Ways to Build a Multi-Layered Industrial Cyber Defense Strategy


In today’s fast-changing digital world, using outdated methods to protect against cyber dangers isn’t enough. To fight modern online attacks, a multi-layered industrial cyber defense plan is essential.

This approach uses different tools and methods at various levels to create substantial barriers that are hard for bad actors to break through. In the grand scheme, this strategy offers better protection against the increasingly tricky online threats we face.

The Growing Imperative of Multi-Layered Security

As the 2023 OpenText Cybersecurity Threat Report shows, wrong links concealed in elusive ways are increasing rapidly. This shows us that cyber threats are getting worse, and older types of security aren’t good enough.

Hackers are now using advanced methods to attack, and relying on only one security tool like antivirus software or firewalls won’t work. Cyber attackers are using complicated attacks that involve sneaking into networks, hiding their presence, and slowly stealing information.

To defend against these threats, just reacting to problems won’t have a lasting impact. Companies need to use many different methods together to protect against attacks from different angles. This way, they can stop threats at many points. For example, while next-gen antivirus fights against harmful software, network monitoring can catch suspicious activity, and data controls can prevent unauthorized access.

Hackers are constantly finding new ways to attack, and having this extra protection is pivotal. Old solutions can only handle some of the different ways hackers attack nowadays. Even though companies use security tools, surveys show that many of them still have security breaches. What this points out is the fact that clearly there’s a need for improvement in cybersecurity measures.

By using many layers of protection, organizations can keep their important things safe and stay ahead of attackers through OT security solutions, designed to face specific cybersecurity issues in operational technology surroundings.

Understanding Multi-Layered Security

Imagine building a team of special guards dedicated to protecting your online world. Each guard has a particular job – some watch the entrances like firewalls, and some look for anything strange like a security guard, however, they all work together to keep things safe. Multilayered security functions exactly like this, with your networks, apps, devices, and data all protected from a varied range of attacks.

It’s like having a safety net with different layers. If one layer misses something, another layer catches it. This makes your security stronger and smarter. Compare this to having just one guard at the gate. If that guard fails, there’s nothing else to stop problems.

Every day, about 20,000 new bad websites appear online. Even websites you trust can be taken over by hackers, which is why more than one security measure is needed. In doing this, imagine protecting your home with a strong door, guards, alarms, and secret codes.

These layers of security work together to keep you safe, mainly because threats are always changing. So, having many layers is like having a dedicated team of guards in your online world.

The Diverse Cyber Risks Addressed

Imagine you’re setting up a shield to protect something important, like a treasure chest. Cybersecurity works the same way. Multi-layered security is like building a strong and flexible shield with different layers.

This shield defends against various types of online attacks – both sneaky ones that try to steal information without you knowing and bold ones that try to break into systems and cause trouble.

Facing Passive Threats:

Sneaky Thieves: These are cyber threats that try to steal quietly. They want sensitive information like passwords without causing problems. Think of them as digital spies.

Protection Layers: To fight threats like these, multi-layered security uses tools like encryption. It’s like locking information in a secret code that only you and the right person can understand. There’s also something called anomaly detection. This watches for unusual activities that might mean something is wrong.

Dealing with Active Threats:

Bold Attackers: These threats are much like attackers storming a castle. They try to break through defenses and cause trouble in a forceful or brutish manner. This can include hackers trying to break into systems, make websites crash, or pretend to be someone they’re not.

Protection Layers: Multi-layered security uses a mix of methods to fight these bold threats. Firewalls act like strong walls around your digital space, deciding who can come in and who can’t. Intrusion Detection Systems (IDS) are like watchful guards that spot anything unusual and raise an alarm. Endpoint security protects individual devices from being taken over. Access controls make sure only the right people can get into specific areas.

Why Multi-Layered Security Matters:

Online, there’s a constant battle between those trying to steal or cause trouble and those trying to keep things safe. Multi-layered security combines different protections to fight this battle. It’s like having different types of guards – sharp-eyed and strong – all working together to watch from different angles.

So, Multi-layered security is equipped to tackle both passive and active cyber assaults means this approach creates a strong defense ready to handle different types of online threats, whether they’re trying to sneak in unnoticed or launch a direct attack.

Why Enterprise Networks Are Highly Vulnerable

Given their wealth of sensitive information and access to critical infrastructure, enterprise networks are prime targets for hackers. Additional factors amplifying their appeal include:

  • Abundance of connected devices: The average company network has over 100 vulnerable endpoints.
  • Integration of online apps: Cloud apps provide gateways for cybercriminals.
  • Financial allure: Stealing data for profit is a key motivator.
  • Consumerization of IT: BYOD policies increase exposure.
  • Interdependent web ecosystem: Third parties pose inherent risks.

According to Refinitiv Cyber Research, spear phishing emails grew 16.4% year-on-year, constituting over 8% of all email traffic. This reveals the focus on infiltrating enterprise networks.

Anatomy of a Sophisticated Cyber Attack

Modern attacks unfold systematically:

  • Reconnaissance: Gathering information on the target network.
  • Initial intrusion: Gaining an initial foothold via phishing or exploiting vulnerabilities.
  • Establishing persistence: Installing backdoors, trojans, and keyloggers to maintain presence.
  • Internal reconnaissance: Exploring the compromised system and expanding access.
  • Data exfiltration: Stealing and transmitting confidential data externally.

Building a Multi-Layered Security Approach

A robust, integrated system entails protecting:

  • Physical infrastructure: Using smart cards or biometric access controls.
  • Network perimeter: Leveraging next-gen firewalls, web/email gateways, IDS, DDoS prevention, and network segmentation.
  • Endpoints: Employing advanced antivirus, host-based firewalls, patch management, and containerization.
  • Applications: Incorporating security into app design via authentication, encryption, and input validation.
  • Data: Enforcing access controls, data loss prevention, rights management, and database security.

The Power of Redundancy

A big benefit of multi-layered security is having extra protection. With many protections at different levels, organizations can stop attacks at different points and prevent data breaches.

Studies show that using three layers of protection reduces problems by 40.3%. This means if one protection fails, the others can still help.

For example, while one tool can stop bad websites, another can catch strange activity. Combining these can stop attacks. Also, firewalls stop bad things from coming in, but they might miss attacks leaving. Other tools can catch that.

This way of having many protections also makes attackers think twice. They see many barriers and might give up. The key is to make all these protections work together. With a good plan, multi-layered security can stop attacks and keep things safe.

Key Takeaway

Given the alarming range of threats, enterprises must adopt a proactive cyber defense strategy spanning across people, processes, and technology. While multi-layered security demands greater coordination, its unparalleled coverage curbs risks substantially.

By implementing overlapping controls and fostering a security-first culture, organizations can stay a step ahead of motivated attackers.
