#9 Put Procedures in Place to Keep Your Security Current and Address Vulnerabilities That May Arise!
Securing your software and networks isn’t a one-and-done deal. It’s an ongoing process that requires you to keep your guard up. If you use third-party software on your networks, or you include third-party software libraries in your applications, apply updates as they’re issued. If you develop your own software, how will people let you know if they spot a vulnerability, and how will you make things right? FTC cases offer points to consider in thinking through vulnerability management.
Update and patch third-party software.
Outdated software undermines security. The solution is to update it regularly and implement third-party patches. In the TJX Companies case, for example, the FTC alleged that the company didn’t update its anti-virus software, increasing the risk that hackers could exploit known vulnerabilities or overcome the business’s defenses. Depending on the complexity of your network or software, you may need to prioritize patches by severity; nonetheless, having a reasonable process in place to update and patch third party software is an important step to reducing the risk of a compromise.
Heed credible security warnings and move quickly to fix them.
When vulnerabilities come to your attention, listen carefully and then get a move on. In the HTC America case, the FTC charged that the company didn’t have a process for receiving and addressing reports about security vulnerabilities. HTC’s alleged delay in responding to warnings meant that the vulnerabilities found their way onto even more devices across multiple operating system versions. Sometimes, companies receive security alerts, but they get lost in the shuffle. In Fandango, for example, the company relied on its general customer service system to respond to warnings about security risks. According to the complaint, when a researcher contacted the business about a vulnerability, the system incorrectly categorized the report as a password reset request, sent an automated response, and marked the message as “resolved” without flagging it for further review. As a result, Fandango didn’t learn about the vulnerability until FTC staff contacted the company. The lesson for other businesses? Have an effective process in place to receive and address security vulnerability reports. Consider a clearly publicized and effective channel (for example, a dedicated email address like security(@)yourcompany.com) for receiving reports and flagging them for your security staff.
