Public companies may need to look more closely at their exposure to cyber attacks after new guidelines were released last week by the U.S. Securities and Exchange Commission.
The guidelines, from the SEC's division of corporation finance, aim to help companies determine when they need to disclose cyber attacks or the amount of risk they pose to a business.
In general, public companies in the U.S. are required to disclose incidents that could have a material impact on their business. While the current regulations don't specifically mention cyber attacks, the new guidelines say they need to be reported in some cases.
Companies should disclose the risk of cyber incidents "if these issues are among the most significant factors that make an investment in the company speculative or risky," say the guidelines, issued late Thursday
To determine that, companies need to look at factors such as how likely it is they will be targeted by an attack and what the cost of an attack might be, in terms of disruption to operations or loss of sensitive data.
They may also be required to give details about hacking incidents that took place in the past.
"For example, if a registrant experienced a material cyber attack in which malware was embedded in its systems and customer data was compromised, it likely would not be sufficient for the registrant to disclose that there is a risk that such an attack may occur." Instead, they would probably be required to reveal specifics of the incident, the SEC said.
The guidelines come in a year that has seen numerous high-profile hacking incidents, including a massive attack on Sony that forced it to take its PlayStation Network offline for more than a month.
The risk of cyber attacks has always been a potential disclosure issue, but the SEC guidance "really highlights the issue and brings it to the fore," according to David Navetta, a founding partner of Information Law Group, which provides legal services related to IT matters.
Even so, he wrote in a company blog post, "materiality is still going to be a big issue, and not every breach will need to be reported as many/most will not likely involve the potential for a material impact to a company."
One interpretation of the guidelines is that "companies internally are going to have to more carefully forecast and estimate the impact of cyber incidents and the consequences of failing to implement adequate security," Navetta wrote.
"This analysis will go well beyond privacy-related security issues where most companies have focused (due to various privacy laws and regulator activity), and implicate key operational issues impacted by security breaches," he said.
