#CYLANCE ANTIVIRUS FAILS UPDATE#
Starting with the update to macOS High Sierra version 10.13.2, a new security feature requires users to approve new applications that interact with the kernel, a core part of the operating system. This approach offers a much higher level of protection against zero-day malware, and it takes away the complexity that would otherwise be involved when managing a traditional signature-based anti-malware solution.Update: macOS Big Sur (11.x) is now supported by Cylance Smart Antivirus version 1580 and later. This is usually a manual effort and neither signatures nor human intervention are impervious to errors.ĬylancePROTECT doesn’t rely on signatures, but instead, it harnesses the power of machine learning. Testing those new signature definitions would be essential for each update, as there is no other way to verify compatibility with existing applications. This is usually a task that a human has to undertake at regular intervals in order to manage risk and to keep network bandwidth usage low (generated by automatic updates to definition files). A signature update means that a golden image is then outdated and therefore, a (partial) rebuild of said image is required. Given the frequency at which zero-days are being released into the wild, these definition updates are released at least once a day. If administrators fail to do so, they will find themselves at risk of running out of date virus definitions, which would, in turn, imply a significant risk to enterprises due to a lack of coverage for new(er) threats. Traditional anti-malware solutions require administrators to keep up with the latest threat updates all the time.
