Cybersecurity 101 - What Is Defense-In-Depth?

 

Defense-in-depth is the term that we use to describe a strategy of defense that assumes attackers will evade or bypass some of the security mechanisms put in place to stop them. Attackers are clever human beings, and when they encounter impediments to their work trying to break into a network, they sometimes find ways to get around those.

That's why it's important not just to have one layer of protection or one layer of defenses protecting your sensitive data. It's important that if attackers get past, let's say, a password in order to log in remotely, that they don't then have free range to do anything they want on the network.

Therefore, the defenses that you put in place should assume if an attacker is gotten past one point of defense, that there is something else to catch them.

One of those pieces of defense-in-depth that's very important, is someone monitoring your logs to make sure that if an attacker does get through, anything that they do after that in terms of trying to gain access to other systems, elevate their privileges by getting an administrator account, or running unusual scripts or programs, gets detected by an analyst and responded to in a timely manner to keep that attacker from doing any more harm.

Deep Dive Into Defense-In-Depth As A Cybersecurity Strategy

 

Defense-in-depth is a popular security strategy that places the applications and data (or groups of applications and data) that inhabit an architecture into designated security layers. This holistic approach aims to layer defenses across all possible areas of vulnerability, offering not just one but multiple levels of protection. Let's break it down!

Data: Starting with the most critical, we aim to protect the data itself through encryption, access controls, and data loss prevention techniques.

Application: Next, we secure the applications handling data. This includes secure coding practices, regular vulnerability scanning, and patch management.

Host: This layer focuses on securing individual user devices with antivirus software, personal firewalls, and strict access controls.

Internal Network: Here, we employ network segmentation and internal firewalls, limiting lateral movement in the event of a breach.

Perimeter: The outer shell of our digital fortress where we implement network-level defenses such as external firewalls, intrusion detection systems, and secure gateways.

Physical: Often overlooked but no less critical - securing physical access to devices and servers is a must.

Policies, Procedures & Awareness: The human factor - often the weakest link! Here we use education, training, clear policies, and procedures to strengthen our human firewall.

These layers interweave to create a multi-faceted, robust defense strategy. But remember, no castle was ever impregnable! Constant vigilance, regular updates, and evolution in line with emerging threats are vital to maintaining security.

Insights On Defense In Depth For Network Security (VIDEO)

 

There are many aspects to the security of a system, but the Defense in Depth strategy guides them all.

There is no one thing that provides full security for a system. All too often people think they’re secure, as they have a firewall.

Unfortunately, that’s not true. Firewalls are important, but they’re not where security begins and ends.

Cyber Security needs to be layered. Consider an example of a virus being sent through email. Will the firewall pick it up? Possibly not. We rely on email security systems, and antivirus software on the workstations. If one part of this fails, there’s still another part to rely on.
