Table 2: January 2021 Security Patches
Patching is vital. Organizations today face the trade-off between speed and perfection. It has become unrealistic to delay a software release until the product is perfect. Therefore, security is compromised and the product gets shipped with vulnerabilities.
The only solution is to be more proactive and properly remediate vulnerabilities using risk-based vulnerability management and deploy a secure product. Be cyber smart by adopting attack surface management for patching instead of battling the attacks.
