Breach and Attack Simulation

Breach and Attack Simulation (BAS)

Use real-world threat simulations to evaluate and enhance your cyber defenses.

Breach and attack simulation to test your defenses before real attackers do

SISA’s breach and attack simulation (BAS) service is designed to rigorously test and validate the effectiveness of your organization’s detection and protection mechanisms. Through simulated, harmless attack scenarios – based on real-world tactics – we help you assess the maturity of your cybersecurity posture, identify blind spots, and strengthen your ability to respond.
The ultimate goal? To deliver a detailed maturity assessment of your current defences and provide actionable recommendations to elevate your cyber resilience. What SISA BAS helps you achieve:

Improve detection, minimize risk, and strengthen resilience using SISA’s 3-Stage BAS methodology

Our Breach and Attack Simulation service is a structured, consultative approach designed to validate security effectiveness across your environment. Grounded in real-world tactics and executed with surgical precision, SISA’s BAS framework includes:
01   Internal threat simulation – exposing risks behind the firewall

We simulate adversarial behaviour within your internal network to test security controls on systems not exposed to the internet. These controlled actions are designed to mimic common attacker behaviours and include:

Process invocation and command execution (e.g., PsExec, WMI)

Registry modifications and privilege escalation attempts

User enumeration to assess credential exposure

Deployment via a custom batch file with pre-configured, safe command sets

Reconnaissance using tools like Nmap

Simulated attacks via custom web-based scripts targeting known CVEs, misconfigured assets, or weak authentication controls

Testing detection capabilities without disrupting production environments

Identify a host machine that is already feeding logs into your SIEM

Confirm availability of target systems (Windows, Linux)

Set up necessary admin access and custom configurations

Validate security telemetry across your entire environment

Each simulation is designed not just to mimic adversary behavior but to verify that your detection systems are working as intended. By observing how your tools capture and respond to simulated threats, we help you ensure telemetry is accurate, complete, and actionable. Our BAS exercises validate log collection, alerting, and visibility across:

From simulation to action: Turning insights into security outcomes

SISA’s BAS engagement doesn’t end with simulation, it delivers clarity, direction, and measurable next steps. Once the simulation activities are complete and logs are analysed, you receive a comprehensive report and prioritized roadmap to improve your detection strategy and close critical gaps across people, process, and technology. This includes:
01   Tactic-to-Outcome Mapping
Success/failure ratio of simulations, aligned with MITRE ATT&CK tactics.
Analysis of how specific adversarial behaviors were handled by your environment.
Evaluation of key security controls such as EDRs, firewalls, DLPs, and other critical tools under simulated attack.
Areas of weakness in threat detection, alerting, and response workflows.
Insights into your team’s ability to detect, escalate, and respond
Assessment of current SIEM/SOC use cases against observed telemetry
Suggested baseline detection use cases tailored to each device or system type
Targeted recommendations to improve rule logic, visibility, and alert prioritization
