Managing data breaches
All businesses with an online presence face a range of cyber risks. Prominent among them are data breaches, which constitute a class of vulnerability that the public is particularly concerned about, especially in light of recent high-profile data breaches like that which affected Facebook in September 2018. There’s no way to eliminate cyber risks like data breaches but there’re a variety of measures that can help businesses manage and mitigate risks.
Reducing the risk
As with so many other risks, the best way to manage cyber risks like data breaches is to reduce the risk and exposure as much as possible. Reducing the risk protects a business and its customers and clients from having their data compromised while reducing the exposure protects a business from the consequences of data breaches
Reducing exposure is best accomplished by purchasing cyber liability insurance. Reducing the risk is best accomplished by implementing the security measures that best suit the business and the type of data being held. Unfortunately, there isn’t a global standard or a solution that suits all organisations.
Regardless of which security measures are chosen, it’s vital that security products and services be continuously monitored and kept up to date. Businesses must also take steps to ensure basic cyber safety practices are implemented. This includes measures like good password practices and employing data encryption where relevant. This won’t create a foolproof system that eliminates the risk of a data breach occurring but it will significantly reduce the risk.
Responding to a data breach
In addition to implementing practices and procedures that prevent data breaches, a good data breach risk management strategy will include guidelines that should be followed in the event a breach does occur. Such guidelines should specify whether IT, PR, legal etc. professionals need to be engaged and should also cover protocols for:
-
Containing a breach and limiting further damage
including protocols for shutting down and preventing further access to a system that has been breached
-
Assessing the risks associated with and impacts of a breach
including the impacts on the business, such as whether compromised data will affect other business processes or relationships with third parties, and the impacts on the business’s customers, such as the number of people affected and the nature of the data that was compromised
-
Reporting a breach
who needs to be notified, when and how they should be notified and what information they need to be given
-
Rectifying a breach
including procedures for attempting to recover lost data and restarting compromised systems
-
Assessing the effectiveness of the response and preventing future breaches
including protocols for: determining whether criminal activity, human error or inadequate procedures contributed to the breach; evaluating any operational, policy, resource, employee or management issues that arose during the response to a breach; and modifying any procedures or behaviours that contributed to the breach
Summary
Managing cyber risks like data breaches requires an integrated approach designed to:
- prevent an attack
- limit the exposure
- respond to an incident in the event prevention fails
