In today’s increasingly interconnected world, businesses of all sizes are facing an ever-growing threat of cyber attacks. As a result, network intrusion detection software (IDS) has become an essential tool for protecting networks from malicious activity.
An IDS is a device or software application that monitors a network for malicious activity or policy violations. It does this by collecting data about network traffic and then analyzing that data for signs of attack.
If the IDS detects suspicious activity, it can raise an alert or take other action to prevent the attack from succeeding.
