Abstract: System and computer-implemented method for scanning software-defined data centers (SDDCs) for vulnerabilities uses at least one vulnerability detector listed on vulnerability scan definitions for the vulnerabilities to scan at least one component in each of target SDDCs. Each of the vulnerability scan definitions specifies at least one triggering condition for determining a specific vulnerability using the at least one vulnerability detector. An alert is then generated for each vulnerability found in the target SDDCs so that a remediation is performed to resolve that vulnerability.

Abstract: An electrocatalyst ink comprising one or more electrocatalyst metals and one or more proton-conducting polymers, characterised in that the electrocatalyst ink further comprises particulate graphite which is present at a loading of 1 to 40 weight % with respect to the weight of the electrocatalyst, and a process for the preparation of said ink is disclosed. The use of the ink in a gas diffusion electrode, particularly for use in PEM fuel cells is also disclosed.
