Patch и vulnerability management
Систематично откриване, приоритизиране и отстраняване на known vulnerabilities.
Какво е
Систематично откриване, приоритизиране и отстраняване на known vulnerabilities.
Как работи
Inventory + scanning + threat intelligence + remediation SLA. Приоритетът трябва да отчита exploitation, exposure и business criticality, не само CVSS.
CVSS не е опашка за чакане
Две уязвимости с CVSS 9.8 не са непременно еднакво спешни. Важно е:
- има ли active exploitation;
- asset-ът internet-facing ли е;
- има ли exploit path до critical systems;
- има ли compensating controls;
- колко важна е системата.
Пример
Критична уязвимост в лабораторен isolated host може да е по-малко спешна от CVSS 8.x в публичен VPN gateway, който вече се експлоатира масово.
Как да проверим процеса
Не измервайте само „% patched“. Измервайте:
- time-to-remediate за KEV/internet-facing;
- exposure age;
- failed patches;
- assets без owner;
- изключения без expiration.
Практическа имплементация
- Asset inventory.
- Internet-facing assets first.
- CISA KEV/EPSS-informed prioritization.
- Emergency patch process.
- Compensating controls при невъзможен patch.
- Verify remediation, не само ticket closure.
Какво НЕ решава
Не решава zero-days, misconfiguration или stolen credentials.
