SI-2Flaw Remediation

Identify, report, and correct system flaws; Test software and firmware updates related to flaw remediation for effectiveness and potential side effects before installation; Install security-relevant software and firmware updates within {{ insert: param, si-02_odp }} of the release of the updates; and Incorporate flaw remediation into the organizational configuration management process.

CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-327Use of a Broken or Risky Cryptographic Algorithm700+Flaw remediation replaces broken or risky cryptographic algorithms once safer implementations are released by vendors.
CWE-326Inadequate Encryption Strength500+Prompt patching corrects inadequate encryption strength when vendors release updates that increase key sizes or algorithm security.
CWE-328Use of Weak Hash90Security updates supplant weak hashing algorithms with stronger alternatives before attackers can exploit the original weakness.
CWE-1104Use of Unmaintained Third Party Components26Timely identification and installation of updates directly prevents use of unmaintained third-party components whose known flaws remain exploitable.
CWE-477Use of Obsolete Function16Software and firmware updates replace obsolete functions whose retained presence leaves systems exposed to publicly known weaknesses.
