To keep your IT systems safe from cyber threats that are always changing, you need to have something watching over them at all times. Security Information and Event Management (SIEM) is like a digital security guard that never sleeps. It monitors every single network device and application you have 24/7 by collecting logs and analyzing events to detect possible breaches in security.
They are smart software programs that constantly monitor your network hardware as well as applications to protect against any new types of security risks before they can do any damage.
What is SIEM?
Think of a central nervous system for IT security in an organization – that’s what Security Information and Event Management (SIEM) does essentially. It works as if it were the security operations command center collecting information from every device and application throughout the network. But more than just gathering data though, this platform analyzes it for signs of unusual activity that might signify an upcoming attack before any real damage happens thus enabling defense teams to respond proactively against such threats rather than reactively after they have already caused harm.
Why Do We Require SIEM Tools
We need these tools because managing the cyber defense posture of an organization is like looking for a needle in a haystack – a very big one made up entirely of data. The traditional method involves manually going through logs from devices, user activity, applications, etc., which takes time and may miss important details.
Here comes SIEMS, they automate all this work by collecting such kind of information and then analyzing it for abnormal patterns hence generating alarms just like digital security analysts who work round-the-clock throughout week even during holidays . So instead of being overwhelmed with too much input that has no value at all what should be done?
