EXECUTIVE SUMMARY Cyber criminals are taking advantage of vulnerable supply chains, digital transformation efforts, distributed operations, and the ongoing post-pandemic upheaval to increase attack’s on financial services institutions and their providers. Exploits have shown that sophisticated attackers will find a way onto your network—and complex, hybrid computing infrastructures make detecting nefarious activity within the network more difficult because of a lack of visibility. The question organizations must ask is: How would you know if your network was compromised? This paper discusses the challenges financial institutions can face when working to mitigate these risks. It offers practical advice on how to detect both known and unknown attacks and ensure your network is protected.
