incident response playbook design question - kykychand - Oct 16, 2025
How do you design an incident response playbook that minimizes lateral spread from an initial virus infection?
RE: incident response playbook design question - Bastille - Oct 16, 2025
An incident response is usually composed of 7 steps :
1 - Preparation
2 - Detection
3 - Analysis
4 - Containment
5 - Eradication
6 - Recovery
7 - Post event (lessons learned, surveillance, etc)
Depending on the threat, the playbook you'll use will be different, but it always uses the steps above.
STEP 1 : PREPARATION
Before going straight into the incident response, you MUST be pro-active and reduce the surface attack or go through hardening. For example, running an audit on your Active Directory servers, going with remediation to fix flaws / vulnerabilities, so in case the server is compromised, the attacker will have more difficulties with lateral movments and you'll slower him.
Few examples : running PingCastle on a Domain Controller, whitelisting only the necessary traffic with the dedicated ports, vlans, follow the principle of least privileges, use dedicated accounts on the AD to run services such as backups, installing an EDR/XDR on every machine, etc.
You also need to prepare your team to counter an attack, let them know about the Incident Reponse procedure (the 7 steps), you need to train them like to be able to conduct an analysis and so on.
STEP 2 : DETECTION
This part depends on your budget, if you have a SOC or not for example, if you've configured alerts on your email services, and so on.
STEP 3 : ANALYSIS
Relies the team's knowledge and skills to be able to find if the threat is real or not.
STEP 4 : CONTAINMENT
That's also where you can avoid lateral movments from the attacker. Think about :
- Changing passwords
- Shutting down NIC (useful if you have physical access)
- Shutting down IPSec VPNs between other sites / offices / customers / supply chain / ...
STEP 5 : ERADICTION
Explicit, be sure to spend enough time on the analysis to understand how the attacker proceeded so you'll fix the vulnerabilities / flaws he used.
STEP 6 : RECOVERY
Explicit
STEP 7 : POST EVENT
Take a look at what worked well, what didn't work very well, try to improve your process, and don't forget to monitor the activity in case it could happen again.
