In the United States, the National Institute of Standards and Technology (NIST) offers a cybersecurity framework to help IT providers and stakeholders secure critical infrastructure.5The US Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) also provides guidance.6...
CISA’s model represents a gradient of implementation across those key pillars “where minor advancements can be made over time toward optimization.” Organizations can take isolated steps focusing on one pillar at a time, with each category progressing at its own pace until cross-coordination is r...
One example of a CSSC is the US Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) that provides cybersecurity services to federal, state, and local government agencies, as well as critical infrastructure organizations.What types of cybersecurity services does a...
Achieving zero trust is a continuous journey, not a one-time project. You don’t have to reinvent the wheel, either—consider using one of the models from NIST, CISA, DISA, or NCSC as a technical roadmap. From a project level, plan to implement zero trust in a phased manner to minimi...
CISA recommends distributed ingress/egress microperimeters and extensive microsegmentation based on application architectures, with dynamic just-in-time and just-enough connectivity. This doesn’t mean firewalls everywhere. Microsegmentation techniques include virtual machines for each application, east/west ...
CISA's Zero Trust Maturity Model outlines the three stages of zero-trust adoption, along with the five pillars that must progress as the stages advance. Once an organization is ready to adopt zero trust, it is highly beneficial to approach it in phases. The following are seven steps to impl...
CISA will enhance real-time threat monitoring across federal networks, improving visibility and response times. New encryption requirements will secure government email, DNS traffic, and communication channels against cyber espionage. The goal is to reduce unauthorized access risks by enforcing modern secur...
Section 2 (Removing Barriers to Sharing Threat Information) directs that the Federal Acquisition Regulation (FAR), which defines the contractual rules to conduct business with the Federal Government, be updated to require the sharing of threat and incident information with CISA. This contractually obli...
The term cyberspace was initially introduced byWilliam Gibsonin his 1984 book, Neuromancer. Gibson criticized the term in later years, calling it “evocative and essentially meaningless.” Nevertheless, cyberspace is still widely used to mean any feature linked to theInternet. People use the term to...
Patching vulnerabilities across the business environment is a time-sensitive activity. The United States' Cybersecurity and Infrastructure Security Agency (CISA) advises organizations to patch vulnerabilities within 15 days. Prominent organizations can be targeted by malicious actors in a short window of ...
