2021 Predictions: Ransomware Escalation
In October 2020, the Department of the Treasury issued an advisory stating that
facilitating ransomware payments with a Sanctions Nexus could result in legal
ramifications or fees, starting us off on the path to trying to curb the rapid
increase in ransom payments. This is an escalation toward trying to reduce
ransomware payments, but it also puts victims in an even tighter spot as they
are often paying for data to not go public more than to recover from the
encryption and disruption to their environments. Escalation is needed, but not
after a company has already fallen victim. In 2021, we will see this escalation
continue, but it will take shape as more clearly defined steps companies should
be taking and fines or ramifications if they fail to do their due diligence.

2021 Predictions: User is the new Perimeter
The world has been shifting away from traditional networks to hybrid cloud-
prem and device agnostic, an existing trend that was accelerated by COVID-19.
Since COVID, perimeters have changed more drastically. Threat actors will
continue to target remote workers. Remote Desktop Protocol (RDP) and Virtual
Private Network (VPN) technologies alone will leave companies exposed. To
regain control and provide more fluid perimeters to securely control who has
access to applications and data, companies will turn to Zero Trust Access
Control.

2021 Predictions: Vulnerability Lifecycle
Management
 Vulnerability remediation will continue to be a struggle for many organizations.
The median time to cre
ate a functional exploit is 22 days. The average shelf life of an exploit is seven
years. Threat actors can move faster than most companies and are getting long
life out of the exploits they create. To stay ahead of attackers, companies will
look to improve visibility and telemetry to understand trending exploits and to
mitigate or eliminate these vulnerabilities to significantly reduce their exposure.

mitigate it within the uninstall window by going back to your previous version of
