Unfortunately, there seems to be a misconception that once a cyberattack occurs, there is not much that can be done to fight back against the attackers. This couldn’t be further from the truth. 

After a data breach or cyberattack descends on your organization, there are thankfully several active defense steps that you can take to minimize the amount of havoc caused by cybercriminals. These steps are focused on detecting attacks as early as possible, gathering the information that is necessary to understand the full scope of the attack, and preventing similar attacks from happening in the future.

Step 1: Control the amount of damage.– As soon as a hack or breach is detected, separate and quarantine any infected systems to contain the breached files and keep the attack isolated. This will prevent the attacker from gaining access to any other information and will limit the amount of damage. Additionally, your data analyst or cybersecurity professionals will also have time to safely collect information about the attack so that they can figure out what they are after to help better protect against future threats. 

Step 2: Conduct a forensic analysis.– After an attack is detected, your team should perform a forensic analysis to understand what happened. Information such as where the attack originated, how it was executed, and how long it took for the attack to be found should be identified during this analysis. After these questions are answered, an effort should be made to understand what the goals were and what can be done to prevent another similar hack from happening again.

Step 3: Search for similar attacks and respond with countermeasures.– Use the identifying information to search for any attacks of a similar nature that could be occurring at the same time. The identifying information of this attack can be used to help your team methodically search through your IT landscape to find attacks that may not have been discovered yet. Then, to prevent issues in the future, take this a step further by creating a series of automated or manual counter responses that are triggered by these same characteristics. This will save time should an attack of this nature occur again.

Step 4:  Share your newfound information with the intelligence community.– Share the information about the hack not only with your own employees, but also with the intelligence community as a whole. This could prevent other organizations from suffering the same breach as your company while also inviting them to share information with their own detected attacks with you.

Step 5: Train your employees.– Even if you spend millions of dollars on studying cyberattacks and improving security infrastructure, all it really takes is for one employee to click on the wrong link to compromise your critical data. Instead, remember that the best defense is a good offense and protect your information with CyberSAFE™cybersecurity training.
