After the Brown University attack, elite institutions including Harvard and Yale announced stepped-up security, and colleges nationwide ordered reviews of campus access and emergency protocols. Administrations cited coordination with local police and temporary measures such as increased patrols and restricted building access. Some Ivy League leaders said there were no specific external threats but moved quickly to limit risk during finals and holiday departure periods. Reporting highlighted specific vulnerabilities at Brown’s Barus & Holley building—limited camera coverage and unlocked exterior doors during exam periods—that investigators say may have constrained the initial response. The disclosures have prompted many campuses to reassess physical security investments, badge-access policies, and surveillance deployments amid a renewed debate over the balance between open-campus norms and threat mitigation.
