Comparable Approaches

Blastwall is aimed at privileged automation security. That is a narrower and more useful claim than "Linux sandbox" or "runtime security tool." The critical path is a centrally governed automation identity becoming root on a managed host; Blastwall makes that path constrained, visible, and selectable before the job runs.

Evaluation Question

What is the right tool for privileged automation confinement?

Blastwall is a strong fit when the security problem is enterprise automation reaching many RHEL systems with delegated privilege. It is not trying to beat every low-level control at its own job. BPF LSM is sharper for one kernel hook. seccomp is cleaner for reducing one process' syscall surface. Falco and Tetragon are better places to start when the primary problem is runtime detection or event-rich observability.

The useful comparison is scope fit. For privileged automation security at fleet scale, Blastwall joins the controls that already decide who may run, where they may run, what local domain they enter, and how AAP proves the host is current before touching it.

The Four Parts

The design works because authority is explicit. The policy authority for confinement is the versioned SELinux policy artifact installed on the managed host. IdM records who and what should be in scope. eigenstate.ipa reads that state into inventory facts. AAP acts on the facts and records the run.

System	Role	Authority Line
SELinux policy artifact	Defines and enforces the host-local automation boundary.	Owns the confinement rules and deny scopes on the managed host.
IdM	Records automation identities, host scope, HBAC, sudo, login mapping, and host markers.	Owns identity and access relationships; it does not author the SELinux policy.
`eigenstate.ipa`	Turns IdM records into inventory-visible suitability facts.	Reads and translates state; it does not create access or policy.
AAP	Syncs inventory, runs preflight, launches workflows, and records job logs.	Acts on suitability facts; it does not create confinement by itself.

The Scale Complex

The value is not any single control in isolation. The value is the complex they form together:

IdM authority
  -> inventory facts
  -> AAP preflight
  -> SELinux enforcement
  -> AAP-visible proof

That loop gives privileged automation a lifecycle. A new deny scope can become policy source, a built artifact, a deployed host state, an IdM-visible marker, an AAP preflight condition, and finally a verified runtime result. The enterprise claim is operational: not only "we blocked something," but "we can operate the boundary across the fleet."

Comparable Approaches

Approach	Primary Lever	Best Fit	Why It Is Not The Same Problem	Where It Pairs Well
Blastwall	SELinux, IdM, `eigenstate.ipa`, and AAP	Privileged automation security across managed RHEL fleets.	This is the scoped target: identity authority, inventory truth, AAP gate, host enforcement, and job-log reconciliation after `eigenstate.ipa` checks endpoint suitability.	Pairs with precise mitigations, detection, and isolation as additional layers.
block-copyfail	BPF LSM hook logic	Argument-precise runtime mitigation for the Copy Fail `authencesn` AF_ALG bind path.	It answers the exact kernel-argument question, not the identity, sudo, host suitability, and AAP workflow question.	Use it when Copy Fail precision is required while Blastwall narrows what automation identities can reach.
cfDr	Ansible detection and remediation	Finding and correcting Copy Fail exposure with a focused playbook workflow.	Its center of gravity is exposure handling, not identity-backed confinement before automation runs.	Use response playbooks to find or remediate exposure, then use Blastwall-style markers and preflight for future suitability checks.
seccomp	Syscall filtering	Reducing a process' syscall surface, especially for services and containers with predictable behavior.	It is process-local filtering. The enterprise access decision still needs identity, sudo, inventory, and workflow state.	Use it for stable helper processes inside the automation path when their syscall shape is predictable.
nono	Landlock and platform sandboxing	Constraining AI agents or local development tools inside an allowed workspace.	It is aimed at local workspace or agent boundaries rather than centrally governed privileged fleet automation.	Use it around local tooling that prepares automation content before that content enters the fleet path.
Tetragon	eBPF observability and enforcement	Runtime security observability, especially around process, file, network, and Kubernetes activity.	It starts from observed behavior and runtime policy, not from the identity-to-privilege decision before a job runs.	Use it to observe or enforce runtime behavior around the automation path and alert on abnormal activity.
Falco	Runtime detection rules	Alerting on suspicious host, container, Kubernetes, and cloud behavior.	It detects suspicious behavior. It does not decide which automation identity may arrive in which SELinux domain.	Use it as a detection layer when a confined automation path still behaves unexpectedly.
gVisor	User-space application kernel	Adding a stronger isolation boundary around containerized workloads.	It isolates containerized workloads. Blastwall targets administrative automation landing on existing RHEL hosts through SSH, sudo, IdM, and AAP.	Use it where the workload is containerized and host administrative automation is a separate path.

Scope Verdict

If the scope is privileged automation security, Blastwall fits because it treats privilege as an enterprise relationship, not only as a local process property. The subject is not just a process making a syscall. The subject is an automation identity granted remote access, mapped by central policy, using sudo, running through AAP, and touching a fleet.

The claim stays narrow. Blastwall does not replace block-copyfail for argument-precise Copy Fail mitigation. It does not replace seccomp, gVisor, Falco, or Tetragon in their natural lanes. It gives privileged automation a boundary that lines up with the way RHEL estates are commonly operated: identity first, host enforcement second, automation actuation third, and proof visible to the people running the fleet.
