The extra invaluable a possession, the extra steps you’re taking to guard it. A house, for instance, is protected by the lock methods on doorways and home windows, however the invaluable or delicate objects {that a} legal would possibly steal are saved with much more security — in a locked submitting cupboard or a protected. This gives layers of safety for the stuff you actually don’t desire a thief to get their fingers on. You tailor every merchandise’s safety accordingly, relying on its value to you and the probability of theft.
Your company community and information are the identical. Defending the dear belongings inside your community requires layers. Usually referred to as protection in depth, this technique presents a number of ranges of security instruments and methods which are designed to protect towards assaults.
Nonetheless, these security methods aren’t good, and that’s precisely what risk actors are decided to take advantage of. In your house, you will have put the jewels within the protected, but when the protected isn’t locked, anybody can acquire entry. Similar along with your SOC. In case your protection system has gaps, it’s solely a matter of time earlier than somebody will acquire entry to your information.
Concern of patching
Having a state-of-the-art security system that seems to cowl each sort of assault is nice, however you will not be addressing how risk actors entry your system or what they’re searching for. Adversaries don’t like change, Phil Neray, VP of cyber protection technique at CardinalOps, mentioned at Splunk’s .conf23 occasion. Stolen credentials and exploited vulnerabilities stay the preferred assault vectors, in keeping with Verizon’s Data Breach Investigations Report.
But when customers throughout the firm are falling for phishing scams or ignoring patch updates, it now not issues how strong your layers are. Risk actors will discover their manner inside.
And why do individuals ignore patching? They worry a scarcity of availability to their system whereas the patches and updates are put in place.

Transferring via the community
There’s an inclination to think about layers by way of high to backside or left to proper — if you happen to can’t cease them at level A, then there may be protection at level B. However that usually ignores how risk actors really transfer throughout the system. Relying on the kind of assault, they’re transferring wherever they see a gap, and one missed layer of safety can impair defenses, reminiscent of missed encryption on passwords saved in an in any other case well-defended vault.
Your layered defenses are additionally solely as robust as your means to detect anomalies or intrusions. Neray supplied 4 inquiries to ask when wanting on the high quality of detections in your layered protection:
- The place are you lacking detections?
- Are detections damaged or too noisy?
- How do you shortly onboard new detections?
- How are you leveraging automation?
Every detection ought to cowl a number of security layers relatively than only a single location, Neray acknowledged.
Embrace refined defenses
You need extra than simply layers, however threat-informed defenses based mostly on the threats distinctive to your group, mentioned Neray. When you perceive what you’re defending and the place these belongings are saved, you may construct your layers of safety to defend towards these threats.
