more safe
SLA
have clauses that relate to how much to pay and the responsibilities for both the client and sponsor
(service level agreements)
risks
survey by Trend Micro: 43% security lapse or issue in 2000s
1. providers
2.tenants
3.transmission of data
key management issues and authentication issues
constant encryption and decryption is more expensive
current encryption less service-level without the need of it being decrypted
criminal attacks
malware and DDos
domain name system attacks
data compromise
access management issues
session hijacking
man-in-the-middle attacks
packet sniffing
