SIEM and Log Management Built In

Worsening Threat Landscape Makes a Unified Approach Necessary

With organizations of all sizes reacting to the worsening security threat landscape, Security Information and Event Management is a hot topic. Today, there are many "single purpose" SIEM products on the market and they are generally used for security threat management and regulatory compliance. SIEM solutions include log management, event management, correlation, and more sophisticated reporting than purpose-built log management products. Both have value in the worsening threat landscape:

Preventative measures are no longer enough.

Targeted attacks and malware, as well as well-publicized data breaches and data theft are intensifying the need for businesses to be able to detect attacks, react and remediate quickly. Anti-virus and anti-malware solutions are often no longer enough USM's built-in security intelligence and monitoring capabilities are required to let you keep up with malware and security incidents.

Log management products aggregate log data (event logs and audit data) and store it for analysis.

Event logs and audit data come from almost every IT system - operating systems (e.g. Windows, Linux, etc.), network equipment (routers, switches), security devices (firewalls, web application firewalls, UTMs, intrusion detection systems), vulnerability assessment tools, and more The USM built-in log management provides the raw logs you will need for forensic analysis.

Event logs and audit data vary significantly

Every system, device, and application has their own way of providing event logs and audit data. This requires log management tools to understand how to consume and understand the logs. So log management tools will normalize logs into a common format for easier analysis. Log management tools also feature centralized aggregation of logs from all suppliers. With the built-in capabilities of USM, your logs are normalized and provided for correlation to the built-in SIEM.

Logs need to be stored securely and retained for longer periods of time to support compliance regulations.

Organizations are required by regulations such as PCI DSS, HIPAA, and SOX to centrally collect and retain logs securely and preserve the chain of custody. In addition, security analysts need to easily search, analyze, and report on the data to monitor for potential threats that impact the organizations systems and sensitive data. AlienVault USM controls the chain of custody throughout the data's entire life cycle and offers analysts a simple, intuitive incident response solution to evaluate the data and respond to threats. AlienVault USM provides both raw log data as well as normalized logs.

SIEM versus Log Management

Hunter versus Gatherer

While Log Management point products provide the basics of collecting logs, normalizing them and storing them in a central location, SIEM point products provide a more complete solution to security, operations and compliance challenges, with log management capabilities as well as more aggressive methods of handling intrusions. Whereas log management might be characterized as a "Gatherer" - collecting and storing logs, SIEM would be better characterized as a "Hunter." SIEM technology lets security practitioners go "on the hunt" for intruders in their network.

SIEMs automate much of what an analyst would have to do manually,

by providing real-time correlation and pattern detection. Using Boolean-type logic, log correlation involves looking for associated events across different systems that indicate there may be a security or operational problem. For example,If we see multiple failed logins, a privileged escalation, after hours access, and IDS alarm within a short period of time, this may indicate a security breach. This correlation capability can provide security insights that would be almost impossible for a user to identify in a typical IT environment. USM's built-in SIEM saves analyst time by correlating events to provide actionable information from massive amounts of data.

Based on SIEM analysis and correlation, alarms are fired and can be viewed.

Alarms progressively become more credible, as supporting events occur.

AlienVault USM goes above and beyond both SIEM and Log Management software.

The USM platform is an excellent solution for security, operations and compliance requirements. It provides full SIEM capabilities with the added advantage of integrated host and network IDS, visibility to netflow data and vulnerability assessment to provide comprehensive security visibility on a “single pane of glass”. Rather than having to purchase multiple point products, USM provides all of these technologies in a single console.

USM provides compliance reporting capabilities to assist in many types of regulatory compliance requirements,

which can be big time savers for IT. In addition to security and operations concerns, a growing number of organizations are required to prove regulatory compliance. In healthcare, it’s HIPAA, in nuclear energy it’s NERC CIP, in retail it’s PCI-DSS, and so on. While it can be argued that compliance does not assure security or risk management, it is often a requirement to do business at all. AlienVault's USM built-in SIEM provides compliance reporting capabilities to assist in many types of regulatory compliance requirements which can be big time-savers for IT.

SIEM provides visibility.

In incident response, it's critical to see the big picture, then be able to "drill down" and see more information about assets under attack. SIEM provides ongoing vigilance in watching for suspicious activity - even when the IT professional is not watching the alarm interface. AlienVault's USM built-in SIEM capability provides rich context information about alarms, in order to determine appropriate actions to take. Contextual information includes affected assets, the vulnerability of the assets, and situational awareness and visibility into what is going on in your network around this suspicious activity.

USM provides sophisticated reporting capabilities, above and beyond log management or SIEM.

These reports can be scheduled for delivery on a certain cadence or can be ad hoc, allowing the generation of reports for a particular interest. AlienVault's USM canned and custom reporting capabilities are very useful in terms of demonstrating regulatory compliance.

AlienVault USM catches threats wherever they exist within your network,

by combining network-based intrusion detection software (IDS) and host-based intrusion detection software (HIDS) that also includes file integrity monitoring (FIM). AlienVault USM relies on a lightweight OSSEC agent that is provisioned, managed, and monitored via our web-based console. With the built-in FIM capability, as soon as any changes to critical files are executed, an alarm can be triggered in our Alarms display. These might be changes that do not require a response; however, it’s important to monitor all activity to capture baselines, and notice any abnormalities like policy violations or potential system compromise.

SIEM and Log Management Plus Other Essential Security Tools

Single-purpose SIEM or Log Management tools are extremely valuable, but often require expensive integration efforts to bring in log files from sources such as IDS. With USM, SIEM / Event Correlation come integrated out-of-the box with a host of security tools. AlienVault USM delivers a complete view into the security of your environment by combining SIEM with automated asset discovery, vulnerability data, visibility to netflow data, network IDS, host IDS and visibility to known malicious hosts.

Faster Deployment Time

Go from install to insights in less than an hour with USM. All of the built-in security controls are pre-integrated and optimized to work together out of the box.
