*CISA Updates Internet Exposure Reduction Guidance [ https://www.cisa.gov/r= esources-tools/resources/exposure-reduction?utm_source=3DInternetExposureRe= ductionGuidanceUpdate&utm_medium=3DGovDelivery ]*

Cybersecurity and Infrastructure Security Agency (CISA) has updated its Int= ernet Exposure Reduction Guidance [ https://www.cisa.gov/resources-tools/re= sources/exposure-reduction?utm_source=3DInternetExposureReductionGuidanceUp= date&utm_medium=3DGovDelivery ] to help organizations identify internet-acc= essible systems, remove unnecessary exposure, and secure required remote ac= cess.

Many organizations unknowingly expose information technology (IT) and opera= tional technology (OT) assets to the internet, including remote access tech= nologies, industrial control systems (ICS), supervisory control and data ac= quisition (SCADA) systems, programmable logic controllers (PLCs), and other=
connected devices. Threat actors can use internet-based search and discove=
ry platforms to identify publicly accessible systems with misconfigurations=
, default credentials, and outdated software.

CISA encourages organizations to routinely assess their internet-accessible=
assets, verify third-party remote access, remove unnecessary exposure, and=
secure required access using strong passwords, multifactor authentication,=
security patching, traffic monitoring, and a secure gateway, firewall, VPN=
, or other centrally managed access solution.

For more information, review the updated Internet Exposure Reduction Guidan= ce. CISA also offers Cyber Hygiene Services and regional Cybersecurity Advi= sors to help organizations reduce exposure and strengthen cybersecurity.
