An anomaly-based IDS can identify unknown attacks by monitoring system activity and classifying it as either normal or anomalous. This classification is based on heuristics or rules, rather than patterns or signatures, which allows it to detect new, previously unknown threats. In contrast, signature-based IDS can only detect attacks for which a signature has previously been created, thus limiting their ability to identify new threats.

These identifiers help ensure standardized and secure transactions within the healthcare and administrative systems.

In Wireshark, the packet bytes pane shows the data of the current packet in a hexdump style. This means the data is presented in a hexadecimal format, which is commonly used for representing binary data in a more readable way.

DNSSEC is a set of extensions to DNS that provide origin authentication of DNS data to DNS clients (resolvers) to reduce the threat of DNS poisoning, spoofing, and similar attacks. It strengthens authentication in DNS using digital signatures based on public key cryptography, ensuring the integrity and authenticity of the DNS data.
