Security monitoring and alerting

Security monitoring and alerting is a very important use case of ELK Stack as application security is a vital part, and it costs if there are any security breaches in the application since security breaches are becoming more common, and most importantly, more targeted. Although enterprises are regularly trying to improve their security measures, hackers are successful in penetrating the security layers. Therefore, it is very much required for any enterprise to detect the presence of security attacks on their server, and not only detect but also alert them so that they can take immediate actions to mitigate their losses. Using ELK Stack, we can monitor various things, such as unusual server requests and any suspicious traffic. We can gather security-related log information that can be monitored by security teams to check any alerts to the system.

This way, security teams can prevent the enterprise from attackers who have gone unnoticed for a long time. ELK Stack provides a way through which we can gain an insight and make the attacker's life more difficult. These logs can also be very useful for after-attack analysis; for example, for finding out the time of the attack and the method of attack used. We can understand the activities the attacker performed to attack, and this information can provide us with a way to strengthen that loophole easily. In this way, ELK Stack is useful for both before attack prevention and after attack healing and prevention.
