Deep packet inspection (DPI), as the name suggests, is a type of network packet filtering and an advanced mode of examining network packets. In DPI, network packets that are transmitted through an inspection point are evaluated. At this inspection point, a DPI tool determines where the packets came from, whether a service or application. With DPI, packets are categorized, inspected, and redirected to prioritize business-critical applications and other online services.
CISA released in late February a cybersecurity advisory on the key findings from a recent Cybersecurity and Infrastructure Security Agency (CISA) red team assessment to provide organizations recommendations for improving their cyber posture. According to the Agency, the necessary actions to harden their environments include monitoring network activity to spot abnormal behavior, conducting regular assessments and drills, and enforcing phishing-resistant MFA anywhere possible.
