This is the last in this year’s, GreyBeards-RackTop Systems podcast series and once again we are talking with Jonathan Halstuch (@JAHGT), Co-Founder and CTO, RackTop Systems. This time we discuss why traditional security practices can’t cut it alone, anymore. Listen to the podcast to learn more.

Turns out traditional security practices are keeping the bad guys out or supplies perimeter security with networking equivalents. But the problem is sometimes the bad guy is internal and at other times the bad guys pretend to be good guys with good credentials. Both of these aren’t something that networking or perimeter security can catch.

As a result, the enterprise needs both traditional security practices as well as something else. Something that operates inside the network, in a more centralized place, that can be used to detect bad behavior in real time.

Jonathan talked about a typical attack:

A phishing email link is clicked on ==> attacker now owns the laptop/desktop user’s credentials
Attacker scans the laptop/desktop for admin credentials or one time pass codes which can be just as good, in some cases ==> the attacker attempts to escalate privileges above the user and starts scanning customer data for anything worthwhile to steal, e.g. crypto wallets, passwords, client data, IP, etc.
Attacker copies data of interest and continues to scan for more data and to escalate privileges ==> by now if not later, your data is compromised, either it’s in the hands of others that may want to harm you or extract money from you or it’s been copied by a competitor, or worse a nation state.
At some point the attacker has scanned and copied any data of interest ==> at this point, depending on the attacker, they could install malware which can be easily detected to signal the IT organization it’s been compromised.

By the time security systems detect the malware, the attacker has been in your systems and all over your network for months, and it’s way too late to stop them from doing anything they want with your data.

In the past detection like this could have been 3rd party tools that scanned backups for malware or storage systems copying logs to be assessed, on a periodic basis.

The problem with such tools is that they always lag behind the time when the theft/corruption has occurred.

The need to detect in real time, at something like the storage system, is self-evident. The storage is the central point of access to data. If you could detect illegal or bad behavior there, and stop it before it could cause more harm that would be ideal.

In the past, storage system processors were extremely busy, just doing IO. But with today’s modern, multi-core, NUMA CPUs, this is no longer be the case.

Along with high performing IO, RackTop Systems supports user and admin behavioral analysis and activity assessors. These processes run continuously, monitoring user and admin IO and command activity, looking for known, bad or suspect behaviors.

When such behavior is detected, the storage system can prevent further access automatically, if so configured, or at a minimum, warn the security operations center (SOC) that suspicious behavior is happening and inform SOC of who is doing what. In this case, with a click of a link in the warning message, SOC admins can immediately stop the activity.

If it turns out the suspicious behavior was illegal, having the detection at the storage system can also provide SOC a list of files that have been accessed/changed/deleted by the user/admin. With these lists, SOC has a rapid assessment of what’s at risk or been lost.

Jonathan and I talked about RackTop Systems deployment options, which span physical appliances, SAN gateways to virtual appliances. Jonathan mentioned that RackTop Systems has a free trial offer using their virtual appliance that any costumer can download to try them out.
