mAI Action Month \u2013 what free AI cybersecurity tools can do for SMEs without dedicated IT security teams<\/span><\/a><\/div>\nFrequently Asked Questions<\/h2>\n
Every question is locked. A tap unlocks the answer.<\/p>\n\nAre my data as a Trellix customer at risk?<\/strong><\/summary>\nAccording to Trellix\u2019s latest statement, customer data was not directly compromised. The mid-term risk lies at the zero-day level: attackers with source-code knowledge can actively hunt for vulnerabilities to weaponize against customers. Customers should apply Trellix patches with particular urgency going forward.<\/p>\n<\/details>\n\nWhich Trellix products are specifically affected?<\/strong><\/summary>\nTrellix has not yet named specific product lines as affected. The advisory references source-code repositories without detailing which products are involved. Customers should direct specific product inquiries through the official Trellix support channel.<\/p>\n<\/details>\n\nHow does vendor due diligence for security tools differ from regular software?<\/strong><\/summary>\nBy definition, security tools have privileged access to systems \u2013 network traffic, credential stores, and kernel-level access on endpoints. A compromised security tool is therefore more dangerous than compromised business software. Vendor due diligence for security tools must answer: what can the vendor do in an emergency on our systems \u2013 and how can we disable it in a controlled way?<\/p>\n<\/details>\n\nDo we need to replace Trellix now?<\/strong><\/summary>\nNo \u2013 a hasty replacement would be overkill and introduce new risks through rushed migration. The right response is heightened vigilance: apply patches immediately, minimize privileged access, and sharpen monitoring of Trellix agent activity. If the vendor fails to deliver a clear forensic report promptly, a mid-term reassessment makes sense.<\/p>\n<\/details>\n\nWhat is a vendor compromise plan and how do I start one?<\/strong><\/summary>\nA vendor compromise plan defines for each critical security tool: (1) which access paths the vendor has to our systems, (2) how those accesses can be shut down in an emergency, and (3) what alternate controls exist if the tool is disabled. This plan should cover all Tier-1 security tools, not just Trellix.<\/p>\n<\/details>\n
