ICMP is evil. Firewalls can be configured default-permit. Firewalls can be configured unidirectionally. Firewalls will solve our security issues. Antivirus will solve our security issues. IDS/IPS will solve our security issues. Audits and checklists will solve our security issues. Our network will never emit abuse or attacks. Our users can be trained. We must do something; this is something; let's do this. We can add security later. We're not a target. We don't need to read our logs. What logs?
