It’s a scary scenario that every business fears; a successful attack on your web site that results in stolen information or embarrassing defacement.
From huge corporations, to mom-and-pop online shops, data security is (or should be) a keystone consideration. As we’ve written about before, no one is immune to attack – not even local businesses with small online footprints. I, personally, have worked with many clients whom you would not think would be targeted by hackers, and they end up being the victims of reasonably intricate and damaging attacks that cost many thousands of dollars to mitigate.
Because no set of security controls or solutions can make you truly safe from exploitation, it is important to have a plan in place in case you do get hacked. Having a documented plan ready BEFORE an attack occurs allows you to be calm and rational with your response. Below are some basic steps you should consider in an incident response plan and/or follow in case a breach occurs.
1) Stay calm.
An attack, especially one in progress, naturally causes panic. While understandable, these feelings will only cause you to make mistakes in handling the breach. Stay calm and stick to your plan.
2) DO NOT unplug the system.
Unplugging the affected system, deleting malicious files, or restoring to a backup are all panic-driven responses to a security incident. When you take measures such as these, you potentially destroy key evidence in determining what, if anything, was taken, how it was taken, and when. Leave the system in place and call an expert as soon as possible.
3) Call an expert.
There are many companies that specialize in post-breach analysis, and it is important to contact these folks right away. They can help determine how the breach occurred, what was taken, and when. They can also help implement controls and improve security so that the same attack does not happen again. If you’ve been hacked, this is the most important step to take.
4) Keep a record.
For possible eventual legal action and to simply keep track of system changes, always keep a record of what has happened to the infected system – who has touched it, when, etc.
5) Determine the scope of the attack, stop the bleeding, and figure out what was taken.
The expert you phoned in will analyze the affected system and follow the steps above. Once the scope is understood, the system will be taken offline and the security hole that caused the problem will be discovered and closed. After that, the information that was compromised will be reviewed. This step will help determine how to proceed next.
6) Figure out who to tell.
Once you’ve determined what kind of information was compromised, it is very important to communicate that to the right people. If it was internal documents, you probably don’t need to make that public. If it was usernames and passwords, you must let your users know.
7) Have a security assessment performed and improve security controls.
Have your expert analyze the rest of your infrastructure and web applications for security holes that could be a problem in the future. After this occurs, the expert can recommend tools that will vastly improve your security layering.
Of course, many of these tasks can be performed proactively to greatly reduce the likelihood of ever needing this process. Contact an expert now and have them analyze your systems for security vulnerabilities.
