Having the right technologies in place can help you to detect information security threats. Identity and Access Management solutions, for example, can help you to recognise the kind of activities that are usual for your network, and alert you to discrepancies that may indicate an attack. However, when it comes to threats to information security, prevention is definitely better than cure, and putting measures in place to train your teams and protect your business will be a lot more effective than retroactively trying to protect your data once an attacker has gained access to your systems.
