Data Breach? Privilege misuse? Stolen money? Do you really think that your web application has never been breached? Here are ways to find out.
Not all data breaches make it to the newspaper headlines. Some remain dormant and hidden for years. Hackers use them as backdoors to collect and circulate information or to look for other loopholes. The questions here are- How would you know if an application has been hacked?
When application log messages are checked and monitored properly, they tell a lot about access, location, and time. Most companies are either too busy to scan through these logs or just do not care. The following are some of the signs that can help find out if there is something wrong with the application.
The easiest way to find and report application breach is to monitor what it is supposed to do. Comparatively slower request processing, increased time in loading pages, a sudden surge in traffic or number of orders are some of the red flags every website owner should be aware of. While such indicators do not necessarily point towards a hacking incidence, it is never a bad idea to look at what’s wrong rather than waiting for the obvious signs.
Process monitoring for web servers should be a critical task for administrators. Much like with our computers, processes tell us whether unusual tasks are being created to carry on specific jobs. More often than not, it’ll unveil hacking attempts at a very early stage.
If some pages of your website are redirected, defaced, or hosting any kind of worm/malware, there are chances that popular browsers and search engines will pop warning messages. Google Safe Browsing is one of the tools that can help bring out such issues on the website.
Timestamps on web application files help you find out if it has been edited or deleted recently. In most hacking cases, security experts find that files that are untouched for years suddenly have a new edit date. If developers and website administrators look for such changes and then compare the newer and earlier version, it reveals application vulnerability or malware on the server.
Web application firewall (WAF) is one of the better ways to gain attack insights and ensure that hackers cannot use these methods every again. IP reputation check, incoming bot traffic, sudden high volumes are some of the key red flags used by WAF to detect hacking incidences.
