  • Monitor all access attempts, look for anomalous ones
  • Look for anomalies in the VPN access to your network
  • Monitor privileged accounts, service accounts with utmost caution
  • Check for unusual access to sensitive company data
  • Monitor all shared accounts
  • Monitor all infrastructure resources
  • Assess, correlate data from all sources
  • Assess users in their own peer groups

Look for spikes in activity
Spikes in activity, for example too many file modifications or an unusually great number of login attempts by a particular account could be an indication of a threat. Hence, as part of threat detection, it’s very important to look for spikes in activity. Once you notice a spike, you should investigate it to find out if it’s really a threat or not.

Monitor all access attempts, look for anomalous ones…
It’s very important that you keep an eye on all access attempts and look for anomalous ones, if any. Keep checking and if there is any unusual change in the frequency and volume of logins, successful ones and failed ones as well, do a thorough check. You should also focus on any activity that happens after business hours and anything that’s a deviation from usual activities.

Look for anomalies in the VPN access to your network
Any anomaly that you spot in the VPN access to your enterprise network- abnormal volume or speed, or something fishy in the geographical location could be indicative of a potential threat. Look for such anomalies and if you notice any, analyze them to ensure if it’s a threat or not.

Monitor privileged accounts, service accounts with utmost caution
Privileged accounts in an enterprise are meant to be used rarely. Likewise, privileged accounts as well as service accounts are supposed to be used only for carrying out certain tasks that other accounts they are not authorized to perform. Hence you have to monitor activities of such accounts very carefully and if there’s anything unusual or any policy violation happening, check it out.

You should always check for unusual access to sensitive company data. Things like a high number of access events, access to different files, happening over a short span of time etc should be reviewed.

Monitor all shared accounts
You must identify and monitor all shared accounts in your organization’s network. This is important to ensure effective security for any company. Such accounts should be monitored and all risk factors need to be analyzed; information security breaches happen greatly from such accounts.

Assess users in their own peer groups
Always make it a point to assess users in their peer groups. Don’t go applying the same set of rules to every department or every individual, judge them based on rules that apply to their department or the nature of their work.
