Online attackers are increasingly targeting
websites to make a statement, send spam or flood someone else’s network.
Protecting your online brand requires vigilance.
When a big website like Lenovo’s gets hacked,
it’s news. But most such attacks take place under the radar, at smaller
sites lacking the skills or time to protect themselves. Take the
legions of Wordpress-based sites, which got a rude awakening last year
when many thousands of them were hacked.
Don’t be one of those sites. Even if you don’t use Wordpress, you can
learn important lessons from what those poor blighters have been
through.
The un-magic bullet: site maintenance
Quickly spinning up a Wordpress site on a hosted server is simpler than
ever, but users need to understand that the sites require regular
management. Cybercriminals and hackers are continuously looking for
sites whose administrators use easy-to-guess passwords, inadvertently
misconfigure the site, or fail to apply the latest patch.
Earlier this year, for example, security firm Zscaler found that compromised WordPress Web sites were forwarding visitors’ login credentials
to an attacker-controlled site. Last year, in one of the worst cases of
serial compromise, a malicious program, known as SoakSoak, infected more than 100,000 Wordpress sites
using a vulnerability in a popular plugin. “The beautiful thing about
these applications is that they are easy to use and make it easy to get a
website up online,” Tony Perez, CEO of Sucuri, says. “But it’s a
double-edged sword—we cannot depend on the users to be able to manage
the sites securely.”
Security experts don't blame the content management systems, which
typically take security seriously. But Wordpress sites account for 24
percent of all Web sites, and Joomla and Drupal account for another 5
percent, according to Web technology firm W3Techs. The software is under
intense attacker scrutiny. Attackers have historically tried
brute-force password guessing as a first assault on content management
systems, followed by quickly attempting to take advantage of any
just-published vulnerabilities.
Passwords are an easy problem
for users to solve, but keeping up with a steady stream of
vulnerabilities and patches requires diligence, says Mark Maunder, CEO
of Wordpress security firm Wordfence. These three best practices will
help you fend off attackers.
1. Update as soon as possible
Anyone managing their own site should either use a hosting service that
manages the core content management system (CMS) updates or create a
process to keep up with information on vulnerabilities that could impact
their installation.
Be warned, it’s a tough job. Subscribing to any vulnerability feeds for
their software and plugins is a necessity to quickly patch
vulnerabilities in either the CMS or its plugins. Yet, it’s easy to be
inundated, says Sucuri’s Perez.
“It is almost impossible for developers to keep up with
vulnerabilities,” he says. “They are trying to run their site, and
trying to keep track of all the patches and applying them is difficult.”
Web-security services like Sucuri, Cloudflare and Incapsula can buy
administrators more time to patch their sites, by blocking known
attacks.
2. Don’t forget your plugins and themes
While keeping the main content management system up-to-date is
challenging, patching every plugin can be a more onerous burden, as
attackers have increasingly targeted vulnerabilities in plugins and
themes to compromise Web sites.
“In general, attackers are trying to own as many WordPress sites as
possible using as many zero days or recently-disclosed vulnerabilities,
and then using that site for other attacks,” says Wordfence’s Maunder.
A variety of Wordpress plugins provide security. Wordfence, BulletProof
Security and iThemes Security perform a variety of security-related
tasks, from scanning Web sites for compromises to setting the security
controls of a WordPress site to harden the software against the most
common attacks.
3. Regularly maintain your Web site
Having a hosted Web site is a responsibility and requires frequent
maintenance. Administrators should back up the site, and make sure the
backup is copied off the Web server—many inexperienced administrators
overlook that step, says Maunder.
If you don’t have time to do this, go with a fully managed site.
Wordpress.com has a wide variety of templates and more flexibility than
ever before. For other content management systems, such as Joomla and
Drupal, a hosted service provider can manage the CMS on that server and
help keep your Web site patched.
