API authorization testing asks a narrower and more important question than “can the user log in?” Authentication proves an identity; authorization decides what that identity is allowed to read, change, invoke, approve, or administer. A test can therefore pass every authentication check and still expose another customer’s record, an administrator-only function, or a field that […]

Kerberos is designed to let users and services authenticate across a trusted domain without repeatedly sending a password to each server. In Windows environments, the Key Distribution Center on a domain controller issues a ticket-granting ticket after initial authentication, and the client later obtains service tickets for specific services. That efficiency and delegation model also […]

NTLM relay is dangerous because an attacker does not need to learn the user’s password or crack a captured response before abusing it. If a victim is induced to authenticate to an attacker-controlled intermediary, that authentication can sometimes be forwarded to another service that accepts NTLM without sufficient protection against relaying. The attacker is exploiting […]

A cryptographic key is valuable because possession of the key can enable decryption, signing, authentication, or another security function. Protecting the algorithm while mishandling the key defeats the purpose of cryptography. The cryptographic key lifecycle therefore covers every stage from generation through use, rotation, compromise response, archival, and final destruction. Each stage has different operational […]

The Model Context Protocol (MCP) standardizes how AI applications connect to tools, resources, and related capabilities. That interoperability is useful precisely because it reduces custom integration work. It also means organizations can accumulate many servers, tool catalogs, credentials, extensions, and client implementations faster than traditional integration governance processes expect. MCP governance is the discipline that […]

Security architecture is the work of turning business risk, system constraints, and trust assumptions into a design that can survive real failures. It is broader than choosing security products and more concrete than writing policy. Architecture decides where trust begins and ends, how identities are verified, how data is classified and protected, which components may […]

Security operations teams do not struggle only with detecting incidents; they struggle with deciding what deserves attention first. Cortex XDR incident scoring addresses that queue-management problem by attaching a numeric urgency signal to an incident, but the score is useful only when the organization understands how it is produced and what operational decision it is […]

Cortex XDR causality chains are designed to solve one of the hardest parts of endpoint investigation: connecting a detection to the sequence of activity that produced it. An alert can identify a suspicious process or behavior, but the investigator still needs to understand what launched it, what it launched next, which network connections and file […]

Alert correlation is one of the central promises of a modern SOC platform: turn many low-level signals into a smaller number of investigations that represent meaningful activity. Cortex XSIAM supports that goal in more than one way. It can stitch related alerts through platform context such as causality, and it can also run explicit correlation […]

Threat hunting in Cortex XDR is not the act of running broad queries until something looks unusual. It is a disciplined process for testing a security hypothesis against endpoint and related telemetry, validating what the results mean, and deciding whether the finding should expand into an incident, a new detection, or no action at all. […]

Cortex XSOAR playbooks can automate enrichment, triage, containment, notification, evidence collection, and many of the repetitive transitions in an incident workflow. The hard part is not drawing a sequence of tasks. It is designing automation that remains predictable when inputs are incomplete, integrations fail, cases take unexpected branches, and an analyst needs to understand exactly […]

FortiSIEM correlation rules turn streams of normalized security events into incidents by expressing relationships that matter to the SOC. A rule can look for repeated behavior, sequences across subpatterns, thresholds, or conditions that become meaningful only when several events are evaluated together. The technical editor makes those relationships configurable, but useful correlation still depends on […]

FortiSOAR case management is where alert records, incident ownership, tasks, evidence, collaboration, and automation become an operational workflow. The platform can receive large numbers of alerts, but a SOC still needs a consistent method for deciding which alerts become incidents, who owns the investigation, what evidence must be preserved, which tasks are required, and what […]

API protection requires a different security posture from simply applying web-application rules to traffic that happens to use HTTP. APIs expose structured interfaces, machine identities, predictable schemas, and high-volume automated access. Attackers can abuse that structure with malformed objects, unexpected fields, excessive requests, stolen tokens, or calls to endpoints that were never meant to be […]

Cisco Secure Firewall policy design is the work of translating business access requirements into an ordered control system that can be reviewed, deployed, monitored, and changed safely. An access control policy can match traffic by network attributes, applications, users, security groups, URLs, and other context, but additional matching options do not automatically create better security.
