Merge branch 'topic/bbannier/docker-multistage'
Benjamin Bannier(11 Aug 26)
Use regular Dockerfile instead of shell-orchestrated build pipeline We previously used a rather complicated setup of building multiple Docker images, all orchestrated by a `Makefile`. This seems to have been done to be able to use ccache when building the images in CI. At the same time, this made local running without the `Makefile` hard and pretty obscure (e.g., exact sequence of shell commands required, but `docker` hardcoded in `Makefile` and little regard for existing tags or tag pollution). This patch replaces what we have with a less unusual setup where on can directly invoke e.g., `docker build -f docker/Dockerfile ...` to produce a working container image. The only feature we loose is reliable caching of compiler artifacts in CI, but we keep that functionality for local runs by using a layer cache. Given that we only rebuild the Docker image for merges to `master` this seems an acceptable trade-off to me, especially since the local workflow becomes less awkward. Other than caching this should produce identical images.

btest/Traces: Use Scapy for new ldap generator scripts This was done by Opus 4.8. There's a Scapy API for LDAP, but it said the Abandon and Delete requests didn't work out.

ldap: Fix DelRequest using implicit tagging Similar to AbandonRequest, the DelRequest directly contains the LDAPDN octetstring. PCAP generator script taken from #5795 directly.

ldap: Fix AbandonRequest using implicit tagging The integer is encoded directly within an AbandonRequest. The included messageId is at most 4 bytes long (32 bit). PCAP generator script taken from #5795 directly.

Modernize ReaderFrontend::name to std::string Replace the raw char* name member with std::string, removing the manual copy_string/delete[] lifecycle and the dependency on util::fmt()'s static buffer.

Merge branch 'topic/christian/5833-disable-broker-identifier-updates' * topic/christian/5833-disable-broker-identifier-updates: Disable Broker's identifier updates by default
Christian Kreibich(28 Aug 26)
Disable Broker's identifier updates by default Zeek now drops transmission and receipt of Broker `IndentifierUpdate` messages by default, to prevent one class of unintended runtime updates to Zeek configuration settings. Reporter errors result instead. The new `Broker::enable_identifier_updates` toggle, defaulting to false, allows restoring the original behavior. The Control framework's `configuration_update` command, the sole known user of identifier updates, now errors out in the controller when updates are disabled.

Dict: Switch location info to get_current_script_location() or no_location detail::GetCurrentLocation() is for parse time location information and not better than no_location.
Arne Welzel(26 Aug 26)
Dict: Include better location info for distance-too-far error The new detail::get_current_script_location() only works in non-ZAM environments, use no-location as a fallback otherwise. Will still include the script call stack.

More Intrusion Detection
An 802.11 layer2 wireless network detector, sniffer, and intrusion detection system.
OSSEC is an Open Source host-based intrusion detection system, that performs log analysis, integrity checking, monitoring, rootkit detection, real-time alerting and active response.
picosnitch helps protect your security and privacy by "snitching" on anything that connects to the internet, letting you know when, how much data was transferred, and to where. It uses BPF to monitor network traffic per application, and per parent to cover those that just call others. It also hashes every executable, and will complain if some mischievous program is giving it trouble.
SNARE (System iNtrusion Analysis and Reporting Environment) is a series of log collection agents that facilitate centralized analysis of audit log data. Logs from the OS are collected and audited. Full remote access, through a web interface easy to use manually, or by an automated process.
