Cyber Risks – Managing End-of-Life Software

As a small business, it is often easier, more expedient to continue working with EOL software because its easy, we know it, we understand it; and/or all too often replacing it is a capital or recurring monthly expense we do not want to incur.  This article discusses the risks of continuing to use EOL software and discusses best practices for organizations to mitigate this risk.

Risks of EOL Software‍

Known but unmitigated vulnerabilities are among the highest cybersecurity risks. For instance, the Canadian Centre for Cyber Security became aware of several compromised computer networks in Canada in 2020. In many of these cases, compromises occurred because servers were running software with known vulnerabilities. 

Organizations may be hesitant to transition away from EOL software for a number of reasons, such as:

• New software lacks necessary features
• Limited resources
• Migration challenges
• Lack of accountability for replacing software

This is especially true when EOL software is still functioning. However, continuing to use EOL software also comes with a myriad of risks, such as:

• Heightened cybersecurity risk—Without security fixes from the developer, EOL software becomes riddled with security hazards that hackers are often quick to exploit.
• Software incompatibility—New applications will be designed for current software, meaning EOL software is often unable to accommodate newer apps. Organizations that continue to use EOL software will likely have to hold onto legacy systems and applications even when newer and better versions become available. This poses additional risks, as out-of-date applications may soon reach EOL as well.
• Inability to stay in compliance with regulations—Regulations requiring companies to meet minimum data security standards must be adhered to. As a result, organizations that use EOL software and fail to adequately protect sensitive customer data may be deemed noncompliant. Consequences may include fines or company shutdowns.
• High operating costs—Attempting to maintain, patch and bug-fix EOL software without developer assistance can be costly. In some cases, the cost of trying to patch EOL software may exceed that of replacing old software to begin with.
• Poor performance and reliability issues—Organizations running out-of-date software may be more likely to experience software or system breakdowns. Such failures can result in costly downtime and additional operating costs.

As such, proactive management is a necessary step to prevent unwelcome surprises and keep your organization secure.

Managing EOL Software‍

Although many organizations are prepared for the initial lifecycle stages that come with introducing new products, few businesses are prepared for what will happen when it inevitably comes time for these software components to be phased out. Consider the following tips for EOL management:

• Create a lifecycle management plan. Implement effective planning for EOL management to reduce cybersecurity vulnerabilities, lessen the risk of downtime and remain compliant with regulations. Your lifecycle management plan should include all aspects of a product lifecycle, beginning with the introduction of new software to EOL and extending to plans for phasing out unsupported software.
• Understand device history. Use device management software that will automatically capture important information about devices when they connect with the network (e.g., model number, IP address and certificate status). Such software can provide your organization with a highly detailed network overview and will enable your organization to push software and firmware updates, certifications and other necessary upgrades to thousands of computers on your network simultaneously.
• Monitor EOL status. Stay current on EOL notifications regarding all critical components of your organization. Most major suppliers have lifecycles for products and product components, including EOL dates. Best practices suggest reviewing the EOL dates of new software before selecting it for current use. Planning for EOL will help your organization avoid any surprises about when devices or software will no longer be supported, enabling your organization to plan and budget for the replacements.
• Maintain consistent cybersecurity practices. Ensure compliance with cybersecurity best practices. Some areas to consider include policies surrounding multi-factor authentication, password strength, compliance with regulations and how frequently risk levels are assessed.
• Communicate early and clearly. Inform customers of all upcoming EOL issues and your plans for addressing them. Being communicative and transparent can help your organization improve customer loyalty and trust during EOL transitions.

It’s evident that EOL software exposes organizations to heightened levels of risk. Additionally, many insurers will ask for information on EOL management as a prerequisite to obtaining cyber insurance. However, through proper planning and device management, your business can stay sufficiently protected against these known cyber vulnerabilities.
