Cybersecurity is an essential aspect of any business or organization. As technology evolves, so do the threats that can harm an organization’s operations, data and reputation. One of the most effective ways to defend against these threats is through the Defense in Depth (DiD) approach.

DiD is a cybersecurity approach in which multiple defensive methods are layered to protect a business. Since no individual security measure is guaranteed to endure every attack, combining several layers of security is more effective.

This layering approach was first conceived by the National Security Agency (NSA) and is inspired by a military tactic with the same name. In the military, layers of defense help buy time.

However, in IT, this approach is intended to prevent an incident altogether.

Essential Elements of DiD

Implementing all the elements of an effective DiD strategy can help minimize the chances of threats seeping through the cracks. These elements include:

1. Firewalls

A firewall is a security system comprised of hardware or software that can protect your network by filtering out unnecessary traffic and blocking unauthorized access to your data.

2. Intrusion Prevention and Detection Systems 

Intrusion prevention and detection systems scan the network to look for anything out of place. If a threatening activity is detected, it will alert the stakeholders and block attacks.

3. Endpoint Detection and Response (EDR) 

Endpoint detection and response (EDR) solutions constantly monitor endpoints to find suspicious or malicious behavior in real time.

Databranch is excited to announce a new detection software that we have begun implementing for our clients. The Huntress Managed Detection and Response (MDR) for Microsoft 365 secures your users with 24/7 protection.

Huntress MDR can detect and respond to early signs of cyberattacks such as unauthorized access, email manipulation, and suspicious login locations.

The software then utilizes Huntress’s 24/7 Security Operations Center (SOC) which is comprised of experts who analyze and interpret the threats. An actual Huntress employee will review these detections, provide incident reports, and will deliver actionable remediations for recovery.

4. Network Segmentation 

Once you divide your business’s network into smaller units, you can monitor data traffic between segments and safeguard them from one another.

5. The Principle of Least Privilege (PoLP)

The principle of least privilege (PoLP) is a cybersecurity concept in which a user is only granted the minimum levels of access/permissions essential to perform their task.

6. Strong Passwords 

Poor password hygiene, including default passwords like “1234” or “admin,” can put your business at risk. Equally risky is the habit of using the same passwords for multiple accounts.

To protect your accounts from being hacked, it’s essential to have strong passwords and an added layer of protection by using practices such as Multi-Factor Authentication (MFA).

7. Patch Management 

Security gaps left unattended due to poor patch management can make your business vulnerable to cyberattacks. When a new patch is delivered, deploy it immediately to prevent exploitation.

Databranch offers a Patch Management solution for our managed client’s that automates and manages service packs, hot-fixes, and patches from a single location. 

How IT service providers help defend against threats

As a Databranch client, our experienced team members will help you divide DiD into three security control areas:

1. Administrative controls

The policies and procedures of a business fall under administrative controls. These controls ensure that appropriate guidance is available and security policies are followed.

Examples include hiring practices or employee onboarding protocols, data processing and management procedures, information security policies, vendor risk management and third-party risk management frameworks, information risk management strategies, and more.

3. Technical controls

Hardware or software intended to protect systems and resources fall under technical controls.

They include firewalls, configuration management, disk/data encryption, identity authentication (IAM), vulnerability scanners, patch management, virtual private networks (VPNs), intrusion detection systems (IDS), security awareness training and more.

4. Physical controls

Anything that physically limits or prevents IT system access falls under physical controls, such as fences, keycards/badges, CCTV systems, locker rooms and more.

Don’t worry if you are struggling with developing a DiD strategy for your organization. Databranch is here to make things as simple as possible. Contact us at 716-373-4467 option 6, or [email protected] to start the process of making your organization more secure.

Cybercriminals are always looking for new ways to bypass security defenses. That’s why it’s essential to think like a hacker and adopt measures to stay ahead of them. This is what Defense in Depth (DiD) is all about.

The National Institute of Standards and Technology (NIST) defines DiD as “The application of multiple countermeasures in a layered or stepwise manner to achieve security objectives. The methodology involves layering heterogeneous security technologies in the common attack vectors to ensure that attacks missed by one technology are caught by another.”

In simple terms, DiD is a cybersecurity approach in which multiple defensive methods are layered to protect a business. Since no individual security measure can guarantee protection against every attack, combining several layers of security can be more effective.

Before you start your DiD journey, it’s crucial to stay informed about the changing threat landscape.

9 Threats to Protect Your Business Against

While there are numerous threats that businesses like yours must be aware of, let’s look at some of the most common.

 1. Ransomware 

Ransomware is a type of malware that threatens to disclose sensitive data or blocks access to files/systems by encrypting it until the victim pays a ransom. Failure to pay on time can lead to data leaks or permanent data loss.

2. Phishing/Business Email Compromise (BEC) 

Phishing involves a hacker masquerading as a genuine person/organization primarily through emails or other channels like SMS. Malicious actors use phishing to deliver links or attachments that execute actions such as extracting login credentials or installing malware.

Business email compromise (BEC) is a scam that involves cybercriminals using compromised or impersonated email accounts to manipulate victims into transferring money or sharing sensitive information.

3. Cloud Jacking

Cloud jacking, or hijacking, entails exploiting cloud vulnerabilities to steal an account holder’s information and gain server access. With more and more companies adopting cloud solutions, IT leaders are worried about cloud jacking becoming a significant concern for years to come.

4. Insider Threats 

An insider threat originates from within a business. It may happen because of current or former employees, vendors or other business partners who have access to sensitive business data. Because it originates from the inside and may or may not be premeditated, an insider threat is hard to detect.

5. Denial-of-Service/Distributed Denial-of-Service (DoS and DDoS)

These attacks are common and easy to carry out. In a DoS or DDoS attack, hackers flood the targeted system with multiple data requests, causing it to slow down or crash.

6. Artificial Intelligence (AI) and Machine Learning (ML) Hacks

Artificial intelligence (AI) and machine learning (ML) are trending topics within the IT world for their path-breaking applications. However, AI and ML help hackers more efficiently develop an in-depth understanding of how businesses guard against cyberattacks.

7. Internet of Things (IoT) Risks and Targeted Attacks

IoT devices are a favorite target of cybercriminals because of the ease of data sharing without human intervention and inadequate legislation.

8. Web Application Attacks

Vulnerabilities within web applications permit hackers to gain direct access to databases to manipulate sensitive data. Business databases are regular targets because they contain sensitive data, including Personally Identifiable Information (PII) and banking details.

9. Deepfakes

A deepfake is a cyberthreat that uses artificial intelligence to manipulate or generate audio/video content that can deceive end users into believing something untrue.
