Patching Applications is often overlooked in the security strategy of organisations. While patching operating systems is a regular task, business focused applications that are relied on daily end up being forgotten. Productivity software on the desktop, critical payroll and HR applications, and even the system firmware and software on network appliances (physical and virtual) must be updated and patched to the current stable versions as part of your patch management strategy. Replace or remove unsupported systems. Acquire updates from vendors when available and consider underpinning support agreements. Compromise of a vulnerable application can quickly escalate to exploiting your entire infrastructure.
