Enterprise Tier Features#

This document describes the Enterprise tier features of DaemonEye, including kernel monitoring, network event monitoring, and federated security center architecture.

Overview#

The Enterprise tier extends DaemonEye with advanced monitoring capabilities and enterprise-grade features:

Kernel Monitoring Layer: eBPF, ETW, and EndpointSecurity integration
Network Event Monitor: Real-time network traffic analysis
Federated Security Center: Multi-site security center architecture
STIX/TAXII Integration: Threat intelligence sharing
Advanced Analytics: Machine learning and behavioral analysis

Kernel Monitoring Layer#

Linux eBPF Integration#

DaemonEye uses eBPF (Extended Berkeley Packet Filter) for low-level system monitoring:

use aya::{
    Bpf,
    programs::{Xdp, XdpFlags},
};

pub struct EBPFMonitor {
    bpf: Bpf,
    program: Xdp,
}

impl EBPFMonitor {
    pub async fn new() -> Result<Self, MonitorError> {
        let bpf = Bpf::load_file("monitor.o")?;
        let program: &mut Xdp = bpf.program_mut("monitor").unwrap().try_into()?;
        program.load()?;
        program.attach("eth0", XdpFlags::default())?;

        Ok(Self { bpf, program })
    }
}

Windows ETW Integration#

Windows Event Tracing for Windows (ETW) provides comprehensive system monitoring:

use windows::{Win32::System::Diagnostics::Etw::*, core::PCWSTR};

pub struct ETWMonitor {
    session_handle: TRACEHANDLE,
    trace_properties: EVENT_TRACE_PROPERTIES,
}

impl ETWMonitor {
    pub fn new() -> Result<Self, MonitorError> {
        let mut trace_properties = EVENT_TRACE_PROPERTIES::default();
        trace_properties.Wnode.BufferSize = std::mem::size_of::<EVENT_TRACE_PROPERTIES>() as u32;
        trace_properties.Wnode.Guid = GUID::from("12345678-1234-1234-1234-123456789012");
        trace_properties.Wnode.ClientContext = 1;
        trace_properties.Wnode.Flags = WNODE_FLAG_TRACED_GUID;
        trace_properties.LogFileMode = EVENT_TRACE_REAL_TIME_MODE;
        trace_properties.LoggerNameOffset = std::mem::size_of::<EVENT_TRACE_PROPERTIES>() as u32;
        trace_properties.LogFileNameOffset = 0;
        trace_properties.BufferSize = 64;
        trace_properties.MinimumBuffers = 2;
        trace_properties.MaximumBuffers = 2;
        trace_properties.FlushTimer = 1;
        trace_properties.EnableFlags = EVENT_TRACE_FLAG_PROCESS;

        let session_handle = StartTraceW(
            &mut 0,
            PCWSTR::from_raw("DaemonEye\0".as_ptr() as *const u16),
            &mut trace_properties,
        )?;

        Ok(Self {
            session_handle,
            trace_properties,
        })
    }
}

macOS EndpointSecurity Integration#

macOS EndpointSecurity framework provides real-time security event monitoring:

use endpoint_sec::{Client, ClientBuilder, Event, EventType, Process};

pub struct EndpointSecurityMonitor {
    client: Client,
}

impl EndpointSecurityMonitor {
    pub async fn new() -> Result<Self, MonitorError> {
        let client = ClientBuilder::new()
            .name("com.daemoneye.monitor")
            .build()
            .await?;

        Ok(Self { client })
    }

    pub async fn start_monitoring(&self) -> Result<(), MonitorError> {
        let mut stream = self
            .client
            .subscribe(&[
                EventType::NotifyExec,
                EventType::NotifyFork,
                EventType::NotifyExit,
                EventType::NotifySignal,
            ])
            .await?;

        while let Some(event) = stream.next().await {
            self.handle_event(event).await?;
        }

        Ok(())
    }
}

Network Event Monitor#

The Network Event Monitor provides real-time network traffic analysis:

use pcap::{Capture, Device};

pub struct NetworkMonitor {
    capture: Capture<Device>,
}

impl NetworkMonitor {
    pub fn new(interface: &str) -> Result<Self, MonitorError> {
        let device = Device::lookup()?
            .find(|d| d.name == interface)
            .ok_or(MonitorError::DeviceNotFound)?;

        let capture = Capture::from_device(device)?
            .promisc(true)
            .buffer_size(65536)
            .open()?;

        Ok(Self { capture })
    }

    pub async fn start_capture(&mut self) -> Result<(), MonitorError> {
        while let Ok(packet) = self.capture.next() {
            self.process_packet(packet).await?;
        }
        Ok(())
    }
}

Federated Security Center Architecture#

The Federated Security Center enables multi-site security center deployment:

pub struct FederatedSecurityCenter {
    primary_center: SecurityCenter,
    regional_centers: Vec<RegionalSecurityCenter>,
    federation_config: FederationConfig,
}

pub struct FederationConfig {
    pub primary_endpoint: String,
    pub regional_endpoints: Vec<String>,
    pub sync_interval: Duration,
    pub conflict_resolution: ConflictResolution,
}

pub enum ConflictResolution {
    PrimaryWins,
    TimestampWins,
    ManualReview,
}

STIX/TAXII Integration#

DaemonEye integrates with STIX/TAXII for threat intelligence sharing:

use stix::{
    objects::{Indicator, Malware, ThreatActor},
    taxii::client::TaxiiClient,
};

pub struct STIXTAXIIIntegration {
    client: TaxiiClient,
    collection_id: String,
}

impl STIXTAXIIIntegration {
    pub async fn new(endpoint: &str, collection_id: &str) -> Result<Self, IntegrationError> {
        let client = TaxiiClient::new(endpoint)?;
        Ok(Self {
            client,
            collection_id: collection_id.to_string(),
        })
    }

    pub async fn fetch_indicators(&self) -> Result<Vec<Indicator>, IntegrationError> {
        let objects = self
            .client
            .get_objects(&self.collection_id, "indicator")
            .await?;

        let indicators: Vec<Indicator> = objects
            .into_iter()
            .filter_map(|obj| obj.try_into().ok())
            .collect();

        Ok(indicators)
    }
}

Advanced Analytics#

Enterprise tier includes machine learning and behavioral analysis:

pub struct BehavioralAnalyzer {
    models: Vec<BehavioralModel>,
    anomaly_threshold: f64,
}

pub struct BehavioralModel {
    name: String,
    features: Vec<String>,
    model: Box<dyn Model>,
}

impl BehavioralAnalyzer {
    pub fn analyze_process(&self, process: &ProcessInfo) -> Result<AnomalyScore, AnalysisError> {
        let features = self.extract_features(process);
        let mut scores = Vec::new();

        for model in &self.models {
            let score = model.model.predict(&features)?;
            scores.push(score);
        }

        let anomaly_score = self.aggregate_scores(scores);
        Ok(anomaly_score)
    }
}

Deployment Considerations#

Resource Requirements#

Enterprise tier features require additional resources:

CPU: 2+ cores for kernel monitoring
Memory: 4+ GB for network monitoring and analytics
Storage: 100+ GB for event storage and analytics data
Network: High-bandwidth for network monitoring

Security Considerations#

Kernel monitoring requires elevated privileges
Network monitoring may capture sensitive data
Federated architecture requires secure communication
STIX/TAXII integration requires secure authentication

Performance Impact#

Kernel monitoring: 2-5% CPU overhead
Network monitoring: 5-10% CPU overhead
Analytics processing: 10-20% CPU overhead
Storage requirements: 10x increase for event data
