How Adopting the Defense-in-Depth Cybersecurity Approach Can Boost Protection

In today’s cybersecurity landscape, the increased influence of the digital era has resulted in a parallel, if not greater, increase in cyber-attacks for businesses. Each day, reports of massive data breaches and damaging cyberattacks have become all too common. Ransomware, phishing attacks, and malware attacks continue to dominate headlines, causing financial losses, disruption, and downtime.

According to Statista, 20% of Australian organisations in 2021 experienced ten or more successful cyber-attacks. This research has proven that as the volume and sophistication of cyber threats grow, no industry is immune, and no target is too small. 

Therefore for your organisation to strive in this digital era, you must develop strong security strategies that can detect and mitigate cyber-attacks. There are so many cybersecurity strategies to use; however, with the advancement in cyberattacks, a single layer of security cannot protect your organisation. Therefore, it is time for your business to adopt a multi-layered approach to cybersecurity. This comes in the form of a Defense-in-Depth strategy.  

Defense in depth is a proven strategy in which organisations use multiple layers of security to protect assets from a wide range of cyber-attacks. This article will explore how adopting the Defense-in-Depth cybersecurity approach can boost protection. 

What is Defense-in-Depth?

Defense-in-Depth is one of the best and most proactive cybersecurity measures a business can adopt when a security system is breached or compromised. It is a multi-layered defensive strategy that employs multiple layers of sophisticated security controls to protect sensitive data and information from a variety of cyber threats. These multiple layers work together to protect your entire business’s endpoints, valuable data, software, and networks. 

The primary goal is to make it difficult for cyber-attackers to penetrate networks and steal data, thereby preventing cyber threats from occurring.

When it comes to cybersecurity, it is known that no single mechanism can completely thwart a cyber threat. However, with a strong defense-in-depth cybersecurity approach, the reduction and disability of an ongoing attack, as well as the prevention of additional damage is possible.

This is due to the principle that defense-in-depth stands for – that no single security control is perfect and that a grouping of effective and strong security controls can provide better protection against cyber attacks. As a result, a strong defense-in-depth cybersecurity strategy assists organisations in addressing cyber threats and attacks before they succeed, lowering cybersecurity risk.

How Does Defense-in-Depth Cybersecurity Approach Help?

With today’s fast-growing, ever-changing, and intelligent cybercrime landscape, having one layer of security will simply be ineffective. This is why the defense-in-depth cybersecurity approach builds a more secure network by layering and even replicating certain security measures to reduce the likelihood of a breach.

By bringing together various defense mechanisms such as antivirus, intrusion detection, port scanning, firewalls, secure gateways, and more to form a layer, your business can close loopholes and openings and fill gaps that would happen if your business has and relies on one layer of security.

Why You Need to Adopt This Approach 

There are several major reasons why it is essential for your business to adopt the defense-in-depth cybersecurity strategy. These include:

  • Provides redundancy

In the event of a cyber-attack, the provision of redundancy by defense-in-depth allows your business network or security platform to remain active by providing a different data path or acts as a backup. Therefore, since no single layer of security is perfect, combining multiple layers increases your chances of detecting and stopping threats. 

  • Reduces successful attacks

With the defense-in-depth approach in place, if one layer fails, you can be assured that you have more layers available to stop the intruder, thereby reducing successful attacks.

  • Address a variety of threats and adapt to new ones.

Due to the multiple security strategies that are created to form a layer, defense-in-depth has the ability to tackle and protect against various cyber threats and attacks. Also, it had the ability to adapt to new threats. As new vulnerabilities emerge you can add layers to counter them.

How Adopting the Defense-in-Depth Cybersecurity Approach Can Boost Protection

Adopting a defense-in-depth strategy can your organisation boost its protection, reduce the likelihood of successful attacks and improve its overall security infrastructure in the following ways 

Network Segmentation 

This is a type of network security technique that divides a large network into smaller chunks of sub-networks. It enables network teams to separate sub-networks while providing each with independent security controls and services.

Network segmentation assists organisations in preventing insider threats from breaching the network and accessing sensitive data such as customer data, financial information, and intellectual property (IP). Network segmentation is used by organisations to improve monitoring, reduce technical difficulties, maximise performance, and balance security.

Reducing Single Points of Failure

The defense-in-depth approach with its approach of having more than one layer of security, reduces the probability of getting a single point of failure. If one layer of defense is breached, other layers will remain to provide protection. 

Data Loss Prevention 

With a defense-in-depth cybersecurity approach, the prevention of data loss is made possible. This is because out of its multiple layers, one or two cybersecurity solutions are present to detect and prevent unauthorised data transfers, accidental data sharing, and data breaches. It also safeguards critical intellectual property for your company and aids in data security and regulatory compliance.

Strong Authentication Processes

The defense-in-depth model includes various strong authentication strategies that serve as a strong line of defense in the fight against cyber threats and attacks. The authentication process includes two-factor or multifactor authentication, as well as single sign-on, in addition to strong password security and biometrics to boost your business’s protection. To get the best authentication process, there are best practices to deploy multi-factor authentication at your company. 

Accessing Control

The defense-in-depth strategy also includes a variety of access controls that are beneficial for employees and devices. With the adoption of the defense-in-depth cybersecurity approach, IT teams can use timed access control to manage network access based on specific time frames.

Encrypt Data

Encryption is a data security method that is essential in the fight against cyber-attacks. Defense-in-depth offers encryption. This means information is converted to encrypted data, and only those with the key can decrypt the code and access the original written data. This layer protects data from brute-force attacks as well as cyber threats such as phishing attacks, ransomware, malware, and other cyber threats. It also prevents hackers from reading and interpreting sensitive information.
