These days security breaches, vulnerabilities and threats seem to be in the news more frequently than ever before. The foremost concern that comes to mind is what best you can do to protect your network from data breaches. Attackers and hackers don’t seem to take a break. Hence it becomes all the more important to stay hawk-eyed on our network rather than being reactive after the damage is done. You know that every device, every system on your network generates tons of logs. Have a centralized solution in place to monitor them, analyze them and responding them is the way to go.
Security Information and Event Management (SIEM) has emerged and come a long way by playing a major part in your security strategy. It spans across regulatory compliance, log management and analysis, troubleshooting and forensic analysis. Typically it starts by classifying your IT assets based on the information that they contains, and then collating relevant information to provide meaningful context.
So the core aspects that you need to consider when you are choosing a SIEM solution are:
- Log Collection & Correlation
- Analysis & Forensics
- Response & Compliance
Most organizations find it tough to get the right combinations going, when it comes to log management and SIEM. Even before choosing your vendor, you need to need have a SIEM strategy in place. If properly planned and executed, a good log management and SIEM software, combined with process automation, can offer an excellent ROI.
To be really effective in network defense, and not just from a forensic analysis standpoint, you need to make sure that the security event data is analyzed and correlated in real time. Also, you need to capture threats in real time, correlate them in-memory and respond to the attacks in a timely manner.
Not many organizations think in terms of correlation rules because constructing the rules has been an obstacle. For example, you might be familiar with the network policies and you could even describe the business rules and objectives but the challenge is to bridge the objectives with the construction of correlation rules.
We understand this, and insist that correlation and real-time log analysis are the heart of SIEM technology. In the following blogs, we will be discussing in detail about each of the following areas:
- Infrastructure surveillance and threat intelligence from log data
- Log correlation, threat response and remediation
- Regulatory compliance for IT security
Keep an eye on this space, there is more on the way!!
