Privileged user activitymonitoring and auditingwww.eventloganalyzer.com
IntroductionOf all the user accounts in your organization, privileged user accountshave the most bearing on your network security due to theiradministrative power. Your organization's sensitive data stores, criticalservers, and other important network devices are only as secure as theaccounts entrusted with their senetworkadministrators—are prime targets for external attackers looking to gain fullcontrol over your network resources. But external threats aren't the onlyproblem organizations need to worry about. Administrators may exhibitmalicious intent by abusing their privileges, or they may act carelessly withtheir credentials or systems.To add to this, multiple compliance policies such as PCI DSS and SOXmandate the thorough auditing of privileged user activity. This makesprivileged user activity monitoring not just a preference, but a necessity.This guide explains the best practices for privileged user monitoring, aswell as how EventLog Analyzer can be used to report on all your privilegedusers' activities and alert you about any suspicious activity.
Privileged user monitoring best practices1. Perform a regular inventory of critical assets and privileged accounts.In mid to large-size networks, it's important to keep track of newly added critical systems andapplications along with the privileged accounts associated with them. Track newly created users and permission changes to know which accounts' rights have been elevated. This awareness helpsyou maintain complete visibility and control over your network so that no privileged activity getsmissed.2. Enforce strong privileged account security practices.Given that privileged accounts are likely targets for attackers, it helps to enforce tight securityprotocols around them, like password complexity requirements, unique accounts for each user,clearly-defined access policies, and more. You can also track password changes and logon activityto identify any hacking attempts, anomalies in account usage, possible account sharing, and more.3. Provide only necessary permissions.Even privileged users can have too many privileges. A user may be given write access to a sensitivefolder when they only need to read it, or they may be given access to an entire database when theyonly need to work with selected records. When critical resources are accessible by severalunnecessary users, it only increases the chances of a breach. This is why privileged users must onlybe provided the rights they require.4. Maintain a separation of duties between privileged users and those auditing them.The tools and processes used to monitor your privileged users should not be managed by theprivileged users themselves. Your monitoring solution's administrators should be independent ofthe remaining network administrators. This separation of duties helps ensure that privileged userscannot tamper with their audit trails or reports. Entrust your monitoring and security auditingactivities to your security operations center (SOC).5. Report on all privileged activities.It isn't necessary to monitor all the actions of regular employees, but it is important to track allprivileged user activities. Any action taken by a privileged user, like a logon failure or configurationchange, could be an indicator of an ongoing attack, however innocent it may seem. Maintainingdetailed reports will prove useful during compliance audits or forensic investigations.
