:
-
WP Secure Login: With a lightweight 3KB footprint, Secure Login rotates and flushes rewrite rules to guard login endpoints.
-
Rename WP Login: As implied this plugin simply renames wp-login.php and pulls it out of public visibility for masking.
-
Better WP Security: A long-trusted favorite of WordPress admins, Better WP Security hardens sites in various ways including disguising admin pages.
-
Shield Security: Offering an extensive paid security plugin, Shield has features to obscure visible paths to wp-login pages and administrator accounts.
For high value enterprise sites, paid premium options like Sucuri (~$200/year) and Defiant‘s WPScan Pro ($99/year) identify exposed users through login testing and help eliminate this threat vector. The investment here depends on your site‘s security priorities and risk appetite.
Two-Factor Authentication Drastically Improves Security
Another easy “quick win” in securing WordPress is enabling two-factor authentication (2FA). 2FA requires users enter a one time passcode during the login process from a separate mechanism along with their username and password.
This protects against credential stuffing attacks (using valid passwords from breaches on other sites) and blocks login attempts where an account password is correctly guessed. It provides a strong secondary defense layer.
WordPress plugins like Two-Factor and Google Authenticator make enabling 2FA simple. Users can access passcodes from a smartphone app or have backup one-time use codes sent via email if their device is unavailable. Despite a few extra steps, the improvement in login security is enormous.
For example, research from Duo Security analyzed over one million user accounts and found adopting 2FA reduced risk of account compromise by 63%. For administrators, using hardware tokens like Yubikey provide high assurance access.
| Attack Type | Risk Reduction With 2FA |
|---|---|
| Phishing | 76% |
| Keylogging | 61% |
| Brute Force | 96% |
With such a substantial decrease in susceptibility across common attack types by adding 2FA, there is almost no reason not to implement it. The number of quality free and paid plugins available gives site owners flexibility to choose what works best for their needs.
A Layered Collection of Plugins Creates Depth
Rather than relying on just one magic plugin for total site security, administrators gain protection through using a collection of hardening and monitoring solutions. Attackers adapt to plugin defenses over time or seek to exploit logical issues between features.
Defending against this requires depth through layered controls, not a single point of failure. For example, Wordfence not only obscures admin pages from access and provides a firewall, but it offers login rate limiting along with country and IP blocking to halt suspicious activity early in the attack chain.
Login Lockdown takes a different approach, requiring added proof through password access tokens sent to admin emails before unlocking blocked accounts. This delays rapid brute forcing significantly. Limit Login Attempts auto bans users after a defined number of incorrect passwords tries over a period.
Pairing these types of intelligent blocking, delaying and monitoring plugins with disguised login areas, 2FA codes and active threat detection provides protection from multiple angles. Ransomware focused tools like Shield Security tackleinjection risks as well through isolation. For under $100/year, the features bring enterprise level security within reach of small business.
Understanding your site‘s weak points and highest risks allows logically choosing complementary plugins to address those concerns. Educated, layered security removes single solutions as targets.
Cloud-Based Security for Enterprise Brute Force Protection
For organization-level brute force protection, implementing a cloud-based security solution can provide robust defense. Companies like Sucuri and CloudFlare operate global networks that filter all traffic to your site, allowing only legitimate visitors through while blocking malicious requests aimed at user credential attacks and other threats.
Cloud proxy filtering mitigates security events before they ever reach your WordPress server, eliminating strain on your host resources. Integrations facilitate features like malware detection, firewall rules, DDoS prevention, bot mitigation and WAF policies to take programmed actions in response to varying incidents.
These services require a monthly or annual fee but provide incredible value compared to the business impact of a major security breach. CloudFlare starts at $20 per month for basic coverage while Sucuri offers complete site hardening from $16 per month. For ecommerce sites and those storing valuable data, the expense brings peace of mind.
The economies of scale by diversifying risk across client bases and using enormous processing power to detect emerging attack campaigns contains damage for everyone. Cloud solutions continue securing sites even during elevated threat levels from cybercriminal groups.
Hardening Your Web Servers and Infrastructure
It’s important to properly configure supporting infrastructure underpinning WordPress sites, not only rely on WordPress application hardening. Many brute force attacks originate from server and network vulnerabilities outside CMS code itself.
Ops teams need to track patches and updates for web and database servers, use SSH key access instead of direct root/sudo passwords, close unused ports, limit plugins and enforce complex admin passwords exceeding 12 characters. Failing to apply security best practices leaves preventable gaps.
Tools like Fail2Ban take server protections further by monitoring logs for suspicious activity and then directly blocking nefarious IP addresses via firewall iptables rules. This occurs at the Linux OS level, preventing the attack traffic from ever interacting with WordPress PHP processes.
Web application firewalls (WAFs) like ModSecurity filter all HTTP requests as they come in, having deep context on application logic to identify malicious payloads destined for exploits. They function on web servers for finding low level issues before PHP code execution.
Hardening choices align to your risk tolerance. However, correctly configuring servers supporting WordPress closes an attack avenue on infrastructure many sites neglect. Choosing options fitting your environment provides defense in depth.
Emphasizing Security Awareness and Training
With the human factor being one of the consistently weakest links across all organizations, providing WordPress security awareness education and cybersecurity basics training to content editors, administrators and developers allows them to be part of prevention.
Covering topics like:
- Proper password creation
- Password manager usage
- Identifying phishing attempts
- Monitoring account activity
- Security incident reporting
makes it exponentially harder for social engineering around login access to succeed. Users wanting to protect systems but lacking knowledge often unintentionally make themselves easier to exploit. Bridging these gaps raises the overall posture.
For example, academic research found employees undergoing an hour long cybersecurity awareness course were far less likely to then fall for phishing attacks – dropping from 15.3% to just 1.2%. The difference shows information helps negate human blindspots.
Empowering your users with baseline knowledge pays dividends in aligning human behavior with technical controls. It also surfaces issues faster for investigation. Making education an ongoing activity through lunch talks, newsletter tips or games keeps material fresh while reinforcing previous lessons.
Conclusion: A Layered Approach for Robust Protection
Shielding against brute force amplification and credential stuffing attacks targeting WordPress login pages requires applying security best practices from different vantage points in layers. Employing plugins, two-factor authentication, infrastructure hardening, cloud filtering, advanced monitoring and user training in tandem provides defense in depth with fail overs.
Just as crucial as implementing login obscuring and threat detection is configuring supportive servers and databases properly, filtering traffic via security providers and educating editors on their vital role. No single product or action secures sites.
With hacking tools advancing, protection requires matching their innovation with your own – evolving defenses across:
- Obscuring/Disabling Default Admin Paths making site mapping harder
- Employing Centralized Security Plugins to block and delay
- Enforcing Two-Factor Authentication increasing identity assurance
- Configuring Server Access Restrictions to prevent exploits
- Cloud-Based Security Filtering to catch high-level threats
- Educating Users on Passwords and Activity to raise awareness
This robust set of internal controls, boundary restrictions and cloud supported defenses substantially reduces risk of compromise due to automated credential attacks or unauthorized login changes.
While no site is completely impenetrable, demonstrating security proficiency through advanced WordPress hardening and infrastructure support noticeably decreases business risk both from data loss and reputation damage. Prioritizing protection initiatives improves outcomes when incidents inevitably occur.
