Privileged Threat Analytics
Introduktion
Privilegeret Threat Analytics registrerer unormal
privilegeret konto adfærd.
PTA detektere og identificere uregelmæssigheder mens
de sker, ved i realtid at sammenholde aktuelle
privilegeret aktivitet med historisk aktivitet.
Det gør muligt for et incident response team til at
reagere og afværge angrebet før der er sket alvorlig
skade.

Privileged Threat Analytics
Hvorfor?
▶ Identificer igangværende avancerede angreb
– Målrettede analyse af privilegeret konto aktivitet
– Alarmer baseret på realtid data
▶ Bedre forståelse af det aktuelle trusselsniveau
– Real-time baseret detektering
– Korrelation af begivenheder
– Klassificering af trusseler af sværhedsgrad
▶ Forbedre effektiviteten SIEM system
– SIEM er centreret om sikkerhedsspørgsmål rapporteret fra
mange kilder
Privilegeret Threat Analytics er fokuseret på at identificere
mistænkelige privilegeret brugeraktivitet
– Komplementerende, ikke alternativt til SIEM

Privileged Threat Analytics
UM Fordele
▶ Evne til at opdage og alarmere på skadelig adfærd
– Reducerer tidshorisonten for hackerens mulighed
– Muliggør en hurtig og præcis indsats for at stoppe angreb
▶ En løsning til at opdage både eksterne og interne trusler
▶ Ingen afhængighed af signatur, sandboxing eller andre metoder, der kræver
forudgående kendskab til angrebet
▶ Tilpasser sig over tid til ændringer i brugeradfærden
▶ Forbedrer effektiviteten af SIEM, at fokusere på den aktivitet, der virkelig
betyder noget
– Reducerer falske positiver
▶ Pragmatisk tilgang til analyse
– De "rigtige" data vs. "alle" de data

Lesson Learned
▶
▶
▶
▶
▶
Start småt
Tænk stort og i sammenhængende løsninger
Fase opdelt implementering med “mange” små leverancer
Bruge live POC til at afdække ukendte og komplekse aspekter
Organisatorisk implementering
• Sikkerhed er ikke sexet, kræver ledelsesopbakning
• Dedikeret system ejer
• Begrænset antal af administratorer
▶ Husk undtagelserne
