An Indicator of Compromise (IoC) is a forensic artifact that is found on a network or host that suggests – with high confidence – that an intrusion has taken place. IoCs are observable and can be directly linked to measurable events. Some examples of IoCs include hashes of known malware, signatures of malicious network traffic, URLs, or domains that are known to distribute malware.
Those are just snippets of the mighty Defender’s arsenal! Whether it’s scaling up your security as your business flourishes, running a tight ship with seamless other-software integrations, or making sure that every device in your fleet is guarded by this vigilant protector – Microsoft Defender is not just a tool, it’s an extension of your commitment to cybersecurity.
