Taking an example, an organization that is successfully thwarting a cyberattack can experience a security incident however not a breach.
How Can You Detect Security Incidents?
Nowadays, there is one of the other new headlines regarding high profile data breaching. However, there are way too many incidents that go away unnoticed as the businesses are not aware of how to detect the same. With the help of IT infrastructure consulting services, you can do the same in a flexible manner.
Measures For Detection Of Security Incidents
- Cases of creepy behavior from reliable user accounts
