Introduction
End-of-life (EOL) software presents a significant challenge for organizations [1], as many continue to rely on applications that no longer receive security updates. This reliance increases vulnerability to security threats, necessitating proactive measures to address the issue.
Description
End-of-life (EOL) software is a significant concern for organizations [1], with nearly two-thirds still relying on applications that no longer receive security updates [1]. This reliance exposes critical systems to vulnerabilities [1], making it essential for businesses to address the issue [1]. For instance, as of January 14, 2020 [2], Microsoft discontinued support for Windows 7 and Windows Server 2008 R2 [2], with support for Windows 8.1 ending on January 10, 2023 [2], and for Windows Server 2012 and 2012 R2 on October 10, 2023 [2]. Computers and servers running these legacy operating systems are particularly at risk [2], as they will no longer receive security updates or technical support [2], heightening their vulnerability to security threats.
Cost is a primary reason for the continued use of unsupported legacy applications [1], as many companies are reluctant to invest in updates or replacements due to perceived high costs and potential disruptions [1]. However, the financial savings from maintaining EOL software can quickly be overshadowed by the costs associated with data breaches [1], which are likely to be more severe when using outdated [1], unsupported systems [1]. The absence of security updates increases the risk of threats, and while solutions like Managed Antivirus AVD can offer some protection, they cannot replace the critical security updates provided by Microsoft.
EOL software often persists unnoticed [1], as administrators may not be aware of its presence [1]. Communication failures from vendors regarding software support status can contribute to this issue [1]. Additionally, shadow IT complicates the situation [1], with a significant percentage of companies allowing employees to access resources from unmanaged devices [1], potentially harboring EOL software [1].
To combat EOL software [1], organizations should conduct comprehensive audits of all software in use [1], including on personal devices [1]. Tools like APIs can help monitor EOL status [1], while agents can assist in identifying installed EOL software [1]. Establishing ownership of EOL remediation is crucial to integrate it into existing patch management and compliance strategies [1].
Transitioning away from EOL software requires careful planning and clear communication to address concerns from leadership and end users [1]. Implementing policies to block devices running EOL software [1], while educating users about the associated risks [1], is essential [1]. Collaboration across the organization is necessary to effectively manage the challenges posed by EOL software [1], especially as the landscape of supported systems continues to evolve.
Conclusion
The continued use of EOL software poses significant security risks and potential financial repercussions for organizations. To mitigate these risks, it is imperative to conduct thorough software audits, establish clear ownership of remediation processes, and implement robust policies and education programs. As the technological landscape evolves, organizations must remain vigilant and proactive in managing their software environments to ensure security and compliance.
